What is sarcopenia-osteoporosis?
Sarcopenia-osteoporosis (also known as osteosarcopenia) is defined as the coexistence of sarcopenia and osteoporosis. The global prevalence is 18.5%, and the prevalence of sarcopenia-osteoporosis in China is as high as 19.8%. Elderly, female, frail and malnutrition are high-risk factors. For patients with primary osteoporosis, it is necessary to pay attention to the adverse effects of reduced muscle mass or impaired muscle strength on bone tissue structure and function. While managing osteoporosis, it is necessary to increase muscle mass and strength, ultimately increasing bone density and reducing the risk of falls and fractures.
Supplement nutrients for osteoporosis and sarcopenia
Nutritional intervention is an effective method for preventing and treating sarcopenia. Through scientifically sound dietary adjustments and supplementation, older adults can significantly improve muscle health and slow the progression of sarcopenia. The following are some supplement nutrients for osteoporosis and sarcopenia.
Protein: The Foundation of Muscle Health
Protein is a basic nutrient for muscle growth and repair. As we age, the body’s protein synthesis capacity decreases. Elderly people often cannot get enough protein from their daily diet, which accelerates muscle loss. Therefore, the elderly need to pay special attention to protein intake.
Leucine: The magic ingredient that promotes muscle synthesis
Leucine, a branched-chain amino acid, acts as a catalyst for muscle synthesis. With aging, the body’s ability to metabolize leucine weakens, leading to decreased muscle synthesis. Studies have shown that leucine supplementation can help activate muscle protein synthesis, particularly in the elderly, and can significantly improve muscle mass and strength.
Supplementation amount: Taking more than 3 grams of leucine per day can help promote muscle protein synthesis and increase muscle mass and strength.
Food sources: Whey protein: Whey protein, rich in leucine, is the best choice for elderly people to supplement leucine. Whey protein is not only rich in leucine, but also easily absorbed by the body, which can quickly provide nutrition to muscles.
Other sources: eggs, milk, tofu and other soy products, etc.
Vitamin D: Helps maintain muscle health
Vitamin D is not only essential for bone health but also enhances muscle function. Studies have shown that vitamin D can promote calcium absorption, improve muscle strength, and enhance exercise capacity in older adults. Elderly individuals often experience vitamin D deficiency due to lack of sunlight exposure, requiring supplementation through diet or supplementation.
Older adults should consume 800 to 1,000 international units (IU) of vitamin D daily to help promote calcium absorption and maintain muscle health.
Food sources: Deep-sea fish (such as salmon and tuna), egg yolks, dairy products, etc. are all foods rich in vitamin D.
n-3 polyunsaturated fatty acids: dual effects of anti-inflammatory and muscle building
n-3 polyunsaturated fatty acids, particularly DHA and EPA from fish oil, have significant benefits for muscle health in older adults. Studies have shown that n-3 fatty acids can reduce inflammation and promote muscle protein synthesis, thereby helping to prevent muscle loss. Daily supplementation with appropriate amounts of n-3 fatty acids can help increase muscle mass and improve physical function.
Consuming at least 2 grams of n-3 fatty acids per day can help increase muscle mass and improve walking speed.
Food sources: Deep-sea fish (such as salmon, herring, etc.), flaxseed oil, perilla oil, etc.
Dietary fiber and antioxidants: promote digestion and slow down aging
Dietary fiber and antioxidants also play a positive role in maintaining muscle health. Dietary fiber regulates intestinal health and improves the balance of the gut microbiome, thereby protecting muscle mass. Antioxidants such as vitamins C and E and beta-carotene help reduce oxidative stress in the body and slow the aging process.
Sources of dietary fiber: Foods rich in dietary fiber, such as fresh fruits, vegetables, whole grains, and potatoes, help promote intestinal health.
Supplementing with probiotics and prebiotics: Improving gut health
Gut health is closely related to muscle health. Supplementing with probiotics and prebiotics can improve the balance of intestinal microorganisms, promote protein absorption and utilization, and thus help maintain muscle mass.
Sources of probiotics: Yogurt, fermented soy products, etc. are rich in probiotics.
Sources of prebiotics: Inulin, oligofructose, etc. help promote the growth of probiotics and improve intestinal health.
Reasonable eating pattern
To ensure that the elderly get adequate nutrition and avoid sarcopenia, a reasonable diet is crucial. The elderly’s diet should be varied to ensure that each meal provides sufficient protein, dietary fiber and other essential nutrients.
Conclusion
For patients with osteoporosis and sarcopenia, dietary supplements and exercise types should be appropriately selected based on their actual health status, including physical strength. Dietary supplements and appropriate exercise can improve the structure and function of bone and muscle tissue.
