Regulations, Interventions and Evaluation of Policies and Plans that Prevent Obesity and related Chronic DiseasesThe Canadian ExperienceHow to Succeed? Mary R. L’Abbé, PhD Director, Bureau of Nutritional Sciences, Food Directorate Health Canada Health and Nutrition Summit, Chile, March 2008
Overall Goal of GS Article 17 “To promote and protect health by guiding the development of an enabling environment for sustainable actions at individual, community, national and global levels that, when taken together, will lead to reduced disease and death rates related to unhealthy diet and physical activity”
Regulations, Intervention and Evaluation of Policies • Who we are, the Regulator's Role • Information for consumers • Dietary Recommendations • Surveillance, research and evaluation
Bureau of Nutritional Sciences, Food Directorate • Only one part of the Health Portfolio which also includes the • Office of Nutrition Policy and Promotion, • First Nations and Inuit Health Branch, • Public Health Agency of Canada, • Canadian Institutes of Health Research, and many other Departments … • The Health Products and Food Branch (HPFB) is Canada's federal authority responsible for the regulation of health products and food by: • Minimizing the health risk factor to Canadians, while maximizing the safety provided by the regulatory system • Promoting conditions that enable Canadians to make healthy choices and providing information so that they can make informed decisions about their health
BNS - Who We Are, What We Do Nutrition Evaluation Division Nutrition Research Division Laboratory Research • Nutritional Molecular Biology Section, • Nutritional Metabolism Section • Method development to support regulations • Laboratory nutrition research • National Reference Laboratory for Canadian Health Measures Survey Nutritional Quality and Safety • Food fortification • novel fibres, sodium, trans Special Purpose Foods • Infant Formulas • nutritional supplements Labelling and Claims • Nutrition labelling • nutrient content claims • health claims • Front-of-pack symbols Surveys Section • food composition databases (Canadian Nutrient File) • survey methodology • national food consumption surveys (CCHS) and nutritional status (CHMS) surveys
GS Recommendations Re: Information for Consumers • Article 40 “Governments should provide accurate and balanced information… (3) Marketing, advertising, sponsorship and promotion … to deal with the marketing of food to children. (4) Labelling (5) Health Claims
(3) Marketing, advertising, sponsorship and promotion to children • In Canada, Food and Drug Act and Regulations apply to labelling and advertising; • Section 5(1) prohibits false and misleading • Does not specifically address advertising to children • Recent developments: • Voluntary industry code adopted in 2007; 1st year progress announced in Feb 2008 • Canadian Parliamentary Standing Committee on Health Report “Healthy Weight, Healthy Kids” March 2007 • Chronic Disease Prevention Alliance of Canada (CDPAC) “Policy Consensus Forum on Obesity and the Impact of Marketing on Children” recommendations for regulations banning the marketing of “unhealthy” foods to children, March 2008 • TV broadcast licences require pre-approval of children's’ advertising by industry self-regulatory board
(4) Nutrition Labelling(5) Claims • 1996: Government of Canada’s Nutrition for Health: An Agenda for Action, identified food label information as means toward healthier eating habits • 1998: Food Directorate undertook a Nutrition Labelling Policy Review • 2000: Minister of Health announced regulations mandating nutrition labelling on virtually all pre-packaged foods • 2002: Nutrition Labelling and claims regulations adopted (Canada Gazette, Part II), mandatory by 2005
Health Claims Nutrient Content Claims Nutrition Labelling (4) Nutrition Labelling(5) Claims • Health Claims: conditions and criteria for authorizing disease risk reduction health claims • Nutrient Content Claims (47): updated criteria and requirements supported by science • Mandatory “Nutrition Facts” table on most pre-packaged foods including declaration of energy and 13 nutrients
(4) “Nutrition Facts” table • Core list of Calories and 13 nutrients always declared. • The nutrient information based on a specified amount of food as sold. • For macronutrients, actual amount in the stated serving of the food is listed. • % Daily Value (%DV) indicates the relative amount of the nutrient in the stated serving. • Optional closed list of 30 additional nutrients.Note: must be declared if subject of a claim or if added.
