WHO Sets First Limits for Safe Melamine Levels in Food

[amazon_link asins=’B01M1DJ6RU,B01IBG96ZE,B010YWBSUY,B017ALWTZA,B011DLW1I8,B01MEF9H06′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’5171e71c-f349-11e6-94ef-2dacfdd11aa5′]

GENEVA: The World Health Organization on Friday issued safety limits for melamine levels in food as international concern mounted over a widening tainted food scandal in China.

……………………

It is the first time WHO experts have issued safety limits for the use of the industrial chemical and they stressed that melamine should not be used in food at all.

The so-called Tolerable Daily Intake (TDI) has been fixed at 0.2 mg per kilogramme of body weight. This means that a person who weighs 50kg can tolerate up to 10mg of melamine per day, said the WHO.

“We expect this could better guide the authorities in protecting the health of their public,” said Jorgen Schlundt, WHO director for food safety.

The UN agency stressed however that the industrial chemical “should not be in food” even though traces are sometimes unavoidable.

“The TDI is meant to help national authorities set safe limits in food for withdrawal purposes should melamine be detected as a result of intentional adulteration,” added the WHO.

China said Monday that 294,000 children had been made ill by consuming dairy products containing melamine, with 154 still in serious condition.

Melamine can cause kidney stones if taken in excessive levels.

It has been routinely mixed into Chinese milk and dairy products to give them the impression of having higher protein content.

China said six deaths since September may have been caused by tainted dairy products. The confirmed death toll so far is three infants.

The scandal has led many countries around the world, including the 27-nation European Union, to ban Chinese milk imports.

This week, the EU added imports of Chinese food containing soya to the ban list. Shipments of Chinese-made baking powder will also have to be tested after high levels of melamine were found.

Botanical Name: Illicium verum
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Austrobaileyales
Family: Illiciaceae/Magnoliaceae
Genus: Illicium
syn: I. anisatum
Other Names:-Anise Stars, Badain, Badiana, Chinese Anise
French: anis de la Chine, anise étoilé, badiane
German: Sternanis

Habitat: Native to China and Vietnam, star anise is today grown almost exclusively in southern China, Indo-China, and Japan. It was first introduced into Europe in the seventeenth century.

Plant Description and Cultivation:
A small to medium evergreen tree of the magnolia family, reaching up to 8m (26ft). The leaves are lanceolate and the axillary flowers are yellow. The tree is propagated by seed and mainly cultivated in China and Japan for export and home markets. the fruits are harvested before they ripen, then sun dried.

Spice Description:
Star anise is the unusual fruit of a small oriental tree. It is, as the name suggests, star shaped, radiating between five and ten pointed boat-shaped sections, about eight on average. These hard sections are seed pods. Tough skinned and rust coloured, they measure up to 3cm (1-1/4”) long. The fruit is picked before it can ripen, and dried. The stars are available whole, or ground to a red-brown powder....CLICK & SEE
Bouquet: Powerful and liquorice-like, more pungent and stronger than anise.
Flavour: Evocative of a bitter aniseed, of which flavour star anise is a harsher version. Nervertheless, the use of star anise ensures an authentic touch in the preparation of certain Chinese dishes.

Star anise is a spice that closely resembles anise in flavor, obtained from the star-shaped pericarp of Illicium verum, a small native evergreen tree of southwest China. The star shaped fruits are harvested just before ripening. It is widely used in Chinese cuisine, in Indian cuisine where it is a major component of garam masala, and in Malay/Indonesian cuisine. It is widely grown for commercial use in China, India, and most other countries in Asia. Star anise is an ingredient of the traditional five-spice powder of Chinese cooking. It is also one of the ingredients used to make the broth for the Vietnamese noodle soup called ph?. It is used as a spice in preparation of Biryani in Andhra Pradesh, a south Indian State.

Medicinal Properties:
Like anise, star anise has carminative, stomachic, stimulant and diuretic properties. In the East it is used to combat colic and rheumatism. It is a common flavouring for medicinal teas, cough mixtures and pastilles.

Medicinal uses:
Star anise has been used in a tea as a remedy for colic and rheumatism, and the seeds are sometimes chewed after meals to aid digestion.

