Plain English Summary
Background and study aims
Cardiovascular (heart and blood vessel) disease remains the most common cause of death worldwide. Coronary atherosclerosis is when the blood vessels around the heart become blocked and stiffened. This is a major cause of cardiovascular disease. Drinking alcohol in moderate amounts has been shown to reduce inflammation, reduce blood clot formation and improve cholesterol levels, all of which are involved in atherosclerosis. It is known that moderate wine consumption is associated with improved cardiovascular health. Other studies have shown a similar effect for other alcoholic drinks such as beer and spirits. However it is not known whether the Brazilian spirit cachaça has the same effect. This study will investigate the levels of substances in the body that are associated with cardiovascular health or disease after periods of moderate consumption of cachaça and red wine, separately, in the same participants.
Who can participate?
Healthy adults who are willing to drink no alcohol for three separate weeks and to drink wine and cachaça daily at the required amounts for 28 days.
What does the study involve?
The participants will be randomly allocated to one of two groups. Both groups will have 7 days of not drinking any alcohol. One group will drink cachaça daily for 28 days and the other group will drink red wine daily for 28 days. Then both groups will drink no alcohol for 7 days, then the group who drank cachaça in the first period will drink red wine daily for 28 days and the the group who drank red wine in the first period will drink cachaça daily for 28 days.
What are the possible benefits and risks of participating?
There will be no payment for those wishing to participate in the study. Alcoholic beverages will be provided by the study. Side effects are the same as related to the consumption of any alcoholic beverage. The abuse of the beverages provided by the study is totally discouraged by the researchers.
Where is the study run from?
Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP) [Hospital of the Faculty of Medicine of the University of Sao Paulo] (Brazil)
When is the study starting and how long is it expected to run for?
February 2018 to December 2020

Randomized clinical trial evaluating the effect on many molecular markers well established as atherosclerosis/cardiovascular risk factors of moderate different alcoholic beverages consumption on healthy subjects.
Could cachaça positively modify traditional cardiovascular biomarkers in the same proportion as wine?

This is a crossover study. Participants will be randomized using computer software to determine whether they consume red wine or cachaça in the first intervention period. Each participant will start with 7 days of abstinence from all alcohol , then a period of 28 days of moderate consumption of red wine or cachaça, then another 7 days of abstinence, then 28 days of the other alcoholic beverage. Beverages will be provided by the study organizers. They will consume 28 g of alcohol (2 servings, equivalent to 90 ml of cachaça 40% or 230 ml of 12% wine) per day for men and 14 g for women (1 serving per day) in the form of wine or cachaça. The total duration of treatment is 5 weeks and there is no additional follow-up.
