How Does Sugar Affect Your Body?

Small amounts of sugar are good for you, but too much can increase your risk of weight gain, acne, type 2 diabetes, and other major medical disorders.You can find added sugar in even the most unlikely goods, such peanut butter and marinara sauce.

A lot of people only eat fast, processed food for lunch and snacking. Because these goods frequently include added sugar, a significant amount of their daily calorie intake comes from them.

The average adult in the US is thought to ingest 17 teaspoons of added sugar daily. That makes up 14% of the total calories consumed by adults on a 2,000 calorie diet.Experts contend that consuming sugar plays a significant role in the development of many chronic illnesses, including type 2 diabetes and obesity.

For this reason, dietary standards recommend consuming no more than 10% of daily calories from added sugar.

These are ten reasons that eating too much sugar is unhealthy.

1. It Could Lead To Gaining Weight

Gaining Weight

Global obesity rates are on the rise, and research indicates that added sugar, frequently from beverages sweetened with sugar, has a significant role in obesity.

Drinks containing added sugar, such as juices, sodas, and sweet teas, are high in fructose, a form of simple sugar.

Compared to glucose, the primary sugar present in starchy foods, fructose stimulates appetite and cravings for eating.

Furthermore, research on animals suggests that consuming too much fructose may lead to resistance to leptin, a crucial hormone that controls hunger and signals the body to stop eating.

Put differently, sugar-filled drinks don’t satisfy your appetite, which makes it simple to ingest a large amount of liquid calories rapidly. Gaining weight could result from this.

Sugar-filled beverages have been linked to weight gain and a higher risk of type 2 diabetes, according to research.

Moreover, consuming a lot of sugar-sweetened beverages has been connected to a rise in visceral fat, or deep abdominal fat linked to diseases including diabetes and heart disease.


Excessive consumption of added sugar, particularly from sugar-filled drinks, raises the risk of weight gain and can cause the buildup of visceral fat.

2. Might Raise Your Heart Disease Risk

Heart Risk

Diets high in sugar have been linked to a higher risk of heart disease, the leading cause of mortality worldwide, among other illnesses.

Research indicates that eating a diet heavy in sugar might increase blood pressure, lipids, blood sugar, and obesity, all of which are risk factors for heart disease.

Furthermore, excessive sugar consumption—especially from drinks with added sugar—has been connected to atherosclerosis, a condition marked by deposits of fat that clog arteries.

More added sugar consumption was linked to an increased risk of heart disease and coronary problems compared to lower added sugar consumption, according to a study involving approximately 25,877 persons.

Consuming more sugar not only raises the risk of cardiovascular disease but also increases the risk of stroke.

In the same study, consuming more than eight servings of sugar-sweetened beverages per week was linked to a higher risk of stroke.

39 grams of sugar, or 8% of your daily caloric intake based on a 2,000-calorie diet, are found in just one 12-ounce (473-ml) can of soda.

In other words, you can almost reach the daily recommended limit for added sugar with just one sugary drink per day.


Consuming added sugar raises blood pressure, inflammation, and obesity—three risk factors for heart disease. Increased risk of heart disease has been associated with high-sugar diets.

3. Connection to Acne


A diet high in refined carbs, including sticky foods and drinks, has been associated with a advanced threat of developing acne. Foods with a advanced glycemic indicator, similar as reused sweets, raise your blood sugar more fleetly than foods with a lower glycemic indicator.

Consuming sticky foods can beget a shaft in blood sugar and insulin situations, leading to increased androgen stashing, oil painting product, and inflammation — all of which play a part in acne development.

substantiation has shown that low- glycemic diets are associated with a reduced acne threat, while high- glycemic diets are linked to a advanced acne threat. For illustration, a study of 24,452 actors set up that the consumption of adipose and sticky products, sticky potables, and milk was associated with current acne in grown-ups. also, numerous population studies have shown that pastoral communities that consume traditional,non-processed foods have much lower rates of acne compared to further civic, high- income areas where reused food is part of a standard diet.

These findings coincide with the proposition that diets high in reused, sugar- laden foods contribute to the development of acne.

For instance, consumption of milk, sugary drinks, and fatty and sugary items was linked to adult acne, according to a study involving 24,452 participants.

Furthermore, compared to more urban, affluent places where processed food is a staple of the diet, acne rates are significantly lower in rural groups that eat traditional, non-processed cuisine.

These results are consistent with the hypothesis that diets heavy in processed, sugar-filled foods cause acne.

Diets high in sugar can increase the creation of oil, inflammation, and testosterone secretion, all of which can increase the risk of acne.

4. Raises Your Chances of Diabetes Type 2

Diabetes is a major factor in mortality and shortened life spans. The past 30 years have seen a more than double increase in its prevalence, and future estimates indicate that its burden will only increase.

A higher risk of diabetes has long been linked to excessive sugar consumption.

