BACKGROUND: Beans are a candidate food to increase satiety due to their protein and dietary fiber content. Beef is a common animal protein that can increase satiety due to its protein content, which is higher than beans, but does not contain dietary fiber. Dietary guidance encourages higher intake of plant-based protein foods and warrants satiety studies that compare plant and animal protein foods, which could particularly benefit the rapidly growing population segment of older adults. OBJECTIVE: To compare effects of two bean varieties and beef consumed within a breakfast tortilla on satiety, food intake, and 24-h energy intake in older adults. METHODS: Older adults (n = 35, age 72.4 ± 6.66 y, BMI 25.1 ± 3.25 kg/m RESULTS: Fullness and satisfaction were significantly increased, while hunger, desire to eat, and prospective food consumption were significantly decreased, following consumption of the black bean, red kidney bean and extra-lean ground beef test meals. Appetite sensation AUCs, ad libitum pizza intake, and 24-h energy intake did not significantly differ between the test meals. CONCLUSIONS: These results demonstrate that beans improve satiety to an extent that is not significantly different from beef in older adults thereby supporting a role for beans as a nutrient-dense source of protein and dietary fiber as part of a satisfying meal for older adults. This trial was registered at clinicaltrials.gov as NCT05499819.
