Alcohol on a plant based diet: what the doctors say
Alcohol on a plant based diet: what McDougall, Campbell, Barnard, Goldhamer and other doctors say about wine and beer, where they agree and differ.
Updated . For education only, not medical advice.
Our view
Wine, beer and spirits are made from plants, yet none of the doctors on this site counts them as part of a healthy plant based diet; Nathan Pritikin already called alcohol a drug rather than a food in 19821. The low-fat clinicians who treat patients with food, John McDougall, Alan Goldhamer and Jeff Novick, all argue against drinking, and T. Colin Campbell came round to the same view by 20232345.
The case for red wine does not convince them: Goldhamer points out that its resveratrol comes from grape skins you can eat, and Neal Barnard asked in 2014 whether the grape rather than the alcohol explains the small benefit seen in light drinkers36. Novick, Ornish and Goldhamer each offered other reasons why moderate drinkers can look healthy in studies, from a lag in French eating habits to the company people keep over a glass789.
We give most weight to these clinicians, and their message is consistent: nobody needs alcohol, and the older allowances of one drink a day, from Pritikin and in Ornish’s guidelines, were tolerated rather than advised5110.
Where they agree
None of these doctors calls alcohol a health food; Goldhamer said so plainly in 2017 and again in 2025, and Pritikin, Chef AJ and Rip Esselstyn all group it with the things a healthy diet leaves out3911112.
Cancer is the risk they name most often: Novick called alcohol a known carcinogen in 2007, Rip Esselstyn’s site cites its listing as a breast carcinogen, and Campbell said Walter Willett’s Harvard cohort data on breast cancer convinced him41314. Goldhamer went furthest in a December 2025 talk, naming red wine among the real causes of the leading diseases alongside tobacco and a poor diet15.
They also agree it works against weight loss: Goldhamer likens its seven calories per gram to fat, Rip Esselstyn reckons a bottle of wine a week adds about ten pounds’ worth of calories a year, and Barnard said in 2024 that it slows the metabolism161718. The liver is a shared worry too, with Goldhamer and Rip Esselstyn both describing how drinking scars it1619.
Where they differ
The doctors part ways on whether a small amount is acceptable, on what explains the red wine studies, on how alcohol adds weight, and on how to think about the people who cannot stop172021.
One drink or none
The older programs allowed a little: in 1982 Pritikin did not object much to a daily drink for healthy people on no medication, and Ornish’s guidelines, as archived in 2011, allowed one serving a day while not encouraging it110. Novick wrote in 2007 that people should not drink, but set a ceiling for those who do: one drink daily for men, half that for women, and advised non-drinkers not to start422. McDougall, Goldhamer and Rogers leave no such room: McDougall holds that no doctor should recommend it, and Rogers advises avoiding alcohol altogether to lower the risk of dementia21523.
What explains the red wine studies
Each skeptic offers a different explanation for why moderate drinkers sometimes look healthier7824. In 1999 Novick traced the French paradox to a time lag after France’s recent rise in animal fat, adding that alcohol deaths there ran three times those in Britain7. Ornish suggested that same year that the social side of drinking with others, not the wine, may be what helps8. Goldhamer argued in 2017 that wine thins the blood like aspirin, trading fewer clotting strokes for more bleeding strokes with no gain in overall survival, and in 2025 said long-lived wine drinkers live long despite the wine249. Barnard pointed in 2014 to a University of Cincinnati study where older adults with early memory loss learned and recalled better after drinking grape juice6.
How it adds weight
Goldhamer treats alcohol as liquid fat because of its calorie count16. McDougall described the mechanism differently in 2022: the body does not turn alcohol into fat but burns it first, leaving stored fat untouched20. Rip Esselstyn’s site makes a similar point, saying alcohol cuts the body’s fat burning by up to 30 percent and also drives appetite toward rich food2526. Ornish, in 1999 and in a 2014 column on triglycerides, counted it with sugar and white flour as a refined carbohydrate2728.
Habit, addiction and personal choice
McDougall, in 2011, judged that most drinkers come to no lasting harm, perhaps nine in ten, but that for a problem drinker the only path that works is to quit completely2930. Doug Lisle agrees that only a small share of drinkers become addicted, while noting in 2024 that about half the alcohol sold in the United States goes to the few percent who are3132. Chef AJ takes the strictest line, running her weight loss program on abstinence from sugar, oil, flour, alcohol and salt because of their calorie density and their pull1133.
