Cooking doesn't destroy it. Vitamin B-12 doesn't break down—even at the boiling point of water—for several hours. A diet low in animal proteins, milk, or dairy foods may increase the need for vitamin B-12.

What are 3 major nutrients that are chemically broken down?

The food contains three macronutrients that require digestion before they can be absorbed: fats, carbohydrates, and proteins. Through the process of digestion, these macronutrients are broken down into molecules that can traverse the intestinal epithelium and enter the bloodstream for use in the body.

What are 3 factors that affect the nutrient content of a food?

Some of the most important factors are:
  • Genetics and gender.
  • Dietary energy concentration.
  • Environmental temperature.
  • Health status.
  • Stocking density.
  • Feeding strategy and degree of competition for feed.
  • Variability of nutrient content and availability in ingredients.

Does heat destroy vitamin C?

Vitamin C is a water-soluble and temperature-sensitive vitamin, so is easily degraded during cooking, and elevated temperatures and long cooking times have been found to cause particularly severe losses of vitamin C [12].

What foods block vitamin absorption?
