Dr. Joseph Mercola - Take Control of Your Health

Gestational diabetes rates climbed every single year in the U.S. from 2016 through 2024, turning what was once uncommon into a routine metabolic stress test that many pregnancies now fail
The condition reflects years of declining metabolic health before conception, not a sudden problem that starts during pregnancy
Certain racial and ethnic groups face far higher rates, showing that environment, access, and long-standing metabolic strain shape risk well before prenatal care begins
Diets low in usable energy and high in seed oils, along with toxic exposures and inactivity, weaken insulin signaling and set the stage for blood sugar breakdown
Restoring cellular energy, removing seed oils, reducing environmental toxins, optimizing vitamin D through sunlight, and moving daily strengthen glucose control and lower long-term risks for both mother and child

Sleep acts as a nightly repair cycle for your eyes, helping regulate eye pressure, tear balance, immune defense, and retinal cleanup that protect vision over time
Irregular or fragmented sleep disrupts your eyes' internal timing, allowing inflammation, dryness, and visual strain to build even if you eat well and stay active
Circadian rhythm controls when eye tissues repair and defend themselves, and disrupted sleep timing weakens this protection long before obvious eye disease appears
Sleep apnea places extra stress on your eyes by reducing oxygen delivery and disturbing sleep, increasing the risk of optic nerve damage, retinal changes, and surface eye problems that often go unnoticed early
Consistent sleep timing, controlled light exposure at night, deep uninterrupted sleep, morning light, and habits that keep your airway open work together to restore your eyes' natural resilience and long-term health

About 22% of adults have some degree of smell loss, and this sensory change often appears years before serious problems like memory decline, heart disease, or reduced longevity become obvious
Loss of smell is linked to higher risks of depression, social isolation, poor diet quality, and everyday safety hazards such as gas exposure and spoiled food, directly affecting independence and quality of life
Smell dysfunction often shows up early in neurodegenerative disease, which makes changes in your sense of smell an important early signal rather than a harmless part of aging
Simple actions such as regular smell checks, targeted smell training, and improving breathing and sleep patterns support the same brain systems affected when smell declines
Treating smell health like vision or hearing and pushing for routine screening helps identify hidden health risks earlier, when there is still time to take meaningful action

Heart aging begins with weakened communication between your brain and heart, not just clogged arteries or genetics, and preserving that signaling slows structural decline inside heart tissue
Research shows that losing vagus nerve input accelerates cellular aging in the heart, while restoring even a small amount of that signaling preserves coordination, energy production, and pumping efficiency
The vagus nerve actively controls alertness, motivation, recovery, and heart rhythm, meaning daily behaviors directly shape how resilient your heart and nervous system remain over time
Brief, challenging movement that engages large muscle groups sends a powerful wake-up signal from your body to your brain, rapidly increasing focus, drive, and nervous system coordination
Pairing short bouts of hard movement with focused mental work and high-quality sleep strengthens brain-heart signaling, improves recovery, and supports long-term cardiovascular resilience

Gluten-free diets were initially intended for children with medical conditions such as celiac disease, wheat allergy, and non-celiac gluten sensitivity
A review published in Frontiers in Nutrition found that gluten-free diets, when not medically required, can cause nutrient gaps and raise health risks for children
A recent study in The American Journal of Gastroenterology found that young patients exhibited a significant increase in urinary arsenic and other metal levels after only six months on a gluten-free diet
When cooked properly, white rice can be a smarter choice than brown rice because it's easier to digest, contains less arsenic and heavy metals
Instead of cutting out foods that are good for your gut, include healthy carbs, choose stable fats over seed oils, and learn to calm your food fears
