the issue
The issue
  • 30% of calories are from foods that tend to be low in micronutrients
  • Significant groups of adults and children are low in key nutrients, risking deficiency
  • Some nutrients, e.g. omega-3s, vitamin D, iron and selenium are only present in limited numbers of foods
only some consumers are motivated to change their diets

role of fortified products and supplements
Role of fortified products and supplements
  • Boost what consumers already like to eat or find acceptable
  • Take care to fortify where appropriate (chocolate bars with vitamin D!)
  • Supplements only taken by 25% of consumers – room for improvement
  • Consumers prefer ‘natural’ sources of nutrients