There is a substantial correlation between sugar consumption and diabetes, even though no study has found a direct relationship.

A high sugar diet can indirectly increase the risk of getting diabetes by causing weight gain and an increase in body fat, both of which are risk factors for the disease.

The biggest risk factor for diabetes is obesity, which is frequently brought on by consuming too much sugar.

Moreover, a prolonged high-sugar diet causes resistance to insulin, a pancreatic hormone that controls blood sugar levels.

Insulin resistance raises blood sugar levels and significantly raises the chance of developing diabetes.

Furthermore, studies have shown a higher risk of diabetes development in those who consume beverages sweetened with sugar.

Increased intake of sugary beverages, such as soft drinks and 100% fruit juice, has been linked to a higher risk of type 2 diabetes, according to a study that included participants who drank sugary beverages for more than four years.

One of the risk factors for type 2 diabetes is obesity, and a high-sugar diet can contribute to insulin resistance.

5. Could Raise Your Chances of Depression


A diet rich in processed foods and added sugars can lead to mood swings, even though a balanced diet can assist elevate your emotional state.

It might even make you more susceptible to depression.

Increased sugar intake has been connected to emotional illnesses like anxiety and sadness, memory issues, and cognitive deficits.

Sugar’s adverse effects on mental health may be attributed to a number of factors, including chronic systemic inflammation, insulin resistance, and a disturbed dopaminergic reward signaling system, all of which can be brought on by consuming more sugar.

those who consumed 67 grams or more of sugar per day had a 23% higher risk of developing depression than those who consumed less than 40 grams, according to a study including 8,000 participants.

Another study including more than 69,000 women showed that the greatest intakeers of added sugars were notably more likely to experience depression than the lowest intakeers.


Eating a diet high in processed foods and added sugar may put men and women at risk for depression.

6. Might Raise Your Cancer Risk

Consuming too Important sugar can raise your chance of getting some types of cancer.

First out, eating a lot of sugar- filled refections and drinks can beget rotundity, which dramatically increases your chance of developing cancer.

Also, a diet heavy in sugar raises your body’s seditious response and may lead to insulin resistance, all of which raise your threat of developing cancer.

A 60 – 95 increased cancer threat was noted with advanced sugar consumption in two of the five studies on added sugar, according to a methodical analysis assessing 37 prospective cohort studies.

According to the same review, consuming more sugary beverages was linked to a 23%–200% higher risk of cancer in 8 out of 15 research on sugary foods and beverages.

Consumption of sugar has been connected in other research to particular forms of cancer.

An increased risk of prostate cancer was linked to increasing sugar consumption from beverages sweetened with sugar, according to a study conducted over a period of nine years on 22,720 males.

According to a different study, consuming more sucrose, or table sugar, and sweetened drinks and desserts, was linked to an increased risk of esophageal cancer.

Further research is required to completely comprehend this intricate relationship between added sugar consumption and cancer, and research on this topic is still underway.


An excessive amount of sugar raises the risk of obesity, insulin resistance, and inflammation, all of which are linked to cancer.

7.Could Quicken the Process of Skin Aging

Skin aging

Ageing skin naturally develops wrinkles. No matter how well you’re doing, they will eventually surface.

Poor dietary choices, however, can hasten the aging process of the skin and exacerbate wrinkles.

The molecules known as advanced glycation end products (AGEs) are created when sugar and protein interact within your body. They are thought to be crucial in the aging of the skin.

Eating a lot of sugar and refined carbohydrates causes the body to produce AGEs, which can prematurely age your skin.

The proteins collagen and elastin, which aid in the skin’s ability to stretch and maintain its youthful appearance, are harmed by AGEs.

The skin becomes less firm and starts to droop when collagen and elastin are destroyed.

To completely comprehend how sugar affects changes in human skin, more research is required.


Consuming sugary foods might raise the amount of AGEs produced, hastening the aging process and the development of wrinkles on the skin.

8. Empties Your Energy

Foods with a lot of added sugar cause blood sugar and insulin levels to rise quickly, which increases energy.

This increase in energy is momentary, though.

Products high in sugar but low in fat, protein, or fiber provide a short-lived energy spike that is rapidly followed by a precipitous drop in blood sugar, sometimes known as a “crash.”

Abnormal blood sugar levels can cause significant variations in one’s energy levels.

Consuming carbohydrates, particularly sugar, reduces alertness within 60 minutes of consumption and increases fatigue within 30 minutes of consumption, according to a meta-analysis looking at the impact of sugar on mood.

To avoid this energy-draining cycle, choose carb sources that are low in added sugar and rich in fiber.

Pairing carbs with protein or fat is another great way to keep your blood sugar and energy levels stable.

For example, eating an apple along with a small handful of almonds is an excellent snack for prolonged, consistent energy levels.


