A healthy diet must contain protein. Most people consider meat the most potent protein, but swapping meat for other proteins like nuts and grains increases lifespan. The dietary guidelines published in 2016 suggest that people should concentrate on other protein sources instead of meat. The publication is not suggesting that people avoid meat but make various proteins to remain healthy.

What is Protein?
Protein is one of the essential food nutrients that helps the body grow. They are the building blocks responsible for digesting amino acids to help grow and repair the body. Protein is digested in the body to form skin, hair, and muscle. There are animal and plant-based proteins like soy, Quorn, and quinoa. These spices contain essential amino acids for the restoration of the body.
Meat is a complete protein, vegetables do not lack protein, and there are no guidelines or combinations for eating plant-based protein. But eating different plant proteins daily harnesses the essential amino acids we need.
How Much Protein Do I Need?
Adults are advised to eat about 0.75g of protein for every kilo of their body weight. In essence, women need 45g while men need 55g. However, humans must take two portions of meat, nuts, fish, or tofu daily. On the contrary, many people consume twice the recommended amount, making them vulnerable to cancer, heart disease, and diabetes and shortening life spans. As a result, one should focus more on peas, lentils, and beans, eat fish twice a week, and below 70g of red or processed meat daily.
Things You Should Know About Protein
1. Three Types of Amino Acid Exist
There are essential, non-essential, and conditionally essential acids.
- The essential acids are 9 of the 20 amino acids the body needs. Unfortunately, the body cannot generate these acids, which leaves us no choice but to supply them artificially.
- The non-essential acids are the digested protein by the essential acids. These proteins are in many forms and foods but are not essential for daily consumption. There are four in all.
On the other hand, conditionally essential acids are in many foods but not fit for daily consumption. This is because the liver makes the conditionally essential acids from the 9 essential acids digested in the body. Kids use 7 conditionally essential amino acids because their bodies cannot extract enough to meet their health needs.
2. All Proteins are not Created Equal
The level of protein in food varies. Other than the 9 essential amino acids, animals have the highest protein, iron, Vitamin D, and B12. In essence, 100g of meat will produce 32.6g of protein, while 100g of beans can only produce 8.1g of protein. Beef is another significant source of sustainable protein through leucine, essential for muscle mass and growth.
If you are in the game for muscle gain, it is recommended to consume more animal protein to prevent muscle loss. However, plant protein has distinguished benefits, i.e., it contains more fiber, low in fat and calories. In addition, plant proteins like legumes and peanut butter are cheap. Vegans and vegetarians can meet the required protein size by following the proper daily plant-based routine.
3. Various Functions of Protein
- Proteins are enzymes working as catalysts.
- They help the formation of complex molecules like hemoglobin for blood oxygen circulation and storage of protein ferritin and iron in the liver.
- Protein helps in body motion like skeletal muscle.
- Protein contributes to the body’s mechanism through collagen in the skin and bone.
- They aid cells’ response.
- Also, they fight infection and act as antibodies against viruses.
4. Three Categories of Protein
Protein has three categories, such as:
- Structural proteins are the primary framework of the body. The protein is responsible for collagen in the bone and connective tissue, muscle tissue, and keratin in the skin.
- Homeostatic proteins regulate body functions like blood sugar, increase enzyme reactions, and help white blood cells fight diseases.
- Fuel proteins are energy proteins. They can be converted to fatty acids, glucose, or ketones for ATP. The body can convert the protein into the needed energy and has the resources to do so.
5. Protein Against Diseases
Prado’s research aims at the benefits of high-protein diets for cancer patients. The conclusion is that children, pregnant women, obese, diabetes, and active people can benefit by increasing their protein intake. In addition, it is also recommended for people over the age of 45.
Age depreciates body muscle, but the benefit of taking a high-protein diet can prevent muscle loss and may increase body mass. Muscle wasting consumes muscles that can take the body many months or years to rebuild. You can face muscle depletion without knowing because the change is insignificant in appearance. People with average body weight can lose muscle mass unknowingly.
6. Protein Anabolism or Catabolism
Protein is another energy source. After digestion, it can be repaired and grown. These processes are metabolism in small ration within an organ, cell, or organism. Anabolism is the repair and growth of protein by increasing the size of smaller proteins. So, people aiming to increase their weight must be in an anabolic state. In this state, the body will harness enough protein to repair and grow the muscle to ensure you gain weight and muscle mass.
Catabolism is the opposite of anabolism. The process digests protein into smaller amino acids. The body always uses catabolism to repair damaged cells and make new ones. The process repairs cells in the skin, muscles, and the entire body. Catabolism is what repairs micro tears in the muscle during exercise. A meal with sufficient dietary protein will make it easy for the body to repair quickly, recover and grow muscle.
7. Variety is the spice of high-protein meals
Combining different proteins to have a high-protein diet does not mean repeating the same meal daily. In fact, it is about looking for different varieties of plant base and animal-based proteins. The variety should contain foods you are interested in and have additional benefits. For example, animal protein could be beef, bison, pork, fish, eggs, milk, cheese, and poultry.
At the same time, plant-based protein could be lentils, beans, nuts, seeds, quinoa, soy, and buckwheat. For example, you can combine red meat with nuts and fruits. Add salmon and sunflower seeds with salad, black beans, chicken, and rice bowl. In addition, eggs and oatmeal are good breakfast and protein sources. You can also combine plant and animal proteins called sustainable protein.
These are a few of the main functions and information on protein. Professionals suggest we eat protein each day to remain healthy in body weight, cell repair, and muscle growth. Remember to combine plant-based and animal-based proteins.
