Does a Potato Lose its Nutritional Value When Cooked?

Q:

Does a potato lose its nutritional value or fiber content when baked, fried or microwaved?

 

A:

According to USDA data, microwaving potatoes is the best way to retain its nutritional value, boiling potatoes causes the most nutrient loss, and frying adds fat and extra calories. None of the cooking methods destroy fiber. Still, potatoes are rich in key nutrients regardless of how they are cooked.