(4) Nutrient Content Claims - 2 types • Level of a nutrient contained in a food Involves definitions and conditions for using specific terms, limits synonyms: • Free • High, Low • Good source • Light • No added fat … • Comparative Claims compares the nutrient levels and/or energy value of two or more foods • Examples: “reduced”, “less than”, “fewer”, “increased”, “more than”
(5) Health Claims Allowed in Canada • General Health Claims • E.g., “With only 1 gm of fat, this is a healthy choice” • Logos of a “heart”, company or Association sponsored symbols • These are not regulated; just guidelines • Biological Role Claims re: how a nutrient in a food contributes to good health • Acceptable claims for over 20 nutrients in current guidance • E.g., “Calcium aids in the formation and maintenance of bones and teeth” • List of acceptable claims maintained; do not need regulatory authorization • Disease Risk Reduction Claims linking a healthy diet with specific characteristics, to reduced risk of disease • Pre-approval is required to review evidence substantiating claim and regulations required to authorize their use and establish conditions for claim • E.g., “A healthy diet rich in a variety of vegetables and fruit may help reduce the risk of some types of cancer”
Regulating Disease Risk Reduction Health Claims • Statement of the claim is defined in two parts: • Characteristics of the diet associated with the disease risk reduction • Characteristics of the food that make it a suitable part of the diet • Conditions are placed on the food in order to carry the claim • Contains 100 g or less cholesterol per 100 g • Meets the conditions for “free or low” in saturated fats • Conditions are placed on the label • Label shall include the amounts of sats and trans
Current & future work on labelling and claims… • Modernized Framework for Health Claims • Policy consultation released Nov 2007 • Substantiation of Claims • Food/NHP Interface; added bioactives • Managing a Broader Range of Function Claims • Front of Package Claims and Symbols • Eligibility Criteria for Foods to carry Claims; definition of “healthy” foods • Labelling of fresh meats, seafood and poultry, raw fruits and vegetables • High interest by industry associations and health professionals • Restaurant food labelling • Voluntary guidelines (2006). • Same core information and order as required for nutrition labelling • More than 25 major chains representing >40% of establishments • In-store, brochures, websites etc
Canadian Nutrient File (CNF) • Maintained by FD’s Nutrition Surveys Section • Canada’s national reference food composition database • Contains information on 143 nutrients and food components for over 5500 foods • Accessed by governments, practitioners, food industry, academia, etc. • Critical in developing Canada Food Guide • Serves as basis for national and provincial food consumption surveys
Nutrient Value of Some Common Foods • The Nutrient Value of Some Common Foods is an extremely popular condensed, printed version of nutrient information for users who prefer this format. • A new version, free of charge, will be available at the end of March 2008.
GS recommendations re: Surveillance • Article 46 “Governments should invest in surveillance, research and evaluation re:… • Dietary habits • Canada Community Health Survey (CCHS) 2.2 Nutrition, 2004 • Patterns of physical activity • CCHS, CHMS • Nutrition-related biological risk factors • Canadian Health Measures Survey (CHMS), 2008-09 • Biomonitoring, e.g. MIREX - Human breast milk analyses • Nutrient contents of food products • Canadian Nutrient File, 2007 (9th version) • Total Diet Survey
GS - Dietary Recommendations Article 22: States the recommendations for diet for populations and individuals: • achieve energy balance and a healthy weight • limit energy intake from total fats and shift fat consumption away from saturated fats to unsaturated fats and towards elimination of trans-fatty acids • increase consumption of fruits, vegetables and legumes, whole grains and nuts • limit intake of free sugars • limit salt (sodium) consumption from all sources and ensure that salt is iodized.
Eating Well with Canada’s Food Guide • Updated Food Guide released in Feb 2007 following 5-year review • Points to the Nutrition Facts table as a tool for comparing the nutrient content of foods • Key message: Choose products containing less fat, saturated fat, trans fat, sugar and sodium • Promotes consumption of fruits, vegetables and legumes, whole grains and nuts
Other dietary interventions for Canadians… • Trans fat • Sodium
Trans fat intake in 1995 - Canada vs. other countries 8.4 g/day Hulshof et al. (1999); Zhou et al.(2003); Ratnayake and Chen (1995)
Trans-fatty acid content of human milk samples from various countries Canada 1995: 198 samples collected from all 9 provinces of Canada (Ratnayake Lipids ’95) Canada 1999: 103 samples from BC (Innis AJCN ‘99)
Canada’s Trans Fat Intakes • During the mid1990’s, one of the highest intakes in the world (8.3 g per day) • In 2005, Health Canada estimated an average intake of 4.9 g (2.2% energy) • Influenced by consumer awareness and mandatory trans fat labelling regulations introduced in 2002 and mandatory by 2005. • Still above current recommendations of WHO. Intakes should be <1% of total energy (2.2 to 2.7g)
Estimated trans fat intakes in Canada in 1995 and 2005 WHO Recommended Level 8.3g 4.9g 2-2.7g
