heavy drinking may be the most common cause of potentially reversible hypertension in developed societies (Fifth Report 1993)...the preponderance of evidence suggests that moderate drinking is associated with lower risk of ischemic strokes (Van Gign et al. 1993).... A common manifestation of CAD [coronary artery disease] is angina pectoris,...Alcohol was widely presumed to alleviate angina by dilating the coronary blood vessels..... former drinkers had higher age-adjusted CAD and overall CVD mortality
risk than lifelong abstainers, but the difference disappeared when
adjusted for other traits. Among current drinkers, lighter drinkers had
the lowest risk for both total CVD (i.e., cardiovascular diseases [CVDs]) deaths and CAD deaths

Researchers have also suggested that red wine, in particular, might protect the heart, thanks to the antioxidants it contains. ...hard cider contains antioxidants like polyphenols and vitamin C
from its apple base, which can help fight free radicals, similar to or
even more than green tea or orange juice in some studies,... the body processes ethanol in stages, converting it first to toxic
acetaldehyde, then to less harmful acetate (acetic acid), which is
eventually broken down into carbon dioxide and water, though a small
amount is excreted directly; Acetaldehyde occurs naturally in coffee,
bread, and ripe fruit, and is produced by plants as part of their
normal metabolism. It is also produced by oxidation of ethanol and is
popularly believed to be a cause of hangovers from alcohol consumption...Acetaldehyde exposure from
coffee is significantly lower
(orders of magnitude) than the amount of acetaldehyde produced in the
body during the metabolism of even a small amount of alcohol...Polyphenols in red wine and coffee may stimulate Acetaldehyde [AcAld] formation by acting as pro-oxidants in the presence of Heme/Mb/Meat....after the consumption of a red meat-rich diet with red wine, the fecal
AcAld level significantly increased as compared to the levels associated
with a diet of fish + wine, or red meat without alcohol.

EtOH is the chemical abbreviation for ethanol,...Regarding colorectal cancer, a 13-fold greater amount of OH radicals is
reportedly generated in human feces after a high meat and high fat diet
with few vegetables, as compared to that after low meat and low fat diet
with sufficient vegetables [45]. Persistent colonic ethanol, which is maintained for several hours after drinking [46, 47], may react with the OH radical generated in the colon to form AcAld.
browned fried foods generate acetaldehyde and other toxic aldehydes
from the breakdown of fats (lipids) and sugars at high heat, which are
reactive compounds linked to inflammation, cardiovascular disease, and
cancer; these aldehydes get absorbed by the food and can be consumed,
making oil choice and cooking methods crucial for reducing risk
Lead author, PhD student
Chengyi Ding (UCL Institute of Epidemiology & Health Care), said:
“Our findings suggest that people with cardiovascular disease may not
need to stop drinking in order to prevent additional heart attacks,
strokes or angina, but that they may wish to consider lowering their
weekly alcohol intake...."
Nearly half of U.S. adults have some form of cardiovascular disease
(CVD), with recent data showing around 48-49% affected, largely driven
by high blood pressure, while globally, CVD causes about 32% of all
deaths, with heart attack and stroke being the biggest killers. In the
U.S., approximately 121.5 million adults deal with CVD, a figure expecting to rise to 60% by 2050...
the supposed benefits of alcohol consumption may actually be attributed
to other lifestyle factors that are common among light to moderate
drinkers....Consistent with earlier studies, investigators found that light to
moderate drinkers had the lowest heart disease risk, followed by people
who abstained from drinking....The study included 371,463 adults—with an average age of 57 years and an
average alcohol consumption of 9.2 drinks per week—who were
participants in the UK Biobank, a large-scale biomedical database and
research resource containing in-depth genetic and health information.... less than six pints of
medium-strength beer or just over one bottle of wine – could potentially
confer some protective benefits.

