Which individuals need to carefully monitor potassium intake due to the risk of hyperkalemia from consuming large daily portions of cantaloupe or watermelon?

Individuals with advanced chronic kidney disease (CKD)

While the potassium content in melons is generally beneficial for maintaining healthy blood pressure regulation in most of the population by balancing sodium levels, this essential mineral poses a risk to specific patient populations. Individuals diagnosed with advanced chronic kidney disease (CKD) often have compromised renal function, meaning their kidneys struggle significantly to effectively excrete excess potassium from the body. If a person with this condition consumes large daily amounts of high-potassium fruits like cantaloupe or watermelon, the inability to eliminate the surplus can lead to a dangerous buildup known as hyperkalemia. Therefore, consultation with a renal dietitian is explicitly recommended for these patients before incorporating large, daily servings.
