Being that guy again,
baking soda can kill you. Highlight:
But many experts do not consider sodium bicarbonate the treatment of choice for indigestion, even though it is effective and cheaper than most other antacids, said Dr. Stanley B. Benjamin, chief of the gastroenterology at Georgetown University Medical Center in Washington. "Physicians don't tell people to take baking soda for indigestion, even if it works, because of all the sodium it contains," he said. "Excess sodium causes things like high blood pressure, heart disease and kidney problems."
Dr. Benjamin said stomach ruptures were rare in cases that did not involve an ulcer or other abnormality. "The normal stomach is a tough, multi-partitioned organ that hardly ever ruptures," he said. "But like any other sac, like a balloon, it has a bursting point."
