Cook rice in a way that dramatically cuts the calories

Roberto A Ferdman in The Independent

Rice, the lifeblood of so many nations' cuisines, is perhaps the most ubiquitous food in the world. In Asia, where an estimated 90 percent of all rice is consumed, the pillowy grains are part of almost every meal. In the Caribbean, where the starch is often mixed with beans, it's a staple too. Even here in the United States, where people eat a comparatively modest amount of rice, plenty is still consumed.

Rice is popular because it's malleable—it pairs well with a lot of different kinds of food—and it's relatively cheap. But like other starch-heavy foods, it has one central flaw: it isn't that good for you. White rice consumption, in particular, has been linked to a higher risk of diabetes. A cup of the cooked grain carries with it roughly 200 calories, most of which comes in the form of starch, which turns into sugar, and often thereafter body fat.

But what if there were a simple way to tweak rice ever so slightly to make it much healthier?

An undergraduate student at the College of Chemical Sciences in Sri Lanka and his mentor have been tinkering with a new way to cook rice that can reduce its calories by as much as 50 percent and even offer a few other added health benefits. The ingenious method, which at its core is just a simple manipulation of chemistry, involves only a couple easy steps in practice.

"What we did is cook the rice as you normally do, but when the water is boiling, before adding the raw rice, we added coconut oil—about 3 percent of the weight of the rice you're going to cook," said Sudhair James, who presented his preliminary research at National Meeting & Exposition of the American Chemical Society (ACS) on Monday. "After it was ready, we let it cool in the refrigerator for about 12 hours. That's it."

How does it work?

To understand what's going on, you need to understand a bit of food chemistry.

Not all starches, as it happens, are created equal. Some, known as digestible starches, take only a little time to digest, are quickly turned into glucose, and then later glycogen. Excess glycogen ends up adding to the size of our guts if we don't expend enough energy to burn it off. Other starches, meanwhile, called resistant starches, take a long time for the body to process, aren't converted into glucose or glycogen because we lack the ability to digest them, and add up to fewer calories.

A growing body of research, however, has shown that it might be possible to change the types of starches found in foods by modifying how they are prepared. At the very least, we know that there are observable changes when certain foods are cooked different ways.

Potatoes, for instance, go from having the right kind of starch to the less healthful kind when they are cooked or mashed (sigh, I know). The process of heating and cooling certain vegetables, like peas and sweet potatoes, can also alter the amount of resistant (see: good) starches, according to a 2009 study. And rice, depending on the method of preparation, undergoes observable chemical changes. Most notably, fried rice and pilaf style rice have a greater proportion of resistant starch than the most commonly eaten type, steamed rice, as strange as that might seem.

"If you can reduce the digestible starch in something like steamed rice, you can reduce the calories," said Dr. Pushparajah Thavarajah, a professor who is supervising the research. "The impact could be huge."

Understanding this, James and Thavarajva tested eight different recipes on 38 different kinds of rice found in Sri Lanka. What they found is that by adding a lipid (coconut oil in this case, because it's widely used in Sri Lanka) ahead of cooking the rice, and then cooling the rice immediately after it was done, they were able to drastically change its composition—and for the better.

"The oil interacts with the starch in rice and changes its architecture," said James. "Chilling the rice then helps foster the conversion of starches. The result is a healthier serving, even when you heat it back up."

So far they have only measured the chemical outcome of the most effective cooking method for the least healthful of the 38 varieties. But that variety still produced a 10 to 12 percent reduction in calories. "With the better kind, we expect to reduce the calories by as much as 50 to 60 percent," said James.

Cooking that can change the world

The prospect of lower calorie rice is a big deal. Obesity rates are rising around the world, particularly in the developing world, where people rely more heavily on cheaper food staples. China and India, which are already seeing rising obesity problems, are huge consumers of rice. Rice, of course, is not the sole cause of weight gain. But reducing the amount of calories in a cup of rice by even as little as 10 percent could have an enormous impact for future generations.

"Obesity has been a problem in the United States for some time," said Thavarajah. "But it's becoming a problem in Asia, too. People are eating larger and larger portions of rice, which isn't good."

The researchers still have to test the remaining varieties of rice, including Suduru Samba, which they believe will produce the largest calorie reduction. They also plan to experiment with oils other than coconut oil, like sunflower oil.

