Micronutrients & recovery
Fermented dairy products can alleviate lactose intolerance symptoms by degrading lactose through the action of lactase produced by lactic acid bacteria.
If you are lactose intolerant, try eating yogurt or kefir. The bacteria in these foods break down most of the lactose, making them easier to digest than regular milk. Start with small amounts to see how your body reacts.
GoodSupportsHIGH confidence
In contrast, fermented dairy foods, such as yoghurt, can be consumed with fewer or no symptoms, since LAB used to make yoghurt produce lactase that can achieve lactose degradation and thereby reduce symptoms
Why this rating
The paper cites multiple studies and general consensus on lactose degradation in fermented dairy.

- Fermentation of milk by specific microbial consortia (e.g., Lactobacillus, Streptococcus) produces bioactive peptides and increases antioxidant activity, which may exert blood pressure-lowering effects and protect against oxidative damage.Moderate
- Fermentation of grain-based products (e.g., sourdough, tempeh) reduces FODMAPs and increases the bioavailability of phenolic compounds and vitamins, potentially offering anti-diabetic and antioxidant benefits.Moderate
