Food groups and risk of weight gain

Finding: Intake of wholegrains, fruits, nuts, legumes and fish were inversely association with overweight/obesity while positive associations were found for refined grains, red meat and sugar sweetened beverages (SSB).

Summary:

This meta-analysis summarised the evidence of a prospective association between intake of 12 different food groups and risk of general overweight/obesity (OO), abdominal obesity (AO) and weight gain (WG). Evidence quality was rated using the NutrGrade tool. In the dose response meta-analysis inverse associations (relative risk) were found for intake of whole grain (OO RR 0.92), fruit (OO RR 0.93; WG RR 0.91), nut (AO RR 0.42), legume (OO RR 0.88) and fish (AO RR 0.83). Positive associations were found for refined grains (OO RR 1.05), red meat (AO RR 1.10; WG RR 1.14) and SSB (OO RR 1.05). The findings were judged to be very low to low quality evidence and to improve this better-designed observational studies, inclusion of intervention trials and use of novel statistical methods were recommended.
