Since ancient grampian electronics times, the algae have been part of the traditional diet of coastal communities. Today are still very popular in East Asia, especially in Japan, China and Korea, but are not widely accepted in Europe. Recently, algae have aroused the public interest to be a very nutritious food with numerous health benefits. Here are some facts. Types of Algae Algae mainly inhabit the saltwater oceans and seas, and like terrestrial plants need sunlight grampian electronics to thrive. grampian electronics There are over ten thousand varieties of algae, many of them edible. Nori is a red alga whose consumption is quite common. In Japan, nori seaweed used to wrap sushi. Also known as laver sloke in Scotland and in Wales, where traditionally added to a type of unleavened bread. Kombu and wakame are two types of brown algae that are frequently used in the Far East to extol the flavor of stews and soups. Green algae as "sea lettuce" and "sea grampian electronics grass" that occur on the coasts of Britain, Ireland and Scandinavia, can be eaten raw in salads or cooked in soup. Other edible seaweed are hijiki, grampian electronics wrack, "sea spaghetti", dulse and Irish moss. Seaweeds are often traded dry. Nutritional content A recent study analyzed the levels of nutrients in various edible seaweed, comparing a typical serving (8 g of dried seaweed) with a recommended daily allowance and common foods. Mineral Algae are rich in minerals and trace elements absorbing the sea. Calcium and iron tend to accumulate at higher levels in the algae in terrestrial plants. For example, a portion of 8 g of dried kombu seaweed provides more calcium than a cup of milk, and a portion of dulse contains more iron than beef steak 100 g (although the body can assimilate it worse). Algae also provide large amounts of iodine, which is essential for the functioning of the thyroid. However, the German Federal Institute for Risk Assessment has issued grampian electronics a warning about certain varieties of algae with excessive levels of iodine and recommended setting maximum limits for insurance products throughout the European Union containing them. In addition, algae brown can accumulate heavy metals such as arsenic. A 2004 study found that hijiki seaweed grampian electronics contained significant amounts of this substance. Consequently, the British Food Standards Agency (UK Food Standards Agency) advises consumers to avoid consumption of hijiki. 4 Last, often, the sodium content of algae is high, which should take into account the people grampian electronics who have to control grampian electronics the amount of salt in your diet. Fiber Algae are rich in soluble fibers such as alginates, carrageenan and agar barely digested in the intestine and help to increase the feeling of satiety. Alginates and carrageenan from seaweed are also used to improve the texture and stability of some processed foods (such as sausages or the croissants). While extracts of seaweed fiber can have a slimming potential, algae are probably similar to fruit and vegetables effect regarding satiety (and weight control). A portion of 8 g of dried seaweed provides about one-eighth of that amount of fiber needed grampian electronics daily an adult, which is similar to the amount it contributes grampian electronics a banana. Other nutrients algae contain very small amounts of fat and some varieties grampian electronics They are rich in protein. Many contain essential amino acid levels similar to legumes and eggs. They also contain grampian electronics vitamins A, C and E in useful quantities, and are one of the few plant sources of vitamin B 12, which makes them a valuable addition to a vegetarian or vegan diet (v
