Arteries carry blood away from the heart, and veins carry blood toward the heart. Capillaries connect the arteries to the veins throughout the body. Fun Fact: If all the blood vessels from a child's size body were lined up in a row, they would form a line more than 60,000 miles long.
Fats in Butter. Butter is about 80% fat, and the rest is mostly water. Basically, it is the fatty portion of milk that has been isolated from the protein and carbs. Butter is one of the most complex of all dietary fats, containing more than 400 different fatty acids. It is very high in saturated (about 70%) fatty acids, and contains a fair amount of monounsaturated fatty acids (about 25%).
Saturated fat is not as healthy, but it is okay in balance with other fats. A tablespoon of butter is pretty much like a tablespoon of any fat â it contains around 14 grams of fat and, of this, about 8 grams is saturated fat. Thereâs only 30 mg of cholesterol. Because the recommendations for a healthy diet are to keep saturated fat to around 20 grams, using butter can add up the fat grams fast.