A world where commercially sold rice comes pre-cooked and with much fewer calories might not be that far off. People should already be able to replicate the process at home, although James warns the results might vary depending on the type of rice used. And there's good reason to believe the chemistry could be applied to many other popular but less-than-healthy foods.

"It's about more than rice," said Thavarajah. "I mean, can we do the same thing for bread? That's the real question here."

Inequality gets even more entrenched when a person of colour reaches the top

Yasmin Alibhai Brown in The Independent

Black anger is being directed against Barack Obama. Not before time. Millions of African-Americans came out to mark the historical moment of his election in 2008. They praised the Lord, and wept with disbelief and joy. The whole of Africa burst into song. His inauguration was among the most watched global events ever.
In his victory speeches, Obama invoked Abraham Lincoln’s Gettysburg address, and Martin Luther King. Real freedom  would come, he said – so too justice and unity. Today his black supporters can claim, with some justification, that he failed to deliver. Badly. Deplorably.
African-Americans are still more likely to go to prison than to university, to be victimised by police, courts and various state institutions, to be poor and ignored by Washington, to have neo-natal mortality rates twice as high as white babies, to have lower life expectancy, and so on and on.
They are out on the streets again, with brothers and sisters of other races, all across the US – in Washington, New York, Baltimore, Denver, Arizona, everywhere, now shedding tears of rage. ’Tis come to this? How and why? Because five unarmed black males have been killed this year by white police officers.
In July, Eric Garner – father of six, suspected of selling black market cigarettes – was pushed to the ground by a NYPD policeman, and held so tight that he died. A video of the incident records him saying; “I can’t breathe”. In August, Michael Brown perished after he was shot a dozen times by a Darren Wilson  in Ferguson, Missouri. Apparently the teenager had refused orders to walk on the pavement and that led to an altercation. Grand juries decided not to indict the policemen involved.
In November, in Cleveland, Ohio, Tamir Rice was killed by 26-year-old Timothy Loehmann, an officer deemed unfit for duty in 2012. Rice, a schoolboy who loved basketball, had a toy gun in his hands. His family are suing the police. The same month Akai Gurley, 28, was brought down in a darkened stairwell, by police who claim it was an “accidental discharge”. A grand jury will examine this incident.
And finally,  last Tuesday, Rumain Brisbon, who had four children,  was killed by officers in Phoenix, Arizona. Police said they thought the bottle of pills he was holding was a gun. Stevie Wonder wonders how this is possible. I wonder that he wonders.  Living on the hills of fame and fortune, it must be hard to know what is being done to your people way down below.
Seems it is even harder for the President. In February 2012, when Trayvon Martin, 17, was shot dead by a neighbourhood watch co-ordinator in Florida, Obama did at least identify with the pain of the parents and community: “If I had a son, he would look like Trayvon”. (The police officer was, needless to say, acquitted. ) Today Obama makes, makes tepid, middle-management noises about the responsibilities of law enforcers. No fire or fury in his belly any more. Like Colin Powell and Condoleezza Rice, he is now a caretaker of white power.
Obama’s self-belief must be crashing as the accusations build up. Black congressman Charlie Rangel  is  forthright: “Having a black president has not solved the problem at all. ...the colour of one’s skin determines how lives are going to be and whether they live at all.” New York University academic Frank Roberts goes further: “We had hoped he would be Moses; he turned out to be the pharaoh. We have a lame duck president who does not have a moral conscience.” Or as an angry young black man put it: “Obama is a bummer”.
Perhaps it was foolish to expect too much from him.  He has pushed through health care reforms, but that’s it folks. Remember all that loose talk about post-racial America? It actually stopped the fight, disabled the struggle so lethally that today R&B star Alicia Keys is able to say, “We absolutely feel disregarded as human beings.”
It seems inequality gets even more firmly entrenched when a woman or person of colour gets to the very top. Margaret Thatcher didn’t do it for feminism and Theresa May won’t either. We have more MPs and peers of colour than ever before and racism is rising again. Once they get to where they want to, even those who used anti-racism to push in, go strangely quiet, seek approval rather than confrontations.
Obama’s presidency represents the perils of entryism. The rough Texan Lyndon Johnson, who pushed through civil rights legislation, did more for African-Americans than Barack Obama. Johnson didn’t give a damn for the establishment, wasn’t intimidated by white opinion. Here, Ken Livingstone pushed equality policies with courage of a kind we do not see in most black and Asian people in power. My heart cracks as I write this. The truth hurts, but can no longer be dodged or excused.

