Tbf, that was not only smoke from cigarettes. Combustion engines and furnaces used to add a lot of smoke, too, before the use of catalysators and filters became compulsory.

Maybe the glycoalkaloid content differs between potatoe sorts? I have used sprouted potatoes my whole life without any issues whatsoever. Might have been just lucky that our potatoes are low on glycoalkakoids?

Ok – this is the official statement of the German Federal Agency for Risk Assessment.

TL;DR

• there have been only a couple of reports of glycoalkaloid poisoning through potatoe consumption during the last 100 years.
• sprouts, green parts and the skin of potatoes contain glycoalcaloids.
• cooking reduces glycoalcaloids.
• peeled and cooked potatoes are safe to eat.

Culinary preferences might make the difference: in Germany potatoes are eaten peeled = very low risk of poisoning, while my Canadian host family ate potatoes with their skin = slightly higher risk of poisoning, especially if you cut out sprouts but leave the skin.

It’s not a meme.
