The kidney is the organ that filters blood and maintains water balance - electrolytes in the body. Without a suitable diet on hot days, the risk of kidney stones, acute renal failure or urinary tract infections can increase.
First, drinking enough water is the most important thing. According to the World Health Organization, an adult should drink an average of 2 to 2.5 liters of water per day and need to drink more if exercising or outdoors. You should drink water, coconut water, diluted lemon water; Avoid drinks containing sugar, caffeine or alcohol because they cause diuretic, dehydration and increase pressure on the kidneys.
Second, reduce salt in your portion sizes. Eating salty foods causes the body to retain water, increase blood pressure and make the kidneys filter more sodium. Experts recommend not to consume more than 2.3g of sodium/day (equivalent to 1 teaspoon of salt).
Third, limit foods high in animal protein and oxalate such as red meat, organs, bone broth, spinach, chocolate... because they increase the filter load of the kidneys and the risk of stones. You should increase vegetables with high water content such as watermelon, squash, squash, cucumber.
Another note is to eat small meals, avoid eating well in hot weather because it can increase metabolism and dehydration. Processing methods such as boiling, steaming, and cooking cool soup are better than frying.
To protect your kidneys in hot weather, you need to stay hydrated, limit salt and protein; increase cool, healthy foods. A reasonable diet not only helps keep the kidneys healthy but also keeps the body balanced in harsh weather.
