Bacteria and Obesity

Two mice; the mouse on the left has more fat s...

Guess which mouse has the bacteria inside it.

 

Here is a story that might make you feel better about eating too much at Christmas get togethers. According to a study in China, it isn’t how much we eat or how little we exercise that makes us fat, it is what bacteria we have in our colons. I found the article in the Financial Times through Instapundit.

 

Obesity in human beings could be caused by bacterial infection rather than eating too much, exercising too little or genetics, according to a groundbreaking study that could have profound implications for public health systems, the pharmaceutical industry and food manufacturers.

The discovery in China followed an eight-year search by scientists across the world to explain the link between gut bacteria and obesity.

Researchers in Shanghai identified a human bacteria linked with obesity, fed it to mice and compared their weight gain with rodents without the bacteria. The latter did not become obese despite being fed a high-fat diet and being prevented from exercising.

 

Personally, I think that diet and exercise might have a little to do with obesity. If this study proves to have merit than it might pave the way to more effective weight loss methods. This isn’t the only article I have read indicating that human intestinal bacteria might have a profound impact on our health and clearly a lot more research needs to be done in this field.

 

Here is a sentence in the middle of the article that ought to make anyone think for a minute.

 

Governments around the world are grappling with an obesity pandemic.

 

Do you know how truly weird it is that governments around the world have to deal with obesity. It wasn’t that long ago that the major preocupation of most governments was preventing their citizens from starving. The fact that a large portion of the population of the world may suffer from having too much food is simply unprecedented in human history and represents a triumph of man over nature, if not an entirely unprobematic one.

 

 

 

The Nativity According to Luke

December 22, 2012

Here is what Christmas is all about

 

Linus quotes from the Gospel according to Luke. There are two accounts of Jesus’s birth in the New Testament, the account that Luke gives and the account that Matthew gives. Mark ignores the question of Jesus’s birth entirely, preferring to begin with Jesus’s public ministry while John actually begins his account before the nativity and moves from there to Jesus’ career. Here is Luke’s account.

In those days Caesar Augustus issued a decree that a census should be taken of the entire Roman world. (This was the first census that took place while[a] Quirinius was governor of Syria.) And everyone went to their own town to register.

So Joseph also went up from the town of Nazareth in Galilee to Judea, to Bethlehem the town of David, because he belonged to the house and line of David. He went there to register with Mary, who was pledged to be married to him and was expecting a child. While they were there, the time came for the baby to be born, and she gave birth to her firstborn, a son. She wrapped him in cloths and placed him in a manger, because there was no guest room available for them.

And there were shepherds living out in the fields nearby, keeping watch over their flocks at night. An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. 10 But the angel said to them, “Do not be afraid. I bring you good news that will cause great joy for all the people. 11 Today in the town of David a Savior has been born to you; he is the Messiah, the Lord. 12 This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger.”

13 Suddenly a great company of the heavenly host appeared with the angel, praising God and saying,

14 “Glory to God in the highest heaven,
and on earth peace to those on whom his favor rests.”

15 When the angels had left them and gone into heaven, the shepherds said to one another, “Let’s go to Bethlehem and see this thing that has happened, which the Lord has told us about.”

16 So they hurried off and found Mary and Joseph, and the baby, who was lying in the manger. 17 When they had seen him, they spread the word concerning what had been told them about this child, 18 and all who heard it were amazed at what the shepherds said to them. 19 But Mary treasured up all these things and pondered them in her heart. 20 The shepherds returned, glorifying and praising God for all the things they had heard and seen, which were just as they had been told.

21 On the eighth day, when it was time to circumcise the child, he was named Jesus, the name the angel had given him before he was conceived.(Luke 2:1-21)

There is a considerable amount of skepticism regarding the census, both on the dating and the procedure. Most skeptics regard it as extremely improbable that the Romans would make people travel here and there to register in their home towns. As a matter of fact that is just how the Romans conducted their censuses.

Every five years, each male Roman citizen had to register in Rome for the census. In this he had to declare his family, wife, children, slaves and riches. Should he fail to do this, his possessions would be confiscated and he would be sold into slavery.
But registration meant freedom. A master wishing to free his slave needed only to enter him in the censor’s list as a citizen (manumissio censu).
Throughout the entire republican era, registration in the census was the only way that a Roman could ensure that his identity and status as a citizen were recognized. Fathers registered their sons, employers their freedmen.
Primarily the census served to count the number of citizens and to assess the potential military strength and future tax revenue. Most important, the census transformed the city into a political and military community.
But the census performed a highly symbolical function. To the Romans the census made them more than a mere crowd, or barbarian rabble. It made them a populus, a people, capable of collective action.
To the Roman the census was one of the foundation stones of their civilization.

As the Roman Empire expanded and citizenship was given out to other cities in Italy and around the Mediterranean, I would imagine that every Roman citizen had to go to his native city to register. Presumably there were lists of citizens kept in major cities and in Rome. Paul claimed to be a Roman citizen at various times in Acts and you might wonder how he was able to prove it. Well, every Roman citizen had a sort of ID or diploma which would have been issued in his city.

But with the steady extension of the citizenship by individual grants to provincials isolated in peregrine communes, and with the informal settlement of large numbers of Italian immigrants in the provincial territories, a more effective means of registration became necessary. Formal documentation of the grant of citizenship to provincial soldiery appears first in 89 B.C., in the shape of a bronze tablet recording the decree of a proconsul enfranchising a unit of Spanish cavalrymen in the Social War, who are all named in a general list. Presumably each soldier received a copy. The cities of persons of higher status enfranchised by Octavian in c. 40 B.C. received a copy of a decree detailing all the privileges of their new status, while his auxiliary veterans could acquire copies of the enabling edict that enfranchised them. But it is only with the regularization of the grant of citizenship to the all time-expired auxiliaries by Claudius that a standardized document appears. This is the small bronze diptych known as the diploma civitatis, containing a brief and uniform formula conferring the Roman citizenship on the holder and his descendants, who is indicated by his name and military unit. These documents were not normally used for civilians, who received instead a copy in libellus form of the brief imperial warrant authorizing the registration of their enfranchisement in the archives at Rome.

Diplomata and libelli provided for new citizens. For the mass of the citizenry, for whom censorial registration at five-yearly intervals was an inefficient instrument, adequate provision was finally made by the creation of an official system of compulsory birth registration under the social legislation of Augustus (A.D. 4)… The Roman citizen was required to register the birth of his children within thirty days before a Roman official, and he received a wooden diptych recording the declaration, which acted as a certificate of citizenship for the child for the rest of his life. Like the military diplomata this contained the names of seven witnesses, and provided a presumptive proof of citizen status… Similarly the enfranchisement of freedmen, which depended upon a formal act, was recorded in a documentary tabella manumissionis. Citizens of diverse origins thus came to have some form of documentary evidence of their status.

Presumably Paul registered at Tarsus while he lived there. To get back to the census, obviously, Joseph wasn’t a Roman citizen and Judea was under the rule of Herod, not the Romans. The census could have been a small time affair, the mention of Caesar Augustus being either an exaggeration or a long-standing policy of Augustus to encourage the provinces to conduct censuses, but conducted according to Roman norms, with every resident registering in his home town. You must not imagine, however, large crowds of people traveling to and fro. Remember that in this time most people would have lived their whole lives in the same village. Joseph’s journey from Nazareth to Bethlehem would have been very much an exception. The only thing really odd about this account was his taking Mary with him. There would have been no need for her to travel. As a woman, her residency would not have mattered much.
