2. FAT SOLUBLE VITAMINS Vitamins A,D,E,K Sources Effects of deficiency

3. VITAMINS “VITAMIN” means “vital for life” VITAMINS are * Micronutrients which are necessary for everyday healthy functioning of the body

4. VITAMINS - Two main categories Water soluble B C Fat Soluble A D E K

5. Vitamin A Effects of deficiency Retarded growth, malformed bones Dry mucous membranes Xeropthalmia - dry eye membrane Night blindness Susceptibility to infection Sources Retinol - Cod liver oil, liver, dairy products, herring, egg yolk Beta-Carotene Dark green leafy vegetables, broccoli, carrots, deep orange fruits and vegetables

6. Vitamin D Effects of deficiency *Rickets in children and *osteomalacia in adults **Osteoporosis Dental caries * Conditions where bones are soft and cannot take weight of the body ** Bones become light, less dense and prone to fractures Sources Sunlight conversion Fish liver oils Dairy products Oily fish Margarine

7. Vitamin E Effects of deficiency Deficiency is rare Linked to conditions associated with malabsorption of fat Nerve damage, loss of balance, lowered immune system Anti coagulants and anti oxidants Sources Wheatgerm Oatmeal Oils and animal fats Leafy greens Eggs

8. Vitamin K Effects of deficiency Abnormal clotting, bleeding. Deficiency is rare Sometimes called “Coagulation” vitamin Sources Dark green vegetables Liver Lean meat Eggs Manufactured by bacteria in intestine

9. CONCLUSION The fat-soluble vitamins, A, D, E, and K, are stored in the body for long periods of time and generally pose a greater risk for toxicity than water-soluble vitamins when consumed in excess. Eating a normal, well-balanced diet will not lead to toxicity in otherwise healthy individuals. However, taking vitamin supplements that contain megadoses of vitamins A, D, E and K may lead to toxicity.
