Before we go into detail about protein in nutrition let's first briefly explain what it is and how it is classified. 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. Read on to discover the benefits of protein and its role in our health. Continue reading to find out more about this important 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 was the first to coin the term protein. His name comes from the Greek proteios which means "first in line". Proteins differ by organ, so proteins found in muscles are different from those found within the brain and liver. There are many types and roles of protein in nutrition.
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 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
Various sources of protein are found in plants and animals. Although animals are considered the best source, there are limited nutritional benefits to plant sources. Complete protein sources contain all nine essential amino acid. Vegetable sources, however, lack at least one essential amino acid. The quality of a particular protein depends on its source, quality, and ability to be digested. Animal protein is of high biological value while plant protein has only two essential amino acid.
Health benefits
It's clear that Americans don’t get enough protein. However, supermarket shelves are stocked with many products claiming to be “great sources of protein.” The Dietary Guidelines for Americans found that teenagers eat more meat and poultry than they should. These products are not only promoted to improve diet quality, they also have 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. Protein from animal sources is the primary source of protein for the daily requirement, but recent developments in plant-based foods have shifted the 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 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. Protein's role in metabolism may be more important than its direct contribution in energy production. It is therefore crucial to consider your protein intake and adjust it accordingly.
MetS Impact
MetS's impact on protein intake is not well understood. MetS risk was lower for animal proteins than for plant proteins. Inverse associations between plant protein and WC support the idea that MetS can be prevented by consuming higher amounts of plant protein. A British Journal of Nutrition study has also suggested that MetS could be prevented by higher intakes of plant protein.
FAQ
How Much Weight Can You Lose in a Week?
Your current bodyfat percentage determines the amount of weight you will be able to lose. The first thing to do is to calculate how much weight you want to lose and then find out what your BMI (Body Mass Index) is. Your BMI will tell you how much weight to lose.

If you are 200 lbs, your BMI will be 28.7. To reach a healthy weight, you would need to lose 70 pounds. To see if you're overweight, visit www.healthyminds.com/bmi/.
You can calculate the number of pounds you'll lose each week by knowing your BMI.
(Your Goal Weight - Current Weight)/BMI * 7 Number Of Pounds Lost Per Week
If you want to lose 50 pounds in one month, you'd need 2 weeks' worth of exercise, which equals 56 days, divided by 7 pounds lost per day. This equates to an average of 8.3lbs per week.
