Hmm, this is really interesting because I get headaches instantly when I eat raw red onion. Even if I eat lettuce or something else that's been with red onion and has traces on it, I get the instant headache. It's a real trigger food, yet totally natural. Give me anything with MSG in it and I'm fine, however, i avoid it like the plague. Like Laura mentions above, it is a hidden danger. Organic and fresh is the way forward.

Your walk looks lovely! I must say that there's nothing like a good walk to walk off the food regret feelings :)
