A new review study published in the Journal of the American Medical Association (JAMA), linked watching television for 2-3 hours per day with a higher risk of type 2 diabetes, cardiovascular disease and all-cause death.

“Beyond altering energy expenditure by displacing time spent on physical activities, TV viewing is associated with unhealthy eating (e.g., higher intake of fried foods, processed meat, and sugar-sweetened beverages and lower intake of fruits, vegetables, and whole grains) in both children and adults,” according to background information in the article.

“While the associations between time spent viewing TV and risk of type 2 diabetes and cardiovascular disease were linear, the risk of all-cause mortality appeared to increase with TV viewing duration of greater than 3 hours per day,” the authors write.
