You probably know that candy bars and soda are loaded with sugar.
What is easy to miss is how much hides in everyday foods that look perfectly healthy. Your body often spots the overload before you do.
According to the American Heart Association, adult women should keep added sugar under 25 grams a day and men under 36 grams. A flavored yogurt, a jarred pasta sauce and a single sports drink can push you past that line before dinner.
The Harvard T.H. Chan School of Public Health notes that less obvious sources, like breakfast cereals and yogurt, add significantly to our intake alongside sweet drinks and desserts.

Below are seven signs that your intake may be higher than you think. Some you would normally blame on stress, aging or a bad night's sleep.
Energy crash about 90 minutes after you eat
A sugary meal drives blood glucose up fast and then down just as fast. The crash triggers cortisol and adrenaline, which leaves you shaky, foggy and ready for a nap. If you feel wiped out an hour or two after eating, the meal may be the cause.
Constant cravings for something sweet
Sugar activates the brain's dopamine reward pathway much like other rewarding stimuli. Each spike and crash trains the brain to ask for another hit. Cravings tend to grow louder the more often you give in.
Breakouts you cannot explain
Diets high in refined sugar raise insulin and inflammatory markers. Both push oil glands to produce more sebum and feed the pathway that leads to acne. Dermatology research consistently links high-glycemic diets with more breakouts in teens and adults.

Trouble focusing and thinking clearly
Glucose swings strain the hippocampus, the brain region central to memory and concentration. Work from the University of Sydney and other groups has linked diets high in fat and sugar with poorer memory and slower thinking, even in young adults.
Restless nights and lighter sleep
Added sugar, especially from sweet drinks, is tied to shorter and more disturbed sleep. One large Korean study of more than 118,000 adolescents found that those drinking soft drinks five or more times a week were far more likely to sleep under six hours.
Low mood and quicker irritability
A 2024 meta-analysis of 40 studies with about 1.2 million participants, published in Frontiers in Nutrition, found that higher sugar intake was linked with a 21 percent higher risk of depression. The association was stronger in women than in men.
Weight creeping on around your middle
Visceral fat, the kind stored deep in the belly around your organs, is especially responsive to added sugar. Long-term research has found that daily consumers of sugary drinks gain more of this fat than non-consumers over several years, even without eating more calories overall.

If several of these signs sound familiar, start with the nutrition label on the foods you buy most often.
As we have covered in our guide to the daily sugar limit, most Americans still cross the AHA ceiling of 25 grams for women and 36 grams for men on an average day.