Bethlehem as you’ve never seen it before

Mary, heavily pregnant, and Joseph arrive in Bethlehem. Christ is born in a stable. The angel Gabriel had foretold this birth of the son of God, come down to save humans from temptations and themselves. The first believers followed the brightest of stars to pay homage. Bethlehem is where it all began.
It’s Christmas again. Millions of Nativity scenes are being re-enacted in infant and primary schools all over the world. Parents film these scenes, and rejoice. But do any of them know what is happening to the actual Bethlehem?
I didn’t until I saw a new film, Open Bethlehem, by a Palestinian woman, Leila Sansour. A Christian, she was born and raised there, and then, like many others, went off to the West. Her father’s death drew her back and she found her home town cowed and shattered by aggressive Israeli anti-terrorism measures.
Huge walls are being built, homes and old businesses confiscated, human rights trampled. An old man died broken-hearted after his beloved shop was bulldozed. Church leaders watch helplessly. Sansour’s poignant film is both a recovery of her own memories and a cry against the lock-up of Jesus’s birthplace.
Good people rightly condemn the persecution of Christians by hardline Muslims and Hindus. But as Israel strangles the life out of Christianity’s holiest site, nobody dares speak out. This woman has. Go to her website, join her campaign. It could be the noblest thing you do this Christmas.

