摘要

Background: Being overweight or obese is one of the most harmful risk factors to the health of a population. The cause of obesity is complex and multifactorial, but a primary cause is a nutrient- poor diet. Despite excess intake of calories, diets of obese individuals commonly lack phytonutrients. Phytonutrients such as chlorophyll, carotenoids, and anthocyanins have all been shown to have anti-obesity effects. National data show that populations with the lowest intakes of fruit and vegetable intake also have higher obesity rates. Available data suggest a low fruit and vegetable intake, corresponding to a low phytonutrient intake, is correlated with excess adiposity.Methods: Fifty individuals from Thibodaux, Louisiana were randomly selected to participate in this study. Three 24-hour food recalls were used to calculate phytonutrient content of the diets using the phytonutrient index (PI). A food frequency questionnaire was used to determine intake of specific phytonutrients (carotenoids, anthocyanins, and carotenoids). Body adiposity was measured using body mass index (BMI), waist circumference, and fat percentage. Pearson correlation was used to assess correlations between phytonutrient index and body adiposity measures. Analysis of variance (ANOVA) with post-hoc tests was used to determine differences in PI and phytonutrient intakes among the BMI, waist circumference, and percent body fat groups.Results: Participants who met healthy standards for BMI, waist circumference, and fat percentage all averaged significantly higher PI scores compared to those classified as obese/overweight. A strong inverse relationship was found between PI and BMI (r = -0.753, p = 0.00), waist circumference (r = -0.730, p = 0.00), and body fat percentage (r = -0.701, p = 0.00). Individuals with higher weekly intakes of chlorophyll, carotenoid, and anthocyanin-rich foods had better body composition compared to those who consumed less (p<0.05).Conclusion: Results suggest a strong correlation between higher phytonutrient intake and improved body composition. Overall diet quality seems to make the most difference, but phytonutrients are likely a key reason for those benefits.
