Twenty first century is often called the “age of ageing”. Reduced fertility and rapid dwindling of mortality rates due to biomedical advances, has led to a rise in the ageing population and decline of the youth of the nation. The variable slowing of the organ systems make the elderly more susceptible to many lifestyle and gastrointestinal disorders of which constipation is very predominant. The advent of functional foods like prebiotics shows a promising way ahead. To assess the impact of prebiotics on colonic function of constipated elderly, thirty females above 50 years were chosen for the intervention study. They were assessed on their nutritional status, diet pattern and bowel habits. Prebiotic health mix using dietary sources like whole wheat, oats, saamai. soyabean and artichoke was prepared and packed in hygienic packages. All the samples consumed 10g of the prebiotic mix everyday for a period of 60 days as a drink and its impact assessed. Conclusively, it was found that the formulated drink had profound impact on the colonic function, thereby reducing constipation among the elderly. Positive signs like semisolid stools, increased frequency, lack of strain and less time was taken during defecation.
