What Is Plant-Based Protein?

Plant-based proteins are derived entirely from plants. These proteins can come from various sources like legumes, grains, nuts, and seeds. 

Innovations in food technology also lead to plant-based protein products that mimic the texture and flavor of traditional animal proteins, broadening the appeal and accessibility of plant-based options.

Sources and Types

The diverse world of plant-based protein includes sources like:

  • Legumes: Such as peas, lentils, soybeans, chickpeas, and black beans.
  • Grains: Including quinoa, rice, and barley.
  • Seeds and Nuts: Such as chia seeds, flaxseeds, almonds, and cashews.

Unlike animal-based proteins, these sources often lack one or more essential amino acids but can be combined to form complete protein profiles. However, some sources are considered complete proteins, meaning they contain all the essential amino acids, such as quinoa and soy.

How Is Plant-Based Protein Made?

Plant-based protein is extracted from the source through various methods like milling and grinding. These sources are processed to remove fats and carbohydrates, leaving behind concentrated protein. The result can be found in protein powders, bars, and fortified foods.

What Is Whey Protein?

Whey protein is a complete protein derived from milk during the cheese-making process. This highly regarded protein source is popular among athletes and fitness enthusiasts due to its rich amino acid profile and high digestibility. 

It contains all the essential amino acids the human body needs and is quickly absorbed, making it a preferred choice for post-workout recovery.

Sources and Types

Whey protein primarily comes from cow's milk, although other specialized sources may exist. 

There are several types of whey protein, based on how it's processed:

  • Whey Protein Concentrate (WPC): Contains lower levels of fats and carbohydrates and varying protein percentages depending on how concentrated it is. It retains more of the beneficial nutrients found in whole whey.
  • Whey Protein Isolate (WPI): Further processed to remove most of the fat and lactose, leaving behind 90 percent or more protein. Ideal for those who want higher protein content with fewer calories.
  • Whey Protein Hydrolysate (WPH): Pre-digested and partially hydrolyzed for easier metabolism. This form may reduce potential allergic reactions and is easier on the digestive system.

How Is Whey Protein Made?

Whey protein is a byproduct of cheese production. When rennet is added to milk, it separates into curds and a liquid substance known as whey. 

The whey is then filtered and purified through various processes, depending on the desired type of whey protein. Afterward, it is dried into powder, ready to be mixed into shakes or used in other products.
