Insulin Resistance in Teens Predictor of High Blood Pressure Heart Disease

Insulin Resistance in Teens Predictor of High Blood Pressure Heart Disease

Researchers in Minnesota say that a low insulin response in the teenage years can be an early predictor of heart disease. They say the insulin resistance is independent of obesity, although obesity may increase the risk of diabetes and insulin resistance.

Dr. Sinaiko says “"The insulin clamp is considered the gold standard to measure insulin resistance, a precursor to type-2 diabetes. Insulin regulates sugars, starches, fats and proteins in the body. When cells become resistant to the effects of insulin, insulin levels increase to regulate metabolism." Sinaiko is lead author of the study and professor of pediatrics at the University of Minnesota Medical School in Minneapolis.

More Fat People Than Starving in the World - Obesity is the New Health Crisis and Causes Health Problems

More Fat People Than Starving in the World - Obesity is the New Health Crisis and Causes Health Problems

There are now more obese people in the world than starving people, and an international conference in Australia is calling for incentives to address this urgent problem. This may be a sign of the times, since it is much easier to acquire food today than it has ever been. Early humans spent most of their days working to provide a meal.

The shift from starvation to obesity happened quickly, according to Barry Popkin, a nutrition professor at the University of North Carolina. He believes the shift has occurred because there was a global dietary shift away from cereals and grains to animal products and vegetable oils.

One Cup of Coffee Quadruples Risk of Heart Attack in Light Drinkers – People with Heart Disease More Susceptible Too

One Cup of Coffee Quadruples Risk of Heart Attack in Light Drinkers – People with Heart Disease More Susceptible Too

A cup of coffee may cause a heart attack in some people within an hour of drinking it, according to a study reported in the journal Epidemiology (“Transient Exposure to Coffee as a Trigger of a First Nonfatal Myocardial Infarction,” (Volume 17, Issue 5, September 2006.) The risk was highest among people with light or occasional coffee intake, and those with a sedentary lifestyle or other risk factors for coronary heart disease.

Just One Meal High in Saturated Fats Clogs Arteries – Polyunsaturated Fats Help

Researchers in Australia say that just one meal high in saturated fat may affect the body’s ability to protect itself against artery-clogging plaques. On the other hand, by eating a meal high in polyunsaturated fats can increase the anti-inflammatory properties of HDL, helping to protect the inner lining of the arteries (endothelium).

Dr. Stephen J. Nicholls says “The take-home, public-health message is this: It's further evidence to support the need to aggressively reduce the amount of saturated fat consumed in the diet. This study helps to explain the mechanisms by which saturated fat supports the formation of plaques in the arterial wall, and we know these plaques are the major cause of heart attack and stroke." Nicholls is one of the researchers and now a cardiologist at Cleveland Clinic in Ohio.

Toxic Food Environment Causes Obesity - Low Fiber High Sugar Foods More Common Today Makes You Gain Weight

Toxic Food Environment Causes Obesity - Low Fiber High Sugar Foods More Common Today Makes You Gain Weight

A scientist from the University of California San Francisco (UCSF) says that kids are overweight because their diets consist of high-calorie and low fiber foods. This typical Western diet promotes a hormonal imbalance that encourages children to overeat.

Another recent study found that babies are heavier now than they were 20 years ago. The manufacturing changes may be the reason. Dr. Robert Lustig believes the way food is manufactured has created a “toxic environment” that dooms children to be overweight. Lustig is professor of clinical pediatrics at UCSF Children's Hospital.
According to Lustig, "It will take acknowledgement of the concepts of biological susceptibility and societal accountability and de-emphasis of the concept of personal responsibility to make a difference in the lives of children."
