What is soy protein powder?

Very soon, we’re going to share our reviews of a whole range of products so that you can find the best soy protein powder for you. But first, we thought we would answer any questions that you might have about soy protein, starting by ‘what is it?’. Here we go!

Soy protein originates from the soya bean, a staple in most vegan diets due to its high protein content. Soy protein powder is made by processing soybeans until they become soy protein isolate.

Unsure of how to eat soy protein powder? As with other kinds of protein powder, it can be used to make protein shakes or added into meals to increase your protein intake.

This protein is a complete protein which means it has all of the essential amino acids (EAA) that your body requires.

Amino acids are vital for your body to grow and function correctly. Nine of the amino acids cannot be made within the body. These are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine.

Because your body can’t make these amino acids, they must come from food. Amino acids are part of many animal protein foods like eggs and meat, but also some plant-based food staples such as soy, quinoa, and buckwheat. Hence, soy protein is vital for people who follow a plant based diet as they cannot eat animal products!

Now you know what soya protein is and why it is an important part of your diet (especially if you’re a vegan!), let’s find out if soy is actually better than whey!

What is better soy or whey protein powder?

When it comes to the ‘best kind of protein’, there’s no one size fits all approach! It really does depend on your individual goals, preferences, and dietary requirements.

Even within the categories ‘whey’ and ‘soy’, the quality of protein powders will still differ from brand to brand.

There is a much larger selection to choose from when it comes to whey protein so you can be spoilt for choice. Whey protein tends to be smoother and has a creamier texture as you drink them. Meanwhile, soy protein has a slightly more grainy texture, but again, it’s down to personal preference.

However, if you’re looking to cut back on dairy, or you are lactose intolerant or vegan, your best bet would be to go for soy protein as you will still get the same amount of protein per serving as the whey protein.

If you do not know how to use soy protein powder, don’t worry, you can still use it like regular whey protein and drink it as part of a shake before or after your workout.

Now you know what it is, let’s find out where to buy soy protein powder!

How much soy protein is too much?

Like with most foods you eat, everything in your diet needs to be varied and balanced. As mentioned before, having soy protein is a great way to cut back on dairy and meat.

Unsure of how many grams of soy protein to consume per day? According to Healthline, if you eat or drink 25 grams of soy protein per day, which is the average amount of protein per shake, it’ll help reduce the bad cholesterol (LDL) by up to 3%.

You don’t have to worry and think ‘how much soy protein per day should I eat and drink?’, as you’d have to consume an awful lot of this protein powder to see any serious side effects. At the same time, even having the odd soy protein shake will have some benefit and will help you to swap meat and dairy out of your diet.

What are the drawbacks of soy protein?

With all food and drink, there will be people asking ‘why is soy protein bad for you?’ One concern about soy is that it is thought to affect thyroid function. However, in a study by Messina et al, eating soy protein was found to have very mild or no thyroid function effects.

Another reason that some people steer away from soy protein is because of its phytoestrogen content. If you didn’t know, phytoestrogens are chemical compounds with estrogen properties that help bind to your body. If you eat foods that contain high amounts of phytoestrogen content, it could disrupt your natural hormone levels.

However, the initial process of making soy protein often means that a significant portion of phytoestrogen is removed by rinsing the soybeans with alcohol and water.

So to anybody asking ‘why is soy protein bad for you?’, the answer is that soy is safe for most people and isn’t bad at all! The potential drawbacks that have been listed above is for soy as a whole rather than soy protein.

Before you go!

The soy protein powders listed above are the best 15 you can find online! Each product has its selling points, but we know you will love whichever one you choose.

Compared to other vegan protein sources, drinking soy protein blows the competition out of the water when it comes to the amount of protein you receive from each shake.
