You may think of pigs as lazy and gluttonous. But these pigs work out and they are being used to study diabetes.
Pigs can get diabetes just like humans. It usually happens because of their couch-potato lifestyle and diet.
They eat high fat, high cholesterol food, and get little exercise. But a recent study put a group of diabetic pigs in the gym for five months.
Not only did their bodies get lean and muscular, their arteries showed a decreased risk for coronary disease.
