These are one of the main factors of increased risk of cardiovascular diseases. (1)
This study shows no association with
Diabetes
Diabetes and metabolic disorders are some of the main reasons for high mortality among populations. High caloric intake, high amounts of saturated fats, and refined sugars are the main reasons to increase risks of developing type 2 diabetes and metabolic syndrome. (2) Mars bar and snickers bar fit the category of high saturated fat and high sugar foods.
Cancer