Personal habits differ as well: Lisle recalled in 2026 that he and Goldhamer never drank, and that some 20 years earlier he had watched Campbell and Caldwell Esselstyn each order a beer3435. Ann Esselstyn said in 2022 that neither she nor her husband drinks alcohol36.
Changed views
Campbell is the clearest case of a view that moved: in 2023 he said he did not at first accept the link with cancer and used to enjoy beer and wine, before the Harvard data changed his mind3714. In 2025 he added that he had once enjoyed an occasional glass, and spoke of his brother, a heavy wine drinker who later died of cancer38. Lisle, for his part, said in 2026 that most wine drinkers suffer no harm from it, a softer stance than Goldhamer’s3915.
What each expert says
JMJohn McDougall
In a 2011 video McDougall said alcohol works out for most people, but that a doctor’s approval could tip the minority into tragedy, so no doctor should recommend it292. For anyone whose drinking is a problem, he sees stopping entirely as the only answer, as with tobacco30. In 2022 he explained that the body burns alcohol ahead of body fat, which spares the fat stores20.
Campbell said in 2023 that he had doubted the cancer link and liked beer and wine, until Walter Willett’s Harvard data, above all on breast cancer, persuaded him3714. He concluded that people simply do not need alcohol5. In 2025 he described it as a fairly strong risk factor40.
In a 2014 talk on Alzheimer’s, Barnard noted that light drinkers fare slightly better than abstainers and heavy drinkers, then asked whether the grape is the real factor6. In 2020 his advice to a pregnant listener who relaxed with some red wine was to stop drinking entirely41. In 2024 he said alcohol slows the metabolism and suggested a drink without it or water instead18.
In 1999 Ornish put alcohol in the same simple carbohydrate group as sugar and white flour, and his 2014 column on high triglycerides listed it among refined carbohydrates to avoid2728. In the 1999 interview he doubted the red wine story, crediting the social side of drinking8. His program’s guidelines, as archived in 2011, allowed one serving a day without encouraging it10.
Goldhamer said in 2017 that alcohol is not a health food, since grapes supply the resveratrol, and that its blood thinning effect shifts the type of stroke rather than lengthening life324. He calls it liquid fat that also scars the liver16. Speaking in December 2025, he gave red wine the nickname “cancer juice”15.
In a 2026 video Rogers answered yes to whether alcohol causes type 2 diabetes, calling the added risk significant, which he links to fat building up in muscle and other organs4243. In another 2026 lecture he named alcohol and cooking oils as common causes of brain damage and advised avoiding both to lower dementia risk4423.
In a 2007 forum reply Novick wrote that people should not drink, listing cancer, injuries, cirrhosis and possibly bleeding stroke, and saying the heart benefits can be had through diet and lifestyle instead4. For those who drink anyway he set limits and advised non-drinkers not to start22. His 1999 article rejected red wine as the answer to the French paradox7.
A 2023 post on Rip Esselstyn’s PLANTSTRONG site, taken from his Engine 2 book, calls alcoholic drinks empty calories and a toxin to the liver, brain, heart and kidneys4512. It warns that even modest drinking can bring fat into the liver, and cites alcohol’s listing as a breast carcinogen1913.
Chef AJ’s program leaves out alcohol along with sugar, oil, flour and salt, which she sums up as SOFAS11. In 2018 she compared trying to drink in moderation while on the program to asking a sobriety group for help drinking moderately, and said people truly after health would not be drinking4633.
Pritikin told McDougall in 1982 that one drink a day was acceptable for people without symptoms or medication, while calling alcohol a drug rather than a food and noting possible links of beer with colon and breast cancer1. Anyone with high blood pressure, he added, should avoid both alcohol and caffeine47.
Lisle sees beer and wine as concentrated versions of a natural stimulus that can trigger an outsized response in some people21. He has watched former problem drinkers walk past aisles of wine untroubled once the habit has been out of their lives long enough48. He has never drunk himself, yet in 2026 he said most wine drinkers suffer no harm from it3439.
None of these doctors recommends alcohol, and several advise against it outright, so we do not treat wine or beer as part of a healthy plant based diet235. If drinking has become hard to control, or you are pregnant, take medicines or have a health condition, that is a conversation for your own doctor. This page is education, not medical advice.
