I eat meat but having learnt how bad for the environment this is, I am making a huge effort to eat vegan and veggie. Since I have swapped from meat to vegan my skin is clearer, I sleep better, I am less stressed and I breathe easier (prior to this I struggled to breathe through my nose at night times).... It has made a Huge difference.
I think a big part is swapping cows milk to oat and almond milk. Oat milk in coffee does not curdle unlike soya milk which sometimes does.
My advise to l is TRY IT and see after about 10 days if it has made a difference to you.
