5 Ways to Prevent and Reverse Sarcopenia

Omega-3 fats, whey and exercise are just some meaningful ways to fight sarcopenia, or age-related muscle loss, before it strikes during your later years

A form of muscle loss, sarcopenia is a common condition affecting up to 12% of older adults. The progressive loss of skeletal muscle mass and strength is linked to an increased risk of physical disability, poor quality of life and death.[i]

Despite the lack of international consensus on diagnosing sarcopenia, it's characterized by loss of skeletal muscle mass and function in older individuals along with a wide range of patients.[ii],[iii]

You may take meaningful actions to prevent and reverse sarcopenia. Some of its causes are a natural result of aging, but others are preventable through a healthy diet and lifestyle strategies. Quality of nutrition, for instance, may help preserve the ability for skeletal muscle regeneration as you age.[iv] Here are five strategies to help fight this condition naturally.

1. Omega-3s

Omega-3 fatty acids are known to stimulate protein anabolism in animals and may benefit sarcopenia. To test this hypothesis, researchers randomly assigned 16 healthy older adults to receive omega-3 fats or corn oil for eight weeks.[v] Results showed that omega-3s stimulated muscle protein synthesis and may be useful for preventing and treating sarcopenia.

Omega-3 fats are deemed a useful therapeutic agent for the disease due to their anti-inflammatory properties targeting "inflammaging," the age-related chronic low-grade inflammation assumed to contribute to the development of sarcopenia.[vi]

A diet rich in pro-inflammatory foods has, in fact, been correlated positively with the risk of sarcopenia, suggesting an anti-inflammatory diet may be one key to preventing it.[vii]

In addition, omega-3s may also have an anabolic effect on muscle by activating mTOR signaling and reducing insulin resistance. They may complement the effect of exercise or protein supplementation, with researchers urging a further review of the exact dosage, frequency or use of these fats for the said benefit.

2. Whey protein

Protein supplementation is sometimes necessary to maintain skeletal muscle mass, and whey protein is among the best.

In two animal experiments, researchers found that whey protein attenuated induced muscle atrophy by enhancing the net protein content that regulates the synthesis and degradation of muscle protein.[viii] They dubbed the food a "necessary and probable candidate" for developing sarcopenia-fighting functional foods.

Highlighting the combined benefit of therapy and nutritional intervention, separate research found that, combined with omega-3s, polyphenols and electrical muscle stimulation, whey protein increased muscle strength in elderly adults suffering from limited mobility.[ix] Paired with Panax ginseng berry extract, soluble whey protein hydrolysate also ameliorated sarcopenia-related muscular deterioration.[x]

3. Exercise

Exercise leads to sustained benefits to sarcopenia in heart failure cases, helping to attenuate skeletal muscle wasting in this population.[xi] Among sarcopenic men of advanced old age, tai chi and whole body vibration were also found to be effective in improving muscle strength as well as physical performance.[xii]

A 2019 review of 331 articles also revealed that exercise was beneficial for skeletal muscle regeneration, muscle metabolism and motor function in mice with sarcopenia.[xiii] Interventions involved using treadmills, particularly for high-intensity interval training.

4. Miso

Diets marked by high consumption of fish, soybean products, potatoes, most vegetables, mushrooms, seaweeds and fruits, along with low rice intake, was inversely associated with sarcopenia in community-dwelling older Japanese.[xiv]

Miso is a fermented paste that is traditionally added to many Japanese dishes. In a cross-sectional study, habitual miso intake was associated with a low prevalence of sarcopenia in patients with Type 2 diabetes.[xv] Insulin resistance is considered a risk factor for the condition, which is characteristically present in type 2 diabetes sufferers.

5. Vitamin D

Studies on vitamin D supplementation, including a systematic review of 29 studies, offer compelling evidence of increased muscle strength.[xvi] Vitamin D deficiency is a common health problem globally, particularly among older individuals. Vitamin D regulates multiple human functions, including the skeletal muscle, so the fat-soluble vitamin may be crucial to maintain and improve muscle strength and physical performance over time.[xvii]

In a 2012 study, greater visceral fat and lower muscle mass were associated with lower vitamin D3 levels among elderly Korean men.[xviii] Results suggested that screening for deficiency may be appropriate in the elderly with visceral obesity or sarcopenia.
