Apple #719: People Leaving Syria

Like most of you, I've been hearing more and more news reports about the refugees who've left Syria.  I was kind of taking it in, kind of not. Then I heard one news report on the radio say that an estimated 5,000 people are leaving per day. Each day.  That number stunned me so much, I decided to find out more.

My big question was, if you were in charge of a country where people were so desperate to leave that 5,000 people each day would rather abandon their homes, the places they grew up, the food and the customs and the music and their friends and their family and their places of worship and the places where family members are buried -- they would rather leave all that, and put themselves in the hands of complete strangers to guide them into completely foreign lands and risk being taken advantage of, kidnapped, raped, or left to suffocate in a truck, or who knows what else -- 5,000 people each day would  rather risk all of that than to stay in your country, wouldn't you start to think that maybe something's wrong with the way you're running your country?

Mm, apparently not if you're the guy in charge of Syria.

I don't want to give you a history of all that's happened in Syria.  Lots of other sources out there have done a much better job of that than I could (see Sources at the end of this entry).  Instead, I'm going to give you some facts here & there that you might not know (I didn't know these things).  Because everybody's saying this is the worst humanitarian crisis since World War II.

In reading about the refugee situation, I discovered I got kind of tone deaf to all the numbers being tossed around. They're all so big, it doesn't take long before they start to get meaningless.  I had to find reference points for those numbers so I could get a picture of just how big they are.  So I'll give you some of those numbers along with the reference points, too.

I know this map is hard to read, and it's outdated from 2012, but my point is the arrows. They're pointing to all countries on all sides of Syria. Meaning that people are taking any and every route possible to get out of the country.
(Map from somewhere on News Aggregator)

The Numbers

  • Syria is about the size of Arizona. 
  • Arizona's total population is about 6.7 million people.
  • Syria's total population -- difficult to estimate given how many people are leaving -- is somewhere around 22 million people.
  • 22 million people is everybody who lives in Florida plus everybody who lives in Iowa.
  • Since 2011 when the civil war started, an estimated 2 to 3 million people have left Syria.  That's somewhere between all of Houston leaving the country, or all of Chicago leaving the country.
  • Millions more people have not left Syria but have been displaced from their homes. This is a nice way of saying their houses got bombed or destroyed, or their farmland was burned, or there's no longer any usable water, or for some other drastic reason they had to leave home and find someplace else to live.
  • That number is estimated to be anywhere from 4 million to 11 million people.
  • 4 million people is all of Los Angeles plus more.  11 million people is all of New York City plus all of Chicago.  Looking for someplace else to live, all at once.
  • Imagine everyone in all the five boroughs of New York leaving their homes and looking for someplace else to live. Because all five boroughs have been bombed or destroyed or have otherwise become unlivable. Oh, plus all of Chicago too.
  • Another way to think of that 11 million is that it equals half of the entire country's population. 

One of the refugee camps specifically for those who have left Syria. This one is in Za'atari, Jordan, as of 2013. The camp is 30,000 square meters and can hold up to 113,000 people. Over 600,000 refugees from Syria have come to Jordan.

What's So Terrible?

  • For that many people to leave, things must be pretty bad.
  • The dude who runs Syria, Bashar Al-Assad, is pissed off and he is bombing his own people.

Looks like your basic nerd, doesn't he, with the sleeves of his jacket too long and everything. He was trained to be an ophthalmologist.  But apparently this is what a desperate villainous dictator looks like.
(Photo from Bashar Al-Assad's personal website)

  • He rules his country in one of those pseudo-democracies that are really dictatorships that also have a religious component.  Since he's in charge, his religion is the only acceptable one to practice, and he denies various rights to or persecutes people who practice religions other than his.
  • His religion is a small branch of Islam (Alawite).  Other Islamic branches which have more people, both in the world and in his country, his government has repressed in some way.  
    • For example, political parties that are allied with one of the unacceptable Islamic religions or some other religion are illegal, and if you're found doing political things associated with those illegal parties, you could be jailed or worse. People have been beaten, kidnapped, disappeared, etc.
  • So in 2011, a bunch of people attempted their own Arab Spring and rebelled against his government.
  • His father used to be in charge of Syria, and when his father faced an uprising from another Islamic group, he dealt with that by destroying entire neighborhoods where that group was centered. I mean, he leveled everything like a tornado.

