What Exactly Is Soy Protein, and Are There Different Types?

Soy protein is a kind of protein that’s derived from soybean plants, and it can be made in three different types: soy protein isolates, concentrates, and soy flour.

When it comes to protein powders, you’ll typically see soy protein isolates, as they have the most qualities to help build muscles. They also contain amino acids that are essential for you to get through your diet, because your body doesn’t naturally produce these acids. It’s great for vegans and other people on restricted diets to consume supplements that contain these amino acids for their nutritional benefits. Due to these acids, soy protein is regarded as a “complete protein.”

Concentrate and isolate both come from soybean meal. The hulls and fats of this meal are removed before it is further processed. Isolate typically has almost zero carbs or fats and is up to 95% protein. Concentrate has carbs further removed and is usually used in cereals, baking, and other types of food products. The concentrate tends to have a lot of fiber, so it’s easy to digest, and is recommended for pregnant women, the elderly, and children who would like to be healthy and support their muscles and bones.

What Are the Benefits of Soy Protein?

You’ll find many benefits from consuming soy protein powder, including:

It’s a great substitute for meat

According to the FDA, soy protein functions well as an effective substitute for animal products and is a great ingredient for people who are consuming a plant-based diet. Soy provides a complete protein profile and is low in fat.

It supports your heart health

Consuming soy can reduce the levels of bad cholesterol within your body, which is essential when it comes to fighting heart disease. Eating soy protein also can reduce your chances of developing heart issues as you get older, and it improves blood flow.  

It supports your bone health

Soy is great for bone health because it contains phytoestrogen, which helps you absorb calcium better. You’ll find a lot of soy protein supplements that include calcium, so you can increase your calcium intake and it’s a two-in-one benefit. Consuming this will help preserve bone strength and density, as well as help to fight osteoporosis.

It boosts your energy

If you’re exercising intensely or are an athlete, you’ll be supported with soy protein because it contains amino acids, which are the building blocks for your muscles and which can be converted to energy. Soy helps you with building muscles, and it helps you sustain your energy as you work hard to get lean muscles.

It can prevent cancer

Soy has genistein-phytochemicals, which studies have found to help lower risks of breast cancer and prostate cancer. This means consuming soy can be beneficial to both men and women. Additionally, soy protein genistein can prevent tumor cells from growing in the first place and stop cancer before it grows and worsens.
