why is sugar bad for you?

Sadly, most people today rely on processed foods. These processed foods contain added sugar, and when people consume them daily, they increase their chances of developing conditions associated with excessive sugar consumption. Sugar consumption is one of the major factors that cause obesity, cardiovascular diseases, and diabetes.

As such, you need to consider cutting down on sugar if you want to have a healthy lifestyle and mitigate the risks of developing conditions caused by sugar consumption.

A healthy way of cutting down on sugar or foods that contain added sugar is by consuming a ketogenic diet.

A ketogenic diet helps you reduce weight because it helps in reducing your appetite, which means that you will eat less and not gain weight.

Also, eating a ketogenic diet reduces the amount of blood sugar, which is an excellent way of reducing the chances of developing conditions such as diabetes, for instance.

Furthermore, a ketogenic diet helps lower blood pressure, which helps reduce the risks of hypertension and other cardiovascular diseases. Indeed, it may not be easy for you to cut down on sugar consumption.

It will be best for you to start slowly, and you will eventually get rid of the excessive sugar in your diet.

In this piece, we have outlined some of the reasons why sugar is dangerous to your health and how you can reduce your sugar intake. It is important since it improves your health and quality of life, which will help you to live longer.

How is Sugar Digested?

When you eat starch that contains sugar, its digestion starts in the mouth. The starch is acted upon by the salivary amylase to ensure that it is hydrolyzed for easier digestion in the stomach.

When the starch reaches the stomach, the salivary amylase becomes deactivated, meaning it is not effective anymore.

Another enzyme in the small intestine called the pancreatic amylase takes over the digestion process. It breaks down the starch into other smaller molecules called maltose and dextrin.

Again, there are also other enzymes called glucosidases, which then act on dextrin, breaking it down to simpler molecules of maltose, which are then converted into glucose.

The glucose is absorbed by the small intestine walls, where it enters into the portal vein and is transported to the liver, where it is stored as glycogen.

What Does Sugar Do To Your Body?

Heart Disease

Generally, sugar massively increases your chances of developing a heart condition. When you consume added sugars every day, you increase your chances of developing diabetes, which is a major risk factor that increases your chance of developing fatal heart disease.

Also, when you eat added sugars in your meals every day, you increase your blood sugar and insulin levels, which may make you obese. Ideally, obesity is also another risk factor that increases your likelihood of developing a chronic heart condition.

The excessive sugar in your blood will also inhibit the triglycerides from breaking down.

This will make the triglycerides accumulate in the blood, which causes cardiovascular complications because these triglycerides are excessive fat in the blood that causes heart diseases.

Furthermore, excessive sugar in the blood increases your risk of developing heart disease because they increase low-density lipoprotein cholesterol levels, which is bad cholesterol.

They also reduce the level of high-density lipoprotein, which is good cholesterol. According to experts, people who take excessive sugar are more likely to die of heart disease than people who take sugar in the appropriate quantities.

Overweight and Obesity

In general, sugar contains high levels of empty calories. Ideally, that is why most people who enjoy eating candy and cookies are usually overweight.

You need to realize that the sugar in candy, ice creams, and cookies contains empty calories. If you overindulge in eating these things, you may gain excessive weight, leading to obesity.

When you take in sugary food, you may develop hyperglycemia, which will promote insulin resistance in the body. In a real sense, insulin is produced by the pancreas so that it can help with the regulation of the blood sugar level in the body.

Insulin is also important because it helps store energy in the body by redirecting body cells to store the glycogen and fat from glucose.

This means that when insulin resistance occurs, the cells will not function normally because they will be unresponsive to insulin.

Nevertheless, while the cells are not responsive to insulin, they remain responsive to the other hormones that play a huge role in storing fat. This means that fat storage increases in the body, leading to obesity.

