The micronutrient essential for energy production found in whole grains is magnesium. This mineral is vital for the conversion of food into energy, as it plays a key role in essential biochemical reactions, including those involved in ATP synthesis. Adequate magnesium intake supports muscle function, influences metabolism, and helps regulate the nervous system. Whole grains, such as brown rice, oats, and whole wheat bread, are excellent sources of magnesium. Including these foods in one’s diet is crucial for optimal energy levels and overall health.
