Protein plays a vital role in supporting a healthy metabolism, preserving lean muscle, and promoting feelings of fullness throughout the day. However, many people are unaware that protein needs evolve as we age. Understanding how protein functions in the body—and how to thoughtfully balance different protein sources—is an essential step toward maintaining long-term strength, mobility, and overall health.
What Does Protein Do in the Body?
Protein serves as a foundational building block for nearly every cell in the body, with a particularly important role in muscle tissue. It supports the repair and replacement of cells, contributes to immune system function, and fuels key physiological processes such as metabolism and recovery following physical activity.
Key benefits of adequate protein intake include:
Supports metabolic function
Helps maintain and preserve muscle mass
Promotes satiety and appetite control
Adequate protein intake is not reserved for athletes alone—it is a cornerstone of lifelong health and functional well-being.
Why Protein Needs Increase With Age
As we age, the body becomes less efficient at building and repairing muscle, a process known as age-related muscle loss. Because of this, older adults often require a higher amount of protein per meal compared to younger individuals in order to effectively stimulate muscle protein synthesis.
Additionally, natural declines in muscle mass and strength can impact balance, mobility, and overall independence, increasing the risk of falls or injury. Consistently including sufficient protein at each meal can help support muscle integrity, sustain energy levels, and promote long-term independence as the body changes over time.
Animal-Based vs. Plant-Based Protein Sources
A nutritious diet does not require choosing between animal-based or plant-based proteins—both can contribute valuable nutrients and play an important role in overall health.
Animal-Based Protein Sources:
Eggs
Lean meats (chicken, turkey, lean beef)
Fish and seafood
Dairy products (milk, Greek yogurt, cottage cheese)
Plant-Based Protein Sources:
Beans and lentils
Tofu
Nuts and seeds
Whole grains (such as quinoa and farro)
Each category offers unique benefits, including essential amino acids, iron, zinc, fiber, and healthy fats. Incorporating a variety of protein sources that align with your preferences and lifestyle can help ensure a balanced and nutrient-dense approach to eating.
Final Thoughts for Protein and Muscle Health:
Protein is more than just a macronutrient—it is a powerful tool for supporting metabolism, preserving muscle health, and enhancing long-term vitality. As protein needs may increase with age, establishing habits centered around consistent and balanced protein intake can help you stay strong, energized, and resilient.
Small, intentional choices can have a meaningful impact over time. Adding a handful of nuts to a snack or choosing a higher-protein breakfast are simple strategies that support lasting results. When protein is prioritized with purpose, the body is better equipped to thrive.
