My forefathers didn't live that long though, did they? I think a lot of what makes us sicker now is pollution, antibiotics and pesticides in our food, avoiding whole food entirely, lack of moderation. I don't think I would say artificial sweeteners are bad, especially in moderation. 2 or 3 scoops during training, I think I will survive.
I don't mind fruit, but I also don't mind stevia or monk fruit. I prefer those actually.
When dieting down, I don't have a lot of room for fruit. When I see some I want, I love mangos, I eat it guilt free, as long as it fits my diet.
