Effect of Increased Whole Apple Consumption, Apple Extract and Freeze-dried Apple Products on Biomarkers of Cardiovascular Disease Risk: a Randomised Intervention in Participants at Increased Risk of Cardiovascular Disease
Abstract
This study will examine if health benefits of consuming nutrient-rich apples, an apple extract and freeze dried apple product will be similar. 50 volunteers at increased risk of heart disease will consume either a low apple diet (\<1 portion/d), 2 high or low polyphenol apples/day, an apple extract, or freeze dried apple granule product for 4 weeks (ten participants per group, randomly assigned). Apart from the extract group, all volunteers will consume a placebo. All volunteers will follow a low apple diet (\<1 apple per day) other than what has been provided by the research team. Volunteers will complete food diaries at the start and end of the study and a number of questionnaires. Blood and urine samples collected at 0 and 4 weeks
Conditions: Cardiovascular Disease.
Primary outcome: Between group change in oxidised-LDL.
Enrollment: 55 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 55 participants or records.
