Tessa Ogle, The Conversation

There are so many dos and don’ts associated with pregnancy it can be hard to keep up with them. Coffee is an everyday staple for many people, so it is not surprising women seek reassurance this stimulant is safe during pregnancy.

With guidelines differing between and within countries it can be tricky to assess the risks of having a coffee or two.

We asked five experts whether it’s OK to drink coffee while pregnant.

Four out of five experts said yes

But they all had a pretty big caveat. It’s safe provided it’s consumed in moderation.

It’s also important to remember things like tea, chocolate and energy drinks also contain caffeine, so you’ll need to take that into account when estimating your daily intake.

Here are the experts’ detailed responses:

Research Check: can drinking coffee help you lose weight?



As keen as we may be to hear about any health benefits of drinking coffee, the headlines aren’t always what they seem.

Researchers from the University of Nottingham in the UK recently published a study in the journal Scientific Reports suggesting caffeine increases brown fat.

This caught people’s attention because brown fat activity burns energy, which may help with weight loss. Headlines claimed drinking coffee can help you lose weight, and that coffee is possibly even the “secret to fighting obesity”.

Unfortunately, it’s a little more complicated than that. The researchers did find caffeine stimulated brown fat, but this was mainly in cells in a lab.

For a human to reap the benefits seen in the cells, we estimate they’d need to drink at least 100 cups of coffee.

Although part of this research did look at people, the methods used don’t support coffee or caffeine as weight-loss options.

What is brown fat?

Brown adipose (fat) tissue is found deep within the torso and neck. It contains fat cell types which differ from the “white” fat we find around our waistlines.

Brown fat cells adapt to our environment by increasing or decreasing the amount of energy they can burn when “activated”, to produce heat to warm us up.

When people are cold for days or weeks, their brown fat gets better at burning energy.

We understand caffeine may be able to indirectly accentuate and prolong some of these processes, mimicking the effects of cold exposure in stimulating brown fat.

Brown fat – and anything thought to increase its activity – has generated significant research interest, in the hope it might assist in the treatment of obesity.

What did the researchers do in this latest study?

The research team first conducted experiments where cells taken from mice were grown into fat cells in petri dishes. They added caffeine to some samples, but not others, to see whether the caffeinated cells acquired more brown fat attributes (we call this “browning”).

The dose of caffeine (one millimolar) was determined based on what would be the highest concentration that browned the cells but didn’t kill them.

The fat cell culture experiment showed adding caffeine did “brown” the cells.

The researchers then recruited a group of nine people who drank a cup of instant coffee, or water as a control.

Before and after the participants drank coffee, the researchers measured their brown fat activity by assessing the temperature of the skin near the neck, under which a major region of brown fat is known to lie.

Skin temperature increased over the shoulder area after drinking coffee, whereas it didn’t after drinking only water.

How should we interpret the results?

Some people will criticise the low number of human participants (nine). We shouldn’t make broad recommendations on human behaviour or medicine based on small studies like this, but we can use them to identify new and interesting aspects of how our bodies work – and that’s what these researchers sought to do.

But whether the increased skin temperature after drinking coffee is significant cannot be determined for a few important reasons.

Firstly, although the study showed an increase in skin temperature after drinking coffee, the statistical analysis for the human experiment doesn’t include enough data to accurately compare the coffee and water groups, which prevents meaningful conclusions. That is, it doesn’t use appropriate methods we apply in science to decide if something really changed or only happened by chance.

Enjoy coffee for the taste, or the buzz. But don’t expect it to affect your waistline.

Second, measuring skin temperature is not necessarily the most accurate indicator for brown fat in this context. Skin temperature has been validated as a way to measure brown fat after cold exposure, but not after taking drugs which mimic the effects of cold exposure – which caffeine is in the context of this study.

Myself and other researchers have shown the effects of these “mimic” drugs result in diverse effects including increased blood flow to the skin. Where we don’t know if changes in the skin temperature are due to brown fat or unrelated factors, relying on this measure may be problematic.

Although also suffering its own limitations, PET (poistron emission tomography) imaging is currently our best option for directly measuring active brown fat.

It’s the dose that matters most

The instant coffee used in the study contained 65mg of caffeine, which is standard for a regular cup of instant coffee. Brewed coffees vary and might be double this.

