Abstract
BACKGROUND During Ramadan fasting, postprandial hyperglycemia is commonly observed after iftar (break of fast at sunset) meal. D-allulose is a rare sugar and is reported to have several health benefits, including the suppression of increase in postprandial glucose levels. This study investigates whether D-allulose (a C-3 epimer of D-fructose) improves the postprandial glucose in patients with type 2 diabetes mellitus (T2DM) during Ramadan. METHODS This was a pilot, prospective single-arm study design that was conducted for 10 consecutive days; 5 days of control and 5 days of consumption. The primary outcome was postprandial peak glucose levels. During the consumption period, 8.5 g of D-allulose was consumed by the participants before iftar meal. Postprandial glucose was measured using a continuous glucose monitoring system. RESULTS A total of 12 participants completed the study. Significant lower (p < 0.01) postprandial glucose values and the glucose incremental area under the curve (iAUC) were observed from 0 to 180 min during the consumption period compared to the control period. The consumption period demonstrated significantly higher percentages of time in which glucose values were found in the target range (p = 0.0032), and when the glucose levels above the target range were reduced (p = 0.0015). CONCLUSIONS The supplementation with D-allulose has the potential to improve postprandial hyperglycemia in patients with T2DM after iftar during Ramadan. Further studies are needed to confirm these findings. Trial registration ClinicalTrials.gov NCT05071950. Retrospectively registered, 8 October 2021.

Abstract
AIM To test the association of alcohol consumption with total and cause-specific mortality risk. DESIGN Prospective observational multi-centre population-based study. SETTING Sixteen cohorts (15 from Europe) in the MOnica Risk, Genetics, Archiving and Monograph (MORGAM) Project. PARTICIPANTS A total of 142 960 individuals (mean age 50 ± 13 years, 53.9% men). MEASUREMENTS Average alcohol intake by food frequency questionnaire, total and cause-specific mortality. FINDINGS In comparison with life-time abstainers, consumption of alcohol less than 10 g/day was associated with an average 11% [95% confidence interval (CI) = 7-14%] reduction in the risk of total mortality, while intake > 20 g/day was associated with a 13% (95% CI = 7-20%) increase in the risk of total mortality. Comparable findings were observed for cardiovascular (CV) deaths. With regard to cancer, drinking up to 10 g/day was not associated with either mortality risk reduction or increase, while alcohol intake > 20 g/day was associated with a 22% (95% CI = 10-35%) increased risk of mortality. The association of alcohol with fatal outcomes was similar in men and women, differed somewhat between countries and was more apparent in individuals preferring wine, suggesting that benefits may not be due to ethanol but other ingredients. Mediation analysis showed that high-density lipoprotein cholesterol explained 2.9 and 18.7% of the association between low alcohol intake and total as well as CV mortality, respectively. CONCLUSIONS In comparison with life-time abstainers, consuming less than one drink per day (nadir at 5 g/day) was associated with a reduced risk of total, cardiovascular and other causes mortality, except cancer. Intake of more than two drinks per day was associated with an increased risk of total, cardiovascular and especially cancer mortality.

Abstract
BACKGROUND AND AIMS Given the growing concerns that international trade agreements may increase the supply of health-harming commodities, including alcohol, this study aimed to investigate the changes in alcoholic beverage preference and consumption after Taiwan's accession to the World Trade Organization (WTO). DESIGN A before-and-after comparison analysis using data from two waves (1993-1996 and 2005-2008) of the Nutrition and Health Survey in Taiwan (NAHSIT), before and after Taiwan's accession to the WTO in 2002. SETTING Taiwan. PARTICIPANTS A total of 5031 and 2910 participants aged 19 years or older in NAHSIT 1993-1996 and 2005-2008, respectively. MEASUREMENTS Alcohol measures included beverage-specific preference, mean daily ethanol consumption, and heavy drinking. Logistic regression was used to estimate the prevalence rate ratios and rate differences of beverage preferences between the two waves and the risk ratios of heavy drinking associated with different beverage preferences. FINDINGS A reduced prevalence rate of drinkers who preferred rice spirits (prevalence rate ratio [PRR] = 0.47; 95% confidence interval [CI] = 0.24, 0.91) and Asian wine (PRR = 0.11; 95% CI = 0.04, 0.29) was found in contrast to an increase in the preference for fruit wine (PRR = 2.90; 95% CI = 1.75, 4.79); the preference for Asian spirits showed a non-significant increase (PRR = 1.63; 95% CI = 0.88, 3.02). Similarly, the mean daily ethanol consumption decreased for Asian wine and increased for Asian spirits. Compared with beer, an increased risk of heavy drinking was associated with rice spirits (adjusted risk ratio [aRR] = 3.30; 95% CI = 1.68, 6.47) and Asian spirits (aRR = 2.64; 95% CI = 1.38, 5.01). CONCLUSIONS After Taiwan became a member of the World Trade Organization and abolished its alcohol monopoly in 2002, the pattern of alcoholic beverage preference changed markedly, including a decrease in drinkers who preferred rice spirits and Asian wine (53% and 89% decrease, respectively) and an increase in drinkers who preferred fruit wine and Asian spirits (2.9-fold and 1.6-fold increase, respectively).

