The Fabulous Four

Dr. Dana King and his team of researchers at the Medical University of South Carolina have completed a very inspirational study.  Dr. King and his team set out to find if middle-aged adults could reap the rewards of habits like eating vegetables and walking 30 minutes a day.

The researchers reported in June 2007 that middle-aged adults age 45 to 64 who began eating five or more fruits and vegetables every day, exercising for at least 2 1/2 hours a week, keeping weight down and not smoking decreased their risk of heart disease by 35 percent and risk of death by 40 percent in the four years after they started.- The adopters of a healthy lifestyle basically caught up. Within four years, their mortality rate and rate of heart attacks matched the people who had been doing these behaviors all along, said Dr. Dana King at the Medical University of South Carolina, who led the research.  Dr. King added “even if you have not had a healthy lifestyle previously, it’s not too late to adopt those healthy lifestyle habits and gain almost immediate benefits”�

The four key habits are eating five or more servings of fruits and vegetables everyday, exercising for 2 ½ hours per week, not smoking and maintaining a healthy weight.  The study participants who adopted all four healthy habits enjoyed a sharp decline in heart disease risk and in death from any cause.

It took all four - having just three of the healthy habits yielded no heart benefits and a more modest decrease in overall risk of death.

Still, said Dr. Nichola Davis at the Albert Einstein College of Medicine, “these benefits are on a continuum. The more of the healthy habits that you can adapt, the better....These are modest changes that they’re talking about.”

Antioxidants

If you think back to your days in high school or college chemistry, you probably remember the topic of molecules. A molecule has a nucleus at the center and then a certain number of electrons that orbit around the nucleus. Normally, the molecules that make up your body are balanced; they have an even number of electrons. A free radical is a molecule that has lost one of its electrons leaving it with an odd number of electrons.

These unbalanced free radical molecules attempt to stabilize themselves by “stealing” an electron from another healthy molecule. The cells your body where this process is occurring can become injured. The cell may malfunction causing disease or even become malignant causing cancer. It is also widely believed that free radicals are one of the main causes of the aging process.

The body produces free radicals through normal metabolic pathways such as extracting energy from the food we eat. Exposure to the toxins in junk food or polluted air, for example, can also be sources of free radical production. In short, we are exposed to potential sources of free radical production every day of our lives.

Antioxidants are nutritional compounds in whole foods that have extra electrons. When an antioxidant comes in contact with a free radical - the antioxidant “donates” an electron to the free radical. This way, the free radical doesn’t have to

“steal” an electron from another healthy molecule and the damage normally caused by the free radical can be avoided. The antioxidant nutrients themselves do not become free radicals when they “donate” an electron because they are stable in either form.

The human body is capable of producing antioxidants naturally, but under conditions of a poor diet, toxicity, physical stress or emotional stress this antioxidant production can be severely impaired. Do you know someone who eats a poor diet, has high levels of toxicity and is stressed out much of the time? This is why they may appear older than they actually are.

Eating a healthy whole food diet and drinking plenty of water are two of the best ways to protect your body from the damage of free radicals. Fruits and vegetables provide an excellent source of natural antioxidants to help your body stabilize the free radicals and ward off the damage that they cause.

The Power of Cinnamon

Just half a teaspoon of cinnamon a day significantly reduces blood sugar levels in diabetics, a new study has found. The effect, which can be produced even by soaking a cinnamon stick your tea, could also benefit millions of non-diabetics who have blood sugar problem but are unaware of it.

The discovery was initially made by accident, by Richard Anderson at the US Department of Agriculture's Human Nutrition Research Center in Beltsville, Maryland. "We were looking at the effects of common foods on blood sugar; one was the American favorite, apple pie, which is usually spiced with cinnamon. We expected it to be bad. But it helped," he says.

The active ingredient in cinnamon turned out to be a water-soluble polyphenol compound called MHCP. In test tube experiments, MHCP mimics insulin, activates its receptor, and works synergistically with insulin in cells.

To see if it would work in people, Alam Khan, who was a postdoctoral fellow in Anderson's lab, organized a study in Pakistan. Volunteers with Type 2 diabetes were given one, three or six grams of cinnamon powder a day, in capsules after meals.

All responded within weeks, with blood sugar levels that were on average 20 per cent lower than a control group. Some even achieved normal blood sugar levels. Tellingly, blood sugar started creeping up again after the diabetics stopped taking cinnamon.

In the volunteers, the Cinnamon also lowered blood levels of fats and "bad" cholesterol, which are also partly controlled by insulin. And in test tube experiments it neutralized free radicals, damaging chemicals which are elevated in diabetics.

Cinnamon's essential oils also qualify it as an "anti-microbial" food, and cinnamon has been studied for its ability to help stop the growth of bacteria as well as fungi, including the commonly problematic yeast Candida.

In a study, published in the August 2003 issue of the International Journal of Food Microbiology, the addition of just a few drops of cinnamon essential oil to approximately 3 ounces of carrot broth, which was then refrigerated, inhibited the growth of the food borne pathogenic Bacillus cereus for at least 60 days. When the broth was refrigerated without the addition of cinnamon oil, the pathogenic B. cereus flourished despite the cold temperature. In addition, researchers noted that the addition of cinnamon not only acted as an effective preservative but improved the flavor of the broth.

Research led by Dr. P. Zoladz and presented April 24, 2004, at the annual meeting of the Association for Chemoreception Sciences, in Sarasota, FL, found that chewing cinnamon flavored gum or just smelling cinnamon enhanced study participants' cognitive processing. Specifically, cinnamon improved participants' scores on attention related processes, virtual recognition memory, working memory, and visual-motor speed while working on a computer-based program.

(Hint: simmer a few cinnamon sticks in water while your kids are doing their homework - this will also serve as wonderful yet non-toxic air freshener for your home)

In addition to the active components in its essential oils and its nutrient composition, cinnamon has also been valued in energy-based medical systems, such as Traditional Chinese Medicine, for its warming qualities. In these traditions, cinnamon has been used to provide relief when faced with the onset of a cold or flu, especially when mixed in a tea with some fresh ginger.

Walnuts May Prevent Breast Cancer

April 21, 2009

DENVER - Walnut consumption may provide the body with essential omega-3 fatty acids, antioxidants and phytosterols that reduce the risk of breast cancer, according to a study presented at the American Association for Cancer Research 100th Annual Meeting 2009.

Elaine Hardman, Ph.D., associate professor of medicine at Marshall University School of Medicine, said that while her study was done with laboratory animals rather than humans, people should heed the recommendation to eat more walnuts.

"Walnuts are better than cookies, french fries or potato chips when you need a snack," said Hardman. "We know that a healthy diet overall prevents all manner of chronic diseases."

Hardman and colleagues studied mice that were fed a diet that they estimated was the human equivalent of two ounces of walnuts per day. A separate group of mice were fed a control diet.

Standard testing showed that walnut consumption significantly decreased breast tumor incidence, the number of glands with a tumor and tumor size.

"These laboratory mice typically have 100 percent tumor incidence at five months; walnut consumption delayed those tumors by at least three weeks," said Hardman.

Molecular analysis showed that increased consumption of omega-3 fatty acids contributed to the decline in tumor incidence, but other parts of the walnut contributed as well.

"With dietary interventions you see multiple mechanisms when working with the whole food," said Hardman. "It is clear that walnuts contribute to a healthy diet that can reduce breast cancer."
