Filtered water
Filtered water is always the most important drink for kidney health. When the body is supplied with enough water, the kidneys will work more effectively in filtering blood, removing waste and eliminating it through urine.
Maintaining a habit of drinking enough water also helps reduce the concentration of minerals in urine, thereby limiting the risk of kidney stones. The amount of water needed each day can vary depending on age, physical condition, exercise level and weather conditions. In summer, water demand usually increases because the body loses a lot of fluid through sweat.
Watermelon juice
With more than 90% water content, watermelon is an ideal fruit to replenish fluids for the body in the summer. In addition to its hydration ability, watermelon also contains lycopene and many antioxidant compounds that help reduce inflammation and protect cells from damage.
This fruit also has a mild diuretic effect, contributing to increasing urine output and supporting the body to eliminate excess salt. To avoid consuming too much sugar, you should prioritize eating fresh watermelon or using pure juice without added sugar.
Green tea
Green tea contains a large amount of polyphenols, especially EGCG (epigallocatechin gallate), a powerful antioxidant capable of reducing inflammation and limiting oxidative stress - factors that can negatively affect kidney function.
In addition, green tea also contributes to replenishing water for the body, supporting the process of eliminating waste and maintaining electrolyte balance. However, because it still contains caffeine, each person should only use it at a moderate level, avoiding drinking too much or using it in the evening if you are prone to insomnia.
Lemonade
Lemon juice is a familiar cooling option in the summer, and also brings many benefits to the kidneys. This drink provides citric acid, a compound that can prevent the combination of calcium with other minerals in the urine, thereby reducing the risk of stone formation.
You can add a few slices of fresh lemon to your drink or mix diluted lemon juice to increase your body's natural citrate intake. However, you should limit sugar intake to avoid reducing health benefits.
Coconut water
Coconut water is a natural source of liquids and electrolytes such as potassium, magnesium and sodium, helping the body maintain water balance on hot days. Some studies show that this drink can help prevent kidney stones thanks to containing citrate, a substance that helps limit the convergence of mineral crystals in the urinary tract.
However, due to the quite high potassium content, people with chronic kidney disease or those who are having to control potassium in their diet need to consult a doctor before using it regularly.
