The age old question of alcohol consumption, diabetes, risk factors, insulin resistance and complications. I personally enjoy a beer – once every couple of months – but don’t make alcohol part of my normal routine. However, researchers have completed a massive study involving 38,000 men over a four years period and found that those increased their alcohol consumption had a lower incidence of Diabetes:
RESULTS A total of 1,905 cases of type 2 diabetes occurred during 428,497 person-years of follow-up. A 7.5 g/day (approximately half a glass) increase in alcohol consumption over 4 years was associated with lower diabetes risk among initial nondrinkers (multivariable hazard ratio [HR] 0.78; 95% CI: 0.60–1.00) and drinkers initially consuming <15 g/day (HR 0.89; 95% CI: 0.83–0.96), but not among men initially drinking ≥15 g/day (HR 0.99; 95% CI: 0.95–1.02; Pinteraction < 0.01). A similar pattern was observed for levels of total adiponectin and hemoglobin A1c, with a better metabolic profile among abstainers and light drinkers who modestly increased their alcohol intake, compared with men who either drank less or among men who were already moderate drinkers and increased their intake. Likewise, compared with stable light drinkers (0–4.9 g/day), light drinkers who increased their intake to moderate levels (5.0–29.9 g/day) had a significantly lower risk of type 2 diabetes (HR 0.75; 95% CI: 0.62–0.90).
CONCLUSIONS Increases in alcohol consumption over time were associated with lower risk of type 2 diabetes among initially rare and light drinkers. This lower risk was evident within a 4-year period following increased alcohol intake.
The results does seem consistent with what we’ve seen in the past with the exception that an increase rather than absolute consumption was studied. I don’t know that this should motivate a change in dietary habits for those who are undiagnosed or have pre-diabetes but it certainly will be used by some to justify their chosen lifestyle.
