Drinking More Coffee Leads To A Longer Life, Two Studies Say

Greater consumption of coffee could lead to a longer life, according to two new studies published Monday.

The findings have resurfaced the centuries-old conversation on coffee’s health effects.
One study surveyed more than 520,000 people in 10 European countries, making it the largest study to date on coffee and mortality, and found that drinking more coffee could significantly lower a person’s risk of mortality.

The second study was more novel, as it focused on non-white populations. After surveying over 185,000 African-Americans, Native Americans, Hawaiians, Japanese-Americans, Latinos and whites, the researchers found that coffee increases longevity across various races.

People who drank two to four cups a day had an 18% lower risk of death compared with people who did not drink coffee, according to the study. These findings are consistent with previous studies that had looked at majority white populations, said Veronica Wendy Setiawan, associate professor of preventative medicine at USC’s Keck School of Medicine, who led the study on nonwhite populations.

“Given these very diverse populations, all these people have different lifestyles. They have very different dietary habits and different susceptibilities – and we still find similar patterns,” Setiawan said.

The new study shows that there is a stronger biological possibility for the relationship between coffee and longevity and found that mortality was inversely related to coffee consumption for heart disease, cancer, respiratory disease, stroke, diabetes and kidney disease.

The study on European countries revealed an inverse association between coffee and liver disease, suicide in men, cancer in women, digestive diseases and circulatory diseases. Those who drank three or more cups a day had a lower risk for all-cause death than people who did not drink coffee.

Both studies were published in the Annals of Internal Medicine.

“We looked at multiple countries across Europe, where the way the population drinks coffee and prepares coffee is quite different,” said Marc Gunter, reader in cancer epidemiology and prevention at Imperial College’s School of Public Health in the UK, who co-authored the European study.

“The fact that we saw the same relationships in different countries is kind of the implication that its something about coffee rather than its something about the way that coffee is prepared or the way it’s drunk,” he said.

 

The biological benefits – and caveats

Coffee is a complex mixture of compounds, some of which have been revealed in laboratories to have biological effects, Gunter said.

Studies have shown that certain compounds have neuroprotective and anti-inflammatory properties that can help reduce risk for illnesses like Parkinson’s disease.

In the European study, people who were drinking coffee tended to have lower levels of inflammation, healthier lipid profiles and better glucose control compared with those who weren’t. It is still unclear which particular compounds provide health benefits, but Gunter said he would be interested in exploring this further.

Both studies separated smokers from nonsmokers, since smoking is known to reduce lifespan and is linked to various deceases. However, they found that coffee had inverse effects on mortality for smokers too.

“Smoking doesn’t seem to blunt the effects of coffee,” Gunter said. “It didn’t matter whether you smoked or not. There was still a potential beneficial effect of coffee on mortality.”

However, Dr. Alberto Ascherio, professor of Epidemiology and Nutrition at Harvard T.H. Chan School of Public Health, said people should be wary of this finding.

 

“Even if it was in some way true, it doesn’t make sense to me, because by smoking, you increase your mortality several-fold. Then, if you reduce it by 10% drinking coffee, give me a break,” said Ascherio, who was not involved in the study.

“I think it’s a dangerous proposition because it suggests that a smoker can counteract the effects of smoking by drinking coffee, which is borderline insane.”

The studies complement work that has been done on coffee and mortality, he said, and it has been reasonably documented that coffee drinkers have a lower risk of death.

With all observations from previous studies, however, it’s difficult to exclude the possibility that coffee drinkers are just healthier to begin with, Gunter said.

People who avoid coffee, particularly in places like the US and Europe where drinking the beverage is very common, may do so because they have health problems. Their higher mortality rate could be a result of them being less healthy to begin with.

“I think that the solid conclusion is that if you’re a coffee drinker, keep drinking your coffee and be happy,” Ascherio said. And if you’re not? “I think you can go on drinking your tea or water without a problem.”

