FOR IMMEDIATE RELEASE
American Heart Association's Irresponsible News Release of the Intermittent Fasting StudyRichard Z. Cheng, M.D., Ph.D.OMNS (April 3, 2024) The American Heart Association (AHA) recently released a news report highlighting a poster presentation that suggested an association between an 8-hour time-restricted eating schedule (intermittent fasting) and a 91% higher risk of cardiovascular disease mortality (AHA 2024, Chen 2024). This AHA's news release quickly spread throughout the internet, causing much confusion to the public. However, this preliminary finding has not undergone full statistical analysis or peer review, and the AHA's premature release of such information has been criticized as irresponsible and potentially misleading. There are several issues with the AHA's poster presentation:
A serious scientific study would have all these factors adjusted and the manuscript peer-reviewed before public release. This AHA poster presentation may or may not survive this rigorous publishing process and hence may not be finally published. The AHA's news release of this intermittent fasting study is premature, misleading, bordering pseudo-science and has caused significant confusion and potential damage to the public. The American Heart Association's conflict of interest with big food and drug companies is a significant concern, as it can influence the organization's health recommendations (Lauerman 2016). Newly released documents reveal that the Academy of Nutrition and Dietetics, which endorses various food products, has financial ties with companies like Nestlé, PepsiCo, Hershey, Kellogg's, General Mills, and others (Reed 2022). Similarly, the American Heart Association has received millions from fast food and processed food manufacturers (Kaplan 2017). Major pharmaceutical companies donate huge sum of funds to healthcare organizations, potentially influencing their focus on treatment rather than addressing the root causes of diseases like poor dietary choices (Kaplan 2017). Canella (2015) and Yanamadala (2012) both highlight the potential for industry influence in scientific events and the creation of front groups to oppose government regulation. This influence is further underscored by Mialon (2022), who found that 95% of the U.S. 2020 Dietary Guidelines Advisory Committee had conflicts of interest with the food and pharmaceutical industries. The need for regulation in the training and practices of nutritionists is emphasized by Pereira (2016), while Nestle (2013) and Mozaffarian (2017) discuss the threat to scientific integrity and the role of the food industry in nutrition research. Mendelson (2011) also notes the prevalence of conflicts of interest in cardiovascular clinical practice guidelines. These studies collectively underscore the need for transparency and regulation to mitigate the influence of big food companies on health organizations like the American Heart Association. Numerous studies have demonstrated the potential benefits of intermittent fasting for cardiovascular health, weight loss, metabolic health, brain function, longevity, and even autoimmune diseases and cancer (Sun 2024, Cheng 2024). These studies emphasize the positive impact of intermittent fasting on various aspects of health and well-being. From an evolutionary perspective, human ancestors were routinely on intermittent fasting which seems to bestow survival benefits. I have been practicing intermittent fasting (as part of my integrative and orthomolecular medicine protocol) for myself and have been recommending it to my patients, clients, and audience for more than 10 years with great success (Cheng 2024).
