As per dietary guidelines, calories from added sugar should be limited to less than 10% per day. Still, in the US, adults on average take added sugars of 17% of the total calorie whereas in children, it accounts for up to 14%.

A person eating more added sugars may fall into the habit of taking less of healthy foods and as a result, may feel deficient in the nutrition, which may result in serious health issues.

2. Increases Risk of Type 2 Diabetes

Diabetes is one of the leading health issues presently. While there are various reasons accountable for the same, increased sugar intake is one of the reasons.

Because high in sugary foods are usually high in calories, it increases the risk of Type 2 Diabetes.

The diet which is high in sugar and carbs leads to a constant release of insulin. This can further lead to insulin resistance which often is the cause of pre-diabetes and Type 2 diabetes.

As suggested by the American Diabetes Association, sugary drinks are specifically the problem behind this, and one should avoid sugary drinks to prevent Type 2 diabetes.

3. May Lead to Weight Gain

Obesity is also one of the major health issues the world is facing, and no doubt added sugars are one of the main reasons.

Once again, it is the sugar-loaded beverages like sodas, juices, etc. That is rich in fructose that is responsible for most of the cases of obesity.

Compared to glucose, the main type of sugar found in starchy foods, fructose increases your appetite, making you eat more. It also results in the resistance of leptin, a hunger controlling hormone that tells your body not to eat anymore.

As a result, you end up drinking or eating more which becomes the reason for the increase in weight.

It is important to understand that sugar in itself does not cause weight gain and obesity. It is rather one of several causes. Being overweight or obese is the result of interaction between multiple factors like diet, physical activity, and genetics, social and environmental factors.

Nevertheless, restricting the amount of sugar in a diet is one of the simplest ways to prevent weight gain.

4. Increased Risk of Heart Disease

Heart disease is the number one reason for deaths worldwide, and it is not surprising to know that diets are one of the major reasons for the same.

As supported by studies, high-sugar diets can result in obesity, inflammation and high triglyceride, blood sugar, and blood pressure levels, all of which are the leading risk factors for heart disease.

Also, consumption of too much sugar from sugar-sweetened drinks have shown to have a clear relation with increased chances of atherosclerosis, a disease characterized by fatty, artery-clogging deposits.

5. Cavities

This does not need much explanation for sure. Since childhood, we are told not to eat too many candies since it may cause a cavity in our teeth which is correct. Increased sugar consumption can cause tooth decay, which may lead to the development of cavities.

When you eat sugar in some form, bacteria present in your mouth form a thin layer of plaque over your teeth. These bacteria then react with the sugars present in foods and drinks. As a result of this reaction, an acid release that leads to damage to the teeth.

More studies are awaited to understand the complex relationship between sugar and cancer.

7. Fatty Liver Disease

One of the reasons for fatty liver is over the storage of glycogen. Fructose funds in the foods are metabolized in the liver, where it is turned into fat and stored as glycogen. But when this glycogen level has been already full (due to high carb diets), it results in fatty liver.

While you eat the whole fruit (which also has fructose), it will not harm you since it has fiber that fills you and prevents you from overeating. But having fruit juice would not mean the same. Fruit juice has all the fiber removed, and thus you are having a lot of sugar compared to one whole fruit.

According to the American Journal of Clinical Nutrition, “There is no biological need for fructose”.

So take less of sugars and save your liver.
