Walnuts and Peanuts are good for health PART 1
After so many things said about health, I think we can deepen our knowledge in the field of diabetes, recalling that there is a antidiabetic hormone, glucagon-like peptide-1, secreted by the ileum, ie the second part of the small bowel. This hormone is secreted promptly after ingestion of carbohydrates and fats, leading to the increase of insulin release and the inhibition of glucagon secretions by pancreas. Antidiabetic hormone also acts on the stomach, reducing the gastric motility and acidic secretion.
Monounsaturated fatty acids that prevails in olives and avocado stimulates ileum cells which secrete this antidiabetic hormone, while saturated fatty acids, which are found in dairy products and meat, doesn’t have this effect. Replacing animal fats and polyunsaturated fatty acids in the diet with monounsaturated fatty acids can be a useful intervention to increase the secretion of this antidiabetic hormone, GLP-1, to patients with altered tolerance to glucose or type 2 diabetes.
Monounsaturated fatty acids improves the peripheral sensitivity towards insulin, ie decrease resistance toward insulin, lowers the blood pressure and are more resistant to lipid peroxidation. So, diabetics should get most of the energy from carbohydrates, rich in soluble fiber and monounsaturated fatty acid, CIS form. Without increasing the fiber intake, higher amount of carbohydrates can be harmful for the serum lipid profile, increasing triglycerides. Still related to diabetes, we recall that the palmitic acid, a saturated fatty acid, which represents the majority of animal fats, lowers beta cell proliferation that produce insulin, causing the death of these cells by apoptosis. Instead, palmitoleic acid, a vegetable monounsaturated fatty acid, has the opposite effects, leading to the proliferation of cells that produce insulin and counteracting the effect of palmitic toxic acid.
Walnuts offers a range of health benefits, being one of best sources of protein, essential fatty acids, vitamins and mineral substances.
The nutrients in nuts are found in a joint net superior to the products of animal origin. To the extent that it can, nuts should constitute a regular component of the diet. By the high concentration of fats and the by particularly high nutritional density, they provide a concentrated food, and at the same time, a relatively small calorie content.
For example, 100 g of walnuts contain about 15 grams of protein, 62-63 grams of fats, 10 to 11 g carbohydrates, 6 grams of fiber and about 2 g of minerals. Fat from nuts is made of linoleic acid, which represents 34%, the others fatty acids are in lower concentrations.
