Tag: Incomplete proteins

The human body requires 20 different amino acids to function, but it can only produce 11 of them. The remaining nine, known as essential amino acids, must be obtained exclusively through diet. This process involves the digestion of proteins from food sources, their breakdown into individual amino acid components, and their subsequent absorption into the bloodstream for use throughout the body.

Not all protein sources are created equal; research shows significant differences in amino acid composition and digestibility. This means that when asking, "is all dietary protein the same?", the answer is a definitive no.

Proteins are made up of chemical building blocks called amino acids, and your body uses them for everything from building tissues to making hormones. Understanding what kind of protein is dietary protein involves breaking down this macronutrient into its basic components and learning its critical role in the body.

As much as 35-40% of the essential amino acids found in your body's muscle proteins are branched-chain amino acids (BCAAs). Given their importance, many people wonder: do all proteins have BCAAs? The answer depends on the protein source and whether it is considered complete or incomplete.

According to nutritional science, not all dietary proteins are created equal, with some sources providing more complete amino acid profiles and better digestibility than others. This leads many to wonder, is there such a thing as low quality protein, and how does it impact your health?

Over 80% of plant proteins found in sweet potatoes come from unique proteins called sporamins. All vegetables, along with most other plant-based foods, contain incomplete proteins, meaning they lack or are low in one or more of the nine essential amino acids. This doesn't mean they are nutritionally inferior, but rather requires a varied diet to obtain a complete amino acid profile throughout the day.

According to Harvard's T.H. Chan School of Public Health, proteins are fundamental macronutrients composed of amino acids that can be sourced from both plants and animals. Debunking the common misconception, the answer to "Are all proteins plant-based?" is a definitive no, as both sources offer distinct nutritional profiles that are vital for bodily functions.

Most plant-based proteins are considered 'incomplete' because a food source does not contain all 9 essential amino acids in sufficient quantities. However, by strategically combining different plant foods, you can easily obtain a complete amino acid profile.

According to the American Dietetic Association, plant protein can meet protein requirements when a variety of plant foods is consumed and energy needs are met. The process relies on understanding how different plant foods, each with their own amino acid profile, can be strategically combined to create a complete protein source for the body.

Protein is part of every cell, tissue, and fluid in our bodies, and the body uses 20 different amino acids to make its proteins. Many plant-based proteins have different amino acid profiles. This is where complementation in nutrition comes into play, a practice historically important for plant-based diets.
