You probably
know someone does not drink cow’s milk due to protein sensitivity or concern.
While sensitivities to milk protein exist and should be respected, it’s
important to be aware of the facts about milk as you could needlessly be missing
out on the milk’s many benefits.
A recent
meta-analysis of observational studies and controlled trials dispelled the
common myth that protein found in milk is bad for humans. Researchers concluded
that milk and dairy products are good sources of high-quality protein and that
dairy protein is a source of essential amino acids.
Another
commonly cited problem with milk is lactose.
Lactose
is a sugar in milk that requires the lactase enzyme to break it down. People with lactose intolerance cannot digest lactose
properly. The condition is usually harmless, but its symptoms can be
uncomfortable.
However, in
many cases, the digestive distress some people experience after drinking milk
has nothing to do with Lactose. Instead,
there is a protein found in milk that is often the cause for these
uncomfortable and often embarrassing symptoms.
The Two Forms of Beta-Casein Protein
The protein
in cow’s milk is made up of whey (1 to 2%) and casein (6 to 8%), with the
primary protein known as beta-casein.
Beta-casein
protein comes in two forms, A1 and A2, that affect your body differently. Most
modern-day cow’s milk is a combination of A1 and A2.
Unfortunately,
the A1 protein may cause stomach discomfort.
When A1
protein is digested it produces a peptide called beta-casomorphin-7 (BCM-7). BCM-7 has been linked to stomach discomfort with
similar symptoms to lactose intolerance.
A2 protein is
more comparable to human breast milk, as well as milk from goats, sheep and
buffalo. More natural to the human body, A2 is easily absorbed.
Historically,
cows milk only contained the A2 form of beta-casein. However, over time, a
genetic mutation occurred in cows and resulted in
cows with two types of proteins – A1/A2.
Due to the
genetic mutation that evolved in the cows, A1/A2 milk is here to stay – with
many people unable to enjoy milk’s nutritional properties without frustrating
discomfort.
Fortunately, A2
milk is available. Through selective breeding
a New Zealand company farmers learned to breed cows that only produce the A2 form of Beta
Casein.
A2 Milk has
the4 same nutrition, and creamy, great taste as regular milk and is available
in many stores including Kroger, Walmart, Publix, Safeway, Whole Foods, Sprouts,
Ahold, ShopRite, Wegmans, and Target.
There are
even 100% grass-fed and organic forms of A2 Milk available – just google them!
Since grass –
not grain – is the evolutionary form of food for cows it should be no surprise
that grass fed milk has higher levels of key nutrients. This includes increased levels of Omega 3
Fatty Acids along with conjugated linoleic acid (CLA) which actually helps
reduce bodyfat!.
