Maintaining muscle becomes increasingly important as you get older. Starting around age 30, adults naturally begin to lose muscle mass in a gradual process known as Sarcopenia. Without proper nutrition and longevity boosting exercise, this loss can accelerate with each passing decade. One of the most effective ways to slow this process is by consuming enough high-quality protein. Below are seven of the best protein sources to maintain muscle as you age. These foods provide high-quality protein, are widely available, and can easily fit into a balanced diet.

In general, most active adults benefit from consuming 0.7 to 1 gram of protein per pound of body weight per day, ideally spread across multiple meals. Choosing protein sources rich in essential amino acids—especially leucine—can further support muscle maintenance.

1. Eggs

Eggs are often considered one of the most complete and nutrient-dense protein sources available. They contain all nine essential amino acids, making them a complete protein that your body can easily absorb and use.

One reason eggs are particularly beneficial for maintaining muscle is their high leucine content. Leucine is an amino acid that helps trigger muscle protein synthesis—the process that builds and repairs muscle tissue.

Eggs also provide several important nutrients that support overall health as you age, including vitamin B12, vitamin D, selenium, and choline.

Protein per serving

• About 6 grams of protein per egg

Easy ways to add eggs to your diet

Eggs are incredibly versatile and can be eaten at any time of day. Some easy options include:

• Vegetable omelets for breakfast
• Hard-boiled eggs as a quick snack
• Scrambled eggs with whole-grain toast
• Egg and avocado breakfast bowls

Because eggs are affordable, convenient, and easy to cook, they remain one of the simplest ways to increase your daily protein intake.

2. Greek Yogurt

Greek yogurt is a powerhouse protein source that contains significantly more protein than regular yogurt. During the straining process used to make Greek yogurt, excess liquid is removed, leaving behind a thicker texture and higher protein concentration.

In addition to protein, Greek yogurt contains probiotics that support gut health and digestion. It is also rich in calcium, which helps maintain bone density as you age.

For older adults looking to maintain muscle mass, Greek yogurt is an excellent option because it delivers a substantial amount of protein in a single serving while remaining easy to digest.

Protein per serving

• Approximately 15–20 grams of protein per cup

Simple ways to eat more Greek yogurt

• Add berries, granola, and honey for breakfast
• Blend it into protein smoothies
• Use it as a substitute for sour cream
• Mix with nuts or seeds for a filling snack

Choosing plain Greek yogurt instead of flavored varieties can help avoid added sugars.

3. Chicken Breast

Lean poultry is one of the most common protein staples for anyone trying to build or maintain muscle. Chicken breast is especially popular because it delivers a large amount of protein with minimal fat.

This makes it an efficient way to meet daily protein needs without adding excess calories. Chicken is also rich in B vitamins, including niacin and vitamin B6, which help support metabolism and energy production.

Because it is so versatile, chicken breast can easily be included in lunches, dinners, and meal prep routines.

Protein per serving

• About 26 grams of protein per 3-ounce cooked serving

Healthy preparation ideas

• Grilled chicken salads
• Chicken and vegetable stir-fries
• Protein bowls with rice or quinoa
• Baked chicken with roasted vegetables

Keeping cooked chicken breast on hand can make it easier to add protein to meals throughout the week.

4. Salmon

Fish provides high-quality protein along with several nutrients that support healthy aging. Salmon is particularly beneficial because it contains omega-3 fatty acids, which may help reduce inflammation and support heart and brain health.

Omega-3 fats may also play a role in maintaining muscle strength and function as people age. Combined with its high protein content, this makes salmon one of the most nutrient-dense protein sources available.

Another advantage is that salmon is relatively easy to cook and pairs well with many different foods.

Protein per serving

• About 22 grams of protein per 3-ounce serving

Easy ways to include salmon in meals

• Baked salmon with roasted vegetables
• Salmon salads for lunch
• Salmon rice bowls with avocado
• Grilled salmon with quinoa

Eating fish several times per week can help provide both protein and heart-healthy fats.

5. Cottage Cheese

Cottage cheese has long been popular among athletes and fitness enthusiasts because of its high protein content and slow digestion rate.

Much of the protein in cottage cheese comes from casein, a slow-digesting protein that releases amino acids gradually. This makes it particularly useful for preventing muscle breakdown over longer periods, such as overnight.

Cottage cheese is also low in calories while still being filling, making it a helpful addition to balanced meals or snacks.

Protein per serving

• Around 24 grams of protein per cup

Ways to eat cottage cheese

• Pair with fruit like pineapple or berries
• Add nuts or seeds for extra nutrition
• Spread it on whole-grain toast
• Use it in protein pancakes or smoothies

Because of its high protein content and convenience, cottage cheese is an excellent option for boosting daily protein intake.

6. Lentils

Not all high-quality protein comes from animal products. Lentils are one of the best plant-based protein sources available, making them an excellent choice for vegetarians or anyone trying to incorporate more plant foods into their diet.

In addition to protein, lentils are packed with fiber, iron, potassium, and antioxidants. The fiber content also supports digestive health and helps keep you full longer.

Plant-based proteins like lentils can play an important role in a balanced diet, especially when combined with other protein-rich foods.

Protein per serving

• About 18 grams of protein per cooked cup

Easy lentil meal ideas

• Lentil soups and stews
• Lentil and vegetable curries
• Protein-packed grain bowls
• Lentil salads with olive oil and herbs

Because they are affordable and shelf-stable, lentils are a great pantry staple for healthy meals.

7. Whey Protein

While whole foods should form the foundation of most diets, protein supplements can be helpful when it’s difficult to meet daily protein needs through food alone.

One of the most popular options is whey protein, which is derived from milk during the cheese-making process. Whey protein is quickly absorbed and contains high levels of essential amino acids, including leucine.

This rapid absorption makes whey protein especially useful after workouts, when muscles need nutrients to recover and rebuild.

Protein per serving

• Typically 20–25 grams per scoop

Simple ways to use whey protein

• Blend into smoothies with fruit and milk
• Mix into oatmeal or yogurt
• Make protein pancakes
• Drink as a quick post-workout shake

For busy individuals, whey protein can be a convenient and effective way to support muscle maintenance.

FAQ

What protein is best for seniors?

High-quality proteins that contain all essential amino acids are typically best. Examples include eggs, fish, poultry, dairy products, and whey protein. Plant-based options like lentils, beans, and tofu can also support muscle health when included regularly.

How much protein should a 60-year-old eat daily?

Many experts recommend that older adults consume 0.7 to 1 gram of protein per pound of body weight per day, depending on activity level and health goals.

Can you build muscle after 50 with enough protein?

Yes. With adequate protein intake and regular strength training, adults can build and maintain muscle well into their 50s, 60s, and beyond.

Is plant protein as good as animal protein for aging muscles?

Plant proteins can support muscle health, though they sometimes contain lower levels of certain amino acids. Eating a variety of plant protein sources can help ensure you receive a complete amino acid profile.

What happens if older adults don’t eat enough protein?

Low protein intake can accelerate muscle loss, increase fatigue, and reduce strength. Over time, this may contribute to mobility issues and reduced independence.

Should you eat protein at every meal?

Yes. Spreading protein intake across meals can help stimulate muscle protein synthesis throughout the day and support muscle maintenance.

Is protein powder safe for older adults?

For most healthy adults, protein powder can be a safe and convenient way to increase protein intake. It can be especially useful when appetite decreases or when meeting protein needs through food alone becomes difficult.
