Many people drink coffee for an energy boost, but do you know that it can also prolong your life? A study published in the journal Circulation revealed that moderate amounts — or less than five cups — of coffee each day can lower your risk of death from many diseases, such as cardiovascular disease, Type 2 diabetes, and nervous system disorders. It can also lower death risk due to suicide.

The study’s researchers explained this effect could be attributed to coffee’s naturally occurring chemical compounds. These bioactive compounds reduce insulin resistance and systematic inflammation, which might be responsible for the association between coffee and mortality. (Related: Coffee drinkers have a lower mortality rate and lower risk of various cancers.)

The researchers reached this conclusion after analyzing the coffee consumption every four years of participants from three large studies: 74,890 women in the Nurses’ Health Study; 93,054 women in the Nurses’ Health Study 2; and 40,557 men in the Health Professionals Follow-up Study. They did this by using validated food questionnaires. During the follow-up period of up to 30 years, 19,524 women and 12,432 men died from different causes.

They found that people who often consumed coffee tend to smoke cigarettes and drink alcohol. To differentiate the effects of coffee from smoking, they carried out their analysis again among non-smokers. Through this, the protective benefits of coffee on deaths became even more apparent.

With these findings, the researchers suggested that regular intake of coffee could be included as part of a healthy, balanced diet. However, pregnant women and children should consider the potential high intake of caffeine from coffee or other drinks.

Because the study was not designed to show a direct cause and effect relationship between coffee consumption and dying from illness, the researchers noted that the findings should be interpreted with caution. Still, this study contributes to the claim that moderate consumption of coffee offers health benefits.

The many benefits of coffee

Many studies have shown that drinking a cup of coffee provides health benefits. Here are some of them:

  • Coffee helps prevent diabetes: A study conducted by University of California, Los Angeles (UCLA) researchers showed that drinking coffee helps prevent Type 2 diabetes by increasing levels of the protein sex hormone-binding globulin (SHBG), which regulates hormones that influence the development of Type 2 diabetes. Researchers from Harvard School of Public Health (HSPH) also found that increased coffee intake may lower Type 2 diabetes risk.
  • Coffee protects against Parkinson’s disease: Studies have shown that consuming more coffee and caffeine may significantly lower the risk of Parkinson’s disease. It has also been reported that the caffeine content of coffee may help control movement in people with Parkinson’s disease.
  • Coffee keeps the liver healthy: Coffee has some protective effects on the liver. Studies have shown that regular intake of coffee can protect against liver diseases, such as primary sclerosing cholangitis (PSC) and cirrhosis of the liver, especially alcoholic cirrhosis. Drinking decaffeinated coffee also decreases liver enzyme levels. Research has also shown that coffee may help ward off cancer. A study by Italian researchers revealed that coffee intake cuts the risk of liver cancer by up to 40 percent. Moreover, some of the results indicate that drinking three cups of coffee a day may reduce liver cancer risk by more than 50 percent.
  • Coffee prevents heart disease: A study conducted by Beth Israel Deaconess Medical Center (BIDMC) and HSPC researchers showed that moderate coffee intake, or two European cups, each day prevents heart failure. Drinking four European cups a day can lower heart failure risk by 11 percent.

This Is The Best Time of Day to Drink Coffee to Stay Alert But Still Sleep

main article image

I need a caffeine boost in the morning to properly function.

And I’m not alone – according to a Reuters study, 65 percent of Americans have coffee every day, and more than 85% drink it regularly.

But, according to CNBC, there’s a specific time of day you should drink your coffee if you want to feel the best results.

Laura Cipullo, a registered dietitian and author of Women’s Health Body Clock Diet, told CNBC that drinking your morning coffee as soon as you wake up could cause jitters and make you feel too hyper.

The sweet spot, she said, is a few hours later.

When you first wake up, your body is full of the stress hormone cortisol, which can make you feel anxious anyway.

Adding caffeine into the mix can only elevate this response. It can also make you feel tired and sluggish later on, so you’re better off drinking coffee later in the morning, or simply getting enough sleep the night before.

“Have coffee when the body is producing less cortisol, about three to four hours after waking,” Cipullo said – so between 9 am and 11 am.

Whatever you do, try not to drink coffee in the evening, as caffeine can stay in your system and affect your wakefulness for up to six hours, even though the effect peaks about 30 to 60 minutes after consumption.

Research has shown coffee has various health benefits. It has been connected to better health and a longer life, and having coffee as part of your diet may protect against heart disease, cancer, and dementia.

But it’s important to drink it in moderation, because too much caffeine may cause symptoms of anxiety, irritability, and insomnia.

