That is a good suggestion if you have been trying to eat healthy for a long time. At this time, I have more of a feel of what is in what I eat than I had when I started but I don't 'just know', automatically. I started my own list of of nutrients when I first decided to cure my issues with food. I think I will organize it in an easier to use form and continuing tracking manually. It is about 6 pages long at this point and labeled with brand names.
I think I need to look at ingredient lists, too. It is the only place sugar alchohols show up, and I believe they cause interference with the gut biome. (I just had bowel surgery) I read a recent article that said the FDA had just banned some pesticide with nerve agents that was being used on tomatoes, which is one of my mainstays. The fda has known of the problem for 20 years or more. I also read an article that said, for some people, folic acid supplementation may save you from spinal bifida but may cause other serious problems that don't arise with folate. That's like saying an orange is just as good as a Vitamin C tablet. I don't think so. There is a lot of other things in an orange that go together to make them healthy. Sorry for the rant. I will keep working at it.
