This link is review of the paleo diet from web md
It’s true cost can be barrier for paleo but also for any diet promoting high-quality foods. One suggestion is growing your own vegtables, fruits, herbs, and nuts – maybe raise some chickens if your county allows it (or frequently go noodling 🙂 ).
This is a good website to get started and learn about growing:
I built 4 raised garden beds and spent less than $20 to build each of them. Depending on the quality of soil you have you may need to bring some in. Try to find a bulk distributor, which is WAY cheaper than big box stores. They will deliver it – at least they do in Atlanta – and it definitely counts as a workout if you do it yourself 😉
Even starting small and growing only herbs will save you lots of money. Rosemary, for example, is a few $’s at the store. For that price you could have just about an endless supply of rosemary.
