What modifications can be made to improve the nutritional benefits of pastry?

To improve the nutritional benefits of pastry, consider substituting refined flour with whole grain or alternative flours like almond or oat flour, which offer more fiber and nutrients. Incorporating healthier fats, such as olive oil or avocado oil, instead of butter can enhance the lipid profile. Additionally, adding nutrient-dense ingredients like seeds, nuts, or vegetables can boost vitamins and minerals while maintaining flavor. Finally, reducing sugar or using natural sweeteners can further enhance the healthfulness of the pastry.
