This blog post will be discussing some of the soy milk benefits, what is soy milk, and how to make soy milk quickly and easily at home with a simple homemade soy milk recipe. I’ve also included some ways to flavor and vary your soy milk, for different flavor palettes.

Soy foods and soy products have gotten a lot of flack over the years, and there’s always been this question around it of is it good for you, isn’t it. Especially as a mostly GMO product ( eat organic soy to avoid GMOs). However, I’ve never had an issue with soy products and know many who’d agree, so I won’t go too much into that here.

In fact, if you do want to read more about soybeans and the debate over their pros and cons etc. then here are a few links you might like to articles that can explain things a lot better than I do. Such as this article in GoodHouseKeeping, or on Health Line.
In fact, my takeaway sentence from Health Line is the only thing I’ll share here: Which states that while animal studies have shown that soy can negatively impact thyroid function, male hormones, and even breast cancer. The same cannot be said for the human studies that have been conducted.

So, as far as I’m concerned – Soy (particularly the most un-processed versions using soybeans), is perfectly healthy to eat in moderation.

Over the last decade or so, soy milk has become one of the most popular lactose-free, dairy-free milk options available. This is primarily due to the high protein levels of soybeans, meaning this milk can compare nutritionally to cows milk in ways that certain other dairy-free milk options cannot. In fact, soy-based milk is healthier in many ways, which I’ll go into in more detail below.

So, What Is Soy Milk, and why make it at home?

Soy milk is made when you blend the soybeans with water to create a creamy, milk-like liquid. During the process, the insoluble fiber from soybeans separates for the resulting liquid, so you’re left with smooth milk.

When buying store-bought soy milk (like many plant-based milks), you will often find unnecessary additives, preservatives, and thickeners. Unfortunately, many of these ingredients can wreak havoc on your gut – especially if you’re consuming them in large quantities. Luckily, by making homemade soy milk, you’re able to be in control of what goes into your milk.

Homemade soy milk can also work out a lot more cost-effective than store-bought varieties – Especially if buying the beans in bulk. From a quick online check, I found a 5kg (0.79 stone) bag for just £12 (around $15). Doing the maths, this means that a single cup of homemade soy milk can cost you as little as around 10 cents when following this recipe.

It’s also possible to fortify your dairy-free milk further with the use of a vegan collagen powder mixed into the water. And, if you consume animal products, then bone broth can be very beneficial to the gut.

Soy Milk Benefits

As I’ve already stated above, much of the controversy surrounding soy products seem to be linked with animal studies. Whereas human studies have largely disproved these in many ways and have given us several soy health benefits.

Currently, science doesn’t fully understand soy, so these facts and studies could still change. However, for now, I’m happy to eat low processed soy foods/ products in moderation and have personally never seen any adverse health risks from my soy consumption. The same can be said for all of my soy eating friends.

One of the best pros associated with soy milk is how it compares to dairy milk whereas an 8oz portion of whole cows milk contains 12g respectively of carbs and sugars and 8g of protein and fat. Unsweetened Soy milk contains 4g carbs, 1g sugars, 4g fat, and 7g protein. It also contains fewer calories ( almost halved, in some cases) of whole milk and equal calories to 1% milk.

In fact, soy contains all nine essential amino acids (fatty acids), while being a fantastic source of protein and balanced with carbohydrates and fats.

As plant-based milk, soy milk is also naturally low in saturated fat and cholesterol-free, which means that it is a great milk option for weight management, weight loss, and heart health.

Soy milk is also naturally lactose-free, so a great option for those with lactose intolerance.

Homemade soy milk is also a good source of a variety of vitamins and minerals including Vitamin A and potassium.

Soy milk also contains ‘isoflavones’, with research suggesting that these are antioxidants. Thus, they reduce inflammation and even have anti-cancerous properties to reduce the risk of certain diseases and cancers.

Some studies even show that consuming soy protein daily may help reduce harmful LDL cholesterol levels in the body.

How To Make Soy Milk

Making soy milk is a fairly simple process, using just two ingredients – soybeans and water.

The first thing you need to do is soak your soybeans. Soak the beans in water for at least 6 hours, or overnight.

Note* I’ve read that if you have issues digesting beans then adding a splash of apple cider vinegar to your beans while they are soaking will help leech out phytic acid content, without affecting the flavor.

You’ll notice that soaked soybeans will expand between 2-3 times in size.

Once they are soaked, you can then optionally peel the beans. This isn’t 100% necessary, although it will help to blend smoother homemade soy milk and only adds a couple of extra minutes of prep time to the recipe. After soaking the beans, the skins will come off very easily.

Next, add the soaked beans into a high-speed processor/blender for just 10-15 seconds to break down the seeds slightly.

Add the cups of water and blend again until smooth and creamy.

You then do an initial strain into a large pot. This will reduce the risk of any of the beans burning to the bottom of the pot. However, I transfer the entire mixture into the saucepan and bring to a boil over medium heat as I stand over the pot during this process and stir often.

When the mixture starts boiling, continue to cook for 3-4 minutes.

While boiling, remove the foam that starts floating on top. You want to try and skim as much of this foam as you can.

Reduce the heat and simmer for 15-20 minutes, occasionally stirring to make sure nothing is sticking to the bottom of the pan.

Turn the heat off and leave to cool down for a few minutes. Then pour the milky liquid in a bowl through a nut milk bag.

Squeeze or press down the nut milk bag, so all the liquid drains into the bowl.

This can then be transferred to a bottle.

Store your homemade soy milk in the fridge for 3-5 days. If it begins to smell/taste sour, then it is past its best.

You can also freeze soy milk for 3-6 months. However, this can slightly affect the texture of the milk (although not the nutrition).

Homemade Soy Milk Recipe Variations

I always keep my homemade dairy-free milk recipes down to the bare minimum. However, plain soy milk isn’t really to everyone’s taste buds as it’s quite a strong flavor. To combat this, and in general just jazz up this soy milk recipe, you have a few flavor options.

The first thing to address is sweetness. I like to keep these recipes refined sugar-free and suggest using Medjool dates or maple syrup to sweeten your homemade soy milk naturally.

You can also add a variety of spices/ add-ins including homemade vanilla extract, cinnamon, cacao powder, etc.

For the full plethora of dairy-free homemade milk, feel free to browse through the DIY section of my blog or search ‘milk‘ in the search bar for options including rice, flaxseed, almonds, oats, pistachio, etc.
