I have had lots of problems with acididty and after research and a blood test discovered it was probably very much related to being gluten sensitive. I did not find that limes helped me a bit to be alkaline and even wheatgrass only helped somewhat. Baking soda has helped a lot... But I started having terrible cravings for milk products, even though I drank lots of milk. Guess what? Baking soda increases the need for calcium, it turns out. Whatever you use BS for, please be sure you get plenty of calcium!
