Hijiki (ヒジキ, 鹿尾菜 or 羊栖菜, hijiki) (Sargassum fusiforme, syn. Hizikia fusiformis), sometimes called hiziki, is a brown sea vegetable that grows wild on the rocky coastlines of East Asia.
Hijiki has been a part of the Japanese culinary sphere and diet for centuries. It is rich in dietary fiber and essential minerals such as calcium, iron, and magnesium. According to Japanese folklore, hijiki aids health and beauty, and thick, black, lustrous hair is connected to regular consumption of small amounts.[ citation needed ] Hijiki has been sold in United Kingdom natural products stores for 30 years and its culinary uses have been adopted in North America.
Recent studies have shown that hijiki contains potentially toxic quantities of inorganic arsenic, and the food safety agencies of several countries (excluding Japan), including Canada, the United Kingdom, and the United States, have advised against its consumption. [1] [2] [3]
In 1867 the word "hijiki" first appeared in an English-language publication: A Japanese and English Dictionary by James C. Hepburn.
Starting in the 1960s, the word "hijiki" started to be used widely in the United States,[ citation needed ] and the product (imported in dried form from Japan) became widely available at natural food stores and Asian-American grocery stores, due to the influence of the macrobiotic movement, and in the 1970s with the growing number of Japanese restaurants.[ citation needed ]
Hijiki is green to brown in colour when found in the wild. Fishermen and professional divers harvest the hijiki with a sickle at low tide during the spring tide from May to March. After collection, the seaweed is boiled and dried before being sold as dried hijiki. Once processed, dried hijiki turns black. To prepare dried hijiki for cooking, it is first soaked in water then cooked with ingredients like soy sauce and sugar to make a dish that goes by the same name.
In Japan, hijiki is normally eaten with other foods such as vegetables or fish. It may be added to foods that have been steamed, boiled, marinated in soy sauce or fish sauce, cooked in oil, or added to soup, stir fries or quiches. Hijiki may be mixed with rice, but not used as a wrap, to prepare sushi. Konjac is typically prepared with hijiki mixed in to give the dish known by the same name its characteristic grey color and texture.
In Korea, the seaweed is called tot (톳) and eaten as namul (seasoned vegetable side dish) or cooked with bap (rice).
Hijiki contains dietary fiber and minerals such as iron, calcium, and magnesium. Dietary fiber is good for the intestine and iron helps to prevent anemia. The ratio of calcium to magnesium in hijiki is 2 to 1.
Several government food safety agencies advise consumers to avoid consumption of hijiki seaweed. Testing showed that it contains significantly higher concentrations of inorganic arsenic than other types of seaweed, and these results have been independently verified. [4] Government food safety agencies that advise against consumption include the Canadian Food Inspection Agency (CFIA), [5] the Food Standards Agency (FSA) of the United Kingdom, [6] and the United States Department of Agriculture (USDA). [7]
The Ministry of Health, Labour and Welfare of Japan responded with a report pointing out that while the consumption of more than 4.7 g hijiki seaweed per day could result in an intake of inorganic arsenic that exceeds the tolerable daily intake for this substance, the average daily consumption for Japanese people is estimated at 0.9 g. [8] Several of the reports[ which? ] from other food safety agencies acknowledged that occasional hijiki consumption was unlikely to cause significant health risks but advised against all consumption regardless. [6]
Although no known illnesses have been associated with consuming hijiki seaweed to date, inorganic arsenic has been identified as carcinogenic to humans. Exposure to inorganic arsenic has been linked with gastrointestinal effects, anemia, and liver damage. [9] People who follow a macrobiotic diet that often includes large amounts of seaweed may be at greater risk.[ citation needed ]
A macrobiotic diet is a fad diet based on ideas about types of food drawn from Zen Buddhism. The diet tries to balance the supposed yin and yang elements of food and cookware. Major principles of macrobiotic diets are to reduce animal products, eat locally grown foods that are in season, and consume meals in moderation.
Nori(海苔) is a dried edible seaweed used in Japanese cuisine, usually made from species of the red algae genus Pyropia, including P. yezoensis and P. tenera. It has a strong and distinctive flavor, and is generally made into flat sheets and used to wrap rolls of sushi or onigiri.
Spaghetti is a long, thin, solid, cylindrical pasta. It is a staple food of traditional Italian cuisine. Like other pasta, spaghetti is made of milled wheat, water, and sometimes enriched with vitamins and minerals. Italian spaghetti is typically made from durum-wheat semolina. Usually the pasta is white because refined flour is used, but whole wheat flour may be added. Spaghettoni is a thicker form of spaghetti, while spaghettini is a thinner form. Capellini is a very thin spaghetti, sometimes known colloquially as "angel hair pasta", while Vermicelli refers to intermediate widths, varying between the United States and Italy.
