Project description
It is generally accepted that moderate consumption of wine is beneficial to health, but it is still not clear how much the alcohol and the non-alcoholic compounds in the wine contribute to these benefits. Owing to the obvious concerns of excessive alcohol intake, it is attractive to explore the production of wine from which alcohol is removed, either partially or completely. The solution might thus lie in low and reduced-alcohol wines, but their marketing for health benefit requires research and evidence that proves similar or better outcomes on health or surrogate markers for health benefit, compared with the standard wines. Some obvious advantages of low-alcohol wine include reduced risk from alcohol related diseases, reduced calorie intake, possible safety for pregnant women, and advantages for consumers who, for health or religious reasons, cannot consume much or any alcohol.

The project for 2010 will test red cells from healthy humans with a specific concentration of one or more pro-oxidants with varying amounts of standard wines and their reduced-alcohol counterparts. The antioxidant capacity and the phenol concentrations of the wines will also be determined.
