In a recent issue of the Journal of Nutrition, an article was published showing a lower risk of mortality for coffee and tea drinkers over an 11-year average follow-up period.1
The study included 2,461 participants (over 40 years of age) and formed part of the Northern Manhattan Study. At baseline, the participants were free of stroke, cancer, and heart disease.
Researchers examined the association with food questionnaires during an 11-year follow-up. The majority of participants were coffee and tea drinkers, and the results were impressive.
A 7% reduction in mortality was seen for each additional cup of coffee ingested per day. Strong protection was seen in those who drank 4 or more cups of regular caffeinated coffee. Additionally, a 9% decreased risk of mortality was seen for each increased cup of tea per day.
The proposed beneficial mechanism is the high antioxidant content of these beverages, although the researchers concluded that more research is needed.
