Beer drinking babes have more fun AND better bones...

As it soaks you to the bone

Women who drink moderate amounts of beer may be strengthening their bones, according to Spanish researchers.

Their study of almost 1,700 women, published in the journal Nutrition, found bone density was better in regular drinkers than non-drinkers.

But the team added that plant hormones in the beer rather than the alcohol may be responsible for the effects.

Experts urged caution, warning that drinking more than two units of alcohol a day was known to harm bone health.

Osteoporosis is a common problem for post-menopausal women, increasing the risk of disabling bone fractures later in life.

Further research

Scientists have been hunting for supplements which might help women maintain the strength of bones into old age.

The study authors, from the University of Extremadura in Caceres, said they did not recommend anyone drank beer to boost bone health, but said that ingredients of beer called phytoestrogens deserved further research.

They recruited volunteers with an average age of 48, and used ultrasound to measure the density of bones in their fingers.

The results were cross checked against factors such as their weight, age and alcohol use.

Women defined as "light" or "moderate" beer drinkers, covering consumption of up to 280 grams of alcohol a week - equivalent to up to five units a day, were found to have superior bone density to non-drinkers.

The findings echo those from earlier research projects, including one conducted at St Thomas' Hospital in London, which suggested that drinking an average of eight units a week of alcohol could be beneficial.

However, experts were quick to point out that the line between a "healthy" dose of alcohol and a damaging one might be very fine.

Health concerns

At 35 units a week, the upper limit of the "moderate" alcohol consumption defined by the study is double the recommended maximum for women.

Dr Claire Bowring, of the UK's National Osteoporosis Society, said that while the findings mirrored previous studies, it would not be recommending any woman to increase her alcohol consumption as a result.

"While low quantities of alcohol may appear to have bone density benefits, higher intakes have been shown to decrease bone strength, with an alcohol intake of more than two units per day actually increasing the risk of breaking a bone.

"There are also many other health concerns linked with alcohol which cannot be ignored."

Abstract

Objective

To study the effect of beer consumption on bone mass in a group of healthy women, by using phalangeal bone ultrasound to evaluate the amplitude-dependent speed of sound.

Methods

This was a cross-sectional study of 1697 healthy women (mean age 48.4 y, body mass index (BMI) 19.0–32.0 kg/m2), recruited in a clinical convenience sample and screened for the existence of disease and/or medication that would affect calcium metabolism. Of this total, 710 were premenopausal, 176 were perimenopausal, and 811 were postmenopausal. The women recruited completed a questionnaire that contained detailed sections on current cigarette, alcohol, caffeine, and nutrient consumption. In terms of current alcohol intake, the subjects were classified as moderate drinkers, light drinkers, and nondrinkers. Drinkers were also analyzed according to the kind of alcohol consumed: wine or beer.

Results

Quantitative bone ultrasound values were greater in the beer drinkers compared with the no beer and/or wine drinkers. Taking the amplitude-dependent speed of sound as a dependent variable, and age, BMI, gonadal status, intake of beer and wine, and number of cigarettes per day as independent variables, we found age (β = −1.52), BMI (β = −3.86), gonadal status (β = −27.47), and beer intake (β = 1.06) to be significant.

Conclusion

The greater bone density found in women beer drinkers might be a result of the phytoestrogen content of this alcoholic drink; this requires further investigation.