The studies, however, had some major flaws, including that people’s
drinking was generally categorized only by their current behavior.
“A
lot of people who don’t currently drink are people who used to drink
heavily, or who have health problems that led them to quit,” said Keith Humphreys,
PhD, a professor of psychiatry and behavioral sciences and the Esther
Ting Memorial Professor. “That skews the data, making moderate drinkers
look healthier by comparison.”
“Any amount of alcohol increases your risk of certain cancers,
especially those along the digestive tract – mouth, throat, esophagus,
colon,” Humphreys said. “And for women, alcohol increases the risk of
breast cancer.”
Alcohol is metabolized to AcAld by alcohol dehydrogenase (ADH) enzymes,
and then to acetic acid by aldehyde dehydrogenase (ALDH). High
incidences of oral, esophageal, stomach and colon cancers have been
observed in ALDH-deficient subjects..., the results suggest that the AcAld enhancing effect observed in the model reaction could occur in vivo by the combination of red meat and wine....However, heavy drinkers of wine have high incidences of gastric cancer,
as revealed by epidemiological studies in France, Portugal and Paraguay [17–19].
Prospective studies in large populations demonstrated that persons who
preferred wine were more likely to develop colon cancer [20, 21].
Processed meats such as sausage, ham and salami are suspected to be
higher risk factors for both gastric and colon cancers than red meat [2–4].
Other epidemiological studies suggested that the co-consumption of
alcohol and red meat synergistically increases the colon cancer risk [22, 23].
Weird how only ONE news channel for local news reports this?
“In the past 10 years or so, in my practice, I’ve added alcohol to
the list of substances I recommend my patients either reduce or
eliminate from their diet,” said Randall Stafford, MD, PhD, a professor of medicine and director of the Program on Prevention Outcomes and Practices.
Stafford
and his colleagues said the choice to tip back a beer or forgo alcohol –
like many lifestyle decisions – should involve weighing the risks and
benefits of your behaviors. But they think the public should be made
more aware of those risks, which include an increased risk of cancer
from drinking moderate amounts of alcohol.... ethanol, the type of alcohol found in beverages, metabolizes into a
compound called acetaldehyde, which damages DNA and other cellular
components. When acetaldehyde builds up in the body, it can damage cells
throughout the digestive system and beyond....
Because acetaldehyde accumulates more quickly in people with the
ALDH2 variant, they are at an increased risk of alcohol-related
diseases, including cancer and heart disease, even at lower levels of
alcohol consumption. This specific genetic variant is overwhelmingly concentrated in
populations of East Asian descent, where frequencies can be as high as
40-50%...While about 40% of the South American Indian populations (Atacameños,
Mapuche, Shuara) were ALSO found to be deficient in aldehyde dehydrogenase
isozyme I (ALDH2 or E2)
“If you have this mutation, one drink can be
the equivalent of four or five for someone else in terms of how much
acetaldehyde accumulates,” he said. “For those individuals, the safest
choice is to avoid alcohol entirely.”

Alcohol Industry is spreading fake medical news? NO alcohol is good for the heart
The World Health Organization has made it clear that there is no safe level of alcohol consumption, mainly due to the risk of cancer increasing from low levels of drinking, as Professor Britton mentions in this film
TODAY show actually covered the 2023 Massachusetts hospital study showing low alcohol reduces heart clot risk...
But when you take into account OTHER factors like excercise, diet and smoking - then alcohol is NOT healthy at all - at any dose...
Red wine drinkers probably have healthier OTHER life style factors.... (not smoking, not obese, exercise and better diet)...
Researchers at Massachusetts General Hospital say they have found that drinking alcohol in light to moderate quantities can actually be good for heart health due to the impact it has on the brain’s stress systems.

lowering alcohol intake to mild to moderate level was
associated with a 23% reduction in the risk of major adverse
cardiovascular events compared with sustained heavy drinking. The most
substantial risk reduction was observed in the outcomes of angina and
ischemic stroke.
Meaning
Findings of this study provide crucial evidence of the
cardiovascular benefits of reducing alcohol consumption in people who
drink heavily.
https://www.ahajournals.org/doi/10.1161/CIR.0000000000001341
The available evidence suggests no risk to possible risk reduction when
alcohol is consumed in low amounts (such as no more than 1 to 2 drinks a
day) in regard to coronary artery disease, stroke, sudden death, and
possibly heart failure.
