I have been extensively testing the Combat Radial Menu (Right Trigger) in regards to using "Quick Items" to consume food items to buff your character prior to entering battles and came to the conclusion that it does not work the majority of the time (worked only roughly 10%-25% of time during my testing).
I made a video where it only worked for Eder exactly 25% of the time (worked on poultry, but failed on meat, beer, and milk):

Note: Workaround (as shown near the end of the video)= using food items from the Character Inventory (Left Trigger) works 100% of the time.
I hope the Devs fix this ASAP on PS4 since this is a pretty severe glitch due to the frequent nature in which it occurs.
