Soy Protein: What Is It, Why We Need It And Best Food Sources

The Popularity of Soya Protein

Soy protein has gained much attention among health enthusiasts in recent years. This product plays an important role in health and disease prevention and makes a great addition to a healthy diet.

According to a recent study, individuals who lead a health-conscious lifestyle (who didn’t consume meat, but, ate fish or were vegetarians/vegans) were more inclined to use soy products than the average person. Overall, there is a high demand for soy protein and products made from it as people look to eat a healthier diet.

What Is Soy Protein?

Soy protein comes from soy beans. Soy beans are dehulled and defatted to make three different kinds of products:

  • Soy Flour
  • Soy Concentrates
  • Soy Isolates

Soy protein is very nutritious, and it has very little fat, no cholsterol, and it is high in fiber and protein. It has been used regularly to create various food products as substitutes for high fat dishes, including:

  • Soy bacon
  • Soy cheese
  • Various meat alternatives, such as, soy burgers and hot dogs
  • Soy ice cream

Health Benefits of Soy Protein

1. Soy protein is a good source of heart-friendly Omega 3 fatty acids, therefore, incorporating soy protein into your diet can help prevent heart disease.

2. Soy protein is a great substitute for traditional protein sources, such as, meat as it contains much less fat, but, still provides useful amino acids just like meat.

Amino acids play an important role in maintaining muscles and reducing fat in the body and also aid in the formation of insulin. So, if you want a healthy source of amino acids, it is best to choose soy protein foods instead of meat, which, is loaded with fat.

3. Soy protein is full of fiber that helps with digestive health, weight control, preventing high cholesterol, and regulating blood sugars

4. Soy protein is naturally cholesterol free.
Eating soy products can help you lower LDL or ‘bad’ cholesterol by about 3%. Not a huge reduction, but, every little bit helps in the battle against cholesterol. Doctors suggest that even a 1% drop in cholesterol, reduces chances of heart disease by 2%, and soy protein can help.

5. Also, soy can help fill the gap for those that must limit their animal protein intake and cannot enjoy foods like burgers and hot dogs.
