Did you know...that eggs are a balanced source of fat? Of the 5 grams of fat in the yolk (there's none in the whites) 2 grams is mono-unsaturated, 2 grams is unsaturated fat and only 1 gram is saturated fat. We now know that fats are important in our diet, and that they must be balanced. And we know that mono-unsaturated fats (and polyunsaturated ones) are important to balance the intake of saturated fats. Eggs help satisfy that requirement. They also contain lecithin, another natural regulator of fats in the body.