Shikimic acid, a primary feedstock used to create the anti-flu drug Tamiflu, is produced by most autotrophic organisms, but star anise is the industrial source. In 2005, there was a temporary shortage of star anise due to its use in making Tamiflu. Late in that year, a way was found of making shikimic acid artificially. A drug company named Roche now derives some of the raw material it needs from fermenting E. coli bacteria. There is no longer any shortage of star anise and it is readily available and is relatively cheap.

Star anise is grown in four provinces in China and harvested between March and May. The shikimic acid is extracted from the seeds in a ten-stage manufacturing process which takes a year. Reports say 90% of the harvest is already used by the Swiss pharmaceutical manufacturer Roche in making Tamiflu, but other reports say there is an abundance of the spice in the main regions – Fujian, Guangdong, Guangxi and Yunnan.

Japanese star anise (Illicium anisatum), a similar tree, is not edible because it is highly toxic; instead, it has been burned as incense in Japan. Cases of illness, including “serious neurological effects, such as seizures”, reported after using star anise tea may be a result of using this species. Japanese star anise contains anisatin, which causes severe inflammation of the kidneys, urinary tract and digestive organs.

Culinary Uses:
Star anise is used in the East as aniseed is in the West. Apart from its use in sweetmeats and confectionery, where sweeteners must be added, it contributes to meat and poultry dishes, combining especially well with pork and duck. In Chinese red cooking, where the ingredients are simmered for a lengthy period in dark soy sauce, star anise is nearly always added to beef and chicken dishes. Chinese stocks and soups very often contain the spice.. It flavours marbled eggs, a decorative Chinese hors d’oeuvre or snack. Mandarins with jaded palates chew the whole dried fruit habitually as a post-prandial digestant and breath sweetener – an oriental comfit. In the West, star anise is added in fruit compotes and jams, and in the manufacture of anise-flavoured liqueurs, the best known being anisette. It is an ingredient of the mixture known as “Chinese Five Spices”.

Star anise contains anethole, the same ingredient which gives the unrelated anise its flavor. Recently, star anise has come into use in the West as a less expensive substitute for anise in baking as well as in liquor production, most distinctively in the production of the liquor Galliano. It is also used in the production of Sambuca, pastis, and many types of absinthe.

Beware! Chinese food unhealthy

: The average Chinese restaurant’s menu in the United States is a sea of nutritional taboos, a consumer group said.

click & see

A plate of General Tso’s chicken, for example, is loaded with about 40% more sodium, and more than half the calories, needed for an entire day.

The battered fried chicken dish with vegetables has 1,300 calories, 3,200 milligrams of sodium and 11 grams of saturated fat.

That is before the rice’s 200 calories a cup. And after the eggrolls’ 200 calories and 400 milligrams of sodium.

“I don’t want to put all the blame on Chinese food,”said Bonnie Liebman, nutrition director of the Center for Science in the Public Interest, which did a report released on Tuesday.

“Across the board, American restaurants need to cut back on calories and salt, and in the meantime, people should think of each meal as not one, but two, and bring home half for tomorrow,”Liebman said.

The average person needs around 2,000 calories a day and 2,300 milligrams of salt, about one teaspoon of salt, according to government guidelines.

In some ways, Liebman said, Italian and Mexican restaurants are worse for your health, because their food is higher in saturated fat, which can increase the risk of heart disease.

While Chinese restaurant food is bad for the waistline and blood pressure — sodium contributes to hypertension — it offers vegetable-rich dishes and the kind of fat that is not bad for your heart.

However — this is a big however — the veggies are not off the hook. A plate of stir-fried greens has 900 calories and 2,200 milligrams of sodium. And eggplant in Garlic Sauce has 1,000 calories and 2,000 milligrams of sodium. “We were shocked. We assumed the vegetables were all low in calories,”Liebman said.

Botanical Name :Momordica charantia
Family: Cucurbitaceae
Genus: Momordica
Species: M. charantia
Kingdom: Plantae
Order: Cucurbitales

Common Names:Bitter melon, bitter gourd, bitter squash or balsam-pear  in English, has many other local names. Goya  from Okinawan and karela from Sanskrit are also used by English-language speakers.