Regardless, it’s difficult to imagine this dose could increase brown fat energy burning when studies using large doses of more potent “cold-mimicking” drugs (such as ephedrine) cause no, or at best modest, increases in brown fat activity.

Health check: can caffeine improve your exercise performance?


But let’s look at the caffeine dose used in the cell experiments. The one millimolar concentration of caffeine is a 20-fold larger dose than 300-600mg of caffeine dose used by elite athletes as a performance-boosting strategy. And this dose is five to ten times higher than the amount of caffeine you’d get from drinking an instant coffee.

Rough calculations therefore suggest we’d need to drink 100 or 200 cups of coffee to engage the “browning” effects of caffeine.

So people should continue to drink and enjoy their coffee. But current evidence suggests we shouldn’t start thinking about it as a weight loss tool, nor that it has anything meaningful to do with brown fat in humans. – Andrew Carey


Blind peer review

This Research Check is a fair and balanced discussion of the study. The limitations identified by this Research Check apply equally to diabetes, which the study encompassed, but didn’t get picked up as much in the headlines.

Coffee contains more than caffeine, and while there is some evidence that modest coffee consumption may reduce diabetes risk, decaffeinated coffee seems to be as effective as caffeinated coffee. This is consistent with the point made by the Research Check that you would need to drink an implausible number of cups of coffee to produce the effect seen with caffeine in the cultured fat cells. – Ian Musgrave


Research Checks interrogate newly published studies and how they’re reported in the media. The analysis is undertaken by one or more academics not involved with the study, and reviewed by another, to make sure it’s accurate.The Conversation

Attacks on Christians in Karnataka Frequent, Furious


Southern state has become epicenter of religious assaults, Christians say.

NEW DELHI, February 4 (CDN) — Karnataka state recorded the highest number of anti-Christian attacks in India last year, and it is keeping pace this year.

Christians in Karnataka are being attacked “at rapid regularity” and “with near impunity,” and it is “a serious matter of concern for the Christian community,” said Dr. Babu Joseph, spokesperson of the Catholic Bishops’ Conference of India (CBCI).

Much of the violence occurs under the vigilante pretext of rounding up Christians supposedly involved in “forcible” or “fraudulent” conversion efforts. On Monday (Feb. 1) in Thagadur village, Kodagu district, Hindu extremists dragged 11 Christians – including four women – from their homes and colluded with police to arrest them on such false charges.

The Global Council of Indian Christians reported that all of the Christians, members of the Beraka Gospel Church in Suntikupa village, were tortured at the Siddapur police station to pressure them to admit to the charges. Most of the jailed Christians are tribal, daily wage laborers who work on coffee plantations.

Police denied torturing the Christians, but like many people in India easily confused by Hindu extremist propaganda, Inspector Ratan Singh of the Siddapur police station seemed to erroneously believe that laws against fraudulent conversion apply to any kind of proclamation of faith.

“According to the complaint we received, the accused were inviting local Hindus for prayer meetings to convert them,” Singh told Compass, as if such activity were illegal in India. “We did not beat them. When they were produced before the judicial magistrate, they said they were not mistreated by the police.”

The GCIC recorded 72 attacks on Christians in Karnataka in 2009. That represents a decline from the 112 attacks the previous year, when three months of anti-Christian violence in Orissa state’s Kandhamal district in 2008 led Hindu extremists in Karnataka to lash out as well, according to Christian leaders.

Justice Michael F. Saldanha, a retired judge of the Karnataka High Court and president of the Catholic Association of South Kanara (a district in Karnataka also known as Dakshina Kannada), told Compass that attacks on Christians in the state increased after the Bharatiya Janata Party (BJP) began to rule.

In May 2008 the BJP came to power in Karnataka, thus making it the first southern state with a stand-alone BJP government in the history of India. The party’s rule was preceded by a 20-month rule in alliance with a local party, the Janata Dal (Secular).

Although Karnataka has had a dominant presence of the Hindu extremist Sangh Parivar since 1950, its cadres obtained free rein only after the BJP’s electoral victory, Saldanha explained.

