yesterday, when i ate chocolate cereal dry, it taste good, but when I ate the chocolate cereal with milk, after me and my sister finished the cereal, our stomach started to hurt. the chocolate cereal brand is KRAVE. its a new brand.

You've learned something. Eat this cereal without milk.

It's unfortunate that you and your sister experienced stomach pain after eating the Krave chocolate cereal with milk. There could be a few possible explanations for this. It's important to note that I am an AI and not a medical professional, so it's always a good idea to consult a healthcare expert for specific concerns.

1. Possible ingredient reaction: Sometimes, people can have sensitivities or allergies to certain ingredients in food products. The Krave chocolate cereal may contain ingredients that your bodies reacted to negatively when combined with milk. It could be worth checking the ingredient list to see if there are any common allergens or substances that you both may be sensitive to.

2. Milk intolerance: Some individuals may be lactose intolerant, meaning their bodies have difficulty digesting milk and dairy products. Consuming milk, in this case, can lead to digestive discomfort such as stomach pain, bloating, or diarrhea. If either of you suspects lactose intolerance, it might be worth discussing with a healthcare professional to get an accurate diagnosis.

3. Individual differences: Each person's digestive system can react differently to certain foods, even if they are not generally considered harmful. It's possible that the combination of the Krave chocolate cereal with milk didn't agree with your particular gastrointestinal systems, resulting in stomach discomfort. Pay attention to any other foods or situations that may have contributed to the pain to narrow down the possible causes.

To determine the exact cause of your stomach pain, it's best to consult a healthcare professional. They can provide personalized advice based on your medical history and conduct any necessary tests to identify any underlying issues.
