Added sugar is the single worst ingredient in the modern diet. It can have harmful effects on metabolism and contribute to all sorts of diseases.
Here are some reasons why you should avoid added sugar like the plague:
Added Sugar Contains No Essential Nutrients and is Bad for Your Teeth. Added sugars (like sucrose and high fructose corn syrup) contain a whole bunch of calories with NO essential nutrients.
Sugar is also very bad for the teeth, because it provides easily digestible energy for the bad bacteria in the mouth
Added Sugar is High in Fructose, Which Can Overload Your Liver. To understand what is so bad about sugar, then you need to understand what it is made of.
Before sugar enters the bloodstream from the digestive tract, it is broken down into two simple sugars… glucose and fructose.
The thing is that it can only be metabolized by the liver in any significant amounts. This is not a problem if we eat a little bit (such as from fruit) or we just finished an exercise session. In this case, the fructose will be turned into glycogen and stored in the liver until we need it.
However, if the liver is full of glycogen (much more common), eating a lot of fructose overloads the liver, forcing it to turn the fructose into fat.
When repeatedly eating large amounts of sugar, this process can lead to fatty liver and all sorts of serious problems.
It is almost impossible to overeat fructose by eating fruit.
Because it causes Massive Dopamine Release in The Brain, Sugar is Highly Addictive. Sugar can be addictive for a lot of people. Like abusive drugs, sugar causes a release of dopamine in the reward center of the brain.
The problem with sugar and many junk foods is that they can cause massive dopamine release.
For this reason, people who have a susceptibility to addiction can become strongly addicted to sugar and other junk foods.
