Red and white wines: The effect of moderate consumption on human health

Moderate wine consumption is often associated with healthy lifestyle habits. The role of wine as a healthy drink is mainly due to its bioactive compounds, which differ according to various viticultural and enological factors.
A study analysed the differences in bioactive compounds of white and red autochthonous Croatian wines, differing in terms of the grape variety and production technology. In addition, researchers explored the effect of their moderate consumption (200 mL per day) over the course of six weeks on some aspects of health in sixty-six healthy individuals.
Participants were divided into eight groups depending on the wines consumed, with one group acting as a non-consuming control group. Medical examination and laboratory tests were performed before the start and at the end of the consumption period.
Systolic and diastolic blood pressure, total cholesterol, and LDL concentrations decreased. Additionally, an increase in HDL concentrations, and serotonin and dopamine levels, was observed. Liver enzymes ALT, ALP, and GGT levels did not significantly increase in consumer groups, although alcohol concentration was relatively high in all the wines.
The authors say that these results support the beneficial effects of wine-derived bioactive compounds on some health aspects resulting from moderate white and red wine consumption.
