Preventing Diabetes

Because diabetes is a condition where blood sugar is too high, many people mistakenly think that eating too much sugar is the primary cause of diabetes. While sugar is a contributing factor, there are many other habits that can increase your risk of developing this disease:

• Obesity (BMI of 30 or more) and overweight (BMI of 25-30) both increase the risk of diabetes, and even modest weight loss (9 pounds in three years) in someone with elevated blood sugar levels can cut the risk in half. Regular exercise can lower the risk, as well.

• Consuming simple carbs such as potatoes and white bread increases the risk while whole grain consumption lowers it.

• Trans fats increase the risk of diabetes while those who eat the most polyunsaturated fats have a lower risk.

• Eating one serving of red meat a day increases diabetes risk by 22% over those who eat red meat once a week. Processed meats such as hot dogs, bacon, and lunch meats increase the risk even more.

For more information on dietary fats, obesity, healthy eating, and exercise, scan the archives of this blog and stay tuned. These topics will continue to appear in the months ahead.

Blood Sugar and Diabetes

If you watch television, you’ve probably seen ads related to blood sugar testing. The incidence of diabetes is rising, right along with Americans’ waistlines. Diabetes occurs when the body cannot regulate blood sugars. Uncontrolled diabetes increases your risk for eye problems including blindness, high blood pressure, heart disease, stroke, kidney failure, and nerve damage. Data from 2007 indicate that 23.6 million children and adults in the United States—7.8% of the population—have diabetes, and the number is growing is each year (www.diabetes.org).

What is considered a healthy blood sugar (glucose) level? Glucose levels are measured through a blood test where the sample is drawn by a medical professional from a vein or by a finger stick. There are a variety of tests and the kind of test done determines what a healthy level is, as shown below:

• Fasting (at least 8 hrs since eating): normal range is 70-99 mg; beginning of diabetic range is 126 mg

• Two hours after beginning last meal: normal range is 70-145 mg; beginning of diabetic range is 200 mg

• Random: normal range is 70-125 mg; beginning of diabetic range is 200 mg*

* Other symptoms must be present such as increased thirst and frequent urination (especially at night), unexplained increase in appetite, unexplained weight loss, fatigue, erection problems, blurred vision, and tingling or numbness in the hands or feet

There are several risk factors for diabetes. We’ll look at those next time. In the meantime, make sure you speak to your doctor about how often you need to get your blood sugar level checked. (Unless otherwise noted, the source I used for this article was www.mebmd.com.)

Hormones Increase Breast Cancer Risk

Did you read recently in the Arizona Republic that women who take estrogen and progestin after menopause not only increase their risk for breast cancer, but also face even a somewhat increased chance of dying from the disease? How does this differ from what we already knew? How great is the risk? It can be confusing to sort it all out, so here are the facts:

• Eight years ago a federally funded study called the Women’s Health Initiative revealed that the risks of heart disease and breast cancer outweighed the benefits of taking estrogen and progestin for relief from menopause symptoms.

• Although at the time researchers thought the risk of death from breast cancer was not any greater, the use of the hormones dropped almost 65% from 2002 to 2009. Still, some 40 million women were taking the hormone combination.

• As a result of the diminished hormone use, breast-cancer diagnoses started to drop.

• Last year researchers concluded that women who took the hormones were 70% more likely to die of lung cancer. Lung cancer and breast cancer are the two leading causes of cancer death in women.

• Now that researchers have 11 years of data from the study, they have determined that the tumors that result from the hormone combination are just as likely to be the more difficult to treat type of tumors, not the smaller, less-threatening ones they had thought eight years ago. This means the risk of dying from breast cancer is slightly higher.

• Still, this newly identified risk of death from breast cancer as a result of hormone use is low.

• Researchers recommend that women who take the hormone combination do so at the lowest effective dose for the shortest period of time. There continues to be debate about whether five years is too long to be on the hormones.

• The use of estrogen alone, which women who have had hysterectomies take, does not carry the risks reported here.

There are many other risk factors for breast cancer, such as smoking, a sedentary lifestyle, a diet high in saturated fat, and genetics. Be sure to discuss your risks carefully with your physician so you can make the most informed choice about your health.

Safe Sex Applies to All Age Groups

In 2007 when I was researching and writing my book, Worth Waiting For: Sane Sex for Singles, I was amazed to learn that unsafe still happens in every age group – a lot. How is this possible? While the safe sex message is not as prominent as it was fifteen years ago, it is still being promoted. The target age group, however, is young—under age thirty. Yet, although the message is aimed at this audience more consistently than it is at those over forty, an alarming number of young adults still have unsafe sex. Of the twenty-five to forty-four-year-olds surveyed, 39 percent did not use a condom the last time they had sex and likewise for 20 percent of the eighteen- to twenty-four-year-olds. Sadly almost half of the new STD infections are among adolescent girls (www.alternet.org/sex/62429)!

How about those over 45? Is it possible they have not heard of safe sex? I think it’s unlikely, but consider a study conducted by the New York Department of Health and Mental Hygiene in May 2008. Of single people with at least two sexual partners, some 44 percent of those over age forty-five reported not using condoms the last time they had sex. A University of Chicago survey of single women ages fifty-eight to ninety-three revealed that nearly 60 percent said they hadn’t used a condom the last time they had sex. It’s not surprising then that, in less than a decade, STD rates have more than doubled among people ages forty-five and older. From 1996 to 2003, the total cases of chlamydia, genital herpes, gonorrhea, syphilis, and genital warts among people over forty-five increased by 127 percent (.http://health.usnews.com/usnews/health/articles/070805/13senior.htm).

But these STDs aren’t the only concern for this age group. According to the Centers for Disease Control and Prevention, the majority of HIV carriers by 2015 will be over age fifty, and about 15 percent of new infections occur in this age group. It’s alarming to consider that an Ohio University study found that about 27 percent of HIV-infected men and 35 percent of HIV-infected women over fifty sometimes have sex without using condoms (http://www.physorg.com/news96724718.html).

Although HIV/AIDS is not the automatic death sentence it once was, it not curable. Safe sex is not an option. It is a requirement every time for anyone who cherishes their health and well being.
