An interesting fact: The amino acids in your own cells react with sugars over time, in a very slow version of the Maillard reaction, to render proteins in your tissues dysfunctional, which, scientists say, is a component of human ageing! Imagine the irony in the fact that the same reaction that makes your onions delicious is also the reaction that slowly kills you. This is also why doctors keep telling you to keep your blood sugar levels low.
