Seaweed is rich in nutritional value and is known as "the treasure of the sea". Because of its low calorie and strong satiety, it has become a good helper to lose weight. Li Zhan, a nutritionist at Tainan Municipal Hospital, said that seaweed growing in seawater contains more natural inorganic elements than plants on land, among which sodium, potassium, iron, calcium and magnesium are the highest, and it also contains many essential amino acids, vitamins, minerals and various photosynthetic pigments, such as chlorophyll, phycoerythrin and phycoerythrin, which are beneficial to human health.
Eating seaweed for health care has four advantages.
No. 1 Good, reduce fat accumulation: Fat in human body can be divided into brown adipose tissue and white adipose tissue. Brown adipose tissue will decrease with age. The main function of white adipose tissue is to store excess heat as triglycerides, and the decoupling protein-1(UCP- 1) in adipose tissue can convert excess energy into heat energy and consume it. It was found that fucoidan in brown algae can activate UCP- 1 in white adipose tissue, thus inhibiting fat accumulation.
Second, improve immunity: Studies show that brown algae extract can increase the activity of immune cells such as macrophages and natural killer cells, and improve human immunity.
Third, improve intestinal function: seaweed is rich in dietary fiber, and most of it is water-soluble. After the fiber of seaweed enters the human stomach, it expands due to water absorption, so it is easy to feel full and avoid eating too much food. Seaweed dietary fiber can also promote intestinal peristalsis, help feces discharge, reduce the contact time between intestinal wall and harmful substances in feces, and prevent the occurrence of colorectal cancer.
Fourth, inhibit inflammatory reaction: inflammation is a normal protective mechanism against foreign bacteria, but excessive inflammation may lead to diseases. At present, studies have confirmed that brown algae extract can inhibit inflammatory reaction.
Changes in seaweed cuisine Avoid drinking coffee after eating more.
Nutritionist Zhan Lu said that there are four kinds of algae: green algae, cyanobacteria, red algae and brown algae. Common ingredients are Ulva, kelp, kelp, Sargassum, Undaria pinnatifida, seaweed, seaweed and coral grass. People can make side dishes, soups and desserts according to their personal preferences, such as cold kelp.
However, it is recommended to soak for 2 hours before cooking, and change the water twice during the process. The soaking time should be avoided for more than 6 hours to avoid the loss of water-soluble fiber. Avoid drinking tea and coffee immediately after eating seaweed, so as not to inhibit the absorption of iron in seaweed. In addition, patients with hyperthyroidism should avoid eating seaweed with high iodine content, so as to avoid excessive iodine intake and aggravate the condition.
