Beer: what was actually tested

Most of the research on this page did not test a pint of ordinary beer. The trial that cut fasting insulin by 11.1 percent in 41 adults with type 2 diabetes used an alcohol-free beer reformulated with isomaltulose, and its comparison arm was ordinary alcohol-free beer rather than going without. The four-week trial in 36 overweight adults read out on alcohol-free beer as well, and what it found was a mild shift in red blood cell membrane lipids with no change in membrane fluidity. When 33 men at high cardiovascular risk drank beer at 30 g of alcohol a day for four weeks, circulating endothelial progenitor cells rose by 8 units, the alcohol-free version raised them by 5, and gin carrying the same alcohol did nothing. It was measured in cells in the blood, and nobody in that trial got ill or stayed well. We hold no trial of what drinking beer does to a person's overall risk of disease or death, and nothing here is a reason to start. The WHO Regional Office for Europe says there is no safe amount of alcohol that does not affect health, and it classes alcohol as a Group 1 carcinogen. The amounts above are what those trials fed: 30 g of alcohol a day for four weeks, a little over two US standard drinks of about 14 g each, and 22 fl oz (660 mL) a day for men and 330 for women over another four. The CDC says there is no known safe amount of alcohol in pregnancy, beer included. The US alcohol institute warns that alcohol reacts with common medicines, among them diabetes drugs, pain relievers such as acetaminophen and the antibiotic metronidazole.

The numbers, per 3.5 oz (100 g)

As people eat it, per 3.5 oz (100 g)

What a real portion looks like

• The US alcohol institute (NIAAA) defines one standard drink as about 14 g of pure alcohol, the amount in a 12-ounce beer at 5% alcohol, so a 12-ounce craft beer at 10% counts as two drinks. — US drinkers Evidence E source
  One standard drink = about 14 g pure alcohol = 12 fl oz of 5% beer. A 12 oz beer at 10% = two standard drinks

• In 12 healthy volunteers, 14 fl oz (400 mL) of beer after a solid meal slowed the stomach emptying that meal, while the passage from mouth to caecum was unchanged. — 12 healthy volunteers per examination block, given a 1485 kJ solid meal followed by 14 fl oz (400 ml) beer at 4.7% vol, 6.8 fl oz (200 ml) red wine or 3.4 fl oz (100 ml) whisky (n = 12 per block) Evidence B source

The bottom line

Two reviews went looking for mold toxins in beer and found them. Aflatoxin B1 turned up in 26.00 percent of samples worldwide at a pooled 0.469 micrograms per liter, and there the margin of exposure fell below the acceptable 10,000 in every country assessed, worst in Malawi, Brazil and Cameroon. Deoxynivalenol was in 67.38 percent of samples across 26 papers at a mean 14.658 micrograms per liter, and that one stayed below the level of concern and has been falling over time. The two verdicts genuinely disagree, and we are not going to average them for you. The clearest harm here needs no statistics. A review of 44 published cases describes beer potomania, where heavy beer drinking with very little food drops blood sodium far enough to bring on confusion and seizures. In 5 of those 44 the sodium was then corrected too fast and the correction itself damaged the brain. This is what drinking in place of eating looks like at its worst. Some smaller effects are well measured and stay small. In 12 healthy volunteers, 14 fl oz (400 mL) of beer after a solid meal slowed the stomach emptying that meal, while passage from mouth to caecum was unchanged. In the Framingham cohorts beer was the leading dietary source of silicon for men, who averaged 30 and 33 mg a day in the two cohorts, and about 41 percent of ingested silicon showed up in urine. What that silicon then does to a person was not measured. Two common beliefs did not survive testing. Over 10 weeks, 73 young adults training twice a week gained the same maximal oxygen uptake whether they drank 11 to 22 fl oz (330 to 660 mL) of beer on weekdays, plain ethanol, alcohol-free beer or sparkling water. Across 16 reports, overall diet quality looked broadly similar in moderate beer drinkers and in abstainers, and the biochemical side had too few studies to pool at all. As a recovery drink beer works only once it has been altered. After cycling that cost 2 percent of body mass, low-alcohol beer with 50 mmol/L of added sodium left 12 men passing 49 fl oz (1450 mL) of urine against 67 fl oz (1986 mL) for plain mid-strength beer, so the salt did the work. Some people should not drink at all. The 2025-2030 Dietary Guidelines for Americans name pregnant women, people recovering from alcohol use disorder or unable to control how much they drink, and people on medicines that interact with alcohol, and they advise everyone else to drink less. The US alcohol institute lists what those interactions look like. With diabetes medicines, blood sugar can fall abnormally low. With pain relievers there is a risk of stomach bleeding and ulcers, and of liver damage with acetaminophen. With metronidazole and some other infection medicines it lists fast heartbeat, sudden changes in blood pressure, vomiting, headache and flushing. MAOI antidepressants such as phenelzine can cause serious heart-related side effects with alcohol, and dangerously high blood pressure with the tyramine the institute says beer contains. The same institute counts one standard drink as about 14 g of alcohol, the amount in a 12-ounce beer at 5 percent, so a 12-ounce craft beer at 10 percent counts as two. The American Heart Association says binge drinking or 3 or more drinks a day is consistently tied to worse outcomes in every cardiovascular disease studied. We still hold nothing on children or teenagers, older people, or kidney or liver disease, and for those the answer belongs to the person treating you. We also hold nothing on how composition varies between styles and brands, nothing on brewing, and nothing that puts a real glass beside the laboratory doses above. On kidney stones an umbrella review of 17 meta-analyses graded beer intake suggestive protective, which is the weakest credibility grade that method hands out, and that is the whole of it.
