Yes, it really does.

Think about it this way... Beans are renowned for their gaseous component. This is a sign that something isn't right in your digestion.
But if you soak your beans first adding a tablespoon or two of vinegar to it, they become much easier to digest.

Soaked porridge (as recommended in the WAPF's Nourishing Traditions book) becomes a wonderful tonic on the digestion. (1 cup oats, etc, 1 c water, 1 T live yogurt 1/4 c raisins - soak overnight on the counter. In the morning, add another cup of water and cook gently.)