The Task Force released its final report June 2006 • Co-Chairs: • President, Heart and Stoke Foundation of Canada • Director, BNS, Health Canada Members: • Balanced representation of academics, health and consumer NGOs, industry and government http://www.hc-sc.gc.ca/fn-an/nutrition/gras-trans-fats/tf-ge/tf-gt_rep-rap_e.html
Trans Fat Task Force Final Report June 2006 • Limit the TFAs in foods through regulation • Vegetable oils and soft, spreadable margarines – 2% of total fat content • All other foods – 5% of total fat content • Also provided information on healthier alternatives for each sector of the food industry (e.g., baking, frying etc.) • Would enable Canadians to achieve limits recommended by WHO in Global Strategy Diet, Physical Activity and Health (WHO, 2004)
Ministerial AnnouncementJune 20, 2007 • HC would adopt the TFTF’s recommendations on TFA limits • Industry was given 2 years to reduce TFA • If significant progress has not been made, HC will develop regulations • Commitment to publish results of trans fat monitoring program (TFMP) on HC website • Consistent with Government’s plan to modernize food safety system: • “It should provide new and better information on food risks in the Canadian marketplace and involve industry and Canadians to address those risks.” (Food and Consumer Product Safety Action Plan)
Release of first data set - December 20, 2007 • Release included data on food samples from 2005, 2006, and spring 2007. • Included: • pre-packaged foods: • cookies, crackers, frozen potato products (ex. frozen french fries), frozen chicken strips/nuggets, granola bars, and muffins • foods from restaurant and fast food chains: • chicken strips/nuggets, donuts, fish products, french fries, miscellaneous fast foods (ex. apple turnovers and hashbrowns), muffins, and onion rings
Highlights from first data set • in all food categories targeted, saw success in reducing level of TFA • in many cases this was achieved by using healthier alternatives and not increasing levels of saturated fats • it was noted that results from lab analyses were consistent with information provided in the Nutrition Facts table on the sampled products food labels
Snapshot of pre-packaged foods meeting the 5% limit in 2006 * The foods that were sampled represented the top selling brands for each food category and accounted for more than 80% of sales within that food category.
Snapshot of foods from major fast food chains meeting the 5% limit in 2007 ** The foods that were analyzed were sampled from the major fast food chains.
Example: fast foods french friespartial data 1 TFA = trans fat, 2 SFA = saturated fat
Focus on Sodium in Canada • Mandatory Nutrition Labelling Regulations (Dec 2002) • Sodium one of the core nutrients • Six nutrient claims related to sodium and salt such as “low in sodium”, “reduced in sodium” “salt-free” … • Health claim indicating that a healthy diet containing foods high in potassium and low in sodium and reduced risk of high blood pressure • IOM Dietary Reference Intakes for the electrolyte nutrients, including sodium (2004) • Harmonized nutrient recommendations for Canada and the US. • Indicates that the majority of Canadians exceed the UL for sodium • ‘Framework for Cooperation on Chronic Diseases Agreement’ (Jan 2005) - signed by Federal Minister of Health • Includes implementation of Global Strategy on Diet, Physical Activity and Health • Forum: Dietary sodium as a public health issue for Canadians (March 2007) • general agreement that it is time to take action to reduce sodium intake
Sodium intake in Canada 1,2 From the 2004 Canadian Community Health Survey (CCHS 2.2) – Nutrition1 2excludes salt added in cooking and at the table) 1Health Reports, Statistics Canada 18(2): 47-52, 2007.
Multi-stakeholder Working Group (WG) • Formation of WG: Announced by Minister of Health October 2007 • Mandate: To develop, implement and oversee a population-health strategy for the successful reduction of the sodium content of the diets of Canadians • Strategy: To help Canadians maintain and improve their health by developing a strategy for reducing dietary sodium intake by Canadians through three pronged approach: • Education/consumer awareness • Guided voluntary reduction of sodium levels in processed food products and foods sold in food service establishments • Research • 1st meeting held March 2008
Work Underway • Detailed analysis of food sources of sodium • Data gathering process on work underway re: • Programs to educate/inform consumers and health professionals on sodium, blood pressure and health, • Industry programs to voluntarily reduce sodium levels in processed foods and foodservice foods, • Research on: • consumer’s perspective re sodium as a risk factor in hypertension and re sodium reduction efforts • how taste mechanisms factor into food choices with respect to sodium • technical challenges/solutions associated with reducing sodium levels in the food supply.
Sodium WG Steps • Development of strategic framework: (first year) • Develop a Strategic Framework that includes goals, action plans to guide implementation and methods of assessment to determine success • Implementation Stage: (April, 2009 - onwards) • The Multi-Stakeholder Working Group will oversee implementation and monitor progress according to timelines and methods of assessment outlined in the Strategic Framework.