“The real headquarters of the Sangh Parivar is not in Maharashtra [official headquarters of the Hindu extremist Rashtriya Swayamsevak Sangh, or RSS, in Nagpur), it’s in Karnataka,” said Saldanha, who conducted a private inquiry into a series of attacks that rocked Karnataka in September 2008 following the unprecedented anti-Christian bloodbath in Orissa state’s Kandhamal district.

Between Aug. 17 and Sept. 21, 2008, more than 28 attacks on churches, led mainly by the Hindu extremist Bajrang Dal, a Sangh Parivar offshoot, were reported from various parts of Karnataka.

Saldanha pointed out that Brahmins, the highest or priestly class in the caste hierarchy in Hinduism, from Udupi district and Mangalore city in neighboring Dakshina Kannada district played a special role in leading the Hindu right-wing movement. The retired judge also accused the BJP government of supporting Sangh Parivar outfits with public money.

“The Karnataka government gives money to right-wing groups for festivals in the name of celebrations, and also through donations to certain temples,” he said.

Agreeing with Saldanha, the CBCI’s Joseph said the violence in Karnataka points to a “decline in civility and collapse of administration.”

“It is indeed sad that Karnataka, which enjoyed communal harmony and social amity for so long, has recently been pushed into the cycle of hate crimes perpetrated by the extreme elements in society that do not believe in mutual tolerance or acceptance,” Joseph said.

Karnataka Gov. H.R. Bhardwaj reportedly said earlier this week that protection of people’s lives and liberties, including the right to propagate their religion, was “the essence of Indian democracy.”

The governor said it was the responsibility of the state government “to see that nobody is allowed to flout the democratic norms and laws of the land,” acknowledging a rise in the incidence of attacks against churches, reported Daijiworld.

His comments came a day after an attack on a glass painting of the Virgin Mary at the entrance arch of the Canara Organisation for Development and Peace building in Nantoor area on Saturday (Jan. 30).

On that day Christians held a silent protest in Mysore, and on Monday (Feb. 1) Christians in Mangalore protested in like fashion against increasing attacks on them.

On Jan. 28, unidentified people burned down a church in Raipura area in Molakalmuru town in Chitradurga district. The Jesus Loves Holy Temple Church turned into ashes, reported GCIC.

Two Catholic churches were attacked in Mysore and Uttara Kannada districts on Jan. 25. Unidentified people reportedly broke a statue of Mary on the compound wall of the Holy Family Church in Hinkal village in the wee hours in Mysore district. In the other incident, glass panes covering the statue of Mary were broken at St. Anthony Church in the Pernamakki area in Uttara Kannada district.

At 2:30 a.m. this morning, unidentified people broke into a Catholic church and vandalized it in the Malavalli area of Mandya district, reported the Karnataka-based GCIC. The cross, statues and musical instruments in the St. Mathias Church were destroyed, it said, adding that the parish priest filed a complaint at the Malavalli police station.

‘Lip Service’

Echoing claims of the Hindu nationalist BJP, Karnataka State Minorities Commission member Anthony Fernandez said he does not believe there is any reason for concern.

“Some elements are simply trying to tarnish the image of the state government,” he said.

Fernandez acknowledged, however, that the Hindu nationalist Sri Ram Sene (Army of God Rama) was involved in some attacks. The Sri Ram Sene is believed to be a splinter group from the Sangh Parivar family of organizations under the RSS.

Karnataka Chief Minister B.S. Yeddyurappa on Jan. 28 warned those who vandalize religious places, saying he would have their hands “chopped off.”

“I, the chief minister of Karnataka, am saying I will chop off their hands,” Yeddyurappa was quoted as saying by Headlines Today news channel.

The CBCI’s Joseph said “lip service” by the government was “no longer enough.”

“It has to show results on the ground that it means business in tackling the menace of communal elements,” he said. “Unprovoked violence against fellow citizens in the name of religion is pernicious, and it must stop forthwith, or else the impression may gain ground that the administration of the day is colluding with criminal and extreme elements in vitiating the social harmony for short term political gains – something this country can ill afford in the long run.”

Prisoners Freed in Acteal, Mexico Case Yet to Return Home


 

Christians bear no grudges, fear no threats from accusers.

