Porphyra can't be eaten with persimmon, because tannic acid contained in persimmon can form sediment with protein and calcium salt in laver, which will stimulate our stomach and cause diseases. Such as nausea and constipation.

Second, seaweed can't be eaten with tea.

Tea contains a large amount of tea tannin, which is easy to combine with protein in laver to form massive protein tannic acid, which is difficult to digest and absorb, leading to constipation. Similarly, ingredients containing too much tannic acid should not be eaten with laver.

Pay attention to taboos:

First, don't eat too much.

The iodine content in seaweed is relatively high. For iodine-deficient areas, eating seaweed often can supplement iodine. For areas where iodine is not deficient, eating a lot of seaweed at one time or eating too much seaweed often will increase the possibility of excessive iodine intake. China Nutrition Society suggested that the recommended daily intake of iodine is 120 micrograms, and the maximum tolerable intake is 600 micrograms. 100 gram of laver contains 4323 micrograms of iodine, and the recommended amount is 2~3 grams per day.

Second, prevent eating desiccant by mistake.

There is desiccant in the packaging of seaweed products, so pay special attention to it. If the desiccant package is damaged, do not eat seaweed. Desiccant should not be eaten, played or soaked in water; Do not open the desiccant bag to avoid burning skin or eyes. If you eat or get into your eyes by mistake, please rinse with plenty of water first and consult a doctor.
