Effects of promoting eating foods containing bitter vegetables on nutritional status in the elderly

Background: Non-communicable diseases pose a considerable risk for the elderly population. This study aimed to investigate the impact of incorporating bitter vegetables into the diets of elderly individuals on their nutritional status. The study involved regular consumption of northern foods, such as Malidmai (Peka), salae, neem (neem), bitter gourd, and cassia, at least once a day for three months. Materials and methods: A randomized clinical trial recruited eighty individuals aged 60 years and above. One group was allowed to eat ad libitum, while the other group followed a recommended menu that emphasized bitter flavors. The study assessed dietary intake, body composition, and blood biochemical parameters. Results: The findings revealed a significant reduction in energy, saturated fat, and cholesterol intake, with the bitter group experiencing a statistically significant decrease in sugar consumption. The bitter group also demonstrated a considerable reduction in anthropometric and metabolic parameters when compared to the control group and baseline measures. These results indicate the potential benefits of bitter substances in managing or preventing obesity and type 2 diabetes in the elderly. Conclusion: Encouraging the elderly to consume at least one bitter meal per day for 12 weeks resulted in a reduction in weight gain, adipose tissue, sugar levels, and LDL-C. The study highlights the importance of incorporating bitter vegetables into the diets of elderly individuals for better nutritional status and health outcomes.