Habitat :  Momordica charantia is a tropical and subtropical vine of the family Cucurbitaceae, widely grown for edible fruit, which is among the most bitter of all vegetables. English names for the plant and its fruit include bitter melon or bitter gourd (translated from Chinese: ??; pinyin: kugua). The original home of the species is not known, other than that it is a native of the tropics. It is widely grown in India, South Asia, The Philippines, Southeast Asia, China, Africa and the Caribbean.

Also known as Ku gua, the herbaceous, tendril-bearing vine grows to 5 m. It bears simple, alternate leaves 4-12 cm across, with 3-7 deeply separated lobes. Each plant bears separate yellow male and female flowers.

Description: This herbaceous, tendril-bearing vine grows to 5 m. It bears simple, alternate leaves 4–12 cm across, with three to seven deeply separated lobes. Each plant bears separate yellow male and female flowers. In the Northern Hemisphere, flowering occurs during June to July and fruiting during September to November…..CLICK & SEE

The fruit has a distinct warty exterior and an oblong shape. It is hollow in cross-section, with a relatively thin layer of flesh surrounding a central seed cavity filled with large, flat seeds and pith. The fruit is most often eaten green, or as it is beginning to turn yellow. At this stage, the fruit’s flesh is crunchy and watery in texture, similar to cucumber, chayote or green bell pepper, but bitter. The skin is tender and edible. Seeds and pith appear white in unripe fruits; they are not intensely bitter and can be removed before cooking.

As the fruit ripens, the flesh (rind) becomes somewhat tougher and more bitter, and many consider it too distasteful to eat. On the other hand, the pith becomes sweet and intensely red; it can be eaten uncooked in this state, and is a popular ingredient in some Southeast Asian salads.

When the fruit is fully ripe, it turns orange and mushy, and splits into segments which curl back dramatically to expose seeds covered in bright red pulp.

Varieties:
Bitter melon comes in a variety of shapes and sizes. The cultivar common to China is 20–30 cm long, oblong with bluntly tapering ends and pale green in color, with a gently undulating, warty surface. The bitter melon more typical of India has a narrower shape with pointed ends, and a surface covered with jagged, triangular “teeth” and ridges. It is green to white in color. Between these two extremes are any number of intermediate forms. Some bear miniature fruit of only 6–10 cm in length, which may be served individually as stuffed vegetables. These miniature fruit are popular in Bangladesh, India (common name ‘Karela’), Pakistan, Nepal and other countries in South Asia. The sub-continent variety is most popular in Bangladesh and India.

Bitter melon is commonly used as a vegetable in tropical areas such as East Africa, Asia, the Caribbean, and South America. The plant gets its name from the bitter taste of its fruit and juice; however, cooking it with the appropriate spices can reduce the bitterness. In addition to being a food source, bitter melon is employed as an herbal remedy in many parts of the world. While the seeds, leaves and vines of bitter melon may all be used, the fruit is used most often for medicinal purposes.

At lease three types of compounds in bitter melon are believed to lower blood sugar, which can benefit people with diabetes mellitus. It is still unclear whether these compounds work together or individually, but several controlled clinical studies have confirmed that bitter melon is beneficial in controlling the symptoms of diabetes.

Test-tube studies have also shown that two proteins found in bitter melon — alpha-momorcharin and beta-momorcharin — inhibit the AIDS virus. However, these studies have not been conducted in humans.

Culinary uses:
Bitter melons are seldom mixed with other vegetables due to the strong bitter taste, although this can be moderated to some extent by salting and then washing the cut melon before use.

Bitter melon is often used in Chinese cooking for its bitter flavor, typically in stir-fries (often with pork and douchi), soups, and also as tea.

It is also a popular vegetable in Indian and Pakistani cooking, where it is often prepared with potatoes and served with yogurt on the side to offset the bitterness. Bitter melon fried in oil and then stuffed with other spicy ingredients is very popular in Andhra Pradesh, a south Indian state.

Bitter melon is rarely used in mainland Japan, but is a significant component of Okinawan cuisine.

In Vietnam, raw bitter melon slices consumed with dried meat floss and bitter melon soup with shrimp are popular dishes.

