Processed foods are bad.
Processed foods are bad.
They are the main reason why people all
over the world are getting fat and sick.
How do we know?
Every time a population adopts a
“Western” diet high in processed foods, they get sick.
It happens within a few years. Their
genes don’t change, their food does.
Real vs Processed Food
The word “processed” often causes some
confusion, so let me clarify what I mean.
Obviously, most foods we eat are
processed in some way. Apples are cut from trees, ground beef has been ground
in a machine and butter is cream that has been separated from the milk and
churned.
But there is a difference between
mechanical processing and chemical processing.
If it’s a single ingredient food with no
added chemicals, then it doesn’t matter if it’s been ground or put into a jar.
It’s still real food.
However… foods that have been chemically
processed and made solely from refined ingredients and artificial substances,
are what is generally known as “processed food.”
Here are 9 ways that processed foods are
bad for your health.
1. Processed Foods Are Usually High in
Sugar and High Fructose Corn Syrup
Sugar cubes
Processed foods are usually loaded with
added sugar… or its evil twin, High Fructose Corn Syrup.
It is well known that sugar, when
consumed in excess, is seriously harmful.
As we all know, sugar is “empty” calories
– it has no essential nutrients, but a large amount of energy.
But empty calories are really just the
tip of the iceberg when it comes to the harmful effects of sugar…
Many studies show that sugar can have
devastating effects on metabolism that go way beyond its calorie content .
It can lead to insulin resistance, high triglycerides, increased levels of the harmful cholesterol and increased fat accumulation in the liver and abdominal cavity.
Not surprisingly, sugar consumption is
strongly associated with some of the world’s leading killers… including heart
disease, diabetes, obesity and cancer.
Most people aren’t putting massive
amounts of sugar in their coffee or on top of their cereal, they’re getting it
from processed foods and sugar-sweetened beverages.
2. Processed Foods Are “Hyper Rewarding”
and Lead to Overconsumption
We all want to eat good food. That’s just
human nature.
Evolution provided us with taste buds
that are supposed to help us navigate the natural food environment.
Our appetite gravitates towards foods
that are sweet, salty and fatty, because we know such foods contain energy and
nutrients that we need for survival.
Obviously, if a food manufacturer wants
to succeed and get people to buy their product, it has to taste good.
But today, the competition is fierce.
There are many different food manufacturers, all competing with each other.
For this reason, massive resources are
spent on making foods as desirable as possible.
Many processed foods have been engineered
to be so incredibly “rewarding” to the brain, that they overpower anything we
might have come across in nature.
We have complicated mechanisms in our
bodies and brains that are supposed to regulate energy balance (how much we eat
and how much we burn) – which, until very recently in evolutionary history,
worked to keep us at a healthy weight.
There is quite a lot of evidence that the
reward value of foods can bypass the innate defense mechanism and make us start
eating much more than we need, so much that it starts to compromise our health
(9, 10).
This is also known as the “food reward
hypothesis of obesity.”
The truth is, processed foods are so
incredibly rewarding to our brains that they affect our thoughts and behavior,
making us eat more and more until eventually we become sick.
Good food is good, but foods that are
engineered to be hyper rewarding, effectively short circuiting our innate
brakes against overconsumption, are NOT good.
3. Processed Foods Contain All Sorts of
Artificial Ingredients
If you look at the ingredients label for
a processed, packaged food, chances are that you won’t have a clue what some of
the ingredients are.
That’s because many of the ingredients in
there aren’t actual food… they are artificial chemicals that are added for
various purposes.
This is an example of a processed food,
an Atkins Advantage bar, which is actually marketed as a low-carb friendly
health food.
I don’t know what this is, but it most
certainly isn’t food.
Highly processed foods often contain:
Preservatives: Chemicals that prevent the
food from rotting.
Colorants: Chemicals that are used to
give the food a specific color.
Flavor: Chemicals that give the food a
particular flavor.
Texturants: Chemicals that give a
particular texture.
Keep in mind that processed foods can
contain dozens of additional chemicals that aren’t even listed on the label.
For example, “artificial flavor” is a
proprietary blend. Manufacturers don’t have to disclose exactly what it means
and it is usually a combination of chemicals.
For this reason, if you see “artificial
flavor” on an ingredients list, it could mean that there are 10 or more
additional chemicals that are blended in to give a specific flavor.
Of course, most of these chemicals have
allegedly been tested for safety. But given that the regulatory authorities
still think that sugar and vegetable oils are safe, I personally take their
“stamp of approval” with a grain of salt.
4. Many People Can Literally Become
Addicted to Processed Junk Foods
The “hyper rewarding” nature of processed
foods can have serious consequences for some people.
Some people can literally become addicted
to this stuff and completely lose control over their consumption.
Although food addiction is something that
most people don’t know about, I am personally convinced that it is a huge
problem in society today.
It is the main reason why some people
just can’t stop eating these foods, no matter how hard they try.
