Answer:

The kidneys play a vital role in removing waste and maintaining the body's balance of water, electrolytes, and blood pressure. They achieve this by filtering blood, reabsorbing essential substances, and excreting urine. Kidney function decline can lead to a buildup of toxins, severely impacting health. Several factors contribute to kidney function decline, primarily chronic diseases like diabetes, high blood pressure, and heart disease.

To maintain healthy kidneys, you need to drink enough water daily and consume healthy beverages. This supports the kidneys' filtering and detoxification functions, reducing the risk of kidney stones. Dehydration leads to concentrated urine, making it difficult to eliminate waste products, which increases the burden on the kidneys and can cause damage.

Many people drink soda, milk tea, and other sugary drinks instead of water. However, these drinks contain high levels of sugar, potentially causing various health issues. For adults without metabolic disorders or weight problems, the maximum daily intake of simple sugars should be around 10% of total daily calories. For individuals with diabetes or who are overweight or obese, this should not exceed 5%. A single can of soda (about 300 ml) often meets the entire daily recommended intake of simple sugars.

Consuming a large amount of soda, like 3-4 cans daily, over an extended period can contribute to health problems such as cardiovascular disease, high blood pressure, and diabetes. The high sugar content in soda increases blood sugar levels, potentially damaging the small blood vessels in the kidneys. This increases the burden on the kidneys, causing damage and reduced function over time. Sugar (especially fructose) can increase calcium and oxalate levels in the urine, promoting kidney stone formation.

Sugar increases the risk of insulin resistance and can lead to diabetes—a major risk factor for chronic kidney disease. Sodas also contain artificial sweeteners and other additives that can harm the kidneys with excessive or prolonged consumption.

Drinking multiple cans of soda daily increases the risk of chronic kidney disease. It is crucial to limit soda consumption, avoid drinking it at night, and refrain from using it as a water substitute. Drink at least two liters of water daily, or more during physical activity or when working outdoors, to stay hydrated and support kidney function. Supplement your water intake with lemon water or low-sugar fruit juices. Combine this with a healthy diet, sufficient sleep, and regular exercise to protect your kidneys.
