@TeddixatIn an ideal world, we would all eat healthy foods we grew ourselves and prepared in our own kitchens, but the likelihood of that happening any time soon is probably near zero. I do not blame the messenger - people can buy Nutrisystem and every other diet product in just about every supermarket, from a gazillion online and in print sources, etc.
I do know that when I was carrying 50-80 excess pounds, the last thing I worried about when I decided once again to try to lose weight was preservatives. After all, there wasn't much healthy that I was eating anyway.
I did try Nurtrisystem once and I did lose some weight. Just didn't stick with it because I didn't like the taste, especially of the breakfast foods and the snacks. But -- that was more than 10 years ago - no idea what the current products are like, but I still probably would be less concerned with the preservatives (except the sodium related) than the taste. I doubt we can feed the world population at the size it now exists without today's science.
