ARSENIC MENACE

Image
By
Around 10 million people in India are unknowingly consuming high levels of arsenic in their water, with many showing signs of chronic poisoning. A recent investigation showed that the ground water (wells, deep tube wells) of several parts of eastern Uttar Pradesh and Bihar contain far higher levels of arsenic than is considered safe and permissible for human consumption.
The plight of people residing in these regions came to light due to the dark spots and patches on their skins and by their rough and scaly palms and soles. People from adjacent regions could smell there was something wrong with inhabitants of some villages and declined marrying into these homes out of fear of some infection.
While the disease is not infectious, arsenosis, as it is called in medical science, is a disease that is being increasingly recognized across the world. Geographical regions with high arsenic content in ground water and human inhabitants of the regions showing a characteristic disease pattern have been reported from 30 countries.
The first reports from India came from West Bengal and adjacent parts of Bangladesh n 1986 by Prof DN Guha Mazumdar, an eminent scientist from Kolkata who drew the attention of the World Health Organization to the blight. People residing in high arsenic zones showed, apart from the characteristic skin changes, involvement of the lungs, eyes, nerves, liver and blood vessels, and suffered from anemia. Mothers from these regions had a 6-fold higher rate of still births. Further cancers occured more frquently here, especially of the throat and bladder.
Normal drinking water contains around 50 -100 ug of arsenic per litre. Levels above 200 are considered unsafe for the human body. The ground water of several villages has been found to have ten times these levels, sometimes crossing 2000 ug/L. Consumption of high levels of arsenic causes excess accummulation of this metal in different organs of the body leading to their slow damage.
Many of the affected people often drop out of work due to weakness, anemia and degeneration of nerves. Swelling of the feet and ankles is common. Involvement of the lungs causes chronic cough and breathlessness adding to their frailty.
 It is not uncommon to see people in their forties and fifties with skin patches and rough palms, languising at home, often labelled as lazy or depressed, unable to cope with strenuous work and earn their livelihhod. Their children often grow up to suffer the same fate as do their offsprings.
As long as their water is not detoxified of arsenic, the dwellers are doomed for generations, except when some children migrate to cities and inadvertently escape the scourge. Boiling water does not help in this case as there are no germs to kill by heating.
And the inhabitants can do very little by their own to save themselves and their families. Only a vigilant and caring governemnt can help with testing, identifying and detoxifying the water in these doomed regions.

How do you like your Tea?

By
The way we drink our tea may not only reflect our taste and style, but our health as well. Tea drinking is around 4700 years old and had its origin in China. Leaves of the shrub Camellia sinensis (tea plant) were in use at that time as a remedy for wounds and diseases. With the legendary emperor Shenong brewing and drinking its extracts, tea drinking became a popular habit in this part of the world. The British, impressed with the brew and the customs that go with drinking it in China and Japan, tried to emulate and evolve a tea-drinking custom of their own, and soon “tea-time”became a familiar term across the globe. Every home or cafe seems to have its own flavour. The north Indian variety of “chay” is a glass of hot creamy milk (more cream as it gets more “special”) with lots of sugar and a lacing of  “tea liquor” of strong tea that grows on lower heights (Assam, Nilgiri, Sri Lanka etc). In contrast, the Chinese and Japanese prefer light green or jasmine tea without a drop of mi...

Food Fads in Liver Disorders

By
In an attempt at trying to do well to those they love, spouses and parents often enforce diets on patients of liver diseases that often turn out to be detrimental. The commonest food fad is pale insipid boiled cabbage being doled out to nauseous patients suffering from hepatitis that makes them puke even more.  The liver, in a way, is a buzzing manufacturing unit that requires lots of energy to keep its multiple functions going. And it derives all this from the food we eat. During disease, such as during an attack of jaundice, when many of the liver cells get killed, the liver attemptsdamage control by trying to regenerate quickly. For its cells to multiply however, it requires a generous supply of energy that comes from carbohydrates, and protein, the building block for its cells and tissues. Boiled green vegetables unfortunately have neither of these. Hence the situation often progresses to that of a starved liver unable to recuperate due to cut-off food suppl...

Colas have No Class

By
Cola drinks, once a symbol of American upmarket style, is now to be found perched mainly on the shelves of road-side ‘paan walas’ and local grocers. True, there still are Americans who drink more colas than water, and consume an average of 2 bottles per day of the tangy fizzy dark drink, but it has clearly fallen in stature as offering it to visitors or serving it at parties is no longer elegant. Premiere schools in Lucknow such as La Martiniere College for girls have shunned colas from their canteen for the last 4 years. The story started with extensive campaigns by HOPE Initiative (Health Oriented Programs and Education) in 2005 creating awareness among the bright students about the long term harms of cola drinks. A heated debate followed in which the rights of an individual student  was pitched against the hazards of allowing gullible youngsters to be enticed by aggressive marketing to gulp colas and fall sick. The intelligent and alert La Marts students dcided on ...
