The coffee industry has grown very fast ever since international coffee brands were launched in the 1990's. Recently, consumers have begun to focus on coffee produced ethically. This phenomenon is due to ethical-consumption consciousness, which consists of three factors, emotional value, social value and function value. Most studies on this topic have focused on consumers who purchase fair-trade coffee. Thus, this study is novel in its focus on baristas who sell fairtrade coffee in their shops as well as differences from former studies. The three factors of ethical-consumption consciousness of baristas affected the sale of fair-trade coffee, except for the function value. Therefore, the sale of fair-trade coffee could be influenced by ethical-consumption consciousness of baristas. This study shows that education of baristas can promote the sale of fair-trade coffee. However, there are limitations as it only researched coffee brands ranked in the top 5, so further studies will be required in the future.

This study evaluated the nutrient intake with increasing coffee consumption for 403 adults aged over 30 years in Korea. The 403 subjects were national health screening examinees, who visited Sahmyook Seoul Hospital's Comprehensive Check-up Center between 2017.11.01 and 2018.12.18. The subjects were asked to answer questionnaires covering a 24-hour recall fluid and dietary intake before the health examination. The research ethics council of Sahmyook University (2-7001793-AB-N-012019036HR) approved this study. Coffee consumption exceeding two servings daily was more likely in males, in those aged between 30 and 40 years, and in the smoking, drinking, non-exercise, non-breakfast groups compared to each counterpart. The correlation between the coffee consumption frequency and current nutrient density showed negative correlations in most micronutrients. The mean nutrient density decreased gradually with increasing coffee consumption (<1 serving daily, ${\leq}1{\sim}2$ servings daily, >2 servings daily) in the ANOVA analysis. Therefore, the progressive adverse health effects of excessive coffee consumption needs to be researched further, and a daily total caffeine limit should be suggested in education of the nation levels.

BACKGROUND/OBJECTIVES: Habitual coffee consumption was inversely associated with type 2 diabetes (T2D) and hyperglycemia in observational studies, but the causality of the association remains uncertain. This study tested a causal association of genetically predicted coffee consumption with T2D using the Mendelian randomization (MR) method. SUBJECTS/METHODS: We used five single-nucleotide polymorphisms (SNPs) as instrumental variables (IVs) associated with habitual coffee consumption in a previous genome-wide association study among Koreans. We analyzed the associations between IVs and T2D, fasting blood glucose (FBG), 2h-postprandial glucose (2h-PG), and glycated haemoglobin (HbA1C) levels. The MR results were further evaluated by standard sensitivity tests for possible pleiotropism. RESULTS: MR analysis revealed that increased genetically predicted coffee consumption was associated with a reduced prevalence of T2D; ORs per one-unit increment of log-transformed cup per day of coffee consumption ranged from 0.75 (0.62-0.90) for the weighted mode-based method to 0.79 (0.62-0.99) for Wald ratio estimator. We also used the inverse-variance-weighted method, weighted median-based method, MR-Egger method, and MR-PRESSO method. Similarly, genetically predicted coffee consumption was inversely associated with FBG and 2h-PG levels but not with HbA1c. Sensitivity measures gave similar results without evidence of pleiotropy. CONCLUSIONS: A genetic predisposition to habitual coffee consumption was inversely associated with T2D prevalence and lower levels of FBG and 2h-PG profiles. Our study warrants further exploration.

When purchasing products or services, consumers tend to purchase multiple value attributes through the acquisition of a product rather than physical characteristics. This study empirically analyzed the relations between consumption value, brand attitude, and purchase intention of customers purchasing fair-trade coffee, by dividing consumption values that would have significant effects on consumers' actual purchase behavior into five levels. Among the consumption value factors of customers purchasing fair-trade coffee, the functional value, social value, emotional value, and rare value all had significant effects on brand attitude and purchase intention while the influence of situational value on brand attitude and purchase intention was not verified. These finding are partially concordant with those of preceding studies, and the consumption value of consumers purchasing fair-trade coffee has positive effects on purchase behavior; therefore, it would be necessary for companies selling fair-trade products to understand consumers' specific values. Moreover, analysis of the influence of brand attitude on purchase intention of customers purchasing fair-trade coffee revealed that purchase intention increased when brand attitude was higher. These finding indicate that it is necessary to identify measures to increase purchase intention by targeting consumer groups with high brand attitude with intensive promotions.

The purpose of this study was to assess nutrient intake and dietary quality in female college students according to their coffee consumption. The survey was conducted through questionnaires and 3-day dietary records with 353 students. The subjects were divided into three groups: students who didn't consume coffee (non-coffee group, N=119), students who consumed <250 ml coffee (light-coffee group, N=140), and students who consumed ${\geq}$250 ml coffee (moderate-coffee group, N=94). There were no significant differences in age, weight, height, and BMI among the three groups. The mean daily energy intake was 1800.8 kcal in the non-coffee group, 1724.9 kcal in the light-coffee group, and 1729.7 kcal in the moderate-coffee group. The moderate-coffee group consumed a significantly higher amount of alcohol than the light-coffee group (p<0.05). The average intakes of dietary fiber, vitamin A, ${\beta}$-carotene, and folate in the non-coffee group were significantly higher than those in the light-coffee and moderate-coffee groups. Indexes of Nutritional Quality (INQ) for vitamin A, niacin, and vitamin B6 were significantly higher in the non-coffee group than in the light-coffee group. Also the non-coffee group consumed a significantly higher amount of vegetables compared to the light-coffee group. There was no significant difference in the Dietary Diversity Scores (DDS) among the three groups. These results suggest that coffee consumption affects food and nutrient intake in female college students.
