What are Proteins?
Proteins play a vital role in our lives.They are the building blocks of most of our body tissues, such as skin, muscle, nails, and tendons among others.
Proteins also take part in many metabolic functions such as nutrient absorption, transportation of oxygen, and they even help deactivate toxic substances.
Proteins are large molecules that are built by chains of amino acids. There are about 20 different types of amino acids that can be combined in any sequence or number to form different types of protein.
Where Does Protein Come From?
Proteins can either come from animal or vegetable sources.
Protein that come from animal sources can be found in red meats, fish, poultry, eggs and dairy products. On the other hand, vegetable sourced protein can be found in dry fruits, soy, legumes, mushrooms and whole grains.
Animal protein contains a larger number and diversity of amino acids. In general their biological value is greater than vegetable protein. However, animal proteins are harder to digest.
When we consume red meats, poultry, and / or fish, we are not only consuming protein, but we also intake metabolic waste such as uric acid and ammonia that are present. These elements are toxic. A smart way to consume animal based proteins and yet avoid these toxic elements is by eating eggs, and dairy products.
Of course, when we consume vegetables, these toxins are not present.
When we consume animal protein, we are very likely to also be consuming saturated fats that are present in meat. High levels of saturated fat can increase the risk of cardiovascular diseases and promote obesity.
