Abstract Title: 

Improving fruit and vegetable intake attenuates the genetic association with long-term weight gain.

Abstract: 

BACKGROUND: Whether changes in fruit and vegetable intake can modify the effect of genetic susceptibility to obesity on long-term changes in BMI and body weight are uncertain.OBJECTIVE: We analyzed the interactions of changes in total and specific fruit and vegetable intake with genetic susceptibility to obesity in relation to changes in BMI and body weight.METHODS: We calculated a genetic risk score on the basis of 77 BMI-associated loci to determine the genetic susceptibility to obesity, and examined the interactions of changes in total and specific fruit and vegetable intake with the genetic risk score on changes in BMI and body weight within five 4-y intervals over 20 y of follow-up in 8943 women from the Nurses' Health Study (NHS) and 5308 men from the Health Professionals Follow-Up Study (HPFS).RESULTS: In the combined cohorts, repeated 4-y BMI change per 10-risk allele increment was 0.09 kg/m2 among participants with the greatest decrease in total fruit and vegetable intake and -0.02 among those with the greatest increase in intake (P-interaction
