Vegetables and plant foods form the foundation of most dietary patterns linked to better health outcomes. This category covers how different vegetables, legumes, whole grains, nuts, and seeds work in your body—what nutrients they contain, how your digestive system processes them, and what the research shows about their effects on everything from heart health to blood sugar control. Whether you're curious about why certain plants are promoted for specific conditions or how to get the most from what you eat, these articles explain the mechanisms behind the claims.

The articles here answer practical questions: What makes some vegetables better sources of particular nutrients than others? How do fiber and plant compounds affect digestion and metabolism? Which plant foods have the strongest evidence behind them for specific health outcomes, and where do questions remain open? You'll find explanations grounded in the type of evidence available—whether from animal studies, human trials, or long-term observational data—so you can understand what's established and what's still being studied.
