Be
a Responsible drinker
| To drink responsibly |
| |
Decide your drink limit
before you start drinking |
| |
Limit yourself to not
more than two standard drinks per day |
| |
| One standard
drink is equivalent to: |
| - |
1 can of beer;
or |
| - |
120 mls of
wine; or |
| - |
30 mls of
spirits |
|
| |
Eat while you drink.
Don't drink on an empty stomach |
| |
Sip one drink slowly
over a long period of time. Don't gulp |
| |
Avoid drinking spirits
neat. Mix them with soda water, ginger ale or fruit juices |
| |
Alternate your drinks
with non-alcoholic ones |
| |
Don't drink if you are
taking drugs, like antihistamines which are prescribed for flu |
| |
Never drive after
drinking |
| |
If you plan to drink,
don't drive |
| |
| - |
Call a cab |
| - |
Catch a ride
with a friend who hasn't been drinking |
| - |
Call home and
have a sober family member come and get you |
| - |
Stay overnight |
| - |
Better still,
ensure that the designated driver for your group agrees
ahead of time, not to drink on that occasion, so that he
can drive your group home safely when the party ends. |

How does alcohol affect our
ability to drive? What is the legal limit of alcohol in the blood?
Alcohol impairs good judgment and dulls alertness. It results in a
lack of muscle co-ordination and double vision in one's eyesight. Alcohol
slows down reaction time. In Singapore, the legal limit of alcohol in the
blood is 80mg of alcohol per 100ml of blood. In general, for a 60-70 kg
person, about 1 ½ large bottle of beer (which is about 1000ml) consumed
over half an hour can give rise to a blood alcohol concentration of 80mg
of ethanol per 100ml of blood.

Sensible
beer drinking is healthy
One 25 cl
glass of beer is better than none. Two are even better, but more than
three is ill advised.
Beer is not unhealthy. On the contrary, if drunk moderately it acts
against the occurrence of heart and circulatory diseases, possibly plays a
protective role against some forms of cancer, and reduces the general
level of mortality. This has been shown by various scientific studies, the
main ones of which you will find in this document.
That sensible beer drinking is also good for the soul does not need any
scientific confirmation.
Beer
also provides a number of important nutrients, including carbohydrates,
amino acids, minerals and vitamins. It is not without reason that beer is
called liquid bread. Beer does not make you fat either: 1 litre of lager
contains fewer calories than the same quantity of wine or soft drink.

Moderate
beer drinking is good for the heart and blood vessels
In comparison to non-drinkers and heavy drinkers,
moderate beer drinking reduces the risk of heart and circulatory diseases,
and death due to heart and circulatory diseases. This has been
demonstrated in dozens of studies that hundreds of thousands of people
participated in.
This protective effect is very probably an
effect of the alcohol itself because it is also found among wine drinkers
and spirits drinkers. Whether this protective effect is more pronounced in
the one drink or the other is difficult to say.
A number of studies have indeed made a distinction between the type of
alcohol consumption - beer, wine or spirits - and the risk of heart and
circulatory diseases. In general it can be said that the risk seems to be
reduced just as much with the three types of alcoholic drink. It is not
the type of drink, but the alcohol that provides the protective effect.
The influence of other non-alcoholic drinks on heart and circulatory
diseases is not yet clear on the other hand.

Beer
reduces the risk of cancer
Hops, the component of beer that gives it its bitter flavour, contain
flavanoids, which belong to phyto-oestrogens. Phyto-oestrogens are
biologically active substances of a vegetable origin that imitate the
action of the female hormone oestrogen. Many kinds of favourable effects
are attributed to phyto-oestrogens. Thus a diet rich in phyto-oestrogens
protects against heart and circulatory diseases and cancer, and a high
intake of these substances moderates menopausal complaints in older women.
These effects have been scientifically studied on a wide basis. Breast
cancer occurs significantly less frequently in women with a diet rich in
phyto-oestrogens (1) and the risk of cervical
cancer is lower in women whose diet contains a lot of fibre and soya (2).
Soya is rich in phyto-oestrogens. In population groups where a lot of soya
is eaten, fewer men have prostate cancer (3).
The best known source of phyto-oestrogens is soya but hops are also rich
in phyto-oestrogens. As hops are an important component in beer, the
question arises as to whether beer drinkers also benefit from the
favourable effects of phyto-oestrogens on health. Scientists are ready for
a new challenge here. Studies are underway to examine whether beer reduces
the risk of certain cancers as a result of the phyto-oestrogens.

