> a deficiency in any nutrient is less to do with a lack of it in the diet and more to do with the body's ability/willingness to absorb and utilise it I too have come to realise this. Many times when I have been eating well, good quality food with plenty of variety, I catch a heavy cold that puts me out of action for at least a couple of days. Other times I have eaten like crap for weeks at a time, living off of pizza and fast food, skipping meals, and been around sick people and still don't catch anything. I have seen this pattern repeat over and over throughout my life.
