How Excess Iodine Is Undermining Thyroid Health and What to Do About It - Discussion Between Dr. Alan Christianson, Ashley Armstrong, and Dr. Mercola

Story at-a-glance Chronic disease is at an all-time high — Modern lifestyle shifts have fueled skyrocketing rates of diabetes, heart disease, obesity and autoimmune disorders Vegetable oils have replaced natural fats — Marketed as a healthier alternative, seed oils high in linoleic acid have contributed to inflammation, mitochondrial dysfunction and metabolic disease Endocrine-disrupting chemicals (EDCs) are everywhere — Found in plastics, pesticides and personal care products, EDCs interfere with hormone function, impacting fertility, thyroid health and cancer risk Lifestyle factors are driving mitochondrial decline — Inactivity, poor diet and lack of sunlight exposure have disrupted natural metabolic processes, which led to energy deficits and chronic fatigue Traditional lifestyles offer a blueprint for better health — Whole foods, natural movement and circadian alignment support mitochondrial function and cellular repair, and reverse modern health declines

Story at-a-glance Approximately 10% to 15% of Americans suffer from irritable bowel syndrome (IBS), a functional gastrointestinal disorder characterized by unpredictable symptoms that disrupt daily life Recent research reveals that psychological stress trains your body to misidentify safe foods as threats. This rewires your immune and nervous systems to produce pain responses in the gut Stress increases mast cell activity in the gut, which leads to nerve hypersensitivity and immune system changes that trigger IBS symptoms like bloating, pain, and altered digestion When stress becomes chronic, hormones like cortisol and CRF impair digestion, damage the gut lining, and throw off your microbial balance, worsening IBS symptoms Managing IBS involves comprehensive lifestyle strategies, including stress reduction techniques like mindfulness, exercise, improving sleep, and supporting gut health through diet and potential supplements

Story at-a-glance A recent study found that free-form dancing matches or exceeds the intensity of jogging or cycling, making it a viable alternative for cardiovascular exercise Unlike structured workouts, free-form dance requires no gym membership or equipment, making it a fun and sustainable way for people of all ages to stay active Dancing with music significantly increases heart rate and calorie burn, improving cardiovascular fitness while making exercise feel less strenuous and more enjoyable Free-form dance engages multiple muscle groups while stimulating cognitive functions like coordination, balance, and reaction time, reducing the risk of falls and mental decline Research highlights that dancing fosters social connections, enhances mood, and provides a structured form of self-expression, making it a powerful tool for lifelong health

Story at-a-glance A nearly 80-year Scottish study found older gardeners performed better on memory and thinking tests than non-gardeners, even after adjusting for education, income and exercise Gardening challenges multiple brain regions through planning, memory use, problem-solving and decision-making, providing a more complete mental workout than simple exercise The sensory experience of gardening — touching soil, smelling plants, seeing colors an spending time outdoors — stimulates your brain while reducing stress hormones and improving mood Starting a garden requires no experience — even growing windowsill herbs or container plants provides brain benefits and helps build "cognitive reserve" against age-related decline Beyond brain health, gardening offers social connection through community gardens and clubs, which further reduces dementia risk and improves overall well-being

Story at-a-glance Consuming just four servings of ultraprocessed foods daily increases depression risk by 10% in adults over 70, according to a six-year Australian study of 11,192 older adults Ultraprocessed foods trigger inflammation, disrupt the gut-brain axis and cause oxidative stress — all known contributors to depression and cognitive decline in older populations Linoleic acid (LA) in vegetable oils damages cellular mitochondria, reducing energy production and increasing inflammation; keep daily intake below 5 grams, ideally under 2 grams Dietary changes that support mental health include eliminating vegetable oils, focusing on whole foods and choosing filtered water over sweetened drinks Many people underestimate their processed food consumption; tracking food intake for five days helps reveal hidden sources of inflammatory ingredients affecting brain function

Story at-a-glance Versatile therapeutic benefits — Dimethyl sulfoxide (DMSO) is a potent compound known for treating a wide range of conditions, including chronic pain, stroke recovery, tissue damage, autoimmune disorders, various skin conditions, and complex infections Unique role in cancer care — DMSO’s distinctive properties enable it to support the body in combating cancer while safeguarding healthy cells from the harmful effects of chemotherapy and radiation Enhanced chemotherapy delivery — When paired with chemotherapy, DMSO improves the drug’s ability to penetrate cancer cells that are typically inaccessible, significantly boosting treatment effectiveness Lower doses, reduced toxicity — By enhancing the potency of chemotherapy, DMSO allows for the use of lower doses, substantially reducing the toxic side effects associated with conventional cancer treatments Synergistic potential — DMSO demonstrates promising results when combined with various pharmaceutical agents, amplifying their cancer-fighting capabilities

Story at-a-glance Glycerol, a common additive in sugar-free slushie drinks, can trigger severe medical symptoms in young children, including unconsciousness, seizures and dangerously low blood sugar A study across the U.K. and Ireland found that nearly all affected children became sick within an hour of consuming slushies, with no prior health issues or underlying medical conditions Symptoms mirrored rare metabolic disorders, confusing emergency responders and delaying proper treatment, despite the cause being an ingredient found in a popular children's beverage Glycerol exposure caused measurable metabolic disruption, including low blood sugar, acid buildup in the blood, low potassium and high triglyceride levels unrelated to fat intake Avoiding slush ice drinks completely eliminated the problem in nearly all of the children, making removal of this one product a powerful step for parents looking to protect their child’s health

Story at-a-glance Many common medications contain hidden gluten and soy in their "inactive" ingredients, which trigger reactions in sensitive individuals A study found 44.4% of pain relievers contained gluten and 14% of NSAIDs contained soy-based additives, with poor labeling making identification difficult Solid oral medications most commonly contain gluten, while liquids and suppositories more frequently contain soy derivatives Exposure to these hidden allergens causes serious health consequences ranging from digestive issues to permanent damage in those with sensitivities Focus on leading a healthy lifestyle to reduce your reliance on medications that contain hidden allergens; this includes optimizing sun exposure, avoiding processed foods, eating enough healthy carbs and prioritizing daily movement

Story at-a-glance Research suggests "normal" vitamin B12 levels are insufficient for optimal brain health, especially in older adults, despite being above the standard medical threshold Vitamin B12 helps your nerves work well by protecting them with a special coating, allowing brain messages to travel quickly and clearly A study of healthy older adults showed that lower B12 levels, even within the "normal" range, were linked to slower thinking and brain signals Signs of low B12 include brain fog, memory issues, tingling in hands and feet, and mood swings; these symptoms often develop gradually Rich sources of B12 include grass fed meat, eggs and dairy; supplementation is often necessary for vegans, older adults or those taking certain medications like metformin

Story at-a-glance Essential oils like ginger, lavender and frankincense have natural anti-inflammatory properties that reduce joint pain and stiffness when used consistently Daily essential oil use through massage, aromatherapy or baths supports your arthritis care routine and helps improve quality of life over time Regular use of essential oils like ginger, peppermint and eucalyptus targets inflammation, improves blood flow and supports joint healing A four-week essential oil plan helps you gradually introduce safe, effective habits for pain relief — starting with patch tests and ending with custom essential oil blends Powerful oil combinations like ginger-turmeric-frankincense or lavender-clary sage-marjoram provide extra relief, particularly when matched to your specific pain type
