Food is the most direct way your body gets the compounds it needs to function—vitamins, minerals, proteins, fats, and thousands of other substances that affect everything from energy levels to immune function. This section covers how different foods and nutrients work in your body, what the research actually shows about their effects, and how to think critically about nutrition claims you encounter. Whether you're curious about a specific food, wondering how a nutrient affects your health, or trying to understand conflicting information you've read, these articles break down the science in plain language.
You'll find explanations of how nutrients are absorbed and used, what happens when you don't get enough of something, and what the evidence does and doesn't support about diet and health outcomes. The articles distinguish between findings from controlled human studies, animal research, and observational data—so you can understand how solid the evidence really is. They also address common questions about food interactions, storage, preparation methods, and whether specific foods live up to their reputation.