Coffee May Have Bigger Effect on You Than Thought

Coffee has been tied to many health benefits. Now, a small study suggests a daily java habit may affect the body’s metabolism more extensively than thought.

The study, of 47 adults, found that heavy coffee consumption — four to eight cups a day — altered blood levels of more than 100 metabolites. That refers to a broad range of chemicals that change after eating or drinking.

Many of the effects were expected, researchers said, but a few were surprising.

For example, coffee cut levels of certain metabolites related to the endocannabinoid system — the same system affected by marijuana. This reduction is the opposite of what happens when you take pot, the researchers said.

What does it all mean? That’s not clear.

But many studies have found that coffee drinkers typically have lower risks of various diseases than nondrinkers do, explained Marilyn Cornelis, the lead researcher on the new work.

The possible benefits include lower risks of Parkinson’s disease, diabetes, multiple sclerosis and certain cancers.

“But most of those studies are just looking at associations,” said Cornelis, an assistant professor of preventive medicine at Northwestern University’s Feinberg School of Medicine in Chicago. “They looked at people’s self-reported coffee intake and their risk of disease.”

This study, she explained, tried to “get more at the mechanisms — the biology that might be underlying those associations.”

The findings, published March 15 in the Journal of Internal Medicine, come from a clinical trial that involved 47 Finnish adults. All were habitual coffee drinkers.

Researchers had them abstain from coffee for one month, then drink four cups per day the next month, and eight cups a day the following month. Blood samples were collected at the end of each month.

In general, coffee consumption triggered many expected changes in metabolism, Cornelis said.

But her team also spotted some previously unknown effects. Besides the endocannabinoid changes, there were shifts in certain metabolites related to the steroid system and fatty acid metabolism. The steroid system includes cholesterol and hormones such as testosterone and estrogen.

Whether there are implications for people’s health, however, is unknown.

“We hope that this will be hypothesis-generating,” Cornelis said. Future studies, she explained, could dig into the connection between coffee and endocannabinoid metabolites, for example — to see whether it helps explain why coffee drinkers have lower risks of certain diseases.

The endocannabinoid system helps regulate a range of body functions, Cornelis noted. These include blood pressure, sleep, appetite and calorie-burning. Coffee has been linked to better weight control, and it’s possible, she said, that its effects on endocannabinoids play some role.

She said the effects of coffee were the opposite of what you’d expect with marijuana — which is a famous trigger of the “munchies.”

For now, though, it’s hard to know what to make of the findings, said Angela Lemond, a spokesperson with the Academy of Nutrition and Dietetics. She was not involved with the research.

The study was small, Lemond said, and it set up an artificial situation where people went from no coffee to four cups a day, then jumped to eight daily.

“That’s going from zero caffeine to about 400 milligrams a day, then 800,” Lemond pointed out.

It’s not clear, she said, whether the metabolite changes reflect what happens with people’s typical coffee-drinking habits.

Right now, Lemond noted, U.S. dietary guidelines say that adults can safely consume up to 400 milligrams of caffeine a day — or, roughly, what these study participants downed in month two.

But if you do drink that much coffee, you should not load it with cream and sugar, Lemond stressed.

“You also need to look at your total day,” she said. “People often don’t realize what their caffeine intake is from sources like soda or tea.”

Beyond that, Lemond said, people should think about caffeine’s impact on their anxiety levels or sleep problems.

If you drink coffee in lieu of sleep, she noted, that’s a problem. “So many people are sleep-deprived,” Lemond said. “Even if there is a health benefit from coffee, that sleep deprivation will cancel it out.”

What Drinking Coffee Actually Does To Your Body

Its effects may appear to be magical, but there’s a lot happening under the surface when you’re enjoying your morning mug.

Whether you just like the taste of coffee, drink it out of habit, or truly rely on it for energy, it’s no secret the drink has magical powers. But have you ever thought about what it’s actually doing after you gulp down your morning mug?

Coffee comes from a bean, so it contains phytonutrients and polyphenols, chemical compounds found in plants that are believed to have antioxidant benefits, Dana Hunnes, Ph.D., M.P.H., R.D., senior dietician at UCLA Medical Center and adjunct assistant professor at the Fielding School of Public Health, tells SELF. “But for the most part, caffeine tends to be the nutrient in coffee that people are most aware of and that’s the best studied.”

From your brain to your bowels, coffee does work on your body. Here’s what’s really happening when you drink it.

The caffeine enters your bloodstream and quickly finds its way to your brain, where it works as a stimulant and boosts alertness and energy.

