Re: Why can't we eat fruits and vegetables together?
I don't know what your mother may have heard, but lots of folks eat fruit and vegetables together at mealtimes with no problems whatsoever. I usually have a banana for dessert after a dinner which includes lots of veggies. My tomato sauce, which includes chopped up fresh tomatoes (called a fruit by botanists but a veggie by cooks) when they are in season, is also chock-a-block full of other chopped up veggies, with more veggies on the side. My husband was practicing his sushi skills last night and one of his yummy sushi varieties was a roll with nori (a sheet of dried seaweed -- a veggie) wrapped around rice with white peaches (a fruit) in the middle.
My husband and I don't have nutritional deficiencies -- except for Vitamin D which we can't get from the sunshine which we don't have any of in this dreary north of Europe, but which has nothing to do with food combinations at dinnertime.
Perhaps someone else can enlighten us as to what the problem is supposed to be?
