Which is healthier, seaweed or laver?
In the algae family, laver is a dazzling star food. The content of protein and carotene is far ahead, and the content of soluble dietary fiber is also among the best. The soluble dietary fiber content of laver is 2.5 times that of dried kelp, which has many functions such as relieving dryness, promoting intestinal health and preventing constipation. In addition, the contents of various minerals in laver are much higher than its "dear friend" kelp. Therefore, laver made of laver as the main raw material naturally has a lot of nutrition of laver. However, at this point, can you think it is a healthy snack? Didn't you find that seaweed is much more delicious than dried seaweed when you were eating it? Obviously, seaweed will be more crisp and fragrant. Although the main raw material of laver is laver, it is not a kind of dried laver food, and the national standard also makes a clear distinction between them. Dehydrating and drying laver to obtain dried laver. It can be seen that nothing else is added during the production of dried laver, so the raw materials are "single". Laver, on the other hand, is a "gorgeous turn" of laver, which takes laver as raw material, adds seasonings and some food additives for seasoning. Obviously, the ingredients in laver are no longer single, and the nutrition is far less than that of laver.
Is seaweed a gorgeous turn of seaweed?
Yes, seaweed is not as healthy as you think. Laver sounds tall, but the main raw material is the laver we eat every day.
The main reason for the nutrient loss of laver comes from its extra seasonings, mainly salt, soy sauce, monosodium glutamate and sugar. This will really make the taste of seaweed much better than that of dried seaweed, but it will also make the sodium content of seaweed soar rapidly. Some sodium content is as high as 2000 mg/100 g, which is equivalent to 5 g of salt per 100 g of seaweed. What is this concept?
Take the seaweed slices that are usually packaged in the market as an example. Each package contains about 3g of seaweed, so that one package can eat 60mg of sodium. It is normal for many people to eat about 10 packet at a time. Inadvertently, 600mg of sodium was eaten into their stomachs, which was about 1.5g of salt.
The daily salt consumption of adults should not exceed 6 grams, that of children under 5 years old should not exceed 3 grams, and that of children aged 2-3 years old should not exceed 2 grams. In this way, the salt content of 10 laver is not small.
Especially for infants and young children, the daily sodium requirement is much lower than that of adults, and the meals cooked for children are light and seasoned with little or no salt, while laver is like a high-salt "bomb". A high-salt diet will not only burden children's health, but more importantly, it may make children fall in love with heavy tastes and forget to enjoy the original flavor of food, thus delaying the formation of the whole eating habit.
Therefore, it is better to eat less high-salt snacks. In addition to the "hard injury" of salt, seaweed will also add extra ingredients such as sugar and food additives, which will increase the burden on the body and should also be restricted.
The nutrition of laver is beyond imagination
Among many health foods, laver is a very good health food. Porphyra contains 12 vitamins, especially vitamin B 12. Vitamin BB 12 has the functions of activating cranial nerves, preventing aging and memory loss, and improving depression. Porphyra has no calories and is most suitable for middle-aged and elderly people to supplement vitamin B 12. As long as you eat more than a dozen pieces of laver every day, you can supplement 2.4 mg of vitamin B 12 that the human body needs every day. Therefore, when eating breakfast, putting a few pieces of laver on the rice, wrapping the rice ball with a layer of roasted laver and eating a box lunch of laver are all wonderful ways to eat laver.
As the saying goes, people's aging begins with blood thickening. EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in fish can prevent human aging. Porphyra is rich in EPA and DHA, and contains a lot of taurine which can reduce harmful cholesterol. Taurine helps to protect the liver and keep people energetic. The taurine content of 1 laver is 30-35 mg, which is equivalent to the taurine content of 3-4 oysters.
1/3 of laver is dietary fiber. Dietary fiber can keep intestinal health and excrete carcinogens, which is especially beneficial to prevent colorectal cancer.
Modern nutritional research shows that polysaccharides (mucus components) in seaweed have the effect of inhibiting cancer. Porphyra contains trace polysaccharides, and animal experiments have proved that Porphyra has the effect of inhibiting cancer.
Children with heavy seaweed should eat less.
The raw material of laver is laver, which is rich in glutamic acid, so it tastes delicious. Moreover, many seaweed products are added with mushroom juice or mushroom extract, and the free natural nucleotides will bring rich flavor, so it is no wonder that people can't stop eating them. The delicious laver comes from the food itself, and it is rich in important trace elements such as iodine, iron and zinc that teenagers are easy to lack. However, a careful look at the ingredient list shows that the seaweed sold in the market also contains seasonings such as salt and soy sauce, and the taste is salty. Children's eating habits need to be cultivated from an early age. If you start eating this delicious snack too early, it will not only be bad for cultivating healthy eating habits, but also increase the risk of hypertension and related diseases. It is recommended to eat less for children.
