Protein is necessary for growth, repair, and maintenance.
1g of protein equals 4 kcal.
Proteins can be obtained by animals and plants.
Animal sources of protein, also known as having high biological value, contain all of the essential amino acids.
Low-biological-value foods, such as vegetables,beans,lentils,pulses, and grains, don't contain all of the essential amino acids and are usually missing at least one.
Proteins are made up of carbon, hydrogen, oxygen, and nitrogen.
Proteins are made up of amino acids.
There are 20 amino acids that combine to make up millions of proteins.
Our body breaks down proteins into amino acids, which are the building blocks of all proteins.
Essential amino acids are amino acids that must be supplied to us through our diets and are known as indispensable.
Non-essential amino acids are amino acids that can be made by our bodies and are known as dispensable.
The recommended nutrient intake (RNI) is dependent on a person's weight, age, and health.
The amount of protein per 100g in foods such as white rice, pasta, white bread, cheese, poached egg, rump steak, peanuts, and others is also provided.
Protein deficiency is rare in the UK but can be a problem in developing countries.
Pem (protein energy malnutrition) is when a range of disorders are usually in young children.
The main two types of Pem are marasmus and kwashiorkor.
Marasmus condition normally occurs in children under one, when they are weaned off of breast milk too quickly and onto a diet that has LBV products, marasmus can occur.
Children can become underweight, weak, and lethargic due to marasmus.
Kwashiorkor occurs in children who are weaned onto a diet that is high in starchy food and low in energy and protein, this often follows an acute infection such as gastroenteritis.
Symptoms of excess protein that you don't use for growth and repair get used for energy and will be stored, which could contribute to weight gain.
High-protein diets, known as the Atkin diet, have been used as a treatment for obesity.
