In Thailand, rapid demographic ageing is closely linked to an increased incidence of non-communicable diseases (NCDs). Effective nutritional management is essential to mitigate NCD risks and delay progression. Given the widespread use of touchscreen devices among older adults, this study focused on developing a nutrition app tailored to enhance knowledge, attitudes, and practices regarding healthy eating among Thai elderly people. Methods: The project consisted of two main phases, namely content preparation and application development. Initial drafts and storyboards were refined through consultations with experts and discussions. The use of healthy menus was approved by a professional chef and nutritionists. The app prototype underwent comprehensive evaluations in terms of content accuracy, design, usability, and acceptability by experts. It was also field tested by elderly volunteers for four weeks. Results: The developed “YoungYou” app features tools such as body mass index assessment, updates on elderly health, and dietary recommendations tailored to Thai elderly individuals based on the nutrition flag system. It includes 60 healthy recipes, 30 cooking tutorials, and an interactive community board. The app allows users to modify and recalibrate the nutritional content of recipes, which can then be saved or shared. Evaluations of the app showed high levels of agreement on its effectiveness across all metrics. The use of rice, vegetables, and meat by 41 elderly volunteers led to increased healthy eating behaviours. Conclusion: The “YoungYou” app has demonstrated potential as a viable tool for promoting healthier eating habits among Thai elderly people, thereby addressing critical public health issues related to ageing and disease prevention.

Introduction: The effects of prolonged consumption of whey protein on health are controversial. This study aimed to determine whether whey protein positively alters health parameters of overweight and obese adults. Methods: Randomised controlled trial was conducted. Fifty-eight participants, aged 30-50 years, were randomly allocated into four groups and supplemented with 50 g protein for eight weeks (group 1: plant-based protein (PBP), group 2: whey protein isolate (WPI) with cocoa powder, group 3: PBP with whey protein concentrate (WPC), and group 4: WPI with milk powder). Body composition and biochemical parameters (kidney and liver functions, inflammation, oxidative stress, and antioxidant capacity) were evaluated at pre-intervention and 8 weeks after intervention. Results: At Week 8, group 3 had lower diastolic blood pressure, waist circumference, visceral fat, and risk of insulin resistance (p<0.05 for all). Group 2 had decreased levels of total cholesterol and low-density lipoprotein cholesterol (p<0.05 for all). A drop in triglyceride was seen in group 4 (p=0.026). Whey protein decreased alanine aminotransferase level (p=0.028), while PBP increased aspartate aminotransferase level (p=0.034). PBP or WPI with milk powder increased blood urea nitrogen level (p>0.05 for all). Interleukin-6 and lactoferrin levels fell in all groups (p<0.05), while hs-CRP increased in the PBP group (p=0.043). Group 2 experienced increased antioxidant capacity. However, levels of oxidative stress markers were significantly decreased in the PBP group and WPI with milk powder group. Conclusion: Whey protein revealed positive effects on anthropometric parameters and biochemical markers of overweight and obese adults. Therefore, proper supplementation of whey protein can potentially promote health.

Introduction: People with lactose intolerance are suggested to consume dietary items containing less lactose, such as goat’s milk. This study aimed to investigate the effects of goat’s milk powder on the health of lactose intolerant middle-aged adults. Methods: A total of 60 subjects were recruited into this randomised controlled trial. They were divided into four groups and received different dietary interventions (goat’s milk, goat’s milk with curcumin, goat’s milk with coffee, lactose-free milk) for five weeks. Health effects were compared between pre- and post-intervention. Anthropometric and biochemical parameters (blood glucose, insulin, lipid profile, C-reactive protein, and lactoferrin) were evaluated. Dietary intake was recorded using a food record. Results: Fifty-one lactose intolerant subjects completed the study. After ingestion of goat’s milk, there were significant reductions in body fat (p=0.033) and a significant increase in the percentage of muscle (p=0.021). Waist circumference (WC) decreased in both the goat’s milk with curcumin and goat’s milk with coffee groups (p<0.05 for all). Unfortunately, high-density lipoprotein cholesterol (HDL-C) dropped after the five-week intervention in the goat’s milk group (p=0.002). Lactoferrin level of the goat’s milk group was higher than other groups at post-intervention (p<0.001). Besides, the goat’s milk with coffee group seemed to consume more carbohydrates after completing the intervention (p=0.034). Conclusion: A five-week intake of goat’s milk reduced the risk of abdominal obesity among middle-aged adults. In addition, it resulted in improved lactoferrin levels.