High Blood Pressure

Scientific studies have shown that there is a close correlation between high blood pressure and excessive sugar consumption. For instance, excessive sugar consumption leads to insulin resistance, which directly leads to high blood pressure.

sugar and high blood pressure

Essentially, insulin helps by storing magnesium, which helps blood vessels relax in the body. Insulin resistance means that it will no longer be as effective in the body, which means that the magnesium available will not get stored, as it will be passed out of the body through urine.

This will make the blood vessels constrict and cause the blood pressure to increase.

Besides, excessive sugar consumption also leads to excess uric acid in the body, inhibiting nitric oxide that helps maintain ideal blood pressure.

Ideally, nitric oxide helps in vasodilation, which helps make the blood vessels remain elastic to regulate blood pressure.

In a nutshell, if they are inhibited, the blood pressure level will be high. In order to prevent high blood pressure, it will be best for you to avoid foods that contain added sugars.

Increase Chronic Inflammation

Excessive sugar in the body makes the liver produce fatty acids. When these fatty acids undergo digestion, they result in chronic inflammation in the body.

This means that the more sugar you consume, the higher your chances of developing chronic inflammation in the body. There is research that suggests that different types of sugars cause different levels of inflammation in the body.

According to the research, there are some types of sugar like fructose, for instance, that cause excessive inflammation, and there are those like glucose that cause mild inflammation.

The different types of inflammation vary in symptoms, depending on how severe the inflammation is. We have outlined some of the common symptoms of chronic inflammation below.

-Weight gain

-Body pain



-Anxiety and depression


Type 2 Diabetes

Undoubtedly, excessive sugar in the body is the top cause of type 2 diabetes. When you consume excessive sugar, you are promoting insulin resistance in your body.

Essentially, when insulin resistance occurs, the pancreas tries to overcome it by producing more and more insulin so that it can regulate the level of sugar in the body.

With time, the pancreas becomes overwhelmed, and it is unable to produce more insulin, which makes the blood sugar level to rise, leading to type 2 diabetes. The only way to prevent contracting type 2 diabetes is to avoid eating excessive sugar.

This way, insulin resistance will not occur in your body, guaranteeing that the pancreas will produce sufficient insulin to regulate the blood sugar level normally.

Fatty Liver

Excessive consumption of sugar leads to non-alcoholic fatty liver disease. It occurs when excess fat is deposited in the walls of the liver. This disease progresses slowly, and you may not even notice it until it is too late.

Research shows that non-alcoholic fatty liver disease may go unnoticed for over two decades, and when the symptoms start to show, it may be too late.

When this fat deposit becomes too much on the liver, it may lead to liver cirrhosis or, sometimes, if it is too advanced, it may lead to liver cancer.

Tooth Decay

Generally, your mouth contains bacteria. Some of these bacteria may have essential functions in your mouth, while some may not be so good, hence, harmful.

sugar and tooth decay

When you eat sugary foods, the harmful bacteria in your mouth will act on them and produce harmful acids. These acids destroy the enamel of your teeth, leading to tooth decay and cavities.

When they go too deep inside the tooth, they create small holes, which are very painful. In the long run, you may end up losing your teeth since it is the ultimate treatment for tooth decay.

Be sure to avoid sugary food if you want to avoid losing your tooth due to tooth decay.


Dermatologists suggest that there is a close correlation between excessive sugar consumption and recurring acne. Ideally, eating excessive sugar leads to the accumulation of fat and dead skin, leading to acne.

Cutting down on excessive sugar consumption will be a great way of mitigating the risks of acne occurring.

Depression and Drained Energy

Eating sugary foods is also a risk factor for depression. When you eat foods containing a lot of sugar, your body will use a lot of energy to digest them, which leaves you tired, leading to drained energy.

Also, whenever you eat sugary foods, it leads to an imbalance of the blood sugar level, which greatly brings down your energy levels, and it affects your mood, leading to depression.

Indeed, eating sugary food has many adverse effects on your health. Be sure to cut down on the sugar you eat every day to ensure that you will lead a healthy lifestyle. An excellent way of doing this will be eating a ketogenic diet.
