I don't know if cacao has sulphur or what component in it detoxifies mercury, but either way it's not a realistic main source of any detox program. You need to consume a lot of something to make a difference in a detox program. Have you priced raw cacao? EXPENSIVE. There are much much much much much cheaper and easier sources of sulphur.

I have a huge tub of MSM (sulphur) - it's pretty inexpensive stuff and very easy to mix into drinks.

Eggs, cabbage, onions, shallots, brussels sprouts, etc... are great sources of sulphur. Cooking reduces the sulphur content, so raw is best.

And Goji berries? Geez I hope you have a trust fund or something.

Don't get caught up on the idea that it takes lots of money to detox! The cheapest stuff is often the best.
