Finding: Current research evidence on the effect of varying exposure to sweet taste on subsequent sweet taste preferences is equivocal.
Summary: This review looked at the evidence around exposure to sweet tasting foods or drinks and how this influences their acceptance, preference or choice of foods and drinks. Twenty-one studies were included. However, they were diverse in their design, population and outcome measures, and findings were inconsistent. Results were equivocal in population cohort studies. Controlled studies suggest higher sweet taste exposure tends to lead to reduced preferences for sweetness in the shorter term. Very limited effects were found in the longer term.
