ALCOHOL | INSULEAN

 

Zero Alcohol is Healthy

In September 2018, a major international study was published in The Lancet. The authors concluded that any amount of alcohol is harmful. ”We found that the risk of all-cause mortality, and of cancers specifically, rises with increasing levels of consumption, and the level of consumption that minimises health loss is zero”. Those of us who enjoy a glass of red wine a few times a week ”to help keep the heart healthy” were dismayed.

However, this is the latest ‘expert opinion’, since the last ‘expert opinion’.

 

Zero Alcohol is Harmful

In April 2018, another published study showed the exact opposite, that there were clear harms to non-drinkers and that ”the risk of early death from drinking begins to rise at a level above 100g of alcohol per week (12.5 units)”. This paper, also published in The Lancet medical journal, concluded that five standard 175ml glasses of wine or five pints a week is the upper safe limit – about 100g of alcohol, or 12.5 units in total. More than that raises the risk of stroke, fatal aneurysm (a ruptured artery in the chest), heart failure and death. Note that the NHS recommends no more than 14 units of alcohol a week. That’s about a glass of wine a day.

So, which is it? To drink or not to drink?

How much is too much?

Before you fully embrace teetotalism, consider this. The press release of the latter study only showed the relative risk of developing an alcohol-related illness, such as diabetes.

Comparing zero drinks to one drink

The risk of developing one of the 23 alcohol-related health problems was 0.5% higher, i.e,

  • 914 in 100,000 would develop a condition in one year if they did not drink.
  • 918 in 100,000 who drank one alcoholic drink a day would develop a condition.

 

Comparing one drink to two drinks

The absolute (actual) risk, increases from 0.918% (one drink) to 0.977% (two drinks). In other words, if you have two drinks a day, your risk ‘jumps’ from less than 1% to less than 1%!

The absolute risks are very small. Furthermore, the lack of reporting of absolute risk makes it difficult for readers to understand the actual dangers of drinking alcohol. Relative risk is useless and only acts to amplify the absolute risk. The reporting of relative risk is confusing and misleading, yet unacceptably prevalent in published studies.

This increase in risk is tiny. On this one, I concur with the current NHS recommendations. Drink sensibly.

There is no safe level of driving, but the government does not recommend that people avoid driving.

Drink Sensibly

British social life is been entirely organised around alcohol. This isolates non-drinkers and subjects them to intense peer pressure. There is no doubt of the harms of excessive alcohol, but the vast majority of us enjoy the pleasure of a drink, to relax or help as a social lubricant. There is no significant harm in that, in my opinion.

Public health policy remains necessary because the harms of excessive alcohol intake cannot be underestimated. Punitive taxation does work, but is often met with resistance because those who drink sensibly are equally penalised. Nevertheless, several measures are in place to reduce the numbers who drink, such as

  • Increasing prices.
  • Taxation.
  • Setting minimum units pricing (the price according to the strength of the drink).
  • Restrictions on marketing.
  • Restricting the places where people can buy alcohol.
