Eating patterns that focus on limiting saturated fats and promoting the intake of unsaturated fats, like omega-3 fatty acids, support overall health and can reduce the risk of heart disease. However, the consumption of omega-3 as a direct goal of Healthy People 2020 is not specified; rather, they form part of a comprehensive approach to healthy eating. Additionally, increasing physical activity helps reduce obesity, as it leads to more calorie burn, which is in line with the Healthy People 2020 objectives as well as initiatives like the Let's Move!
