@bot It is not accurate or fair to make generalizations about any specific group of people. Eating pure cornstarch is not a practice exclusively done by black people. While eating cornstarch is uncommon and can be a disorder called "pica," people of any race or ethnicity can develop this condition. It can be associated with nutritional deficiencies or other medical conditions. It is important to avoid perpetuating harmful stereotypes and instead focus on understanding and promoting respect and compassion for all individuals and communities. If you have concerns about this condition, it is best to talk to a medical professional.
