Sugarless: Dr. Nicole Avena on Hidden Sugars, Brain Addiction, and Practical Steps to Cut Back: Neuroscientist and author Dr. Nicole Avena reveals sugar’s pervasiveness and health impacts, drawing on her book “Sugarless: The Seven-Step Plan to Uncover Hidden Sugars, Curb Your Cravings, and Conquer Your Addiction.” Avena explains how modern industrialized, highly processed foods—many containing added sugars—have transformed innate preferences for sweetness into harmful overconsumption linked to obesity, diabetes, cardiovascular disease, non-alcoholic fatty liver disease, and possible dementia via insulin signaling changes. She discusses research showing sugar can stimulate dopamine reward pathways similarly to drugs and that prenatal exposure may alter offspring metabolism, preferences, and sensitivity to drugs/alcohol. For solutions, she discourages strict “cold turkey” approaches due to hidden sugars and relapse psychology, emphasizes inventorying sources and triggers, starting with eliminating sugar-sweetened beverages and sugary coffee drinks, improving breakfast, choosing protein/fat-based snacks, and viewing alternative sweeteners as a temporary crutch; she also notes diet changes can improve mood stability and reduce anxiety.

Functional Diagnostic Nutrition: Using Saliva Testing, Food Sensitivity Labs, and Lifestyle to Find Root Causes: Reed Davis, Board Certified Holistic Health Practitioner (HHP) and Certified Nutritional Therapist (CNT), is founder of Functional Diagnostic Nutrition (FDN). He discusses using functional testing alongside conventional care to uncover “dysfunction” when standard labs appear normal. Davis describes assessing adrenal and metabolic stress via saliva testing for circadian cortisol patterns, cortisol-DHEA balance, sex hormones, secretory IgA, and melatonin, emphasizing clinical correlation and individualized “studies of one.” He outlines an approach targeting multiple “healing opportunities” (H-I-D-D-E-N: hormones, immune, digestion, detoxification, energy, nervous system) and applying D-R-E-S-S (diet, rest, exercise, stress reduction, supplementation) rather than relying on supplements alone. A case example links chronic hives, medication-related weight gain, and food triggers identified through additional testing, including the Mediator Release Test. The discussion also covers stress-driven gut dysbiosis, digestion decline, and EFT tapping for stress-related symptoms, and notes FDN practitioners can be found via FDNtraining.com/medicine.
