Seeds of pumpkin vines. Pumpkin is also called pumpkin and rice melon. It is cultivated all over China. Harvest ripe fruits in summer and autumn, cut melons, collect seeds, remove pulp film, and dry or dry them. When eating, remove the seed shell and call it pumpkin kernel. Sunflower seeds contain β-carotene, which can prevent the cells in the lower layer of human skin from dying.
Nuts are low purine foods, in which the purine content is lower than that of soybeans and most beans. For example, the purine content in walnut is 25mg/ 100g, Brazil nut is 23, hazelnut is 37, while peanut is slightly higher, 79, tofu is 68, soybean is 190, and pork is 150.
Two studies in the United States show that in the long run, eating nuts every day can prevent weight gain and improve metabolic health.
Researchers from the Nutrition Department of Harvard School of Public Health collected health data of 25,000 men and more than 654.38 million women, including a questionnaire on the type and frequency of food intake, which was counted every four years. The results showed that during the follow-up period, 1 serving (about 28g) of nuts or peanuts replaced foods with low nutritional value such as red meat, processed meat, French fries and desserts, which significantly reduced the risk of obesity.
The researchers pointed out that the average annual weight gain of adults is 1 pound (about 0.45 kg). This figure seems small, but after 20 years of accumulation, it is not a small number. Some people think that nuts are high-fat and high-calorie foods and dare not eat more. In fact, eating a little in moderation will help prevent the slow weight gain in adulthood and reduce the occurrence of various diseases related to obesity.
Researchers from the School of Sports and Nutrition Sciences at San Diego State University in California studied the hypoglycemic and weight-loss effects of Brazil nuts. Participants in both groups added 36 grams of pretzels or 20 grams of Brazil nuts with the same calorie and sodium content to their normal diet.
The interval between each test is 48 hours. The results showed that the satiety induced by Brazil nuts was stronger. After 40 minutes of eating, the blood sugar and insulin levels of participants who ate pretzels were significantly higher than those who ate Brazil nuts.
