Food is the fuel on which your body runs. Without enough food, you don’t have enough energy. Nutrients are chemical substances your body uses to build, maintain, and
repair tissues. They also empower cells to send messages back and forth to conduct essential chemical reactions, such as the ones that make it possible for you to breathe, see, move, hear, eliminate waste, smell, think, taste and do everything else natural to a living body.
Food provides two distinct groups of nutrients: macronutrients and micronutrient. The difference between the two groups is the amount you need each day. The daily requirements for macronutrients generally are more than one gram. The daily requirements for micronutrients are much smaller. For example, the Recommended Dietary Allowance (RDA) for vitamin C is measured in milligrams
(1⁄1,000 of a gram), while the RDAs for vitamin D, vitamin B12, and folate are even smaller and are measured in micrograms (1⁄1,000,000 of a gram)(Webb 38).
