Oh, butter. It's so tasty, yet so dangerous. Children do need fat while they're growing, but butter isn't exactly the best source. While it's fine in small amounts, such as a pat on whole-grain toast, too much butter will increase your child's intake of saturated fat. Instead of cutting it out completely, why not fake buttery goodness with flaxseed oil? It's got about one-seventh the saturated fat of butter. On top of that, flaxseed oil is low in cholesterol and sodium and high in omega-3 fatty acids, which help promote cognitive functions and healing. Substitute it wherever you would use butter, such as a topping on popcorn or mashed potatoes. Just be careful not to go overboard -- flaxseed oil still has just as many calories as butter does, so about a tablespoon a day is a good limit.
