Several epidemiological studies conducted in Western countries have investigated the correlation between soup intake and obesity-related parameters, such as body mass index (BMI). We investigated the correlation between soup intake and obesity-related parameters by a cross-sectional study on Japanese adults. As results, the frequency of soup intake is inversely associated to obesity-related parameters, such as BMI (p&lt;0.05), waist circumference (p&lt;0.05), waist/hip ratio (p&lt;0.01), and plasma leptin concentrations (p&lt;0.05). These results suggest that soup intake inversely correlated to obesity-related parameters in Japanese adults.<br/>   Next, we aimed to determine the association between soup intake and obesity-related parameters by conducting a systematic review and meta-analysis. The observational studies on the association of soup consumption to obesity-related parameters were screened by database search. From 1873 identified articles, 7 cross-sectional studies were included in the review. All studies indicated a significant inverse correlation between soup consumption and obesity. The meta-analysis of the studies of which outcome is odds ratio for obesity revealed that soup consumption is significantly related to lower odds ratio of obesity in combined data (n=45292, OR: 0.85, 95% CI: 0.79-0.91, p&lt;0.0001), suggesting that soup consumption was inversely correlated with a risk of obesity.
