Regarding this, Can you eat potatoes that are sprouting when pregnant? Sprouted potatoes contain higher levels of glycoalkaloids, which can have toxic effects in humans when consumed in excess. Eating sprouted potatoes during pregnancy may also increase the risk of birth defects. They are safe up until the point that they start to go soft, even when sprouted.

Why are my fresh potatoes green?
Potatoes will often go green when they’re not stored properly and they’re exposed to light.

Is it OK to eat green potatoes if you peel them? Peeling of green potatoes will greatly reduce the levels of glycoalkaloids as they are localised just below the surface of the peel. However, if these potatoes taste bitter after peeling, then it’s best not to eat them.