High-sugar foods can negatively impact your energy levels by causing a spike in blood sugar followed by a crash.

9.May Accelerate Cellular Aging

Telomeres are structures found at the end of chromosomes, which are molecules that hold part or all of your genetic information.

Telomeres act as protective caps, preventing chromosomes from deteriorating or fusing together.

As you grow older, telomeres naturally shorten, which causes cells to age and malfunction (39Trusted Source).

Although the shortening of telomeres is a natural part of aging, certain lifestyle choices can speed up the process.

Consuming high amounts of sugar has been shown to accelerate telomere shortening, which increases cellular aging .

A pilot study on 61 preschool-aged children found that increased consumption of sugar-sweetened beverages was associated with decreased telomere length, signifying cellular aging


Consuming high amounts of sugar has been shown to accelerate telomere shortening, which increases cellular aging 

10. Can Cause Liver Fat

A high fructose diet has been repeatedly associated with a higher incidence of fatty liver.

HFCS, or high fructose corn syrup, is a primary source of fructose, which is commonly used to sweeten soda, candies, baked goods, cereals, and other foods.

Fructose is nearly entirely broken down by the liver, in contrast to glucose and other sugars that are absorbed by numerous cells throughout the body.

Fructose is either stored as glycogen or transformed into energy in the liver.

But the quantity of glycogen the liver can store before it is converted to fat is limited.

Large doses of fructose, an added sugar, overload your liver and cause nonalcoholic fatty liver disease (NAFLD), a disorder marked by an abnormal accumulation of fat in the liver.

According to an animal study, mice fed a high-fructose diet over extended periods of time had liver tumors, fatty liver symptoms, and deteriorated intestinal barriers as compared to a control group.

The same study discovered that consuming the same quantity of fructose in a single setting as opposed to multiple doses spaced out over a longer period of time increases the risk of developing a fatty liver.

A study including more than 5,900 participants revealed that daily use of sugar-sweetened beverages was associated with a 56% increased risk of non-alcoholic fatty liver disease (NAFLD) development.


Nationally acquired fatty liver disease (NAFLD) is a disorder that can result from consuming an excessive amount of sugar.

11.Other Health Risks

In addition to the dangers mentioned above, sugar has a host of other negative effects on your health.

Studies reveal that an excess of added sugar may:

Raise risk of renal disease : Fructose can raise urate levels in the blood, which can result in kidney disease. The fragile blood veins in your kidneys can be harmed by persistently high blood sugar, which raises your chance of developing kidney disease.
Detrimental effect on dental health : Too much sugar consumption might lead to cavities. Teeth demineralization is a result of acid byproducts released by oral bacteria that consume sugar.

Accelerate cognitive decline: Diets high in sugar have been connected to a higher risk of dementia, Alzheimer’s disease, and stroke in addition to impairing memory.
New findings about the effects of added sugar on health are always being investigated.


Too much sugar intake can damage your kidneys, raise your risk of developing gout, exacerbate cognitive decline, and result in cavities.

How to Consume Less Sugar

Too much added sugar has a number of detrimental impacts on health.

While occasional tiny quantities are totally OK, you should always aim to reduce your intake of sugar.

Fortunately, cutting back on sugar in your diet is as simple as emphasizing complete, unadulterated foods.

Here are some pointers for cutting back on added sugar consumption:

  • Water or unsweetened seltzer should be substituted for sodas, energy drinks, juices, and sweetened teas.
  • For a healthy option, try a natural alternative or drink your coffee black.
  • Instead of purchasing flavored, sugar-laden yogurt, add some sweetness to plain yogurt by adding fresh or frozen berries.
  • Eat the fruits whole rather than in fruit smoothies that have added sugar.
  • Make your own trail mix with nuts, fruit, and a few dark chocolate chips instead of candies.
  • Swap out sugary salad dressings like honey mustard for olive oil and vinegar.
  • Select ketchup, marinara sauce, nut butters, and marinades that have no added sugar.
  • Look for cereals that have less than 4 grams of sugar per serving, as well as granola and granola bars.
  • Instead of cereal in the morning, try an omelet with fresh greens or a bowl of rolled oats topped with nut butter and fresh berries.
  • Scoop some fresh bananas onto your peanut butter sandwich in place of the jelly.
  • Instead of using sugary spreads like Nutella, try natural nut butter.
  • Steer clear of alcoholic drinks that have been sweetened with agave, soda, juice, honey, or sugar.
  • When you shop around the grocery store, pay attention to the fresh, entire ingredients.

Furthermore, maintaining a food journal is a great method to identify the primary sources of sugar in your diet.

Make your own nutritious meals at home and stay away from purchasing foods and beverages that are rich in added sugar as the best ways to reduce your intake of added sugar.

Reducing your intake of items with added sweeteners and concentrating on cooking healthful meals are two ways to reduce the amount of sugar in your diet.
