For years, it has been asserted that consuming carrots enhances night vision and that sugar induces hyperactivity in children. Recent study indicates that these longstanding beliefs, along with various other dietary myths, are really erroneous.
From the truth about cholesterol in eggs to the safety of microwaving meals, science is shedding new light on what we should—and shouldn’t—believe when it comes to nutrition.
