Hi,
Just reding about the MSG,
I have had a "natural food" diet for about 4 years,and would be wary of eating out most places,when you have food allergies and are chemical sensitive the land of eating out is like a minefield!
Also with a tendency for hypoglycaemia,I carry healthy snacks with me seeds,fruit,chopped veg. & bring a packed lunch if I need to.If you always carry a little stash you won't be at the mercy of what's on offer in most places and if you buy or grow&prepare your own food,you know what's in it.It takes a little thought &preparation but our health is worth it.
