Are You Really Getting Enough Protein for Healthy Aging?

Author_Cliff-Harvey healthy aging

Protein supplements are seen by many as the sole domain of pumped-up bodybuilders and strength athletes. And while protein is extremely important to build and repair muscle, it’s equally important for general health, especially as we get older. Have you ever asked yourself if you are really getting enough protein for healthy aging?

What’s Protein?

Protein is made up of amino acids. These little guys are the building blocks of nearly every cell and tissue in the human body, including muscles, organs, and many chemical messengers necessary for us to think, feel, and perform at our very best.

Here are a few key benefits of protein supplementation as we age:

  • Helps us retain muscle

    As we age, we typically lose muscle (and gain fat!). Increased protein helps us to retain muscle, and lose more fat.1-4

  • Improved cardiovascular (heart and circulation) health

    Increased protein can reduce blood pressure, improve blood lipids, and reduce fat stores.5, 6

  • Improved bone health

    As we get older, our bones can become more brittle and less dense. Higher protein diets have been shown to reduce this bone loss and improve the strength of our bones as we age.2, 7, 8

  • Improved immunity and resistance to infections

    Protein and one of the amino acids that we derive from protein, glutamine, help the body to retain immunity and reduce infection.9

How much protein do I really need as I age?

The recommended daily allowance for protein is 0.8 g per kilogram of bodyweight per day. This isn’t considered enough to provide a full range of health benefits as we age though. It’s been suggested that at least 1 g of protein per kg of bodyweight is necessary to reduce muscle and bone loss as we age.

The following tips have been suggested for healthy aging:

  • Consume 25-30 grams of protein at breakfast, lunch, and dinner. (E.g. 150 g of chicken, fish, or meat, or 1-1 ½ servings of Clean Lean Protein)10
  • Have a protein drink or smoothie with at least 20 g of protein (1 serving of Clean Lean Protein) after exercise.
  • Use protein smoothies (E.g. Clean Lean Protein, berries, kale or spinach, nut butter, milk or substitute of your choice) as an easy, convenient, protein-rich meal.
  • Adequate protein intake is essential for people of all ages to ensure that we are meeting our nutritional needs and adequately fueling our bodies. This is especially true as we age, so make sure to each a protein-rich diet for your health today and tomorrow.
