Just like refined sugar, it makes you fat in the long run because the liver converts excess
fructose into fat and stores it as a reserve.
There is some evidence that the body finds it easier to make that second choice: turning
the fructose into fat.
We know the liver will turn some of
this fructose into fat and if the fructose is delivered quickly enough (say in liquid form as sugar water), it likely to cause insulin resistance in the liver, which in turn might cause systemic insulin resistance.
Not exact matches
When we consume too much
fructose the liver converts it
into fat.
It is an interesting one, Sarah's position is in line with David Gillespi and focuses on how the body turns
fructose straight
into fat (as well as the issues it has w refined sugars) and is based on how our bodies used it back in caveman times — interesting ideas.
Fructose is processed by your liver
into triglycerides or stored as
fat.
Loading your diet with fruits isn't recommended as this can impact your health (excess
fructose can cause high blood sugar & will get transformed
into fat).
Since our bodies are unable to use this
fructose isomer for energy it is transformed
into triglycerides (
fat).
If the liver is overloaded with
fructose it's then turned
into fat and stored.
Most processed sweet things have high
fructose corn syrup in them, which the liver turns
into fat and stores (usually on your tummy or hips!)
By preparing more of your own meals, you can control the ingredients that make their way
into your foods (many of the ingredients used in restaurant meals and pre-made meals are highly processed — think trans
fats, high
fructose corn syrup and low quality meats).
This reflects the fact that the liver makes lots of
fat from the
fructose component of sucrose while choline deficiency prevents the liver from sending that
fat out
into the blood.
When you eat a lot of added sugar, the liver gets overloaded with
fructose and is forced to turn it
into fat (4).
In addition,
fructose is metabolized
into fat far more rapidly.
The resulting equation is simple:
fructose (found in most processed foods) and dietary carbohydrates (sugars and grains, which break down
into sugar) lead to excess body
fat, obesity and related health issues.
While glucose is absorbed directly
into the blood from the digestive tract, to be used as energy by our cells,
fructose must first be processed by the liver, where is shunted
into the metabolic pathway that leads to
fat synthesis.
With high consumption of refined sugar, the liver gets burdened with
fructose and ends up turning it all
into fat (14).
If this sugar is in the form of
fructose, it gets shuttled to our liver where it will be metabolized, but if our liver is overloaded, it can turn those incoming sugars
into triglycerides, which is essentially
fat in the blood.3, 4, 5 This is why sugar is now being considered by some scientists as a chronic liver toxin, potentially leading to non-alcoholic fatty liver disease (NAFLD) and metabolic diseases.6, 7
Once the liver starts getting overloaded,
fructose will be metabolized
into fat rather than liver glycogen, which can lead to obesity, the collection of
fat around vital organs and insulin resistance.
Taubes has also delved deep
into the science of
fructose, and his new book, Why We Get
Fat: and What to Do About it, explains why a low - carb diet is the path to optimal health.
In the process, the liver will convert excess
fructose to
fat, which is stored in the liver and also released
into the bloodstream.
The liver starts making
fats from the
fructose and sends them off
into the blood stream as «triclycerides» or
fat.
High
fructose corn syrup is basically sugar that your body finds almost impossible to process, therefore turning it
into fat.
In the liver,
fructose goes through conversion
into glucose or (more frequently),
fructose is stored (often as
fat).
This result is compatible with Stephan's views because carb and
fat together are more rewarding than either alone, and with my views because carb -
fat combinations can be highly toxic — for instance, a
fructose - PUFA combination is more toxic than either alone; or carbs feed gut pathogens while
fats carry their toxins
into the body.
When the limited glycogen stores are full, the excess
fructose is changed directly
into liver
fat through de novo lipogenesis.
Most folks locked
into the «standard American diet» take in high calories from non-
fat or low
fat foods containing heavy amounts of sugar or high
fructose corn syrup used even in processed or fast foods that are not sweet tooth satisfying.
Instead, these refined
fructose sweeteners are primarily converted
into triglycerides (
fat in the bloodstream) and adipose tissue (body
fat).
In
fat cells, it stimulates the synthesis of fatty acids from other fuels (e.g. glucose and
fructose), and prevents the breakdown of
fats into fatty acids.
