Power of Choice Guided activities and material to motivate and empower kids to make healthy food choices in real-life settings, topics include portion control, emotional eating, and individual fitness. (Recently completed collaborative effort with USDA/FNS)

35 Slide 35 1. Education Food Label Content Relevant to Weight Management  Standard reference serving sizes in nutrition facts panel  Facilitates counting calories while choosing nutritious foods, e.g., by comparing vitamins, minerals, and types of fats across products within a calorie range  Nutrient content claims  Based on standard criteria, help consumers make lower calorie choices when they see claims, like "reduced calories", "lite", "low calorie", "calorie free"

36 Slide 36 1. Education Dietary Guidelines 2000 DG’s include attention to healthy BMI, activity, eating sensibly, and portion size Newly formed advisory committee is evaluating the need to update the DG's in 2005

37 Slide 37 2. Regulation/Guidance Labeling/Packaging Effort Research and development (stakeholder interaction, focus groups, and modeling) to develop label modifications or new approaches to labeling conducive to weight management.
