As we get older, simple activities like getting out of bed, sitting down, or climbing stairs can become more challenging. One of the main reasons for this is a condition called sarcopenia. Sarcopenia is the gradual loss of muscle mass and strength that happens as we age.
This muscle loss can make everyday tasks feel harder and increase the risk of falls and injuries. While staying active and exercising is important, eating the right foods—especially foods high in protein—can also make a big difference in keeping muscles strong.
Our bodies get energy from three main types of nutrients found in food: carbohydrates, fats, and protein. While carbohydrates and fats provide energy, protein does something extra—it gives your body the building blocks it needs to create and repair muscles and other important tissues. These building blocks are called amino acids, and they are essential for muscle health.
Protein can be found in a variety of foods, including meat, fish, dairy products, eggs, and some plant-based options like beans, lentils, and nuts. As we get older, our bodies don’t absorb and use nutrients as well as they did when we were younger. This means older adults need to eat not just enough protein but high-quality protein to keep their muscles strong and healthy.
Unlike fats and carbohydrates, which can be stored in the body for later use, protein is not stored. This means you need to eat protein every day to give your muscles what they need to stay strong. Right now, health guidelines recommend that adults eat about 0.8 grams of protein for every kilogram of body weight each day.
However, research shows that this may not be enough for older adults. Many experts now suggest that people over 65 need around 1.2 grams of protein per kilogram of body weight to maintain muscle health. This is about 50% more than the usual recommendation.
Eating more protein is important, but many older adults face challenges that make it harder to get enough. For example, some may have smaller appetites, dental problems, or trouble preparing meals. Because of this, it’s important not only to eat more protein but to focus on good-quality protein as well.
Good-quality protein is measured by how many essential amino acids it contains and how easily the body can digest and absorb it. One amino acid called leucine is especially important for muscle growth. Foods that are high in leucine, like dairy products, eggs, and lean meats, are particularly helpful for keeping muscles strong.
Recently, there has been growing interest in plant-based proteins for both health and environmental reasons. Pea protein, for example, is becoming popular because it contains enough leucine to support muscle building. While more research is still needed, studies suggest that pea protein could be just as good as animal-based proteins for muscle health in older adults.
A study was done to see how different types of protein affect muscle health in older adults. Thirty-one people aged 60 to 80 participated in the trial. They were given different types of protein through food or supplements, including whey, pea, and collagen protein.
The results were surprising: whey and pea proteins helped build muscle by nearly 10%, while collagen protein had no effect. This shows that plant-based proteins like pea protein can be just as effective as traditional animal proteins for helping older adults maintain muscle strength.
Some people worry that eating too much protein could harm their health, causing problems like cancer, kidney damage, or weaker bones. However, research shows that these fears are mostly unfounded. Eating more high-quality protein, along with regular exercise, can actually help slow muscle loss, improve overall strength, and support better health as you age.
The benefits of eating more protein go beyond just keeping your muscles strong. Protein-rich foods also provide important vitamins, minerals, and even fiber that your body needs.
They also help you feel full longer, which can prevent overeating and help with weight management. To maintain muscle health as you age, aim to eat about 25 to 40 grams of protein at each meal. Some great sources of protein include: Greek yogurt, cottage cheese, eggs, canned fish (like tuna or salmon), lean meats (like chicken or turkey), and nuts and seeds.
You can also add protein-rich snacks throughout the day to make sure you’re meeting your daily needs.
Getting older doesn’t have to mean losing strength. By eating the right amount of good-quality protein every day and staying active, you can help keep your muscles strong and your body healthy. Making protein a regular part of your diet, combined with regular exercise, can slow down muscle loss and help you live a healthier, more active life for many years to come.
