If the Sprouts Are Small
If the potato is still firm and only has a few small sprouts, you may be able to save it.
Remove:
The sprouts
The “eyes”
Any green areas on the skin
Then peel the potato thoroughly before cooking.
If the Potato Is Wrinkled or Heavily Sprouted
If the potato has:
Multiple large sprouts
Wrinkled skin
A shriveled appearance
Soft spots
it’s best to throw it away.
At this stage, the potato has begun breaking down and may contain higher concentrations of naturally occurring toxins.
When in doubt, it’s safer to discard it.
The Hidden Toxins in Sprouted Potatoes
All potatoes naturally contain compounds called:
Solanine
Chaconine
These substances help protect the potato from insects and disease.
In fresh potatoes, the levels are generally low and not a concern.
However, as potatoes age, sprout, or become exposed to light, these compounds can increase.
The highest concentrations are typically found in:
Sprouts
Eyes
Green portions of the skin
The white flesh of the potato contains much lower levels.
Consuming large amounts of these toxins may lead to symptoms such as:
Nausea
Vomiting
Diarrhea
Stomach pain
Headache
Fever
Most cases are mild, but some individuals may experience more severe reactions.
Does Cooking Destroy the Toxins?
Unfortunately, cooking alone does not completely eliminate solanine and chaconine.
Boiling, baking, frying, or roasting may reduce some toxins, but significant amounts can remain if sprouts and green areas are not removed first.
That’s why proper trimming and peeling are important whenever you choose to use a lightly sprouted potato.
And raw sprouted potatoes should never be eaten.
What About Green Potatoes?
Have you ever noticed a potato turning green?
The green color itself comes from chlorophyll, the pigment plants use during photosynthesis.
Chlorophyll isn’t harmful.
