  1. Towards a healthier Britain Dr Carrie Ruxton Registered Dietitian Nutrition Communications

  2. Plan of talk • What are we eating today? • Evidence from the NDNS • Hot nutrients for 2011 • Role of fortified products and supplements

  3. What are we eating today?

  4. 30% of calories from nutrient-poor foods and drinks 30% of calories from treats, alcohol, soft drinks, chips and crisps Source: NDNS (2010) 19-64 years

  5. Similar picture in children 32% of calories from treats, soft drinks, chips and crisps Source: NDNS (2010) 11-18 years

  6. Fruit and vegetable intake improving in adults but not in children Source: NDNS (2010) and SACN reports

  7. Half of adults overweight or obese 1 in 5 children overweight Deficiency amongst plenty?

  8. Half of women have inadequate selenium intakes 1 in 5 pre-schoolers have low iron stores Half of adults overweight or obese 1 in 5 children overweight Why does only one side of equation get our attention?

  9. Proven role of nutrients in health Source: EFSA opinions on Article 13 claims, 2010

  10. Evidence from the NDNS

  11. Men and women

  12. Average intakes of vitamins and minerals seem OK, probably influenced by fortified foods NDNS (2010) Adults

  13. But averages mask adults with poor intakes NDNS (2010) Adults Source: NDNS (2010) Adults

  14. EU RDA for adults < 50 years 71% men + 78% of women below RDA Most adults have low vitamin D intakes NDNS (2003) Adults

  15. 25% of adults deficient in winter months 25-hydroxy vitamin D <25 nanomoles/litre Source: National Diet & Nutrition Surveys (2000, 2003)

  16. Children and teens

  17. Younger children doing better on average NDNS (2010) Children

  18. But closer examination reveals the issues Intakes of iron, magnesium and selenium particularly worrying NDNS (2010) Children

  19. Teenage girls most at risk from deficiency NDNS (2010) Children

  20. Most children have low vitamin D intakes 94% boys + 97% of girls below EU RDA of 5 micrograms/day Source: NDNS (2000) Children

  21. Diets have improved little over the years Iron Folate Calcium Vitamin D* * EU labelling RDA of 5 micrograms used

  22. Where are they going wrong? NDNS (2010) Girls

  23. Key nutrients Men • Selenium • Potassium • Magnesium • Zinc • Vitamin A • Vitamin D Women • Selenium • Potassium • Magnesium • Iron • Calcium • Vitamin D • Children • Selenium • Potassium • Magnesium • Iron • Calcium • Vitamin D • Zinc • Folate • Iodine

  24. What are we missing? Iodine Potassium Iron Zinc Vitamin D Folate Vitamin A Magnesium Calcium Selenium

  25. Hot nutrients for 2011 • Vitamin D • Selenium • Omega 3 • Flavonoids

  26. Vitamin D – 90% from sunshine

  27. But diet plays a role 5 to 22 mcg/portion 0.02 to 1 mcg/egg 5 to 10 mcg/tsp

  28. Why are we interested? Mortality Bone health Cognitive function Cancer Heart disease Immune function Diabetes Cell aging Infection Good Moderate Emerging

  29. Selenium • Essential trace element (Se) • Antioxidant • Stored in the body but topped up by our diet

  30. Where do you get it?

  31. Antioxidant Supports fertility Anti-ageing Se Immune function Heart health Mood? Why are we interested?

  32. Are we getting enough? UK rec 60-75 μg/d Selenium intake μg/d MAFF (1999), BNF (2001), Jackson et al (2003)

  33. Omega-3s – still current • Marine foods or supplements remain the best sources of EPA/DHA • Vegetable omega-3s ‘don’t count’

  34. Why are we interested? Immune function Omega-3 Heart health already known IQ in children Less depression? Stress relief Anti-ageing

  35. Omega-3 and the lifecycle Higher IQ Less allergy Brain function DHA EPA Better behaviour? Maintain brain function Less stress

  36. Flavonoids

  37. Why are we interested? Heart disease Oral health Weight management Stroke Cognitive function Blood pressure Cancer Diabetes Good Moderate Emerging

  38. 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

  39. healers disciples investors managers strugglers unmotivateds health involved unmotivated Only some consumers are motivated to change their diets healthinvolved unmotivated Source: Design Bridge

  40. 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
