The Benefits of Pumpkin seedsAccording to the research, pumpkin seeds contain many substances which useful for our healthy.
In seeds of Parang pumpkins found a few rare amino acid, such m-karboksifenilalanina, pirazoalanina, amino butirat acid, etilasparagina, and strulina. Red seeds pumpkins contain mineral Zn (Zinc) and Mg (Magnesium) which are very important for our organ of reproduction health, include prostate gland. Then also contain prominent fat such as linoleum acid.
Health benefits of pumpkin seeds
  • Crunchy pumpkin seeds are high in calories, about 559 calories per 100 g. In addition, they are packed with fiber, vitamins, minerals, and numerous health promoting antioxidants.
  • Their high caloric content mainly comes from protein and fats. On the positive side, the nuts are especially rich in mono-unsaturated fatty acids (MUFA) like oleic acid (18:1) that helps lower bad LDL cholesterol and increase good HDL cholesterol in the blood. Research studies suggest that Mediterranean diet, which is rich in monounsaturated fatty acids helps to prevent coronary artery disease and strokes by favoring healthy blood lipid proile.
  • The seeds contain good quality protein. 100 g seeds provide 30 g or 54% of recommended daily allowance. In addition, the seeds are excellent source of amino acids tryptophan and glutamate. Tryptophan is converted in to serotonin and niacin. Serotonin is a beneficial neuro-chemical often labeled as nature's sleeping pill. Further, tryptophan is precursor of B-complex vitamin, niacin (60 mg of tryptophan = 1mg niacin).
  • Glutamate is required in the synthesis of γ-amino butyric acid (GABA). GABA, an anti-stress neurochemical in the brain, helps reducing anxiety, nervous irritability, and other neuroses conditions.
  • Pepitas are very good source of anti-oxidant vitamin E; contain about 35.10 mg of tocopherol-γ per 100 g (about 237% of RDA). Vitamin E is a powerful lipid soluble antioxidant. It prevents tissue cells from the free radical mediated oxidant injury. Thus, it helps maintain the integrity of mucus membranes and skin by protecting from harmful oxygen free radicals.
  • Pumpkin kernels are also excellent source of B-complex group of vitamins such as thiamin, riboflavin,niacin, pantothenic acid, vitamin B-6 (pyridoxine) and folates. These vitamins functions as co-factors for enzymes during cellular substrate metabolism in the body. In addition, niacin help reduce LDL-cholesterol levels in the blood. Along with glutamate, it enhances GABA activity inside the brain, which in turn help reduce anxiety and neurosis.
  • Furthermore, its seeds contain very good levels of essential minerals like copper, manganese,potassium, calcium, iron, magnesium, zinc and selenium. Just as pine nuts, pumpkin seeds are very rich in manganese (provide 4543 mg per 100 g, about 198% of daily-recommended intake), pines are one of the richest sources of manganese. Manganese is an all-important co-factor for antioxidant enzyme,superoxide dismutase. It is therefore, consumption of pumpkin kernels helps body develop resistance against infectious agents and scavenge harmful oxygen free radicals.

Medicinal values of pumpkin seeds.
  • Research studies suggest that pumpkin seeds have DHEA (Di hydro epi-androstenedione) blocking actions. This may be helpful in preventing prostate and ovarian cancers.
  • In addition, experimental studies suggest that certain phytochemical compounds in pumpkin seed oil may have role in prevention of diabetic nephropathy (kidney disease).

Selection and storage
The Benefits of Pumpkin seeds - Pumpkin seeds are available in the stores all around the year. You may find whole seeds (un-hulled), hulled, and roasted seeds displayed in the grocery stores. In the Latin American world, hulled and roasted pumpkin seeds are referred as pepita.

While buying whole seeds look for uniform sized, compact, cream-white, or light yellow color seeds that feel heavy in hand and feature good metallic sound. 
Avoid thin, small sized, shriveled seeds as they yield poor quality kernel. They should be free from cracks, mold, and spots and free of rancid smell. 

Completely un-hulled seeds keep well for few months placed in cool dry place. However, hulled pumpkin kernels deteriorate soon if exposed to warm, humid conditions; therefore, should be placed in an air-seal container and stored inside the refrigerator.
