The Nutritional Science Behind Pumpkin Seeds in Shell

Introduction Pumpkin seeds are a superfood, but their whole form — pumpkin seeds in shell — is more nutritionally rich. These crunchy seeds are rich in bioactive compounds, essential minerals, dietary fibre, and antioxidants, all of which contribute to overall health. Scientific research has focused on pumpkin seeds (from Cucurbita pepo, Cucurbita maxima, and other species) for their potential to promote cardiovascular, metabolic, and immune health. When consumed with their shells, the nutritional and functional benefits are even greater. What Are Pumpkin Seeds in Shell? Pumpkin seeds in shell are whole seeds harvested from pumpkins, retaining their white, fibrous outer coating (the hull). Inside the shell lies the green kernel, known as a pepita, which is the part most commonly consumed when dehulled. Unlike shelled seeds, pumpkin seeds in the shell are less processed, preserving their natural nutrients and dietary fibre. This makes them an ideal snack for those seeking a balance between taste, texture, and science-based nutrition. Scientific Nutritional Composition of Pumpkin Seeds in Shell Macronutrient Profile (per 1 ounce / 28 g serving, roasted) Key Micronutrients Phytochemicals and Bioactive Compounds Health Benefits of Pumpkin Seeds in Shell by Science 1.

When consumed with the shell, the added dietary fibre can further reduce cholesterol absorption in the gut. 2. Digestive Health and Gut Function The fibrous hull of pumpkin seeds in shell acts as a natural prebiotic, feeding beneficial gut bacteria and improving intestinal motility. 3. Immune System Support Zinc and iron are both essential for immune cell production and function. 4. Antioxidant and Anti-Inflammatory Effects Pumpkin seeds are rich in vitamin E, phenolic compounds, and flavonoids, all of which neutralise free radicals and reduce oxidative stress — a major contributor to chronic diseases. 5.
