Have a crazy sweet tooth? Don’t we all. Having some sugar in your diet is fine, and even recommended. In fact, the American Heart Association says men can have a maximum of 150 calories of added sugar per day (which equals out to 37.5 grams or 9 teaspoons) and women should have 100 calories per day (25 grams or 6 teaspoons).

But most of us eat way more than that. The average American consumes 19.5 teaspoons (82 grams) every day, which translates into about 66 pounds of added sugar consumed each year, per person. Holy sugar!

It makes sense, considering how much sugar is added to food these days. Take the obvious sugary foods: a 12-ounce can of coca cola has 140 of its calories from sugar, and a normal sized Snickers bar contains 120 calories from sugar.

But sugar can hide in anything from tomato sauce to salad dressing and peanut butter as well, so it can really rack up even when you don’t realize it. And too much sugar can have some not-so-fun side effects on your health.

Here are some signs you might be consuming too much of the sweet stuff:

1. Weight gain

   There’s lots of evidence that eating too much sugar can cause you to put on some pounds. One study in particular published in BMJ studied that people who ate less sugar lost an average of 1.8 pounds during the course of the study, while people who increased their sugar intake gained 1.7 pounds.

2. Cavities

   Ever hear a parent tell a child they can’t have a lollipop because it’ll rot their teeth? There’s truth to this. While there are numerous studies done on this, like this study, published in the Journal of Dentistry: Researchers found that drinking just 1–2 sugar-sweetened beverages a day was linked to a 31 percent higher risk of cavities. On the same, but a more positive note, scaling back your sugar intake to less than 10 percent of your daily calories lowers your tooth decay risk, according to a study published in the Journal of Dental Research.

3. Bloat and digestion issues

   If you’re eating a lot of sugar and then feeling kinda puffy or not able to digest food well, then you might have a fructose intolerance. Three out of four people with unexplained gastrointestinal symptoms (including bloating) had fructose intolerance in a University of Iowa study.

4. Fogginess/headaches

   Ever hear someone say they have a sugar hangover? That’s a real thing! A UCLA study showed how eating too much fructose can slow the brain, which can cause that foggy feeling, and even affect your memory and learning. Additionally, the rise and drops in glucose can trigger headaches (similar to how it can cause energy highs and lows).

5. Depression

   If you’re feeling particularly blue lately, you might be able to chalk that up to too much sugar. A long-term study found that sugar intake from sweet food and beverages was linked with depressive symptoms. Additionally, a study published in the Journal Public Health Nutrition found that eating processed pastries, such as muffins, doughnuts, and croissants (which are filled with added sugar) resulted in more depressive symptoms.
