The role of PROTEINS in our diet

Proteins are the main components of our body (skin, organs, muscles & tendons) and are used to make crucial enzymes and hormones that serve various functions within biological processes. Proteins are responsible for new-cells production, they are essential for growth and they help to repair our tissues&muscles (for example they re-build broken muscle fibres damaged after high intensity or strength workout). They also keep blood sugar on stable level throughout the day and help you limit the intake of calories by eating less food while achieving same satiety.

 

That is why, following protein-quality diet is vital for every person who:

  • aims to stay healthy,
  • lives active lifestyle (& does exercise),
  • wants to loose weight

 

Apart of boosting metabolic rate and reducing the appetite, proteins limit the amount of fat people regain after weight loss and help build and preserve muscle mass. However proteins are made of amino acids mainly produced by body itself, in order to boost their levels – it is vital to know their best food sources.

 

For the average adult who is on 2000-2500 calories diet, does not exercise much but is at a healthy weight, the optimal daily intake of proteins is around 75g (male) or 60g (female). People who want to build muscle mass and strength need to increase the amount as well as elderly people or those with physically demanding job. The good news is, you can not overdose proteins- there is no scientific evidence that a reasonably high protein intake has any adverse health effects.

The best sources of proteins are animal products (meat, fish, dairy) as they have all the essential amino acids, but vegetarians & vegans can also fill their diet with proteins by eating specific vegetables, seeds and nuts.
