1. People with Kidney Problems
Sweet potatoes are naturally high in potassium, a mineral that plays a vital role in regulating blood pressure, nerve function, and muscle contractions. While potassium is usually good for you, people with chronic kidney disease or impaired kidney function need to be careful.
Healthy kidneys filter excess potassium out of the blood, but when the kidneys don’t work properly, potassium can build up to dangerous levels. This condition, called hyperkalemia, can lead to irregular heartbeats and serious complications. For that reason, those with kidney disease should consult their doctor before adding sweet potatoes to their diet.
2. People Prone to Kidney Stones
If you’ve ever had a kidney stone, you know how painful it can be. Sweet potatoes contain oxalates, natural compounds that can combine with calcium to form calcium oxalate stones. For individuals with a history of kidney stones, eating foods high in oxalates may increase the risk of recurrence.
That doesn’t mean you must avoid sweet potatoes altogether, but it does mean practicing moderation and pairing them with calcium-rich foods (like yogurt or cheese), which can help reduce oxalate absorption in the gut.
3. Individuals with Blood Sugar Concerns
Sweet potatoes have a lower glycemic index than white potatoes, meaning they cause a slower, steadier rise in blood sugar. Still, they are a source of carbohydrates and natural sugars. People with type 2 diabetes or insulin resistance should watch portion sizes closely.
