Salt and pickles

It causes a lot of unease to be told that what has been accepted for ages as incontrovertible truth is perhaps misguided. Recent health studies have found that vegetable oil-based fats are not only not harmful but are effective in preventing heart diseases. Now, a well-known doctor (Dr.B.M.Hegde) wonders if we have not demonised common salt a little too unintelligently:"Another curse of reductionism in science“The fact that salt is a powerful emetic as well as a potent laxative should convince the most skeptical that it is not meant to form an important part of the human diet.” — John H Tobe (in Salt and Your Health)There is an old adage in this part of the world. “There is no one more loving than a mother and there is no food tastier than salt.” Some of these sayings come from hundreds of years of observation-based holistic research which appears much more reliable than the present-day cross-sectional short-term studies of reductionism and surrogate end-points. Salt has got a bad name. If you have high blood prssure (BP) and heart conditon, eat a salt-free diet. Says who? Says a single study. The one-study basis of salt restriction in the world is a longitudinal study of Lewis Dahl which showed that higher salt intake seems to keep the blood pressure up. Further scrutiny of this study did show major fallacies in his calculations; but, for some unexplained reasons, the official stand has been to observe salt restriction, to stay healthy and be fit.A common diagnosis in elderly people hospitalised these days is hyponatremia which  results in neurological manifestations ending in coma. In my younger days, we did not see it as frequently as we see it nowadays. There are many reasons for this increased incidence. The number of patients on diuretics, for various reasons, is increasing while, at the same time, salt restriction has become more and more aggressive in hospitals. Many other drugs in common day-to-day use also upset the electrolyte balance in the human system. 
All in all, patients pay for their ignorance with their lives. The time has come to take a re-look. What made me do this was a study recently published—of nearly 1,000 patients with heart failure —who were observed for the effect of conventional salt restriction on outcome, through mortality and morbidity. Dr Rami Doukky, a cardiologist and associate professor at Rush University Medical Center in Chicago, leading a team of resarchers, found that patients with moderate heart failure who stuck to a low-sodium diet were 85% more likely to die or require hospitalisation for heart disease, compared to similarly ill patients who didn’t restrict their salt intake.
Since this is only an observational study, a prospective randomised controlled study might be better. However, having said that, I feel that the study has thrown much light on this vexed problem of sodium chloride and human health. 
As I never tire of saying, the universe does not work in bits and pieces. It works as whole. Trying to understand how nature works is called science. 
But in reductionist science, which the Western medicine follows as the basis of human physiology, scientists only get a keyhole view of the goings on inside, missing the essential, always. That is why medicine is not a perfect science; it is only a statistical science treating all patients as identical (‘one size fits all’ hypothesis) which they are NOT. All our efforts at RCTs (randomised controlled trials) have, per force, to be unreliable as two human beings are NOT like two molecules in your laboratory to be compared.
Let me assure you that we will never be able to get a clear cut black & white demarcation here. “Truly man is a marvellously vain, diverse, and undulating object. It is hard to form any constant and uniform judgement on him,” was Michel de Montaigne’s opinion about us humans. Human physiologists have yet to fully understand the enigma of water and electrolyte balance in the human body. 
It is now known that human system can even get any electrolytes it wants from other electrolytes. This is a new concept, known to Russian scientists for decades but kept away from the West. This is called transmutation. All these compound our confused understanding of these electrolytes. Sodium taken in isolation (reductionism) might increase the BP and abet heart failure. God only knows what it does in the whole body with many other players in the field and its capacity to transmutate. 
Any talk about our underlying physiology might not be true because our thinking is stunted, thanks to our reductionist science. Long-term outcomes research is our future guide and the study cited above is a good pointer for us to know that all is not well with the way of treating heart failure. Mortality due to heart failure, with or without treatment, remains almost the same except for the dent (small gain) that diuretics have made in that area. Repeated hospitalisation has also not come down after we introduced so many drugs for heart failure treatment. 
The only drugs which help, for sure, are diuretics. Beta-blockers, ACE (angiotensin converting enzyme) inhibitors, ARBs (angiotensin-II receptor blockers) and all other newer modalities have not had a long enough experience in the field. None of these drugs had any independent studies to recommend its use. Available studies are all company-funded!
We need more unbiased, independently-funded studies to answer these questions. Drug company-funded studies will, of course, give results acceptable to their funders. The above-cited study also showed another important parameter. Salt restriction did not improve treatment outcomes or quality of life but did increase significantly the incidence of low-salt syndrome, especially in the old elderly in the ICUs. 
Drawing sustenance from our ancient wisdom, which will be frowned upon by my ‘scientific minded’ colleagues, gives us another angle to this problem. The best diet to help us in the lean seasons, like long rainy seasons, is our pickles. Studies on pickles have shown that the salt in the pickle does not damage human health; but increases pickle’s shelf-life. Western junk foods, on the contrary, contain so much of pure sodium chloride that it is bad for health. Professor Macgregor’s studies in London on cornflakes showed that cornflakes contain fourfold salt, compared to sea water, and is bad. 
Our ancient rock salt, not the present-day refined salt, contained many other salts, in addition to sodium, like potassium and magnesium chloride, that might be good for health in the long run; the sodium content does not differ in the two, though. 
Our ancient food preservation techniques were also based on salt but not the ‘pure’ and refined salt of today. We have to study their goodness to extrapolate their use modern food-processing methods.
In conclusion, the above-mentioned study needs further clarifications. As of now, our idea of connecting salt to hypertension and heart failure has not been questioned but what we have to establish are two things: 1) Is salt intake detrimental to health in the long run? And 2) Should we restrict salt for the young people in the fond hope of keeping them away from hypertension and heart failure?
Human physiology of water and electrolyte balance needs to be re-looked at to make our interventions in seriously ill patients more rational. For the time being, my take on the subject would be to let nature decide our future benefit as far is salt is concerned. Let us get enough salt from fresh, plant-based foods. Let us avoid adding ‘refined’ table salt to food. Let us also avoid very high salt containing foods like the Western junk preserved foods.

