What You'll Learn
Education on nutrition and dietary practices
At the governmental level, the World Health Organization (WHO) has developed various strategies and guidelines to support healthy diets. The "WHO Global Strategy on Diet, Physical Activity, and Health," adopted in 2004, calls for action from governments and other stakeholders to promote healthy diets and physical activity. WHO has also developed region-specific tools, such as regional nutrient profile models, to guide countries in implementing marketing recommendations for foods and non-alcoholic beverages aimed at children.
In the United States, the Dietary Guidelines for Americans provide comprehensive advice on nutrition and health, offering guidance to policymakers, healthcare providers, and nutrition educators. These guidelines are updated every five years to reflect advancements in nutrition science. The Healthy Eating Index, created by the USDA's Center for Nutrition Policy and Promotion, is another tool that measures how well American diets conform to recommended healthy eating patterns.
Nutrition education in schools is crucial for helping young people develop healthy eating habits. The Centers for Disease Control and Prevention (CDC) emphasizes the importance of integrating nutrition education into the curriculum, aligning it with national health education standards. Farm-to-school programs, gardening initiatives, cooking lessons, and field trips are all effective ways to engage students and enhance their knowledge about nutrition, agriculture, and healthy food choices.
Additionally, healthcare professionals play a vital role in promoting nutrition education. There is a growing recognition of the need to integrate nutrition and physical activity education more effectively into the training of healthcare professionals. This includes incorporating core topics such as energy balance, the role of specific nutrients, malnutrition, and the role of nutrition in disease prevention and treatment. By staying up-to-date with the latest evidence-based practices, healthcare providers can guide patients toward healthier dietary choices and improve health outcomes.
In conclusion, education on nutrition and dietary practices is essential for fostering healthy lifestyles. By integrating nutrition education into schools, healthcare professional training, and public health initiatives, individuals can make more informed choices about their dietary habits, ultimately improving their overall health and well-being.

Standards for healthy, nutritious, safe, and affordable foods
Governments play a crucial role in establishing a healthy food environment that enables citizens to adopt and maintain healthy dietary practices. The World Health Organization (WHO) has developed several strategies and guidelines to promote healthy, nutritious, safe, and affordable foods.
The WHO's "Global Strategy on Diet, Physical Activity, and Health," adopted in 2004, calls on governments, international partners, the private sector, and civil society to take action at global, regional, and local levels to support healthy diets and physical activity. This strategy includes recommendations on the marketing of foods and non-alcoholic beverages to children, providing guidance for countries to design and improve policies that reduce the impact of marketing unhealthy food choices to children.
The WHO also emphasizes the importance of creating coherence in national policies and investment plans, including trade, food, and agricultural policies. This involves providing incentives for the production and sale of fresh fruits and vegetables, reducing the production of processed foods high in saturated fats, trans-fats, free sugars, and salt/sodium, and encouraging the reformulation of food products to reduce these harmful ingredients.
Additionally, the WHO recommends implementing standards to ensure the availability of healthy, nutritious, safe, and affordable foods in pre-schools, schools, public institutions, and workplaces. This includes exploring regulatory instruments such as nutrition labelling policies and economic incentives to promote healthier choices. Transnational, national, and local food services should be encouraged to improve the nutritional quality of their foods, ensuring the availability and affordability of nutritious options, and reviewing portion sizes and pricing.
Furthermore, the WHO promotes the importance of appropriate infant and young child feeding practices. This includes implementing the International Code of Marketing of Breast-milk Substitutes, promoting and protecting breastfeeding, and providing accurate and standardized nutrition labelling to ensure healthy dietary practices from the earliest stages of life.

