As you progress through life, your body undergoes numerous changes, and one area that requires careful attention is your nutrition. As you get older, your body’s nutritional needs evolve, making it essential to adapt your dietary habits to ensure optimal health and well-being. Aging often brings with it a decline in metabolism, reduced muscle mass, changes in hormone levels, and an increased susceptibility to certain health conditions. By understanding and addressing these changes, you can make informed choices about the foods you consume, supporting your body’s changing nutritional needs as you age.
Nutritional Needs in Early Adulthood: 18-30 Years
1. Energy Requirements
During early adulthood, your body requires a sufficient amount of energy to support its growth and daily activities.
