If the soaking time is too long, the nutrients in kelp will dissolve in water, and the nutritional value will decrease.

Kelp is best mixed with vinegar, which can soften kelp. Try mixing kelp with vinegar. Seaweed soup with ice cubes can highlight the sour taste of vinegar and make the taste more refreshing.

Don't drink tea or eat sour fruit immediately after eating kelp, because kelp is rich in iron, and the above two foods will hinder the absorption of iron in the body.
