The need for older adults to increase their protein intake has been noted increasingly more regularly by experts. The composition of our bodies change as we age, resulting in:
- A loss of protein tissue from 30% as a young adult to 20% by the age of 70
- A reduction in organ tissue, blood components, immune bodies, total body potassium and water found in the body
- A decrease in skeletal muscle to approximately 27% of total body weight from 45% as a young adult
- Protein tissue accounts for 30% of whole-body protein turnover, but that rate declines to 20% or less by age 70. 1
Protein plays a vital role in helping older adults stay active and functional. Recent research suggests that older adults who consume more protein are less likely to lose “functioning,” the ability to dress, get out of bed, walk up a flight of stairs, etc.
In a 2018 study 2 that followed more than 2,900 seniors over 23 years, researchers found that those who ate the most protein were 30% less likely to become functionally impaired than those who ate the least amount.
New research in the Journal of Nutrition, Health & Aging reveals that older people in the United States do not consume enough protein. 3
What are the protein requirements for people over 65?
The Recommended Dietary Allowance for protein intake (0.8g protein/kg body weight/day) may not be adequate to support optimal health for older adults. 4
Physiologic changes and reduced lean body mass during aging lead to decreases in total body protein (functional muscle mass) and contribute to increased frailty, impaired wound healing, and decreased immune function.
Some experts suggest protein intake of 0.54 0.9 g protein per pound of body weight per day is better for older adults as studies have shown them to be less responsive to low doses of amino acid intake. This is much higher than the RDA for people below 65. 5
How can protein bars benefit seniors?
- A common problem for older adults is muscle wastage, leading to Sarcopenia (the loss of skeletal muscle mass and strength as a result of aging) 6. Increasing protein intake helps to increase muscle mass and prevents muscle wastage.
- Protein bars are a convenient snack that requires no preparation, cooking, weighing, or measuring.
- The protein RDA for those over 65 is much higher than for younger adults. With between 8g – 30g in each protein bar, they can go a long way towards meeting this increased goal.
- Protein can help to boost the immune system, which is crucial for seniors, especially those recovering from illness.
- As we age, our appetite tends to decrease. Meal replacement bars can provide additional vitamins and minerals, along with protein, carbs, and fats for those who struggle to eat a full meal.
