The bottom line is that no, you can't eat potatoes that have been undercooked. There are several reasons for this, most notably that raw potatoes contain a chemical compound called solanine. This is a very toxic compound to us humans, and it can even prove fatal if consumed in enough large amounts.
What happens if you eat undercooked potatoes?
Though attempting to digest raw starches isn't going to cause you any lasting bodily harm, the raw potato will pass through the digestive tract with very little breakdown, likely leading to an increase in unpleasant cramping, bloating, and gas production.
Is it OK to eat a potato that is a little raw?
Raw potatoes are more likely to cause digestive issues and may contain more antinutrients and harmful compounds. Yet, they're higher in vitamin C and resistant starch, which may provide powerful health benefits. In truth, both raw and cooked potatoes can be enjoyed in moderation as part of a healthy diet.
Are potatoes okay if they're a little bit soft?
A: Yes, it's OK to bake or boil slightly soft potatoes. I am assuming they don't have large sprouts (if you can knock off the sprouts with your finger or a brush that's fine too). Potatoes are 80% water on average, so some of that moisture drying up is natural.