It is prepared into various dishes in the Philippines, where it is known as ampalaya. Ampalaya may also be stir-fried with ground beef and oyster sauce, or with eggs and diced tomato. A very popular dish from the Ilocos region of the Philippines, pinakbet, consists mainly of bitter melons, eggplant, okra, string beans, tomatoes, lima beans, and other various regional vegetables stewed with a little bagoong-based stock.

The young shoots and leaves may also be eaten as greens; in the Philippines, where bitter melon leaves are most commonly consumed, they are called dahon (leaves) ng ampalaya. The seeds can also be eaten, and give off a sweet taste, but have been known to cause vomiting and stomach upset.

Medicinal uses:
Bitter melons have been used in various Asian traditional medicine systems for a long time . Like most bitter-tasting foods, bitter melon stimulates digestion. While this can be helpful in people with sluggish digestion, dyspepsia, and constipation, it can sometimes make heartburn and ulcers worse. The fact that bitter melon is also a demulcent and at least mild inflammation modulator, however, means that it rarely does have these negative effects, based on clinical experience and traditional reports.

Perhaps the best substantiated use to date is that of bitter melon for people with diabetes mellitus. Several preliminary (non-randomized, non-blinded) clinical trials suggest this benefit, though controlled trials are necessary for confirmation . In the Philippines, bitter melon tea is used in blood sugar control for poor people as exemplified in the very successful Operation Diabetes . For a detailed review of studies involving bitter melon and diabetes, see Abascal and Yarnell 2005.

In ayurvedic medicine, bitter melon is popularly seen as a “plant-insulin.” It has been demonstrated that bitter melon contains a protein similar to bovine insulin, sometimes referred to as p-insulin or polypeptide-p (Baldwa, et al. 1977). When purified and injected subcutaneously into patients with insulin-dependent diabetes mellitus (IDDM), it acted very similar to slow-acting animal insulins and was able to sustain patients . One child in this small study who previously had many side effects from bovine insulin was able to use p-insulin exclusively for 5 months with no sign of problems. This represents the potential for a vegetarian alternative to animal insulin for patients with IDDM, as well as a potentially more sustainable source of insulin, and should be further developed. It is not possible to substitute eating bitter melon for taking insulin.

Though it has been claimed that bitter melon’s bitterness comes from quinine, no evidence could be located supporting this claim. Bitter melon is traditionally regarded by Asians, as well as Panamanians and Colombians, as useful for preventing and treating malaria. Laboratory studies have confirmed that various species of bitter melon have anti-malarial activity, though human studies have not yet been published .

Laboratory tests suggest that compounds in bitter melon might be effective for treating HIV infection . As most compounds isolated from bitter melon that impact HIV have either been proteins or glycosproteins (lectins), neither of which are well-absorbed, it is unlikely that oral intake of bitter melon will slow HIV in infected people. It is possible oral ingestion of bitter melon could offest negative effects of anti-HIV drugs, if a test tube study can be shown to be true in people . In one preliminary clinical trial, an enema form of a bitter melon extract showed some benefits in people infected with HIV (Zhang 1992). Clearly more research is necessary before this could be recommended.

The other realm showing the most promise related to bitter melon is as an immunomodulator. One clinical trial found very limited evidence that bitter melon might improve immune cell function in people with cancer, but this needs to be verified and amplified in other research . If proven correct this is another way bitter melon could help people infected with HIV


How much bitter melon should I take?

For those who can withstand the bitter taste, many herbalists recommend eating one small melon; 100 millileters of a bitter melon decoction; or two ounces of fresh bitter melon juice per day. For people who cannot stand the taste, some practitioners recommend bitter melon tinctures (five millileters, two or three times per day).

What forms of bitter melon are available?

Fresh bitter melon and bitter melon juice can be found at many specialty stores and Asian markets. Bitter melon extracts and tinctures can be found at some health food stores.

What can happen if I take too much bitter melon? Are there any interactions I should be aware of? What precautions should I take?

Excessive amounts of bitter melon juice may cause abdominal pain and diarrhea. In addition, patients with hypoglycemia should avoid bitter melon, because it could theoretically worsen their condition.

At present, there are no well-known drug interactions with better melon. However, make sure to consult with a health care provider before taking bitter melon (or any other dietary supplement).
