Better option: Read labels. Anything with more than 400 mg of sodium per serving should be avoided. Use natural herbs and spices to season your meals instead.

Poison 1: Sugar and Refined Flours

These are among the most damaging substances for your kidneys. They raise blood sugar, thicken the blood, and gradually injure nephrons. They are also major contributors to diabetes and high blood pressure, the two leading causes of kidney failure.

Immediate shift: Eliminate sugary drinks, reduce refined breads and cookies, and increase your intake of vegetables, legumes, and whole grains.

Warning Signs You Should Never Ignore

Although kidneys often fail silently, these symptoms deserve immediate attention:

• Foamy or bubbly urine
• Swelling in the feet or ankles
• Persistent fatigue
• Changes in the color or frequency of urination

Seek medical advice promptly if you experience any of these.
