For the record, I do supplement the trail mix I get from Sam's Club with craisins, more cashews, and dry roasted peanuts.
When I searched the Internet for trail mix articles, I found that some strongly railed against both M&M's and craisins in many trail mixes as unreasonable sources of sugar. My own results seem to contradict these reports. Sometimes a little sugar keeps me from eating a lot of sugar.
Finding go-to low-calorie snacks is vital to a successful weight-loss program. As a non-professional in nutritian and dietary matters, I highly recommend the perfect food.
