Kelp or seaweed also called a “miracle plant” is a green marine plant that is used to enhance flavors in a variety of dishes, from salads and soup to meat and seafood dishes. In Japan, for example, seaweed makes up 25% of all food in the diet. Today, seaweed is also a popular ingredient in some skincare and weightloss products.
Seaweed Classification: In general, seaweed is classified according to its color which is brown, red green, and blue-green.
Seaweeds Available Form: Seaweed is usually sold commercially in dried form.
Seaweed Varieties: There are more than 2,500 varieties of seaweed which include everything from the algae that forms on ponds to kelp and other marine plants with long stems and leaves. A variety of kelp known as California kelp is not as good product for nutritional purposes; however, it is useful as a fertilizer, to enrich soil.
Common Kinds of Kelp:
- Kombu, a type of kelp that is most widely sold seaweed in Japan. Kelp is light brown in color and usually available as flakes or in powder form. It is used to flavor soup stocks.
- Wakame, another type of kelp, it is highly sought after for bean-curd soup or salads. Wakame is long hard strips that can be softened with water.
- Nori or Laver is a commonly consumed red seaweed. In Japan, nori is used to wrap sushi, and in Wales it was traditionally made into flat breads.
Important thing to know about Seaweeds:
- Some varieties of seaweeds are up to 30 times higher in minerals than land vegetables, which is affected by depleted nutrient levels in our soils.
- The mineral content of various types of seaweed differs, but most provide calcium, copper, iron, potassium, and magnesium. Some supply beta carotene, a precursor of vitamin A; the levels vary with the cooking method.
- Kelps correct mineral deficiencies. Sprinkling a little kelp on your food (about a teaspoonful twice a day) will provide both salt and vital trace minerals.
