POTATOES:Here are some tips that will help you in reducing the loss of potato nutrients:
a. Avoid peeling the potatoes before cooking them. The outer shell provides a good protection against nutritional loss during the cooking process. The protein and mineral content beneath the skin is very high and if you cook the potatoes after peeling them, most of these proteins and minerals are lost.
b. When you boil potatoes, first heat the water to its boiling point and then add potatoes. This will reduce the cooking time and help you maintain Vitamin C content.
c. Minimize frying as 75% of Vitamin C is lost during frying. You can use other cooking methods such as baking and steaming. On a different note, have you ever tried barbecue roasted potatoes?
