For decades people living in industrialized countries have abandoned healthy food, the stuff with natural nutrients, vitamins and minerals for chemically / genetically modified foods, the stuff that looks good but is void of all the good stuff important for our body.
With the industrial mindset to make everything “faster and cheaper” scientists naively but intentionally found a way to grown plants and crops by altering the soil composition (the source of all the nutrients).
And so what we see today in most grocery stores or supermarkets and pick out as greens are no longer the type of greens that can positively impact our body, but rather onees devoid of any value.
This is a great video clip that explains why what we eat today is no longer healthy and why we need to find a way to solve this problem FAST.
Plant your own greens if you can. http://www.youtube.com/watch?v=4Z1C8VKtLwY&feature=related
