This uniquely American tendency to assign racism where none exists has struck again in yet another bizarre way. And it's absurd to try to make the case that we are racist toward Chinese food, when the number of Chinese restaurants triples those of U.S. cultural icons such as McDonald's and Starbucks.
Who hasn't heard of the so-called "Chinese Restaurant Syndrome" featuring symptoms such as headaches, flushing, sweating and heart palpitations tied to MSG consumption? Yet despite the supposed connection, controlled studies of the compound have not been able to establish a causal connection. So get out your chopsticks.
