Intelligent Medicine Radio for May 11, Part 2: What is the best natural sweetener?

Herbal Medicine, Quality Control, and Adulteration Prevention: Mark Blumenthal, founder and executive director of the American Botanical Council (ABC), recounts his entry into herbalism via vegetarianism in 1968, off-grid living, and starting a wholesale herb business in 1974 before shifting to nonprofit education, research, advocacy, and quality control. The discussion covers the evolution from teas and tinctures to standardized extracts, the complexity and synergy of multiple constituents, and how standardization supports quality control and therapeutic consistency. Blumenthal explains ABC’s Botanical Adulterants Prevention Program and its free, peer-reviewed resources addressing global fraud, plus GMP requirements and laboratory methods for identity, contamination, and potency testing. He discusses herbs including ashwagandha, turmeric/curcumin and adulteration risks, maca, nigella, and milk thistle, and outlines ABC resources, HerbClip, and membership options at herbalgram.org.

Dr. Hoffman continues his conversation with Mark Blumenthal, founder and executive director of the American Botanical Council (ABC).

Registered dietitian nutritionist Leyla Muedin discusses a New England Journal of Medicine paper (July 2024, cited via Holistic Primary Care) warning about drug-induced magnesium depletion, especially from diuretics, proton pump inhibitors (e.g., Nexium, Prilosec), and certain antibiotics. She notes magnesium is often not routinely measured despite links between deficiency and cardiovascular, metabolic, and neurological problems, including arrhythmias (AFib, long QT, torsades), endothelial dysfunction, and longer ICU stays. Prevalence estimates range from 7–11% (up to 20%) in hospitalized patients and 2–4% among outpatients, with higher rates among long-term PPI and diuretic users. She reviews symptoms and causes, explains limits of serum magnesium testing, highlights associations with diabetes, alcohol use, low potassium and calcium, and outlines evaluation options and oral repletion approaches, favoring better-absorbed forms like magnesium glycinate over oxide due to diarrhea risk.

Harvard-trained psychiatrist Dr. Georgia Ede is the author of "Change Your Diet, Change Your Mind: A Powerful Plan to Improve Mood, Overcome Anxiety, and Protect Memory for a Lifetime of Optimal Mental Health." She links diet to the mental health crisis and dementia risk. Ede explains that conventional psychiatric training ignored nutrition, and she later incorporated dietary strategies alongside medication and psychotherapy after personal health experiences. She emphasizes focusing on metabolic and nutritional quality—especially stabilizing blood sugar and insulin—rather than simplistic plant-vs-animal messaging. She argues some animal foods are needed for brain nutrients like B12 and EPA/DHA. She discusses ketogenic diets as a way to lower insulin, produce ketones, improve brain energy, and reduce inflammation, citing case reports and a study of hospitalized patients where many improved and 44% reached remission. She critiques nutrition epidemiology as unreliable and outlines three “quiet” dietary tiers: whole-food low-glycemic, ketogenic, and carnivore, plus practical issues like electrolytes and gradual transition.

Dr. Bret Scher, medical director of the Coalition for Metabolic Health, discusses making metabolic health the foundation of medicine amid rising obesity and type 2 diabetes and reports that 93% of Americans have suboptimal metabolic health. Scher defines metabolic health using markers including glucose, insulin, triglycerides, HDL, blood pressure, and waist size, and cites evidence linking insulin resistance to heart disease, stroke, cancer, psychiatric illness, and other complications. They discuss simple self- and lab-assessments (waist-to-height ratio, fasting insulin with glucose/HOMA-IR, triglyceride-to-HDL ratio, CGMs). Scher critiques the Eat Lancet report for assuming one optimal diet, reliance on low-quality nutrition epidemiology, potential nutrient shortfalls, and environmental oversimplification, while supporting newer dietary guidelines that allow lower-carb approaches. Part two covers contradictory nutrition studies, distinctions between low-carb and ketogenic diets, emerging “metabolic psychiatry” and ketogenic therapy for mental illness and cognitive decline, limits and rebound risks of GLP-1 drugs, and Coalition efforts to improve school food and influence policy.
