Why are proteins important for the body?
A diet rich in proteins contribute to better glycemic control improves insulin sensitivity and creates a longer feeling of satiety.
Diet based on proteins (plant and animal origin) improves blood sugar control in people with diabetes, according to a study conducted by German scientists from the Institute of Nutrition at the University of Berlin. The study compared the effects of two types of diet with high animal protein content and high vegetable proteins with the same amount of calories. The study included 37 people with type 2 diabetes, with average age 65 years and the patients were divided into two groups. The patients menu in each group was composed of 40 % carbohydrates, 30 % fat and 30 % protein. Participants in the first group took the proteins of animal origin (meat, eggs, dairy products), while the other group took protein foods of vegetable origin (beans, nuts, soybeans, seeds …).
After six weeks of conducted testing, all participants had improvement in liver enzymes and steatosis (fat in the liver), and also a drop of glycosylated hemoglobin. Insulin sensitivity was increased only in the group which had consumed animal protein food, while the other group had noticeably improved kidney function. Recommended daily protein dose is from 0.8 to 1 g per kg body weight, which represents 15% to 20% of total daily energy intake. Patients with damaged kidneys, in consultation with doctors and nutritionists, must limit the intake of these nutrients.
- The main ingredients of proteins are amino acids, essential (which the human body does not generate and must be supplied through food) and nonessential (which the human body can create trough metabolism).
- Essential amino acids are predominantly in the animal products like meat, fish, eggs, milk, dairy products and in plant products like in legumes, grains, nuts, and soybean.
- Neither plant contains all essential amino acids. Therefore, if you do not eat meat, combine more types of products of plant origin product.
