I would like to point out that there is a zinc taste test that is administered when performing a functional analysis. Some liquid zinc is drunk, and the results are: it tastes terrible - means you have a good amount of zinc in you. Then down the line until someone says they taste just water, or you could say they have lost their Ave asense of taste - as far as this one element is concerned. So consider that when you have a cold you also cannot taste or smell well. I recommend taking therapeutic doses of zinc for anyone whose sense of taste or smell is deficient. Calm down and take zinc daily!!