This is Bashar's dad, Hafez. How many people must suffer because of Bashar's daddy issues?
(Photo from Bashar Al-Assad's personal website)

  • So Bashar tried to do the same thing. He got his army to kill or kidnap or "disappear" the people involved in that revolutionary effort.  But when he tried his dad's technique, it didn't work. His attempt at repression backfired.  It only made the rebels fight back harder.  And then so did he.
  • He's bombed his own cities, he's burned people's farms, he's had people kidnapped or murdered, his army has raped women and killed children, and then of course you remember the sarin gas incidents when he gassed his own people.  
  • He got rid of the sarin after the international community made all kinds of threats, but reports say he's now using chlorine and ammonia.  Plus, he's recently gotten funding from Russia so he's dropping even more bombs -- including barrels full of ammunition dropped from helicopters -- onto places that may or may not house rebel forces.  So he's killing or injuring lots of civilians in the process.
  • Meanwhile, ISIS has seen this chaos and destruction as a prime opportunity for them.  So they've moved into Syria and they're conducting their brutal recruitment tactics with their lovely beheadings and so on, forcing those people whose heads they have not cut off to join them.  
  • Hospitals have been destroyed, water lines have been blown up so there's not much clean water, in some towns there aren't enough people to bury the dead, and as for food, even before the war people were having to smuggle things in through underground tunnels and now those tunnels have been blown up in places so it's very hard to get decent food, or for anyone to deliver supplies to them.

The food aid being given out is not from their own government but from the UN and other relief agencies.

  • There have been attempts at a peace agreement, but the rebels don't believe that Bashar will keep any agreement he makes, so nothing sticks.
  • With no end of the destruction in sight, more and more people are saying, Time to GTFO.

The Initiating Event

  • What triggered all of this?  What was  the event that set all this in motion?  
  • Some teenagers painted revolutionary slogans on a school wall.
  • The teenagers were arrested and beaten and tortured.  Always the appropriate response to graffiti.
  • Demonstrators protested.
  • Government security forces shot at the protestors and killed several.
  • That only led to more demonstrations, and ultimately thousands of people filled the streets demanding Bashar's resignation.
  • But of course Bashar would not give up his power.  Apparently he would rather destroy his entire country than give up his power.
  • All this from some words that some teenagers painted on a wall.  
  • What did they write? "The people want to topple the regime" and "It's your turn, doctor."

This graffiti, painted in 2011 during the initial uprisings, says "Down with Bashar."

Apple #718: Why Am I Hungry if I'm Fat?

Dear Apple Lady,

My body has rather obvious stores of fat available to it. How come when I'm hungry, it doesn't just burn that extra fat?  How come my body wants me to eat more food, when it's already got a lot of food stored up in the fat?

Asking for a friend,

Well, A.L., I had to read up on this one because I've had that very same question for a long time (imagine that).  Based on what I've read, the answer is: fat don't work like that.

Fat cells very nearly have a mind of their own. They don't work the way other cells do and they don't take direction from many other parts of the body. They will keep getting bigger in spite of other processes going around them which should otherwise direct them not to.
(Diagram from QMP's Plastic Surgery Pulse News)

  • Fat cells in your body are like rich people.  You know how when people start to amass wealth, you would think they'd have that much more they'd be willing to share? (This was the theory behind Reagan's idea of trickle-down economics.) But in fact what happens is people raise their bar for what they consider to be the minimum amount of money they need to live on.  The more they have, the more they feel they need to protect.
  • Fat is like that.  The more fat you have, the more your body is going to give you the prompt to eat more. As one recent New York Times article put it, "We get hungrier because we're getting fatter."
  • For quite a while now, the prevailing wisdom about obesity has been that if you're overweight, you've simply eaten too much.  Too many calories in, not enough burned. That simple.  So all you have to do is un-do that equation.  Eat less and exercise more.
  • Problem is, this is a big fat lie.

