Dairy and Calcium Dangers for Males
Calcium is an incredibly important element in the human body. Virtually
everyone knows that our bone composition and health is dependent on calcium, but
few realize that calcium acts as an "electronic switch" for our neurons and is
critically important to the brain.
Furthermore, Vitamin D and calcium (and therefore dairy) have been shown (at
least in women) to help the body shed fat metabolically and the protein helps
build and maintain muscle as well.  The females in this study lost about 4
pounds of fat and simultaneously gained 4 pounds of muscle, a nice exchange to
say the least.

Calcium is used in so many chemical processes in the body that it would
impossible to go into them all, but it does, for example, help with periodontal
(gum) disease  and I have mentioned elsewhere, in my link on High Blood
Pressure and Erections, how it forms a trinity of elements with sodium and
potassium to help avoid hypertension.
All of that said, it is definitely possible for men to have "too much of a good thing"
and calcium is no exception. Both calcium and dairy can easily lead to very dangerous situations for males,
including cancers, and so a few cautions are in order:
1. Prostate Cancer and Calcium. My Prostate Cancer link covers the study that
shows that overly high calcium intakes can put males at greater risk for
2. Generalized Cancer Promotion. Casein, the chief protein in milk
and dairy is a known increaser of IGF-1. Many bodybuilders are IGF-1 enthusiasts, because
it can add in hypertrophy (muscle building). However, IGF-1 is controversial at best
because much research shows that in the right conditions it can promote cancer, especially as we age. I cover this in detail in my
link on IGF-1.
3. Liver Cancer. Many people have heard about the bestselling book
The China Study and the work of T. Colin Campbell. What is not as well known is that
his initial claim to
fame in the research labs was examining the remarkable ability of casein
to promote liver cancer under certain conditions in laboratory animals. If casein
was high enough in the diet, liver cancer rates were dramatically increased. 
Again, if you get enough dairy in your diet, there is good evidence it could make
you vulnerable to this nasty cancer.
4. Inflammation. Casein is also a known promoter of inflammation in
many cases and
it is even used in animal studies to do the same.  Another interesting
example is how small amounts of dark chocolate have been found to lower
inflammation levels but additional amounts yield no net benefit. The
reason? It is likely the casein in the chocolate overcoming cacao's
excellent benefits. (See my link on
The Benefits of Dark Chocolate for
So, again, moderation is the key when it comes to calcium. I personally try
not to consume more than 1-2 times the RDA for calcium. As far as milk and
dairy, I avoid them. I will occasionally consume nonfat milk for a protein
boost, but keep it to one serving only.
