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%).
Itâs no surprise that there are loads of âbetter than butterâ products in superÂ­markets today. Butter, after all, has 100 calories, 11 grams of fat, and 7 grams of saturated fat per tablespoon (about half the saturated fat you should consume in a day if youâre following a 2,000-calorie-per-day diet).Margarine has the same calorie and fat content as butter, but less saturated fat.nd all spreadsâeven those made with olive oil (such as Olivio) or yogurt (Brummel & Brown)âhave trans or saturated fat. Our tasters liked Brummel & Brown 35% Vegetable Oil Spread (which contains partially hydrogenated soybean oil) and I Canât Believe Itâs Not Butter Light (which has palm and palm kernel oils).
