And as usual, Dr. Andrew Weil has some fantastic advice on his website about food safety. If you've got the time, browse his site. You'll be glad you did!
I am a firm believer that poor and inadequate nutrition is at or near the root of most health problems found today. It isn't always easy or economical to eat whole foods, or at the very least foods as close to their natural state as possible, but it can be done with planning, patience, and a ton of perserverance. Eating healthy shouldn't be so complicated. It can save your life. I have to drive over 50 miles one way to the nearest Whole Foods Market or Greenlife Grocery, and with current fuel prices that trip costs me $30 just for gas. Not what I consider economical. Luckily there are alternatives. Local produce stands generally offer seasonal, locally grown foods at reasonable prices, and some even accept special farm market senior citizen and WIC coupons and food stamps, so if you have one in your area, there's really no excuse for not eating well, at least some of the time. Do a little research, ask around, or visit your local county extension office and find out if there are farmers in your area who sell at markets or roadside stands. And if you have a patch of dirt in your yard big enough to plant a cabbage head in, give it a try. You might stumble upon something that will sustain you physically, mentally and emotionally for the rest of your life. A garden!
