I don't think the nutrients in our food sources aren't removed during processing unless you are talking about those that are cooked, canned, etc - yes! But fresh ones wouldn't fall into that category - however because our soils are so depleted from the vital nutrients it's necessary to get them elsewhere. Organic usually only means that pesticides are used on them. Meats, unless they state otherwise, are most definitely pumped up with hormones and antibiotics! Then you have gene altered produce that comes into play (you can usually tell if something has been altered when you drive in the countryside and look at fields of corn, etc - if there is a sign posting a # or similar). Just like many of our tomatoes grown - are hybridized so that the skin is tougher so machines won't damage them in picking process. It's always better to get local produce that's not produced in such a way. And if possible - DON'T buy canned vegetables - buy fresh or frozen not precooked.
Defnitely like skincareteacher said - get off prescription meds if you can or find a natural solution - it's the synthetics that are killing us! Also look into homeopathic ways.
