Consumers are often confused about nutrition research findings and recommendations. As content experts, it is essential that nutrition scientists communicate effectively. A case-study of the history of dietary fat science and recommendations is presented, summarizing presentations from an Experimental Biology Symposium that addressed techniques for effective scientific communication and used the scientific discourse of public understanding of dietary fats and health as an example of challenges in scientific communication. Decades of dietary recommendations have focused on balancing calorie intake and energy expenditure and decreasing fat. Reducing saturated fat has been a cornerstone of dietary recommendations for cardiovascular disease CVD risk reduction. However, evidence from observational studies and randomized clinical trials demonstrates that replacing saturated fat with carbohydrates, specifically refined, has no benefit on CVD risk, while substituting polyunsaturated fats for either saturated fat or carbohydrate reduces risk. A significant body of research supports the unique health benefits of dietary patterns and foods that contain plant and marine sources of unsaturated fats. Shifting dietary recommendations to focus on food-based dietary patterns would facilitate translation to the public and potentially remedy widespread misperceptions about what constitutes a healthful dietary pattern. The way consumers obtain nutrition information has changed substantially in the past two decades.
Whole-fat dairy, unprocessed meat, eggs and dark chocolate are SFA-rich foods with a complex matrix that are not associated with increased risk of CVD.

Recent results suggest that Helicobacter pylori present in stomach contents but not necessarily within the mucus barrier should be rapidly killed by the millimolar concentrations of fatty acids and monoacylglycerols that are produced by preintestinal lipases acting on suitable triacylglycerols, such as those present in milk fat Lauric acid is also effective as an anticaries and antiplaque agent This will require modification of existing foods and changes in policies to improve health, which in turn will require integration of nutrition needs with economic growth and development; agriculture and food production, processing, and marketing; health care and education; and changing of lifestyles and food choices by individual consumers. In practice this means replacing red and processed meat and high fat dairy with fish, nuts, and seeds, and replacing animal fats such as butter and lard with vegetable oils such as corn, sunflower, soy, rapeseed, or olive oils.
