Format: Markdown version of the HTML page (same content, lookups and page chrome left out).

Trustworthy nutrition information: the Dietary Guidelines, food and nutrient databases, how to read a Nutrition Facts label, supplement facts and testing, vitamin stores, and tracking apps. Supplements are not approved by FDA before they are sold, so look for third-party testing, and talk with your doctor or pharmacist before you start one, especially if you take medicine, are pregnant or are managing a health condition. Stores and apps below are commercial.
