Risky drinking games usually involve alcohol, but one teen learned not to swig soy sauce, either. A 19-year-old man in Virginia drank a quart of soy sauce on a dare. He first started twitching, and then had seizures and eventually landed in the hospital in a three-day coma. Doctors diagnosed him with hypernatremia, or dangerous levels of salt in the bloodstream. One quart of soy sauce can contain as much as a third of a pound (150 grams) of sodium. Excess sodium in the bloodstream pulls water out of nearby tissues by a process called osmosis, which equalizes the concentrations of salt across cells. Hypernatremia can extract so much water from the brain that it starts to shrink and bleed. www.livescience.com
