Plant-based diets may reduce risk of type 2 diabetes
In one of the largest, long-term diet studies, 200,727 men and women who were healthy at the beginning reported their diets every two to four years over a 25-year follow-up period. Doctors classified foods according to plant or animal source, and gave each a positive or negative index score. Whole grains, fruits, vegetables, nuts, and legumes were positive, while fruit juices, sweetened beverages, refined grains, potatoes, and desserts were negative. Animal foods including fats, dairy, eggs, fish, seafood, meat, and poultry also got a negative index rating. Overall, those who consumed a diet emphasizing plant-based foods and de-emphasizing animal-based foods were 20 percent less likely to develop type 2 diabetes. In an interesting finding, people whose diets focused on low quality plant-based foods, such as sweetened beverages, saw chances for type 2 diabetes increase.
