Kelp! I need somebody’s Kelp! Not just anybody’s Kelp!

What is kelp?

It is a large type of brown seaweed. Around the UK there is Oarweed and Sugar Kelp. Kelp is a type of seaweed and algae that can be found in all of the world’s oceans. It grows at or below the low-tide level on the rocky seabed and extends to depths as far as sunlight can penetrate. Seaweed doesn’t have a vascular system like other plants, but all parts of the kelp absorb the nutrients and gases that it needs to grow from the water in which it is immersed.

Kelp is important for many species of fish and crustaceans to survive some such as rockfish use it for shelter whereas sea snails will feed off small particles that get caught up in the kelp forests. Even mammals such as sea otters use kelp to protect their eggs because the kelp is so thick that water currents struggle to push through. Kelp is fast growing so even though it is harvested by humans it tends not to be in danger of being over-harvested.

Kelp is very commonly used by humans in vitamins and soaps however most people don’t know that kelp derived products can be found in ice cream, toothpaste and even beer. Kelp contains high concentrations of iodine, making it especially useful in treating a condition of the thyroid gland caused by lack of iodine. It is also included in medicines that are used to treat tuberculosis, arthritis, colds, influenza and some infections.
