Food labels are generally used by any company that produces food products especially in cans or boxes and there are different types of food labels. Every one of them, however, is made to give nutritional information regarding the types of food they contain and the nutritional values of these foods as well. These are important because of the fact that they are required to do this by law and apart from this, they have to include this information for patients who are, for example, diabetics or cancer patients. Different types of food labels are made different but they all serve the same purpose.
The first of the many types of food labels are Nutritional Facts Label which, as the name suggests, is to be put on to the package of food that is in a box, can or package of any sort. Since one cannot open the package without having to buy it, these types of food labels give a good idea as to what the packet consists of and the nutritional facts and calorie count of the food too. They typically also consist of information about carbohydrates, proteins, fats, calories, trans-fats and they inform you of the fact that the food has been made based on a 2000 calories diet.
Certain types of food labels are used for raw foods. You will often see in a store or mall that packaged foods (chicken, fish, pork, beef, fruits, vegetables and veal) have nutritional labels on them that tell the reader about the weight of the product, the number of calories, proteins, carbohydrates and fats in them. One need not put them all the time but often producers do so because these labels give buyers a good idea of what they are buying.
In some cases the FDA may require companies to use various types of food labels. Also, another reason due to which various types of food labels are put on to products is because certain people who are into fitness would like to know what is going into their bodies. They always check the food label so that they know what is going into their bodies and if they feel that the food is too high in calories or carbohydrates, for example, they may choose to go for an alternative product instead. This way they are able to keep themselves well informed and eat according to their requirements as well.
Various types of food labels are viewed by different people for different reasons. Sometimes people with certain nutritional deficiencies need to ensure that they are taking vitamins from the right foods in the right amounts, for example. Or a person with fat deposits on the liver would need to check out the fat content before he/she can buy it for himself/herself. Other people may not be allowed to have more than one serving of certain foods and these types of food labels help them keep a check on what they are eating and on the amounts of food that they eat too.