“The chemical enters your bloodstream fairly quickly,” Hunnes says. It can take as few as 10 minutes from drinking for caffeine to start working. Caffeine binds to adenosine receptors in the brain. Adenosine is a nervous system depressant, meaning its presence suppresses arousal and promotes sleep. When caffeine intrudes and binds to the receptors, adenosine’s effects are lessened, and we become stimulated. This increased brain activity then stimulates the release of adrenaline, which is what gives us that big burst of energy and attentiveness associated with a morning cup of Joe. Studies also have connected caffeine consumption to a boost in memory.

The downside is that drinking too much can cause insomnia.

“If you have caffeine later in the day, it can actually predispose you to develop insomnia or make it worse if you already have it,” Rachel Salas, M.D., an associate professor of neurology at Johns Hopkins Medicine who specializes in sleep medicine, tells SELF. It can keep anyone up if they drink it too close to bedtime, but if you’re prone to develop insomnia, a coffee habit can be the trigger that causes a chronic problem. Salas suggests stopping coffee (and all other caffeine) consumption at noon if you think it may be impacting your ability to fall asleep at night. If you can’t function before your morning cup, it’s a red flag you need to take a look at your sleep habits. Coffee is a helpful crutch when you’re tired, but it’s not going to actually give you more energy in the long term. Only good sleep can do that.

That’s partially because caffeine stays in your system for hours and hours.

“The way we metabolize coffee is called a half-life,” Hunnes says. In most people, caffeine’s half-life is 4 to 6 hours. “It takes about 6 hours to reduce the amount of caffeine in our blood by about 50 percent,” she explains. So if you drink a 200 mg cup at 9 AM, by 3 PM you’ll have 100 mg left, and by 9 PM you’ll have 50 mg. Keep in mind, that’s the average half-life—how quickly you metabolize caffeine really depends on your individual body chemistry and genetics.

Caffeine also impacts our pleasure centers, which improves our mood…and keeps us hooked.

“It can help you be more alert and reactive, but it can also help pep you up and impactyour mood,” Salas says. Like most drugs, caffeine in coffee increases the levels of feel-good chemical dopamine in our brains. (Other stimulants like cocaine have the same effect, but just much stronger.) This can improve our moods and increase happiness. But for daily drinkers, this can create dependence, resulting in withdrawal symptoms when you go without—it’s why habitual users tend to wake up grumpy and get headaches if they don’t get their fix.

Too much caffeine can have a negative impact on mood and mental health.

High doses can mess with your brain chemistry too much, and cause jitteriness and nervousness. Studies have shown that high doses of caffeine can increase anxiety and panic attacks. Those who already struggle with these mental health challenges tend to be more sensitive to caffeine and its mood-altering effects.

Drinking large amounts of coffee can cause a spike in blood pressure and heart rate.

Studies have suggested that coffee increases heart rate, thanks to caffeine’s impact on hormones and neurotransmitters. But drinking coffee in moderation—one to three cups per day–shouldn’t have a noticeable impact on a healthy adult. According to the Mayo Clinic, some habitual drinkers may have a slightly higher blood pressure, while others develop a tolerance and are not affected in the long term. There isn’t a clear explanation as to why caffeine causes this increase in blood pressure, but it’s likely due to increased adrenaline and other hormonal responses brought on by the stimulant.

Coffee stimulates bowel movements, and may even reduce the risk of gallstones.

Ever notice you really have to hit the bathroom after a cup of coffee? Experts believe caffeine directly stimulates the colonic muscles, prompting bowel movements. Plus, if you’re drinking it hot, the warm liquid itself can help relax the colon and prompt muscle contractions, adding to the laxative effect. When the muscles in the gallbladder specifically are stimulated, it increases emptying, which can reduce the risk of gallstones.

It’s a myth that coffee is dehydrating.

“It’s a very mild diuretic,” Hunnes says. “But it’s not really much of a dehydrator.” She says that if you were to drink a huge amount in one day, say 8 cups (which is not recommended), and have no other fluids all day, you might experience slight dehydration. But coffee contains a lot of water, and it counts toward your daily fluid intake just like a plain glass of H2O would.

Coffee may suppress appetite and boost calorie burn, but it’s not a magic weight-loss bullet (sorry).

Coffee is a known appetite suppressant and may stimulate thermogenesis, or the process our bodies use to create heat, which theoretically leads us to burn more calories. But there’s not much evidence that these effects are large enough to result in significant or long-term weight loss, the Mayo Clinic says. Black coffee is a good low-cal way to get your fix, but choking it down for its supposed weight-loss benefits probably won’t bring any noticeable changes.

More Coffee May Up Metabolic Syndrome Risk in Type 1 Diabetes

In a snapshot cross-sectional analysis of study participants with type 1 diabetes in Finland, drinking three or more cups of filtered coffee a day was associated with increased odds of having metabolic syndrome, in contrast to previous findings in the general population.