TUXTLA GUTIERREZ, Mexico, October 12 (CDN) — Alonso Lopez Entzin, a Tzotzil-speaking Christian in Chiapas state, Mexico, spent 11 years and eight months in prison for a crime he did not commit. Accused of participating in the tragic “Acteal massacre” in December 1997 in which 45 persons died near San Cristobal de las Casas, he and more than 80 of his neighbors were summarily arrested and charged with the murders.On Aug. 12, the Federal Supreme Court of Mexico ordered that Lopez Entzin and 19 other indigenous men accused in the Acteal killings – 18 are Christian, including Lopez Entzin – be freed from El Amate Penal facility in Chiapas. Their release came as a surprise to him and his fellow prisoners, as well as to thousands of people in Mexico and around the world advocating their release.

Of the 18 Christians released, only five were Christians when they were arrested; the rest came to trust in Christ while in prison. At least 27 innocent men who were Christians at the time of their arrest remain in prison, according to advocacy organizations.

“I thank God that I have been granted freedom,” Lopez Entzin told Compass. “We are no longer imprisoned thanks to the power of God. There is no other person that has this kind of power, only God.”

The court is reviewing the cases of another 31 men convicted in connection with the massacre. Six more defendants will be granted new trials.

“Right now we see the first fruits of our prayers,” said Tomas Perez Mendez, another of the 20 freed prisoners. “We are confident in the Lord that the rest of the brothers are going to obtain their freedom as well.”

Lopez Entzin added that winning their freedom will not be easy.

“When we were inside El Amate, we began to pray, fast and glorify our Lord Jesus Christ. There are thousands and thousands of brothers who prayed for us inside the jail – thank God He answered those prayers,” he said through tears. “That’s why those brothers who remain behind in El Amate believe that if God’s will is done, they will soon be free.”

Most of the remaining Acteal inmates are evangelical Protestant Christians sentenced to 25- and 36-year prison terms. For years, human rights advocates and legal experts have presented legal arguments showing that the men were convicted on dubious evidence. The district court of the state of Chiapas, however, has consistently ruled against the defendants in appeals.

Attorneys for the defendants finally succeeded in bringing the case before the Federal Supreme Court in Mexico City. The justices who reviewed the case found clear violations of due process and on Aug. 12 overturned the convictions in a 4-1 decision.

The court ruling stated that the decision was not a determination of the guilt or innocence of the men, only that their constitutional rights had been violated during their arrest and conviction.

Though grateful to be free at last, Agustin Gomez Perez admitted that prison was “very difficult, very difficult indeed.”

“There inside the jail, everybody loses,” Gomez Perez said. “I saw it. Many lost their wives, their families, their homes. In the years I was in jail I lost my son. It was May 7, 2005. Twelve families were traveling in a truck to visit us in El Amate. They had an accident, and my 3-year-old son Juan Carlos was killed.”

Inmates expressed gratitude for church groups and international organizations that lent support to their families during their incarceration. Some groups supplied chicks, piglets and coffee plants for wives and children to raise on family plots. A volunteer team of doctors and nurses from Veracruz provides free treatment to prisoners and their dependents.

The prisoners said that one of the greatest helps was regular visits from their families. International Christian organizations raised money for bus fares and chartered vehicles to ensure that the prisoners’ families, who could not otherwise afford the travel, saw their husbands and fathers as often as possible.

Normalcy Not Returned

Despite being freed, the 20 men have yet to resume normal life with their families.

“When I left jail, I didn’t think I would be stuck half-way home,” Gomez Perez said. “I was thinking I would come home and see my wife and children. But we haven’t got there. We are left here half-way home.”

“Half-way home” for the released men is the market district in hot, bustling Tuxtla Gutierrez. They are living in makeshift half-way houses provided by the federal government, awaiting resettlement on land that state authorities have promised them.

Compass met with seven of the former inmates in a rented building they occupy with their wives, children and, in some cases, grandchildren. The families share windowless, sparsely furnished rooms with bare cement floors. Government food rations sustain them. While the half-way house is better than prison, it is nothing like the lush, green Chiapas mountains to which they long to return.

The men agreed to the relocation scheme because the farms they worked before going to prison have long since reverted to their heirs or, in some cases, neighbors. They welcome the assistance to get back on their feet financially.

