- You might as well drink! It’s all the same to your organs
- The new drug of choice
- One sugar to ruin them all.
Dear Reader,
Recently, Living Well Daily has received some reader mail regarding the dangers of sugar and a few requests to break this down a bit further.
So that’s just what we are doing today.
And it only seems fitting as I am reporting to you from West Virginia — the nation’s leader in Type 2 diabetes — but we will dig into that and how some passionate local groups (including the National Park Service) are trying to change the health of West Virginians in a later episode.1
For now, we will explain three ways sugar is ruining your health and likely sending you to an early grave.
I want to be clear: These aren’t the only dangers associated with sugar. But rather three significant ones that make more sense when thoroughly explained.
Let’s get started!
Fatty Liver Disease
Fructose, the sugar found in fruit, was once a very minuscule part of the American diet. In fact, the daily average intake amount was around a half an ounce in the early 20th century. Unfortunately, we consume four–five times that amount in current times due to the introduction of processed foods.
What makes fructose so dangerous for the liver? Unlike glucose, the other main type of sugar in our diet, fructose can only be broken down by liver cells.
When you eat fructose, it begins a series of chemical reactions in the liver. These reactions happen because your liver is turning fructose into fat. If the liver becomes overloaded with fructose, small fat deposits start to collect in liver cells.

This fatty buildup can also be caused by alcohol abuse, so this specific type is referred to as nonalcoholic fatty liver disease. The condition, which may lead to cirrhosis, was pretty much unknown before 1980 but now affects about 30% of adults in developed countries. If caught early enough, nonalcoholic fatty liver disease is reversible.2
High fructose corn syrup is about 60 percent fructose. Fatty liver disease is yet another reason to avoid it.
Sugar Gives You Heart Disease
Though I have touched on this in a previous article, I will explain it in greater detail today.
Heart disease is the leading killer of adults in the world. For many decades, saturated fats have taken the blame for this deadly disease. But as it turns out, studies have proven it just isn’t true.3
However, in recent years, it’s come to light that sugar — and, once again, specifically fructose — causes heart disease.
As I mentioned in the previous section, fructose is only processed by the liver. This processing causes elevated triglycerides in the bloodstream and can lead to an increase in LDL cholesterol levels as well.
Even more frightening, fructose promotes the fat accumulation around organs and raises blood pressure, and it can lead to other negative heart changes like hardening of the arteries. 4
In addition, the link between heart disease and sugar has been backed by many studies.
Sugar Is Addictive
Just like many drugs, sugar has highly addictive properties.
And while you may not see a lot of folks walking around mainlining Twinkies, you probably have seen people jonesing for a soda or a sticky bun in the morning.
Is sugar the new cocaine?

Here’s why…
When sugar enters the bloodstream, it releases dopamine, a chemical that helps control the pleasure and reward center of the brain. Processed foods have much higher levels of sugar (mostly fructose) than is found in natural foods. This massive sugar influx can cause a tidal wave of dopamine to release in your brain — similar to snorting a line of cocaine.
In fact, one study found that rats would actually choose sugar over cocaine, even after being addicted to cocaine.5,6
Sugar is one hell of a drug.
Due to these huge amounts of sugar, it’s suspected that people with a predisposition to addiction can also become addicted to sugary junk foods. For this reason, it’s likely that total abstinence is the best choice when it comes to high-sugar foods.
Seize the Sugar
As it seems, sugar can cause major damage to your vital organs and even cause you to crave it like a drug.
Since most research is based on fructose, it seems logical to steer clear of all fruit sugars. However, this isn’t necessarily true.
Natural sources of fructose, like raw fruits and veggies, add very small amounts of fructose to your daily diet. It’s the processed forms, like high fructose corn syrup and even some juices that add addictive and dangerous amounts.
And since it’s almost farmer’s market season, it’s the perfect time to trade in those cookies for carrots.
Live well,