Taxation and subsidies for healthy food choices
Millions of deaths each year can be attributed to poor diets, and these numbers are rising. These deaths are preventable, and one strategy to encourage consumers to make healthier choices is through fiscal policy, such as subsidies or taxes.
The World Health Organization (WHO) has developed the "WHO Global Strategy on Diet, Physical Activity and Health", which calls on governments, the private sector, and civil society to take action at global, regional, and local levels to support healthy diets and physical activity. This includes creating coherence in national policies and investment plans to promote a healthy diet and protect public health. For example, policies can provide incentives for producers and retailers to grow, use, and sell fresh fruits and vegetables, while reducing incentives for the food industry to produce processed foods high in saturated fats, trans fats, free sugars, and salt/sodium.
One way to achieve this is through taxation and subsidies. Taxation can be used to reduce the selection of unhealthy foods, while subsidies can be used to increase the selection of healthy foods. For example, a tax on sugar-sweetened beverages or a subsidy for fruits and vegetables could be implemented. The combination of these two approaches offers a balanced and evidence-based approach, as it incentivizes healthier options while still allowing for consumer choice. It also minimizes the regressive nature of taxation alone, as individual food costs could decline with healthier choices in this system.
However, there are challenges to implementing food taxes and subsidies. Firstly, it can be politically challenging and difficult to implement food taxes, especially when they impact a broad range of industries. Secondly, it is complex to estimate the health and health system expenditure effects of food taxes and subsidies, as it requires integrating evidence on how changes in food prices affect purchasing and consumption patterns, as well as how changes in food intake impact dietary risk factors and disease incidence rates. Additionally, there may be systemic barriers for individuals trying to make healthier food choices, such as access to grocery stores or knowledge about healthy eating.
Despite these challenges, the potential benefits of taxation and subsidies for healthy food choices are significant. The large magnitude of health gains and cost savings from these policies warrants serious policy consideration. For example, Mexico implemented an 8% tax on non-essential, energy-dense foods in 2014, which resulted in a 6.0% reduction in the purchasing of these foods. While more time is needed to see the full impact of these policies, they have the potential to improve public health and reduce healthcare costs associated with diet-related chronic diseases.

Food environments and government policies
Food environments and the policies that govern them are crucial in shaping population diets and promoting healthy dietary practices. Governments play a pivotal role in creating healthy food environments, and various strategies can be employed to achieve this goal:
Firstly, coherence in national policies is essential. This includes aligning trade, food, and agricultural policies to incentivize the production, use, and sale of fresh fruits and vegetables while reducing incentives for the food industry to produce and market processed foods high in saturated fats, trans-fats, free sugars, and sodium. Encouraging the reformulation of food products to reduce these harmful substances is also a key aspect of creating a healthy food environment.
Secondly, implementing recommendations on the marketing of foods and non-alcoholic beverages to children is vital. Governments should aim to protect children from unhealthy food marketing and create healthy school food environments. This can be achieved by setting standards for nutrients in processed foods, subsidizing fruits and vegetables to make them more affordable, and taxing unhealthy foods and beverages.
Additionally, promoting local farmers' markets through zoning policies, government subsidies, and public-private partnerships can increase access to fresh produce. This also supports local agriculture and provides communities with healthier food options. Furthermore, addressing the global spread of knowledge, technology, and culture, which has contributed to the rise in overweight populations, is crucial. Policy-makers should navigate international trade laws and agreements to balance the availability of healthy and unhealthy foods.
Moreover, establishing strong nutrition standards and healthy food policies for public facilities and government buildings is essential. Healthy foods should be made more available, accessible, and affordable in these settings, while less healthy options should be restricted. Providing access to free water in government buildings and limiting the availability of sugar-sweetened beverages are also recommended strategies.
Lastly, physical activity plays a role in maintaining a healthy weight. Governments can develop and implement policies that encourage physical activity alongside healthy dietary practices to create a holistic approach to improving the health of their citizens.

Scientific evidence and community partnerships
Community partnerships are vital in promoting healthy eating and lifestyle changes. Agencies and organizations can collaborate to improve access to nutritious food and knowledge about healthy dietary practices. For example, a network analysis of community partnerships in Michigan examined the Supplemental Nutrition Assistance Program Education (SNAP-Ed) and the Expanded Food and Nutrition Education Program (EFNEP). These programs target limited-resource communities and provide nutrition education and skills to promote healthy lifestyles. The success of these programs relies on collaboration with other community organizations and agencies, demonstrating the importance of community partnerships in reaching and impacting the target audience.
The effectiveness of community partnerships is enhanced when different agencies share information, resources, and collaborative efforts. This coordinated approach can better address the complex mix of risk factors, including poor dietary habits, physical inactivity, and financial strain, that vulnerable populations with limited resources often face. Agencies categorized as K-12 schools, early childhood centers, health-related agencies, and social resource centers, among others, can work together to improve dietary behaviors and health outcomes.
Community-based organizations, public health practitioners, and policymakers should consider "real-world" settings when adopting evidence-based policies and programs. Dietary policies should be implemented in conjunction with community partnerships to address the multifaceted nature of dietary behaviors and their impact on cardiovascular disease (CVD) outcomes. Community-partnered research and systems science can be utilized to examine the equitable implementation of evidence-based dietary policies and improve health outcomes.
