Grocery store veggies are very old by the time they get to the store shelves. Zucchini, for instance, is inedible if you ask me. Once you've grown your own you realize just how unfresh all those "fresh" veggies really are. I don't know what they are treated with on the trucks and in the stores, but I've seen the rapid degradation once they hit my home too. I buy very little food in grocery stores now, and go there mostly for paper goods and pet supplies.

That poor woman probably has many other health problems too.
