What is Nutrition?
Nutrition is the study of all the intercommunication that occurs between people and food. It includes the understanding which nutrients we need, where to find them in food, how they are used by our bodies and the result they have on our health. We do not eat specific nutrient, we eat food and we choose the right amount of combination of foods and thus our diet provides all the nutrients we need to stay healthy and if we choose a poor amount of food in our body the essential nutrients will be missing in our body but however to maintain the right nutrients it can be very challenging and difficult because we eat for many other reasons but we do not eat thinking that we need nutrients to maintain a good diet.
Nutrients are necessary for human bodies to maintain energy to move, and generate chemical substances such as enzymes for metabolic activities. The nutrients that are essential to human bodies may be categorized into three types. The first category includes carbohydrates, fats, and proteins. They are the primary source of energy. Carbohydrates are the principal dietary source of energy. Fats supply energy and essential fatty acids, and they help absorb the fat-soluble vitamins. However, some kinds of fat, especially saturated fats, increase the risk for coronary heart disease by raising the blood cholesterol. Proteins are polymers of amino acids that are needed for synthesis of body proteins in muscle, organs, bone and skin, and for synthesis of enzymes, certain hormones, antibodies and a host of specialized products (Human amino acid requirements: can the controversy be resolved).
Macronutrients & Micronutrients
Carbohydrates, proteins, and fats are called macronutrients because they’re large, and energy nutrients because they provide the fuel your body need to do things.
Vitamins and minerals are called micronutrients because they’re much smaller in comparison. That doesn’t mean they’re less important; they’re still essential nutrients, but you only need little bits.
Micronutrients can be classified by whether they’re soluble in fat or soluble in water. Vitamins A, D, E, and K are fat-soluble, and the B-complex vitamins and vitamin C are water-soluble. Minerals are grouped as major minerals or trace minerals, depending upon how much of each mineral is necessary.
