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 nutrient and plays an important part in nearly all biological processes. Amino Acides are the building blocks of proteins and give cells structure. Read on to discover the benefits of protein and its role in our health. This vital nutrient is discussed in detail below.
Function
All living things have proteins and some are very complex. Proteins are crucial because they either directly or indirectly participate with chemical processes essential for life. Jons Jacob Berzelius coined the term "protein" in 1838. This name is derived from the Greek word proteios (meaning "first inline") Proteins are organ-specific. This means that proteins found in muscle tissue differ from those found brain and liver. While protein plays a variety of roles in nutrition, there are several types of proteins.
Structure
A protein is a complex macromolecule made of amino acid. The primary structure of a protein is the sequences of amino acids in 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 acid is represented in the diagram by an "R".
Sources
There are many sources of protein, both in animals and plants. Although animal sources are the best source of protein, they have limited nutritional value. Complete protein sources contain all nine essential amino acid. In contrast, vegetable sources lack at least one of these essential amino acids. The quality of a particular protein depends on its source, quality, and ability to be digested. Animal protein has a high biological worth, while plant proteins only contain two essential amino compounds.
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 items also require 100x more water than plants-based proteins.
Metabolic reactions
Research indicates that protein intake contributes approximately 2% to 33% to the body’s energy requirements when exercising and about 12% after a long period of physical activity. However, this contribution could be more important than the direct effects protein has on energy supply. 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
MetS is poorly 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 published a study that suggested that MetS might be prevented if there is a higher intake of plant protein.
FAQ
Why is exercise important for weight loss?
The human body has incredible capabilities. It was designed to move. Whether we are walking, running, swimming, biking, lifting weights, playing sports, dancing, jumping rope, riding our bikes, or just standing still, moving our bodies helps us stay healthy.

Burning calories is how much energy your body uses during physical activity.
-
Exercise reduces appetite. Working out will help you to eat less and make you feel fuller all day.
-
Exercise increases strength. Muscle tissue requires more energy to function than fat tissue. To maintain your current weight, you'll need less calories if muscle mass is increased.
-
Exercise releases endorphins. Endorphins are hormones which make you happy. They are released when you exercise. Studies have shown that endorphins can block pain signals reaching your brain. This creates a sense of well being.

Statistics

- According to Harvard Health, it's estimated that a 155-pound (70-kg) person burns roughly 112 calories per 30 minutes of weight training (5). (healthline.com)
- According to a study sponsored by the American Council on Exercise, a person weighing around 140 pounds (64 kg) would burn 108 calories at a 30-minute beginner's Pilates class or 168 calories at an advanced class of the same duration (26). (healthline.com)
- According to Harvard Health, it's estimated that a 155-pound (70-kg) person burns around 167 calories per 30 minutes of walking at a moderate pace of 4 mph (6.4 km/h) (5). (healthline.com)
