Contribution of beverages to the intake of polyphenols and antioxidant capacity in obese women from rural Mexico

D Hervert-Hernandez & I Goni, Contribution of beverages to the intake of polyphenols and antioxidant capacity in obese women from rural Mexico, Public Health Nutrition,2011.

The aim of this paper was to study beverage consumption among obese women from rural communities in Mexico and to estimate daily polyphenol intake and dietary antioxidant capacity from beverages. A cross-sectional study was used to analyse the beverage intake of 139 premenopausal obese women estimated through repeated 24h food recalls. Total polyphenol content and antioxidant capacity were determined in 18 beverages representing 71% of total beverage consumption, in order to estimate the intake of polyphenols and the dietary antioxidant capacity from beverages. The contribution of beverages to dietary energy was 1369kj/d. Soft drinks were consumed the most, followed by coffee and fresh fruit beverages. Polyphenol intake and dietary antioxidant capacity from beverages was 180.9 mg/person per d and >1000 μmol Trolox equivalents/person per d, respectively. The items that contributed most to this intake were coffee, roselle drink, peach and guava juices and infusions. These authors conclude, ‘There is an urgent need to reduce the consumption of sugar-sweetened beverages among obese women from rural Mexico . Low sugar beverages rich in polyphenols and antioxidants may be healthier op
