Natural glycoalkaloid toxins concentrate in the skins of potatoes.
Sweet potatoes are one of the healthiest known vegetables.
Any other natural toxins to consider? Well, potatoes produce these natural insecticide compounds called glycoalkaloids to keep potato beetles from nibbling on them—they’re not stupid. So bad for beetles, but what about us?
Well, a number of dietary risk assessments have been published lately, and although these glycoalkaloids are thought to be the most highly consumed natural toxin in North America, people have been growing potatoes for 7000 years, currently the 4th largest food crop in the world.
Major review just published, what do you think? Now this is for a baked potato, not fried, no butter, no cheese, no sour cream—no salt. Just a plain baked potato. Bad, neither, or good?
True safety, or false sense of security? Asking the question of “vital importance.” Are potato glycoalkaloids dangerous to humans? This discussion suggests they are indeed toxic and this problem should no longer be ignored. OK, then.
