Can cooked unripe green apples make you sick?

Unripe green apples contain a higher concentration of certain compounds, such as tannins and malic acid, compared to ripe apples. These compounds can cause irritation and discomfort to the digestive system, leading to symptoms like nausea, vomiting, stomach pain, and diarrhea. Additionally, unripe apples are hard to digest and may cause intestinal blockage in severe cases.

Therefore, it's generally advisable to avoid consuming large quantities of uncooked, unripe green apples, especially if you have a sensitive digestive system. If you do choose to eat them, it's best to consume them in moderation and ensure they are thoroughly cooked to reduce the potential for adverse effects.
