Background
Increasing coffee intake was inversely associated with risk of type 2 diabetes in Western countries. However, in China where coffee consumption and diabetes population has been growing fast in recent years, studies on the impact of coffee intakes on the onset of type 2 diabetes are lacking. This study attempts to determine the associatio...

Background
Previous studies suggest a positive effect of tea intake on cognition. Additional micronutrients that may moderate this association was not previously examined.
Objective
To examine the association between tea consumption and cognition and explore the interaction between tea consumption and iron intake.

... Similarly, coffee consumption which was considered a western lifestyle, has significantly gained popularity in China, a country with long history of drinking green tea. The demand for coffee has also grown rapidly in recent years 16 . Statistical reports show that Chinese population consumed around 4.8 million 60-kg bags of coffee, as coffee production volume in China amounted to around 1.8 million bags in the same period. ...
Primary dysmenorrhea (PD) is a common global health concern. However, limited studies explored the association between soft drinks intake and PD among female undergraduates in China. To determine the association between soft drinks (carbonated soft drinks, etc.) as well coffee intake and the incidence/severity of PD among female undergraduates in China. We performed a cross-sectional study among 1809 female undergraduates in China from September 29, 2020 to October 22, 2020. The demographic information and menstrual information of the participants were collected by a self-administrated questionnaire. Chi-square test, ANOVA test, and logistic regression test were used to investigate the association between soft drinks intake and the incidence/severity of PD. We also conducted stratification analysis among different locations (rural or urban). The prevalence of PD was 47.1% (n = 852). There were 221 (25.9%) participants suffered from severe pain. In the participants with PD, the OR of carbonated soft drinks intake was 1.244 (95% CI 1.010–1.533). Among the participants with PD from rural areas, the OR of carbonated soft drinks intake was 1.402 (95% CI 1.045–1.881), compared with the non-carbonated soft drink group. In the participants with moderate and severe PD, the OR of coffee intake was 0.451 (95% CI 0.228–0.892), compared with the non-coffee-drinking group. There was a significant association between carbonated soft drinks intake frequency and the severity of PD (P < 0.05). Our study showed that carbonated soft drinks intake is a risk factor for PD, especially in participants from rural areas. Coffee intake is a protective factor for the severity of PD. Periodical awareness programs about adverse effects of excessive soft drink consumption should be introduced to reduce the prevalence and exacerbation of PD. Coffee intake might be helpful to relieve the severity of PD.

Conclusion
Our study showed that carbonated soft drinks intake is a risk factor for PD, especially in participants from rural areas. Coffee intake is a protective factor for the severity of PD. Periodical awareness programs about adverse effects of excessive soft drink consumption should be introduced to reduce the prevalence and exacerbation of PD. Coffee intake might be helpful to relieve the severity of PD.
We aimed to investigate the association between coffee drinking and total caffeine intakes with the chance of prediabetes (Pre-DM) regression and progression over 9-years of follow-up.
This cohort study included 334 Pre-DM individuals (mean age of 49.4 ± 12.8 years and 51.5% men) who participated in the third phase of the Tehran Lipid and Glucose Study (2006–2008). A validated food frequency questionnaire at baseline assessed habitual coffee consumption. All measurements were done at baseline and all subsequent examinations with 3-year follow-up intervals. The odds ratios (OR) and 95% confidence intervals (CIs) of Pre-DM regression to normal glycemia or progression to type 2 diabetes (T2D) in coffee drinkers/non-drinkers were estimated using multinomial logistic regression analysis.
During the study follow-up 39.8% of the study participants were progressed to T2D and 39.8% returned to normal glycemia. Coffee consumption nearly doubled the chance of returning to normal (OR = 2.26, 95% CI = 1.03–4.97). Total caffeine intake was not related to Pre-DM progression and regression. Compared to non-drinkers, coffee drinkers had significantly lower 2-hour serum glucose concentrations over time (152, 95% CI = 144–159 vs. 162, 95% CI = 155–169 mg/dL, P = 0.05).
Habitual coffee drinking may increase the chance of returning to normal glycemia in Pre-DM subjects.
