The physical features of various species depend on the type of food consumed. Herbivores have several stomachs, which allows them to digest vegetable food. Their teeth and jaws are adapted to crushes greenery. However, carnivorous animals have acute fangs, enabling meat tearing, And they are built like this, so that they can move quickly and fight effectively. Man is omnivorous creature. Has teeth, which allows him to crush and meat, and plants. If it goes on a vegetarian diet, He must take care of it, that the plants made up of it contain a sufficient amount of nutrients, proteins and vitamins and fully replaced the food of animal origin.
Minerals
They play a big role in human nutrition by regulating metabolism and providing building material for the skeletal system. They also accelerate wound healing. Mineral compound deficiency can cause muscle spasms and convulsions. If you don't eat meat, The diet must contain various vegetable dishes, nuts and fruits, To provide the body with the right amount of minerals, Especially iron. Also rich in protein fungi and seaweed contain valuable minerals.
Fats
They are a valuable source of energy, as well as a building component enabling cell regeneration. High energy content makes, that after eating a dish containing a lot of fats, we feel saturated. Remember, that large amounts of water are needed in the process of fat digestion. Therefore, you should avoid eating fatty dishes then, when there is a lack of drinking water. Extremely rich in fats, as well as in protein there are nuts.
Fiber
Fiber, that is, the body not absorbed by the body; Facilitates intestinal work and digestion and regulates the excretion of food residues. Vegetables are rich in fiber, fruit and some species of bread.
Carbohydrates
Otherwise sugars, play a basic role in nutrition providing the body with energy. They can be complex sugars, unsettled, such as starch, or simple and sweet, For example, sucrose and glucose. Complex sugars taken with food are processed to the simplest form – glucose and storage in the liver, and then made available to the body, when there is an energy demand. Unnecessary glucose, not processed into energy, is turned into fat. Honey is a great source of sugar.
Vitamins
Control tissue growth and regeneration, They also take part as biocatalizers in reactions stimulating energy production. The best source of vitamins are fresh fruit, but like most food of plant origin, they are only available at certain times of the year. In situations, When we are only on our own strength for a long time and we have to survive for many months in countries with a moderate climate, The fruit should be collected in the right time and stored accordingly for the winter.
Protein
The most important building ingredient; enables the body's growth and tissue regeneration. Certain proteins must be supplied in the form of food, so that the body and receives an extremely important amino acid for its functioning, which he cannot produce himself. Meat and fish are a rich source of all necessary amino acids, as well as many vitamins and minerals. Some proteins also occur in vegetables and fruits.
