I think this is a perfect example of why there is so much bad "logic" in nutrition science. Everything in this article may be true (potatoes with sprouts have a higher concentration glycoalkaloids), but there is 0 evidence that is something any human actually needs to worry about, especially given the other comments in this thread.
It's similar to the bad advice that was prevalent in the US for decades that eggs are bad for you. Thinking was just basically "People with high cholesterol are at greater risk of coronary disease, and egg yolks have a lot of cholesterol, thus, egg yolks bad." When they did actual studies, they found this to be nonsense for the vast majority of people because eating more eggs did not raise their serum cholesterol levels.
