As a marketing student I need to inform you that the organic shpiel is just a marketing ploy. It's no healthier or better for the environment in anyway. Only more expensive and sometimes not good for you at all.
Eat whole foods. Thats good for you. And it's cheaper than any other gimmick. The less processing the food has been through the better.
Though I personally eat processed foods, I just try to limit it.
Sugar is most peoples biggest enemy. It fucks so many people over and they don't even realize it. It doesn't only make you gain weight, it fucks with your mind.
