Salt
For some years now, salt has been viewed as a major cause of high blood pressure. But the reality is a little more complex. For people with a genetic pre-disposition, salt may be a killer; for others it may not be such a problem. But until a satisfactory test is developed, it’s wise for all of us to greatly reduce the amount of salt we consume.

Sugar
The more sugar we eat, the less complex carbohydrate and the more fat we eat. For that reason, sugar, with its empty kilojoules, is a food we should eat less of. But there’s also the problem of dental caries: despite all the improvements in tooth-paste and fluoridation over large areas of Australasia, sugar which is hidden in an amazing variety of foods, is still public enemy number 1.

Grrls in IT
Information Technology is the world’s fastest growing industry, responsible for decisions and innovations that affect our daily lives as much as government policy – but not enough women are interested in IT as a career. This program aims to dispel a range of preconceptions many young women have about joining the industry: Working in front of a screen all day, too “geekie”, technical and dull, needing a high level math and science background, and not enough variety and social interaction.

Food Packaging and The Environment
As most people don’t have a farm or food processing plant in their back yard, there needs to be a way to get food from its point of production to the people who eat it. In many cases disposable food packaging is a key component that helps this happen. While this disposable packaging performs many useful functions, such as containing, protecting, and preserving food, it also has a downside in its impacts on the environment.

Food Testing: Working with Yeast
Food testing is a key part of most food technology courses. In this concise program, with the aid of teachers and students at one of Melbourne’s leading high schools, we look at yeast its biology, its history, and the necessary conditions for its growth. Varying contents are used in six test tubes to show why only one of them will inflate a balloon. We also demonstrate the effect of using dried and compressed yeast in the making of bread rolls in a real-life school laboratory environment. Students are also shown how to write up the result of the tests.

Foods for Special Occasions
Food is critical to survival. It keeps us healthy, active and functioning well. But some foods have meaning. As well as providing nutrition, these foods are created and prepared for special occasions. Making these foods requires planning and presentation skills. In this program we examine some of the world’s major social, cultural and religious occasions and the foods that are central to them. Students watching this program will gain a greater understanding of these different foods and why and when they are eaten.
