Best Soy Protein Powder Buyer's Guide
What is Soy Protein?
Soy protein is a supplement that comes from the soybean plant. Soy protein powders are a good alternative to standard protein supplements for those who are vegan, vegetarian, or lactose intolerant.
There are two main forms of soy protein that you can choose:
– Soy concentrates
– Soy isolates
As this review is discussing soy protein powders, soy isolates are what you can expect. Most protein powders use soy isolates due to their muscle growing properties. This is why people take protein powders to improve their muscle mass and tone their bodies.
A great benefit of soy protein powders is the fact that they often contain a range of amino acids that the body cannot produce on its own. This is why many people on a restrictive diet consume soy supplements to aid their health and wellbeing.
Soy protein powders contain a lot of protein. Many nutritionists consider soy to be a ‘complete protein’ that can benefit the body massively. Soy is mainly used in protein powders as an alternative to whey, which some people have to avoid due to their diet.
The Types of Soy Protein
There are two main ways that soy protein is manufactured and sold, as seen above.
- – Soy protein concentrate
This kind of soy protein is formed when the fat content is taken out of soybeans. This process will leave a white and flaky substance behind. In order to create soy protein concentrates, this flaky substance is given an ethanol extract to neutralize the pH levels. This process makes it solid enough for the soy protein to be sold as or used with prepared foods.
As it has undergone an ethanol extraction, soy protein concentrate has a low level of isoflavone which is plant-based estrogen. It usually contains around 4% of the original amount from the soybean.
This makes soy protein concentrate a great supplement for men who do not want to consume estrogen enhancers in case it has a negative effect on their body or wellbeing.
- – Soy protein isolate
In order to create soy protein isolate, the white flaky substance that comes from soybeans needs to go through another step of centrifugation. This will extract the highest levels of protein by weight.
Soy protein isolates have high levels of isoflavone because ethanol extraction is not performed to create this kind of protein. Soy protein isolates can contain around 35-45% of the plant-based estrogen. This makes isolates unsuitable for men who are concerned about taking estrogen enhancers.
Benefits Of Soy Protein
There are many benefits to using soy protein based on your dietary requirements.
- It is a good meat substitute
Meat is a great source of protein, but those who are vegan and vegetarian cannot consume it. Soy is considered to be a great meat substitute as it offers a complete protein and can be used in plant-based diets.
- It supports heart health
Soy protein can reduce LDL cholesterol levels in the body, which reduces the risk of heart conditions in the future. Soy is also great for vein health as it improves the conditions of your veins, allowing blood to flow to your heart easily.
- It improves bone health
Soy protein contains phytoestrogen, which makes it easier for the body to absorb calcium. Calcium is very important for healthy bones. Some soy proteins will come fortified with calcium, which can increase your calcium intake without consuming animal products.
Consuming more calcium can prevent reduced bone mass as well as fighting against osteoporosis. This condition causes your bones to thin and become brittle as you get older.
- It can improve energy levels
A lot of people take protein supplements before the gym to help give them energy so they can get a good workout in. Soy protein contains amino acids that can be used by the body and converted into energy that you can use to push yourself at the gym.
This makes it highly effective for those who want to tone and shape their bodies. Not only does it contribute to muscle growth and aids recovery after a workout, but it also gives you the energy to push yourself to get results.
- It can reduce the risk of cancer
Soy protein contains genistein-phytochemicals, which have been clinically proven to lower the risks of certain cancers, such as prostate and breast cancer. This means that soy is a great supplement for both men and women alike as it can improve everyone’s health.
It has been found that the genistein that is found in soy protein can actually stop tumor cells from growing full stop. This can effectively halt cancer in its track to prevent it from spreading or getting worse.
Soy Protein Vs. Whey Protein
Soy protein is an excellent alternative to whey protein for those who are on a plant-based diet or are lactose intolerant.
The reason why soy protein is such a good alternative is the fact that it is naturally high in protein, yet low in fat and carbohydrates. This makes it ideal for sports drinks and protein shakes to drink pre and post-workout.
Most soy protein shakes come in the form of soy isolates, which has a very high protein content of up to 95%. This is a great source of protein for those who are on a plant-based diet.
Whey protein, on the other hand, is made from cow’s milk. This makes it suitable for some vegetarians, but it is not suitable for vegans or those on a plant-based diet.
The reason whey protein is so effective is the fact that cow’s milk naturally contains just under 4% protein and 4% fat. Once the whey has been separated from the rest of the milk, which is required to make a protein powder, it is processed to remove excess fats, water, and carbs.
Both soy protein and whey protein are similar in their benefits and their protein content. Both of these types of protein also contain around nine amino acids that the body cannot develop on its own but are beneficial to your health.
The most important thing to consider is your own diet and beliefs. If you are vegan, plant-based, or lactose intolerant, then you can still get a great range of benefits from soy protein. You do not have to feel as though you are missing out when using soy protein, as the benefits are just the same in both.
Arguably, soy protein is better for your health as it can combat cancer and heart issues as we have previously discussed.
Other Plant-Based Protein To Consider
As well as using soy as a protein supplement, there is a range of other plant-based sources of protein that could benefit your workout and lifestyle. Many of these will be ingredients in vegan or plant-based shakes and meal replacements.
You could also try:
- Pea protein
- Brown rice protein
- Pumpkin seeds
- Flax seeds
- Hemp seeds or extract
A lot of these foods can be incorporated into your meals to increase the amount of protein you consume on a daily basis. They are also used in some vegan supplements due to the benefits they offer.
Soy protein is an excellent supplement for those who are vegan, plant-based, or lactose intolerant. It can provide a significant number of benefits that will not only improve your workout, but also your lifestyle. Soy protein can be used to increase your muscle mass, aid weight loss, and provide energy. Soy protein powders can also provide benefits elsewhere in your body as it has been proven to prevent cancer and support a healthy heart.
