Part 1: The real story about sugar, does it turn into body fat, how does it affect health?

Dear friends,

In view of alarming increase of diabetic patient at the age of 40, the article below might help us to think about ourselves.

In explaining this subject to many people over a period of several years, I found the most useful metaphor to be that of an automobile engine. Let's take a Toyota Corolla, one of the most popular cars on the street today. The Toyota Corolla has an engine that's designed to burn a certain type of fuel. That fuel, gasoline, has a certain flash point and a given output of power per gallon of gasoline. There are other fuels that power other types of vehicles -- for example, jets run on a high-octane petroleum product that has far more energy per gallon than automobile gasoline. Diesel fuel, on the other hand, burns more slowly.

So you have different types of fuels for different vehicles. Most people understand the idea that if you took your Toyota Corolla, drove it down to the airport, and filled it up on jet fuel, you wouldn't get a faster Toyota Corolla. Instead, you would get a critically damaged Toyota Corolla engine, because the fuel would burn too hot, too fast, and it would overpower the design of the engine. In fact, you probably wouldn't drive more than 10 miles before the engine burned up, and you would have to overhaul the entire engine in order to drive your car again.

This is sort of what goes on when it comes to the human digestive system and sugars. The human digestive system was designed to consume foods that are readily available in the natural surrounding environment. These foods can be compared to certain types of fuels because each food releases energy at a given rate during digestion (primarily based on fiber and fructose content).

As an example, let's take a look at an apple. It contains fiber, vitamins and minerals, and lots of carbohydrates. The carbohydrates are the fuel. But the carbohydrates are bound up in the fiber of the apple so that it takes your body a fair amount of time and effort to release those carbohydrates and convert them into fuel. So you could call the apple a medium-burning carbohydrate, or in medical terms, it has a lower glycemic index than straight sugar.

But if you take straight sugar, that is, refined white sugar, which is something that does not occur naturally in the environment, and you put that in your mouth, then your body converts that into blood sugar very rapidly. It's like pouring jet fuel down your throat. This is the same as filling up your Toyota gas tank with jet fuel and trying to drive away. When you eat sugar you consume soft drinks -- which are even worse because they are liquid sugar -- you are trying to run your metabolic engine on jet fuel, and the human metabolic engine was not designed to run on jet fuel.

So what happens? When you first consume any sort of refined sugars or refined carbohydrates (like white flour), the digestion process begins immediately -- in fact, it begins even before you swallow the foods. There are digestive enzymes in your saliva that go to work on these sugars and start converting them into blood sugar, even before they hit your stomach. Once they're in your stomach, they are mixed with acidic digestive juices and physically churned through stomach muscle contractions so that it creates a liquid paste. This liquid, sugary paste is then very easily absorbed through the intestinal walls, causing a rapid spike in blood sugar levels.

So your blood sugar, which might have been around 80 or 90 before you drank the soft drink or ate that candy bar, now suddenly starts spiking up to 150 or 200, or perhaps even higher. This creates an emergency situation in your body. High blood sugar is very dangerous for human beings. If it is allowed to continue, it will cause symptoms that are more classically known as diabetic neuropathy, which means the nerves that feed various limbs in your body (feet, mostly) start to die. Diabetics who maintain high blood sugar over a long period of time often have to have their feet amputated because the nerves in their feet are wasting away.

Assalamu'alaikum warahmatulLah

Aku tak pasti samada orang lain selalu visit kita punya blog ni, atau visit tapi sekadar menjengok, atau dah tak ada ummph lagi selepas berlalunya Grand Gathering kita dulu?!

Tapi bagi aku, aku tetap singgah walaupun tak sekerap dulu sebab menghargai usaha saudara kita, Ashraf menghidupkan blog ni.

Setiap kali aku jumpa kawan lama, 'X-Manjung' aku tetap promote kat depa ttg blog kita ni. Baru-baru ni aku jumpa Yus Asma (DPA), memang selalu jumpa pun sebab dia jadi Ass. Registrar kat UUM, so aku promote laa pasal blog ni di samping bertukar-tukar crita pasal kawan-kawan lama.

Sebelum tu, aku ada kunjung-jumpa sorang memba/yop/lope yg dah tak aktif lagi memblog. Katanya, dia senyap pasal (1) reunion dah berlalu, tunggu 2/3 tahun lagi baru dia nak menyampuk (2) X-7 dah tak menulis, tak dak org nak 'disampukkan' (3) topik-topik yg ke udara (boleh dak guna 'dimayakan') terlalu berat...dah tak sesuai utk disampuk-merapu... Begitu katanya...

Cadangan aku, apa kata kalau tiap kali kita singgah di blog ni, kita tinggalkan sebaris dua ayat supaya kawan-kawan yg lain tahu yg kita masih 'hidup'.... tak selalu pun tak pa, asalkan ada tinggalan. Tak leh karang, hantaq jaa text copy yg selalu kita trima dari email thread yg diforwardkan ke email kita. Kadang-kadang ada nasehah.., kadang-kadang ada info baru... tak kurang jugak arus panduan ttg makanan, ttg kesihatan.

Sbg cth, Ashraf kita dah postkan topic 'sugar' ni... Bnyk yg boleh diambil iktibar dan boleh jugak disampukkan....

Dulu ada Amir cdgkan teh tarik session, tak tau jadik ke tak... Ni dah dekat Ramadhan ni, mungkin boleh ada siri berbuka puasa pulak kot?

Kalau tak jadi tak pa, sebab dengaq kata kita nak makan kenduri Zai tak lama lagi... Dah lama tak berkonvoi pi kenduri kawan ni. Baru-baru ni, ada laa konvoi tapi konvoi menziarah jenazah.
(dia akan tetap ada dalam memori kita... Pak Are-G)
