What Are the Nutritional Value of Foods?

Food is any material eaten to provide nutrition to an organism. Food is generally of vegetable, animal, or fungi origin, and usually contains vital nutrients, including proteins, carbohydrates, vitamins, or other minerals. In modern diets, food is consumed in considerable quantities both to satisfy dietary requirements and to attain other ends, including preserving food and making available to the consuming public additional foods not normally found in their natural state. In a very broad sense, food may be classified according to the way it is eaten, and the method by which the nutrients are extracted from the food.


Health claims on food labels are designed to promote health through telling people what they can eat, how much of that food they can have, and what risks may be involved if they eat more of a certain food or if they eat a certain type of food. For example, some food manufacturers may label “low fat” or “no fat” and call their products low-fat or fat-free. The nutrition claims on food labels have to meet strict requirements established by the US FDA (Food and Drug Administration). They have to list all of the nutrients included in the food, whether or not they have been added in a manufacturing process, and how these nutrients contribute to the nutritional content of the product. Nutrient content information is also required to show the levels of each nutrient in order for the product to meet the maximum daily Allowable Amount (DLO), which is established by the federal government.

The food additives that manufacturers use to add color, flavor, or other sensations to food come under the class of synthetic ingredients. Examples include colors and preservatives used in junk food, flavored syrups, salt, sugar, artificial flavorings, saccharin and saccharine. Many of these additives are harmful to your health. Artificial flavorings cause allergic reactions, stomach ulcers, headaches, dizziness, nausea, and more. Salt is often added to foods to make them more salty, yet sodium is a needed nutrient.

One nutrient that you really need to eat enough of is vitamin A. This nutrient plays an important role in healthy eyesight and helps prevent many diseases called caries, which develop in the mouth and gastrointestinal tract. Caries can lead to tooth loss and even blindness. Vitamin A is found in carrots, cantaloupe, sweet potatoes, tomatoes, egg yolks, salmon, liver, milk, and fortified orange juice. In addition, you need to eat enough vitamin A for healthy skin and hair. If you are prone to osteoporosis, you should increase your vitamin A intake.

Some foods are animal products, such as eggs, milk, and meat. Animals living in nature receive a lot of nutrition from their diet. However, there is a difference between what the body needs as well as what the body wants. As an animal, the food you eat contains hormones, antibiotics, pesticides, hormones, fats, and other chemicals that enter into the blood stream through your food. These additives do nothing good for your body, so you should avoid them.

Milk is among the foods that you need to cut out of your diet if you want to reap the health benefits of a healthy diet. Milk is filled with calcium and vitamin D, which are good for the bones and teeth. Too much milk can cause indigestion, gas, bloating, diarrhea, headaches, and excessive flatulence. If you feel like you have had too much milk, try eating lean meats. Meat is high in protein and other nutrients that help strengthen the bones and teeth. When it comes to cutting back on some foods, fish is one of the easiest to give up because it contains so many detrimental toxins compared to other food groups.