Government officials, however, insist that the Acteal prisoners must relocate to new communities because they fear violent clashes will flare between them and their old rivals.

The seven freed men were unanimous in their opinion that such confrontations would not happen.

“In the first place, we do not agree with what the government is saying,” Gomez Perez said. “We hold no grudges against those who accused us. What happened, happened. We are not thinking vengeance.”

Perez Mendez agreed with Gomez Perez that the men feel no ill will against those who accused them and no resentment for what they suffered in jail.

“God does not want that we hold grudges or take vengeance against anyone,” he said. “There is not really much danger out there in our communities either. When people saw the news on television on Aug. 12 that we were getting out, they were happy. Well, now we hear that they found out we are not coming home, that we are here in Tuxtla, and some are saying, ‘Why don’t they come home? Tell them to come.’”

The Acteal prisoners have reason to hold grudges. Their attorneys say many of them were arrested in random police sweeps in the days following the massacre simply by being in the wrong place at the wrong time. Public indignation over the brutal slayings, fueled by numerous inflammatory press releases from Las Abejas, a civic group whose members were primary targets in the massacre, as well as by the left-leaning human rights organization Fray Bartolomé de las Casas, swelled to fever pitch in December 1997.

Authorities responded by arresting dozens of “suspects,” without evidence or warrants, to quell the outcry.

Some Acteal defendants found themselves accused of the crime by allies of the rebel Zapatista guerrilla army. A land dispute between Zapatista sympathizers and opponents of the rebels intensified during the waning months of 1997, claiming the lives of 18 indigenous men, the majority of them Protestant Christians. Attorneys say indifferent law enforcement officers failed even to investigate the murders, let alone arrest the perpetrators.

Frustrated with the authorities’ foot-dragging and desperate to defend themselves against further aggression, nine indigenous young men armed themselves and confronted their enemies on Dec. 22, 1997. The ensuing firefight and subsequent massacre at the Catholic hermitage in Acteal ended with 45 dead, many of them women and children who were participating in an Abejas-sponsored program that day.

Five of the nine armed men have confessed to participating in the Acteal shootings and insist they acted alone. Those five are serving prison terms in El Amate. Two others were arrested and released because they were minors at the time of the crime. Two more remain at large and, ironically, have reportedly come under the protection of the Zapatistas.

Las Abejas and its allies continue to assert that that the Acteal killings were carried out by “paramilitary” units equipped and assisted by the Mexican army. With the passage of time, many of those who hold this thesis have admitted that most of the Acteal prisoners did not, in fact, participate in the shooting. Nevertheless, they insist that until the “intellectual authors” of the atrocity come forward and confess, not one prisoner – even though innocent of the crime – should be released.

That strange logic has helped to keep more than 50 innocent men in prison for nearly 12 years.

“It is certain that we suffered an injustice for nearly 12 years,” Perez Mendez said. “A lot of people tell us that we are guilty. But as far as we are concerned, God knows all. We did not commit that crime.

He implored Christians to pray for the innocent men who have yet to be released.

Pray as well for we who are not at home in our communities,” he said. “I ask that you not forget us.”Report from Compass Direct News 

Sodom found? The quest for the lost city of destruction – Part 1


By Brian Nixon

Special to ASSIST News Service

I met Dr. Steven Collins in the reception area of Trinity Southwest University in Albuquerque, where he serves as provost and professor. Instead of staying at the school, we headed off to a local coffee shop.

Dr. Collins didn’t look like your average jet-setting archeologist: no Indiana-Jones leather jacket, hat, or whip. Instead, Steve wore jeans, sandals, and a “Life is Good” t-shirt. And for Steve, that motto is playing out in his own life.

With his newest discoveries in Jordan, life is turning out very good for the unassuming archeologist from New Mexico.

I first got word of his recent finding at Calvary of Albuquerque, where Steve sat down for an interview with Senior Pastor, Skip Heitzig. Steve brought some convincing evidence of a monumentally significant find. Dr. Collins contends that he may have discovered the historic city of Sodom.

Steve told me in our interview that his interest in the location of Sodom began in 1996. Then, Steve was working on a dig in the West Bank north of Jerusalem, the site of biblical Ai, but was also leading archeology tours in the Near East.

