简要总结
This randomised controlled trial aims to assess the effects of three different types of dietary advice for reducing free sugar intakes, on intakes of free sugar, in a sample of the UK population.
详细描述
The primary objective of this randomised control trial is to assess the effects of three different types of dietary advice, for reducing total energy intakes (TEI) of free sugar. A total of 150 participants (age 18-65years) consuming diets >5% total energy intake from dietary free sugars will be recruited from across the Dorset region. All participants will be asked to reduce their free sugar intake to <5% TEI, and to aid with this, they will be encouraged to reduce their intakes of specific foods identified as high in free sugars. Participants will also be advised to replace these foods with other foods dependent on their taste. Participants will be randomized to replace high sugar foods with: 1) foods that are low in sugars, but high in sweet taste; 2) foods that are low in sugars, but high in other tastes; and 3) foods that are low in taste. The primary outcome will be changes in free sugar consumption from baseline to endpoint at week 12. Secondary outcomes include change in: BMI; dietary profiles; sweetness preference; sweetness liking; food choices; low calorie sweetener intakes and adherence levels at week 12.

研究组 & 干预措施
Dietary Advice: Sweet Taste
Participants will be asked to reduce their free sugar intakes to less than 5% TEI. To aid with this, they will be asked to reduce their intakes of foods and drinks high in free sugars, and replace these with foods low in sugars, that remain high in sweet taste, eg. fruit, low-calorie sweetened foods and drinks. The intervention will be provided to participants in written form, in an opaque sealed envelope.
干预措施: Dietary Advice (Behavioral)
Dietary Advice: Taste
Participants will be asked to reduce their free sugar intakes to less than 5% TEI. To aid with this, they will be asked to reduce their intakes of foods and drinks high in free sugars, and replace these with foods low in sugars, that remain high in taste, eg. nuts, foods and drinks flavoured with herbs and spices. The intervention will be provided to participants in written form, in an opaque sealed envelope.
干预措施: Dietary Advice (Behavioral)
Dietary Advice: No taste
Participants will be asked to reduce their free sugar intakes to less than 5% TEI. To aid with this, they will be asked to reduce their intakes of foods and drinks high in free sugars, and replace these with foods low in sugars, that are low in taste, eg. foods and drinks that are plain-flavoured, wholegrains. The intervention will be provided to participants in written form, in an opaque sealed envelope.
