Since going carnivore about 2 years ago, my shopping list has shrunk dramatically. Aside from grocery shopping taking less time, another benefit is that I can mentally track food prices more easily...there's just so few foods to track.
My favorite food is BEEF. I wrote a post on how most people eating the carnivore diet tend to converge on beef It seems like all carnivores converge on this one favorite food.
And I'll be damned - the price of beef has jumped dramatically, over the time that I've been carnivore. Just tracking the lowest cost ground beef, going off sale prices at all the local groceries, I'd say it's gone up at least 50%, maybe more like 75%. Now, even with the best sales at the restaurant supply places, you can't get beef for $4/lb anymore. The average good sale price at an average grocery is around $5/lb.
Eggs were really high a while back, and have since come down again. I really hope the same will happen to beef. I'm not sure that it's the same type of situation, though - I know that a lot of chickens were killed off because of supposed bird flu concerns.
In case anyone thinks that buying beef from the farmer gets you a better deal, think again. Maybe that used to be the case, but it ends up being much more a gourmet experience, as opposed to a bargain experience.
