Before we get into all the details of protein nutrition, let's first go over what it is. Protein is an essential nutritional element that plays an integral role in almost all biological processes. Amino amino acids are the building blocks and structure of protein. You will learn about the many benefits of protein as well as its importance in our health. Read on to learn more about this crucial nutrient.
Function
All living things have proteins and some are very complex. Proteins are essential because they participate directly or indirectly in the chemical reactions that make life possible. Jons Jacob Berzelius first coined the term protein in 1838. The name derives its Greek origins from proteios, which means "first in line". Proteins are organ-specific. The proteins found in muscles may differ from those in the brain or liver. While protein plays a variety of roles in nutrition, there are several types of proteins.
Structure
A protein is a complex macromolecule made of amino acid. Its primary structure is the sequence of amino acids within a polypeptide chain. Insulin, for instance, is composed of two different polypeptide chains. One contains amino acids from the N while the other has amino acids from the C. Each amino acid has its own amino acid side chain, which is represented by an "R" in the diagram below.
Sources
There are many sources of protein, both in animals and plants. Although animal sources are the best source of protein, they have limited nutritional value. A complete source of protein contains all nine amino acids. In contrast, vegetable sources lack at least one of these essential amino acids. The quality of protein depends on the source and quality as well as its ability to digest. Animal protein has high biological value, while plant protein contains only two essential amino acids.
Health benefits
It's a fact that Americans don't get enough protein. Yet, grocery stores stock many products touting to be "great sources" of protein. The Dietary Guidelines for Americans found that teenagers eat more meat and poultry than they should. These products not only improve diet quality but also offer a range of health benefits.
Plant-based sources over animal-based
Healthy living requires a balanced diet. But, an unhealthy diet can cause a host of health problems. Although protein from animals is the main source of protein, recent developments in plant-based food have changed the balance. Animal-based products are more expensive and environmental-unfriendly. Animal-based products use 100 times more water than plant-based protein.
Metabolic effects
Research indicates that protein intake is responsible for 2% to 3.3% of the body’s energy requirements in exercise and 12% when working out. However, this contribution could be more important than the direct effects protein has on energy supply. The support of oxidation of glucose, lipids and protein in metabolism might be more important that its direct contribution towards energy production. It is crucial to account for protein intake and adjust it accordingly.
MetS: Impact
It is still not clear what the impact of protein nutrition on MetS is. MetS was associated with animal proteins, but not plant proteins. The inverse association of plant protein with WC supports that MetS could be prevented if there is a greater intake of plant proteins. Further, a study recently published in the British Journal of Nutrition suggested that higher plant protein intake may protect against MetS.
FAQ
Why exercise is important to weight loss
The human body is an amazing machine. It was designed to move. Whether we are walking, running, swimming, biking, lifting weights, playing sports, dancing, jumping rope, riding our bikes, or just standing still, moving our bodies helps us stay healthy.
