Healthy diet linked to lowered risk of heart disease, stroke, cancer or other disease

healthyeatingA new study, published in the journal of PLOS medicine, has demonstrated that the risk of dying from , stroke, cancer or other diseases among low income individuals can be lowered by sticking to a . The participants consisted of 84,735 adults, aged 40-79, recruited from 2002- 2009. Two-thirds of the participants were African-American.

Of the 77,572 participants, 6,906 participants died which included 2,244 from , 1,794 from cancer and 2,550 from other diseases. After controlling for factors such as age, weight, exercise, smoking and prior history of some chronic diseases, the investigators found that participants who ate the healthiest diet had an approximately 20 percent lower risk of death from those diseases than those with the least . The participants were followed on an average for 6 years.

Participants completed frequent food frequency which analyzed the types and amounts of foods in their usual diet. The investigators used the federal government’s Dietary Guidelines for Americans (DGA), and the Healthy Eating Index (HEI) to assess the healthfulness of the participants’ diets. The DGA emphasizes a diet rich in vegetables, fruits, whole , seafood, legumes and nuts; moderate in low- or non-fat dairy and alcohol; and low in red and processed meats, sugar-sweetened foods and drinks and refined

“This is the first study to our knowledge reporting this association in a low-income population that largely comprises African-Americans,” said Wei Zheng, M.D., Ph.D., MPH, director of the Vanderbilt Epidemiology Center and chief of the Division of Epidemiology. “These findings present direct evidence that dietary modification may influence disease prevention in this underserved population.”