Meanwhile, Gunter and Setiawan stand a bit more firmly on coffee as a health benefit.
“The takeaway message would be that drinking a couple cups of coffee a day doesn’t do you any harm, and actually, it might be doing you some good,” he said.

“Moderate coffee consumption can be incorporated into a healthy diet and lifestyle,” Setiawan said. “This studies and the previous studies suggest that for a majority of people, there’s no long term harm from drinking coffee.”

Coffee vs. Tea: Is One Better for Your Health?

A hot cup of coffee can perk you up in the morning. A soothing cup of tea can help you relax after a stressful day. And the latest research about the health benefits of each might help you feel a little better about them, whichever beverage you drink.

After years of studies that seemed to swing between dire warnings and cheery promises about what our favorite caffeinated beverages do and don’t do, much of the recent science regarding coffee and tea is generally positive.

The WHO’s International Agency for Research on Cancer recently took coffee off its list of suspected carcinogens, and some research suggests it could help keep colon cancer from coming back after treatment. Other studies suggest drinking coffee might stave off Alzheimer’s and Parkinson’s diseases.

Various studies have pointed to tea drinkers having lower odds of skin, breast, and prostate cancers. Researchers are still trying to pinpoint the exact ways that happens. But tea, particularly green tea, is rich in compounds like antioxidants, which can limit cell damage and boost the immune system; and polyphenols, which have been shown to lower blood pressure and cholesterol. It also may help stave off Alzheimer’s disease through a polyphenol known as EGCG, which prevents the formation of plaques that are linked to that brain-damaging illness.

Is one better for you than the other?

Experts say that’s hard to say. That’s because it’s difficult to separate out their different ingredients, their role in your diet, and their effects on different body systems.

“I think people are looking at both coffee and tea and how they affect everything, including cancer and GI disease and cardiovascular diseases,” says Elliott Miller, MD, a critical care medicine specialist at the National Institutes of Health.

Miller and his colleagues recently looked at signs of heart disease in more than 6,800 people from different backgrounds across the country. About 75% drank coffee, while about 40% reported drinking tea. Drinking more than one cup of tea regularly was linked to less buildup of calcium in arteries that supply blood to the heart, a development that can lead to heart disease.

Coffee didn’t have an effect either way on heart disease, but that was significant in itself, Miller says.

“Very often patients will ask their doctors, ‘Hey, doc, I’ve got coronary artery disease, or I’ve got risk factors like high blood pressure or cholesterol. Is it safe for me to drink coffee?’ Because everyone thinks drinking coffee makes your heart excited and is potentially bad,” Miller says. “So finding that it’s neutral, I think, is pretty important.”

Researchers say it’s hard to pinpoint exactly how both drinks affect health. Both coffee and tea are “complex beverages” that contain a variety of ingredients. They include caffeine, polyphenols, and antioxidants – compounds researchers are studying for their potential cancer-fighting properties, says Lisa Cimperman, a clinical dietitian at University Hospitals Case Medical Center.

“It’s more of a dynamic interaction than one single compound,” Cimperman says. Some people have tried to isolate one element in tea or coffee that they think is the secret to one effect or another, “and then they realize that it doesn’t have the same effect.”

Cimperman said drinking tea has been linked to lower risks of cancer and heart disease, improved weight loss, and a stronger immune system. Meanwhile, studies point to coffee as a potential way to head off not just Parkinson’s but type 2 diabetes, liver disease, and heart problems, Cimperman says.

Another recent study, led by Charles Fuchs, MD, director of the Gastrointestinal Cancer Center at Boston’s Dana-Farber Cancer Institute, found regular coffee drinking may help prevent colon cancer from coming back after treatment.

In his study of nearly 1,000 patients, Fuchs says, there was a “significant and linear” association between drinking coffee and lower risk of colon cancer returning in those who drank four or more cups a day. “The more coffee they drank, the lower risk of recurrence.” But the researchers aren’t clear on which element of the drink contributed to that result, and there didn’t seem to be any effect from drinking tea, he says.

