Registered dietitian nutritionist Leyla Muedin discusses how exposure to natural daylight may improve metabolic health beyond diet and exercise, highlighting a controlled crossover study of 13 adults aged 65+ with type 2 diabetes published in Cell Metabolism. Participants spent 4.5 days in living spaces lit by either natural light through large windows or artificial light, with identical meals, sleep, activity, and screen time; after a 4-week washout they switched conditions. Natural light was associated with more hours of blood glucose in the normal range, less glucose variability, higher evening melatonin, and improved fat oxidative metabolism, suggesting effects on circadian “body clocks” and coordination between central and peripheral clocks. Muedin recommends getting morning light on the face, reducing sunglasses and high SPF use, dimming lights at night, keeping consistent sleep, and spending more time outdoors; she also notes that architecture can limit sunlight exposure.

Integrative ophthalmologist Dr. Rudrani Banik previews Eye Summit 2026, a free online event May 11–15 featuring four daily expert sessions on dry eye and ocular surface disease, cataract surgery advances (including robotic and AI-assisted planning), gut health links to eye disease, and mind-body approaches for migraine, concussion, and visual snow, with VIP options for recordings and live panels. They discuss photobiomodulation (red/infrared/yellow light) as an FDA-approved treatment for age-related macular degeneration with clinical trials showing safety and potential vision improvement, plus research on low-level red light for pediatric myopia. Banik emphasizes annual dilated eye exams after 40 to detect glaucoma and systemic disease. The episode covers dry eye nutrition (dietary omega-3s; supplements including GLA and omega-7; lutein/zeaxanthin with vitamin D), preservative concerns (BAK), GLP-1 drug associations with NAION, gene therapy delivery via viral vectors, and macular degeneration prevention with lutein/zeaxanthin-rich foods like kale, colored peppers, and egg yolks.

Preventing Injury, Reframing Pain, and Using Physical Therapy to Avoid Unnecessary Surgery: Dr. Tom Walters is a board-certified orthopedic physical therapist, founder of Rehab Science, and author of “Rehab Science: How to Overcome Pain and Heal From Injury,” an illustrated, body-region guide to common orthopedic problems and self-managed therapeutic exercises. Walters emphasizes using PT-style mobility and resistance training preventively to increase tissue capacity, manage load, and avoid overuse injuries, while warning against “no pain, no gain” and excessive volume or weight. He discusses “movement literacy,” hip and glute stabilizers, and how weakness can drive knee and back problems. Dr. Hoffman shares his own hip injury and recovery with targeted strengthening, illustrating that imaging findings often don’t dictate function. Walters explains the biopsychosocial model of pain, graded exposure, the limits of RICE and ultrasound, and roles for manual therapy, taping, TENS, shockwave, acupuncture/dry needling, and PRP. They advocate prehab/rehab around surgery and note PT training and career prospects.

Dietitian Nutritionist Leyla Muedin discusses a Stanford-led randomized controlled trial published in Nature Medicine in which a five-day, calorie-restricted fasting-mimicking diet improved symptoms and inflammatory markers in people with mild to moderate Crohn’s disease. In the three-month study of 97 patients, 65 followed monthly five-day cycles of 700–1100 calories/day with plant-based meals, while 32 continued usual diets; about two-thirds of the fasting-mimicking group reported symptom improvement, with fatigue and headaches but no serious side effects, and fecal calprotectin and other inflammatory molecules decreased. She notes bowel rest and the specific carbohydrate diet as additional approaches. The episode also explains how antibiotics can cause diarrhea by disrupting gut bacteria, lists higher-risk antibiotics, offers supportive steps (hydration, BRAT foods, avoiding irritants), recommends Saccharomyces boulardii taken away from antibiotics, and outlines warning signs requiring medical care, including possible C. difficile.

Indoor Epidemic: Prescribing Nature, Light, Air, and Movement with Dr. John La Puma, internist, chef, and regenerative farmer. His book, "Indoor Epidemic," argues that spending about 93% of life indoors undermines health through poor light timing, air quality, limited movement, and reduced nature exposure. La Puma cites data that outdoor morning light helps set circadian rhythms, while nighttime blue light can impair sleep quality and raise cardiovascular risks, referencing a large UK Biobank study. He discusses indoor pollutants and CO2 buildup affecting inflammation and cognition, recommends strategies like getting daylight early (even just a sky view), using circadian lighting, and taking brief outdoor breaks to reduce myopia risk. He describes measurable benefits of forest bathing and gardening (including immune and mood effects), notes hospital studies linking window views to shorter stays and less pain medication, and reviews his pioneering work in culinary medicine now taught widely in medical schools, emphasizing cooking and growing food as preventive and therapeutic tools.

New Study Links Aged Garlic Extract to Better Cognition: Holistic practitioner Jane Jansen from the Tree of Life Wellness Center in Massachusetts reveals a newly published double-blind, randomized, placebo-controlled trial at the Los Angeles Biomedical Research Institute at Harbor-UCLA involving 72 participants with pre-hypertension or hypertension. Over 12 weeks, one group took 2,400 mg/day of Kyolic Aged Garlic Extract (Reserve formula), and cognitive function was tracked using the Montreal Cognitive Assessment (MoCA). Jansen reports that 92% of the aged garlic extract group had no cognitive impairment after the trial, while the placebo group showed more cognitive decline, with benefits attributed to increased nitric oxide bioavailability, improved endothelial function, better cerebral blood flow, nerve protection/repair, and enhanced brain waste removal. She contrasts this approach with costly Alzheimer’s plaque-busting drugs and discusses prevention strategies, including diet, sleep (glymphatic system), exercise, inflammation control, and circulation-supporting nutrients such as nattokinase.

Nutritionist Leyla Muedin discusses joint inflammation—its symptoms (swelling, pain, redness, warmth, morning stiffness, reduced range of motion) and why it is usually a sign of an underlying condition rather than a disease itself. She reviews common causes including osteoarthritis (cartilage wear and tear), rheumatoid arthritis (autoimmune synovium attack with prolonged morning stiffness and fatigue), gout (uric acid crystals, often in the big toe), psoriatic arthritis, injuries, autoimmune diseases (e.g., lupus, ankylosing spondylitis, Sjogren’s), infections such as septic arthritis requiring urgent care, and surrounding-tissue problems like tendonitis and bursitis. Lifestyle factors that worsen inflammation include excess weight, poor diet (including unaddressed food allergies; avoiding nightshades is suggested), insulin resistance contributing to gout, lack of exercise, smoking, and stress. Management strategies include rest, bracing, ice vs. heat, OTC anti-inflammatories, gentle low-impact exercise, anti-inflammatory foods, weight loss, treating root causes, and supplements such as glucosamine, chondroitin, MSM, bromelain, turmeric, Boswellia, and quercetin.
