I’m always wary of claims that various foods can cure anything or even improve health. The science of how what we eats impacts us is still too primitive and too general for my taste. Case-in-point is this story I read recently about black pepper.
For someone trying to cut salt from their diets, pepper becomes a go-to flavoring It’s usually available when eating out, for one, and it’s tasty without being spicy hot which I tend to shy away from. So I’m using more pepper in my cooking.
But this Time article says black pepper could aid digestion and have other health benefits as well. It also can counter-act some carcinogens in charred beef (barbecue fans take note).
I hope all that is true, but for now, I’ll just use black pepper because I like the taste. If you have a local spice shop, ask for a salt-free mixture of various peppers as I’ve done to get some variety of flavor.
