One of them is pickled onions. According to the World Health Organization (WHO) and studies from the American Heart Association and other nutrition organizations, pickled onions can be harmful to health if not used properly.
People with high blood pressure
According to the World Health Organization, one of the main risk factors for high blood pressure is a high salt diet. Pickled onions contain high amounts of sodium due to the salting process, which can increase blood pressure in people with a history or existing high blood pressure. Studies have shown that consuming too much salt can increase the pressure on blood vessel walls, causing serious cardiovascular problems. It is recommended to limit sodium intake in the diet to control blood pressure and prevent cardiovascular complications.
People with kidney disease
People with chronic kidney disease should also avoid eating pickled onions. A high-salt diet puts a strain on the kidneys, making it harder for them to filter and remove waste from the body. This can cause kidney disease to progress more quickly. Pickled onions, with their high sodium content, can increase kidney pressure and worsen the condition.
People with stomach and digestive problems
Pickled onions are mildly acidic and can irritate the stomach lining, increasing the risk of stomach ulcers or gastritis if eaten in excess. People with a history of stomach problems such as peptic ulcers, or irritable bowel syndrome, should avoid consuming salty foods such as pickled onions.
People with gout
The sodium in pickled onions can increase uric acid levels in the blood, a major factor in gout. A salty diet can increase the risk of gout flare-ups, causing arthritis and serious joint damage.
