What are the harms of eating pickled onion bulbs long-term?

Generally, long-term consumption of pickled onion bulbs (Qiaotou) may lead to elevated blood glucose levels, impaired circulation, adverse effects on the kidneys, liver cirrhosis, and nervous system disturbances. The specific details are as follows:

1. Elevated Blood Glucose Levels

Qiaotou contains relatively high levels of protein and carbohydrates. Excessive intake can easily cause blood sugar fluctuations. For diabetic patients, prolonged consumption may raise blood glucose levels, potentially leading to complications and seriously threatening health.

2. Impaired Circulation

Due to its high content of cholesterol, unsaturated fatty acids, and saturated fatty acids, long-term consumption of Qiaotou can negatively affect blood circulation, promoting hardening of the blood vessels. In severe cases, this may result in insufficient cerebral blood supply and trigger complications such as stroke.

3. Adverse Effects on the Kidneys

Qiaotou is rich in phosphorus. Prolonged consumption increases blood phosphorus levels, which can strain the kidneys, cause kidney discomfort, and ultimately lead to renal failure.

4. Liver Cirrhosis

Substances in Qiaotou such as cholesterol and unsaturated fatty acids can increase the liver's metabolic burden when consumed over a long period. This may damage liver cells, cause symptoms of liver discomfort, and eventually lead to liver cirrhosis.

5. Nervous System Disturbances

Qiaotou contains elements such as phosphorus and iron. Long-term consumption increases their levels in the blood, potentially affecting the nervous system and worsening neurological control dysfunction, possibly resulting in symptoms such as insomnia and anxiety.

In summary, while Qiaotou is a nutritious food, prolonged or excessive consumption may lead to various adverse effects. It is advisable not to consume it excessively over long periods to avoid health risks. If any discomfort occurs, prompt medical attention is recommended.
