nutrition is defined as “The sum of the processes involved in eating‚ absorbing‚ and using nutrients”. The science of nutrition studies the processes by which the body uses food for energy‚ maintenance‚ and growth. It is particularly concerned with identifying those nutrients and substances in foods that foster the development of a strong body and promote good health. There are six major classes of nutrients they are; 1. Carbohydrates 2. Fats 3. Minerals 4. Protein 5. Vitamin 6. Water. Nutrition

Along with other minerals‚ vitamins are substances that a person can find in the food they eat. There are nutrients which are essential to the body‚ because all metabolic reactions in the organism happen thanks to their presence. One of the greatest things about vitamins is that they can be taken in both pill and liquid form. Experts in nutrition consider liquid vitamins to be a remarkable breakthrough in the domain. This is one of the reasons which may explain the lately outburst of liquid supplement

bodies of water receive excess nutrients that stimulate excessive plant growth. Eutrophication results from continuous pollution in the form of agricultural run-offs or sewage outflows. Fertilizers and sewage are both rich in nitrogen and phosphorus‚ which are both nutrients essential for plant growth. However‚ these nutrients are typically low in content in aquatic environments‚ which limits the growth of algae and plants‚ but with an increased amount of these nutrients‚ more plants are able to grow

Circulatory system is an organ system where nutrients pass through. Cardiovascular and lymphatic systems make up the complete circulatory system. Arteries‚ veins‚ and the heart are the main organs in the circulatory system. Examples of nutrients that are passed through are electrolytes‚ amino acids and lymph. Also other substances passed through the specific organ system are gases‚ hormones and blood cells to and from cells. The reason the substances are passed through the circulatory system is to

poor citizens turn to agriculture for feeding their families. Farmers use agricultural settlements and then cut down acres of land to use for agricultural farming. Once they have cut down the trees the farmers burn the stumps which releases certain nutrients that sustain the life of the crops which is called “Slash and Burn” agriculture. The problem with this type of

Many individuals eat only to fulfill their hunger‚ without consideration for the health or nutrient content contained within the foods he or she chooses. Scientist hypothesize that the human body remains in a recurrent hunger status‚ which is periodically satisfied by food intake. With this theory in mind it is easy to understand how over-eating

often used to describe the entire intestine. This article is primarily about the human gut‚ though the information about its processes is directly applicable to most placental mammals. The primary function of the small intestine is the absorption of nutrients and minerals found in food. (A major exception to this is cows; for information about digestion in cows and other similar mammals‚ see ruminants.) Size and divisions The average length of the small intestine in an adult human male is 6

Important qualities of foods now a day are calories‚ fat and carbohydrates while in the past they were vitamin B‚ protein and calcium. When producers take out all the unhealthy nutrients in food‚ the tastefulness of the food indeed goes down‚ making it a less desirable option. Once again‚ with the “important” qualities of food being limited and constraint to a strict standard‚ it is harder to combat the problem of finding healthy
