I like his rules for being sure you're getting real food in a store:
- never buy anything with more than 5 ingredients in it (more than that and likely the manufacturer (not the farmer!) is replacing some of what they've refined out of it)
- shop the outside perimeter of the store -- most of the manufactured stuff is in the center aisles of the store
- never buy anything that makes a health claim (does the humble carrot make a health claim? -- not!)
- get out of the supermarket whenever possible -- shop the farmers' market or your garden
- don't eat anything your great grandmother wouldn't recognize as food
- avoid foods whose ingredients are unfamiliar or unpronouncable
- avoid foods that include high-glucose corn syrup
I found out long ago that rearranging the food pyramid -- aim for ten servings of veggie/fruits a day, keep grains to five servings or less -- was the only way I could manage my weight and gain a feeling of well-being.
Variety is not only the spice of life, but it's the very stuff!
