Malnutrition or its risk is common among older people. To maintain adequate nutrition, increased meal frequency is important. In addition to main meals, regular consumption of nutrient- and energy-dense snacks is recommended. The study examines the post-meal responses to dairy- and berry-based snacks tailored for older people. The plasma concentrations of glucose, insulin and free fatty acids are measured during three hours after snack consumption. In addition, subjective satiety responses and heart rate variability are recorded.

Change in postprandial satiety scores assessed by using visual analogy scales
Visual analogue scales (VAS) are used to assess satiety and other related subjective sensations (fullness, hunger, desire to eat, alertness) within 3 hrs after meal. Each VAS consists of a 100-mm horizontal line anchored with verbal descriptions at each end expressing the weakest (0 mm) or strongest (100 mm) statement of sensation. Results are scores between 0 and 100.
Time frame: 3 hrs
Heart rate variability
Electrocardiography monitoring for assessment of several variables of heart rate variability
Time frame: 3 hrs
