Flavonoids link to less weight gain
Eating fruit and vegetables that contain high levels of flavonoids, such as apples, pears, and berries, may be associated with less weight gain.
Dietary flavonoids are natural compounds found in fruits and vegetables. These have been linked to weight loss, but most studies have looked at a particular flavonoid found in green tea, and have mostly been limited to small samples.
So a team of researchers examined the association between the dietary intake of seven flavonoid subclasses and weight change in a large study of 124,086 men and women based across the US over 24 years.
They tracked participants who were part of three prospective cohort studies: the Health Professionals Follow Up Study, Nurses' Health Study, and Nurses' Health Study II, the BMJ reported.
Participants self-reported their weight, lifestyle habits, and any recently diagnosed diseases via questionnaire every two years, between 1986 and 2011. In addition, they self-reported their diet every four years. Findings revealed that increased consumption of flavonoid subclasses was associated with less weight gain.
Blueberries and strawberries were the main source of anthocyanins, and flavan-3-ols and their polymers were mainly derived from tea and apples. Orange juice and oranges were the main sources of flavanone and flavones, and tea and onions were the main sources of flavonols.
