What to do if the kelp cannot be boiled

　　There are always various health-preserving ingredients on the table, and kelp is the "low-key champion" among them. It is not only affordable, but also rich in iodine, dietary fiber and various minerals. It is the first choice for many people to make soups and salads. But many people have encountered a headache: Why is the kelp always not boiled and hard and tough to chew? Some people even asked: Since cooking is troublesome, is it okay to just eat it raw? Today, we will explain everything from life tips to medical perspectives at once.

What to do if the kelp cannot be boiled

　　1. Rice water + soaking method

　　Soaking dried kelp in rice water not only removes surface impurities, but also allows the kelp to absorb water and expand faster, making it softer. Generally, it can be soaked for 4-6 hours. Remember not to soak it for too long, otherwise the nutrients will be lost.

　　2. Add vinegar or baking soda

　　When boiling kelp, adding a few drops of white vinegar or a pinch of baking soda can destroy the fiber structure in the kelp and make it soft quickly. At the same time, it can remove the fishy smell and improve the freshness, making the soup clearer.

　　3. Dry steaming and softening method

　　Put the dried kelp into a steamer and steam it for 30 minutes, then soak it in water overnight. The kelp processed in this way is not only easy to rot, but also has a moderately crisp and tender texture. It is delicious whether it is stewed in soup or served cold.

　　Remember: kelp does not get softer the more you cook it, but will harden if cooked for too long. It is recommended to add it 10-15 minutes before the soup is ready to retain nutrients and maintain the ideal taste.

Nutritional value of kelp

　　1. Rich in minerals, iodine supplement strengthens bones

　　Kelp is a natural "iodine supplementer". It is rich in iodine, which can meet the body's thyroid hormone synthesis needs and prevent iodine deficiency diseases.； It is also rich in calcium, phosphorus, magnesium and other minerals. The calcium content is close to that of milk. When combined with vitamin D intake, it can promote bone calcification and help bone health. It is suitable for people of all ages.

　　2. Rich in dietary fiber, promotes intestinal health

　　The high content of soluble and insoluble dietary fiber in kelp can promote intestinal peristalsis, increase stool volume, and effectively relieve constipation.； It can also absorb excess fat and harmful substances in the intestines, reduce cholesterol absorption, help regulate blood lipids, and also has a positive effect on maintaining the balance of intestinal flora.

　　3. Contains unique biologically active substances

　　Kelp contains special ingredients such as alginic acid and fucoxanthin. Alginic acid can bind heavy metal ions and promote their excretion, reducing the accumulation of toxins in the body.； Fucoxanthin has antioxidant effects, helps scavenge free radicals, and studies have shown that it may assist in regulating metabolism and has multiple health benefits.

Precautions for eating kelp

　　1. Control the amount of food consumed to avoid excessive iodine

　　Kelp has a high iodine content. It is recommended that adults consume no more than 50 grams per day (about 5-10 grams of dried product). Excessive intake may lead to hyperthyroidism. In particular, patients with thyroid disease need to follow the doctor's advice and avoid blind consumption to avoid aggravating the condition.

　　2. Thoroughly soak and clean hair to remove harmful substances

　　Dried kelp needs to be soaked in clean water for 4-6 hours, changing the water 2-3 times during this period to remove residual salt, sediment and possible arsenic and other harmful substances on the surface.； Wash thoroughly after soaking, make sure to cook it thoroughly when cooking, and avoid eating it raw or cold to reduce the risk of gastrointestinal discomfort.

　　3. Special groups should eat with caution

　　People with spleen and stomach deficiency (usually bloating, diarrhea, and chills) may experience aggravated discomfort after eating, so they need to try a small amount or use it with warm ingredients such as ginger and pepper.； Pregnant women, lactating women and people with renal insufficiency need to control their consumption under the guidance of a doctor because kelp contains high potassium and phosphorus.