This, on the other hand, is not just a joke, it's the truth.
(someecard sourced from All-species fitness)

    • Suppose you've been invited to a really phenomenal dinner. Your friends are going to prepare the best foods you've ever tasted in your life. It is going to be one great big spread of super-deliciousness. They tell you to "Come hungry." What do you do?
    • My answer was that I wouldn't eat much during the day prior to the dinner. Someone in the audience said, "Exercise." You know, "work up an appetite." 
    • Right, Gary said. To make sure you're good and hungry and ready to eat a lot, you eat less and exercise more.
    • So why are we telling obese people that the way to lose weight is to do the very thing we know will trigger us to eat a lot?
  • He does a lot more debunking of the conventional obesity theories and advice. So let me pause a moment here and say, it's time we quit blaming people for being overweight and obese, and started figuring out what we don't understand about how our bodies use food and get to fixing it.
  • Taubes debunks our current thinking about obesity in order to figure out the real answer behind how obesity works. If we know what's causing it, then we can know how to treat it or stop it.
  • The deal is that fat doesn't work the way we think it does.  We've been told that our body stores extra food as fat and then when it doesn't have enough food available, it will burn off the fat.  But it's more complicated than that.
  • Fat cells want to keep their fat.  Fat cells have a membrane that lets stuff in and keeps things from going out.  What is allowed in are fatty acids.  Some fatty acids that you may have heard of are
    • Omega-3
    • Omega-6
    • Prostaglandins
    • Palmitic acid
    • Stearic acid
  • There are all kinds of them.  These are what you get when you eat foods that contain fats. Meat or fish or nuts, for example.
  • The membrane around the fat cell lets the fatty acids in. Then the fat cell combines these with a type of sugar called glycerol to make triglycerides. This is the form in which fats and sugars are stored in your body. More triglycerides in the fat cell, the fat cell gets bigger, and you get fatter.
  • Once the fats & sugars are stored in the form of triglycerides, your fat cell does not want to let that triglyceride out. The holes in the membrane are too small for the triglycerides to pass through, for one thing, so the triglycerides can't get out on their own.

A representation of a triglyceride. Three fatty acids plus glycerol. This makes for a big, complex molecule -- too big to get back out through the fat cell membrane.
(Image from

Another depiction of a triglyceride being made from 3 fatty acids and glycerol, and then being stored in the fat cell of a prairie dog, I think that is.
(Diagram from The KetoDynamic Antidote)

  • In order for the fat and sugar locked in your fat cells to get out, the triglycerides have to be broken down again into their fatty acid and sugar components, and then those can pass back out through the membrane.  
  • But your fat cells do not want the triglycerides to be broken up.  Your fat cells are like, "I worked hard to get these triglycerides. You are not getting these out of me just because you skipped lunch today. Uh-uh. No, sir."
  • When you get hungry, your body doesn't really see the fat stored in your body as available food. Because the stuff it needs is all locked up in those triglycerides. Think of it this way: When you get really hungry, are you going to take the time to dress and roast and baste a turkey? Or are you going to reach into the cupboard and grab the already-made container of pudding and scarf that down in 30 seconds? You are going for the 30-second pudding.

Literally everything in you says EatthepuddingEatthepuddingEatthepudding.
(Photo and recipe from Fine Cooking)

  • Your body is the same way.
  • Your body is like, I'm not going through all the hassle of breaking down those triglycerides. I'm not opening up the fat cell cupboard and mixing up spices and butter and roasting and basting and who knows what else for who knows how long. I need something in my blood, and it's got to be easy for me to get energy out of it because I'm hungry right now!
  • What's the easiest and fastest thing for your body to break down? Sugars. Highly processed carbohydrates. The ready-made pudding.
  • As long as your body can get its bloody little fingers on some simple sugars, it is not even touching what's in those fat cells.
  • So that is why you still get hungry when you're fat.
  • In fact, it's even likely that when you have a lot fat stored up, your body will tell you to eat more often because of it. Because your body has gotten very good at storing sugar, there's even less of it in your bloodstream, so you'll get the hunger prompt more often.
  • How are you supposed to get out of this vicious cycle?  How are you supposed to burn fat when all fat wants to do is store up more of itself?  
  • It seems like the answer ought to be involved in breaking up those triglycerides, which will make the fatty acids and the sugars available again and deplete those fat stores. But how do you break up those big triglycerides?
  • The answer is in a hormone.
  • Various hormones regulate the calorie-burning, food-intaking, fat-storing process. Think about how a child eats a lot and grows bigger. Or how when you hit puberty, if you were a girl, your body started storing fat in places it hadn't before -- breasts and hips -- and that was a good thing. Or if you were a boy, you ate a lot and got taller and also developed muscles. So something is telling your calorie/fat/food-using processes to use food in a certain way when your body was growing versus how it handles food and fat once your body has reached adulthood.
  • The main thing directing the food/fat traffic is hormones. Different hormones turn on certain processes and turn off others. We typically think of hormones as estrogen and testosterone, and it's true, those are two pretty important ones. But another hormone that is very important in the food/fat process is insulin.  
  • Insulin is not the only hormone working inside the fat cells, but it is the big policeman on the block, so to speak.
  • Insulin is the traffic cop directing fatty acids and sugars out of the blood into the fat cell. Insulin is the policeman who is locking the fatty acids to the glycerol and putting them in the triglyceride jail. And when the triglycerides want to bust out of jail, insulin is the guard who tries to keep them from busting out.

