Science has done a great job of providing us with the number of calories in food. It is useful information to have if you are trying to gain or lose weight, as the relation between weight and the number of calories consumed has been proved to be interlinked. When you eat fewer calories, you will lose weight and vice versa. Here you will find this valuable information for some of the most common foods, so that you can better plan your meals based on the caloric content. Keep in mind that recipes often add quite a few calories in the form of condiments and things like butter, milk, sugar, etc. so these need to be counted when planning your menu.
