4. What do I need to know ? • Be able to apply the nutritional advice when analysing existing food products. Understand that diets with deficiencies or excesses of particular nutrients may lead to health related problems; • Investigate nutritional and dietary needs of different target groups: including vegetarians, diabetics, coeliacs, calorie controlled, those with nut allergies and lactose intolerance;

5. Learning Outcomes • KNOW • About potential deficiencies and excesses of certain nutrients • UNDERSTAND • How diet can affects health and relate to health related problems • BE ABLE TO • IDENTIFY at least FIVE different dietary needs . • DEFINE a deficiency disease – with examples • RESEARCH one special diet in detail – ICT • Using NUMERACY apply your understanding of proportion of the eatwell plate • APPLY knowledge of nutrition to past exam questions

6. Deficiencies or excesses of particular nutrients may lead to health related problems

7. Activity One : Deficiencies or excesses • What is a deficiency disease ? Give THREE examples • If we eat something to excess what does it mean ? What should we avoid the most and why ? Enjoy your food and eat in moderation - What does this actually mean ?

8. Activity Two : Moderation and the eatwell plate We are all being encouraged to eat in moderation 1. Select TWO recipes for a two course evening meal 2. Calculate the % of each food group 3. Evaluate the suitability of this meal – how well did it match the requirements of the eatwell plate

9. High Blood Pressure - Weight gain results in more fatty tissue. Fatty tissue requires oxygen and blood nutrients to survive. This causes an increase in the amount of blood circulating through the body. This results in greater pressure on the walls of the arteries, resulting in high blood pressure. Tooth Decay Tooth decay damages your teeth and leads to fillings or even extractions. Decay happens when sugar reacts with the bacteria in plaque. This forms the acids that attack the teeth and destroy the enamel. After this happens many times, the tooth enamel may break down forming a hole or ‘cavity’ into the dentine. The tooth can then decay more quickly. CancerBeing overweight heightens the risk for a number of cancers. These include uterine, breast, gallbladder, colon and prostate cancer. Complications of Unhealthy Eating Stroke The build-up of fatty acids in the arteries in the brain can contribute to blood clots that block blood flow to the brain, leading to stroke. Obesity occurs when there is excessive fat in the body which is caused when a person consumes more energy than they expend. Being obese is harmful to health and has an adverse effect on life expectancy. Obesity and being overweight is usually measured by the Body Mass Index (BMI) which takes into account a person's height, weight and gender. Diabetes Too much body fat leaves the body resistant to insulin. It is insulin that allows the body to maintain a healthy blood sugar level (glucose) and resistance to insulin leads to high blood sugar levels. Type 2 diabetes and obesity are an all to familiar combination.
