You may want to take a closer look at how much protein you're eating. While protein has always been important for building and repairing muscles, new research suggests that your body may need more of it as you get older to stay strong, active, and independent.
Why Your Protein Needs May Increase
The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. However, many experts now believe that healthy adults over 50 benefit from 1.0 to 1.2 grams of protein per kilogram of body weight each day.
For example, a person who weighs 135 pounds would need about:
RDA: Approximately 49 grams of protein per day
Recommended for many older adults: About 61 to 74 grams per day
Keep in mind that protein needs aren't the same for everyone. Your ideal intake depends on factors such as your age, overall health, physical activity, medical conditions, and personal health goals. Your healthcare provider or a registered dietitian can help determine what's right for you.
What Changes as We Age?
As we grow older, our muscles don't respond to protein as efficiently as they once did.
Scientists call this anabolic resistance. In simple terms, your body needs a stronger signal—more protein and regular strength-building activity—to maintain and rebuild muscle.
Without enough protein, it's easier to lose muscle over time. That loss can make everyday activities more difficult and may increase the risk of falls, frailty, and reduced mobility.
Researchers have also linked anabolic resistance to increased inflammation and reduced insulin sensitivity, both of which may play a role in the development of chronic health conditions.
Why Protein Is Essential After 50
Muscle loss is a normal part of aging, but it doesn't have to happen as quickly as many people think.
Adults begin to lose muscle gradually in their 30s, and the pace often accelerates between ages 40 and 80. Maintaining adequate protein intake can help slow that decline.
Studies have found that older adults who eat more protein tend to preserve more lean muscle mass than those who consume less. In women, higher protein intake has been associated with a significantly lower risk of age-related muscle loss, known as sarcopenia.
Preserving muscle isn't just about strength. It also supports:
Better balance and stability
Easier movement and mobility
Greater independence with daily activities
A healthier metabolism
Improved quality of life as you age
Easy Ways to Eat More Protein Every Day
Adding protein doesn't have to be complicated. Small changes throughout the day can make a meaningful difference.
Try these ideas:
Start breakfast with eggs, Greek yogurt, cottage cheese, or a protein smoothie.
Choose snacks like nuts, seeds, cheese, or roasted edamame instead of chips or sweets.
Include lean protein such as chicken, turkey, fish, or seafood at lunch and dinner.
Add plant-based proteins like beans, lentils, chickpeas, or tofu to soups, salads, and casseroles.
Mix a protein powder into smoothies if you're struggling to meet your daily needs.
Enjoy dairy foods such as milk, skyr, or Greek yogurt for an extra protein boost.
Pair Protein with Strength Training
Protein works best when combined with regular physical activity, especially resistance exercises like lifting weights, using resistance bands, or performing bodyweight exercises.
Together, they help stimulate muscle growth and slow the natural muscle loss that comes with aging.
Even a few strength-training sessions each week can make a noticeable difference in maintaining muscle and staying active.
The Bottom Line
Getting enough protein becomes increasingly important after age 50. While the standard protein recommendation provides a helpful baseline, many healthy older adults may benefit from consuming a little more to support muscle health, maintain mobility, and remain independent for years to come.
If you're unsure how much protein you should be eating, talk with your healthcare provider or a registered dietitian. A personalized plan can help ensure you're getting the nutrition your body needs to age strong and stay active.
