All the above -while artery-clogging transfats capture many of the current headlines about healthier eating, it is also important to limit saturated fats for good heart health. for snacks, look for products that do not contain any trans fat and have 2-3 grams or less of saturated fat. look at the ingredients; if you see partially hydrogenated oil anywhere in the list, the product contains trans fat. since fat packs in more calories per gram than protein or carbohydrates, its important to keep the fat content of your snacks moderate(typically less than 10 grams of fat). that may seem like a lot of fat, but snacks like nuts or seeds are rich in healthy poly- and monounsaturated fats. plus, reducing the level of fat too much with snacks mightleave you feeling less than satisfied and searching for other munchies-and that defeats the purpose of the snack.
