Are you constantly craving something sweet, searching through the pantry for snacks, or feeling tired and irritable for no obvious reason? Your daily sugar intake could be playing a role. Added sugars are now found in many common foods, including sauces, flavored yogurts, cereals, drinks, protein bars, baked goods, and specialty coffees. Unlike naturally occurring sugars in whole fruits and dairy, added sugars can be easier to consume in large amounts without realizing it.

Reading food labels can help, especially the section showing added sugars. Sugar can also appear under many different names, including ingredients ending in “-ose,” as well as syrups, concentrates, nectars, and other sweeteners. Eating too much added sugar may contribute to several noticeable changes in the body. But how do you know when your sweet tooth has become a warning sign? There are eight possible signs that may suggest your sugar intake deserves a closer look—and some of them may surprise you.
