Is Soy Milk Keto?
Soy milk is usually low in carbs and high in fat/protein…
So, does that mean soy milk is Keto? Can you add it to your Keto smoothies and coffee?
That’s exactly what I’m going to cover in this article.
The Bottom Line – Is Soy Milk Keto?
Soy milk is not Keto.
While unsweetened soy milk is low in carbs, that doesn’t mean it’s good for your health unfortunately.
There are healthy and unhealthy foods you can include in a keto diet. And while consuming unhealthy low-carb foods will put you into ketosis. It’s not the best way to look after your body in the long run.
So if you want to follow a healthy keto diet? And heal your body while you’re burning fat?
Leave soy milk out of your keto diet.
Why are we being so down on soy milk? Will it kick you out of ketosis if you drink soy milk?
Will Drinking Soy Milk Kick You Out Of Ketosis?
Let’s take a look at the macros…
Unsweetened soy milk has approx 2 grams of net carbs per serving (1 cup or 240 ml).
What are net carbs?
In general, they’re the carbohydrates in a food your body actually absorbs.
As Dr. David Perlmutter, M.D. explains, “Fiber, it turns out, is a form of carbohydrate, but is not a carbohydrate that has any effect on blood sugar or insulin response.”
Your body can’t absorb dietary fiber (and there’s 2 g of fiber in each serving of soy milk).
Which means you can subtract it from the total carbs listed on a nutrition label.
There are 4 grams of total carbs in soy milk, so subtract the 2 grams of fiber and you’ll get 2 grams of net carbs.
So, does soy milk affect your ketone levels?
Probably not. Given that soy milk is pretty low in carbs, it’s unlikely to affect your ketone level much if you’re just adding a small amount to shakes, smoothies, coffees or tea.
What’s Wrong with Soy and Soy Milk?
But, just because soy milk won’t kick you out of ketosis doesn’t mean it’s healthy for you!
Here are a few reasons why soy is bad for your health:
It’s highly processed
Processed foods can make our lives a lot easier, but when it comes to soy milk, it unfortunately creates a lot of problems.
The processing concentrates the most harmful parts of soybeans (AKA the parts that disrupt your hormones and irritate your gut).
The processing of soy milk also usually involves acid washing, neutralization solutions, and high heat. And if you’re worried about genetically modified foods or pesticides, then you should really beware of soy products! Almost all soybeans are genetically modified and pesticides levels are very high.
It could mess with your hormones
Soybeans contain phytoestrogens, which are a type of plant hormone which is similar to estrogen.
Clinical Nutritionist Christa Orecchio says, “Perhaps the most disturbing of soy’s ill effects on health has to do with its phytoestrogens, which can mimic the effects of the female hormone estrogen. These phytoestrogens have been found to have both beneficial and adverse effects on various human tissues.” She notes that drinking soy milk daily for one month is enough to alter a woman’s menstrual cycle.
And they confuse your body by binding to the same receptors as your own estrogen.
Which throws your hormonal system off balance…
And that affects everything from your immune system to your bodyweight.
This is more of a problem with soy milk than soybeans, because the plant hormones are more concentrated in soy milk.
It contains gut irritants
There are problematic substances in soy milk called phytates and lectins.
They’re found in many grains and legumes as part of the “defense system” which plants use to stop themselves being eaten.
Lectins cause trouble for your health because…
They may cause inflammation and leaky gut syndrome.
And in summary: they act like toxins in your body.
Phytates, or phytic acid, are just as troublesome…
Dr. Amy Myers, M.D. explains, “Phytic acid inhibits digestion and binds to certain minerals (specifically zinc, iron, and calcium) which are vital for our immune system to function properly, preventing their absorption.”
Which is why you’ll hear them referred to as “anti-nutrients”.
And again, these phytates and lectins more concentrated in soy milk than soybeans.
So, Is Soy Milk Keto?
