Deputy Director of Thai Hospital Warns: 5 Foods That Can Lead to Kidney Failure When Eaten in Excess

The Deputy Director of a major hospital in Thailand has issued a public warning about five commonly consumed foods that may significantly increase the risk of kidney damage and kidney failure when eaten regularly or in large amounts. As chronic kidney disease continues to rise globally, experts emphasize that dietary habits play a far more critical role than most people realize.

1. Processed Meats

Sausages, bacon, ham, and canned meats contain extremely high levels of sodium, preservatives, and phosphates. These compounds force the kidneys to work harder, accelerating kidney function decline. Long-term consumption is strongly linked to hypertension—one of the leading causes of kidney failure.

2. Instant Noodles and Packaged Foods

Ready-to-eat snacks, noodles, and frozen meals are packed with salt, flavor enhancers, and artificial additives. Excessive sodium intake causes fluid retention, raises blood pressure, and directly strains the kidneys.

3. Sweetened Beverages

Sodas, energy drinks, and bottled teas are loaded with fructose and refined sugar, which contribute to obesity, diabetes, and fatty liver—three key conditions that damage the kidneys over time. Studies show that people who drink sugary beverages daily have a significantly higher risk of chronic kidney disease.

4. Deep-Fried and Oily Foods

Repeatedly heated oils produce trans fats and oxidative toxins that trigger inflammation in the body. These harmful compounds circulate through the bloodstream and can gradually impair kidney filtration ability.

5. High-Protein Diets (Red Meat & Organ Meat)

Although protein is essential, consuming excessive amounts—especially from red meat or organ meats—results in a high metabolic load for the kidneys. Over time, this increases the risk of proteinuria and reduced kidney function.

Expert Recommendation

The Deputy Director stresses that kidney failure does not happen overnight. It is usually the result of:

• High-sodium diets

• High-sugar intake

• Dehydration

• Uncontrolled diabetes or hypertension

To protect kidney health, he recommends:

• Drinking enough water

• Reducing processed foods

• Eating more vegetables and whole grains

• Having annual kidney function tests after age 40
