I love acidic foods. I have a whole lemon, skin and all, blended with an apple and vinegar and diluted with water every morning. That said, good tomatoes have a balance of sweetness and acidity, Cherry tomatoes tend to be sweeter than larger varieties. Remember, they are fruit. Acidic foods are good for helping break down food and maintaining a healthy gut flora. Your stomach acid is hydrochloric acid, much stronger than the acid found in food.No I could never eat raw tomatoes anyway. Weird...only cooked and like orange juice and that kind of acidic stuff bothers me.
