DRVs – Dietary Reference Values, RNIs and GDAs – now called RIs

Our daily needs for nutrients is different, but the DRVs and RNIs are the recommended amounts for the average person.

  • 10-20% of our daily calories should come from protein.
  • Less than 10% of our daily calories should come from saturated fat.
  • 60-70% of our daily calories should come from monounsaturated fat and carbohydrates.
  • 50-55% of our daily calories shoud come from carbohydrates.

We’ve created a Help sheet to explain the terms DRV, RNI and GDA which are also found in the Glossary section of the program.

What subjects can use the Nutrition Program?

The main subject areas using this program are Food Technology and Home Economics.

BUT – there are many other subjects and school areas which study nutrition, recipes, meals and diets, and their students could share your extra users.

1. Healthy Schools Initiative – use the program to look at school meals, tuck shop food, student diets.

2. School Meals – by September 2009, your school meals must meet government guidelines for nutritional standards. Our program provides the facility to check the meals.

3. Licence to Cook – analyse the recipes used on this course to see how healthy they are.

4. Hospitality, Leisure and Tourism courses – they need to analyse menus and provide healthy food.

5. Health and Social Care – BTECs and others learn about diet and health

6. PSHE – teaching about diet and health

7. Science – needed for KS3 and KS4 where they learn about balanced diets and nutrients

8. Physical Education and Sport – the GCSEs look at healthy eating and diet analysis and want students to do practical tasks.

9. ICT and Maths – both subjects need to use real data that is meaningful for students – and students really want to know if their diet is OK. There is a lot of Maths in the program and in my experience, students can’t understand the meaning of % and bar charts!
