Answer 2

Nutrient Content Is Often Altered During Cooking Cooking food improves digestion and increases absorption of many nutrients (1, 2). For example, protein in cooked eggs is 180% more digestible than in raw eggs (3). However, several key nutrients are reduced with some cooking methods. The following nutrients are often reduced during cooking: Water-soluble vitamins: Vitamin C and the B vitamins — thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), folic acid (B7) and cobalamin (B8). Fat-soluble vitamins: Vitamins A, D, E and K. Minerals: Primarily potassium, magnesium, sodium and calcium. Bottom Line: Although cooking improves digestion and the absorption of many nutrients, the levels of some vitamins and minerals may decrease.
