This study will be a randomized, parallel group comparison of daily avocado consumption vs. habitual diet. The study will be carried out in accordance with the guidelines of the Human Subjects Protection Committee of the University of California, Los Angeles. All subjects will give written informed consent before the study begins.~At screening, informed consent and HIPAA authorization will be reviewed and signed. A medical history will be obtained. Enrollment will be reviewed by the study physician according to inclusion and exclusion criteria. Skin type and response to UVB will be assessed.~At baseline, participants will undergo skin testing. Subjects will consume 1 avocado a day (Hass Avocado) or maintain habitual diet (up to 2 avocados/month) daily for 16 weeks. Skin will be assessed at weeks 0, 8 and 16. Each group will have 20 subjects as calculated by power analysis. Two additional subjects for each group will be recruited for possible dropouts and a total of 22 subjects will be recruited for each group.
This clinical trial aims to assess the effect of providing one avocado per day on skin health in comparison with a control group maintaining their habitual diets. Participants will be randomly assigned to one of two equally sized groups. Both groups will be instructed to continue to follow their habitual diet but the intervention group will receive one avocado per day. Participants will be followed for outcomes for a four-month period.