The article, by B Stutz of the University of Helsinki, Finland, and colleagues, based on data from the Finnish Diabetic Nephropathy (FinnDiane) study, was published online February 1 in Nutrition, Metabolism & Cardiovascular Diseases.

“In contrast to the previous observations in other populations, coffee consumption was associated with higher odds of [metabolic syndrome] in the current study” in people with type 1 diabetes, the researchers report.

Among these individuals with type 1 diabetes, those who drank moderate or high amounts of coffee had a significantly increased risk of metabolic syndrome compared with those who did not drink coffee, after adjusting for multiple variables.

Those who drank any amount of coffee were more likely to have hypertension.

The reasons for these findings remain to be determined and more study is also needed to see how coffee consumption might affect health outcomes in people with type 1 diabetes, the researchers conclude.

Association Mainly Driven by Hypertension

In the general population, regular coffee drinkers have been reported to have a lower risk of developing metabolic syndrome, and thus a lower risk of cardiovascular disease and early mortality.

However, it has not been clear whether patients with type 1 diabetes who are regular coffee drinkers would also have a lower risk of metabolic syndrome.

To investigate this, researchers examined 1040 participants from the FinnDiane study who had type 1 diabetes — defined as diabetes onset before age 35 years and permanent insulin therapy within a year of diagnosis — and complete data from a diet questionnaire along with information on metabolic syndrome criteria.

Metabolic syndrome was defined as having three of the following five criteria: waist circumference ≥ 94 cm in men and ≥ 80 cm in women; triglycerides ≥ 1.7 mmol/L or on lipid-lowering medication; high-density lipoprotein cholesterol (HDL-C) < 1.0 mmol/L in men and < 1.3 mmol/L in women, or on medication to increase HDL-C; blood pressure ≥ 130/85 mmHg or use of antihypertensive medication; and fasting blood glucose ≥ 110 mg/dL.

Participants were classed as having the following coffee consumption levels:

  • None: < 1 cup/day, 134 participants (13%)
  • Low: 1–2 cups/day, 230 participants (22%)
  • Moderate: 3–4 cups/day, 371 participants (36%)
  • High: ≥ 5 cups/day, 305 participants (29%)

Of the 906 coffee drinkers, 825 (91%) drank filtered coffee, so researchers pooled data for the different types of coffee.

On average, individuals who did not drink coffee were 40 years old and had diabetes for 21 years, whereas coffee drinkers were older (mean age 46 to 49 years) and had diabetes longer (mean duration 27 to 30 years).

There were more current smokers in the group that had a high consumption of coffee (22%) than in the groups that drank less (up to 12%) or no coffee (3%).

There were also more men in the group who drank 5 or more cups of coffee a day (60%) than in the groups that drank less or no coffee (32% to 45%).

Coffee drinkers were more likely to be taking antihypertensive or lipid-lowering medications than nondrinkers.

The prevalence of metabolic syndrome increased stepwise from 51% to 64% to 65% to 70% among people whose coffee consumption was none, low, moderate, or high, respectively.

Compared with noncoffee drinkers, those who drank 3 or 4 cups a day had a 1.8-fold increased risk of having metabolic syndrome, and those who drank 5 or more cups a day had a 2.1-fold increased risk (P < .05 for both), after adjusting for age, sex, total calories, alcohol, physical activity, and smoking.

Similarly, compared with noncoffee drinkers, those who drank 1 or more cups of coffee a day had a 2.2- to 2.8-fold increased risk of hypertension, after adjusting for multiple variables (P < .05).

“The association between coffee consumption and [metabolic syndrome] seems to be mainly driven by the blood pressure component,” Stutz and colleagues observe.

California Might Soon Put a Cancer Warning On… Coffee

Here’s what the science actually says.

 If a lawsuit currently being evaluated by a California court goes a certain way, coffee shops and coffee-selling gas stations may be forced post labels about potential cancer-causing chemicals.

They may even have to pay fines if they don’t warn customers about the risks of chemicals in coffee.

The Council for Education and Research on Toxics – the group behind the lawsuit – wants to penalise companies that don’t warn customers that coffee contains acrylamide, a chemical that California lists as one “known to cause cancer.”

Acrylamide naturally forms when plants and grains are cooked at high temperatures. It’s created in the process known as the maillard reaction, in which high heat transforms sugars and amino acids in ways that change flavour and tend to brown food. When potatoes, bread, biscuits, or coffee are heated, acrylamide forms.

But there’s no conclusive reason to believe that coffee or other foods expose humans to dangerous levels of acrylamide. And there’s no known way to make coffee without acrylamide.

Acrylamide and cancer risk

The chemical in question here was first discovered by Swedish scientists in 2002, according to the American Cancer Society.

