10. Function Signs of Deficiency Osteomalacia (in adults) and rickets (in children) Curved spine, bow-legs, deformed pelvis Muscular and bone pain CALCIUM Essential for calcium absorption to build strong bones and teeth

11. Fat soluble Vitamin E (tocopherol)Sources; richest in vegetable and seed oils and whole grain cereals

12. Function Signs of Deficiency Deficiency is rare except where the immune system is compromised from factors such as pollution, smoking and coeliac or liver disease. May be more at risk of cancer and CHD due to permeability of the cell membranes. Antioxidant which promotes healthy cell membranes. Associated with prevention of cancer and coronary heart disease.

13. Fat soluble Vitamin K (napthoquinone) Sources; richest in green leafy vegetables. Also found in tea and products containing vegetable oils and margarine

14. Signs of Deficiency Function- essential for clotting the blood • Deficiency is rare except in the new born as levels of this vitamin are low in human milk. • Infants are routinely given this vitamin either by mouth or injection as a prevention of deficiency. • Newborns who are deficient can suffer spontaneous bleeding, which can lead to brain haemorrhage and death.

15. IronHaem (animal) iron sources; red meat, liver and kidneyNon haem (plant) iron sources; green leafy vegetables, lentils and fortified breakfast cereals

16. Function Signs of Deficiency • Iron deficiency anaemia; • lack of energy • shortness of breath • heart palpitations • pale complexion To make haemoglobin in red blood cells which carry oxygen in the blood

17. Sources Mineral: Calcium Milk, cheese, yoghurt, green leafy vegetables and fish with edible bones such as salmon and sardines

18. Signs of Deficiency Function Osteomalacia (in adults) and rickets (in children) Curved spine, bow-legs, deformed pelvis Muscular and bone pain • Formation and development of • bones and teeth • Contraction of muscles including • the heart • Nerve function • Blood clotting

19. Potassium Found in most types of food. Good sources of potassium include: fruit, vegetables, nuts, Seeds, pulses, milk, Fish, shellfish, beef, Chicken and turkey

20. Function Signs of Deficiency • used to control pH and osmotic pressure within the cells and therefore maintain blood pressure • electrolyte (fluid) balance • nerve function Hypokalaemia; muscle weakness, tingling or numbness, fainting due to low blood pressure

21. Zinc Good sources are meat, seafood and dairy products

22. Sodium Many concentrated sources of sodium are obvious because of their salty taste.

23. Signs of Deficiency Function FLUID BALANCE! • Muscle cramps • Fluid retention • Headache • Nausea and vomiting Regulating body water content and electrolyte balance

24. Iodine A trace element found in seawater, rocks and some types of soil. Can be found in some plant foods depending on the soil in which the plants are grown. However, the richest sources are seawater fish, seaweed and shellfish.

25. Signs of Deficiency Function Stimulates the thyroid gland to make hormones which are involved in controlling metabolism. Goitre- swelling of the thyroid gland, seen in developing countries Lethargy and weight gain

26. PhosphorusGood Sources

27. Phosphorus Signs of deficiency Function There is no danger of the body becoming depleted of phosphorus unless under a starvation diet when the muscle, brain and nervous system can be severely affected • maintenance of normal bones and teeth • the production of energy • normal function of cell membranes

28. Estimated Average Requirement (EAR) No. of people EAR Requirements

29. Estimated Average Requirement (EAR) This is an estimate of the average requirement for energy or a nutrient. The EARs for energy are based on the present lifestyles and activity levels of the UK population. Approximately 50% of a group of people will require less energy or nutrient, and 50% will require more. No. of people EAR Requirements

30. Reference Nutrient Intake (RNI): No. of people RNI Requirements

31. Reference Nutrient Intake (RNI): RNI is often used as a reference amount for population groups to indicate the amount of a nutrient that is enough to ensure that the needs of nearly all the group (97.5%) are being met. The RNI is used for recommendations on protein, vitamins and minerals. No. of people RNI Requirements

32. Lower Reference Nutrient Intake (LRNI) No. of people LRNI Requirements

33. Lower Reference Nutrient Intake (LRNI) LRNI is a useful measure of nutritional inadequacy . It indicates the amount of a nutrient that is enough for only the small number of people who have low requirements (2.5%). The majority of people need more. No. of people LRNI Requirements

34. Guideline Daily Amounts (GDAs)

35. Guideline Daily Amounts (GDAs) These are guidelines for healthy adults and children about the approximate amounts of calories or nutrients required for a healthy Diet. Often used by food retailers to display the amount of energy (in kilocalories or kilojoules) and/or fat, saturated fats, sugars and salt in food and drink products in relation to DRVs. It is not compulsory to display this information.

36. Dietary Reference Values (DRV)

37. Dietary reference values (DRV) An umbrella term given to the estimated dietary requirements of particular groups in a population. There are three types of DRVs; EAR, RNI and LRNI. DRVs are important for ensuring adequate intakes of energy and nutrients throughout life and assist in preventing malnutrition. DRVs are estimates of the requirements for groups of people and are not recommendations or goals for individual people.
