Fruit and Diabetes Risk



New research finds that some fruits reduce diabetes risk, while other fruits have no impact on diabetes risk (and fruit juice increases diabetes risk).


 

FRUIT AND DIABETES RISK

Diabetes has become a significant public health problem in the United States, and around the world, in recent years as obesity rates have continued to climb.  According to the American Diabetes Association, nearly 26 million Americans (8 percent of the population) have diabetes.  Diabetes is a prolific cause of serious illnesses, including heart disease, high blood pressure, stroke, blindness, kidney failure, neuropathy, and limb loss.  Diabetes causes, or contributes to, more than 230,000 deaths in the United States each year.

We all know that fresh fruits and vegetables are an important part of a healthy diet, and have consistently been linked with a reduced risk of cardiovascular disease, diabetes, and cancer (for more details on the links between diet and cancer, see my book, A Cancer Prevention Guide for the Human Race).  But new research suggests that not all forms of fruit are created equal when it comes to maintaining an optimal level of health, including the prevention of diabetes.  This new research study appears in the current issue of the British Medical Journal.

The ongoing Nurses’ Health Study and the Nurses’ Health Study II are huge prospective public health studies that, together, involve more than 150,000 female nurse volunteers, while the prospective Health Professionals Follow-up Study includes more than 36,000 male physicians.  The primary outcome evaluated by this particular public health study was the risk of diabetes associated with fruit intake.

During the long course of this enormous public health study, 12,198 study participants went on to develop diabetes.  After adjusting for other known diabetes risk factors among these more than 185,000 research volunteers, the regular consumption of blueberries, grapes, raisins, apples, and pears was associated with a significant reduction in the risk of developing diabetes.  On the other hand, the consumption of bananas, grapefruit, peaches, plums, apricots, oranges, strawberries, and cantaloupe did not reduce diabetes risk.  At the same time, the consumption of fruit juices, which often contain significant added sugar, was associated with a small but significant increase in diabetes risk.

In summary, the findings of this important public health study indicate that the risk of diabetes appears to be reduced with the consumption of at least 3 servings per week of blueberries, grapes, raisins, apples, and/or pears, while the regular consumption of other common fruits had no apparent impact on diabetes risk.  However, fruit juice consumption was associated with an increase in diabetes risk.

Foods that Decrease and Increase Breast Cancer Risk





 

A new study finds that breast cancer risk is significantly affected by specific foods.


 

 

FOODS THAT DECREASE AND INCREASE BREAST CANCER RISK

As I discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, breast cancer is associated with more modifiable risk factors than any other type of cancer.  Among the many known modifiable risk factors for breast cancer, diet is currently thought to play a relatively minor but still important role.  Now, a newly published research study adds important new information regarding potential links between diet and breast cancer risk.  This new public health study appears in the current issue of the journal Nutrition & Cancer.

In this case-control study, the dietary habits of 3,443 women with breast cancer were compared to those of 3,474 women without breast cancer.  As with previous studies, this new study found that increased vegetable intake decreased breast cancer risk.  Specifically, frequent vegetable intake was associated with a 20 percent overall decrease in breast cancer risk.  Increased intake of the so-called allium vegetables, including onions, garlic, chives, leeks and scallions, appeared to be especially protective against breast cancer in this study.  Although increased fruit intake, overall, did not appear to reduce breast cancer risk, this study did find that certain individual types of fruits appeared to reduce breast cancer risk, including citrus fruits and the so-called rosaceae fruits (apples, pears, peaches, apricots, plums, raspberries and strawberries).  On the other hand, both meat and fish appeared to increase breast cancer risk in this study (as I also discuss in my book).

While questionnaire-based public health studies such as this study provide weaker levels of clinical evidence than prospective, randomized, controlled studies, the findings of this study are largely consistent with similar previous studies, with the exception of the favorable association between specific types of fruit and breast cancer risk.  As an added bonus, most of the foods that were found to decrease breast cancer risk in this public health study are also known to decrease the risk of cardiovascular disease, and other serious illnesses as well.

