I believe it, but there will always be that problem where a head of lettuce was $8 and an entire Big Mac combo was $12.
I don't think it's possible to really eat healthy anymore, unless you are growing it, or slaughtering it yourself, or you have some closer understanding/connection to its source, such as a local farm & butcher, farmers market, etc.
It's really not that hard to eat healthy, you just have to avoid 9 out of 10 aisles.
The grandmother I knew was diabetic after a lifetime of soda and Mars bars. The grandfather I knew was almost overweight (before cancer) and had several heart attacks in his lifetime.
It only gets harder and harder to avoid processed junk, and those "deals" where I'm not sure the meat is even meat anymore.