Data suggests that in large quantities, acrylamide is carcinogenic to some animals. Animal studies have shown that putting acrylamide in drinking water can give rats and mice cancer.

 But the doses they consumed in those studies are 1,000 to 100,000 times the amount people get through their diet.

According to officials at the European Food Safety Authority, “it is likely that it has been present in food since cooking began,” since frying, baking, and roasting all create acrylamide. (This is the case for foods derived from plants including grains, however, not necessarily for meat or fish.)

Acrylamide does pose risks to humans, as industrial accidents when people have inhaled large quantities of it have shown.

It’s also one of the many chemicals produced in cigarette smoke, though in higher amounts than from making coffee or toast.

It’s important to remember that the dose of a chemical generally determines whether it’s harmful. Caffeine, which is also found in coffee, can be deadly at high doses – but that doesn’t mean all caffeine is bad.

And if you eat cooked food, acrylamide can’t be avoided. It’s present in about one-third of the calories the average US or European person consumes.

Humans also metabolise the chemical differently than animals do and so far, studies haven’t found any harmful connection between consumption of foods containing acrylamide and various common cancers.

If anything, most of the data that we have so far indicates that people who consume a lot of coffee have a lower risk for diseases including liver disease, heart disease, Type 2 diabetes, depression, and – especially important in this case – cancer.

 Health benefits of coffee

According to the evidence, drinking coffee isn’t unhealthy.

At least one major review of studies found that the more coffee people drink, the lower their risk for liver cirrhosis or liver cancer.

review of more than 200 studies found that people who drank three or four cups of coffee per day were 19 percent less likely to die from cardiovascular disease.

Heavy coffee drinkers have an 18 percent reduced risk for cancer overall, according to one large study, and some data indicates that coffee drinkers may be less likely to suffer from oral or pharyngeal cancer and advanced prostate cancer.

number of studies have also found that coffee drinkers are less likely to suffer from Alzheimer’s or dementia.

As far as the risks go, the International Agency for Research on Cancer has studied coffee and warned that extremely hot drinks may pose cancer risk if they burn the esophagus. But they have concluded that the drink itself is unlikely to cause certain cancers.

Most of the health benefits researchers have found have been in observational studies, meaning we don’t know that drinking coffee is responsible for the reductions in disease risk.

But in most of those cases, researchers have concluded that drinking coffee probably isn’t causing any harm.

Coffee May Cut Prostate Cancer Risk in Half

A recent study conducted in Italy—a country with a strong coffee-drinking culture—suggests that men who drink more than three cups a day have a lower risk for developing prostate cancer than those who don’t drink coffee. Overall, coffee and prostate cancer research has been divided and studies have produced mixed results.


For this study, researchers analyzed data from 6,989 men over the age of 50. As part of the study, the men reported their daily intake of Italian-style coffee. After about 4 years of follow-up, 100 new cases of prostate cancer were diagnosed in the study participants. According to researchers, men who drank at least three cups of coffee every day had a 53 percent lower risk of developing prostate cancer.

To learn more about the effects of coffee on prostate cancer, the researchers then combined extracts of caffeinated and decaffeinated coffee with prostate cancer cells in the laboratory. They discovered caffeinated coffee extract reduces the cancer cells’ ability to grow, divide, and spread—metastasize. Decaffeinated coffee extracts did not produce the same effect.


Coffee and Tea Benefits to Your Health

Drinking Coffee and Tea

Story at-a-glance

  • Coffee and tea are rich in beneficial antioxidants and other plant compounds that may boost your health
  • Benefits to heart health, brain health, weight loss, and chronic disease prevention have been established
  • For the best results, choose organic tea and coffee and drink it unsweetened without any milk or creamer

If you’re thirsty, pure water is always a good bet for a healthy beverage. But if you’re looking for a beverage to sip and savor while you start your day, take a work break, or relax in the evening, water doesn’t always hit the spot.

Fortunately, while there is no substitute for water (your body needs a healthy amount each and every day) there are other healthy beverages to choose from. Chief among those are coffee and tea, which should be good news to most of you, since these are among the most consumed beverages in the world.

Coffee has gotten a bad rap for health largely because 97 percent of it is sprayed with pesticides, and an artifact of optimizing for cost contaminates many of the beans with mycotoxins. Improper roasting is another area where toxins like acrylamide can creep in.

I am not saying this to justify my coffee addiction, because I do not enjoy the taste and have probably had less than five cups in my entire life, primarily to combat jet lag. To me the evidence is very clear: properly grown, harvested and roasted coffee can be very healthy.

