The 2021 Dietary Guidance to Improve Cardiovascular Health scientific statement provides 10 evidence-based guidance recommendations to promote cardiometabolic health. Some of the recommendations include using liquid plant oils in place of tropical oils (such as palm, palm kernel, or coconut), animal fats (such as lard or butter), and partially hydrogenated fats.

Although the AHA states that it is good to choose plant-based alternatives, meat alternatives are often ultraprocessed, and evidence on their short-term and long-term health effects is limited. Unsaturated fats are preferred, as are lean, nonprocessed meats.

The AHA recommends choosing and preparing foods with little or no salt. Potassium-enriched salts are a promising alternative but are not currently recommended as a supplement.

The AHA recommends coupling dietary changes with at least 150 minutes of moderate physical activity per week, adjusted for the individual's age, activity level, sex, and size.
