The aim of this study was to investigate the interaction between psychological stress (PS) and drinking status in relation to diet among middle-aged Japanese men and women in a large-scale cross-sectional study. The study population included 5,587 middle-aged Japanese men and 2,718 middle-aged Japanese women who underwent annual health checkups. The subjects were divided into 2 groups (non-drinkers and drinkers) and classified as having low, moderate, or high self-reported PS levels. Energy-adjusted food and nutrient consumption was assessed with a validated food frequency questionnaire. Using a general linear model, food and nutrient consumption was estimated for each self-reported PS level in the 2 groups (non-drinkers and drinkers) and the interactions between self-reported PS levels and drinking status were calculated. In men, pork and beef; squid, octopus, shrimp, and clams; eggs; mushrooms; Japanese-style sweets; ice cream; bread; Chinese noodles; coffee; and soda as foods and protein, animal protein, fat, animal fat, carbohydrate, monounsaturated fatty acid, polyunsaturated fatty acid (PUFA), <i>n</i>-3 PUFA, <i>n</i>-6 PUFA, cholesterol, vitamin D, vitamin B<sub>2</sub>, vitamin B<sub>6</sub>, vitamin B<sub>12</sub>, niacin, pantothenic acid, magnesium, phosphorus, and zinc as nutrients significantly interacted with self-reported PS levels and drinking status (<i>p</i> for interaction <0.05 for all). No specific interactions were found in women. These findings suggest interactions between PS levels and drinking status with consumption of some foods and nutrients, especially macronutrient intake, in men but not in women.
