Let's start by briefly defining protein and its classification before we dive into details about nutrition. Protein is an essential nutrient and plays an important part in nearly all biological processes. Amino acids, which are the building blocks for protein and give cells their structure, are essential nutrient. Learn more about protein and how it affects our health. Continue reading to find out more about this important nutrient.
Function
All living creatures have proteins. Some of them are complex. Proteins are crucial because they either directly or indirectly participate with chemical processes essential for life. 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, so the ones found in muscles differ from those found in the brain and liver. There are many kinds of proteins, and the role of protein in nutrition can be very varied.
Structure
A protein is a macromolecule that is complex and made up of amino acids. Its primary structure is the sequence in which amino acids are found within a polypeptide chains. 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. In the diagram below, each amino acid has its side chain. This is represented by an "R".
Sources
Both plants and animals can provide protein. Although animal sources are the best source of protein, they have limited nutritional value. The complete protein source must contain all nine of the essential amino acids. In contrast, vegetables are deficient in at least one of the essential amino acids. Quality of a protein is dependent on its origin, quality and 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." The Dietary Guidelines for Americans found that teenagers eat more meat and poultry than they should. These products are not only designed to improve your diet, but they also offer many health benefits.
Plant-based sources over animal-based
It is essential to have a healthy diet. However, it can lead to various 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 items also require 100x more water than plants-based proteins.
Metabolic Effects
Research has shown that protein intake contributes to between 2% and 33% of the body’s energy needs when exercise is done, and between 12-12% after prolonged physical exertion. This contribution could be greater than the direct impact of protein 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 therefore important to adjust your protein intake accordingly.
MetS Impact
The impact of protein in nutrition on MetS remains poorly understood. MetS was associated with animal proteins, but not plant proteins. A positive association between plant protein intake and WC supports the notion that MetS may be prevented by consuming more plant protein. A British Journal of Nutrition published a study that suggested that MetS might be prevented if there is a higher intake of plant protein.
FAQ
Are cardio exercises a good way to lose weight quickly?
Cardio exercises are great at burning calories but don't help you lose weight. It all depends on how many calories you've stored and what type exercise you do.
