However, the time to eat onions also plays an important role in maximizing the effects on kidney health.
According to research, onions contain quercetin - a powerful flavonoid with anti-inflammatory effects, helping to reduce renal tube damage in chronic diseases. Quercetin is most effective when absorbed into the body when hungry or when insulin levels in the blood are low.
Therefore, according to recommendations, eating raw onions in the morning before meals or at breakfast is the ideal time to absorb bioactive substances that are good for the kidneys.
Onions are a low- potassium food, very suitable for people with kidney failure or on dialysis - subjects who need to limit potassium in their diet. Cooked onions, especially when stewed or lightly stir-fried at lunch or dinner, help the body digest easily and limit the accumulation of toxins in people with impaired kidney function.
Eating onions in the evening can help improve sleep quality by stabilizing blood sugar and reducing oxidative stress - thereby indirectly supporting the kidney's blood filtration function at night, when the kidneys are active.
Onions should be eaten in the morning to optimize the absorption of antioxidants, or at lunch and dinner in the form of cooked to support digestion and maintain long-term kidney function. The right time to eat, combined with a healthy diet, can play an important role in protecting and improving kidney health.
