Do you often feel tired, bloated, or suffer from unexplained pain? You may blame stress or poor diet, but have you considered lactose? This often underestimated intolerance can manifest itself in many ways. Here are eight signs you should pay attention to to understand if your body is trying to warn you.

Mouth ulcers: small ulcers that could tell a lot
Do you regularly suffer from mouth ulcers? These small, painful oral lesions could be linked to your consumption of dairy products. Certain proteins in cow’s milk are suspected of triggering an immune reaction, promoting their appearance.

Solution: Try a dairy-free diet for a few weeks and see if your mouth ulcers diminish. Opt for plant-based alternatives like oat or almond milk.
