I've been writing about obesity and something called hyper-insulinemia for about as long as I can remember. For those of you who don't know, many people nowadays have something called metabolic syndrome, which is a cluster of symptoms including obesity, high blood pressure, elevated insulin levels, and high cholesterol. The main component of all of these is something called hyper-insulinemia (which is also called insulin resistance). What I just wrote is pretty much accepted as fact nowadays. What is still up for debate is a) whether insulin resistance is the cause or the effect of obesity and ...

It's widely recognized nowadays that many people have a condition known as insulin resistance. Internally, their cells have become desensitized to insulin, which ultimately forces the body to create more of it in order to meet the cellular demands on the body (insulin is required to move glucose into the cells for usage). Unfortunately though, high insulin levels lead to heart disease, type II diabetes, obesity (or a difficulty in losing weight), high blood pressure, and are potentially implicated in several cancers, including breast. This metabolic condition is known in the literature as "metabolic ...

I do the odd post from time to time on health issues and current research I think is interesting. About a year ago I posted an article discussing how caffeine seems to have a negative influence on the body's insulin signaling, which ultimately affects blood sugar levels in the blood. What this ultimately means is that caffeine might be a major contributing factor in the obesity epidemic, since high insulin levels in the blood promote the storage of fat and make it difficult to burn it. Here's a recent 2008 study that investigated the effects of caffeinated coffee and decaffeinated coffee on the ...

I picked up a book the other day that I've been meaning to read for a few months now. It is a book by a scientific journalist named Gary Taubes entitled Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health (Vintage) (although after reading it, I think a more appropriate title might be something like "The People's History Of Diet And Nutrition.") For those of you who follow nutritional research, you may remember Gary from a controversial article he wrote in 2002 in the New York Times called 'What If It's Been A Big Fat Lie?" In that article, ...

Part of the reason I wrote the last article on insulin resistance is so I could continue to talk about that subject without continually explaining what it is I was talking about. Sometime around the year 2003, there was a pretty seminal study performed that had an undesirable, although extremely fascinating outcome. The researchers at the time were trying to guage the body's insulin response to various foods. When they came to apple pie though, they were in for a surprise: Just half a teaspoon of cinnamon a day significantly reduces blood sugar levels in diabetics, a new study has found. The ...

Sylvain sent me this link today that basically concluded that one or more cans of diet soda can lead to health risks such as the metabolic syndrome "We found that one or more sodas per day increases your risk of new-onset metabolic syndrome by about 45 per cent, and it did not seem to matter if it was regular or diet," Dr. Ramachandran Vasan, senior investigator for the Framingham Heart Study, said Monday from Boston. .. The study included nearly 9,000 observations of middle-aged men and women over four years at three different times. The study looked at how many 355-millilitre cans ...

I was coming into work this morning, and I read this on the front page of the Vancouver Sun. This is pretty big news in the medical community. Apparently some researchers at UofT have found a way to reverse diabetes in Type 1 diabetic mice. This is exciting because it was always thought that type I diabetic people lost the ability to produce insulin because their own immune system completely destroyed the beta cells in the pancreas. However, the beta cells in these mice became active again once they had an injection. Here's the original article. Also surprising is that this approach also seems ...