Beer,
the remedy for all sorts of ailments
In Babylon
and Egypt, long considered as the birthplace of beer, the drink was
offered to the gods and was mainly used by kings and at important
festivals. The Egyptians also attributed a therapeutic effect to beer, and
women of the upper classes used it for cosmetic purposes, ie. to freshen
their skin and reduce the risk of certain skin conditions.
In ancient
Greece Hippocrates used beer as a remedy to facilitate diuresis and the
drink was also considered to act against fever. Alcohol was also used at
this time to heal wounds. Aretus of Capadocia recommended it for diabetes
and migraine.
In the Middle
Ages beer was used as a stimulant to improve mood. Appetite generating and
calming properties were attributed to the hop, a component of beer. Up
until a hundred years ago, hop-filled cushions were recommended for
sleeping disorders.
In
the beginning of this century, the harmful consequences of alcohol abuse
came to light, and medicine adopted a sceptical attitude towards alcoholic
drinks, including beer. The emergence of powerful medicines further pushed
out the use of alcohol as a remedy. It is only in the last few years that
there has been renewed interest for the beneficial effect of alcohol on
health.

Nutritional
aspects of beer
For a large
section of the Belgian population, beer is a not unimportant component of
the diet. The alcohol in beer provides calories and influences the
consumption of other nutrients.
Soft
drinks contain twice as many calories as lager.
The
energy value of alcohol is 7 kcal/g. Four 25 cl glasses of lager (around
40 g of alcohol) provide as many calories as 70 g of sugar. Four glasses
of a soft drink, coke for example, contain as many calories as 132 g of
sugar. This is around twice as much as four glasses of lager. But there is
something special about the energy value of alcohol.
When alongside the basic intake of 2,200 kcal/day, a further 2000 kcal are
added in the form of beer, then this person will not get as fat as if he
had consumed the 2000 extra calories in the form of chocolate. This has
been found experimentally, but there is currently no explanation for it.
Presumably alcohol is broken down less efficiently than sugar. Moderate
beer drinkers thus do not need to worry about getting fat straightaway.

Is
there such a thing as a beer belly?
Alcohol contains 7 kilocalories per gramme. Forty grammes of alcohol
(which corresponds to four 25 cl glasses of lager) contains as many
calories as 70 g of sugar. As a comparison, four glasses of soft drink (eg.
coke) contain as many calories as 132 g of sugar, which is twice as many
as four glasses of lager. Beers with a higher alcohol content contain more
calories. Wines and spirits contain more calories than beer. Drinking beer
in moderate quantities will not necessarily mean putting on weight, which
has been confirmed in recent research on beer consumption and obesity. In
a group of people who had drunk beer over the previous year there were
fewer obese people (> 30 kg/m2) than in the group that had not drunk
any beer at all. After correcting for all co-factors (such as smoking,
age, sex, etc) it was found that beer consumption does not increase the
amount of obesity. The data will be looked at later in this chapter.
An isocalorific diet means that the excessive drinker leaves out other
(frequently essential) components of food and opts for a more
consistent diet.
The idea that beer makes people fat
probably has its origins in the lifestyle and eating habits that are often
coupled with beer drinking. Drinking beer increases the appetite and
alcohol also relaxes control over our eating behaviour. Heavy beer
drinkers generally go for fatty calorific food (snacks, chips, sausages,
nuts, etc) and generally do little exercise. Research has also shown that
the bodies of people who drink a lot of beer burn less fat. The body is
probably inclined to burn the alcohol first. The excess fat has to go
somewhere and is accumulated above the abdominal muscles. The result is
well known.
The so-called beer belly is thus not a
direct effect of high beer consumption, but rather the unhealthy diet and
lifestyle coupled with it, in combination with reduced fat combustion by
the body. It is thus better to have beer as a component of the diet rather
than a stimulant consumed separately from meals (beer already has this
image).
