Uric acid is a substance that's produced when your body breaks down purines. Purines are found in many foods, including organ meats, anchovies, herring, and mackerel. They're also found in yeast and beer. When uric acid levels become too high, it can lead to gout or kidney stones.
Lemon water can help flush out uric acid because of its high citric acid content. Citric acid helps to break down uric acid crystals and prevent them from forming again. Lemons are also a good source of vitamin C, which can help boost the immune system and fight infection.
