Squash (Cucurbita pepo) is a plant originating from North America (Mexico), grown in Poland. Pumpkin flesh (pulp cucurbitae) and pumpkin seeds (Semen cucurbitae recens) are used as a source of food. The pulp is a rich source of unsaturated fatty acids (e.g. Acid, linoleic acid, linolenic acid, oleic acid), and phytosterols, vitamins (pro-vitamin A, B1, B2, C, E, PP), minerals (cobalt, magnesium, copper, potassium, calcium , iron), sugars and protein and fibre. Fresh seeds contain approx. 50% oil, phytosterols, phytates, cucurbitacins, triterpenes, peponozyd and vitamins and minerals. The oil contains unsaturated fatty acids (such as fatty acids: linoleic acid, linolenic acid, oleic acid). The positive effect of pumpkin oil was found in the sports supplementation and in the prophylaxis of prostate cancer, as well as its effect on LDL cholesterol and heart. Consuming affects the maintenance of health, or even improving it. Both the pulp and pumpkin seeds and oil are used in the household, as well as in dietary supplements (it is a component of a nutritional and functional supplements).
