Sugar is bad for you a) because it has calories, and b) because if you have diabetes or a diabetes-related condition — lets say high blood fat levels — then having sugar will increase your blood sugar and your triglycerides, which is a risk factor for heart disease. (Triglycerides are a type of fat in the blood)
Here are 10 disturbing reasons why you should cut back on Eating Sweets & Candy.
Added Sugar Contains No Essential Nutrients and is Bad For Your Teeth - You’ve probably heard this a million times before… but it’s worth repeating.Added sugars (like sucrose and high fructose corn syrup) contain a whole bunch of calories with NO essential nutrients.For this reason, they are called “empty” calories.There are no proteins, essential fats, vitamins or minerals in sugar… just pure energy.When people eat up to 10-20% of calories as sugar (or more), this can become a major problem and contribute to nutrient deficiencies.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 - In order 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.Glucose is found in every living cell on the planet. If we don’t get it from the diet, our bodies produce it.Fructose is different. Our bodies do not produce it in any significant amount and there is no physiological need for it.The thing with fructose 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.Keep in mind that all of this does NOT apply to fruit. It is almost impossible to overeat fructose by eating fruit.There is also massive individual variability here. People who are healthy and active can tolerate more sugar than people who are inactive and eat a Western, high-carb, high-calorie diet.
Sugar Can Cause Insulin Resistance, a Stepping Stone Towards Metabolic Syndrome and Diabetes - Insulin is a very important hormone in the body.It allows glucose (blood sugar) to enter cells from the bloodstream and tells the cells to start burning glucose instead of fat.Having too much glucose in the blood is highly toxic and one of the reasons for complications of diabetes, like blindness.One feature of the metabolic dysfunction that is caused by the Western diet, is that insulin stops working as it should. The cells become “resistant” to it.This is also known as insulin resistance, which is believed to be a leading driver of many diseases… including metabolic syndrome, obesity, cardiovascular disease and especially type II diabetes.Many studies show that sugar consumption is associated with insulin resistance, especially when it is consumed in large amounts.
The Insulin Resistance Can Progress to Type II Diabetes - When our cells become resistant to the effects of insulin, the beta cells in our pancreas make more of it.This is crucial, because chronically elevated blood sugars can cause severe harm.Eventually, as insulin resistance becomes progressively worse, the pancreas can’t keep up with the demand of producing enough insulin to keep blood sugar levels down.At this point, blood sugar levels skyrocket and a diagnosis of type II diabetes is made.Given that sugar can cause insulin resistance, it is not surprising to see that people who drink sugar-sweetened beverages have up to an 83% higher risk of Type II diabetes.
Due to its Effects on Hormones and the Brain, Sugar has Unique Fat-Promoting Effects - Not all calories are created equal.Different foods can have different effects on our brains and the hormones that control food intake.Studies show that fructose doesn’t have the same kind of effect on satiety as glucose.In one study, people drank either a fructose-sweetened drink or a glucose-sweetened drink.Afterwards, the fructose drinkers had much less activity in the satiety centers of the brain and felt hungrier .There is also a study where fructose didn’t lower the hunger hormone ghrelin nearly as much as glucose did.Over time, because the calories from sugar aren’t as fulfilling, this can translate into an increased calorie intake.
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.Woman Snorting DoughnutsThe problem with sugar and many junk foods is that they can cause massive dopamine release… much more than we were ever exposed to from foods found in nature.For this reason, people who have a susceptibility to addiction can become strongly addicted to sugar and other junk foods.The “everything in moderation” message may be a bad idea for people who are addicted to junk food… because the only thing that works for true addiction is abstinence.