“I think you can have two or more cups a day without any concern, and certainly that may benefit you,” Fuchs says. But what about for those who don’t drink coffee? “If it was somebody who hates the stuff and asks, ‘Should I drink it?’ I’d say no. I’d counsel them about diet and exercise and avoiding obesity as measures I think would have a similar benefit.”

Other researchers are asking questions about what role genetics and lifestyle play into the effects of drinking coffee or tea. For instance, coffee and cigarettes once went together like … well, like coffee and cigarettes, which cause cancer and heart disease.

Some people’s bodies process coffee differently than others, says Martha Gulati, MD, head of cardiology at the University of Arizona College of Medicine in Phoenix. Meanwhile, a preference for tea over coffee might reflect other healthier behaviors, she says.

“Does someone who drinks tea do yoga or meditation more?” Gulati says. “I’m not necessarily saying they’re associated, but do they exercise more? Are they drinking things like green tea to maintain their weight better than other types of drinks?”

And Robert Eckel, MD, an endocrinologist at the University of Denver, says an overall heart-healthy diet is “probably the most important aspect” of preventing heart disease.

“We’re talking about fruits and vegetables, whole grains, lean poultry, fish, legumes, nuts, and avoiding saturated fat. That nutritional message is unchanging,” Eckel says.

There are other variables. The WHO’s ruling on coffee nonetheless cautioned that any kind of extremely hot drinks could raise the risk of esophageal cancer, while Cimperman says dumping a lot of cream and sugar into your drink can blunt any benefits.

“No one beverage or food will make or break your diet,” she says. “The quality of your diet is always the sum of all the parts.”

The Dangers of Using K-Cups for Your Morning Cup of Joe

You might want to stick with your traditional coffee machine.

BY MACAELA MACKENZIE    February 24, 2016  Women’s Health

Opinions on having a morning cup of joe from a disposable coffee pod tend to be pretty divisive—you either love K-Cups or hate ‘em. But as of this week, personal opinions no longer matter for residents of one German city.

Hamburg has officially banned all coffee pods (including K-Cups) from government buildings, citing their negative environmental impact, according to CNN. But is your Keurig brew really that bad? Well, kinda.

Here are four real concerns about getting your caffeine fix from a coffee pod.

1. They Produce a Ton of Waste
Those little cups may not seem like a big deal, but think about how often you have to empty the Keurig bin at the office—those babies pile up fast. For every six grams of coffee, you’re looking at about three grams of waste—much less efficient than sticking with a more traditional brew. To put it in perspective, in 2014 Mother Jones estimated that we disposed of enough K-Cups to wrap around the world 10.5 times. Damn.

2. They Aren’t Biodegradable
Since they contain more than one type of material, K-Cups are extremely difficult to recycle. In an effort to be more eco-friendly, Keurig has promised to make their cups recyclable—but not until 2020. Until then, you’ll have to separate the aluminum top from the plastic cup yourself and then find a special recycling service.

3. They Contain Aluminum
The fact that K-Cups contain aluminum is also not great for the environment. Even if all that aluminum doesn’t end up in a landfill (and that can pile up with some serious speed), recycling aluminum produces some toxic byproducts that have to be buried in a landfill anyway. Not a problem you have to deal with if you’re using an old-fashioned coffee filter.

4. They Could Pose a Hazard to Your Health
K-Cups have been confirmed to be BPA-free and made of “safe” plastic, but some studies show that even this type of material can have harmful effects when heated. When you come into contact with these plastic chemicals, they can act like estrogen in your body, throwing your hormones out of whack.

The Drink That Fights Depression

Sip this to stave off sadness

By AMANDA FIRST    MARCH 26, 2013

If you’re a java junkie—you drink 4 or more cups of coffee a day—you’re about 10% less likely to be depressed than someone who has never stepped inside a Starbucks, says a new study from the National Institutes of Health and AARP. (Good news: Other studies suggest that just 2 or 3 cups of coffee a day may be enough to perk you up.)

