Boosting Muscle Health: The Power of Protein-Enriched food for Seniors
Emerging research reveals that daily consumption of protein-enriched lacto-vegetarian soups can significantly enhance muscle mass and strength in older adults living independently. This dietary approach offers a practical and enjoyable way to combat age-related muscle loss, known as sarcopenia, thereby promoting healthier aging.
In a randomized controlled trial, community-dwelling seniors incorporated these specially formulated soups into their daily meals. The results were promising: participants experienced notable improvements in muscle mass and strength compared to those who did not consume the protein-enriched soups. Sarcopenia, characterized by the gradual decline of muscle tissue with age, can lead to decreased mobility and increased risk of falls. Addressing this condition through accessible dietary modifications is crucial for maintaining independence and quality of life among the elderly.
This study underscores the potential of integrating protein-rich, plant-based options into the diets of older adults. Such nutritional strategies not only support muscle health but also align with sustainable and ethical dietary preferences. By embracing these protein-enriched lacto-vegetarian soups, seniors can enjoy a delicious and effective means to bolster their physical well-being.

Daily Supplementation with Protein-Enriched Lacto-Vegetarian Soups and Muscle Health in Community-Dwelling Older Adults: A Randomized Controlled Trial
Published in The Journal of Nutrition, Health & Aging. By Sheng-Lun Kao et al.
Abstract
Background: Dietary protein adequacy is crucial for muscle health in aging individuals, posing a particular challenge for vegetarian seniors. This randomized controlled trial (RCT) investigates the impacts of protein-enriched lacto-vegetarian soup supplementation on body composition, physical performance and muscle strength functional assessment as well as cardiometabolic and inflammatory biomarkers in older adults.
Methods: We enrolled 100 participants ≥65 years at risk for malnutrition (MNA-SF ≤ 11) and at risk for sarcopenia (SARC-F ≥4 or SARC-CalF ≥11) in this RCT. Participants were randomized assigned to receive a daily protein-enriched lacto-vegetarian soup (24-30 g protein) or usual diet. Primary outcomes of interest including (1) body composition (anthropometric measurements and body composition measured by bioimpedance analysis (BIA)), (2) physical performance (Short Physical Performance Battery, SPPB) and muscle strength (hand grip strength), and (3) functional assessments (including sarcopenia risk scales and nutritional status) as well as secondary outcomes of interests including cardiometabolic and inflammatory biomarkers were assessed at baseline and the 12th week of follow-up.
Results: Data of 97 participants (intervention: n = 48, control: n = 49) were analyzed. Despite no significant changes in body composition were observed in the intervention group, compared to the usual diet, those who received protein-enriched lacto-vegetarian soup supplementation had an improved physical performance including an increase in SPPB score (β = 0.83 [95% CI 0.15-1.51], p = 0.02), a decrease in time to complete the 5 times chair rise test (β = -2.25 [-4.04 to -0.44], p = 0.01). Some functional assessments, including improved sarcopenia risk scale (e.g., SARC-F score [β = -0.68, p = 0.04]) and nutritional status (e.g., MNA-SF score [β = 0.44, p = 0.03]) were also observed.
Conclusions: Daily supplementation with protein-enriched lacto-vegetarian soups enhanced physical performance and functional assessments (such as sarcopenia risk scale and nutritional status) among older adults at risk of malnutrition and sarcopenia. Further study is needed to explore the long-term benefits of protein-enriched lacto-vegetarian soup supplementation for healthy aging.
