Alcoholic beverages have been consumed for thousands of years, attracting great human interest for social, personal, and religious occasions. In addition, they have long been debated to confer cardioprotective benefits. The French Paradox is an observation of a low prevalence of ischemic heart disease, with high intakes of saturated fat, a phenomenon accredited to the consumption of red wine. Although many epidemiological investigations have supported this view, others have attributed it to beer or spirits, with many suggesting that the drink type is not important. Although excessive consumption of alcoholic beverages is commonly regarded to be detrimental to cardiovascular health, there is a debate as to whether light-to-moderate intake is cardioprotective. Although there is extensive epidemiological support for this drinking pattern, a consensus has not been reached. On the basis of published work, we describe the composition of wine and the effects of constituent polyphenols on chronic cardiovascular diseases

BACKGROUND: Limited research is available on children's alcohol-related knowledge and alcohol-related norms, yet a better comprehension of these factors may be crucial in explaining alcohol use later in life. This study provides insights into alcohol-related knowledge and alcohol-related norms in four- to six-year-olds.

METHODS: Participating children (N=329; 48.9% boys) were shown, on a tablet, 18 drawings depicting 72 male and female adults and/or children in various situations and were asked to indicate what the depicted persons drank by touching one of 12 depicted beverages (four alcoholic; eight non-alcoholic). Subsequently, the children were asked to name the beverages and indicate whether they contained alcohol.

RESULTS: Children identified 30.7% of the alcoholic beverages (i.e., beer, champagne, red wine, and white wine) correctly by name and they identified 41.6% of the alcoholic beverages correctly as alcohol-containing. Children more often correctly identified the name and non-alcoholic content of non-alcoholic beverages compared to the name and alcoholic content of alcoholic beverages. No sex differences emerged in the correct identification of the name and the content of both alcoholic beverages and non-alcoholic beverages. However, alcohol-related knowledge was age-graded. Alcoholic beverages were more often assigned to male adults (39.2%) than to female adults (24.8%) or to children (13.2%). Additionally, alcoholic beverages were more often assigned to adults depicted in the presumably more appropriate situations (e.g., 'when having an indoor party': 37.0%) than to those depicted in the presumably more inappropriate situations (e.g., 'when driving a car': 28.6%).

CONCLUSIONS: Four- to six-year-olds already have knowledge about alcohol and its norms in adult culture. Insight into the development of children's alcohol-related knowledge and alcohol-related norms over time is required to investigate the transitions to alcohol expectancies, drinking motives, and alcohol initiation often occurring in adolescence.

Flavonoids are bioactive compounds found in foods such as tea, red wine, fruits and vegetables. Higher intakes of specific flavonoids, and flavonoid-rich foods, have been linked to reduced mortality from specific vascular diseases and cancers. However, the importance of flavonoid-rich foods, and flavonoids, in preventing all-cause mortality remains uncertain. As such, we examined the association of intake of flavonoid-rich foods and flavonoids with subsequent mortality among 93 145 young and middle-aged women in the Nurses' Health Study II. During 1 838 946 person-years of follow-up, 1808 participants died. When compared with non-consumers, frequent consumers of red wine, tea, peppers, blueberries and strawberries were at reduced risk of all-cause mortality (P<0.05), with the strongest associations observed for red wine and tea; multivariable-adjusted hazard ratios 0.60 (95 % CI 0.49, 0.74) and 0.73 (95 % CI 0.65, 0.83), respectively. Conversely, frequent grapefruit consumers were at increased risk of all-cause mortality, compared with their non-grapefruit consuming counterparts (P<0.05). When compared with those in the lowest consumption quintile, participants in the highest quintile of total-flavonoid intake were at reduced risk of all-cause mortality in the age-adjusted model; 0.81 (95 % CI 0.71, 0.93). However, this association was attenuated following multivariable adjustment; 0.92 (95 % CI 0.80, 1.06). Similar results were observed for consumption of flavan-3-ols, proanthocyanidins and anthocyanins. Flavonols, flavanones and flavones were not associated with all-cause mortality in any model. Despite null associations at the compound level and select foods, higher consumption of red wine, tea, peppers, blueberries and strawberries, was associated with reduced risk of total and cause-specific mortality. These findings support the rationale for making food-based dietary recommendations.

BACKGROUND: Ethanol in alcoholic beverages is a known carcinogen, but its association with aggressive prostate cancer (APC) is uncertain. Recent studies have shown a modest increase in risk of APC associated with heavy alcohol intake while association for beverage types remain inconsistent.

METHODS: Using a case-control design and self-administered questionnaire, we examined the association between APC (high grade and/or advanced stage) and frequency and quantity of alcohol intake 2 years prior to enrolment. Furthermore, we delineated the relationships for beverage-specific intakes of beer, red wine, white wine and spirits.

RESULTS: The study included 1282 APC cases and 951 controls. Beer intake frequency of 5 days per week was associated with increased risk compared with no beer intake (odds ratio=1.66, 95% confidence interval: 1.12-2.48) whereas wine was protective at all frequencies of consumption compared with those with no wine intake. For every 10 g per week ethanol intake from beer increase, the odds of advanced PC rose by 3% (OR=1.03, 95% CI: 1.02-1.05). No such increased risk was observed for red or white wine while a marginal dose-response relationship was found for spirits (OR=1.03, 95% CI: 0.99-1.07).

CONCLUSIONS: Heavy beer and possibly spirits consumption is associated with increased risk while no dose-response relationship was found for red or white wine. Wine drinkers at all frequencies have a decreased risk of APC compared with those who did not drink wine.Prostate Cancer and Prostatic Diseases advance online publication, 18 April 2017; doi:10.1038/pcan.2017.12