Up to Five Cups of Coffee a Day Is OK – and Likely Good for You

In its recommendations for the 2015 edition of Dietary Guidelines for Americans, a government advisory committee, for the first time, said Americans could safely consume up to five cups of coffee a day, or approximately 400 milligrams (mg) of caffeine, with no detrimental effects.1

The recommendation was based on an evaluation of multiple meta-analyses and other studies evaluating the link between coffee and chronic diseases, including cancer, type 2 diabetes, heart disease, Parkinson’s, and Alzheimer’s.

While coffee has long gotten a bad rap because of its caffeine content, it also contains beneficial antioxidants, including significant amounts of hydrocinnamic acid and polyphenols.

In fact, because Americans drink so much of it, coffee is the number one source of antioxidants in the U.S. diet – with researchers noting “nothing else even comes close.”2 The antioxidants may even help neutralize the harsher effects of the caffeine that coffee naturally contains.3

Coffee May Be Good for Your Heart

It used to be said that coffee could increase your blood pressure, at least temporarily. But longer-term studies haven’t found a connection, and it’s now thought people may develop a tolerance to coffee’s hypertensive effects.4

On the other hand, increasing research suggests coffee may be quite good for your heart health. One meta-analysis that included data from 11 studies and nearly 480,000 people found drinking two to six cups of coffee a day was associated with a lower risk of stroke.5 That study noted:

The phenolic compounds in coffee possess antioxidant capacity and can inhibit the oxidative modification of low density lipoprotein cholesterol, thereby reducing the atherosclerotic process.

… [M]oderate coffee consumption (1 to 3 cups/day in the United States or 3 to 4 cups/day in Europe) was associated with a significantly lower risk of coronary heart disease in women… Ample evidence also indicates that coffee consumption is inversely associated with risk of type 2 diabetes, which is a risk factor for cardiovascular disease.”

Further, in a study of more than 25,000 people, those who drank a moderate amount of coffee – defined as three to five cups daily – were less likely to have calcium deposits in their coronary arteries than those who drank no coffee or more coffee daily.6

A large part of arterial plaque consists of calcium deposits (atherosclerosis), hence the term “hardening of the arteries.” Coronary artery calcium can be a significant predictor of future heart disease risk.

In addition, one study showed moderate coffee drinking reduces your chances of being hospitalized for heart rhythm problems.7 Another study found it may trigger a 30 percent increase in blood flow in your small blood vessels, which might take some strain off your heart.8

Coffee for Your Brain Health?

Coffee is renowned for its ability to make you feel more alert and focused, and boost cognitive performance, at least temporarily, but it also has some impressive benefits for brain health.

The chlorogenic acid (CGA) in coffee, for instance, protects neurons from glutamate neurotoxicity, which suggests it may have benefits for neurodegenerative diseases such as ischemic stroke.9

Drinking three to five cups of coffee a day in middle age has even been associated with a decreased risk of dementia and Alzheimer’s disease (by about 65 percent!) later in life.10

Caffeine also promotes production of the neurotransmitters serotonin, dopamine, and noradrenaline, and triggers the release of brain-derived neurotrophic factor (BDNF), which activates brain stem cells to convert into new neurons, thereby improving your brain health.

Among people with mild cognitive impairment (MCI), those with higher blood levels of caffeine (due to coffee consumption) were also less likely to progress to full-blown dementia.11 Caffeine/coffee intake is associated with a reduced risk of dementia or delayed onset, particularly for those who already have MCI,” the researchers said.

Coffee Might Fight Against Cancer, Too

Polyphenols in coffee, such as lignan phytoestrogens, flavonoids, and polyphenols are also known to have anti-cancer properties, as does caffeic acid, which inactivates several pathways involved in the development of tumors – including cell cycle regulation, inflammatory and stress response, and apoptosis.

In one recent study of people with advanced (stage III) colon cancer, drinking four or more cups of caffeinated coffee daily lowered the risk of cancer recurrence or death during the study by 52 percent compared to those who drank no coffee.

Drinking two or three cups per day was also beneficial, lowering the risk of recurrence or death by 31 percent.12

The researchers stressed that other caffeinated beverages, such as soda, did not have the same effect. No link was found between decaffeinated coffee and risk of colon cancer recurrence either.

Other research, a meta-analysis involving 59 studies, revealed an increase in consumption of one cup of coffee per day was associated with a 3 percent reduced risk of cancers.13 According to the researchers:

“Coffee drinking was associated with a reduced risk of bladder, breast, buccal and pharyngeal, colorectal, endometrial, esophageal, hepatocellular, leukemic, pancreatic, and prostate cancers.”14

There’s even research showing coffee consumption could lower your risk of skin cancer. Drinking four cups of caffeinated coffee daily might reduce your risk of melanoma, the most dangerous form of skin cancer.15

And one 2007 meta-analysis found an increase in consumption of two cups of coffee per day was associated with a 43 percent reduced risk of liver cancer16 – a finding that has been confirmed by more recent research.

