Will non-dairy yogurt provide a similar probiotic benefit to “natural” yogurt?

Q: John – I have a lactose problem, but I still want the probiotic help that comes in a good natural yogurt.  Is there a soy yogurt that has similar probiotic benefit or do I have to stick with the real stuff?

A: Alisa – The short answer is yes, there are several non-dairy yogurts available that will offer probiotic benefits equivalent to dairy-based yogurt. In fact, for those who are lactose intolerant the non-dairy yogurts may have more noticeable benefits since you won’t be contending with lactose maldigestion symptoms from the yogurt too. I have included some soy yogurt options below and will also go into a bit more detail on this topic and address what a “natural yogurt” could be.

Probiotics Improve Digestion in Dairy or Non-Dairy Yogurt

It is not uncommon for someone with lactose intolerance to be tolerant of good quality dairy yogurt. This is because certain strains of probiotics have been found to aid in the digestion of lactose.

Though L. acidophilus has long been recognized as the digestion hero, it was actually found in studies to have very little effect on the digestion of lactose. But another member of the Lactobacillus family, L. bulgaricus showed improvements for the hydrogen breath test (a basic lactose intolerance test) and symptoms. (Source: American Journal of Clinical Nutrition) For more information on lactose intolerance and the tests available, see Go Dairy Free: The Guide and Cookbook.

L. bulgaricus is commonly used as a starter for yogurts, both dairy and non-dairy, so it is fairly easy to find. Also, based on the studies I read, it looks like you will get the same benefits from this probiotic no matter the medium (whether in a cow’s milk yogurt or a soy yogurt). The benefits of probiotics are created in the process of fermentation, so the medium is not necessarily what is important. This is why Kimchi, a fermented vegetable Korean dish, has been used for centuries as a tummy-tamer at meals.

Probiotic Preservation: Why Store-Bought Isn’t Always Best

What is important is the level of live active cultures in the finished product (those not destroyed in the production of the yogurt), and how well it is stored to avoid destruction of these cultures before they are able to reach your gut (chilled mediums are usually best for both supplements and foods).

Keep in mind, most commercial yogurts are pasteurized (killing off many of the live active cultures) and have probiotics added in after the fact. These may not have the same gut benefits as the cultures from the original fermentation. Check with the yogurt manufacturer to find out their processes and the live active cultures in their finished products.

Better yet, make your own yogurt at home! The definition of a “natural yogurt” can vary since it is not a regulated term – it may simply be one made with all natural ingredients, Greek-style yogurt, yogurt made from a prior batch of yogurt, or a plain unsweetened yogurt. The best way to qualify your non-dairy yogurt as “natural” by any of these standards is to make it yourself. You can easily prepare a batch of yogurt with your own makeshift apparatus or by using a relatively inexpensive yogurt maker.

Go Dairy Free: The Guide and Cookbook offers recipes for homemade Soy Yogurt, Coconut Yogurt, and Cashew Yogurt (the latter two also being soy-free options) and full instructions.

The Best Store-Bought Soy Yogurts Available

My favorite soy yogurt brand, Whole Soy & Co, went out of business. I’m still waiting for another option to emerge that is as healthy as that brand was! Nancy’s also discontinued their Organic Cultured Soy Yogurt, but they have replaced it with dairy-free Oat Milk Yogurt. Luckily, there are still a couple great brands on the market:

• Silk Dairy-Free Yogurt made with Soy – This is a delicious yogurt that’s very close to yogurts like Yoplait in taste and consistency. However, they don’t have an unsweetened version and the flavors are relatively high in sugars (like Yoplait!).
• Stonyfield Organic O’Soy Yogurt – There was a big uproar when people discovered this soy yogurt brand wasn’t actually dairy-free. They do now label their product as vegan, but I would still check on the growth medium if severe milk allergies are a concern since they also make dairy  yogurt.

The above mentioned products can be found at Whole Foods and other natural food stores. However, I have also seen each of these brands in the natural food aisles (refrigerated) of my local mega-grocer. They are each widely distributed in the United States.

Not into soy? There are almond, coconut and many other types of dairy-free yogurt now available! See our Substitutes Review Section for information on several soy-free, dairy-free yogurt brands.
