Some avoid food due to religious rules, like no pork in Islam, or allergies to nuts. Health issues matter too. I think personal choice plays a big role here.

People skip foods due to cultural taboos or vegetarianism for ethics. Allergies also limit them. I’ve seen friends avoid seafood for health reasons.

Certain foods are avoided for medical conditions or ethical stances, like veganism. Tradition influences it too. I feel it’s a mix of factors.
