I find that I often feel bloated and very tired if I eat too much pasta/bread based meals
You may be developing a sensitivity to wheat. Some medics nowadays would advise you to cut down your intake to reduce the risk of developing a full allergy.
Wheat allergy is rising sharply among the population. No-one seems to know why. It may be to do with the fact that the food industry pumps wheat into just about every food product these days, as a filler and as a water absorber to pump up the weight (and profit). You'll even find it in uncooked ham, whole chickens - all sorts of places you wouldn't imagine. Add to that the popularity of pasta, pizza, burgers etc and it's plain the average intake of wheat is far above historical levels.
Fruits and nuts (not "Fruit & Nut"!) are all you need - but not too many peanuts, for the same reason as above.
