Find out how much energy there is in different foods
You should start this project by selecting lots of different foods to test. Suitable foods include: peanuts, cornflakes, rice, carrot, potato, apple, raisin, bread, pasta, crisps (ask your teacher if you want to use something else). Pick about five different types of food. You’re going to start by carrying out four food tests. These will tell you if the food has any of the following: protein, fat, reducing sugar (such as glucose) and starch.
Investigate the fat and salt content of different ‘spreads’
You should start this project with some research. You should find out about the various different types of spread that are available. For example, butter, margarine and their numerous alternatives (low-fat, no-added salt etc.) Ask people which they buy, and ask for their reasons. Find out what saturated and unsaturated fat means. You could visit the Food Standards Agency website (www.foodstandards.gov.uk ) to find out just how low in fat something has to be before it can claim to be low-fat on its label. At the end of this investigation you should suggest which type of spread should be used by a coronary heart disease patient. Therefore, before you start any tests, you should research the disease. Find out about the affects of high cholesterol and high blood pressure, and what in turn can cause these symptoms.
Investigate nutritional needs for nutritional disorders
This project is split into two main sections. The first is very much research-based. The second involves analytical chemistry and biology, as you will conduct food tests. Your aim is to collate data and information and suggest two menus for two days for somebody with a nutritional disorder.
