Interventions

  • Avocado — OTHER
    Active foods will provide the equivalent of one medium to large avocado/day in foods such as muffins and pudding, where avocado replaces refined carbohydrate, especially added sugars
  • Control — OTHER
    Control foods will have similar energy contents to active foods, but energy from avocado will be replaced with refined carbohydrate, especially added sugars.

Study Details

The objective of this trial is to assess the effects of replacing foods high in refined carbohydrates, particularly added sugars, with avocado (isocaloric substitution) on biomarkers of inflammation and insulin sensitivity in adults with elevated hs-CRP and central adiposity. Eligible participants will complete two 4-week interventions (1 avocado/d and control) separated by a 2-week washout phase. Participants will complete a total of 7 clinic visits including one screening visit (visit 1, -7 days), one baseline visit (visit 2, day 0), two visits during each 4-week diet condition (visit 3 \& 6 on day 21 and visits 4 \& 7 on day 28), and one visit at the conclusion of the washout phase/start of the second condition (visit 5, day 0).
