Abstract: Chicken eggs are provided which contain controlled amounts of vitamin E and iodine. No more than about 34% of the fatty acid content of the eggs comprises saturated fatty acid. The eggs may be eaten in the context of a standard low fat diet, without increasing the dieter's serum cholesterol concentration. The eggs are produced by maintaining egg laying chickens on a diet free of animal fat, wherein conventional feed is supplemented with controlled amounts of unsaturated fatty acid, iodine and vitamin E.