They’ve had their brain biochemistry
hijacked by the intense dopamine release that occurs in the brain when they eat
these foods.
This is actually supported by many
studies. Sugar and highly rewarding junk foods activate the same areas in the
brain as drugs of abuse like cocaine.
5. Processed Foods Are Often High in
Refined Carbohydrates
There is a lot of controversy regarding
carbohydrates in the diet.
Some people think that the majority of
our energy intake should be from carbs, while others think they should be
avoided like the plague.
But one thing that almost everyone agrees
on, is that carbohydrates from whole foods are much better than refined
carbohydrates.
Processed foods are often high in carbs,
but it is usually the refined variety.
One of the main problems is that refined,
“simple” carbohydrates are quickly broken down in the digestive tract, leading
to rapid spikes in blood sugar and insulin levels.
This can lead to carb cravings a few
hours later when blood sugar levels go down again. This phenomenon is also
called the “blood sugar roller coaster” – which many people who have been on a
high-carb diet can relate to.
Not surprisingly, eating a lot of refined
carbohydrates is associated with negative health effects and many chronic
diseases.
Do NOT be fooled by labels like “whole
grains” that are often plastered on processed food packages, including
breakfast cereals.
These are usually whole grains that have
been pulverized into very fine flour and are just as harmful as their refined
counterparts.
If you’re going to eat carbs, get them
from whole, single ingredient foods, not processed junk foods.
6. Most Processed Foods Are Low in
Nutrients
Processed foods are extremely low in
essential nutrients compared to whole, unprocessed foods.
In some cases, synthetic vitamins and
minerals are added to the foods to compensate for what was lost during
processing.
However, synthetic nutrients are NOT a
good replacement for the nutrients found in whole foods.
Also, let’s not forget that real foods
contain much more than just the standard vitamins and minerals that we’re all
familiar with.
Real foods… like plants and animals, contain
thousands of other trace nutrients that science is just beginning to grasp.
Maybe one day we will invent a chemical
blend that can replace all these nutrients, but until that happens… the only
way to get them in your diet is to eat whole, unprocessed foods.
The more you eat of processed foods, the
less you will get of vitamins, minerals, antioxidants and various trace
nutrients.
7. Processed Foods Tend to be Low in
Fiber
Fiber, especially soluble, fermentable
fiber, has various benefits.
One of the main ones is that it functions
as a prebiotic, feeding the friendly bacteria in the intestine.
There is also evidence that fiber can
slow down the absorption of carbohydrates and help us feel more satisfied with
fewer calories.
Soluble fiber can also help treat many
cases of constipation, which is a very common problem today.
The fiber that is found naturally in
foods is often lost during processing, or intentionally removed. Therefore,
most processed foods are very low in fiber.
8. It Requires Less Energy and Time to
Digest Processed Foods
Food manufacturers want their processed
food products to have a long shelf life.
They also want each batch of the product
to have a similar consistency and they want their foods to be easily consumed.
Given the way foods are processed, they
are often very easy to chew and swallow. Sometimes, it’s almost as if they melt
in your mouth.
Most of the fiber has been taken out and
the ingredients are refined, isolated nutrients that don’t resemble the whole
foods they came from.
One consequence of this is that it takes
less energy to eat and digest processed foods.
We can eat more of them in a shorter
amount of time (more calories in) and we also burn less energy (fewer calories
out) digesting them than we would if they were unprocessed, whole foods.
One study in 17 healthy men and women
compared the difference in energy expenditure after consuming a processed vs a
whole foods-based meal (21).
They ate a sandwich, either with
multi-grain bread and cheddar cheese (whole foods) or with white bread and
processed cheese (processed foods).
It turned out that they burned twice as
many calories digesting the unprocessed meal.
The Thermic Effect of Food (TEF) is a
measure of how much different foods stimulate energy expenditure after eating.
It totals about 10% of total energy expenditure (metabolic rate) in the average
person.
According to this study, people who eat
processed food will cut their TEF in half, effectively reducing the amount of
calories they burn throughout the day.
9. Processed Foods Are Often High in
Trans Fats or Processed Vegetable Oils
Processed foods are often high in
unhealthy fats.
They usually contain cheap fats, refined
seed- and vegetable oils (like soybean oil) that are often hydrogenated… which
turns them into trans fats.
Vegetable oils are extremely unhealthy
and most people are eating way too much of them already.
These fats contain excessive amounts of
Omega-6 fatty acids, which can drive oxidation and inflammation in the body.
Several studies show that when people eat
more of these oils, they have a significantly increased risk of heart disease,
which is the most common cause of death in Western countries today.
If the fats are hydrogenated, that makes
them even worse. Hydrogenated (trans) fats are among the nastiest, unhealthiest
substances you can put into your body.
The best way to avoid seed oils and trans
fats is to avoid processed foods. Eat real fats like butter, coconut oil and
olive oil instead.
