Woman Holding Chocolate And MilkThe harmful effects of sugar go means beyond empty calories.
Added sugar is thus unhealthy that it's probably the only worst ingredient in the fashionable diet.
Here are the high 9 reasons to avoid sugar as if your life trusted it (it does).
1. Added Sugar Supplies a Giant Amount of Fructose
The rationale added sugar (and its evil twin… High Fructose Corn Syrup) is dangerous for you, is that it provides a terribly massive amount of fructose.
Sugar (and HFCS) are half glucose, [*fr1] fructose. Glucose is important and will be metabolized by just about each cell in the body. If we have a tendency to don’t get it from the diet, our bodies create it from proteins and fat.
Fructose, but, isn't essential to our functioning in any means.
The only organ that may metabolize fructose is the liver, because only the liver contains a transporter for it (1).
When giant amounts of fructose enter the liver and it's already full of glycogen, most of the fructose gets was fat (a pair of).
This process is most likely one amongst the leading causes of the epidemics of many chronic, Western diseases.
I’d like to point out that this does NOT apply to fruit, that are a true food with vitamins, minerals, fiber, heaps of water and are terribly difficult to overeat on.
Bottom Line: The only organ which will metabolize fructose is that the liver. After we eat a lot of fructose, many things in the body start to travel wrong.
a pair of. Sugar Doesn’t Contain Any Vitamins or Minerals (Empty Calories)
Junk Food
Sugar IS empty calories. No doubt about that.
Most high-sugar foods like pastries, sodas and candy bars contain very little essential nutrients.
Folks who eat them rather than alternative additional nutritious foods can in all probability become deficient in many necessary nutrients.
Bottom Line: Most product with added sugars in them contain very very little nutrients and will so be classified as “empty” calories.
three. Sugar Causes Deposition of Fat within the Liver

After we eat fructose, it goes to the liver.
If liver glycogen is low, such as after a run, the fructose can be used to replenish it (three).
But, most folks aren’t consuming fructose when a protracted workout and their livers are already filled with glycogen.
When this happens, the liver turns the fructose into fat (a pair of).
Some of the fat gets shipped out, however half of it remains within the liver. The fat will build up over time and ultimately cause Non-Alcoholic Fatty Liver Disease (four, 5, half dozen).
Bottom Line: Eating a heap of added sugar (fructose) will cause deposition of fat within the liver and lead to Non-Alcoholic Fatty Liver Disease.
4. Sugar Harms Your Cholesterol and Triglycerides
Recent Man Taking Pills
Most of the fat generated within the liver gets shipped out as Terribly Low Density Lipoprotein (VLDL) particles.
These particles are made in triglycerides and cholesterol.
In an exceedingly controlled study, folks were assigned to drink twenty fivepercent of calories as either a glucose-sweetened drink or a fructose-sweetened drink for 10 weeks (7).
The fructose group had:
Increases in blood triglycerides.
Increases in small, dense LDL and oxidized LDL (very, very bad).
Higher fasting glucose and insulin.
Decreased insulin sensitivity.
Increased fat in the abdominal cavity (visceral fat).
Basically, 25% of calories as fructose significantly harmed blood lipids and caused features characteristic of the metabolic syndrome, which is a stepping stone towards obesity, heart disease, diabetes and a (short) lifetime of poor health.
Bottom Line: Consuming a large part of calories as fructose can cause serious adverse effects on blood markers in as very little as ten weeks.
five. Sugar Causes Insulin Resistance
Measure Blood Sugar
The main operate of insulin is to drive glucose from the bloodstream into cells.
However once we eat a Western diet, the cells tend to become immune to the consequences of insulin.
When this happens, the pancreas begin secreting even a lot of insulin to get rid of the glucose from the bloodstream, as a result of elevated blood glucose is toxic.
This is how insulin resistance ends up in elevated insulin levels in the blood.
But insulin additionally has another necessary perform… it tells the fat cells to choose up fat from the bloodstream and to carry on to the fat that they already carry.
This is how insulin causes obesity.
When the body becomes even a lot of resistant to insulin, the beta cells in the pancreas eventually become damaged and lose the power to supply sufficient insulin. This is how you get sort II diabetes, that currently afflicts regarding three hundred million folks worldwide.
Excess fructose could be a known cause of insulin resistance and elevated insulin in the blood (eight, nine, ten).
Bottom Line: Excess fructose consumption will result in insulin resistance, a stepping stone towards obesity and diabetes.
half dozen. Sugar Raises Your Risk of Western Diseases
Doctor Thumbs Down
Excess sugar consumption has been related to several Western diseases.
If something, sugar is the only largest contributing issue to the poor health of affluent nations.
Each time sugar (and refined flour and vegetable oils) enter a population’s diet, these people become sick.
Sugar has been related to:
Obesity. Sugar causes weight gain via varied mechanisms, as well as elevated insulin and leptin resistance (eleven, twelve).
Diabetes. Sugar is most likely a leading cause of diabetes (13, fourteen, fifteen).
Heart disease. Sugar raises the unhealthy cholesterol, triglycerides and causes varied other issues that may ultimately result in heart disease (sixteen, 17).
Bottom Line: Excess sugar consumption has been associated with several serious diseases, as well as obesity, sort II diabetes and cardiovascular disease.
seven. Sugar Doesn’t Cause Proper Satiety

An area in the brain called the Hypothalamus is meant to manage our food intake.
During a study revealed in 2013, two groups drank either a glucose-sweetened drink or a fructose-sweetened drink (18).
The glucose drinkers had decreased blood flow in the hypothalamus and felt satiated, while the fructose drinkers had increased blood flow in this area of the brain.
The fructose drinkers felt less satisfied and were still hungry.
Another study revealed that fructose didn’t reduce levels of the hunger hormone ghrelin like glucose. The more ghrelin, the hungrier you're (nineteen).
Bottom Line: Studies comparing fructose and glucose show that fructose will not induce satiety like glucose, that can contribute to the next calorie intake.
eight. Sugar is Addictive

After we eat sugar, dopamine is released in the brain, giving us a feeling of delight.
This is really how medicine of abuse like cocaine perform (twenty).
Our brain is hardwired to seek out activities that release dopamine. Activities that unharness an huge quantity of it are especially desirable.
In sure individuals with a sure predisposition to addiction, this causes reward-seeking behavior typical of addiction to abusive medicine.
Studies in rats demonstrate that they'll of course become physically addicted to sugar (twenty one).
This is tougher to prove in humans, however many individuals consume sugar and different junk foods in an exceedingly pattern that's typical for addictive, abusive compounds.
Bottom Line: Sugar, due to its powerful effects on the reward system in the brain, will cause classic signs of addiction.
9. Sugar Causes Resistance to a Hormone Called Leptin

Leptin may be a hormone that is secreted by our fat cells. The a lot of fat we tend to have, the more leptin is secreted.
This is supposed to perform as a signal to inform the brain that we tend to’re full and want to stop eating. It's conjointly supposed to lift our energy expenditure.
Obese people really have high levels of leptin, however the problem is that the leptin isn’t operating.
This is named leptin resistance and may be a major reason why folks eat more calories than they burn and become obese.
Fructose is a known reason for leptin resistance, each as a result of insulin blocks leptin signalling in the brain and as a result of fructose raises blood triglycerides which conjointly blocks the effects of leptin (22, 23, twenty four).
This makes our brain think that the fat cells are empty which it desires to stay eating.
Willpower is terribly weak compared to the leptin-driven starvation signal.
This is the rationale people can’t just “eat less, move additional” and live happily ever once.
To reverse leptin resistance and create the brain WANT to eat less, sugar has to go.
