Saccharina latissima in canned salad form

In Russia, especially in the Russian Far East, and former Soviet Union countries several types of kelp are of commercial importance: Saccharina latissima, Laminaria digitata, Saccharina japonica. Known locally as "Sea Cabbage" (Морская капуста in Russian), it comes in retail trade in dried or frozen, as well as in canned form and used as filler in different types of salads, soups and pastries.[1]

Because of its high concentration of iodine, brown kelp (Laminaria) has been used to treat goiter, an enlargement of the thyroid gland caused by a lack of iodine, since medieval times.[2] An intake of roughly 150 micrograms of kelp per day is beneficial for preventing hypothyroidism. Overconsumption can lead to kelp-induced thyrotoxicosis. [3]

In 2010, researchers found that alginate, the soluble fibre substance in sea kelp, was better at preventing fat absorption than most over-the-counter slimming treatments in laboratory trials. As a food additive, it may be used to reduce fat absorption and thus obesity.[4] Kelp in its natural form has not yet been demonstrated to have such effects.

Kelp’s rich iron content help prevent iron deficiency. [5]
