This is excellent! What about the fat in nuts? vegetable fat, certainly not animal - but can go rancid, yes? what is the best way of storing nuts to prevent their going rancid?

because a brazil nut a day helps keep cancer away, but a friend who is very knowledgeable on cancer and carcinogens assures me that nuts can go rancid because of their high fat content, and when they are rancid, nuts are carcinogenic.

So I have been eating a brazil nut a day, but wondering how to prevent my stockpile of nuts from going off.....anyone know? At the moment I keep them in a sealed jar at room temperature. Should I be refrigerating them?
