Alcohol and health
Alcohol, harm and where to get help
What are the health risks of alcohol, and what does CiderHQ say about them?
In short
The World Health Organization states that there is no form of alcohol consumption that is risk-free, and its International Agency for Research on Cancer classifies alcoholic beverages, and the ethanol in them, in Group 1 — carcinogenic to humans — the same classification given to asbestos and tobacco.
CiderHQ follows that position. It publishes no health benefits for alcohol, in any context, for any style, at any level of consumption.
Anyone worried about their own drinking or someone else’s should speak to a general practitioner or contact a national alcohol support service. That is a more useful step than anything on this page.
The position, stated once
Alcohol is causally linked to a range of harms, and the World Health Organization states that no level of consumption can be considered safe for health. The International Agency for Research on Cancer classifies alcoholic beverages, and ethanol in alcoholic beverages, in Group 1: carcinogenic to humans.
The UK Chief Medical Officers frame their guidance in terms of low risk rather than no risk, and are explicit that the 14-unit weekly figure is a threshold for keeping risk low rather than a threshold below which there is none. They advise spreading any such consumption over three or more days, and having several drink-free days each week.
The US Dietary Guidelines for Americans state their limits as limits for people who already drink, note explicitly that the guidance is not a recommendation to start drinking, and state that drinking less is better for health than drinking more.
Those three positions differ in framing and agree in direction. CiderHQ takes the WHO framing as its baseline and reports the national guidance where readers need the specific figures.
What the harms are, in outline
Alcohol is associated with cancers of several sites, with liver disease, with cardiovascular and digestive conditions, with injury, and with dependence. The World Health Organization publishes the epidemiology, and it is a large literature.
Risk is related to quantity, and there is no threshold below which the association with cancer disappears. This is the specific finding behind the "no safe level" framing, and it is the point at which older public messaging about moderate drinking has been revised.
Patterns matter as well as totals. Heavy drinking concentrated into single occasions carries risks of injury and acute harm that the same quantity spread out does not, which is why the UK guidance addresses spreading consumption as well as limiting it.
Harm is not confined to the drinker. Alcohol contributes to road deaths, to violence and to harm within families, and public-health policy addresses those as well as the health of the individual.
The polyphenol argument, and why it is not made here
Cider contains phenolic compounds derived from the fruit — procyanidins, hydroxycinnamic acids, flavonols and others — and these are genuinely present, genuinely interesting, and central to how cider tastes. CiderHQ writes about them at length in its chemistry pillar.
They are frequently deployed in cider marketing as an argument that cider is good for you. That argument is not made on this site. A compound with studied properties in isolation does not confer those properties on an alcoholic drink containing it, and the ethanol in the same glass carries risks that no phenolic content offsets.
No health authority treats the polyphenol content of alcoholic drinks as a reason to drink them. Where the same compounds matter nutritionally, they are available from fruit, which contains no ethanol.
The same reasoning applies to every other version of the argument: that cider is natural, that it is made from fruit, that it contains no additives, or that a traditional method makes it wholesome. None of these bears on the health effects of the alcohol.
Where to get help
A general practitioner is the usual starting point in the United Kingdom, and the conversation is routine for them. Alcohol services can be accessed through a GP and in many areas directly, without a referral.
National health services publish self-assessment tools, information about what dependence looks like, and directories of local services. National charities operate confidential helplines for people worried about their own drinking and for people worried about someone else’s.
CiderHQ deliberately does not publish helpline numbers, because they change and a stale number is worse than none. Searching for the national alcohol support service in your own country, or asking a pharmacist or GP, will produce the current one.
Withdrawal from physical alcohol dependence can be medically dangerous and should not be attempted without advice. This is one of the few points in this section where the practical consequence of not asking a doctor is immediate.

What people ask next
Questions readers ask about the things this page mentions. Each one goes to the section that answers it rather than to a page written to receive the question.
- How do you work out the units in a cider, and why do uk and us measures differ — A UK unit is 10 ml — about 8 grams — of pure ethanol, and units are calculated by multiplying the volume in litres by the ABV. A 568 ml pint at 6 per cent is 3.4 units.
- What does the body do with alcohol, and why is it’s only cider a mistake at 7.5 per cent — Ethanol is absorbed from the stomach and small intestine into the bloodstream within minutes, and it is eliminated chiefly by liver enzymes at a rate that is roughly constant and cannot be increased at will.

Sources
What this page rests on. Where a source is marked as registered rather than read, CiderHQ is recording that the body is authoritative on the subject without claiming to have worked through the document itself. See our evidence policy for what each state means.
World Health Organization · health authority · passage verified 2026-08-24
The basis for CiderHQ publishing no health benefits for alcohol. Note carefully what this page does and does not carry: it states that no form of alcohol consumption is risk-free and that alcohol is an established carcinogen, but it does not itself set out the IARC classification. That is cited to IARC directly — see `iarc-alcohol-monograph`. The distinction matters because CiderHQ’s own rule is that a source is cited for what it actually says.
UK Chief Medical Officers’ low risk drinking guidelines
Department of Health and Social Care · health authority · retrieved 2026-08-24
The guidelines that set the UK 14-unit weekly figure, advise spreading consumption over three or more days, and state that the safest approach in pregnancy is not to drink at all. CiderHQ takes its health framing from here rather than from industry material.
NHS · health authority · passage verified 2026-08-24
The definition CiderHQ’s units calculator implements, read against the page rather than assumed: one UK unit is 10 ml or 8 g of pure ethanol, and units are ABV multiplied by volume in millilitres divided by a thousand — which is exactly the arithmetic in `engine/calculators.ts`.
Dietary Guidelines for Americans — alcohol
US Departments of Agriculture and Health and Human Services · health authority · registered as competent for this subject
Registered so CiderHQ can state that a US standard drink is 14 g of pure alcohol against the UK unit’s 8 g — a difference that makes cross-country drinking advice non-transferable.
A description of what is known, written for readers of legal drinking age. It is not medical advice and it is not an encouragement to drink. CiderHQ publishes no health benefits for alcohol, because current guidance from the major health authorities does not support them.
