DLM-SF: Guideline Overview (2023)

Guideline Title 
Saturated Fat Evidence-Based Nutrition Practice Guideline (2021-23) 

Guideline Narrative Overview 


According to the World Health Organization, cardiovascular disease (CVD) is the leading cause of death worldwide.1 In 2019, 17.9 million people died from CVD. Atherosclerosis is the usual cause of CVD, including coronary heart disease (CHD), cerebral vascular accident, and peripheral arterial disease.2 Atherosclerosis is the hardening and narrowing of arteries caused by cholesterol-rich plaques.  Most CVD can be prevented by addressing behavioral risks, such as consumption of an unhealthy diet.1 

Health organizations have recommended decreased saturated fat intake to reduce the risk of CVD since the 1970s.3 The rationale behind reducing saturated fat intake is to decrease blood levels of low-density lipoprotein cholesterol (LDL-C), 4 which is a causal factor for atherosclerotic CVD.5-7 The 2021 Dietary Guidance to Improve Cardiovascular Health8, the 2019 American College of Cardiology/American Heart Association (ACC/AHA) Guideline on the Primary Prevention of Cardiovascular Disease, 9 the National Lipid Association (NLA) Recommendations for Patient-Centered Management of Dyslipidemia-Part 1 and Part 2, 10, 11 and the 2020-2025 Dietary Guidelines for Americans (DGAs)12 recommend intake of a dietary pattern low in saturated fat. However, within the past decade, a public health debate has emerged on the association between saturated fat intake and CVD.13, 14 The results of some systematic reviews of observational studies showed no association between saturated fat intake and CVD.16, 17 One argument against reduction of saturated fat intake for CVD prevention is that available studies are flawed due to their inability to control for other dietary variables that may change with reductions in saturated fat (e.g., increased intake of unsaturated fats), and that guidelines should focus on whole foods rather than specific nutrients. 

Healthcare professionals, particularly registered dietitian nutritionists (RDNs), need clear evidence-based resources to provide quality care. RDNs are food and nutrition experts that utilize the best available evidence to translate it into medical nutrition therapies, dietary recommendations, and public health messaging.18 There is a need for systematic reviews of the evidence that evaluates not only the association between amount of saturated fat intake, but also known sources of saturated fat intake and cardiovascular (CV) outcomes.

Guideline Development

The Saturated Fat Evidence-Based Nutrition Practice Guideline (EBNPG) is meant to inform shared decision-making for RDNs and healthcare professionals, along with their patients and clients, in acute, ambulatory, or public health settings on saturated fat intake to prevent or manage CVD. This EBNPG may also help inform public health messaging to improve CV health. The intended population is adults ≥ 18 years of age within the general population. The scope of the systematic review and guideline was not limited by gender or sex, race, ethnicity, anthropometrics, or presence of co-morbidities. This Saturated Fat EBNPG is for individuals living with and without CVD, and the scope was not limited to adults with disorders of dyslipidemia. This EBNPG does not apply to children <18 years of age.  

The research question that guided this EBNPG was: In adults, what is the association of saturated fat intake, replacement of saturated fat intake, and sources of saturated fat intake on CVD and CVD risk factors?  When feasible, sub-analyses were conducted for populations with or without CVD.  In the event there were no differential results between populations, results for the separate populations were merged.  

Topics addressed in this EBNPG include:

  • Amount of Saturated Fat Intake
  • Replacement of Saturated Fat Intake
  • Sources of Saturated Fat Intake

The number of supporting documents for these topics is:
Recommendations: 3
Conclusion Statements: 53
Evidence Summaries: 49
Article Worksheets: 37

Academy guidelines are revisited every five years. An expert workgroup will be convened by the Workgroup Selection subcommittee of the Council of Research (COR) to determine the need for new and revised recommendations based on the available science. The process includes:
Conduct a scoping review to identify new research published since the previous searches were completed. Updated inclusion/exclusion criteria and search terms may be warranted.
Review to determine if the update will include modifications to recommendations and compare them to the earlier version of the guidelines, or development of new recommendations.
