Nutrition

To maintain a healthy body we need to feed properly. The body needs nutrients in adequate quantities to be able to function at full capacity.
Due to the fact that the human body cannot produce the necessary amount of nutrients on its own, we need to get them from food. More information about the needed amount of carbohydrates, proteins and lipids can be found in specialized literature.
Carbohydrates are the main source of energy. There are 3 types of carbohydrates (starch, sugars and fiber) and can be found in foods of plant origin: cereals, vegetables, fruits, etc. Carbohydrates provide for 4,1kcal/1HC.

Proteins have a very important role in the development and proper functioning of the body. They are part of the composition of various tissues, enzymes and hormones. Based on the proportion of the all nine amino acids essential to the dietary needs of humans , proteins are classified in 3 main categories: whole proteins (contain the adequate proportion), partially complete proteins and incomplete proteins (may have all the necessary number of amino acids but not the correct proportions for sustaining all the biological functions of the human body).
The main sources of proteins are foods of animal origin because they give us the proteins best absorbed by our bodies. 1g of proteins gives us 4.1kcal.

Lipids are a very good source of energy because 1g of lipids gives us 9.3kcal. There are saturated and unsaturated lipids. If we eat process foods often, we need to pay attention to the saturated lipids because they get glued to our artheries and so, could trigger various heart diseases. Processed foods contain high quantities of saturated lipids.
The lipids most beneficial for the human body are the unsaturated ones. We can choose from monounsaturated fats (nuts, avocado, oils) and polyunsaturated fats (fish, sunflower seeds, sesame seeds and soybeans).

Vitamins are essential to normal cell function, growth and a healthy metabolism. Vitamins are grouped into two categories: water-soluble vitamins (9), which the body must use right away, and fat-soluble vitamins, which are stored in the body’s fatty tissue and can become toxic if consumed in large quantities. Long heating of various foods leads to the loss of water-soluble vitamins, and even keeping those foods in the water for too long.

Minerals do not provide energy but have an important role in the physiological functions of the body, including the nervous system’s operation correctly, the skeletal structure, the reactions that occur in cells and even water balance. There is a daily requirement of minerals that needs to be brought in our food intake.

Water is very important because is used bu the body as a solute for many nutrients, among many other functions:transports nutrients and hormones to their destination.
There are a lot of unexpected resources from where we can draw our water intake such as fruits and vegetables and processes of the metabolism. Still the most important resource remains the direct drinking of water. In order to maintain your body hydrates you should drink around 8 glasses of water per day.
