Got some milk? Drink it to stay healthy.
But is it really healthy?
Today, we will be exploring...
is milk even good for you?
After breastfeeding age,
mammals usually do not consume milk.
And humans at 1 point did not either.
Only around 11 thousand years ago did humans
discover cow, goat, and sheep milk.
Milk was a staple in our diet,
especially with the milk
ad campaigns in the 90s and
early 2000s pushing for milk consumption.
Although this is true,
you can see a shift in the narrative.
Now looking at the kind of
food guide in 2019,
the kind of food guide was updated,
removing dairy as a food group
and promoting more vegan foods.
In addition, many individuals
have lactose sensitivity,
as you do not have the enzyme lactase
to break down the milk sugar lactose.
Additionally, we commonly see
the signs of lactose intolerance as we
go older because the body lose
the ability to produce lactase.
According to the US National
Library of Medicine,
approximately 65 percent of
the human population cannot digest lactose.
Although this demonstrate a milk is
not necessary for the human diet,
What if you simply just want to
still drink milk regardless?
This video, we'll further
look at current research.
Milk consumption to allow
you to determine that for yourself.
There are some benefits as to why
milk is essential for our diet.
For example, milk can provide
essential amino acids,
vitamins, and minerals.
Essential amino acids are building blocks
for protein which can
only be taken from our diet.
In addition, is high in vitamin B,
A, and C, which are
necessary for bodily processes.
Milk is also a great source of minerals
like calcium, magnesium, and zinc.
One of the main components of milk
is a protein called caesine,
which is a part of providing
antimicrobial properties
and minerals such as calcium,
zinc, iron, and phosphate.
Now we'll be looking at some of
the research diminishing
the cons of the consumption.
Research has shown that the
consumption of milk can
contribute to the development
of prostate cancer.
Prostate cancer is
the third most common type of cancer across
the world and occurs when cells in
the process it rapidly divide and mutate,
grading tumours that can potentially
spread to other parts of the body.
Another factor that can potentially
cause prostate cancer is calcium.
As too much of anything is good for nothing,
Consumption of high concentrations of
calcium can also lead to
the development of prostate cancer.
Cow's milk contains a contributor to prostate cancer
called insulin-like growth factor or ICF,
which is a hormone that promotes
bone and tissue development and growth.
In a human study that was conducted,
purchase events consumed cow's milk.
And it resulted with
an increased concentration of IGF,
increasing the development
of prostate cancer.
Another study also showed that
low fat milk contribute to
the development of the mammary tumours.
These studies conclude that
high concentrations of estrogen and
IGF correlate with prostate cancer
and breast cancer development.
Milk and hormones, ovulation.
Although menarche, the age at which
women were sexual maturity,
is mainly based on genetics.
There are various environmental factors
that can contribute to
reaching menarche an earlier age
than most females.
One of these environmental factors is diet.
Research shows that there's
a significant decrease in age for
the monarchy stage from
16 years to 13 years over time.
One thing that can contribute
to the time, one
reaches menarche is
insulin-like growth factor, IGF.
Synthetic hormones found in cow's milk can be
a contributing factor to
increased IGF concentrations,
thus leading to
accelerating sexual maturation.
Although the study shows that there was
no correlation between intake of dairy fat
consumption from milk and early menarche,
There has been a positive correlation
In the amount of calcium intake
and the chances of having
early menarche. Milk and the environment.
According to an article published
by Cambridge University,
there are crucial increases in
emission of methane gas from dairy cattle.
And this, therefore it leads to
the impact of climate change.
About 0.2% of total carbon footprint
comes from the production of milk.
Specifically, the dairy feed
production. This feed production
contributes to 0.12% of the total emissions.
The production of milk can also
impact the environment through manure,
which can produce greenhouse gas emissions
and feed onto climate change.
Now, you're probably wondering,
how about milk alternatives.
You might have seen nut milk like cashew and
Almond on the shelves or even oat milk
are these alternatives better than cow milk?
As you can see, there are
multiple plant-based milk alternatives
with both pros and cons to each.
Feel free to pause this video and look at
pros and cons for each of
the alternatives more in depth.
When looking at the plant-based alternatives,
In comparison to dairy milk, almond milk,
and rice milk have
the most negative environmental impact.
This is because almond milk
uses the most water use.
While, rice milk has
both high emissions and high water use.
Interestingly, when
you alternative which may make
its way to the shelf soon is lab milk.
This milk is made in
a laboratory without the use of any animals,
but its composition is nearly
identical to cow's milk.
It is made by using a type of yeast to
convert plant sugar into weight and caesine,
the two main cow milk proteins.
While not widely available yet.
Preliminary analysis of this blob milk
had been found to be safe.
It will contain the same
nutrients as cow's milk
once it's fortified and
a similar protein level.
One major benefit is that it will not have
any lactose making a suitable
for lactose intolerant individuals.
Also, the production of this milk will emit
significantly less greenhouse gases
than producing cows milk.
You're probably not thinking so,
is milking and worth it?
Well, that question is hard to answer.
Since it depends on many personal factors,
you have to decide
whether it is right for you.
As mentioned, there are
many dietary benefits. It is
also an integral part of
many foods available in the market,
like yogurt and cheese,
making it quite integrated into
our society. In addition,
is valuable to recognize a milk
also a significant in some cultures,
Meaning it might not be appropriate for
everybody stopped drinking cow's milk.
Finally, there's also
a huge accessibility concern.
Cow's milk
may be the only option
in certain geographical location.
So whether milk is worth it or not
depends on each person and their situation.
