Why is constipation most common in western countries than is less common in Mediterranean?

Constipation is more common in Western countries primarily due to dietary habits, particularly lower fiber intake from processed foods and a higher consumption of animal products. In contrast, Mediterranean diets typically emphasize fruits, vegetables, whole grains, and legumes, which are rich in fiber and promote regular bowel movements. Additionally, lifestyle factors such as lower physical activity levels in Western countries may contribute to digestive issues. These combined dietary and lifestyle differences lead to higher rates of constipation in Western populations.
