There are several factors that influence or determine what we eat, including cultural background, personal preferences, dietary habits, budget, availability, and health considerations. Our cultural background can shape our food choices by influencing the types of foods we grew up eating and the flavors we're accustomed to. Our personal preferences and dietary habits also play a role in shaping our food choices like being vegetarian or vegan. Budget and availability can also limit or expand our choices, as can health considerations such as allergies, chronic diseases, and nutrient deficiencies.
