Which vitamin is lost when heated?
Vitamin C is a water-soluble vitamin that helps in growth and development and is also called ascorbic acid. It is a temperature-sensitive vitamin that gets destroyed at elevated temperatures.
Does magnesium get destroyed by cooking?
Magnesium is a mineral and unlike vitamins, nothing can be created or destroyed in the process of cooking. That being said, magnesium can be lost in the cooking water during boiling and steaming, especially the longer the process takes place.
Is vitamin D destroyed by cooking?
Cooking may cause detrimental loss of vitamin D, but it depends on the actual foodstuffs and the heating process. Further research is needed to optimise cooking procedures to enhance retention of vitamin D. Vitamin D retention should be taken into account in future calculations of dietary intake of vitamin D.
