Study finds connection between coffee consumption and longevity


Those who need that bittersweet daily dose of coffee to start their day will feel uplifted after reading about a new study conducted by Stanford University's School of Medicine on the benefits that can be reaped from regular caffeine consumption.

Published on Stanford Medicine News Center on Monday, the study found a link between coffee drinkers and a lower risk of inflammation-related diseases.

Leading author David Furman, PhD explains in a release that more than 90 per cent of all non-communicable diseases of aging, such as "cancers, Alzheimer's disease and other dementias, cardiovascular disease, osteoarthritis and even depression", are associated with chronic inflammation.

9 health benefits of coffee

  • Coffee contains caffeine, and caffeine is one of the few substances that has been found to speed up fat burn, especially in younger and leaner people. Studies have shown coffee to be able to spike metabolism rate by 3 -11%. To enjoy the calorie burn, skip the latte and go for black coffee. Cut out the sugar and milk to avoid unnecessary calories.
  • Ever downed coffee shortly before exercising? You would have felt a surge in energy and focus, leading to an improvement in speed, agility, strength, endurance, reaction time et. cetera, thanks to caffeine activating certain parts of your brain and nervous system. All critical to running faster, nailing a shot, or finishing bootcamp class in good shape.
  • Who knew that your daily cup of joe could help fight a chronic disease like diabetes? Several studies, including one in the journal Diabetologia, found that drinking at least three cups of coffee a day may reduce the risk of getting Type 2 Diabetes by up to 50%. Coffee contains many compounds that are known to reduce insulin resistance.
  • A study in the Journal of Alzheimer's Disease found caffeine to be particularly useful in protecting against mental health diseases like Alzheimer's and dementia. When middle-aged coffee drinkers had three to five cups a day, their risk of dementia and Alzheimer's disease dropped by about 65% later in life. Other studies have also shown a similar preventive effect for Parkinson's disease.
  • Coffee contains a particular ingredient that helps to prevent alcoholic cirrhosis (long-term liver damage from alcohol) by up to 80%, according to a study in the Archives of Internal Medicine. The effect was most pronounced in those who drank large quantities of alcohol.
  • Having four or more cups of coffee a day cuts your risk of depression by about 20%, says Harvard School of Public Health research. Caveat: The coffee has to be caffeinated. Drinking decaf, tea, soft drinks, chocolate and other beverages containing less caffeine doesn't produce the same effect. Now coffee is really your happy pill! (Photo: StockUnlimited)
  • It should come as no surprise that coffee has cancer-fighting properties, since coffee is loaded with antioxidants. In particular, coffee can slash your risk of liver cancer by about 40% if you increase your consumption by two cups a day, according to research in Gastroenterology journal. Coffee has also been linked to a lower risk of colorectal cancer in other studies.
  • A recent study published in the journal Stroke found that those who drank at least one cup of coffee a day had a reduced risk of stroke and heart disease. However, that benefit is negated for those who had seven or more cups of coffee a day, or if they were smokers. The bottomline: Leading an active, balanced lifestyle is still the key to staying healthy.
  • In a large-scale study that examined the relationship between coffee and risk of mortality, it was found that drinking one to five cups of coffee a day reduced the likelihood of death among more than 200,000 men and women. Researchers are unable to pinpoint the exact reasons, but they note that coffee contains many compounds that help to lower insulin resistance as well as inflammation levels in the body. of getting Type 2 Diabetes by up to 50%. Coffee contains many compounds that are known to reduce insulin resistance.

"It's also well-known that caffeine intake is associated with longevity," he said. "Many studies have shown this association. We've found a possible reason for why this may be so."

The study examined blood samples of 100 people and concluded that older people with lower levels of inflammation were all regular coffee drinkers.

The metabolic substances within caffeine is proven to counter the actions of nucleic-acid metabolites-the molecules that form our genes-which circulate the blood and can trigger this inflammatory process.

Contributing researcher Mark Davis, PhD stated, "that something many people drink-and actually like to drink-might have a direct benefit, came as a surprise to us," adding that the study did not demonstrate a causal link.

"We didn't give some of the mice coffee and the others decaf. What we've shown is a correlation between caffeine consumption and longevity. And we've shown more rigorously, in laboratory tests, a very plausible mechanism for why this might be so."