In case you skipped to the end of the post without reading the rest of it, here’s the bottom line again:
Soy milk is not Keto.
A small amount of unsweetened soy milk isn’t going to kick you out of ketosis.
But it’s not great for your health to be drinking soy milk regularly.
There are other keto-friendly alternatives to dairy you can use instead (which are much more healthy).
Alternatives To Soy Milk
If you’re looking for a non-dairy milk to add to your coffee or morning smoothie…
Here are two healthier alternatives to soy milk:
1. COCONUT MILK
Coconut milk is made from coconut “meat” (the white part of a coconut).
And it’s full of healthy fats called medium-chain triglycerides.
What are the macros for coconut milk?
There are less than 1g net carbs in 1 serving (1 cup or 240ml) of unsweetened coconut milk.
So it’s a healthy low carb alternative to soy milk.
NOTE: The nutritional data above is for cartons of coconut milk (which is approx. 45 calories per 1 cup serving). You will also find cans of coconut milk which contain higher concentrations of coconut cream in them. They will contain more fat and slightly more carbs per 1 cup serving.
2. ALMOND MILK
Almond milk is easy to make at home or to purchase in various grocery or health food stores (in the US).
If you want to try making it at home, then soak almonds in water overnight. You can soak them for up to two days for ultra-creamy milk.
Then, drain and rinse the almonds, grind them with fresh water using either a blender or food processor.
Lastly, strain the milk to get rid of the almond pieces and store in the fridge. Your milk will last for a few days.
What about the macros for almond milk?
Unsweetened almond milk contains just under 1g of net carbs…
That’s why almond milk is another healthy, low-carb alternative to soy milk.
IMPORTANT: If you’re buying coconut milk or almond milk, do make sure it’s unsweetened!
What About Other Soy Products? Is Tofu, Edamame, Soy Sauce Keto?
Soy milk is out, but what about other soy products? Are they keto-friendly?
We cover tofu, soy protein powder, edamame, and soy sauce below.
Is Tofu Keto?
Tofu is actually made from soy milk – which may come as a surprise!
And that means you should avoid tofu for health reasons, even if it only contains 0-1g of net carbs per 100g serving.
It’s a very concentrated form of soy, so the same problems we listed above for soy milk apply here.
Is Soy Protein Powder Keto?
Soy protein powder is made from dried, defatted and dehydrated soybeans.
Again, it’s highly processed and given the number of other much healthier ways to increase your protein intake (like eating a steak!), it’s best to avoid soy protein powder on Keto.
Are Edamame beans Keto?
Edamame beans are young soybeans in the pod.
While processed soy products can be problematic for your long-term health, whole or fermented soy products can actually be beneficial for your health.
So, edamame beans are keto-friendly in small amounts.
There’s 5g net carbs per 100g of edamame beans, so you definitely won’t want to eat too many.
Is Soy Sauce Keto?
It’s actually because most soy sauce contains gluten.
Traditionally, soy sauce is made simply by fermenting soybeans. And fermentation gets rid of most of the problems with soybeans.
However, nowadays, wheat is usually added to the soybeans. But you can still find wheat-free and gluten-free soy sauce.
Look for brands labeled gluten-free tamari sauce – these are keto-friendly.
And if you want to go completely soy-free…then go for coconut aminos
Coconut aminos are a naturally soy-free and gluten-free soy sauce alternative.
They contain minerals, vitamins, and 17 different amino acids.
And they have a rich flavor which is a mix of savory and sweet.
So…Soy Products…Yay or Nay For Keto?
The general rule is to avoid soy products where possible with the exception of whole or fermented soy.
Don’t make soy milk or tofu a regular part of your Keto diet, but add in gluten-free tamari sauce and edamame beans for more variation and flavor.
So, don’t just look at the carb count in a food. Figure out how that food affects your body, mind, and health long-term.
That’s the solution for ensuring you get healthy and stay healthy life-long.
