Getting enough protein is a challenge for older patients

Aged Care Iron Nutrition SPONSORED


As appetite decreases with ageing, it is important for older Australians to eat nutrient-rich foods to make every bite count.

Up to 1.2g protein per kg has been recommended to counteract age-related muscle loss in adults 65 years and older.1,2

Older adults have higher protein needs compared to younger adults.3 Yet average protein intake is inconsistent with emerging evidence on muscle health which suggests optimal health depends on maintaining muscle mass in older Australians.4

Skeletal muscle mass is reduced by up to 50% in older adults5, and a sedentary lifestyle and sub-optimal diet can exacerbate this age-related muscle loss.2

Consuming adequate protein, in combination with regular resistance exercise, helps maintain muscle function important for sustaining an active and independent lifestyle in older people.

Two to three protein-rich meals a day

The anabolic response to protein ingestion is also reduced with ageing6 which means a greater amount of dietary protein is required to build and maintain muscle mass in older adults.

While the total amount of protein is important, protein intake is best consumed across two to three meals a day, with each meal providing 25-30g of protein.1,7

Spreading protein intake across the day helps maintain a positive protein balance and improve protein synthesis7,8, optimising the benefits achieved from regular physical activity.

How can GPs help patients?

Protein-rich meals for muscle health is a patient education fact sheet prepared by Meat & Livestock Australia (MLA) that explains the different types of foods and amounts needed to achieve 25g protein in a meal.  

The simple guide avoids the need to calculate the amount of protein which is often confused with the actual weight of food.

For example, 150g of meat (raw weight) provides around 25g of protein. For meals prepared with a smaller portion of meat or protein alternatives, select two foods from column two or three foods from column three, to provide 25g of protein.

Protein-rich meal ideas are presented below and show three different ways to achieve a meal that provides 25g of protein.

Nutrient-rich protein foods

To achieve a nutritionally adequate diet, older adults need to eat a variety of foods in amounts recommended in the Australian Dietary Guidelines.9

As appetite decreases with ageing, it is important for older Australians to eat nutrient-rich foods to make every bite count.

Many protein-rich foods are also important sources of other essential nutrients:

  • Three serves of dairy foods a day provides calcium, important for bone health
  • Red meat, such as lean beef and lamb, three to four times a week provides iron and zinc, important for immune function
  • Fish twice a week provides omega-3, important for heart health
  • Legumes, such as lentils, beans or hummus, provide fibre and prebiotics, important for gut health

Easy meal ideas

Meals that are easier to chew and swallow are suggested for older adults. Examples include soups, casseroles and meals made with minced meat (i.e. bolognaise sauce, chilli con carne and meat balls).These convenient options can also be frozen and thawed for easy and readily available meals.
