Can you still eat a potato after removing the sprouts if it has sprouted?

Introduction
Can you still eat a potato after removing the sprouts? It is not recommended to eat potatoes that have sprouted, even if the sprouts are removed. Potatoes naturally contain small amounts of solanine, which is generally harmless to humans. However, during prolonged storage, the solanine content can gradually increase, potentially leading to poisoning. If solanine reaches a certain level, it may cause paralysis of the respiratory muscles and symptoms such as throat itching.

In general, whether sprouted potatoes can still be eaten after removing the sprouts depends on the condition of the potato. If any discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:

1. Edible

If the potato has only just begun to sprout, with small and few sprout eyes, it may be safe to carefully cut out the sprout eyes and the surrounding tissue. When potatoes sprout, they produce solanine, a toxin that is primarily concentrated in and around the sprout eyes. As long as the cutting is deep enough to remove all potentially affected areas containing solanine, the remaining potato can still be consumed. If, apart from the sprouted parts, the rest of the potato shows no signs of greening, softness, or decay, maintains a firm texture, and has no unusual odor, it can be safely eaten after proper removal of the sprouted portions.

2. Not edible

If the potato's surface has turned significantly green or has multiple large sprout eyes, this indicates a high accumulation of solanine. Even after removing the sprouts, the remaining portions may still contain harmful levels of toxins and should not be consumed. Additionally, if the potato exhibits soft spots, mold, or an unpleasant smell along with sprouting, it means the potato has started to rot and may be contaminated with bacteria or fungi. Eating such potatoes could lead to food poisoning, so they should be discarded immediately and not eaten.

To avoid unnecessary harm to the body, it is advisable to consult a healthcare professional before deciding whether to consume sprouted potatoes. To ensure food safety, store potatoes in a cool, dry place after purchase, inspect them regularly, and use or dispose of them promptly to prevent sprouting or spoilage due to prolonged storage.

What should not be consumed with sago?
Sago is generally not recommended to be consumed with high-starch foods, cold-natured fruits, greasy foods, gas-producing foods, or foods high in tannins. Sago itself is extremely high in starch; when consumed together with high-starch foods such as potatoes, sweet potatoes, and corn, it may lead to excessive starch intake. These foods are digested slowly in the intestines and are prone to accumulate and ferment, potentially causing digestive discomfort such as bloating and constipation.
