Everything You Should Know About Soy Protein

Soy protein is an isolate or concentrates sourced from soybean protein. Some of its examples include soy isolates, soy protein concentrate, and soy flour. All these are examples of protein-rich products made from defatted and dehulled soybeans. Just like other types of protein supplements, these too have their pros and cons for your health.

Nowadays, you can find soy protein concentrate in a wide range of health foods. Some of the common foods that contain soy protein are protein bars, bottled fruit drinks, baked products, meal replacement shakes, and meat alternatives. If you see some terms such as TSP, TSF, MSP, and TVP on the food labels, it is a sign that they contain soy protein.

Types of Soy Protein

Before you buy and use soy protein, you need to ensure you get the right type. The main types are soy isolate and concentrate.

Soy protein concentrate is processed from soybeans. Ideally, the fat is removed from soybeans. Usually, the alcohol extraction method is used to neutralize the pH levels. This makes it possible to use soy protein concentrate in food preparation. Since ethanol is used, it has low levels of plant-based estrogen. If you are concerned about the effects of eating natural estrogen enhancers, this is the right protein supplement to take.

Soy protein isolate is made by further processing the concentrate. Ideally, the concentrate undergoes centrifugation to ensure the finished product has the highest protein content. Nevertheless, the plant-based estrogen remains higher than in the concentrate because the ethanol extraction procedure is not used. This explains why the isolate is not recommended for men.

Should You Use Soy Protein?

The truth is that soy protein has many health benefits. It is recommended for people of any age and it offers various health benefits, such as muscle building and weight loss. However, some soy protein brands have a negative reputation. This is because many health claims are false and devised by food companies as part of their marketing gimmicks.

You should note that soybeans provide great nutritional value. For instance, each soybean contains 38% protein, 18% oil, 30% carbohydrates, and 14% water. Studies done on soy protein concentrates have shown that they help improve one’s health by lowering bad cholesterol levels. This explains why you should consume organic soy protein powder.

If you are concerned about the negative effects of soy, you should consider fermenting it. This will make it a healthy and safe food source. The fermentation process helps to destroy the harmful compounds in soy. Various studies have revealed that consuming soy can help prevent osteoporosis, reduce the risk of cancer, and prevent dementia.


Consuming soy protein powder has minimal risk to your health. Nevertheless, you should moderate your consumption of soy isolate. The truth is that soy protein powder is an important nutritional tool that can help you to achieve your protein requirements. Moreover, you can use it to achieve your weight loss goals. If you are intolerant to lactose, soy protein is the best alternative for you. It will help you cut down your intake of animal-based products.
