GoodQualifiesHIGH confidence
The relationship between genetic predisposition for obesity and body mass index was attenuated by higher diet quality. For example, a 10-U increase in the genetic risk score was associated with a 0.84-U... increase in body mass index for those in the highest tertile of Alternate Healthy Eating Index score compared with a 1.14-U... increase in body mass index for those in the lowest tertile of Alternate Healthy Eating Index score.
