I’ve been strength training for most of my adult life, and it’s really important for me to maintain strength as I get older. I recently started reading a lot about protein as an important macronutrient when it comes to muscle maintenance, so I decided to share some of my findings here this week.
Protein is one of the most vital macronutrients for maintaining health and promoting longevity. It plays a crucial role in almost every biological process in the human body, from muscle repair and growth to enzyme function, immune system support, and hormone regulation. As we age, the importance of protein intake becomes even more apparent, contributing to a better quality of life and increased vitality.
One of protein’s primary functions is to repair and build tissues, especially muscles. As we grow older, we experience a natural decline in muscle mass, known as sarcopenia. This loss of muscle can lead to weakness, decreased mobility, and an increased risk of falls and fractures. Eating enough protein helps to combat this muscle loss, keeping the body stronger and more resilient. Additionally, when paired with regular resistance exercise, protein can enhance muscle maintenance and even stimulate growth.
Beyond muscle health, protein supports immune function, helping the body produce antibodies that defend against infections and illnesses. As we age, our immune systems can weaken, making it crucial to maintain a diet rich in high-quality protein sources. This can include lean meats, fish, dairy products, legumes, and plant-based proteins like beans and lentils.
Protein also plays a significant role in weight management. A diet rich in protein can promote satiety, helping to control appetite and reduce the tendency to overeat. Maintaining a healthy weight is a key factor in longevity, as it reduces the risk of chronic diseases like heart disease, diabetes, and hypertension.
Finally, protein is essential for maintaining skin, hair, and nail health. It helps regenerate cells and keep these tissues strong and health.
How Much Protein Should You Get Each Day
The recommended daily protein intake for adults varies based on factors like age, activity level, and overall health. However, general guidelines provide a good starting point:
For adult females – 46 grams
For adult males – 56 grams
Keep in mind these are general guidelines. Another way to look at it would be to aim for around 7 g of protein per 20 pounds of body weight.
Most recommendations suggest aiming for around 15–25% of your total daily calories from protein is optimal.
Incorporating adequate amounts of protein into your diet is essential for living a long, strong and healthy life. By supporting muscle health, immune function, and overall body composition, protein is a powerful partner at any age and even more so as we move into our later years.
