Explanation:

A "portion" is how much food you choose to eat at one time, whether in a restaurant, from a package, or in your own kitchen. Versus a portion, a "serving" size is the amount of food listed on a product's Nutrition Facts. Sometimes, the portion size and serving size match; sometimes they do not.

Keep in mind that the serving size on the Nutrition Facts is not a recommended amount of food to eat. It is a quick way of letting you know the calories and nutrients in a certain amount of food.

Products made with refined sugar provide little nutrition. It is wise to limit these products.

BMIs above 25 are unhealthy and have been shown to increase the risk of certain chronic diseases. BMIs under 18.5 are considered "underweight."