More Reasons to Drink Coffee…

If you don’t drink coffee, there’s no reason to start up the habit for the sake of your health. There are many other ways to flood your diet with antioxidants – such as eating fresh vegetables and even cocoa.

However, if you’re already a coffee drinker you’ll be happy to know that coffee has also been linked to a lower risk of type 2 diabetes and a lower risk of obesity and metabolic syndrome.17 According to Harvard Medical School:18

Heavy coffee drinkers may be half as likely to get diabetes as light drinkers or nondrinkers. Coffee may contain ingredients that lower blood sugar. A coffee habit may also increase your resting metabolism rate, which could help keep diabetes at bay.”

Decaffeinated coffee seems to have less of a protective effect against diabetes than caffeinated coffee, likely because it lacks caffeine. As reported by the New York Times:19

One hypothesis is that caffeine increases the body’s sensitivity to insulin, so it requires less of the hormone. That, in turn, may reduce inflammation, which is a risk factor for diabetes and cancer.”

Research published in the New England Journal of Medicine has even shown that coffee consumption is inversely associated with premature death. The more coffee drank, the lower the risk of death became, including deaths from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections.20

5 Reasons to Have a Cup of Tea

It’s not only coffee that’s rich in antioxidants and provides a healthy addition to water for your beverage options. Tea ranks right up alongside coffee in terms of health benefits, so choose whichever you prefer (or drink both!). Although coffee is the most popular beverage in the US, tea takes the number one spot globally. As noted by the Epoch Times:21

Around the world, tea is the most common drink after water. Popularity increased in the 1800s because the practice of boiling water to make the tea meant water-borne pathogens like cholera and typhoid would be killed, making it safer to drink.”

Regardless of variety, black and green tea (as well as oolong, dark, and white teas) come from the same plant, an evergreen called Camellia sinensis. It is the processing method and degree of oxidization (exposure to oxygen) that creates the different tea types. While black tea is oxidized, green tea is not oxidized at all after the leaves are harvested. This minimal oxidation may help to keep the beneficial antioxidants in green tea intact, although both green and black teas have beneficial effects.

1.Rich in Antioxidants

Tea is rich in naturally occurring plant compounds called polyphenols, which can account for up to 30 percent of the dry leaf weight of tea, for instance. Within the group of polyphenols are flavonoids, which contain catechins. One of the most powerful catechins is epigallocatechin-3-gallate (EGCG), which has been shown to positively impact a number of illnesses and conditions. While green tea is a rich source of catechins, black tea is a rich source of tannins, which also have potent antioxidant properties.

2.Brain Health

Tea shows promise for protecting brain health. In a study presented at the 2015 International Conference on Alzheimer’s and Parkinson’s Diseases, those who drank green tea one to six days a week had less mental decline than those who didn’t drink it.22

Green tea also contains theanine, an amino acid that crosses the blood-brain barrier and has psychoactive properties. Theanine increases levels of gamma-aminobutyric acid (GABA), serotonin, dopamine, and alpha wave activity, and may reduce mental and physical stress and produce feelings of relaxation.23 Theanine may also help to prevent age-related memory decline24 and has been shown to affect areas of your brain involved in attention and complex problem-solving.25

3.Weight Loss

There is some evidence that long-term consumption of green tea catechins is beneficial for burning fat and may work with other chemicals to increase levels of fat oxidation and thermogenesis. In one meta-analysis, a mixture of catechin (tea and caffeine resulted in more fat break down than a placebo or caffeine only.26 People consuming catechins from green tea also lost nearly three pounds more, and were more likely to maintain the loss, than those not consuming them.27

Drinking coffee or tea before your meals may also help with weight loss simply because they help you to consume more water. Research shows drinking 16 ounces of water before a meal lost about nine pounds over a 12-week period, which was three more pounds than the group that didn’t drink water before meals.28 A cup of coffee or tea would certainly count toward this water requirement and may offer additional weight loss benefits as well.