This is a very complex diagram that includes things not discussed in this entry, but the main point is to notice all the green boxes which contain the word Insulin and the one red box containing the word Insulin. This shows in how many fat-storing processes insulin is involved.
(Diagram by Keith Frayn, sourced from The Eating Academy)

Insulin. The police officer that does not let the triglycerides out of fat jail.

  • If you can control the insulin, you can control the fat.  More insulin equals more fats and sugars in the triglyceride jail. Less insulin means the triglycerides can bust out and be free.
  • But you do still need insulin, right? Don't people with diabetes have to inject insulin to regulate their blood sugar?
  • Yes. People with Type 1 diabetes don't have insulin being made in their bodies so they have to supply it. People with Type 2 diabetes have had so much insulin pulsing through their blood, their cells are desensitized to it and don't know it's there and so can't control the sugar in the blood. 
  • So, yes, we do need insulin, but as with most things, we don't want too much of it or too little of it.  What's the thing that results in too much insulin? Sugars. Carbohydrates.
  • Here's the process broken down:
    • You get hungry
    • You eat & start digesting food
    • Sugar shows up in the blood
    • Pancreas makes insulin to deal with the sugar
    • Some sugar gets burned as energy right away
    • Insulin ferries leftover sugar & fat to the fat cells
    • Insulin makes sure the sugar & fat (now triglycerides) are not getting out
    • Sugar levels in blood drop
    • You get hungry
    • It all starts over again
  • Of course it's more complex than that, but that's what we need to know for our purposes at the moment.
  • If we could have less insulin locking up the sugar & fat, it would stay in our blood longer and we'd have it available to burn. We don't want that stuff lingering in our blood too long because that's how you get heart attacks and nasty things like that.
  • So maybe we do something else to change the mechanism at the beginning of the process. Maybe we make the body work a little harder to get the nutrients it needs. Instead of letting it scarf down the container of ready-made pudding, maybe we make it reach for a turkey sandwich.

Now this is the kind of turkey sandwich I can get into. Not the slimy, weensy, sliced turkey from a plastic package, but hunks that have been cut off the roasted bird, with a healthy amount of mayonnaise and butter and some cheese too, on whole-grain bread. This one is made with roasted red peppers and pesto and fontina cheese.
(Photo and recipe from inspired2cook)

  • I'm being too metaphorical here. Let me get to the point. The best way to disable this fat-accumulating process is to eat fewer sugars and simple carbohydrates. 
  • When you put more easy-access sugar into your blood, you speed up the whole insulin-making, fat-jailing process. Once the fat is in the jail, your body has practically forgotten it's there, so it asks for more food. If you give it a lot of sugar -- way more than it can burn right away, which is true of those all those sugary processed things like candy bars and soda pop and doughnuts and pudding and children's cereal and most of the things in the mid-section of the grocery store -- if you give it more free sugar than your body can use, it's only going to lock more of it up in the fat jail. It's not going to bust out that stored-up fat, and it is certainly not going to do that if you keep giving it more free sugar.
  • The only way to break the fat-storing cycle is to quit giving your body more free sugar. You have to make it work for its food. Only then will the insulin police let the triglycerides break up and get out of jail. Only then will you start burning the stored-up fat.  Only then will you start losing weight.
  • So the short answer is: want to lose weight? Eat less sugar.

