Before we get into the details of protein in nutrition, let's first have a quick overview of what it is and how it is categorized. Protein is an essential nutrient that plays an important role in almost all biological processes. Amino acids are the building blocks of protein and provide cells with structure. Find out more about the role of protein in our health and the benefits it brings. This vital nutrient is discussed in detail below.
Function
All living things contain proteins, some of which are extremely complex. Proteins are vital because they play a direct or indirect role in the chemical processes that enable life to exist. The term protein was first coined in 1838 by Jons Jacob Berzelius, whose name derives from the Greek word proteios, meaning "first in line." Proteins can be found in different organs, so those found in the muscles will differ from those in brain and liver. While protein plays a variety of roles in nutrition, there are several types of proteins.
Structure
A protein is a macromolecule that is complex and made up of amino acids. The primary structure of a protein is the sequences of amino acids in a polypeptide-chain. Insulin is an example of a polypeptide chain that includes amino acids in both the N and C. Each chain also has its own sequence. In the diagram below, every amino acid has its own side chain. The "R" stands for each.
Sources
Plants and animals both have different sources of protein. Although animals are considered the best source, there are limited nutritional benefits to plant sources. A complete source of protein contains all nine amino acids. The essential amino acids found in vegetable sources are absent. The quality of a protein depends on its source, its quality, and its digestibility. Animal protein has a high biological worth, while plant proteins only contain two essential amino compounds.
Health benefits
While Americans don't get enough protein, the shelves of grocery shops are filled with products that claim to be "great source of protein." In fact, the Dietary Guidelines for Americans report that most teenage men and boys consume more meat, poultry, and eggs than they should. These products not only improve diet quality but also offer a range of health benefits.
Plant-based sources over animal-based
A healthy diet is crucial for a healthy life. However, eating a poor diet can cause many health problems. Although animal protein is the best source of protein for your daily needs, plant-based foods are changing that balance. Animal-based products are more expensive and environmental-unfriendly. Animal-based products also require 100 times more water to make than plant-based proteins.
Metabolic reactions
Research shows that protein intake contributes between 2% and 3% to the body's energy needs during exercise, and between 12% and 13% after hours of hard work. However, this contribution may be more significant than the direct effects of protein on energy supply. The role of protein in metabolism in supporting the oxidation of glucose and lipids may be more significant than the direct contribution to energy production. It is therefore important to adjust your protein intake accordingly.
Impact on MetS
MetS is poorly understood. MetS risk was higher in animal proteins than in plant proteins. A positive association between plant protein intake and WC supports the notion that MetS may be prevented by consuming more plant protein. Further, a study recently published in the British Journal of Nutrition suggested that higher plant protein intake may protect against MetS.