It was on one of these trips that Steve began to question the traditional site of Sodom, what is known as the “Southern Theory.” This theory attributes the site of Sodom to the southern region of the Dead Sea.

“I began to read Genesis 13-19, and realized that the traditional site did not align itself with the geographical profile described in the text,” Steve told me.

“Now let me say,” he continued, “that many scholars don’t have a high view of Scripture. Some even frown upon using biblical texts as a tool for location designation. My philosophy is that the text is generally reliable and can—and should—be used (at bare minimum) as a basic guide for a geographical profile.”

“When I read how the author of Genesis described the area of Sodom and then looked at the area of the traditional site in the Southern region, I said: ‘This cannot be the place. There are too many differences of description.’

“Sadly, because of my work at the site of Ai, I was unable to really investigate and do research on my initial thoughts. So I let it sit for over five years.”

The geographical point at issue, according to Steve, is how the text in Genesis describes the region of the Kikkar, understood as “the disc of Jordan.”

Dr. Collins continued, “When the Bible uses the description of Kikkar, it is only referring to the circular region of the Jordan Valley east of Jericho and north of the Dead Sea.”

“This region is the breadbasket of the area, full of freshwater and farmland,” he explained. “All of this is interesting to me because Kikkar can also mean “flat bread,” like a tortilla here in New Mexico.”

So what’s the issue?

According to Collins, “The traditional “Southern Theory” site of Sodom does not have the geographical parallels described in the text. Namely: 1. One can see the whole area from the hills above Jericho (Bethel/Ai), 2. It must be a well-watered place (described, “like Egypt.”), 3. It has a river running through it (the Jordan), and 4. It must follow the travel route of Lot” (who went to the other side of the Jordan, eastward, away from Jericho.)

Though the traditional site does not have any of these geographical indicators, the site in Jordan, Tel-al-Hamman, does. How did Dr. Collins become aware of this site? That is a fascinating story in and of itself—which we’ll turn to in Part 2.

Report from the Christian Telegraph

ANOTHER GIMMICK: Text Messaging Questions to the Preacher during the Sermon


Is this a gimmick or a legitimate innovation for preaching? During sermons, the Rev. Mike Schreiner of Morning Star Church (United Methodist denomination), allows text messages to be sent off – to him that is, with questions relating to the sermon.

The so-called ‘Director of Worship,’ Amie Haskins, receives the messages on the church mobile phone. These she screens and then types questions into a keyboard to be sent via a computer connected to Schreiner’s lap top in the pulpit.

With the questions appearing on his screen, this allows Schreiner the ability to answer relevant questions during the sermon.

The text messaging also engages the young people of the church and they listen more intently than they did before.

The text messaging is part of the wider ‘technological ministry’ operating at the church, which includes lighting controls, presentations on the large screens above the stage, wide-screen plasma monitors in the church’s coffee shop in the lobby, etc.

Apparently the texting fad is taking off across the US and is even used to some degree in the Mars Hill Church at Seattle.

Part of the philosophy behind the texting fad seems to be to be more appealing to people so that they come to church and get more involved in what is actually happening. Undoubtedly this would be an attractive and seemingly successful method for getting people involved and coming along, especially those who love their gadgets these days.

I am sure that texting has its place in the ministry of any modern church and can prove very useful to send messages to large numbers of people at once and for keeping in touch, however, the use of texting in the local church context seems to me to be out of place.

Preaching ought not to be confused with teaching, with the two being different aspects of a church’s ministry. Certainly any true preaching will include teaching, but teaching need not include preaching. Preaching is the authoritative declaration of the Word of God to the people of God by the God-called preacher of God. He comes with a message that is to be heard by the people of God for the people of God. The message is not to be tailor made to the felt needs of the people sitting in the congregation nor is it to be modified to suit the desires of those sitting there as expressed via texted questions to the preacher.

The danger is that the preacher will be moved away from his task and go off message to pursue certain tangents that may not even have been the course he intended to take as the messenger of God to the people of God. He comes with the Burden of the Lord and he must speak and be heard as that messenger.

Preaching is a declaration and explanation of the Word with relevant and searching application and as such is not a dialogue, no matter what form that dialogue might take.
