A B C of Protein

The building block of life - Protein!

Did you know our body can not store proteins? This is why we need to have a steady supply of it daily. To better grasp the answer to that question, it is necessary to first understand the basics of nutrition and its essential features.

Nutrition is an important aspect of health and development. Better nutrition is associated with better baby, child, and maternal health, stronger immune systems, safer pregnancy and delivery, a decreased risk of noncommunicable illnesses (such as diabetes and cardiovascular disease), and longer life.

Now when talking about Nutrition the very crucial thing to understand is the macronutrients. Macronutrients are the nutritional components of food that the body needs for energy as well as to sustain the structure and functions of the body. These are of 3 types: carbohydrates, fat, and protein. They are the nutrients that you consume the most.

And, for the time being, let's concentrate on the protein. Protein is found in every cell of the human body and is required in your diet to help your body repair and create new cells. Also necessary for the growth and development of children, adolescents, and pregnant women.

Several analytical and scientific data support the ingestion of protein regularly. Protein reduces appetite and hunger, increases muscle mass and strength, benefits bones, improves metabolism resulting in fat burning, lowers blood pressure, aids in weight loss maintenance, aids in rapid healing and repair of injuries, aids in the reduction of late-night cravings, and aids in the graceful aging of the body.

To know the functionality and advantages of protein in human health it's important to learn the protein quality and one of the most integral methods to determine the protein quality is the PDCAAS. It's a Protein digestibility-corrected amino acid score; it's a method of determining the quality of a protein based on both human amino acid requirements and digestive ability. Protein quality is a measure of how well a protein meets the amino acid needs of the organism as well as its physiological demands. It is based on an amino acid scoring method that compares the essential amino acid composition of the protein to the needed pattern.

Protein quality is affected by the amino acid profile of the food, the quantity of necessary and limiting amino acids, as well as their digestibility and physiological utilization after digestion.

Example values[edit]

A PDCAAS value of 1 is the highest, and 0 is the lowest. The table shows the ratings of selected foods. (others[11])

Protein may be obtained from a variety of sources like:

  • Beef, lamb, veal, and pork are examples of lean meats.

  • Poultry such as chicken, turkey, duck, goose, and eggs.

  • Fish, prawns, crabs, lobster, oysters, and clams are examples of seafood.

  • Milk, yogurt, cheese, and paneer are examples of dairy products.

  • Plant protein sources include pulses such as lentils, chickpeas, and beans; nuts such as almonds and peanuts; seeds such as chia seeds and hemp seeds; grains, soy, tofu, tempeh, edamame, spirulina, quinoa, and mycoprotein such as mushrooms.

In recent times the trend and upcoming research have taken a particular interest in plant-based proteins, due to a variety of possible health benefits as well as their positive environmental impact. The long-term health and illness advantages of plant proteins have been a prominent trend in recent years. Recent data and analytical evaluations highlight the relevance of plant protein and its benefits in strategic intervention.

Several health benefits of plant proteins are as follows:

Manages blood sugar levels:

According to the latest research, a plant-based diet can help regulate blood sugar levels and insulin resistance, the two most important aspects of living with diabetes. Through another randomized control experiment, the advantages of a low-GI legume-rich diet were compared to the benefits of a high-insoluble-fiber diet, such as whole wheat. The study indicated that individuals who followed the legume-rich diet, which pushed participants to increase legume intake by at least 1 cup per day, had an average drop in hemoglobin A1C levels that were larger than those who followed the insoluble fiber diet.

Lowers cholesterol level:

Consuming plant-based protein can also help decrease cholesterol, which is linked to a lower risk of heart disease. It's no secret that red meat and animal proteins have been linked to higher cholesterol levels for a long time. So, if this is a major health problem, switching to the plant-based quality protein under the supervision of a health professional might be a wise decision.

Reduces the risk of CVD:

Stanford University researchers discovered that a diet including an average of two meals of plant-based meal replacements can decrease several cardiovascular risk factors. Several studies have revealed that although eating red meat increases the risk of some illnesses, switching to plant-based proteins can help lower the risk.

Making the switch to plant-based proteins has been proven to reduce the risk of cardiovascular disorders including cardiac arrest and coronary artery disease, which is one of the most often claimed benefits of plant-based proteins.

Healthy weight loss:

Protein-rich meals are associated with maintaining a healthy weight and help in weight reduction, most likely owing to protein's capacity to help you feel satisfied as it regulates hunger hormones. Since many plant protein sources are lower in calories than animal protein and can amplify these benefits, maintaining a calorie deficit is linked to long-term weight loss.

Even after knowing the benefits of Consuming Enough Protein, it's easy to forget about protein consumption in this stressful life. This may not look like a big thing, but in a long run, it may have a greater influence on our health.

The topmost priority is to ensure that adequate protein is consumed throughout the diet by including all protein-rich foods. If that appears to be too challenging, switching to a protein supplement with the assistance of a health specialist such as a physician or nutritionist is a smart move.

When a high-protein diet is recommended, special consideration should be given to the source of the proteins as well as the overall quality of the food. Individualized protein nutrition should be taken according to an individual's genetic background, food, lifestyle, and microbiome, and nutritional guidance should better include the different protein intake requirements.

Protein cannot be stored in the body, because the amino acids oxidize and convert to urea. To function effectively, protein requires an external supply of high-quality oxygen. It cannot store or manufacture on its own, which implies that when there is no food in the stomach, our cells can benefit from various nutrients to sustain their multiple tasks. When carbs reach the stomach, however, all of this changes, and they will naturally move towards producing energy for our bodies when they are most needed. Due to inadequate carb extraction when ingested with proteins, this leaves less area for protein utilized in cellular repair activities.
