Are oils healthy? Are oils bad for you? Are we designed to eat oils? Are oils necessary in our diet? In this video, I dive into the world of oils and discuss some of …
It seems as if oils have become an integral part of our diet
It's on the ingredient list of many
products in our grocery stores,
it's in large percentage of the recipes
you'll find online or in recipe books,
and it comes with almost every dish in restaurants.
There's no doubt that oils contribute to the flavor and texture of our food
While most people know it's not the best to consume oils in large amounts,
they never stop to question whether we are even designed to consume oils
or how it affects our health and pretty much every system in our body
So today we're going to talk about that and cover
some of the unfavorable health effects that are caused by oils.
Let's begin with rancid fat
What foods can become rancid?
So any food that contains fat is at risk of becoming rancid
but the most problematic foods are any type of cooking oil
and unsaturated oils are even more unstable because of their chemical structure
Now, what's the problem with rancid fat?
So eating rancid fat may not make you sick in the short term
but consuming rancid fat over time, over and over again, can negatively affect your health
and here's how
So fats can become rented through the exposure to heat,
light, irradiation, and oxidation.
The moment fats are
exposed to air, they begin the process of oxidation
And oxidation results in free radical production in the body
Now, free radicals create damage in our cells and our DNA
There are lots of issues that arise because of this process
but to name a few, the first one is that
when a cell's DNA changes, the cell
becomes mutated
which can increase the risk to develop
cancer and other inflammatory diseases
Also with unsaturated oils, including olive oil,
heating it to high temperatures will cause the oil to develop compounds
that have been found
to have carcinogenic properties
Another effect that this process has is
that it speeds up the aging process
The oxidation process leads to cell damage
including skin cells and that translates
into moles and age spots
showing up on our skin and even wrinkles
And the last issue which I felt is important to mention,
is the damage to our brain cells
Studies on animals showed that
when they were fed with oxidized vegetable oils,
it showed they can cause damage to brain cells
and lead to inflammation
and other brain-related diseases
Although we can reduce the amount of
free radicals in the body
by consuming lots of fruits and
vegetables that contain antioxidants,
it is always better to just eliminate the root cause in the first place
Next up our cardiovascular system
So the cardiovascular system refers to:
the heart, the blood vessels and the blood itself
Now, what happens when we consume oil?
So within hours of ingesting oils,
the blood becomes thick which slows the flow of blood
and the arteries stiffen which impair
the ability to widen and constrict
and here's a great video that shows this
very well
This video is from Dr Roy Swank of
Oregon state university
This is the intestine of a
rabbit under a microscope before
and after a bolus of oil was placed
into its mouth
You can see that the blood is flowing smoothly, consistently, a good flow
Now within minutes, the blood turns into sludge like 20 50 oil on a cold day
You can see the blood flow even stopped
in the capillaries and the tissue
turned blue indicating hypoxia thus
showing how significantly oil reduces blood flow in the intestine after just one dose
The blood takes 10 hours to resume normal blood flow
We may not quite understand the
mechanism but the result
is that oil and fat consumption appears
quite obvious from this microscopic
video film
Hardening of the arteries occurs when
fats build up in the walls of the arteries
Over time these plaques can narrow or
completely block the arteries
and cause a lot of issues in the body
because of the restricted flow of blood,
oxygen, and nutrients that are supposed
to move through the vessels
In our blood vessels, we have something called endothelial cells
These cells cover the inner lining of the blood vessels
One of their functions is to ensure proper blood flow, to and from the heart
and they basically maintain the proper dilation and constriction of the blood vessels
and studies found a significant decrease
in endothelial function
that appears within 3 hours
after a meal that contained oil,
no matter the type of oil that was
All kinds of oils, including olive oil, were found to contribute to the damage of the arteries
and the progression of heart disease
Next, is our digestive system
Oil tends to interfere with digestion, especially when consumed with carb or protein-rich foods,
unlike natural fats that we're designed to eat in nature
what happens is that oils block the
digestive enzymes
and inhibit proper digestion in the stomach
they also slow down the digestion process
and as a result food spends more time in your stomach
which can cause bloating, diarrhea, stomach pain, and more.
You're very likely to feel sleepy and
heavy after a meal
because your body has to work harder to
digest and eliminate the food that just got in
And last but not least, let's talk about the nutritional value of oil
So oil is stripped away from almost all of the vitamins and minerals,
leaving us with 100% fat.
There are no nutritional benefits in oils,
unlike the package of nutrients that
come with other healthy fats
like nuts, seeds, and avocados for example.
Oils are empty calories and it is very easy to go over your daily calorie intake with them
since it's the most calorie dense food
available to us
In just one tablespoon of oil you can
get around 120 calories
so if you take a baked potato for
example it has around 160 calories
with close to zero percent fat
While the same amount of french fries which are fried in oil,
have around 500 calories and between 30 to 45% fat
Frying with oil has over 3 times the amount of calories
Just by getting rid of the oils in your diet, you're already likely to lose weight
Of course, it depends on other things in
your diet as well
but I personally know people who took
just this step,
just took out the oils from their diet,
and they lost 5 to 10 pounds of their weight without much effort
For most people, it might not necessarily
be a life or death situation,
but I thought it was worth mentioning
because visceral fat can be the beginning of many health problems
and for those of you who are interested
in losing the last few stubborn pounds
I thought this is a great start
And now for the common question:
Is it okay to eat oils in small amounts?
So usually the answer to this type of question is that
if you eat things in moderation and stick to mostly good foods in your diet
then everything should be fine
but this is not so true in the case of oil
It all depends on how healthy you want
to be
and how you want your body to function
In the case of oil, even the consumption of small amounts accumulates and builds up in our body
and overtime damages our cells and many systems inside, the moment it enters
There's really no reason to consume oils
because we can get all the essential
fatty acids and more nutrients from
other whole and fresh fat sources
