Although walnuts are a nutritious snack -- the University of Michigan Health System notes that they are a source of healthy fats -- candied walnuts are different, as they contain added sugar. However, you can still enjoy this snack if you assess the nutrition facts carefully.
The online nutrition resource MyFitnessPal explains that each 1/4 cup serving of candied walnuts contains 200 calories. The calorie expenditure information at MayoClinic.com notes that it would take just under an hour of weightlifting to burn off the calories in this serving of candied walnuts.
Candied walnuts are high in fat -- each 1/4 cup serving of candied walnuts contains 17g of fat. Of this fat, only 2g comes from saturated fat, while the rest comes from unsaturated fat.
Candied walnuts are higher in carbohydrates than regular walnuts because of the added sugars. Each 1/4 cup serving of candied walnuts contains 10g of carbohydrates, with 8g of sugar and 2g of fiber.
Candied walnuts are not a rich source of protein. Each 1/4 cup serving provides 3g of protein. MedlinePlus suggests consuming between 50 and 65g of protein daily to support health.
