This episode brings you a “debate” between Danny Lennon and Dr. Jackson Peos on the utility of intuitive eating. Specifcally, they make a case for and against, respectively, for the position: “Intuitive eating can be recommended eating approach for those with fitness and/or physique goals”. This episode is a Premium-exclusive episode, so you’ll need to be a Premium subscriber to listen to the full discussion but you can hear a preview here.

SNP13: Intuitive Eating Debate – with Jackson Peos, PhD

Discussions about the science of nutrition, dietetics and health. The podcast that educates through nuanced conversations, exploring evidence and cultivating critical thinking. Hosted by Danny Lennon.

Nutrition

Health & Fitness

Contemporary society is witnessing a growing interest in, and embracing of, plant-based diets. Numerous athletes are now gravitating towards such dietary choices, motivated by concerns for health, performance or ethics. Consequently, coaches, nutritionists, and other fitness experts find themselves increasingly tasked with guiding athletes who adhere to plant-based diets. For coaches and trainers, understanding the possible impacts of these dietary preferences on athletes’ objectives is paramount, as is devising dietary plans that optimize their performance. This episode discusses the scientific and practical aspects of supporting athletes who have adopted a vegetarian lifestyle and diet.

SNP29: Athletes & Plant-Based Diets – Evidence & Application in Practice

The Food Frequency Questionnaire (FFQ) stands as a cornerstone in nutritional research, offering valuable insights into dietary patterns and habits over a specified period. Despite its widespread use and established utility, the FFQ has not been immune to criticism, much of which arises from a misunderstanding of its purpose and inherent limitations. At its core, the FFQ is designed to assess the frequency and quantity of food consumption, aiming to capture long-term dietary behaviors rather than precise intake levels. Researchers employ it to investigate relationships between diet and various health outcomes, such as chronic diseases or nutritional deficiencies. However, critics argue that its reliance on self-reported data introduces biases and inaccuracies, leading to potential misestimation of nutrient intake. Additionally, some detractors question the FFQ’s ability to capture sporadic or infrequent dietary choices accurately. Yet, it’s crucial to recognize that the FFQ serves a specific purpose within the realm of nutrition research. While there are no doubt limitations, its strength lies in its ability to capture habitual dietary behaviors over an extended period. Moreover, researchers employ various strategies, such as validation studies and data adjustment techniques, to enhance the FFQ’s reliability and validity. In this episode, world-leading nutrition epidemiologist Dr. Deirdre Tobias discusses the development of the FFQ, the key concepts that are crucial to understand, common criticisms of the FFQ, and how we should evaluate the utility of this tool.

#523: How Trustworthy is the Food Frequency Questionnaire in Evaluating Dietary Intake? – Deirdre Tobias, ScD

Download detailed study notes and episode transcript Go to episode page  About This Episode: “Personalized nutrition” has been promoted as an approach that will improve people’s health by prescribing them specific dietary recommendations based on their own genetic and phenotypic data. The premise is that given we each respond differently to foods, having general dietary recommendations may be doing many people a disservice. And by using an array of personal data, it is now possible to give unique diets that improve health. The early and interesting findings of research in this area was met with much fanfare, and indeed, many companies are now offering commercial direct-to-consumer services based on genetic and physiological testing, followed by “personalized” dietary prescription. Such testing may include genetic tests, microbiome testing, glucose monitoring data, and more. This data is then fed into machine learning algorithms to prescribe dietary recommendations. However, do the marketing claims match the current evidence? Does the “proof” it works that is often cited, actually back up the claims? Do personalized nutrition diets actually lead to improved health outcomes over generic, conventional dietary recommendations? Do personalized nutrition diets lead to better outcomes than standard dietetic/nutrition practice? To answer these questions, we go through the main studies cited in favor of personalized nutrition being superior to typical dietary advice, and see if they indeed support the claims. So is personalized nutrition superior to standard dietary advice? Let’s find out… Note: This was originally a Premium-exclusive episode.

#522: Does Personalized Nutrition Outperform General Dietary Advice?

The relationship between coffee and health is complex, encompassing areas like blood lipids, cardiovascular disease, neurodegenerative diseases, anxiety, and depression. Coffee has an interesting nutrient profile and contains diverse bioactive compounds that influence metabolism. Coffee has a potential impact on cardiovascular disease risk, with mechanisms that highlight potential benefits and some concerns. There may be an impact on blood pressure and blood lipid, but there are important nuances to this. Some research suggests that moderate intake may protect against neurodegenerative diseases like Alzheimer’s and Parkinson’s, with some mechanisms proposed for the observation.  Coffee’s effects on anxiety, depression, and sleep are common talking points and worthy of addressing. The context of the consumption and the individual in question will dictate the likely effects. Ultimately, coffee’s effects on health are influenced by various factors, warranting personalized approaches to consumption. In this episode, Simon Hill puts some questions to Danny Lennon about the impact of coffee on our health.

#521: How Does Coffee Impact Our Health?

While we know that single bouts of exercise can create a short-term energy deficit, do they also influence our hunger levels? And what about long-term exercise training? Could it modify our appetite in ways that help us better control our weight? Recent research suggests that exercise may indeed play a role in appetite regulation. Could exercise modify the subjective and homeostatic mediators of appetite in ways that enhance our feelings of fullness after a meal? One of the most fascinating aspects of this research is the variability in responses between individuals. Why do some people experience changes in appetite and energy intake after exercise, while others don’t? Could factors like adiposity, sex, or habitual physical activity levels play a role? In this episode, Dr. James Dorling of the University of Glasgow helps us delve into the evidence surrounding how factors like adiposity, sex, and habitual physical activity modulate our responses to exercise in terms of appetite, energy intake, and appetite-related hormone responses. About The Guest: Dr. James Dorling is a lecturer in Human Nutrition at the University of Glasgow. Dr. Dorling’s research is broadly focused on three areas: (1) the impact of nutrition and physical activity interventions on obesity-related endpoints and biomarkers of aging; (2) the regulators of appetite and eating behaviours; and (3) the changes in appetite and eating behaviours in response to health interventions. During his PhD, he studied the effects of acute exercise and obesity-related single nucleotide polymorphisms on appetite and appetite-related hormones. Following this, Dr. Dorling joined Pennington Biomedical Research Center where he worked as a postdoctoral researcher. His postdoctoral research principally focussed on the influence of calorie restriction and physical activity on weight, markers of aging, and eating behaviours.
