How many cherries can cause iron poisoning?

Generally, healthy adults may be at risk of iron poisoning if they consume more than 1,000 grams of cherries in a single sitting or exceed 2,000 grams per day; for special populations, the threshold is even lower. If in doubt, it is recommended to consult a healthcare professional in advance. Detailed analysis is as follows:

For healthy adults, although cherries contain higher iron levels compared to common fruits, the iron content per cherry is limited. Consuming 200–300 grams (approximately 20–30 cherries) in one sitting is within a safe range, allowing the body to normally metabolize the iron without causing toxicity. Iron poisoning symptoms such as nausea and abdominal pain typically occur only when excessive amounts are consumed in a short time, leading to iron intake far exceeding the daily recommended amount and resulting in iron accumulation in the body.

For children, elderly individuals, or those with abnormal iron metabolism conditions such as hemochromatosis, the body's ability to process iron is weaker. Even if their intake does not reach the risk threshold for healthy adults, iron may not be excreted efficiently, increasing the risk of poisoning and potentially causing more pronounced symptoms. These groups should strictly limit their consumption.

Cherry intake should be controlled according to individual health status, avoiding large quantities at once. If discomfort such as vomiting or dizziness occurs after eating cherries, consumption should be stopped immediately and medical attention sought to ensure safety.
