This group should eat only very small amounts and choose well-cooked, soft sweet potatoes.
2. People with diabetes (if eaten incorrectly)
Sweet potatoes have a moderate to high glycemic index, especially:
- Baked sweet potatoes
- Soft, sugary sweet potatoes
- Fried sweet potatoes
→ These can easily cause post-meal blood sugar spikes.
People with diabetes should only eat:
- Boiled sweet potatoes
- Portions of 50–80 g per serving
- Combined with vegetables and protein to slow sugar absorption
3. People with kidney disease – potassium restriction
Sweet potatoes are very high in potassium. For people with kidney failure, chronic kidney disease, or those on dialysis, eating too much can lead to:
- High blood potassium levels
- Heart rhythm disturbances
- Muscle weakness and tingling
This group should consult a nutritionist or doctor before eating sweet potatoes.
4. People with active stomach or duodenal ulcers
Sweet potatoes can stimulate gastric acid secretion, which may worsen symptoms during flare-ups:
- Burning discomfort
- Acid reflux
- Upper abdominal pain
Only eat them once symptoms have settled, and choose soft, low-fiber preparations.
