Physical deterioration and loss of muscle mass are the body’s main natural response to aging. Studies show that, during their lifetime, the average man is estimated to lose 30% of their muscle mass as the body grows older.1

Muscle loss and sarcopenia 

Age-related muscle loss, also called sarcopenia, will contribute to greater weakness and reduced mobility, as well as increase the risk of falls and fractures.[2] The American Society for Bone and Mineral Research found that people with sarcopenia are more prone to fractures from a fall. In addition, the prevalence of sarcopenia was more common in those with sub-optimal dietary protein intake and with low physical activity.3

Preventing aging with a healthy diet

Maintaining a healthy diet is important to support healthy aging and reduce physical deterioration. Together with regular exercise, a nutrient-dense diet may reduce inflammation and oxidative stress and help to provide the body with the best outlook for physical and cognitive health down the track.4

Certain foods and nutrients are of particular benefit for good health, energy production, and muscle growth. In particular, consuming high-quality protein can provide the body with a steady source of energy and help preserve muscle mass.5 

Why is protein important for physical deterioration?

Sufficient protein intake can be essential to maintain muscle mass and strength, both of which are vital for supporting mobility and preventing injuries. Protein requirements increase as you age due to a decline in skeletal muscle. In addition, this decline may be worsened by poor diet or inactivity.6

Approximately 10-25% of older adults consume less protein than the Recommended Dietary Allowance (RDA) and 5-9% of older adults consume less than the Estimated Average Requirement (EAR) of 0.66g/kg/day.7

It has been suggested that protein helps reduce bone density loss by increasing calcium absorption in the body, and therefore, minimizing the risk of osteoporosis.8 

How to increase your daily protein intake

It may be difficult for some people to receive their daily protein intake from food sources only. Clean Lean Protein by Nuzest is an ideal addition to the diets of older adults looking to supplement their protein intake and to help ensure their body’s nutritional needs are met. 

One 25 gram serving of Clean Lean Protein provides 18-21 grams of highly available protein, and is easy for the body to digest and utilize. It contains all nine essential amino acids, which play an important role in maintaining muscle mass. Particularly, leucine has been suggested to increase protein synthesis, and therefore, help to minimize symptoms of age-related physical deterioration.9

Prevention can be key when it comes to decreasing the risk of chronic disease and physical deterioration. Fortunately, functional capacity and independence later in life can be potentially achieved by maintaining a healthy lifestyle and meeting daily nutritional requirements.
