Do you believe that the general (fresh) food supply from your local grocer is spoiled, poisoned, or otherwise inedible compared to foods available at stores such as Whole Foods?
I’m genuinely curious. The opinions vary widely.
Fresh foods, local, organic, etc doesn't assure healthier foods. You have to look at the ingredients and sources. For me personally, I'd rather have canned foods that were fully ripened when harvested, without additives. Some of the stuff sold as "fresh" is treated for the market and harvested before it's ripened.
This is my personal approach, not the one others use. I shop by ingredients and only purchase foods from countries that have strict food standards and from US sources that are reputable for quality.
