Storing onions and potatoes together causes the potatoes to produce poisonous chemicals like solanine and chaconine, which can be fatal when consumed, especially for children.

Publisher’s rating: MISLEADING

The review says onions can accelerate potato sprouting and spoilage, but toxicity from solanine and chaconine is associated with consuming large quantities of green or sprouted potatoes. It concludes that claiming storage together alone creates deadly toxins exaggerates the food-safety risk.
