DeepSummary
The podcast episode focuses on a study that claimed red meat consumption is linked to an increased risk of type 2 diabetes. Dr. Mark Hyman critically examines the study's design, findings, and flaws, arguing that it does not prove a causal relationship between red meat and diabetes. He highlights issues such as reliance on food frequency questionnaires, statistical manipulations, and failure to account for confounding factors like overall diet and lifestyle.
Hyman presents evidence from other studies, including randomized controlled trials and meta-analyses, which suggest that red meat consumption in the context of a healthy diet does not negatively impact glycemic control or inflammatory markers. He emphasizes that the root cause of type 2 diabetes is insulin resistance, primarily driven by excessive consumption of refined carbohydrates, sugar, and ultra-processed foods.
The episode provides strategies to address type 2 diabetes from a functional medicine perspective, such as eliminating ultra-processed foods, refined grains, and sugars, while incorporating high-quality proteins, fiber, fruits, vegetables, and healthy fats. Hyman recommends testing biomarkers to assess insulin resistance and overall metabolic health.
Key Episodes Takeaways
- The study claiming red meat causes type 2 diabetes has significant design flaws and does not prove a causal relationship.
- Evidence from randomized controlled trials and meta-analyses suggests that red meat consumption in the context of a healthy diet does not negatively impact glycemic control or inflammatory markers.
- The root cause of type 2 diabetes is insulin resistance, primarily driven by excessive consumption of refined carbohydrates, sugar, and ultra-processed foods.
- A functional medicine approach to addressing type 2 diabetes involves eliminating ultra-processed foods, refined grains, and sugars, while incorporating high-quality proteins, fiber, fruits, vegetables, and healthy fats.
- Testing biomarkers such as fasting glucose, insulin, A1C, and inflammatory markers can help assess insulin resistance and overall metabolic health.
- Red meat, when consumed as part of a healthy dietary pattern, does not appear to be a significant risk factor for type 2 diabetes.
- Observational studies, while useful for generating hypotheses, cannot prove causation and should be interpreted with caution.
- Confounding variables, such as overall dietary patterns, physical activity, and lifestyle factors, can significantly impact the interpretation of observational studies.
Top Episodes Quotes
- “If red meat, it's processed makes you have a higher risk of diabetes and unprocessed rest meat lower, then if you add them together, you shouldn't have a higher risk when you combine them. So it doesn't make sense.“ by Mark Hyman
- “Overall, red meat intake does not independently influence changes in cardiometabolic disease risk factors in the short term for those who should choose to consume red meat, red meat, as with all other protein rich food sources, should be consumed in the context of a healthy eating pattern, high in fruits and vegetables and whole grains, and within the energy needs to reduce cardiometabolic disease risk.“ by Mark Hyman (quoting a study)
- “If you eat red meat in the context of a healthy diet, there's really no big deal.“ by Mark Hyman
- “Functional medicine is all about root cause. The root cause is something called insulin resistance, and this comes from eating a diet that's high in sugar, refined flour, grains, ultra processed food.“ by Mark Hyman

Recently, a study made headlines linking red meat consumption to an increased risk for type 2 diabetes. It’s no secret that navigating the realm of nutrition has become a challenge for the general public.
That’s why, on today’s Health Bites episode, we’re diving deep into the findings from this study, “Red meat intake and risk of type 2 diabetes in a prospective cohort study of United States females and males,” published in The American Journal of Clinical Nutrition. I unpack the study’s design flaws, inaccuracies, and where the researchers got it straight up wrong.
