Nutrition — the essentials

Variety, wholesomeness, and moderation are the three fundamental rules for a healthy diet—the key to running success. Following these rules will ensure that you eat a balanced diet that provides you with plenty of energy. In general, foods consumed in their natural state provide good nutritional value and contain few unhealthy ingredients. If you follow the first two rules, the third one usually follows—although allowing yourself a small treat now and then won’t affect your performance, and can even be a good motivational tool.

 

VITAMINS AND MINERALS

A varied diet that encompasses the six key food groups opposite should provide most of the vitamins and minerals you need. The most important ones are listed in this table.
