Everything about carbs — types, glycemic index, carb cycling, and the best carb sources for your goals.
The way you cook and serve starchy foods has a meaningful effect on how your body digests them. Cooling cooked starch converts some of it to resistant starch — a form that behaves more like fiber, improves glycemic response, and benefits gut health.
Sweet potatoes are almost universally labeled the healthier choice, but the gap is smaller than most people assume. Both offer real nutritional value, and the best choice depends on what your diet actually needs.
The Mediterranean diet is one of the most extensively studied dietary patterns in the world, yet it is often mischaracterized as low-carbohydrate. In reality, it includes substantial carbohydrates — but the source and quality of those carbs are what set it apart.
Whole grains and refined grains start from the same place — but processing strips away the bran and germ, taking most of the fiber, vitamins, and minerals with it. Here is what the research shows about the practical difference this makes.
Added sugar appears in foods you would not expect: flavored yogurt, salad dressing, bread, pasta sauce, and sports drinks can all contribute substantially to daily sugar intake without obvious sweetness.
Whether to eat carbohydrates before or after training — or both — depends on your goal, workout duration, and intensity. The evidence supports a flexible approach grounded in a few clear principles.
Glycemic index tells you how fast a food raises blood sugar per 50g of carbohydrate. Glycemic load adjusts for how much carbohydrate is actually in a typical serving. In practice, glycemic load is the more useful measure.
Not all fiber sources are equal in nutrition density. This ranked guide covers the top high-fiber foods by grams per serving and per calorie, with context on fiber type and gut health benefits.
The low-carb versus low-fat debate has generated hundreds of studies. The most rigorous recent research suggests that the difference in outcomes is smaller than the debate implies.
The fibermaxxing trend encourages dramatically increasing dietary fiber intake, citing gut health, satiety, and cardiovascular benefits. The science supports the goal but not always the method.
Average fiber intake in the United States sits at around 15 grams per day — roughly half the recommended amount. The gap has measurable consequences for gut health, cardiovascular risk, and blood sugar management.
Resistant starch escapes digestion in the small intestine and reaches the colon intact, where gut bacteria ferment it into compounds that support metabolic and colon health.
