Do High Temperatures Destroy Vitamin C Benefits?
The content of vitamin C in raw potatoes in the USDA National Nutrient Database is 11.4 milligrams per 100 grams, and the value decreases to 7.6 milligrams in canned potatoes. Humans do not consume fresh potatoes and the vitamin is known to be susceptible to degradation by food preparations used in home and commercial food processing. Boiling in water can quickly decrease vitamin C content in potatoes by 10% in 10 minutes. However, baking and microwaving can retain more than half of vitamin C because vitamin C does not leach out from potatoes into water and then degrade. Thus, vitamin C content in cooked potatoes can be varied depending on style of preparations.

Are There Carcinogens in Roasted Nuts?
Concerns about carcinogens in roasted nuts centers on acrylamide, a compound formed when certain plant foods are cooked at temperatures above 250 degrees, especially by frying, baking, broiling or roasting for long cooking times. Cooking causes a chemical reaction between sugars in the food and an amino acid called asparagine, which in turn forms acrylamide. Among the foods most noted for producing acrylamide are potatoes, leading to concerns about French fries and potato chips.
