1 Understanding the SACN Report on Carbohydrates & Health FDIN, London, From a Dietary Fibre Perspective Wim Caers Director Regulatory & Government Affairs

2 Conclusions Recognise the huge body of work: 384 pages (>3000 including all separate Chapters!!) New recommendation for a dietary fibre definition UK in line with other definitions worldwide New recommendation for increased DF intake, based upon AOAC analytical methodology Reinforces the fit of DF within a healthy diet, using a variety of food sources UK in line with most broadly used methodology and scope of definition, and allows for better comparison with other countries Main issue: NOT just to increase DF intake to reach the recommended levels BUT how to get there without increasing your total energy intake

3 A new Dietary Fibre Definition S1: There is no universal definition of the term dietary fibre. Dietary fibre should be defined as all carbohydrates that are neither digested nor absorbed in the small intestine and have a degree of polymerisation of 3 or more monomeric units, plus lignin. For extracted natural carbohydrate components or synthetic carbohydrate products to be defined as dietary fibre, beneficial physiological effects, similar to those demonstrated for the naturally integrated dietary fibre components of foods, must be demonstrated by accepted scientific evidence.

4 A new Dietary Fibre Definition Going away from the NSP definition In line with almost all other existing DF definitions Codex Alimentarius (with Footnote 2) - China EFSA & EU - Indonesia FSANZ - Mexico Canada - Japan (US FDA) Dietary fibre and Non-digestible oligosaccharides (including inulin), resistant starch, (polyols) and polydextrose are treated as 2 different categories?

7 A new Dietary Fibre Recommendation & Analytical Methodology From 18g (NSP-Englyst, equals 23-24g AOAC) to 30g/day AOAC ( 16 yrs) Age (yrs) Recommendation (g/day) Actual inatke (g/day Gap % , ,

13 Filling the Gap Nicklas et al, 2011;;

14 Filling the Gap Nicklas et al, 2011;; Increase intake of DF-rich foods: fruits, vegetables, legumes, grain products % Increase in DF containing foods Mean g/d 0 15,7 Increase in kcal 10 16, , , ,5 1042

15 Filling the Gap Nicklas et al, 2011;; Conclusions: Adding additional DF to existing grain-based foods may be a reasonable approach to getting more DF, without increased energy, in the American diet.

Filling the Gap Main Conclusion: The roundtable discussion highlighted the need for both consumer and professional education to improve acceptance for and inclusion of grain-based foods

16 Filling the Gap Main Conclusion: The roundtable discussion highlighted the need for both consumer and professional education to improve acceptance for and inclusion of grain-based foods with added fiber as one strategy for increasing fiber intakes within daily energy goals.

17 Fit with SACN Report Broadened DF definition allows use of wider range of dietary fibres, often without making a compromise on taste Resistant maltodextrin, inulin, polydextrose, SACN acknowledges that (certain) isolated fibres do exert similar beneficial properties as intrinsic fibres Oat bran and isolated β-glucans and lower total cholesterol, LDL cholesterol and triacyl glycerol concentrations (S.11)

18 Fit with SACN Report Evidence given for: DF category Dietary fibre - Legume fibre Insoluble fibre - Cereal fibre Soluble fibre - Oat bran & β-glucans Fruit fibre - Cereal fibre excluding oat Vegetable fibre - Wheat fibre Fruit and vegetable fibre - Non-wheat cereal fibre Higher dietary breakfast cereals - Whole grain bread Total cereals - Whole grains

19 Fit with SACN Report Evidence given for: Non-digestible OS, resistant starch, polydextrose Non-digestible OS (inulin, FOS) - Inulin Fructo-OS - Galacto-OS Arabinoxylan-OS - ND-OS or inulin Resistant starch - Polydextrose Fibre isolates (Annex 5) Psyllium - Pectin Cellulose - Mixed isolated fibres (gums)

20 Fit with EFSA - EC SACN and EFSA approach are clearly not identical E.g. Dietary fibre Promotes regularity Maintenance of normal blood lipid/cholesterol levels Maintenance/balance of normal blood sugar/glucose levels Helps maintain body weight Maintenance of a healthy immune system All non-authorised because of insufficient characterisation of ingredient

21 Fit with EFSA - EC SACN and EFSA approach are clearly not identical E.g. Dietary fibre Faecal weight/transit time Cardiovascular disease Coronary events Stroke Fasting blood lipid/cholesterol levels Fasting blood sugar/glucose levels Helps maintain body weight

22 Fit with EFSA - EC SACN and EFSA approach are clearly not identical E.g. Whole grain Maintenance of normal blood glucose levels Promotes heart health Healthier body weight Regulates blood cholesterol levels Increases satiety All non-authorised because of insufficient characterisation of ingredient

23 Fit with EFSA - EC SACN and EFSA approach are clearly not identical E.g. Whole grain Cardiovascular disease Stroke Hypertension Energy intake Diabetes mellitus Colon cancer Fasting blood glucose levels Fasting blood cholesterol levels

24 Fit with EFSA - EC But there are similarities (Oat & barley) β-glucan Maintenance of normal blood cholesterol levels Reduction of blood glucose rise Lower reduce blood cholesterol Arabinoxylan Reduction of blood glucose rise HPMC Reduction of blood glucose rise Lower reduce blood cholesterol

25 Fit with EFSA - EC But there are similarities Polydextrose Reduction of blood glucose rise Maintenance of tooth mineralisation Non-digestible carbohydrate Reduction of postprandial glycaemic response Conditions of use: Reduced sugar (30%)!! Inulin Maintenance of normal defecation by increasing stool frequency

26 Fit with EFSA - EC But there are similarities Pectin Reduction of blood glucose rise Maintenance of normal blood cholesterol levels Guar gum Maintenance of normal blood cholesterol levels Sugar beet fibre Increase of faecal bulk

27 (Final) Conclusions Widened scope of DF definition From NSP to non-digestible carbohydrates: DP 3 Widened scope will allow food industry to better enrich food with palatable DFs Adjusted (increased) recommended DF intake From 23-24g (= 18g NSP) to 30g Reinforces the fit of DFs from a variety of food sources within a healthy diet and may encourage consumers to actually increase their intake

28 (Final) Conclusions AOAC methodology becoming the standard Englyst not in line with new DF definition Allows for a correct and univocal quantification by industry and authorities Acknowledgement of (certain) isolated fibres to excert similar beneficial effects as intrinsic fibres Isolated oat β-blucans May be a (the) way to allow for an increase in DF intake without simultaneously increase total energy intake

29 (Final) Conclusions These changes will support a better understanding by consumers and will help to make them successful in achieving their good dietary intentions

30 (Final) Conclusions When the consumer is enthusiastic & motivated, we are too!!
