What does Sugar do to the Body? First, a little about Glucose, Lactose, Sucrose
Before we answer the question, what does sugar do to the body, let’s talk about the different types of sugar: glucose, lactose, and sucrose. Glucose is a simple form of sugar that is primarily used for energy in the body. Lactose, found in items like cheese, milk, yogurt, is a more complex sugar made up of glucose and galactose. Sucrose is also a complex sugar made of 50% glucose and 50% fructose. We will spend our time discussing fructose as it has the most detrimental effects on the body.
What does sugar do when it enters the body:
When sugar enters the body it splits into two parts: fructose and glucose. These elements make their way to the liver, where, once inside, must be dealt quickly. Glucose, which is found is a wide arrange of naturally occurring foods items, it is used immediately for energy or stored for later use much like a spare battery.

What does sugar do to the brain?
The liver is not alone in its unusual response to fructose; the brain has an unnerving reaction as well. Here is how the brain works when it comes into contact with fructose:- When we see a cue, an ice cream cone, for example, our brains releases dopamine – a hormone that gives a burst of quick energy and causes good feelings to flow through the body. This causes a spike in the blood sugar which can yield a temporary sense of alertness and focus. The fructose is used quickly though and so causes the blood sugar levels to decrease which causes a crash often manifested as lethargy.
- We eat the sugary item which releases opioids. These opioids cause cravings which make it hard to resist the sweet treat in front of you. This is not unlike addictions to nicotine or drugs.
- Fructose also impedes the appetite centers of the brain meaning you feel hungry more often and full less quickly than you should.
- The bottom line is that sugar causes the brain to malfunction, sending signals to constantly dump hormones into your body creating insatiable cravings for more and more sugar. Simply put: the more you eat sugar you eat, the more sugar you want.
