Task 1a
Produce a booklet suitable for patients in a health centre to improve their understanding of nutrition. Start with a page explaining the terms: food, diet, meals and nutrients. Explain what nutritional measures dietary guidelines could be used to identify a person who was malnourished, undernourished, and deficient in certain nutrients, overweight or obese. Use charts and tables with annotation or brief summaries, for you to demonstrate your understanding of the information presented. Simple calculations of BMI from given data (or your personal data) will demonstrate understanding. Use illustrations and examples to make the information easier to understand. Explain the dietary intake guidelines that are published to help individuals to have a balanced diet.

Task 1b
Carry out researching to extend your knowledge about one of the nutritional issues (food labelling, organic good, genetically modified foods, environmental aspects of food product, self-prescribed health supplements or treatments for obesity and advertising food). Then prepare a wall display or presentation to explain how that issue impacts on the nutritional content of food (P1).

Concepts of Food

Food is any ingredient eaten to feed the body. Food can be solid or liquid, and can be taken by mouth, by tube or even directly into a vein, if an individual is incapable to eat or drink generally.

A diet states to the types of food eaten frequently by an individual. The word diet does not essentially bring up to a weight loss diet. A person’s diet means all the meals and snacks they eat.

Meals and Snacks
The outdated pattern of eating three meals a day still exists in some homes, but an important number of people increase a lot of their food intake from snacks. Some people have snacks in the middle of meals if they feel hungry, and occasionally just because the food is there and they eat it out of boredom. Snacks are not necessarily unhealthy.

Nutrients are the exact chemical elements of food that offer energy or support growth, repair or usual operative of the body. Protein, carbohydrates, vitamins and minerals are all nutrients.

1.2 Nutritional Health
Malnutrition simply means that a body does not take in enough food or drink (nutrition) to enable it to function correctly and healthily. Many very skinny people are malnourished, not just those kids you see on the news in areas hit by famine. Malnutrition can mean lack of vitamins, lack of protein or simply lack of calories. Severe malnutrition shows various symptoms including a distended stomach; also it can cause unseen symptoms such as bone disorders,

Overweight refers to increased body weight in relation to height, when compared to some standard of acceptable or desirable weight.
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health. It is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders, medications or psychiatric illness scientifically, a person is considered obese when his/her body mass index (BMI) exceeds 30 kg/m2. A person’s BMI is obtained by dividing a person's weight by the square of the person's height.

1.3 Nutritional Measures
Nutritional and Energy Balance
Energy balance also has to do with what’s going on in your cells. When you’re in a positive energy balance (more in than out) and when you’re in a negative energy balance (more out than in), everything from your metabolism, to your hormonal balance, to your mood is impacted.
