Yes, but I haven't figured out the details yet. In general, anything in a package or a can bothers me. I don't know if it is the preservatives or some other food additive that bothers me, but something does.

Anything with MSG is really bad, it makes my legs give out on me.

When I eat meals made from fresh food my MG gets a little better. It seems like nuts and green leafy vegetables make me feel best so I have started carrying around various nuts to snack on when I feel weak, and I am in the process of learning to cook with more green stuff. I can feel an energy boost when I eat sunflower and pumpkin seeds. Makes me wonder if I have some kind of mineral deficiency.

Like I said, I haven't really figured this out but I know that what I eat makes a big difference in how I feel.

The best thing is to keep a record of what you eat for a while combined with how you feel and see what works for you.

I hope this helps.
