Cultural background plays a significant role in determining dietary choices. Influences such as traditions, religious beliefs, and local food availability shape what individuals consider acceptable or desirable to eat. For instance, some cultures emphasize plant-based diets, while others may incorporate more animal products. Additionally, social norms within a culture can dictate portion sizes and eating patterns, such as communal meals. Understanding these influences helps professionals provide culturally relevant dietary recommendations, enhancing adherence to nutritional plans.
