What is hypovitaminosis?
Deficiency of vitamins
How does cooking affect the stability of vitamins?
Cooking can reduce the available quantity of vitamins due to exposure to oxygen, heat, or light.
Which type of vitamins are more affected by cooking methods?
Water-soluble vitamins are more affected by cooking methods compared to fat-soluble vitamins.
What happens to vitamins when exposed to oxygen?
The vitamins oxidise.
How does heat affect vitamin content in foods?
Reduce the effectiveness of vitamins or the amount that can be absorbed from a meal.
What is the effect of light on vitamin stability?
Storing vitamins in a dark place can help preserve them, as light can break down certain vitamins.
What are antioxidants?
Antioxidants are substances that combat oxidants formed through chemical reactions in cells, protecting important components like fats, proteins, and DNA.
