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. [53] Kelp in its natural form has not yet been demonstrated to have such ...
Kombu contains extremely high levels of iodine. While this element is essential for normal growth and development, the levels in kombu can cause overdoses; it has been blamed for thyroid problems after drinking large amounts of soy milk in which kombu was an additive. [19] It is also a source of dietary fiber.

Natural food sources of iodine include seafood which contains fish, seaweeds, kelp, shellfish and other foods which contain dairy products, eggs, meats, vegetables, so long as the animals ate iodine richly, and the plants are grown on iodine-rich soil. [114] [115] Iodised salt is fortified with potassium iodate, a salt of iodine, potassium, oxygen.
Ascophyllum nodosum is an autotroph, meaning that it makes its own food by photosynthesis, like other plants and algae. The air bladders on A. nodosum serve as a flotation device, which allows sunlight to reach the plant better, aiding photosynthesis. [6] Epiphytic red algae on knotted wrack at Roscoff, France
The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. [6] Most edible seaweeds are marine algae whereas most freshwater algae are toxic. Some marine algae contain acids that irritate the digestion canal, while others can have a laxative and electrolyte-balancing effect. [7]
[21] [23] The kelp industry picked up again for iodine production in 1845, and alginate (a thickening agent) production in the early 1900s, which reinvigorated kelp harvest. [ 21 ] Global production of seaweed fertilizer largely phased out when chemical fertilizers were developed in the 1920s, due to the cheaper production cost.