Bangladesh Bank loses money

In a swift (unintended pun) operation, the central bank of Bangladesh, the Bangladesh Bank, has lost $61 million since its SWIFT terminal was reportedly kept logged on after office hours in February. Its system was hacked with ease apparently by some Chinese criminals and instructions were issued to NY Fed where many central banks maintain accounts to transfer about $ 1 billion to various payees. Surprisingly, only $101 million was transferred mainly to Philippines and Sri Lanka. Bankers in Sri Lanka became suspicious about these transfers and sought verification from NY Fed. NY Fed got alerted and further damage was prevented.

$60 Million transferred to Philippines disappeared into a black hole in the form of a casino. It is strange that casinos do not attract KYC norms in that country. So the identity of ultimate recipients will be mysterious for ever. Operational laxity in Bangladesh Bank and NY Fed and criminal complicity in Philippines are astounding. Combination of money and negligence never fails to attract fraudsters.

Brazil shows the way for India

Brazil is reeling under Petrobras corruption scandal. The country knows how to deal with it. A former President, Lula, despite his popularity was taken into custody. His protegee, the present President, tried to help him out by taking him in her ministry and thereby granting him immunity. But the investigating authority would not oblige. It has ruled that Lula cannot join the ministry to subvert law.

Can we expect similar respect for justice and governance in India?

Hedged Reporting

Report 1 : "Mallya on Thursday sought an extension till April but ED officials , who did not want to be quoted, said it's unlikely the agency would give him that long."

Report 2 : "ED likely to give Mallya extension: ED is likely to give Vijay Mallya time till April for making a personal appearance before it."

Both reports have appeared in the front page of The Economic Times, one below the other. So, whatever happens, ET is right.

Happiness Index

"The World Happiness Report is a landmark survey of the state of global happiness. The first report was published in 2012, the second in 2013, and the third in 2015. The World Happiness Report 2016 Update, which ranks 156 countries by their happiness levels, was released today in Rome in advance of UN World Happiness Day, March 20th. Leading experts across fields – economics, psychology, survey analysis, national statistics, health, public policy and more – describe how measurements of well-being can be used effectively to assess the progress of nations. The reports review the state of happiness in the world today and show how the new science of happiness explains personal and national variations in happiness. They reflect a new worldwide demand for more attention to happiness as a criteria for government policy."

In this survey, India ranks 118. A disappointing finding for a nation that claims to be philosophical. The report says,"Since life would be very unpleasant in a country with the world’s lowest incomes, 
lowest life expectancy, lowest generosity, most corruption, least freedom and least social support, it is referred to as “Dystopia,” in contrast to Utopia." Obviously, India lies much nearer to Dystopia than to Utopia. If we leave it to our politicians, the day is not far off when we will be Dystopia itself.

Vijay Mallya (contd.)

Vijay Mallya has tweeted:

"Let media bosses not forget help, favours,accommodation that I have provided over several years which are documented. Now lies to gain TRP ?"

He is cautioning mediapersons, bankers, politicians and perhaps judges too.  A notable example of crony capitalism.

Vijay Mallya

Vijay Mallya need not come back to India. SBI has permitted him to avail future loans at its London branch.
This is real customer service. Why else should the bank have foreign branches if not to facilitate hassle-free transactions?

Action against corruption

In Brazil, the former prime minister, Lula is in police custody on corruption charges. In Malaysia, the present prime minister, Najib Razak, is under investigation for sleaze.

For some strange reasons, the Indian government prefers not to probe the giant-sized corruption of the UPA II government. Not proceeding against corruption is itself a kind of corruption.

Tax on EPF

By a strange coincidence, as per government's arithmetic, revenue earnings from tax on EPF  (Rs.200 crore) equal the proposed expenditure on celebration of 125th birthday of Deen Dayal Upadhyay and 350th birthday of Sri Guru Gobind Singh. If the government is unable to bear the revenue loss of Rs.200 crore, it may drop the birthday bash.
