If you want to Whole30, eat paleo, avoid peppers or load up on meat and protein, that's your call. Everyone has the right to do what they think is best for their health.
Personally, I've always believed in eating everything in moderation. I'm not a vegetarian, but I try to eat vegan a few days a week to load up on veggies. I don't follow the Whole30 cook book, but I practice some of what it preaches in my day to day life.
Eat well, cook your own food, avoid too much fat and sugar and enjoy your meal. These are the food standards I try to live by.
So it is with a LARGE helping of crow in my mouth that I admit to having gone gluten free for the last 4 weeks.
