Many scientific studies and prestigious health organizations in the world have shown a positive link between the consumption of vitamin C from natural foods and kidney function.
According to research, vitamin C is a powerful antioxidant that helps neutralize free radicals - a factor that damages kidney cells, especially in people with diabetes or high blood pressure. If these free radicals accumulate for a long time, they can impair the filtering function of the kidneys and increase the risk of chronic kidney disease.
Foods rich in vitamin C such as oranges, tangerines, kiwis, strawberries, broccoli, red bell peppers... have been recommended by the World Health Organization to be used regularly in the daily diet to protect the body from chronic diseases, including kidney disease. The World Health Organization affirms that vitamin C has the ability to improve blood circulation to the kidneys, supporting the process of filtering and excreting waste more effectively.
A study published in the Journal of Renal Nutrition also showed that people with high levels of vitamin C consumption from food have a 20% lower risk of chronic kidney disease than the low-consumption group. Vitamin C also helps limit the formation of calcium oxalate kidney stones by combining them with compounds in urine to prevent crystallization.
Not all forms of vitamin C are good for the kidneys
However, it is important to note the amount of vitamin C supplemented. According to household stories, high doses of vitamin C supplements (over 2,000mg/day) can be harmful to the kidneys, especially for people with a history of kidney stones. Therefore, prioritizing vitamin C from natural foods is a safe and effective choice.
To maintain healthy kidneys, eating foods rich in vitamin C is a scientific, natural and easy-to-do solution.
