The number of people living with diabetes has tripled since 2000, leading to enormous financial ramifications: the global cost of the disease is $850 billion each year. The latest estimates from the International Diabetes Federation indicate that one in 11 adults worldwide have diabetes; most have type 2 diabetes, which is strongly linked to obesity and lack of exercise. There is a strong link between type 2 diabetes and cardiovascular disease, as people with diabetes are more than twice as likely to develop cardiovascular disease and lower life expectancy.
A study published in Diabetologia, conducted by researchers from the National Institute of Public Health of the University of Southern Denmark, suggests that people who drink three to four times a week are less likely to develop type 2 diabetes than those who never drink.
The study, which surveyed over 70,000 people on alcohol intake, found that wine was particularly beneficial—as it likely plays a role in helping manage blood sugar. The study does note, however, that drinking frequency has an independent effect from the amount of alcohol taken: the effects are more beneficial when drinking the alcohol in four portions, rather than all at once.
