We can look at the heat of melon seeds. We often eat sunflower seeds, watermelon seeds and pumpkin seeds. 100g sunflower seeds have about 600 calories, watermelon seeds about 556 calories and pumpkin seeds about 574 calories. They are all high-calorie households and rich in oil, which can be used to extract oil. Although we usually eat small grains, there is nothing on them. It tastes delicious (in fact, it is only fragrant when there is more oil), but in fact, eating a few more will make you a little nauseous and your appetite will drop a little. This is because the intake of oil is a little too much, which is the result of gastrointestinal advice. A bowl of rice is about 1 16 calories, and 100g pork belly is about 349 calories. Eating 100g melon seeds is equivalent to eating five bowls of rice, and the calories of pork belly are three times. My friend who just ate melon seeds all over the floor is a little dizzy and getting fat.
But eating melon seeds properly every day is actually very beneficial to human health. Although melon seeds are high in calories and rich in oil, we can control our intake. For example, the Dietary Guide recommends that nuts (including melon seeds/plant seeds) be about 10g (about 7-8 almonds) per day, which can be ignored, but nuts are rich in nutrition, and only 10g can supplement many beneficial ingredients for us.
The fat in nuts can't be compared with the "saturated fat" and "trans fatty acids" that we usually eat from fat, fried food and puffed snacks. Most of the fat in nuts belongs to "unsaturated fatty acids". Although saturated fatty acids are not directly harmful to human body, they are easy to cause obesity and hyperlipidemia due to excessive energy intake; Trans fatty acids are a threat to health, which will increase the content of "low density lipoprotein", which is a kind of "bad cholesterol", which will increase the cholesterol circulation in the blood, increase the cholesterol concentration, induce hyperlipidemia, and accumulate on the blood vessel wall, increasing the incidence of atherosclerosis, coronary heart disease and other diseases.
Unsaturated fatty acids have many effects on human body, such as maintaining cell membrane fluidity, synthesizing hormones, regulating sebaceous gland secretion, protecting skin, etc. Constitute retina and cerebral cortex, anti-inflammatory, anti-allergic, regulating blood lipid and endocrine. Most of the fatty acids in nuts are omega-6 series fatty acids, which can maintain the composition of cell membrane and regulate the secretion of sebaceous glands and hormones, as mentioned above. Proper omega-6 can also improve blood lipids and increase the number of high-density lipoprotein. However, omega-6, omega-3, omega-9 and other fatty acids * * * are metabolized by the same enzyme, so if the ratio between them is not balanced, it may lead to imbalance in the body, but it will cause some unfavorable situations to the body. For example, excessive intake of omega-6 may increase obesity and cellular inflammation. Therefore, you must not eat more nuts!
Proper intake of nuts is beneficial to the human body. They are rich in various minerals, fat-soluble vitamins, protein, carbohydrates, rich dietary fiber, and unsaturated fatty acids mentioned above. Don't eat too much, and don't chew all over the floor during holidays and Chinese New Year chats. Of course, the body can adjust itself occasionally, but if you chew nuts too often, obesity will wait for us not far away.
