Abstract:

The importance of fruits and vegetables (FV) in a healthy diet is well accepted; however, the importance of whole grains (WG) is less recognized. This purpose of this trial was to determine the impact of either a FV or a WG intervention on markers of inflammation and gut microbiota composition in overweight or obese individuals that have low intakes of these food groups. Forty-nine overweight or obese subjects with low intake of FV (<2 servings/d) and WG (<1 serving/d) were randomized into three groups: WG (3 servings/d), FV (5 servings/d), and refined grains (RG) (3 servings/d) for 6 weeks. The WG diet resulted in a significant decrease in TNF-α, a proinflammatory cytokine, whereas no significant effects were found on the other diets. There was a significant decrease in LBP on both the WG and FV diets, with no change on the RG diet. A decrease in LBP is a marker of improved gut barrier function. The FV diet had a significant change in IL-6, but no significant change in the other treatments. The FV intervention induced a significant increase in alpha diversity. The WG intervention did not result in any significant differences in microbiota composition. These data support the positive impact that WG and FV intake can have on metabolic health in overweight or obese individuals with normally low intake of WG and FV.
