To investigate the effects of protein enriched bread and drinking yoghurt, substituting regular products, on the total protein intake and the distribution of protein intake over the day in older adults. A single blind randomised controlled trial. Rehabilitation centre. Older adults (a parts per thousand yen 55 years) admitted to a rehabilitation centre after hospital discharge (n=34). Participants received a high protein diet (protein enriched bread and protein enriched drinking yoghurt; n=17) or a regular diet (regular bread and regular drinking yoghurt; n=17) for three consecutive weeks. Total protein intake and protein intake per meal, measured twice weekly over a three weeks period (six measurements per participant). Compared with controls, patients who received the protein enriched products had a significantly higher protein intake (115.3 g/d vs 72.5 g/d, P < 0.001; 1.6 g/kg/d vs 1.1 g/kg/d, P < 0.001). The intervention group consumed quantities over the recommended level (25-30 g/meal) during each of the three meals (32.5 g, 30.0 g, 34.8 g/meal), where the control group consumed quantities below the recommended level during breakfast (17.7 g) and lunch (18.4 g). The use of protein enriched products, replacing regular products, results in a significant increased daily protein intake in older adults. In addition, the daily consumption of protein enriched products improves protein distribution over the day.
