In the United States, the typical adult consumes an estimated 17 teaspoons of added sugar every day (1Trusted Source). That accounts for 14% of whole calorie intake in adults following a 2,000-calorie diet.

Experts imagine that sugar consumption is a serious cause of obesity and many chronic diseases, such as type 2 diabetes (2Trusted Source).

That’s why dietary tips counsel limiting calories from added sugar to less than 10% per day (3Trusted Source).

Here are 11 explanation why eating too much sugar is dangerous for your health.

1. It Can Cause Weight Gain

Obesity charges are rising worldwide, and proof means that added sugar — usually from sugar-sweetened beverages — is a serious contributor to weight problems (4Trusted Source).

Sugar-sweetened drinks like sodasjuices, and sweet teas are loaded with fructose, a sort of simple sugar.

Consuming fructose will increase your hunger and need for food more than glucose, the principle sort of sugar found in starchy foods (5Trusted Source).

Additionally, consuming too much sugar, especially from sugar-sweetened drinks, has been linked to atherosclerosis, a disease characterised by fatty, artery-clogging deposits (13).

A examine in over 25,877 adults found that individuals who consumed extra added sugar had a higher risk of developing heart disease and coronary issues compared to individuals who consumed much less added sugar (10).

Not only does increased sugar intake increase cardiovascular risk, but it could also increase risk of stroke (10).

In the same examine, more than eight servings per week of sugar-sweetened beverages have been related to increased stroke risk (10).

Just one 12-ounce (473-ml) can of soda contains 39 grams of sugar, which equates to eight% of your every day calorie consumption, based mostly on a 2,000-calorie diet (14).

This signifies that one sugary drink a day can carry you near the recommended daily limit for added sugar.

Evidence has proven that low-glycemic diets are related to a reduced zits risk, while high-glycemic diets are linked to a better zits risk (17Trusted Source).

For instance, a examine of 24,452 participants found that the consumption of fatty and sugary products, sugary beverages, and milk was related to present zits in adults (18Trusted Source).

Additionally, many population studies have proven that rural communities that consume traditional, non-processed foods have much lower charges of zits compared to extra city, high-income areas the place processed food is part of a regular diet (19Trusted Source).

These findings coincide with the idea that diets high in processed, sugar-laden foods contribute to the event of zits.

While no examine has confirmed that sugar consumption causes diabetes, there are strong connections.

Eating large amounts of sugar can not directly elevate diabetes risk by contributing to weight gain and increased body fat — each of that are dangers for developing diabetes (22Trusted Source).

Obesity, which is commonly attributable to extreme sugar consumption, is taken into account the strongest risk issue for diabetes (23Trusted Source).

Other studies have found sugar intake to be linked to particular types of most cancers.

A examine in over 22,720 males spanning over 9 years found that increased sugar consumption from sugar-sweetened beverages was related to a higher risk of prostate most cancers (30Trusted Source).

In the liver, fructose is transformed into energy or saved as glycogen.

However, the liver can only retailer so much glycogen before extra amounts are became fat.

Large amounts of added sugar in the shape of fructose overload your liver, resulting in nonalcoholic fatty liver disease (NAFLD), a condition characterised by extreme fat buildup in the liver (45Trusted Source).

An animal examine found that feeding mice a high-fructose diet for long periods of time led to the deterioration of their intestinal barrier, liver inflammation, liver tumors, and signs of fatty livers compared to a control group (46Trusted Source).

The same examine found that the same amount of fructose is extra prone to result in developing a fatty liver when consumed through beverages fairly than food, and when consumed in a single setting compared to a number of doses spread over an extended amount of time (46Trusted Source).

A examine in over 5,900 adults confirmed that people who drank sugar-sweetened beverages every day had a 56% increased risk of developing NAFLD, compared to people who didn’t (47Trusted Source).


Eating too much sugar could result in NAFLD, a condition in which extreme fat builds up in the liver.