In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, most are not. Minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids. The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. The remaining elements are called "trace elements". The generally accepted trace elements are iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine, and selenium; there is some evidence that there may be more.
Seitan is a food made from gluten, the main protein of wheat. It is also known as miànjīn, fu, milgogi, wheat meat, gluten meat, or simply gluten. It is made from vital wheat gluten, a flour-like substance primarily consisting of gluten extracted from wheat flour.
Bran, also known as miller's bran, is the hard layers of cereal grain surrounding the endosperm. It consists of the combined aleurone and pericarp. Corn (maize) bran also includes the pedicel. Along with the germ, it is an integral part of whole grains, and is often produced as a byproduct of milling in the production of refined grains.
Wakame(Undaria pinnatifida) is a species of kelp native to cold, temperate coasts of the northwest Pacific Ocean. As an edible seaweed, it has a subtly sweet, but distinctive and strong flavour and satiny texture. It is most often served in soups and salads.
Sargassum is a genus of brown macroalgae (seaweed) in the order Fucales of the Phaeophyceae class. Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species. Most species within the class Phaeophyceae are predominantly cold-water organisms that benefit from nutrients upwelling, but the genus Sargassum appears to be an exception. Any number of the normally benthic species may take on a planktonic, often pelagic existence after being removed from reefs during rough weather. Two species have become holopelagic—reproducing vegetatively and never attaching to the seafloor during their lifecycles. The Atlantic Ocean's Sargasso Sea was named after the algae, as it hosts a large amount of Sargassum.
Kinpira (金平) is a Japanese cooking style that can be summarized as a technique of sauté and simmer. The most common dish made with this technique is Kinpira Gobo, braised burdock root. Kinpira is commonly used to cook root vegetables such as carrots, burdock root, and lotus root; skins of squash such as Kabocha; vegetables such as mushrooms or broccoli; seaweeds such as arame and hijiki; other foods including tofu, capsicums, and wheat gluten (namafu); and meat such as chicken thigh, pork, and beef. The base sauce is made up of soy sauce, mirin, sugar, and chili peppers.
Noodles are a staple of Japanese cuisine. They are often served chilled with dipping sauces, or in soups or hot dishes. Noodles were introduced to Japan from China during the Song Dynasty between the Heian until the early Kamakura period.
Pancit, also spelled pansít, is a general term referring to various traditional noodle dishes in Filipino cuisine. There are numerous types of pancit, often named based on the noodles used, method of cooking, place of origin, equal and constant diameter or the ingredients. Most pancit dishes are characteristically served with calamansi, which adds a citrusy flavor profile.
Arctium lappa, commonly called greater burdock, gobō (牛蒡/ゴボウ), edible burdock, lappa, beggar's buttons, thorny burr, or happy major is a Eurasian species of plants in the family Asteraceae, cultivated in gardens for its root used as a vegetable. It has become an invasive weed of high-nitrogen soils in North America, Australia, and other regions.
Chicken is the most common type of poultry in the world. Owing to the relative ease and low cost of raising chickens—in comparison to mammals such as cattle or hogs—chicken meat and chicken eggs have become prevalent in numerous cuisines.
Okinawan cuisine is the cuisine of the Okinawa Prefecture of Japan. The cuisine is also known as Ryūkyūan cuisine, a reference to the Ryukyu Kingdom. Due to differences in culture, historical contact between other regions, climate, vegetables and other ingredients, Okinawan cuisine differs from mainland Japanese cuisine.
Glutamate flavoring is the generic name for flavor-enhancing compounds based on glutamic acid and its salts (glutamates). These compounds provide an umami (savory) taste to food.
Tofu is a food prepared by coagulating soy milk and then pressing the resulting curds into solid white blocks of varying softness: silken, soft, firm, extra firm. Tofu is also known as bean curd in English. It is a traditional component of East Asian and Southeast Asian cuisines that has also been consumed in China for over 2,000 years. In modern Western cooking, it is most often treated as a meat substitute.
Edible seaweed, or sea vegetables, are seaweeds that can be eaten and used for culinary purposes. They typically contain high amounts of fiber. They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. Seaweeds are also harvested or cultivated for the extraction of polysaccharides such as alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids.
Steam minced pork refers to a savory dish popular in Hong Kong and the Guangdong area of China. Consisting mainly of minced pork, it typically includes ingredients such as dried squid (土魷) and preserved cabbage (梅菜). The dish is cooked by steaming over a pot of boiling water until it is well cooked. The seasonings usually include soy sauce, salt, sugar and corn flour and occasionally white pepper and sesame oil. It is usually served with rice during lunch or dinner.
Gegeolmu, or gegeol radish, is a variety of white radish. It is a round, pungent radish with a thick rind and firm flesh that does not get soft even after a few years of storage as kimchi.
