What's your beef with lactose? I think we should be a tolerant society. What did lactose ever do to you?
Sometimes the body stops making certain enzymes as a person ages.
Good luck dealing with this
I'd near end my life if I couldn't have pizza comfortably. There's medications to aid this kind of problem thankfully.
If you stop consuming milk/milk products, your body stops making the lactase enzyme to break down the lactose.
I think that happened to my brother, all of a sudden he couldn't drink cow milk and my mom got him goat milk, now he still drinks milk and eats cheese but then he has issues hahaha
