Before we get into the details on protein in nutrition, let us first give you a brief overview of what it is. Protein is an essential nutritional element that plays an integral role in almost all biological processes. Amino acid is the building block of protein and gives cells structure. 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 organisms have proteins. Some are more complex than others. Proteins are vital because they play a direct or indirect role in the chemical processes that enable life to exist. Jons Jacob Berzelius in 1838 first coined protein. Its name derives form the Greek term proteios meaning "first in a line." Proteins are organ-specific. The proteins found in muscles may differ from those in the brain or liver. There are many kinds of proteins, and the role of protein in nutrition can be very varied.
Structure
A protein can be described as a macromolecule of complex amino acids. Its primary structure is the sequence of amino acids within a polypeptide chain. Insulin, for example, is made up of two polypeptide chain, one with amino acid in the N, and one with amino acid in the C. Each chain contains its own sequence. Each amino acids has its own side chains, which are represented by the "R" in this diagram.
Sources
Both plants and animals can provide protein. Although animal sources are the best source of protein, they have limited nutritional value. A complete protein source contains all nine essential amino acids. The essential amino acids found in vegetable sources are absent. The quality and availability of a protein will depend on its source, the quality of its digestion, and its digestibility. Animal protein is of high biological value while plant protein has only two essential amino acid.
Health benefits
Americans aren’t getting enough protein. But grocery stores have tons of products that claim to be great sources of protein. The Dietary Guidelines for Americans states that teens eat far more meat, poultry, or eggs than they should. These products are marketed to increase diet quality and offer health benefits.
Plant-based sources are better than animal-based.
A balanced diet is vital to a healthy life, but the lack of a balanced diet can result in a variety of health problems. Though protein from animal sources is the main source of the daily protein requirement, recent advances in plant-based foods have made it more balanced. Animal-based products are more expensive and environmental-unfriendly. Animal-based products use 100 times more water than plant-based protein.
Metabolic effects
Research suggests that protein intake contributes 2% to 3% of the body's energy requirements during exercise and 12% after several hours of physical work. But this contribution may be larger than the direct effect of protein on energy supplies. Protein's role in metabolism may be more important than its direct contribution in 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. While animal proteins were associated with a lower risk of MetS, plant proteins were associated with a higher risk of the disease. The inverse association between plant proteins and WC supports our belief that a higher intake plant protein could prevent MetS. A British Journal of Nutrition study has also suggested that MetS could be prevented by higher intakes of plant protein.
FAQ
What is the best activity for busy people?
The best way to stay fit is by doing exercises at home. You don't have to join a gym or go to a fitness center to stay fit. It is possible to perform basic exercises at home with minimal equipment.
