The Washington Post was kind enough to mention the top five NOT health foods on the market. It's important to note that the sweeping condemnation isn't totally on the mark. For example:
Yeah most of them are from palm kernel oil and soy garbage. I wouldn't feed this stuff to a pet, and I wouldn't recommend it to you. If the ingredients have any more than 8 letters, it's probably not natural. Stick to Natural Food Bars or Larabars which are certified organic (and kosher!). Raw food bars are pretty good too.
Unless you feel drained, don't drink Gatorade or Powerade. Add some flavor to your water because taste helps your body feel more satisfied. The tounge and brain work against you with this one, so mix up the flavors with natural juices like lemon, lime, or other citrus slices of fruit in your water bottle. You can experiment with other fruits like pears and apples, but they take longer to infuse flavor.
Make sure that the ingredients have lots of actual whole flours and kernels. Check the fiber content as well. It should have at least 3-4 grams per serving.
