Values for sweet potato vary by brand and how it is cooked. Check the pack. General information, not medical advice.
Baked looks a little higher
Baking drives off some water, so each 100 g of baked sweet potato holds a little more than raw. Weigh the sweet potato the same way each time and use the matching row.
Against a regular potato
The comparison table sets baked sweet potato beside baked white potato and other starchy foods. They are close in calories. Sweet potato has more fibre and more sugar.
Toppings are separate lines
Butter, sour cream, cheese and chips each add their own. A plain baked sweet potato is a modest number; a loaded one is a different meal.
