Transcript: Is Bacon Good or Is Spinach Bad?
Nitrites: Harmful, harmless, or helpful?
Nitrites are preservatives added to cured meats—like bacon, ham and hot dogs—to prevent botulism and make them pink by combining with iron in the blood in the meat.
Everybody knows nitrites are bad for you, right?
But wait a second, didn’t I just show all this research suggesting that in fact the reason dark green leafy vegetables may be so healthy is that the nitrates in them turn into nitrites in our mouths? And the nitrites go on to produce nitric oxide which is what's so great for our arteries. So which is it? Are nitrites good for you or bad for you?
If nitrites are good for you, then hey—pass the bacon. If nitrites, however, are bad for you, then shouldn't we stay the heck away from spinach?
On one hand, we have the food group widely considered to be worst possible thing you can eat, processed meat, and on the other hand you have dark green leafy vegetables, considered the best. Yet they are respectively being trashed and touted for the exact same reason—nitrites. It’s got to be one or the other, right?
Now things are starting to get interesting… —stay tuned.
