Consuming too much sugar, however, raises the risk of several dangerous health problems, including obesity, type 2 diabetes, increased pressure on the heart and blood vessels, and dental decay.
It is estimated that the average person in the United States consumes around 19.5 teaspoons, or 82 grams (g) of sugar, per day. That is over double the amount recommended by the American Heart Association (AHA), which is 9 teaspoons per day for men and 6 teaspoons for women.
Fast Facts on Sugar Content
Men should eat no more than 9 teaspoons of sugar per day and women no more than 6.
Chocolate bars, sweet cereals, and soda often contain high levels of added sugar.
Fruits contain natural sugars that are less harmful than the sugar found in processed food.
Regularly consuming too much sugar increases the risk of heart disease, diabetes, and obesity.
What is Sugar?

Sugar is a simple carbohydrate that belongs to a class of chemically related sweet-tasting substances. It is available in many different forms.
The three main types of sugar are sucrose, lactose, and fructose.
Even though cells need glucose to survive, consuming too much can cause health problems.
The AHA says that added sugars contribute zero nutrients and are empty calories "that can lead to extra pounds, or even obesity, thereby reducing heart health."
The term "free sugars" refers to any glucose, fructose, and sucrose added to foods and drinks, as well as the sugars that occur naturally in syrups, honey, and fruit juice. The term does not apply to the natural sugars found in fresh fruit, vegetables, or milk because there is no evidence linking these sugars to health problems.
Below are some common everyday foods and drinks, listed with their sugar content.

Risks
The AHA has urged people to cut their intake of added sugar because of evidence that it can lead to the following health conditions:
Obesity: A recent study in QJM found that eating more sugar and consuming artificially sweetened soda is associated with obesity.
Heart disease: Research published in JAMA Internal Medicine investigated sugar intake and deaths related to cardiovascular disease. They concluded that: "Most U.S. adults consume more added sugar than is recommended for a healthy diet. We observed a significant relationship between added sugar consumption and increased risk for cardiovascular disease mortality."
Type 2 diabetes: Although sugar does not directly cause diabetes, individuals who consume more sugar than average are more likely to be overweight, which is a risk factor for type 2 diabetes.
