Chemistry's hero of the acid reflux battle

If, like me, you suffer from GERD and the thought of a big, tasty meal always has to be balanced against the dread of acid reflux, you'll know what friend the compound sodium alginate can be. What's more, not only does it help with gastrointestinal nightmares, it also produces some Heston Blumenthal style delights by allowing chemi-chefs to go in for spherification. (Not to be confused with spaghettification, which is what happens to you if you get too near a black hole.)
