Adherence
Sustained ad libitum consumption of an ultra-processed diet for two weeks does not significantly alter sweet or salty taste detection thresholds or preferences compared to an unprocessed diet.
Eating ultra-processed foods for two weeks does not change your basic ability to taste salt or sugar, nor does it change what you prefer. If you are overeating on these foods, look at factors like eating speed or energy density rather than assuming your taste buds have adapted.
No significant differences were observed in participant salt and sweet detection thresholds or preferences after 2 weeks on ultra-processed or unprocessed diets.
Why this rating
Randomized controlled crossover design with controlled inpatient feeding, but small sample size (N=20) and exploratory nature.
