To significantly slow the progression of age-related macular degeneration, a leading cause of blindness, a surprisingly modest diet change is effective. Consuming just two servings of oily fish and 2.7 servings of green leafy vegetables per week reduces the risk of the disease advancing by 41%.

Many cancer cells rely heavily on glucose (the Warburg effect) and cannot efficiently use ketones. A strict ketogenic diet may starve these tumors while nourishing healthy cells. In one case, it led to a 70% reduction in cancer markers in six weeks, far exceeding chemotherapy's expected 30%.
To encourage better choices, emphasize immediate, tangible rewards over long-term, abstract goals. A Stanford study found diners chose more vegetables when labeled with delicious descriptions ("sizzling Szechuan green beans") versus health-focused ones ("nutritious green beans"). This works with the brain's value system, which prioritizes immediate gratification.
Focusing on building muscle is crucial for long-term health, particularly for women entering perimenopause. Muscle helps regulate blood sugar, reduces inflammation, and protects against osteoporosis, dementia, and heart disease, making it a vital health indicator.
Being a "supertaster" has health downsides. Their intense genetic aversion to bitter tastes often leads them to avoid antioxidant-rich foods like leafy greens. This dietary pattern is linked to a higher incidence of colon cancer among supertasters, showing a direct link between taste sensitivity and long-term health outcomes.
Instead of chasing weight loss, focus on foundational health markers like inflammation, blood sugar balance, stress levels, and nutrient deficiencies. When these systems are optimized, sustainable weight loss and body recomposition often occur as a natural side effect.
Starting a meal with vegetables allows their fiber to coat the upper intestine, creating a protective mesh. This slows down the absorption of glucose from starches and sugars consumed later in the meal, dramatically reducing the subsequent blood sugar spike.
A 7-year study of healthy individuals over 85 found minimal genetic differences from their less healthy counterparts. The key to their extreme healthspan appears to be a robust immune system, which is significantly shaped by lifestyle choices, challenging the common narrative about being born with "good genes."
While specific, medically-approved red light therapies show promise for treating conditions like macular degeneration, consumer-grade devices bought online are often unstandardized. They can emit the wrong energy levels, potentially burning the retina and causing irreversible harm.
Chronic illnesses like cancer, heart disease, and Alzheimer's typically develop over two decades before symptoms appear. This long "runway" is a massive, underutilized opportunity to identify high-risk individuals and intervene, yet medicine typically focuses on treatment only after a disease is established.
Nutritional research shows that dietary diversity is a more critical health factor than simply eliminating animal products. People who consume 30 or more different kinds of plants and animals weekly are significantly freer from disease than even those on exclusively vegan or vegetarian diets.
