High Levels of Insulin Increases Risk for Breast Cancer

Insulin, a  hormone that is produced by the pancreas in the body, helps the body utilize glucose properly. Proper amounts of insulin prevent  hyperglycemia and the complications of diabetes.

However, new research has shown that high amounts of insulin may be harmful. Researchers  have found that women with the highest levels of insulin were 50 percent more likely to develop breast cancer than women who had the lowest insulin levels.
 

Among these women, the influence of insulin on breast cancer risk was quite high," says lead author Marc Gunter, Ph.D. of the Albert Einstein School of Medicine at Yeshiva University, New York City and assistant professor of epidemiology and population health. "Women with the highest insulin levels in their blood were more than two times more likely to develop breast cancer than women with the lowest insulin levels." Moreover, "when we controlled for insulin, the association between obesity and breast cancer became much weaker," Dr. Gunter says. "This means that a large component of that obesity-cancer relationship may be mediated by insulin levels

Intensive Insulin Therapy Reduces Mortality in Seriously Ill Children

 

A new European study suggests that intensive insulin therapy may reduce the risk of death, infection and the length of intensive care stays for seriously ill children,

Abnormally high blood sugar (hyperglycemia) often occurs in critically ill infants and children, and increases their risk of secondary infections and death.

"Targeting of blood glucose concentrations to age-adjusted normal fasting concentrations improved short-term outcome of patients in pediatric intensive care units. The effect on long-term survival, morbidity, and neurocognitive development needs to be investigated,"Dr. Greet Van den Berghe, of University Hospital Gasthuisberg and Catholic University Leuven, Belgium, and colleagues wrote in a journal news release.

Lose Weight to Improve Memory

Do want to remember your wedding anniversary next year? Go on a diet!

The first link between calorie-restricted diets and improved memory in people was seen in a study published Monday in The Proceedings of the National Academy of Sciences. Although the study was small, involving 50 people ages 50 to 72 who ranged from normal weight to overweight, the calorie-restricted group averaged 20 percent improvement in memory performance. The other groups showed no significant change.

Dr. Agnes Flöel, of the University of Münster in Germany, and a researcher in the study, said the memory improvement might be linked to a decrease in insulin and inflammation in the calorie-restricted participants, who lost four to seven pounds.

In my opinion, maybe those who lost weight had better blood flow to the brain and therefore more nourishment and oxygen helped memory.

In either case,  if you want to do well on Jeopardy or remember your kid's birthday or recall all of the words to the Star Spangled Banner, go on a diet and lose weight. You may feel better as well!
