The main constituents of nutrition are protein, carbohydrate, fat, vitamins and minerals. All these constitute the elements of nutrition; however, their total quantity in a body depends on food choices. Food plays a very important role in nutrition because the nutritional value of food is directly related to its digestibility, nutrient density, and nutrient contents. A properly balanced diet provides all the essential nutrients required for a human body.

The food choices people make in their daily life affects their nutritional needs in many ways. One of the major influences of food choice is the portion size of the food. The nutrition quality of food can be improved by various methods. Two of the major methods are cooking and processing. Through processing foods are made available in smaller sizes and in different forms, thereby creating more variety in foods. The portion of food also determines its nutrient quantity and quality.

Another way of improving nutrition quality of food choices is eating frequently. Food intake should be increased gradually to obtain most of the nutrients that can be absorbed by the body in a short period of time. Sometimes people feel hungry quickly after consuming certain types of foods, in such cases a food combination can be adopted that contains all the nutrients required by the body for healthy living. Complemented with regular exercise, a balanced diet and regular sleep, a person’s nutrition and health are improved considerably.

In order to understand nutrition better, it is good to understand the role of photosynthesis in it. The action of photosynthesis is responsible for the production of food and other essential nutrients in plants. Autotrophic nutrition refers to the action of living things which provide energy in the form of food, through different types of cells such as prokaryotes and eukaryotes. This process of photosynthesis in plants is called photosynthesis. Different types of cells such as plant, animal, fungus, bacteria and human have different types of photosynthetic activity.

A good diet rich in proteins, vitamins, carbohydrates and fats is essential for good health. Some of the best foods for health and nutrition are beans, whole grain breads, fish, milk and cheese, vegetables, fruits, seeds, nuts, legumes and seaweeds. The consumption of these foods is essential to maintain good health. Nutritional needs of humans are fulfilled through a well-balanced diet that provides all the essential nutrients necessary by body needs.