Abstract
As the prevalence of type 1 and type 2 diabetes increases and population-level patterns of alcohol and illicit drug use evolve, clinicians will continue to encounter people with diabetes whose substance use is affecting health outcomes. Substance use contributes substantially to the population-level prevalence of cardiovascular events, cerebrovascular events, cancers, mental health conditions, road trauma, and domestic violence. Alcohol and drug use also have a measurable effect on diabetes incidence and the development of both acute and chronic diabetes-related complications. In this Review, we examine the effect of alcohol and illicit drug use on people with type 1 or type 2 diabetes. We describe evidence for substance use as a risk factor for new-onset diabetes, prevalence of use in people with diabetes, evidence linking substance use with diabetes-related health outcomes, and evidence on the management of these co-occurring conditions.

Abstract
BACKGROUND Studies of the role of alcohol use in diabetes risk have rarely included lifetime alcohol use measures, including the frequency of heavy occasions, or evaluated risks among Black or Hispanic respondents in US samples. METHODS Data from the 2014 to 2015 National Alcohol Survey of the U.S. population were used to estimate diabetes risk from drinking patterns at the time of onset in Cox proportional hazards models in a retrospective cohort design. Models for the population, males and females, and for White, Black, and Hispanic respondents of both genders were estimated using 2 versions of drinking pattern groupings at each age. RESULTS While a number of significant results were found with the first version of the drinking measures, we focus on those confirmed with measures from responses strictly prior to the age of risk estimation. Compared to the lifetime abstainer group, the "drinking at least weekly with less than monthly 5+" group had a significantly lower hazard ratio (HR) for the total sample (HR = 0.64) and among Whites (HR = 0.42). Significantly reduced risks were found in the same models for those who drank 5+ at least monthly but not weekly. No significantly elevated risks were found for either current or prior heavy occasion drinking. CONCLUSIONS These results are consistent with some prior studies in finding reduced risks for regular light-to-moderate drinkers, but not consistent with findings from other studies showing increased risk from heavy occasion drinking, particularly among women. New and larger studies with well-defined drinking pattern measures are needed, particularly for U.S. Blacks and Hispanics, to address varying results in this literature.

Abstract
BACKGROUND Previous studies report conflicting results of a dose-dependent association between alcohol consumption and incidence of chronic kidney disease. Only a few studies have assessed the clinical impact of > 45-65 g/day of critically high alcohol consumption. METHODS This retrospective cohort study included 88,647 males and 88,925 females with dipstick urinary protein ≤ ± and estimated glomerular filtration rate ≥ 60 mL/min/1.73 m2 at their first annual health examinations between April 2008 and March 2010 in Japan. The exposure was the self-reported alcohol consumption. The outcome was proteinuria defined as dipstick urinary protein ≥ 1 + or ≥ 2 +. RESULTS During median 1.8 years (interquartile range 1.0-2.1) of the observational period, 5416 (6.1%) males and 3262 (3.7%) females developed proteinuria defined as dipstick urinary protein ≥ 1 +. In males, a U-shape association between alcohol consumption and proteinuria was observed in a multivariable-adjusted Poisson regression model [incidence rate ratio (95% confidence interval) of rare, occasional, and daily drinkers with ≤ 19, 20-39, 40-59, and ≥ 60 g/day: 1.00 (reference), 0.86 (0.79-0.94), 0.70 (0.64-0.78), 0.82 (0.75-0.90), 1.00 (0.90-1.11), and 1.00 (0.85-1.17), respectively], whereas a J-shape association was observed in females [1.00 (reference), 0.81 (0.75-0.87), 0.74 (0.64-0.85), 0.93 (0.78-1.11), 1.09 (0.83-1.44), and 1.45 (1.02-2.08), respectively]. Similar associations with dipstick urinary protein ≥ 2 + were shown in males and females. CONCLUSIONS Moderate alcohol consumption was associated with lower risk of proteinuria in both males and females. Females with ≥ 60 g/day of high alcohol consumption were at higher risk of proteinuria, whereas males were not. Females were more vulnerable to high alcohol consumption, than males.

Abstract
Hops (Humulus lupulus L.) is by far the greatest contributors to the bitter property of beer. Over the past years, a large body of evidence demonstrated the presence of taste receptors in different locations of the oral cavity. In addition to the taste buds of the tongue, cells expressing these receptors have been identified in olfactory bulbs, respiratory and gastrointestinal tract. In the gut, the attention was mainly directed to sweet Taste Receptor (T1R) and bitter Taste Receptor (T2R) receptors. In particular, T2R has shown to modulate secretion of different gut hormones, mainly Glucagon-like Peptide 1 (GLP-1), which are involved in the regulation of glucose homeostasis and the control of gut motility, thereby increasing the sense of satiety. Scientific interest in the activity of bitter taste receptors emerges because of their wide distribution in the human species and the large range of natural substances that interact with them. Beer, whose alcohol content is lower than in other common alcoholic beverages, contains a considerable amount of bitter compounds and current scientific evidence shows a direct effect of beer compounds on glucose homeostasis. The purpose of this paper is to review the available literature data in order to substantiate the novel hypothesis of a possible direct effect of hop-derived bitter compounds on secretion of GLP-1, through the activation of T2R, with consequent improvement of glucose homeostasis.
