There is no denying the importance of protein in your diet. Every cell in the human body relies on this essential macro-nutrient, and your hair and nails are made almost entirely from it.
Not only is protein necessary for building and repairing tissue, it is needed for your body to be able to manufacture the enzymes, hormones and the chemicals that it needs to be healthy.
Protein is both essential for your body's basic functioning and enormously beneficial for good health.
Eating a diet high in protein ensures that your body receives many health benefits, including faster recovery after exercise, a quicker build up of lean muscle, less hunger throughout the day and an easier ability to maintain a healthy weight.
But how much is too much? Are some forms of protein better than others?
In this article, we will seek the answers you are most curious about.

What Is Soy Protein?
Like other common forms of supplemental protein, soy protein has many positives and possible negatives for your health. The Soyfoods Association of America has defined soy protein isolates as the following:
Soy protein isolate can be found in a wide variety of health foods, ranging from protein bars, meal replacement shakes, bottled fruit drinks, meat substitutes and baked goods.
Soy protein isolate is a dry powder food ingredient that has been separated or isolated from the other components of the soybean, making it 90 to 95 percent protein and nearly carbohydrate and fat-free.
You can know that soy is an ingredient in your food if you see one of the following terms on the nutrition label: mono-diglyceride, soya, soja, yuba, TSF (textured soy flour), TSP (textured soy protein), TVP (textured vegetable protein) or MSG (monosodium glutamate).
Though not all textured vegetable protein comes from soy, a good amount of it does, while lecithin can be made from soy, eggs, or corn. To know for sure what is in your food, you can contact the manufacturer for a more detailed ingredients list.
The 2 Different Types
There are two main ways that soy protein is manufactured and sold:
Soy protein concentrate - formed when the fat content is taken out of soy beans, leaving a white flaky substance in its place.
After these flakes are given an ethanol extract to neutralize its pH levels, the substance is solid enough to be sold or used within prepared foods.
Because of the ethanol extraction, soy protein concentrate has a low level of isoflavine, (plant-derived estrogen) usually around 4% of the initial amount within the bean.
This makes soy protein concentrate a smart protein supplement for men that are worried about the side effects of consuming estrogen enhancers.
Soy Protein Isolate - After the formation of white flakes in soy, the concentrate is processed one more step through centrifugation that extracts the highest percentage of protein by weight.
The isoflavone levels remain higher (35-45%) than in soy protein concentrate because the step of ethanol extraction is skipped. Men that are concerned about estfrogen should avoid taking large amount of soy protein isolate.
Is Soy Protein Bad for You?
In recent years, these products have been getting a bad reputation. Many people believe that the majority of health claims for soy are actually false and the result of clever marketing schemes from food companies.
Some of their worst claims to the contrary are as follows:
You might be ready to swear off soy-based products for good after reading some of the purported negative health effects, but in truth the vast majority of soy products are not dangerous and are actually nutritionally beneficial instead.
Overall, soybeans have an impressive nutritional record. Each bean contains 30% carbohydrates (half of which are from fiber), 18% oil, 14% moisture, and a whopping 38% protein.
Research into the benefits of soy protein have shown that they can help lower your LDL cholesterol levels by as much as 5%.
While that might not seem like much, small differences in your cholesterol level can have a big impact on your overall health.
Simply choosing to consume organic soy-based products reduces your risk of being exposed to estrogen-damaging herbicides.
Likewise, here is a simple way to get rid of the negative hormone effects of soy and instead make it a safe and healthy food source: fermenting it.
The process of fermenting soy destroys the dangerous compounds it contains and makes it both safe and beneficial to eat.
Historically, Asian populations have eaten large amounts of fermented soy while being some of the healthiest and longest living people in the world.
Other evidence has shown that eating fermented soy can prevent osteoporosis, reduce your risk of various cancers, and prevent you from developing dementia.
Therefore, there is little to no risk for men and women to eat moderate amounts of soy protein isolate as part of a healthy, balanced diet.
In this way, soy protein can be viewed as a one more nutritional tool to help you meet your daily protein needs
Soy vs Whey Protein
Because whey and soy have key differences in regards to content and nutritional value, it's important to understand these differences so that you can make the right choice for you.
Whey protein is useful for maintaining bone health, putting on body mass (totalshape.com/supplements/weight-gainer-supplements), and repairing muscles after an intense strength workout, which makes it a smart choice for a post-workout snack.
Though whey protein provides you with a good balance of amino acids and minerals, it comes from dairy, anyone that is lactose intolerant will struggle to be able to digest it. Other negative side effects can include gas and bloating, cramps, headaches and general fatigue and exhaustion.

Soy protein is a great alternative protein source for anyone who is lactose intolerant or trying to cut down on their animal-based products. Though whey has long been considered the ideal protein for body building, the truth is that the key benefits of soy are almost equivalent.
Soy protein has been eaten by humans for over 5,000 years and is considered to be one of the highest quality plant-based proteins that nature provides. Each bean contains all the amino acids necessary for complete health.
The “feminizing” reputation of soy protein is largely unfounded, especially if you take the time to make sure your soy is sourced from high quality, organic sources.
The honest truth is that there is no right or wrong answer here. It's all about personal preference.
For best body building results, whey and soy protein should be used together.
Whey protein contains a large amount of branched chain amino acids, while soy protein has high levels of the amino acids arginine (a hormone that stimulates muscle formation) and glutamine (essential for workout recovery). Taken together, whey and soy protein supplements will keep you in peak physical condition.
THE BEST SOY PROTEIN POWDER IS?
Choosing the right protein supplement for your dietary needs can be tricky. However, soy protein is a great supplement choice for anyone that struggles to digest lactose and/or wants to avoid consuming animal products.
When organically sourced and eaten in moderation, soy protein is a smart choice for anyone aspiring to add extra protein to their diet.
