Pumpkin Seed - Diabetes

    Most of the evidence we've seen about pumpkin seeds and prevention or treatment of diabetes has come from animal studies. For this reason, we consider research in this area to be preliminary. However, recent studies on laboratory animals have shown the ability of ground pumpkin seeds, pumpkin seed extracts, and pumpkin seed oil to improve insulin regulation in diabetic animals and to prevent some unwanted consequences of diabetes on kidney function. Decrease in oxidative stress has played a key role in many studies that show benefits of pumpkin seeds for diabetic animals.

    Antimicrobial Benefits

    Pumpkin seeds, pumpkin seed extracts, and pumpkin seed oil have long been valued for their anti-microbial benefits, including their anti-fungal and anti-viral properties. Research points to the role of unique proteins in pumpkin seeds as the source of many antimicrobial benefits. The lignans in pumpkin seeds (including pinoresinol, medioresinol, and lariciresinol) have also been shown to have antimicrobial—and especially anti-viral— properties. Impact of pumpkin seed proteins and pumpkin seed phytonutrients like lignans on the activity of a messaging molecule called interferon gamma (IFN-gamma) is likely to be involved in the antimicrobial benefits associated with this food.

    Cancer-Related Benefits

    Because oxidative stress is known to play a role in the development of some cancers, and pumpkin seeds are unique in their composition of antioxidant nutrients, it's not surprising to find some preliminary evidence of decreased cancer risk in association with pumpkin seed intake. However, the antioxidant content of pumpkin seeds has not been the focus of preliminary research in this cancer area. Instead, the research has focused on lignans. Only breast cancer and prostate cancer seem to have received much attention in the research world in connection with pumpkin seed intake, and much of that attention has been limited to the lignan content of pumpkin seeds. To some extent, this same focus on lignans has occurred in research on prostate cancer as well. For these reasons, we cannot describe the cancer-related benefits of pumpkin seeds as being well-documented in the research, even though pumpkin seeds may eventually be shown to have important health benefits in this area.

    Possible Benefits for Benign Prostatic Hyperplasia (BPH)

    Pumpkin seed extracts and oils have long been used in treatment of Benign Prostatic Hyperplasia (BPH). BPH is a health problem involving non-cancer enlargement of the prostate gland, and it commonly affects middle-aged and older men in the U.S. Studies have linked different nutrients in pumpkin seeds to their beneficial effects on BPH, including their phytosterols, lignans, and zinc. Among these groups, research on phytosterols is the strongest, and it centers on three phytosterols found in pumpkin seeds: beta-sitosterol, sitostanol, and avenasterol. The phytosterols campesterol, stigmasterol, and campestanol have also been found in pumpkin seeds in some studies. Unfortunately, studies on BPH have typically involved extracts or oils rather than pumpkin seeds themselves. For this reason, it's just not possible to tell whether everyday intake of pumpkin seeds in food form has a beneficial impact on BPH. Equally impossible to determine is whether intake of pumpkin seeds in food form can lower a man's risk of BPH. We look forward to future studies that will hopefully provide us with answers to those questions.

      Pestki z Dyni

    Pestki dyni, oprócz kwasów tłuszczowych, zawierają też mnóstwo witamin i minerałów. Witaminy obecne w pestkach dyni, to: witamina E, witamina B1, witamina B2, witamina B6, witamina A, witamina C oraz witamina D. Te małe ziarenka, ze względu na tak duże bogactwo witamin, powinny jak najczęściej pojawiać się w jadłospisie jako urozmaicenie zdrowej diety. Witamina E to w organizmie ważny przeciwutleniacz. Bierze udział w dostarczaniu składników odżywczych do komórek. Poza tym wzmacnia ściany naczyń krwionośnych oraz chroni czerwone krwinki przed przedwczesnym rozpadem. Witamina B1 odgrywa zasadniczą rolę w procesach oddychania tkankowego, głównie w przemianie węglowodanów. Niedobór witaminy B1 może powodować zaburzenia układu nerwowego, krążeniowego oraz pokarmowego.

    Inne witaminy z gruby B zawarte w pestkach dyni to witaminy B2 i B6. Witamina B2 uczestniczy w procesach utleniania w organizmie, współdziała w prawidłowym funkcjonowaniu układu nerwowego, a wraz z witaminą A bierze udział w prawidłowym funkcjonowaniu błon śluzowych, dróg oddechowych, nabłonka naczyń krwionośnych i skóry. Witamina B6 natomiast ułatwia rozkład aminokwasów, uczestniczy w przemianie tłuszczów i cukrów, tworzeniu enzymów, hormonów, hemoglobiny i prostaglandyn – hormonów, które regulują procesy fizjologiczne organizmu. Poza tym zawarta w pestkach dyni witamina B6 umożliwia magazynowanie energii i usprawnia funkcjonowanie układu nerwowego.
