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 nutritional element that plays an integral role in almost all biological processes. Amino Acides are the building blocks of proteins and give cells structure. Learn more about protein and how it affects our health. This vital nutrient is discussed in detail below.
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 in 1838 first coined protein. Its name derives form the Greek term proteios meaning "first in a line." Proteins can be found in different organs, so those found in the muscles will differ from those in brain and liver. There are many types and roles of protein in nutrition.
Structure
A protein is a macromolecule that is complex and made up of amino acids. Its primary structure is the sequence of amino acids within a polypeptide chain. For example, insulin is composed of two polypeptide chains, one with amino acids in the N and the other with amino acids in the C. Each chain has its own sequence of amino acids. Each amino acids has its own side chains, which are represented by the "R" in this diagram.
Sources
There are many sources of protein, both in animals and plants. Animal sources are the purest sources of protein. However, plants have limited nutritional benefits. A complete source of protein contains all nine amino acids. Vegetable sources, however, lack at least one essential amino acid. The quality of protein depends on the source and quality as well as its ability to digest. Animal protein is of high biological value while plant protein has only two essential amino acid.
Health benefits
It is a fact that Americans aren't getting nearly enough protein in their diets, yet the shelves of grocery stores are full of products claiming to be "great sources of protein." According to the Dietary Guidelines for Americans, teenage boys and men eat more meat, poultry, eggs, and other animal products 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 balanced diet is vital to a healthy life, but the lack of a balanced diet can result in a variety of health problems. While protein from animals remains the most important source for daily protein requirements, recent developments in plant based foods have altered the balance. Animal-based products are more expensive and environmental-unfriendly. Animal-based foods also consume 100 times as many water as plant-based proteins.
Metabolic effects
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. This contribution could be greater than the direct impact of protein on energy supply. The support protein provides for the oxidation glucose and lipids in metabolism could be more important than the direct contribution it makes to energy production. It is therefore crucial to consider your protein intake and adjust it accordingly.
Impact on MetS
We are still not sure of the effect of protein in nutrition on MetS. MetS risk was lower for animal proteins than for plant proteins. The inverse association between plant protein and WC supports the idea that a higher intake of plant protein may prevent MetS. A British Journal of Nutrition study has also suggested that MetS could be prevented by higher intakes of plant protein.
FAQ
How can busy people lose weight
Losing weight is as easy as eating less and working out more.
You will gain weight if your eat too much. If you don't exercise enough, you'll also gain weight. Combining these two simple habits will help you lose weight.

For example, if your goal is to lose 10lbs, aim for 300 minutes of moderately intense exercise per week. This includes activities such brisk walking and swimming laps, bicycling, dancing, playing tennis or golfing, hiking, running, jogging and other similar activities.
Consider doing 20 minutes of vigorous exercise thrice a week if you are just starting out. This could be lifting weights, sprinting, jumping rope, and fast walking.
Aerobic exercise also helps burn calories and build muscle mass. Muscles burn more calories than fat. So building muscle can help you lose weight faster.
