Moderate coffee consumption extends lifespan

COFFEE has good and bad effects. Too much caffeine can cause several ailments – increase levels of uric acid, palpitations, hyperacidity, insomnia, etc.

Several studies, on the other hand, have proven the healthful benefits of coffee because of its antioxidants, including the reduce risk of endometrial cancer, and lowering the risk of tumor recurrence on Stage III colon cancer.

These benefits are for long-term moderate consumption of coffee.

A new study found that drinking coffee daily was associated with a lower risk of deaths from Type 2 diabetes, cardiovascular diseases, and neurological diseases in nonsmokers. Regular consumption of coffee can be included as part of a healthy, balanced diet. Again, this is for moderate drinking only.

“Bioactive compounds in coffee reduce insulin resistance and systematic inflammation,” said Ming Ding, M.D., the study’s first author and doctoral student at the Harvard T.H. Chan School of Public Health in Boston, Massachusetts. “They might be responsible for the inverse association between coffee and mortality. However, more studies are needed to investigate the biological mechanisms producing these effects.”

The findings are based on data from three large ongoing 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.
   
In general, people who frequently drank coffee were more likely to smoke and drink alcohol. To separate the effects of coffee from smoking, researchers repeated their analysis among non-smokers, and found that the protective benefits of coffee on deaths became even more evident.
   
The study was not designed to show a direct cause and effect relationship between coffee consumption and dying from illness. So the findings should be interpreted with caution, researchers said.
   
One potential drawback of the study design was that participants were asked to report how much coffee they drank, however researchers found the assessment to be reliable.

Previous studies found inconsistent associations between coffee drinking and risk of total and cause-specific death. This study adds to the literature that moderate coffee consumption may confer health benefits.
   
However, more research is needed to determine how coffee affects the body and whether different types of coffee may play a role. The National Institutes of Health funded the study. (ScienceDaily/American Hearth Association)
