Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
-On four different days, ad libitum intake of a soup low or high in salt and low or high in fat (45 min), after a fixed breakfast (45 min).
-Arm 1: low salt and low fat. Arm 2: low salt and high fat. Arm 3: high salt and low fat. Arm 4: high salt and high fat.
-Low salt is 0.04% salt, High salt is 1% salt. Low fat is 0% fat, High fat is 10% fat. Canola oil is used for fat.
-wash out period is one week
Intervention code [1] 290863 0
Behaviour
Comparator / control treatment
cross-over intervention. All participants will consume all fat/salt combinations. The low salt and low fat will be the control.
Control group
Active

Outcomes
Primary outcome [1] 293901 0
food intake (g and kJ) of soup. The soup will be weighed before and after consumption to calculate the quantity of soup consumed.
Timepoint [1] 293901 0
Directly after food intake (15 min) at each of the 4 testing sessions
Secondary outcome [1] 312121 0
Taste sensitivity to fatty acids
Timepoint [1] 312121 0
Assessed by an ascending forced choice test, duration depends on sensitivity (between 5 and 25 minutes). This outcome is assessed before (baseline) and after the four sessions.

Summary
Brief summary
This study aims to investigate the interactions and effects of salt and fat on ad libitum intake. The objective is to quantify the contributions
of different concentrations of salt and fat in food on satiation in humans classified according to fatty acid taste sensitivity. Fifty
participants, aged 18-60 will participate in the study and consume a lunch either low or high in salt and low or high in fat after a fixed breakfast, on four different testing days. Participants will be classified according to fatty acid taste sensitivity, which will be assessed in two different sessions.
