What are proteins and why do we need them?

There are three main nutrients in the balanced diets that we eat, and protein is one of them. Fats and carbohydrates are the other two and when taken in the right share, the food is regarded as a balanced diet. Protein is very vital in our bodies and it takes 20% of the total weight of our bodies. We will explain to you why proteins are vital to your body, and the healthy sources you get them from.

Benefits of Protein

The various physiological functions in our bodies require proteins. To the physical part of the body protein is a very important part of the enzymes, tissues and cells that protects us from getting sick. They help us in the following.

They keep our nails, skin and hair healthy

Assist in the production of enzymes in the body

Keeping the immune system functional, so that we do not get attacked by the various diseases.

What are Proteins made of?

They are complex molecules that are of amino acids. The amino acids are joined together in specific combination of exact numbers, which makes every protein unique. The body synthesizes its proteins and to do so it requires proteins from the external sources – different foods – which provides it with amino acids for the production process. As an example you may take protein shakes – if you don’t know much about them you can learn more: http://proteinshakesforwomenworld.com.

In the normal functioning of the body, there is an interaction that goes on between other nutrients and protein, where they bind and enable the supply and circulation of vitamin and other minerals like copper, vitamin A, D, Calcium and Iron. When these components are not properly distributed in your body, it will obviously result to an imbalanced body with impaired functionality. You should therefore ensure that you have adequate intake of protein.

Proteins are also known to make the body feel satiated. People who are looking after losing weight benefit from this factor because they will have the feeling of being full, and hence will not eat a lot making them loose weight fast.

The Healthy Protein Sources

You will get protein from various types of foods. They include dairy, whole grains, eggs, fish, meat, vegetables and beans. The extra content of a healthy meal that is rich in proteins determine whether it is healthy or not. We can have a few examples as explained below.

  • Beans and nut will provide you with protein and they also have fiber that helps with digestion and free movement of bowels

  • Fish is a perfect source of proteins, but their downside is that they usually have harmful components like mercury. They therefore should not be eaten regularly.

  • Eggs have enough proteins, whereas meat becomes the main source of proteins in many people’s meals.

Complete proteins foods are those that contain all the required amino acids. Incomplete proteins on the other hand are those that have some of the amino acids, or do not contain them at all.

Meat, eggs, fish and dairy foods are examples of complete proteins. Vegetarians do not have a source of complete proteins and for them to get all the amino acids they eat a mixture of vegetables and grains.
