Alcohol: Pros and Cons
Alcohol - is it good for you or bad for you? Does it protect your heart or
endanger it? Well, the answer to those questions require more than just a
simple "yes" or "no". The overwhelming consensus is that alcohol,
one or two drinks per day, is heart-protective. And since heart disease is
the number one killer of us males, this has often put alcohol center stage as a
healthy addition to a fit lifestyle.
How does it do its cardiovascular magic? Alcohol, again in doses of one or two drinks per day,
HDL levels,  which is cardioprotective and
can even stimulate erection-producing
Nitric Oxide. It also seems to stabilize arterial plaques and somewhat reduce their
formation as well.  Alcohol, in moderation of course, also thins the blood and reduces clotting
and, of course, it is clotting that can contribute to MI's (heart attacks).
This also helps explain how several studies have also found that moderate alchohol
consumption reduces the risk
for stroke which are the results of clots. 
Alcohol has also other good properties as well. Red wine, for example, has been found to
be significantly protective of Prostate Cancer. A 2010 study found
that moderate drinking was able to significantly protect the brain. 
Other cross-gender studies have shown the same thing.  
So moderate alcohol consumption is a no-brainer, right? As is often the
case, the story is much more complex.
Alcohol produces toxins and carcinogens, increases the risk for certain cancers
and lowers levels of many critical nutrients and antioxidants.
The truth is that there is an alternative: a
Low Fat Diet. A
Low Fat Diet, such as the Ornish Diet, is so heart protective that it actually reverses
arterial plaque. As I have pointed out, cultures and people that have maintained
cholesterol below 150 for a substantial portion of their life
have virtually no
heart disease. In addition,
Low Fat Diet also looks very protective against
prostate cancer as well.
Do you know the foods and drinks that increase erection-boosting
Nitric Oxide? Check out the
Peak Erectile Strength Diet where I show
you how to dramatically and naturally improve your erectile strength.
The bottom line is that you have two reasonable ways to go: 1) a
Mediterranean Diet with moderate alcohol consumption and 2) a Low Fat Diet
where alcohol consumption is not necessary and provides little additional benefit. Of course,
the advantage to the latter is avoidance of the following very negative aspects
HANGOVER: What about if you go overboard and drink more than 1-2
drinks? It turns out that there is some research showing which foods are
actual Legitimate Hangover Aids and Cures.
Seven Dangers of Alcohol
Again, this is not an issue for moderate drinkers.Lung, Prostate and Liver Cancer.
The extra estrogen burden of alcohol is apparently hard on the prostate
according to one study.  The same study found that it is increases risks for
the two "Big L" cancers, liver and lung, as well. DNA/Cellular Damage
Acetaldehyde, a metabolite that occurs in the body when alcohol is broken down,
causes Fetal Alchohol Syndrome symptoms in one study of rat embryos.  Scientists discovered that it could cause "histologically characterized
by marked cellular death" and "malformations" similar to those produced in Fetal
Alcohol syndrome. There is also evidence that acetaldehyde can damage DNA.
Glutathione and Vitamin C. Two of the body's key
antioxidants are glutathione and Vitamin C. Alcohol consumption lowers levels
of both of these key protective agents. In the case of glutathione, this occurs
because it binds to carcinogens and toxins produced by alcohol in order to
protect the body. Alcohol also leads to increased urinary excretion of Vitamin
- Weight Gain. Alcohol adds calories quickly. One 12 oz. beer is about 120 calories and 6
oz of wine is about the same. Consumption of more than 1 or 2 drinks per day will
lead most people to put on weight, which increases one's risk of heart disease,
increases estrogen and many other nasty things for males that I
outline here. And
keep in mind that alcohol adds all these calories with relatively little nutritional
value. The one exception to this is probably red wine, which is loaded with
strong antioxidant phytochemcials such as resveretrol.
- Testosterone. Alcohol can deplete zinc slightly and a zinc
deficiency can lead to lower testosterone levels. However, I know of no study
that shows moderate drinking leads to lower testosterone levels. See my
Testosterone and Alcohol for more details. (But
zinc is definitely a
Powerful Sex Mineral.
One pathway that our livers use to detoxify alcohol is called the cytochrome
P450 enzymatic system. Unfortunately, the P450 system is used for other
important functions including the breakdown of estrogen. This means that
consumption of alchohol results in increased estrogen, which, for males, can be
very bad news.
The aging process generally leaves us guys with increasing amounts of estrogen anyway: the last thing we need is
more. Estrogen is linked, among other things, with significant
prostate cancer risk. Again, this does not seem to be a significant issue for
male, moderate drinkers. (CAUTION: This is a potential issue for females,
however, as even moderate drinking has been shown to increase breast cancer
- GI Cancers. There is strong evidence
that alcohol increases cancer risk everywhere it "touches", i.e. in the mouth, throat/esophagus,
colon and rectum in addition to the liver. One study  found after
studying Italians, who are known for drinking significant amounts of wine, that
"this study thus indicates that in the Italian population characterized by frequent
wine consumption, wine is the beverage most strongly related to the risk of laryngeal
cancer". Many studies have shown that alchohol consumption leads to increased risk
of intestinal cancer, some at levels as low as one or two drinks per day.  One
key pathway by
which alcohol can stimulate cancer is through the hotly researched EMT pathway.
This is bad news indeed, because it means that alcohol can literally turn on
cancer cells and accelerate their progression.
- Skin Cancer. Several studies have shown an increased risk of basal cell
carcinoma, a type of skin cancer, with alcohol consumption. 
Alcohol, at least beyond some threshhold which is probably around three drinks
for most individuals, increases blood pressure.
