1.9 Key points about vitamins

  1. Vitamins A, D, E and K are fat-soluble; the remainder are water-soluble.

  2. Adequate amounts of vitamins are required, many on a regular basis, though some can be stored.

  3. A balanced diet should provide the necessary amounts of vitamins, but people on a restricted diet need to take particular care to ensure an adequate intake of all of them.

  4. Deficiency diseases can occur when vitamins are absent or in short supply.

  5. Water-soluble vitamins are easily lost during cooking, and are destroyed by exposure to air and light, so care is needed in food preparation to preserve them.
