One of the first mistakes my wife and I made when getting her on the diet was running to every health food store and health food aisle we could find. It's health food, so it must be healthy, right? No!
In fact, packaged foods in health food stores/aisles are stuffed with soy and "natural flavorings". Soy is the darling of the health food community. However, it is not your friend. Organic fruits and meats are still possible choices, but soups, stocks, sauces, and just about everything else in a box or jar probably has one of these culprits lurking in it.
Repeated failures can be demoralizing. Don't waste time, energy and spirit on the quest for miracles at the health food store. Put those resources to work gathering recipes and ingredients that you already know are safe. If you have some extra energy, put it to work in the kitchen instead of the grocery store.