 

At this time, more than 8 percent of Americans are unemployed.  According to the Bureau of Labor Statistics, however, the unemployment rate for veterans who served on active duty between September 2001 and December 2011 is now more than 12 percent.  A new website, Veterans in Healthcare, seeks to connect veterans with potential employers.  If you are a veteran who works in the healthcare field, or if you are an employer who is looking for physicians, advanced practice professionals, nurses, corpsmen/medics, or other healthcare professionals, then please take a look at Veterans in Healthcare. As a retired veteran of the U.S. Army, I would also like to personally urge you to hire a veteran whenever possible.

Diet and Lifestyle Habits that Decrease Colorectal Cancer Risk

 

Welcome to Weekly Health Update



“A critical weekly review of important new research findings for health-conscious readers”



DIET AND LIFESTYLE HABITS THAT

DECREASE COLORECTAL CANCER RISK

In the United States, approximately 106,000 people will be newly diagnosed with colorectal cancer in 2010, and nearly 50,000 people will die of this disease.  Colorectal cancer remains the third most common cancer (excluding skin cancer) in both men and women, and the third most common cause of cancer death in men and women.  Unlike many other types of cancer, an effective method of screening for colorectal cancer is available, in the form of colonoscopy.  Fortunately, the incidence of this cancer has been gradually declining over the past 20 years, due in great part to the early detection, and removal, of precancerous polyps from the colon and rectum at the time of colonoscopy.

The links between specific lifestyle choices and the risk of developing certain types of cancer forms much of the basis of my new book, A Cancer Prevention Guide for the Human Race.”  The risk of developing colorectal cancer, in particular, has been strongly linked to multiple dietary and other lifestyle factors.  Now, a newly published public health research study from Denmark puts a number on the effectiveness of commonly recommended cancer prevention lifestyle strategies in preventing colorectal cancer.

In this study, which appears in the current issue of the British Medical Journal, 55,487 men and women between the ages of 50 and 64 were prospectively followed for an average of 10 years.  Each of these Diet, Cancer and Health Cohort Study volunteers completed validated surveys regarding their social status, health status, reproductive history, and daily lifestyle habits.  They also completed a food frequency questionnaire that included, among its 193 items, foods known to be associated with colorectal cancer risk (including alcohol).  All study participants also underwent physical examinations that included measurements of their height, weight, and waist circumference.  During the course of this large prospective public health study, 678 participants were newly diagnosed with colorectal cancer.

All study volunteers were assessed in terms of 5 modifiable lifestyle and dietary factors that have repeatedly been linked to a reduction in colorectal cancer risk:  Increased levels of regular physical activity, avoidance of obesity, abstention from tobacco use, minimal intake of alcohol, and the observance of healthy diet habits (including increased fiber intake, decreased dietary fat content, decreased red meat and processed meat consumption, and increased fresh fruit and vegetable intake).  Based upon only these 5 simple colorectal cancer risk factors, the adoption of any one of these 5 colorectal cancer prevention factors was associated with a 13 percent decrease in the risk of developing colorectal cancer.  Among participants who generally observed all 5 lifestyle and dietary prevention factors, the risk of developing colorectal cancer was reduced by 23 percent.  (Of note, while this observed reduction in the risk of colorectal cancer was noted for both colon cancer and rectal cancer, this finding was only statistically significant for cancer of the colon, specifically.)

The results of this large prospectively conducted public health study reaffirm the findings of previous studies, in that the risk of colorectal cancer can be significantly reduced by: Engaging in regular moderate exercise, maintaining a healthy body weight, avoiding tobacco use, minimizing alcohol consumption, and by reducing the intake of red meat and processed meats and fat, while simultaneously increasing the consumption of fresh fruits, fresh vegetables, and whole grain foods.  For a more detailed evidence-based guide to colorectal cancer prevention, order or download your copy of “A Cancer Prevention Guide for the Human Race” now.