A Record of Hugo Chavez - RIP


by ARVIND SIVARAMAKRISHNAN in the hindu

Hugo Rafael Chávez Frias, President of Venezuela, who died on March 5, 2013 at the age of 58, was a defining figure in Latin American politics for fifteen years, becoming almost synonymous with the popular tide that has elected and reelected left and centre-left governments across the continent in that time.
Mr. Chávez combined courage with immense conviction. Born to schoolteacher parents in Sabaneta in 1954, he qualified in military arts and sciences at the National Military Academy, became an officer in a paratrooper unit, and started his political career in the early 1980s by founding a secret organisation, the Revolutionary Bolivarian Movement, which took its name from the Latin American independence leader Simón Bolivar. His first big move was an attempted military coup in 1992, for which he was imprisoned for two years before being pardoned.
Yet ordinary people’s suffering under austerity measures led Mr. Chávez’s fellow officers to try again, in November 1992; they failed. Mr. Chávez, however, renamed his group the Movement of the Fifth Republic, which later merged with other groups to form the United Socialist Party of Venezuela (PSUV), and won the 1998 presidential election on a socialist manifesto, promising millions relief from a system which had put oil wealth into luxurious lives for the rich and profits for the oil corporations.
Mr. Chávez removed corrupt military officers and started a national reform programme. Venezuela, according to the United States Department of Energy and a former CIA oil expert, has the world’s largest oil reserves at 1.36 trillion barrels, and the new president promptly nationalised the main oil company, Petróleos de Venezuela (PDVSA), putting the profits into very effective social programmes. Carles Mutaner, Joan Benach, and Maria Paez Victor note in CounterPunch that between 2000 and 2010 social spending increased by 61 per cent or $772 billion; the country has the region’s lowest level of inequality, with a reduction in its Gini coefficient of 54 per cent. Poverty is down from 71 per cent in 1996 to 21 now, and extreme poverty is down from 40 per cent to 7.3. The programmes, or Misiones, have reached 20 million people, and 2.1 million have received senior citizens’ pensions, a sevenfold increase under Mr. Chávez.
The country has also cut food imports from 90 per cent to 30 per cent of its consumption, and has reduced child malnutrition from 7.7 per cent in 1990 to 5 today; infant mortality has declined from 25/1000 to 13 in the same period, and the country now has 58 doctors per 10,000 people (as against 18 in 1996). As many as 96 per cent of the population now have access to clean water, and with school attendance at 85 per cent, one in three Venezuelans is enrolled in free education up to and including university.
Oil royalties help. A 2001 law cut foreign companies’ share of the sale price from 84 to 70 per cent, and they now pay royalties of 16.6 per cent on Orinoco basin heavy crude; they used to pay 1 per cent. Exxon and Conoco Philips rejected these terms, as Deepak Bhojwani says in the Economic and Political Weekly (December 22, 2012), and were expelled, but Chevron stayed.
Mr. Chávez of course infuriated the mainly white elites, some of whom talked of him in racist terms, as well as the United States government and press, both of which have consistently vilified him in language bordering on the delusional. The State Department greeted the 2002 coup against Mr. Chávez by expressing solidarity with the Venezuelan people and looking forward to “working with all democratic forces in Venezuela.” The statement also said Mr. Chávez had dismissed the Vice—President and Cabinet. In fact it was the coup figurehead, Pedro Carmona Estanga, who, according to the Notable Names Database NNDB, dissolved the national assembly, disbanded the supreme court, closed the attorney—general’s and comptroller’s offices, and repealed 48 redistributive laws meant to help the poor.
Yet huge public support for Mr. Chávez meant the regime collapsed within days. The President was reinstated, but the then U.S. National Security Adviser Condoleezza Rice hectored him to “respect the constitution”, and Greg Palast points out in The Progressive that in 2006 the Bush administration’s National Security Strategy called him a demagogue out to undermine democracy and destabilise Venezuela.
The U.S. press dutifully played its part. In September 2012, the WorldNet columnist Drew Zahn called Mr. Chávez a “socialist dictator”, when the President was about to win a fourth successive election. All those elections were of far greater probity than the respective U.S. presidential elections of 2000 and 2004; this time Mr. Chávez won by 11 percentage points on a turnout of 80 per cent. Other U.S. media bodies have spread partial truths about the Caracas government, saying it bloats the public sector and lets the budget deficit spiral. In fact, as Mark Weisbrot notes in the Guardian, 18.4 per cent of Venezuela’s work force is in the public sector, in contrast to Norway’s 29 per cent, and its 2012 budget deficit, projected at 51.3 per cent of GDP, is lower than the European Union average of 82.5 per cent; inflation has declined too, from 27 per cent in 2010 to 19 per cent now. Weisbrot also points out that the New York Times — which welcomed the coup — has taken 14 years, longer even than other American media outfits, to publish any arguments for Mr. Chávez. Carles Mutaner and colleagues comment that U.S. analysts ask what Venezuela will do when the oil runs out, but do not ask that about other oil exporters like Saudi Arabia and Canada; neither do critics note that the country’s interest payments are only about 3 per cent of export earnings.
One of Washington’s problems is that, as Greg Palast recognises, Mr. Chávez kept oil revenues within Latin America; unlike Saudi Arabia, which buys U.S. treasury bills and other assets, Venezuela at one point withdrew $20 billion from the U.S. Federal Reserve, and since 2007 has aided other Latin American countries with $36 billion, most of which has been repaid back. In effect, this supplants the International Monetary Fund (IMF) and possibly also its neoliberal fellow—crusader the World Bank. Even more unpalatably for Washington, Chávismo is now a clear political programme towards a Bolivarian Revolution, which Palast calls a close replica of Franklin Roosevelt’s New Deal, with progressive income tax, public works, social security, and cheap electricity. For Bolivarians, such things are rights; they are even reminiscent of T.H. Marshall’s view that they are integral to substantive citizenship. Worst of all for U.S. regional hegemony, Mr. Chávez himself said Venezuela is no longer an oil colony, that it has regained its oil sovereignty, and that he wanted to replace the IMF with an International Humanitarian Bank based on cooperation; Uruguay already pays for Venezuelan oil with cows. Mr. Chávez wished the IMF and the World Bank would “disappear”, and his passionate concern for Latin American countries’ sovereignty made him a decisive figure in the 2011 creation of the Community of Latin American and Caribbean States (Celac).
Mr. Chávez could be ruthless; in 2010 a military court sentenced his former key ally Raúl Isaias Baduel to just under eight years for embezzlement after a long—delayed trial, and Baduel is now banned from future political office, almost certainly because he criticised constitutional reforms which would allow a president more than two terms. Mr. Chávez was, however, no doctrinaire leader. Although a Christian, he criticised clerical collusion with the ancien régime, and did not accept the Church’s authority in politics. He also thought seriously about political economy. Bhojwani notes that he favoured a form of 21st century socialism partly derived from the work of Heinz Dieterich Steffan. For Mr. Chávez, ethics, morality, cooperativism, and associationism make for strong public economic activity and in turn protects the equality which is essential to liberty; it even includes a respect for private property.
The Venezuelan electorate have repeatedly endorsed this; in the December 2012 gubernatorial elections — the first ones in 14 years in which Mr. Chávez himself did not campaign — Mr. Chávez allies won 20 out of 23 states. After the President’s win in October, Argentina’s President Cristina Fernández de Kirchner had sent him a message saying, “Your victory is also ours.” Billions, and not only poor people, around the world would agree: Tu victoria es también la nuestra.
