Heinz Catsup leaves the bottle at 25 miles per year. The only food that does not spoil is honey. The Fullness Factor Researchers at the University of Sydney devised a Satiety Index based on how full volunteers felt after eating 240 calories worth of various foods. Calorie for calorie, bulky high-fiber foods such as fruits and vegetables rated high. High-fat foods ranked low, since 240 calories' worth is a small portion.
Potatoes rank highest, seven times higher than the least-filling food, croissants.
Oranges and apples outscore bananas. Fish is more satisfying, per calorie, than lean beef or chicken. Popcorn is twice as filling as a candy bar or peanuts. Broccoli is a good source of calcium. A 1997 study found that this calcium is absorbed as well by the body as that in milk.
