So far, science has failed to lend credence to their claim. Now, a team of investigators sheds light on why studies have borne conflicting results when it comes to the effects of alcohol on heart health.
People usually have two copies of the gene, one inherited from each parent.
On the other hand, male drinkers with the E4 version of the gene had the highest LDL concentrations. Again, their level of ''bad'' cholesterol was higher than nondrinkers, regardless of other cholesterol-influencing factors. In women, the investigators found, alcohol did not have a substantial effect on LDL, as levels were significantly lower among both female drinkers and nondrinkers with the E2 variant compared with those with the E4 variant. The reasons behind the gender differences, however, are not clear. APOE E4 is one of the most important known risk factors for developing the neurodegenerative disorder.
