I've been 99.99999999% (save accidental ingestion) grain and soy free for something like six months now. This includes all grain and soy derived products and additives. Have not had any real colds, although there are lots going around here. I eat an extra grapefruit (not paleo-orthodox, I know) if I feel any hint of a bug. That and a good night's sleep seems to knock anything out, so far. This is a BIG contrast to my prior experience. I used to get every darn bug in the universe, as bad as anyone. I wanted to ask about skin tone. Since I cut out grains and grain products altogether, I feel like my skin tone has gotten darker all over. Anyone else have this kind of experience? I like it; but I find it curious.