A good way to help yourself eat less sugar is to follow this map of a grocery store layout. Stick to the outer regions. Avoid the pre-made stuff in boxes in the center aisles. Except for the nuts. I'll go into the center aisles for the nuts.
(Diagram from Medicine in Plain Words)

P.S. When I couldn't eat sugar for a while -- and I mean I had no sugar at all. Not just the typical things you'd think of like ice cream or cookies, but also no bread. No ketchup. No tomatoes. It was intense. I ate almost exclusively protein and vegetables. -- I held to the restriction for about 3 months. And I lost 28 pounds. I wasn't even that much overweight to begin with.

When the problem that precipitated this drastic diet went away, I started eating some sugar again. I gained back the weight I'd lost and then some. :(  But I am proof that if you want to lose weight, don't eat the sugar.

P.P.S. I also learned, though another source, that if you're trying to change your behavior, it's much harder to achieve a Don't than it is to achieve a Do. So I'll say that while you're not eating sugar, Do eat proteins. Do eat vegetables. Do eat crunchy, complex things. Do add spice.

Salt & pepper. Two of the best anti-sugar aids ever.

Apple #717: Ginkgo Trees

Yesterday, I was sitting outside a coffee house with my friend, let's call her Kiki Malone, and she noticed that the tree that was shading our table was a ginkgo tree.  I turned and looked at the leaves.  Seeing the distinctive fan shape, I said she was right, it was a ginkgo.

Only the ginkgo tree has leaves with a fan shape.

She said, "It's the oldest living tree in the world."  Then she added, "I think.  A person has to be careful saying things like that around the Apple Lady."

I said it had to get annoying, being friends with someone who often says, "Actually, according to what I learned when I did a Daily Apple on that topic. . . ."  Kiki was very gracious and said it wasn't like that at all.  She also said many positive and appreciative things about this here Daily Apple blog as a whole.

So, as a thank you to Kiki for saying so many nice things about the Daily Apple, here is an entry for you on ginkgo trees.  And let me begin by saying: You were correct.

  • The Ginkgo biloba is the oldest living species of tree in the world.
  •  Fossils of ginkgo trees have been found going as far back as 250 million years plus. 
  • That puts the ginkgo as having been alive in the Triassic period, which suffered a massive extinction event along with enormous volcanic eruptions.  Then the dinosaurs whose names most of us know showed up, and they went through their massive extinction event.
  • Ginkgo trees survived all of that.

  • The following characteristics may be why this tree has been able to survive for so many millennia:
    • No insects like to eat it or damage it
    • It suffers from no serious diseases
    • While it prefers moist, sandy soils, it will grow in just about any type of soil, even alkaline, or acidic, or compacted and not well-drained soils
    • It isn't bothered much by road salt, or air pollution, or occasional high temperatures

This particular ginkgo tree is a 1,400 year-old female. She lives in Jonichiji, Japan.

  • The ginkgo is singular in many other ways as well:
    • It is the only tree with a fan-shaped leaf
    • A single ginkgo tree can live to be 3,000 years old
    • While there are several varieties, it is the only tree in its species
    • While it is the only tree in its species, its classification confounds botanists
  • Some botanists say that the ginkgo is a deciduous conifer -- a type of tree with needles and cones, but which also has leaves that drop in the fall.  True deciduous conifers include several species of larches, bald cypresses, the Chinese swamp cypress, and the Pond Cypress, and the Dawn redwood.  These are also really old species of trees.
  • Some botanists argue that ginkgos are not really conifers, and so therefore are not a decidous conifer.  These botanists say the ginkgo is more closely related to cycads, which is another very old group of plants, of which only some 250 species survive. These live in tropical places and they have leaves that grow out in a radiating circle from the central branch.  They look like palm trees.
  • Still other botanists say the ginkgo is neither a conifer nor a cycad, but completely its own thing.
  • Apparently, botanists have a lot more to figure out when it comes to the ginkgo.
    • The seeds are another really unusual thing about this tree.  The female ginkgo produces a fruit, inside of which is a nut in a shell, and the nut is edible in small amounts.  But I need to break down each of these elements bit by bit.

    The items in these four bowls all come from the fruit. What they call "berries" is the fruit of the female ginkgo. Inside the fruit is the nut in a hard white shell, almost like a pistachio shell. Inside the shell is the nut, which is best roasted. Once that's done, peel the outer layer off the nut to get to the glistening, green nut meat.  But don't eat too many of them, or you'll get a stomach ache.

