Don’t Let Your Muscles Fade Away: Understand How the Need for Protein With Age Changes, Says Irish Nutrition Expert Dr. Clare Corish

A new study reveals that many people, especially older adults, are unaware of this crucial fact, according to Dr. Clare Corish, an associate professor in clinical nutrition and dietetics at UCD.

Protein: The Building Block of Our Bodies
Protein is a vital nutrient for building and repairing tissues throughout the body. It’s like the tiny building blocks that make up our muscles, bones, skin, and even hair. We constantly need a steady supply of protein to keep our bodies functioning properly.
Calculating Your Protein Needs
The European Food Safety Authority recommends a daily intake of 0.83 grams of protein per kilogram of body weight. For a 70kg adult, that translates to roughly 58 grams of protein each day.
However, this is just a baseline. Certain groups require more protein. Children and teenagers, for example, need more protein relative to their body weight compared to adults. Athletes and people looking to build muscle mass may also benefit from increased protein intake.

Why Our Protein Needs Increase With Age
As we enter our 40s, we begin to lose muscle mass at a rate of 1% per year. This can worsen to 2-3% muscle strength loss annually. This muscle loss is linked to a condition called sarcopenia, which can lead to decreased mobility and an increased risk of falls and fractures.
The reason our protein needs increase with age is twofold. First, our bodies become less efficient at absorbing protein from food. Second, we simply need more protein to counteract the ongoing muscle loss.
