Researchers May Have Found Cause of Type 2 Diabetes 181

ozmanjusri writes "Scientists at Sydney's Garvan Institute have identified an enzyme called PKCepsilon as the active agent that blocks the production of insulin in diabetics. Insulin injections and implants try to control levels but do not address the reasons why insulin production is failing. This discovery may allow pharmaceutical companies to develop a drug to block the enzyme, allowing cells in the pancreas to function normally, though the team's leader, Trevor Biden, says 'What we've identified is a target that we can now latch onto to get therapy, but the journey from target to tablet of course is a long one ... It's probably going to take another 10 years at least to get something that's effective in humans.'"

    Your body constantly works to maintain equilibrium of all functions. The is a reason Type 2 diabetes almost exclusively occurs in gluttonous people, and is virtually unknown in countries where food is comparatively expensive and scarce. This is because after years of consistent overeating, your body begins to believe that elevated levels of blood sugar is "normal" and there is no need to produce more insulin. This is no different than people who drugs or alcohol. Using drugs or alcohol long term results in your body assuming that is "normal" and it stops producing similar chemicals, which drugs mimic. When you stop using drugs or alcohol, withdrawal symptoms result until your body readjusts.

    This particular enzyme is the way your body controls this behavior in regards to insulin, it is not the "cause".

    I guess "being overweight and unhealthy" wasn't scientific enough.

    On the one hand, I always like to see things cured. On the other hand, my fear of type II diabetes is one of those things that gets my ass out of bed in the morning, makes me walk to lunch, makes me have an apple instead of a twinky.

    It like if they came up with a wonder pill that fixed all the bad cardiovascular problems you get from eating all the wrong stuff, a diet pill that keeps you from gaining any weight, and a cure for type II diabetes...I'm just not sure that would really be good for anyone. You should ahve to have some consequences.

    I understand that there are those who get Type II through no fault of their own, and this makes me happy for them...But they're the minority, and I don't have as much sympathy for the rest.

    people eat like shit and don't exercise. That's it. Pretty simple huh? Fiances father got diagnose with type 2 diabetes. Effecting him pretty badly for a year. Decides to eat healthy, drop weight, and exercise. Guess what happened? He is healthy now, no issues. You read tons of studies saying the same thing.

    But that isn't profitable to companies....

    My brother is athletic and in good shape, he just ignored the signs of it (inherited type 2) and ended up needing an emergency heart bypass in his 40s. He sure watches his blood sugar now.

    "It isn't just a genetic predisposition. There is a proven link between obesity and type 2. "
    Did you think that you have the link backwards?
    Yes people that get type 2 do often have trouble with weight. Ever think that the genetic predisposition might just cause that problem with it also contributes to that tendency to be over weight? BTW it isn't just being over weight. It is a specific body type that get is. People that tend to put on weight all over don't seem to get type 2. People that put weight on around the middle do!
    Yes it is a genetic predispositions. With a very good diet and exercise if you have that disposition you may put it off until old age or maybe never. But there are many genetic issues that can helped by lifestyle changes and not just diabetes. That is why it is a predisposition. Depending on the gene load it may be treatable with just diet and exersice or it may not be.
    But to blame it on gulttiony is ignorant and cruel.

    Unhealthy lifestyle choices are only really frowned on because they result in poor health. Isn't it perverse to perpetuate that moralistic norm if the poor health consequence goes away? (There are some cases where poor health isn't the only negative consequence, but I'm not referring to those.)

    I'd say that, far more than people realize, health problems can be nailed down to nutritional issues. I don't mean "too much fat" or that sort of thing. People suffer weird symptoms from specific vitamin deficiencies and the like.

    For instance, I know one person who suffered from "hypothyroidism" for a long time and had to take T4 supplements. It turned out that her real problem was an iodine deficiency, that itself was likely caused by being on the birth control pill. Taking high doses of an iodine supplement cleared up the problem very quickly, and her thyroid began functioning properly again.

    I know another patient who was inexplicably ill for many years. After an IgG panel blood test, it was determined that she had a food alergy to casein, the principal protein in milk and other dairy derivatives. This isn't the sort of IgE alergy that causes itching or anaphalaxis, but the IgG kind that takes days to set in, and the symptoms are less severe and can be flu-like. Part of the reason she never considered cutting out dairy was that she is not, in fact, lactose intolerant, so lactase ensyme didn't help. Eliminating dairy entirely solved her problem.

    Just like the preceding case, I have an IgG reaction to soy protein. Imagine trying to avoid soy in the U.S. Soybean oil is the default "vegetable oil," soya lecithin is used as an emusifier in lots of foods, and soy protein isolate (not considered to be a food by the FDA) is added to lots of things that want to report having high protein content. Oh, and don't forget the estrogen analogues found in soy. Anyhow, challenging as it was, eliminating soy products resulted in a huge improvement to my energy level. (I suffer from chronic fatigue syndrome, and my nutritionist believes that it was caused by the soy alergy compromising my immune system.)

    I know lots of people who have suffered from prolonged illness that was completely blown off by MDs that was then remedied very quickly by a nutritionist. And it frustrates me to no end how ignorant MDs are about nutritional effects and that they never refer people to nutritionists!

    Ok, so what's my point? That in a lot of cases, I would not be surprised of there was some kind of food that people are sensitive to or which is eaten to excess that has compromised part of their metabolism. Taking insulin shots was a bandaid for diabetics. Taking something to inhibit PKCepsilon production is a BETTER bandaid, but it's still a bandaid. Someone's got to figure out the root cause.

    Oh, did you know that a significant number of autism cases, when caught early enough, show remarkable improvement when wheat and dairy are removed from their diets? Many neurologists will tell you otherwise, but that's because they just don't study nutrition in school. The nutritionists know otherwise.

    Oh, and BTW, I'm not against MDs. I just know their limitations. Got a broken bone, lyme disease, or a structural organ failure? Better go to an MD. But many of the little things that affect people's health are not in the "take this pill" or "let me operate" categories but rather in the "don't eat this" and "eat this instead" categories. The effect of environment and intake has a HUGE impact on the human body!
