Higher diet quality attenuates the genetic predisposition for obesity, as measured by body mass index.
If you have a family history of obesity, eating a high-quality diet can help reduce the impact of your genes on your weight. Focus on the quality of your food.
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.
Why this rating
Based on a pooled analysis of 3 cohort studies with 30,904 participants.
