Sigma Nutrition Radio ·

2025/06/24

For decades, dietary guidelines—and the Food Pyramid in particular—have been at the center of heated debates and considerable controversy. These guidelines have often been accused of being influenced by industry interests, oversimplifying nutritional nuance, or even directly contributing to rising obesity and metabolic disease rates. In this episode, we critically assess common claims surrounding the Food Pyramid, including whether it was truly shaped by vested industry interests, if it encouraged

Inflammation has become a nutrition buzzword, often used in extreme or misleading ways. This episode aims to clarify what inflammation is, how it relates to diet and health, and whether specific foods truly provoke inflammatory responses in the body. The episode provides a nuanced, evidence-based look at inflammation and diet.

2025/06/10

GLP-1 receptor agonists have changed the landscape of obesity treatment, offering levels of weight loss once thought unattainable without surgery. But what happens after the weight is lost? And can we really talk about success without talking about maintenance? While much of the public discourse fixates on dramatic weight loss numbers, the harder question is what comes next. Can lifestyle interventions alone sustain weight loss after GLP-1 cessation? How do metabolic adaptations and behavioral

2025/06/03

Zinc is an essential micronutrient that often flies under the radar, despite being vital for hundreds of enzymes and transcription factors involved in immunity, antioxidant defense, and DNA repair. A surprisingly large segment of the population may not get enough – an estimated 10% of U.S. individuals consume less than half the recommended zinc intake, putting them at risk of deficiency. In this episode, Prof. Emily Ho discusses how even mild zinc insufficiency can impair immune function, promote

2025/05/27

In this episode, we take a deep dive into the commonly held belief that protein is the most satiating macronutrient. It’s an idea that shows up frequently in both clinical guidance and popular nutrition discourse: if you want to feel fuller, eat more protein. But how robust is that claim when you drill into the details of the evidence? To explore this, Alan and Danny examine the complex interplay between protein intake, satiety, and energy intake. We look at both historical and recent literature,

Global food systems have been increasingly subjected to financial speculation, leading to adverse consequences for growers, consumers, and public health. But what are the systemic vulnerabilities that impact food security, equitable access to nutritious food, and the broader socio-political frameworks influencing these outcomes? Understanding the financial mechanisms shaping food production and distribution is highly relevant for health professionals, policy makers, and researchers concerned with

2025/05/13

Seed oils have recently become a hotly debated topic in nutrition, fueled by sensational claims on social media. In this episode, the central theme is examining whether seed oils are truly harmful or if they’ve been unjustly demonized. The discussion tackles prevalent claims – that seed oils drive inflammation, oxidation, and chronic disease – and compares them against the current scientific evidence. This is highly relevant to nutrition science and clinical practice today, as many patients and

#562: How to Detoxify Yourself – Quack Asylum Special

2025/05/06

In this Quack Asylum episode, Danny and Alan critically examine the claims surrounding “detoxification protocols” – specialized diets, cleanses, or supplements marketed to eliminate toxins from the body for better health. The central theme is whether these detox plans actually improve health outcomes or if they’re built on pseudoscience and fear. Many alternative health proponents argue that modern life exposes us to countless toxins that accumulate in our bodies, causing chronic diseases, and thus

2025/04/29

Emulsifiers are a ubiquitous component of the modern food supply, found in everything from salad dressings and dairy products to pastries and sauces. Traditionally regarded as safe by regulatory agencies, emulsifiers play a vital role in enhancing the texture, stability, and shelf-life of countless processed foods. Yet, in recent years, emerging research has prompted a reevaluation of this assumption, raising intriguing questions about whether regular consumption of these additives might have

Nutrition is increasingly being considered as a modifiable factor that may influence neurodevelopmental outcomes. While severe deficiencies in certain nutrients are known to have dramatic effects, there is growing interest in the potential impact of more subtle insufficiencies — particularly during critical windows such as pregnancy, infancy, and early childhood. In conditions like ADHD, dyslexia, and autism spectrum condition (ASC), questions have been raised around whether specific nutrients may

The intersection of nutrition, dermatology, and skin health is an area of growing interest, yet one that remains riddled with misinformation and oversimplified claims. The influence of dietary patterns, specific nutrients, and lifestyle factors on conditions such as acne, eczema, psoriasis, and skin aging has been widely debated, with varying levels of evidence supporting different interventions.

Discussions around ultra-processed foods (UPFs) and their role in public health have gained significant traction in recent years. While some advocate for categorizing and regulating these foods due to their potential negative health effects, others argue that such classifications can oversimplify the issue and detract from more actionable dietary changes. In this episode, Dr. Duane Mellor, a registered dietitian and researcher, joins us to explore the complexities of the UPF debate. Rather than

Sleep is one of the most critical yet often overlooked components of health, performance, and overall well-being. Poor sleep quality or insufficient sleep can disrupt circadian rhythms, impair glucose metabolism, and alter hunger signals, leading to increased food intake, reduced insulin sensitivity, and other undesirable outcomes. In this episode, we bring together expert discussions from some of the leading researchers in sleep science, to explore what defines high-quality sleep, the mechanisms

There is research suggesting that industrialization has significantly altered the composition of our gut microbiota, with certain microbial species now absent in many industrialized populations. Given the known associations between gut microbiome diversity and health, researchers have begun investigating whether restoring lost microbial species and adopting dietary patterns similar to those of non-industrialized populations could lead to measurable health benefits. In a newly-published study, the
