Since when are fruits so bad?

I'm getting tired of people knocking down fruits as if there was something wrong with a banana or an apple. I just don't get it. I notice this more from people who are struggling with their diet or trying to lose weight. I hear things like "Oh, I can't eat fruits, I'll gain weight". What?! You don't have a problem with fat-free processed cheese or drinking cow's breastmilk or eating a "light" meal at McD's but heaven-forbid you eat a mango or a banana. Luscious fruits and vegetables have existed before mankind, before the invention of sliced bread and fat-free this and that. Why is there something unnatural about natural foods and something natural about processed, naturally unnatural food (usually with ingredients you can't even pronounce let alone understand)? Eat your fruits separately and alone (unless with other fruits or certain greens). Eat them in abundance and ease up on the processed crap or better yet, eliminate it. You will start to understand that fruits are best for your body.

The next time someone tells me, "Ooh, I can't eat this apple or grapes. It'll make me gain weight. Fruits aren't good me", I'll just turn to him/her and say, "So what you're telling me is that God made a mistake when creating fruits and veggies? Instead, Kraft and Maple Leaf foods got it right?"

This is my short rant.
