Korean Cohort Data on the Traditional Diet and Metabolic Syndrome Complicate the 'Hansik Is Healthy' Story

In the Korean Genome and Epidemiology Study, a diet built mostly around white rice with little dietary variety tracked with higher central obesity and abnormal fasting glucose, not lower risk. Large Korean cohorts show that grain diversity, vegetable variety, and fish intake, not 'tradition' as a label, carry the protective signal, while sodium from soy sauce, doenjang, kimchi, and salted fish remains an unresolved structural cost of the pattern.

PCOS Nutrition: What the Evidence Actually Supports for Insulin-Resistant Women

Polycystic ovary syndrome affects roughly 10% of women of reproductive age. The condition is metabolically driven for the majority of patients — and the dietary interventions with strong evidence are narrower and more specific than popular advice suggests.

Carbohydrate Quality Beats Carbohydrate Quantity

Two diets with identical carbohydrate gram counts can produce dramatically different metabolic outcomes. The variable that matters is not how many carbs you eat, but which ones — and what comes with them.

Glucose Variability After Meals: The Metabolic Signal That Average Blood Sugar Hides

HbA1c and fasting glucose describe averages. The shape of the curve after a meal — how high it rises, how fast it falls, how often it spikes — predicts cardiovascular and metabolic outcomes that the averages miss entirely.

Glycemic Index Is the Wrong Compass: Use Glycemic Load

Watermelon has a glycemic index of 72, which is high. A standard serving of watermelon has a glycemic load of 4, which is very low. The two numbers tell different stories, and the one that actually matters for blood sugar response is the second one.

The Fiber Gap: Why the Most Boring Nutrient Is Also the Most Underconsumed

Protein trends, fat debates, and sugar panic dominate nutrition conversation. Fiber, the one macronutrient with consistent evidence for nearly every health outcome that matters, barely gets mentioned. The intake data explains why that matters.

High-Protein Diets and Kidney Health: What the Evidence Actually Says

The claim that high protein intake damages healthy kidneys has persisted for decades. The clinical evidence tells a more nuanced story than either side of the debate acknowledges.

Complete vs Incomplete Proteins: A Distinction That Barely Matters

The idea that plant proteins must be carefully combined at every meal to form 'complete' proteins has persisted for decades. The biochemistry of amino acid pooling tells a different story.

The Protein Myth: Why 0.8g/kg Is Outdated for Most People

The RDA for protein was designed to prevent deficiency, not to optimize health. New dietary guidelines and decades of research suggest most adults need substantially more.
