People eat corn starch for several reasons including medical, nutritional, psychological, and sensory factors. Medically, cornstarch is used as a slow- release carbohydrate source to help manage blood sugar levels in conditions like type 1 diabetes and glycogen storage diseases. Nutritionally, some people, particularly women during pregnancy or with iron or zinc deficiencies, may crave cornstarch due to a condition called pica—a craving for non-food substances often linked to mineral deficiencies. Psychologically, eating cornstarch can provide comfort or help manage stress for some individuals. Additionally, some enjoy the sensory experience of its smooth, powdery texture. However, cornstarch contains mostly carbohydrates with little nutritional value and consuming it in large amounts or raw can lead to health issues like digestive problems. In summary:

• Medically used for slow blood sugar release in certain diseases.
• Craved in pica due to mineral deficiencies (iron, zinc).
• Psychological comfort or stress relief.
• Sensory appeal of texture.
• Health risks if consumed excessively or raw, offering no significant nutrients.
