Diabetes mellitus - often referred to simply as diabetes - is a condition in which the body either does not produce any insulin (Type 1) or not enough insulin. Insulin is a hormone produced in the pancreas to overcome the underlying insulin resistance of the cells in the body (Type 2). Insulin enables glucose (sugar) to enter the cells in order to be stored as glycogen or oxidized for energy. These defects cause glucose to accumulate in the blood, inevitably leading to serious complications. The positive effects of moderate wine and other alcoholic beverage consumption are only relevant for individuals with type-2 diabetes.


Type 2 Diabetes


The underlying defect is insulin resistance due to obesity and lack of exercise. Insulin resistance means that the cells do not respond to the insulin signal. In return, the pancreas tries to overcome this resistance by increasing the insulin output which enables the glucose to enter the cells. Once the beta-cells cannot compensate the high demand of insulin for proper function, the glucose will remain in the blood leading to an increased blood sugar level. Approximately 90% of all cases of diabetes worldwide are type 2.


In 2010, the International Diabetes Federation estimated the global prevalence of diabetes mellitus at 6.6% in adults. Type-2 diabetes is now one of the most common non-communicable diseases in the world and a major cause of premature illness and death in most countries. To prevent diabetic complications and premature death, patients are recommended to adopt a healthy lifestyle.  


Evidence from randomized-controlled intervention studies as well as from population studies have demonstrated that light to moderate consumption of alcoholic beverages will improve insulin sensitivity in insulin resistant people. Accordingly, large prospective studies have shown a reduced risk for developing the metabolic syndrome (MS, name for a group of risk factors that raise the risk for heart disease, stroke and diabetes. A metabolic syndrome exists when at least 3 of the following risk factors are present: overweight, high triglyceride level, elevated plasma glucose level,  low HDL cholesterol level and high blood pressure) . A moderate intake of  wine as well as other alcoholic beverages exerts a beneficial effect on MS. In addition, large population studies suggest that light to moderate consumption of alcoholic beverages is associated with a lower diabetic risk than abstaining or heavy drinking, independently of the type of alcoholic beverage consumed. Meta-analyses reported a J-shaped relationship for men and women with a reduced risk for a moderate intake of alcoholic beverages and an increased risk for more than 50-60 g/d. With regards to wine and diabetes, most studies found  beneficial effects. But not only the risk of developing type 2 diabetes is decreased with moderate drinking; it may also reduce CHD and CVD mortality in diabetics as well as potential cardiac complications relating to diabetes. This is especially important considering that coronary heart disease (CHD) is the leading cause of death among individuals with type-2 diabetes, who also have a 4-fold increased risk of having a heart attack or stroke. Research indicates that this risk decreases considerably when they consume wine moderately with meals.


Considering the world-wide epidemic of type 2 diabetes which is expected to rise even further and is associated with major health care costs, preventing diabetes is a major public health issue. It seems that drinking wine in moderation could  help reduce type 2 diabetes and thereby contribute to public health.

AIMS/HYPOTHESIS: Alcohol consumption is inversely associated with diabetes, but little is known about the role of drinking patterns. We examined the association between alcohol drinking patterns and diabetes risk in men and women from the general Danish population. METHODS: This cohort study was based on data from the Danish Health Examination Survey 2007-2008. Of the 76,484 survey participants, 28,704 men and 41,847 women were eligible for this study. Participants were followed for a median of 4.9 years. Self-reported questionnaires were used to obtain information on alcohol drinking patterns, i.e. frequency of alcohol drinking, frequency of binge drinking, and consumption of wine, beer and spirits, from which we calculated beverage-specific and overall average weekly alcohol intake. Information on incident cases of…
BACKGROUND The relationship between alcohol consumption and metabolic syndrome (MetS) remains controversial. This study investigated the relationship between alcohol consumption and MetS components and prevalence. MATERIAL AND METHODS We analyzed 10 037 subjects (3076 MetS and 6961 non-MetS) in a community-based cohort. MetS was defined according to the ATP III Guidelines. Subjects were divided according to amount of alcohol consumption; non-drinker, very light (0.1-5.0 g/day), light (5.1-15.0 g/day), moderate (15.1-30.0 g/day), and heavy drinker (>30 g/day). Multiple logistic regression models were performed to estimate odds ratios (ORs) and confidence intervals (CIs). The analyses were performed in men and women separately. SPSS statistical software was used for analyses. RESULTS The prevalence of MetS in both males and females was associated with…
BACKGROUND/OBJECTIVES: It is unknown if wine, beer and spirit intake lead to a similar association with diabetes. We studied the association between alcoholic beverage preference and type 2 diabetes incidence in persons who reported to consume alcohol. SUBJECTS/METHODS: Ten European cohort studies from the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States were included, comprising participant data of 62 458 adults who reported alcohol consumption at baseline. Diabetes incidence was based on documented and/or self-reported diagnosis during follow-up. Preference was defined when 70% of total alcohol consumed was either beer, wine or spirits. Adjusted hazard ratios (HRs) were computed using Cox proportional hazard regression. Single-cohort HRs were pooled by random-effects meta-analysis. RESULTS: Beer, wine…
AIMS/INTRODUCTION: Previous meta-analyses identified an inverse association of total alcohol consumption with the risk of type 2 diabetes. The current study further explored the relationship between specific types of alcoholic beverage and the incidence of type 2 diabetes. MATERIALS AND METHODS: A search of PubMed, Embase and Cochrane Library databases from January 1966 to February 2016 was carried out for prospective cohort studies that assessed the effects of specific types of alcoholic beverage on the risk of type 2 diabetes. The pooled relative risks with 95% confidence interval were calculated using random- or fixed-effect models when appropriate. RESULTS: A total of 13 prospective studies were included in this meta-analysis, with 397,296 study participants and 20,641 cases of type 2 diabetes.…
Background Although alcohol consumption is commonly encountered in clinical practice, few studies have investigated the clinical significance of alcohol intake on the use of the hemoglobin A1c (HbA1c) level. Objectives This study was performed to investigate the association between alcohol intake and HbA1c level in the general population. Methods Among the 24,594 participants who participated in the 2011-2013 Korea National Health and Nutrition Examination Survey (KNHANES), 12,923 participants were analyzed in this study. We excluded diabetic patients currently taking antidiabetes medication. We compared the HbA1c level and proportions of patients with an HbA1c level of =5.7%, =6.1%, and =6.5% according to the fasting plasma glucose (FPG) concentration range and the amount of alcohol intake. The average amounts of daily alcohol…
