Elevated uric acid levels in the blood exceeding the threshold can lead to hyperuricemia and gout. If not well controlled, this condition can easily cause the formation of tophi granules, chronic gout arthritis, and joint deformities. Notably, excess uric acid can also deposit in the kidneys, impairing filtration function, leading to long-term kidney damage, even kidney failure.
Therefore, the treatment goal is to bring uric acid back to a safe level and maintain long-term stability. Besides medication, diet plays an important supporting role. Some foods that can help control uric acid, including diluted lemonade, are simple and easy-to-apply options if used correctly.
The reason lemon can help reduce uric acid is thanks to components such as citrate. This substance has the ability to alkalize urine. When the pH of urine is low (about 4.75), uric acid easily crystallizes and accumulates in the urinary tract. Conversely, when the pH increases to about 6.75, most uric acid exists in a soluble form, favorable for kidney excretion. Thanks to that, citrate helps reduce the risk of deposition and supports the process of uric acid elimination.
In addition, lemon is also rich in vitamin C - an important antioxidant. Vitamin C not only helps boost immunity, support collagen synthesis but also has the ability to promote uric acid excretion. The mechanism is believed to be related to increasing blood flow to the kidneys, improving glomerular filtration rate and reducing uric acid reuptake in the kidney tubes. At the same time, vitamin C also contributes to reducing oxidative stress, thereby indirectly supporting lowering blood uric acid levels.
In addition, flavonoid compounds in lemon - present in the skin, flesh and seeds - also bring many benefits. This group of substances has antioxidant, anti-inflammatory properties, supports blood vessel protection and improves some metabolic factors such as blood pressure and blood lipids. Improving these risk factors also indirectly contributes to supporting uric acid control and reducing inflammation in people with gout.
However, it should be noted that lemon juice only plays a supporting role. To effectively control uric acid, especially in people who have got gout or are at high risk, it is still necessary to follow medication as prescribed and maintain a reasonable lifestyle and diet.
