High Protein Foods are good for our health as protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.
It also improves health in various ways, such as helping you lose weight and belly fat, while increasing your muscle mass and strength.
A diet high in protein also lowers blood pressure, fights diabetes and more while deficiency in protein leads to muscle atrophy and impaired functioning of the human body in general.
Other symptoms of protein deficiency includes:
- wasting and shrinkage of muscle tissue
- oedema (build-up of fluids, particularly in the feet and ankles)
- anaemia (the blood’s inability to deliver sufficient oxygen to the cells, usually caused by dietary deficiencies such as lack of iron)
- slow growth (in children).
Proteins are made up of chains of smaller chemicals called amino acids and since the human body cannot store amino acids, so it must be supplied daily from the foods we eat.
For this reason, it is recommended that you should eat high-quality protein at every meal using the recommended daily intake (RDI) for protein of 46 grams for women and 56 grams for men.
Also very high protein foods or diets intake are dangerous because excess of everything is bad!
And some of the problems with very high-protein foods/diets include:
- They usually promote a very low intake of carbohydrates. Glucose, made when your body breaks down dietary carbohydrate, is your body’s preferred fuel source. If your body does not receive enough dietary carbohydrate, it will break down muscle tissue to make glucose. This causes muscle wastage, reduced metabolism and a build-up of ketones.
- Fibre is largely a carbohydrate. Foods rich in carbohydrates (such as whole-grains and legumes) are also rich in fibre. Avoiding these foods leads to an overall low-fibre intake, which can result in constipation, bowel disorders and increased risk of colon cancer.
- There is evidence to suggest that the heart may not function as well if its main source of fuel is ketones.
- High intake of animal products (which is usually recommended in such diets) can also be high in saturated fats and cholesterol, which is associated with a range of conditions including heart disease.
- The liver and kidneys are put under strain because they have to detoxify and eliminate unusually high quantities of protein byproducts. Kidney problems may be exacerbated in people with diabetes.
- There is an increased risk of developing gout and gall bladder colic.
- Greater losses of body calcium may increase the risk of osteoporosis.
- High-protein diets can cause mild dehydration due to increased water loss through urine. Increased risk of dehydration puts the body under pressure.
- Recent research shows that weight loss over one year is not greater on a high-protein diet when compared to safer, low-fat eating patterns.
Today, we are going to be discussing about the complete list of high protein foods you should know about that will greatly benefit your health but first we need to understand how protein actually works in our body.
How Protein Works in Our Body
Brain cells, muscle, skin, hair and nails are just some of the body parts that are protein-based. Estimates suggest that about half of the human body’s dry weight is made up of protein.
Many of the foods we eat contain protein, particularly flesh foods (chicken, beef, lamb and fish), and legumes like beans and lentils.
These proteins are broken down during digestion to release amino acids, which are the building blocks of all proteins.
Once inside the body, these amino acids are used to make new proteins including enzymes and hormones such as adrenalin. Proteins are sometimes also used as an energy source.
A protein-rich food, such as meat for instance, is broken down into individual proteins by the gastric juices in your stomach.
Then the pancreatic enzymes released into the first portion of your small intestine (duodenum) split the proteins into their separate amino acids. The amino acids are absorbed by the small finger-like projections (villi) lining the intestine walls, and are taken to the liver via the bloodstream.
Then the human body uses those amino acids in these three main ways:
- Protein synthesis – new proteins are created constantly. For example, as old, dead cells are sloughed off the skin surface, new ones are pushed up to replace them.
- Precursors of other compounds – a range of substances are created using amino acids, (for example, the brain chemical (neurotransmitter) serotonin and the ‘fight or flight’ chemical adrenalin).
- Energy – although carbohydrates are the body’s preferred fuel source, about 10 per cent of energy is obtained from protein.
Complete List of High Protein Foods
