I have about 1.5% of the overall net worth in precious metals. Bitcoin is simply enough to keep me interested, about $4K worth at current prices. But I am considering buying more as it successfully tested a double bottom around the $6K/coin level.
Regarding the food, I've taken a somewhat different approach on most of it:
a) I have a bunch of freeze dried meals, the type you use for overnight hikes. Mostly Mountain House brand. Since I hike, I can slowly rotate through the stock.
b) I have a bunch of basics: dried beans (Northern, Pinto, etc), pasta's, sugar, pop corn, etc. Some of this I acquired at the LDS facility, other from places like Costco. I took the 50# bags and made smaller amounts in Mylar sealed w/oxygen absorbents, which I then stored in bins and also in Gamma seal buckets. So, this isn't just a bunch of crappy high salt meals.
c) I do have some of the more traditional stuff which I will eventually either eat or more likely toss in another 10-20 years.
Basic food ingredients are re-markedly cheap in bulk. The biggest expense is animal proteins, of which I don't eat a lot of.
