Some people really love chewing ice, it’s true. But if you find yourself craving the cold stuff it might be a sign of anemia. A 2016 study in the Journal of the American Association of Nurse Practitioners concluded that doctors should ask patients if they crave ice as it’s a sign of iron deficiency. Ice cravings are a form of pica—a desire to eat non-food items like dirt and laundry soap—and are linked to low iron levels. The researchers hypothesized it might be because chewing the ice might temporarily increase blood flow to the brain, counteracting the slowdown caused by iron deficiency.
If you find yourself constantly reaching for chocolate—one of the most popular food cravings—you may be depressed and trying to self-medicate with the sweet stuff. A survey of more than 13,000 people found that those who ate dark chocolate during a 24-hour period were 57 percent less likely to report symptoms of depression. In addition, chocolate contains magnesium and theobromine, two compounds shown to reduce levels of stress hormones and promote muscle relaxation. Treatment for depression can be complicated, but these 10 foods can naturally improve your mood.
