How much for milk chocolate? That’s my Jones.
It’s hard to say, since there are so many versions. I picked dark chocolate because it has the highest concentrations of the flavanoids.
But, in general, it would be like 10-12lbs.
There are really only two ways to do this: (1) supplementation or (2) using cocoa as a consistent ingredient in your food, like with chili, mole, coffee, stews, etc.
Cocoa nibs (roasted beans) in some sort of trail mix would work, too.