Like coffee, drinking tea may help lower your risk of type 2 diabetes. One study found people who consume six or more cups of green tea daily had a 33 percent lower risk of developing type 2 diabetes than those who consumed less than one cup per week.29 A meta-analysis also revealed that drinking three cups (or more) of tea daily is associated with a lower risk of type 2 diabetes.30

5.Heart Health

Green tea improves both blood flow and the ability of arteries to relax, with research suggesting a few cups of green tea each day may help prevent heart disease.31 Study results also show EGCG can be helpful for the prevention of arterio­sclerosis, cerebral thrombus, heart attack, and stroke — in part due to its ability to relax your arteries and improve blood flow.32 In addition, as reported by the Epoch Times:33

“A Cochrane review evaluated 11 randomized controlled trials that ran for at least three months and were aimed at preventing heart disease in healthy adults or those at high risk of heart disease. Pooled results showed that both green tea and black tea significantly reduced blood pressure, with black tea lowering LDL-cholesterol and green tea lowering total cholesterol.”34

How to Make Your Tea Even Healthier…

To boost the benefits of green tea, add a squirt of lemon juice to your cup. Previous research has demonstrated that vitamin Csignificantly increases the amount of catechins available for your body to absorb. In fact, citrus juice increased available catechin levels by more than five times, causing 80 percent of tea’s catechins to remain bioavailable.35 On the other hand, while adding lemon juice is beneficial, adding milk is not. The proteins in milk may bind to and neutralize the antioxidants in tea, such that its health benefits are significantly reduced.36

And be aware that green tea plants are known to be especially effective at absorbing lead from the soil, which is then taken up into the plants’ leaves. Areas with excessive industrial pollution, such as China (where nearly 90 percent  of the world’s green tea is produced),37 may therefore contain substantial amounts of lead.38 Both black and green teas are also naturally high in fluoride, even if organically grown without pesticides.

This is because the plant readily absorbs fluoride thorough its root system, including naturally occurring fluoride in the soil. When selecting tea of any kind, it should preferably be organic (to avoid pesticides) and grown in a pristine environment because, as mentioned, tea is known to accumulate fluoride, heavy metals, and other toxins from soil and water. A clean growing environment is essential to producing a pure, high-quality tea.

The Healthiest Coffee Is Black and Organic

Just as you should avoid adding milk and sugar to your tea – and look for organic, high-quality sources – the healthiest form of coffee is organic and black. Remember, coffee beans are one of the most heavily pesticide-sprayed crops.and less than 3% is organic.  So, you should select only coffee beans that are certified organic. Ideally it’s also best to purchase fair traded coffee.

Some research suggests that adding dairy to your coffee may interfere with your body’s absorption of beneficial chlorogenic acids.39 Meanwhile, if you add sugar to your coffee you’ll spike your insulin levels, which contributes to insulin resistance.

Whenever possible, purchase sustainable “shade-grown” coffee as well to help prevent the continued destruction of our tropical rain forests and the birds that inhabit them. There are many who say shade-grown coffee tastes better as well. In addition, you’ll want to purchase whole-bean coffee that smells and tastes fresh, not stale; if your coffee does not have a pleasant aroma, it is likely rancid.

Grind it yourself to prevent rancidity, as pre-ground coffee may be rancid by the time you get it home. If you use a “drip” coffee maker, be sure to use non-bleached filters. The bright white ones are chlorine-bleached, and some of this chlorine will leach from the filter during the brewing process.

Bleached filters are also notoriously full of dangerous disinfection byproducts, such as dioxin. As mentioned, you needn’t start drinking coffee, or tea for that matter, if you don’t already. But if you enjoy it, feel free to indulge without guilt (and knowing your habit may be quite healthy, as long as you don’t take it to excess).

There is one caveat though pertaining to pregnant women, as caffeine can significantly impact the growing fetus. It is able to freely pass through the placenta, and since caffeine does not provide any benefits to your baby, only potential hazards, I strongly recommend pregnant women avoid ALL forms of caffeine.

Why Coffee Makes You Poop

If you feel the need to “go” after your morning joe, you’re among countless others who find that coffee stimulates your gut so much you always need to be close to a bathroom, no matter where you are. According to Today I Found Out, the “caffeine causes you to poop after drinking coffee” idea has been debunked — but there are still several physiological things in play that contribute to your needing to poop after a cuppa.

Bowel movements aside, many in the scientific community have claimed for decades that coffee actually provides multiple health benefits. Today, multiple studies and reviews report that coffee really does have benefits, and may even lower the risks of several types of cancer, heart disease, type 2 diabetes and neurological disorders.

So, whether you’re drinking it simply because you like it, or for perceived health benefits, it’s important to choose the most healthful coffee, just as you would with something you eat. From that point, the best brew is organic coffee, sans cream and sugar. If you do need something to color your coffee, a dollop of whole milk or heavy cream will work — and give you a slight taste of sweetness at the same time.

Avoid flavored coffees and creamers, as the thickeners and whiteners in them are often full of nutrient-suppressing chemicals such as dipotassium phosphate — which, incidentally, can cause diarrhea. Other whiteners may use high-fructose corn syrup and partially hydrogenated oils, aka trans fats, for flavor-enhancing. Sugar-free brands are no better: they are often laced with chemical-laden sucralose, aspartame or saccharine, all of which are not good for your body.