Coffee’s benefits may not be due solely to its caffeine high, because depression protection doesn’t extend to all caffeinated drinks. (Cola was among the many sweetened beverages linked to a higher risk of depression, and drinks with artificial sweeteners were even more strongly linked.)

Coffee’s mood-lifting effect might be traced to its antioxidants, says lead researcher Honglei Chen, PhD, an epidemiologist at the National Institute of Environmental Health Sciences. So drink up: There’s also research that indicates regular coffee consumption delays the onset of Alzheimer’s disease and protects against type 2 diabetes.

“Cup of joe” found to have more health benefits

Published on May 7, 2007 

According to a new study drinking coffee may offer protection from type 2 diabetes and some types of cancer.

These latest findings also suggest that the antioxidants present in coffee can also lower the risk of heart disease and cirrhosis of the liver.

Coffee contains hundreds of components including substantial amounts of chlorogenic acid, caffeine, magnesium, potassium, vitamin B3, trigonelline and lignans.

Chlorogenic acid has been shown in animal experiments to reduce glucose concentrations; coffee also contains tannin, which is beneficial for heart and arteries.

Researcher Dr. Rob van Dam of the Harvard School of Public Health, says that coffee, if taken in moderate amounts, can actually prevent colon, liver and rectal cancer.

Other experts also believe that coffee reduces the amount of cholesterol, bile acid and natural sterol secretion in the colon which accelerates the passage of stools through the colon and cuts down the exposure of the lining of the intestine to potential carcinogens in food.

Recent research in Norway has found that people who drank four to six cups of coffee a day had a 28 percent reduced risk compared with people who drank two or fewer.

They also found that women who drank one to three cups a day reduced their risk of cardiovascular disease by 24 percent compared with those drinking no coffee at all.

It is also suggested that coffee contains more antioxidants than a serving of grape juice, blueberries, raspberries and oranges.

Coffee is one of the most widely consumed beverages in the world, and experts say the volume of scientific evidence suggests that moderate coffee consumption may halve the risk of certain disease conditions, such as Parkinson’s disease, reduce the risk of Alzheimer’s disease, kidney stones, gallstones, depression and even suicide.

In other research Dr. Lenore Arab, a nutritional epidemiologist at the David Geffen School of Medicine at UCLA, reviewed the latest epidemiologic literature on cancers and coffee.

Dr. Arab found almost 400 studies on the association between coffee consumption and cancers at various sites.

Dr. Arab says the evidence suggests there are two areas where there is some evidence of increased risk: leukemia and stomach cancer.

Experts do however warn that excess coffee intake is also linked to increased nervousness, rapid heartbeat and trembling hands.

Future research may well lead to the development or selection of coffee types with improved health effects.

The Amount of Coffee That Protects Against Dementia Precursor

How coffee intake affects the chance of developing mild cognitive impairment.

Drinking one or two cups of coffee a day can protect the brain against a precursor to dementia, a new study finds.

More coffee, though, does not lead to a higher neuro-protective effect.

In fact, the study found that people who increased their consumption by a cup or two had twice the risk of mild cognitive impairment (MCI).

MCI is a common precursor to developing forms of dementia, like Alzheimer’s disease.

Symptoms of MCI include minor memory problems and slowed thinking and judgement.

coffee

The Italian study of 1,445 people also found that people not drinking coffee were at higher risk than those who drank moderate amounts.

The study’s authors write:

“These findings from the Italian Longitudinal Study on Aging suggested that cognitively normal older individuals who never or rarely consumed coffee and those who increased their coffee consumption habits had a higher risk of developing MCI.
Therefore, moderate and regular coffee consumption may have neuroprotective effects also against MCI confirming previous studies on the long-term protective effects of coffee, tea, or caffeine consumption and plasma levels of caffeine against cognitive decline and dementia,”

Participants in the study were aged 65 to 84-years-old.

They were followed up over an average of 3.5 years to see if they had developed any thinking problems.

The study was published in the Journal of Alzheimer’s Disease (Solfrizzi et al., 2015).