    What the fruit looks like on the ginkgo branch. These look a little too yellow; might need some more time to ripen.
    (Photo from Kennesaw State University)

    • The fruit looks like a small, yellow plum, but it stinks like crap.  Literally.  Some people say it smells like vomit.  Others say it smells like sulfur.  Still others say it smells like sour milk. Let's just say it reeks bad.
    • It stinks so bad, scientists can't figure out what animal would want to eat that fruit and thus disperse the seed.  They speculate that maybe the animal that used to eat it has since died out and the tree has outlived its disperser.  There are records that badgers used to eat them, but no current evidence of such today.  But somehow the seeds are still getting dispersed.
    • It could be that humans are now the ginkgo's greatest disperser because we now depend on this tree like crazy.  Since it will grow in spite of conditions that threaten other trees, and it has no pests and no diseases that go after it, it's become enormously common, especially in cities. Lots of cities have lined their streets with ginkgo trees.

    • But here again, we run into the stink problem.  People find the stink of the fruit to be so disgusting, they've asked that the ginkgo trees be removed.  In various cities like Easton, PA, and Bloomington, MN, and Lexington, KY, they've done just that.
    • They haven't removed all ginkgos, only the stinky females.

    Catalpa Road  in Lexington, KY lined with ginkgos. Why they didn't call it Ginkgo Road, I don't know.
    (Photo from Panoramio)

    • But there's a small problem: it takes 30 years for a ginkgo to reach its reproductive years. And it is nearly impossible to tell whether a tree is male or female before that time. So the cities that are trying to get rid of the females aren't even sure they've got them all.
    • And then a funny thing happens.  Very occasionally, about 1 out of 100 male ginkgos will mysteriously transform.  It will become female and start producing the stinky fruit.
    • This thing is doggoned determined to reproduce.  I can almost hear those those ginkgo trees giggling at us and saying, "Silly humans. We have lived on this planet for millions of years.  It's going to take a helluva lot more than you puny humans digging up a few of our females to wipe us out."
    • But even that is not all there is to say about the stinky fruits.  They have the same toxin as poison ivy or poison oak.  So if you want to harvest them for the nut inside, you'd better wear rubber gloves.
    • Also, the fruit contains a tannin which will stain your clothes or your shoes. One guy who lives on a street in Pennsylvania lined with ginkgos had to get his car re-painted twice because of the ginkgo stains.
    • Oh, and one more thing.  People say the nut, when roasted, tastes like a cross between edamame, a pine nut, and a potato.  Quite tasty, in other words.  In various countries in Asia, the nut is considered a delicacy and is sprinkled on desserts, or in soups, or served with meats.  Only problem is, the nut carries another kind of toxin which will make you throw up if you eat too much of it.

    I can practically hear all the laughter from the ginkgos up and down this tunnel of them, in a park outside Tokyo.
    (Photo from Maxi's Comments)

    • About the name.
    • The tree is native to China, and then it was brought to Japan. Its name is an Anglicized rendering of the Japanese version of the Chinese name yin-hing, where yin = silver and hing = apricot. 
    • The tree was brought to Europe by a Dutch surgeon in 1727, and then to what is now the US -- Philadelphia, actually -- by William Hamilton in 1784.  A few years later, he suggested to Thomas Jefferson that he might like three of them in his gardens at Monticello. 
    • So the tree is pretty cool.  But I can't talk about the tree without mentioning the supplements.
    • There are all sorts of claims out there about the health benefits of the ginkgo.  In China, they say it's the seeds that have the health benefits. In the US, it's the leaves. Either way, such claims include but are not limited to the enormous list below.

      • One trial that asked people to take ginkgo supplements could not prove anything because they didn't get enough data. This is because the "natural" supplements that people were taking turned out to have less than the required minimum 24% ginkgo extract. The pills didn't have enough ginkgo in them to have an effect. Those "natural supplements" were, in effect, snake oil.
      • If traditional medicine is stumped, do you really think some nutjob with a pile of ginkgo pills is going to know something they don't?  Don't let them suck the money out of you. Smile and nod, and keep on walking. 
      • You know who's getting the last laugh, don't you? The ginkgo trees.  They're like, look at those idiots. Thinking my nuts are doing all kinds of wonderful things for them. All they're doing is dispersing my seeds. Disperse on, humans, disperse on.
