Exploring the Influence of Alcohol Industry Funding in Observational Studies on Moderate Alcohol Consumption and Health.

How full is your glass? Portion sizes of wine, fortified wine and straight spirits at home in the Netherlands.

Objective: Alcohol consumption may be wrongly estimated because of inaccurate information on actual portion sizes. We compared portion sizes of wine, fortified wine and straight spirits poured at home with the Dutch standard drink sizes.

Design: Participants measured portion sizes of wine, fortified wine and straight spirits at home up to a maximum of three times and reported these via an online survey.
