Recently I learned about a new program offered to Safeway Club Card members called FoodFlex. (For those of you unfamiliar with Safeway, it is a major grocery store.) Basically FoodFlex is a program that you enroll in (free) and you're able to see all your previous purchases that you've swiped your club card for. The program then analyzes all your purchases for nutrition based on USDA dietary guidelines.
While it does seem a bit big brother-ish, I've found it helpful and pretty darn cool. I was able to see that my husband and I may be purchasing items generally healthy and within the guidelines, but a little high in sodium. You can take it further by then asking the program to suggest food alternatives for the items that you may want to replace. Me, I am just going to really take a look at the sodium content of my potential purchases the next time I am shopping so I can find ways to cut it down a bit. I'll be checking back frequently to see how I'm doing. If you don't have a Safeway near you, check with your grocery store to see if they offer a similar program. From what I understand, this is the wave of the future for grocery stores.
