Nutritional Facts of Pumpkin Seeds:What is the nutritional profile of pumpkin seeds per 100 grams?
Q: What is the nutritional profile of pumpkin seeds per 100 grams?
A: According to the USDA FoodData Central, 100 grams of raw pumpkin seeds (hulled, also known as pepitas) provide approximately 559 calories, 30 grams of protein, 49 grams of total fat (mostly unsaturated), and 11 grams of dietary fiber. They are rich in minerals such as magnesium (592 mg), phosphorus (1233 mg), and zinc (7.8 mg). The same source notes that pumpkin seeds are a good source of iron, potassium, and B vitamins. This nutrient density makes them a valuable addition to a balanced diet, though portion control is advised due to their high calorie content.
Q: How much magnesium and zinc do pumpkin seeds contain?
A: The USDA FoodData Central reports that 100 grams of raw pumpkin seeds contain 592 mg of magnesium and 7.8 mg of zinc. Magnesium is essential for muscle and nerve function, blood sugar regulation, and bone health, while zinc supports immune function, wound healing, and DNA synthesis. A 30-gram serving provides about 178 mg of magnesium (around 42% of the Daily Value) and 2.3 mg of zinc (about 21% of the DV). The Linus Pauling Institute notes that the zinc in pumpkin seeds is highly bioavailable, making them an excellent plant-based source.
Q: What are the health benefits of the nutrients in pumpkin seeds?
A: Pumpkin seeds are rich in magnesium, zinc, and antioxidants, which contribute to various health benefits. According to the Harvard T.H. Chan School of Public Health, these nutrients support immune function, heart health, and blood sugar regulation. Magnesium helps lower blood pressure, while zinc is crucial for immune defense. The antioxidants, including vitamin E and phytosterols, may reduce inflammation and protect against chronic diseases. Additionally, the high fiber content promotes digestive health. However, the school advises moderation due to the seeds' high calorie density.
Q: Are pumpkin seeds a good source of plant-based protein?
A: Yes, pumpkin seeds are an excellent source of plant-based protein. The USDA FoodData Central states that 100 grams of raw pumpkin seeds contain about 30 grams of protein, which is higher than most nuts and seeds. A 30-gram serving provides roughly 9 grams of protein. This protein includes all essential amino acids, though it is limited in lysine, according to the FAO. For a complete protein profile, pumpkin seeds can be combined with legumes or grains. Their protein content makes them a valuable food for vegetarians and vegans.
Q: What is the fat composition of pumpkin seeds?
A: Pumpkin seeds are primarily composed of healthy unsaturated fats. The USDA FoodData Central reports that 100 grams of raw pumpkin seeds contain 49 grams of total fat, of which about 8.7 grams are saturated, 14.5 grams are monounsaturated, and 20.4 grams are polyunsaturated fats. The polyunsaturated fats include omega-6 and omega-3 fatty acids, though the ratio is skewed toward omega-6. These fats support heart health and provide energy. The high fat content also contributes to the seeds' calorie density, so moderation is recommended.
