2 fruit and 3 vegetable servings: The key to a longer life?

Findings from a new observational study support most of the current dietary guidelines on fruits and vegetables.
Daily intake of 5 servings of fruits and vegetables was associated with a lower risk of death related to cancer, cardiovascular disease, or respiratory disease.
Starchy vegetables and fruit juices, however, did not appear to contribute to the reduction in risk.
For many decades, nutritionists have recommended a balanced diet to provide the body with the proper nutrients to stay healthy. The core components of this diet include vegetables, fruits, grains, proteins, and dairy.

Regular aspirin use at or after age 70 was associated with significantly reduced risk of colorectal cancer (CRC), but only in those who were already taking aspirin before turning 70, according to pooled data from two large cohorts of U.S. health professionals.
After adjustment for other risk factors, regular use was associated with a hazard ratio (HR) of 0.80 (95% CI 0.72-0.90) compared with non-regular use, reported Andrew T. Chan, MD, MPH, of Harvard Medical School and Massachusetts General Hospital in Boston.
As shown in their study online in
JAMA Oncology, this inverse association was evident, however, only among individuals who initiated aspirin use before age 70 (HR 0.80, 95% CI 0.67-0.95). Commencing use at or after 70 had no significant association with a lower risk of CRC (HR 0.92, 95% CI 0.76-1.11).
