Green Tea and Metabolic Syndrome

Wednesday, July 28th, 2010

Because metabolic syndrome is something I tend to see on a weekly basis, it’s always good to see new information on what can help to control and reverse this condition. The latest research points out the benefits of green tea in treating metabolic syndrome. It’s also well known that green tea contains weight-loss promoting properties, among many other beneficial compounds. 

Here is a summary of the research findings:

Reference: “Green tea minimally affects biomarkers of inflammation in obese subjects with metabolic syndrome,” Basu A, Lyons TJ, et al, Nutrition, 2010 Jun 1; [Epub ahead of print]. (Address: Nutritional Sciences, Oklahoma State University, Stillwater, Oklahoma, USA).
Summary: In a randomized, controlled study involving 35 obese subjects with metabolic syndrome, results indicate that green tea intake may exert cardioprotective benefits. The subjects were randomized to receive green tea (4 cups/d), green tea extract (2 capsules and 4 cups water/d), or no treatment (4 cups water/d) for 8 weeks. At intervention end, green tea (drink and capsule) intake was associated with significant reduction of plasma serum amyloid alpha, compared with control. Thus, the authors of this study conclude, “green tea significantly reduced plasma serum amyloid alpha, an independent cardiovascular disease risk factor, in obese subjects with metabolic syndrome.”

Weight Gain and Fatty Acids-Born Into Obesity?

Wednesday, July 21st, 2010

For years, the naturopathic profession has emphasized the importance of balancing the ratio between omega 3 and omega 6 intake. The standard American diet is overloaded with omega 6 fatty acids, while being deficient in omega 3, which can lead to a chronic inflammatory state, increasing the risk of cancer and other serious diseases. Now, a new study in the Journal of Lipid Research has found that a high omega 6:omega 3 ratio may not only lead to insulin resistance in individuals, but may actually predispose their offspring to a life-long struggle with obesity.

In addition to high consumption of fast foods and refined carbohydrates, the high omega 6:omega 3 ratio in the American diet is largely due to the shift from grass-fed to grain-fed livestock. For meat eaters, this means seeking out sources of locally raised or grass-fed livestock, along with incorporating more wild game (bison, venison) into the diet. In general, a diet that is well-balanced with fruits, vegetables, fish, and healthy oils should insure a healthy balance of omega fats. Supplementation with fish oil and ground flax seeds is also recommended, to further bolster your omega 3 intake. 

Dementia and Vitamin E

Wednesday, July 14th, 2010

The July 2010 edition of Archives of Neurology contains a study that demonstrates an inverse relationship between vitamin E intake and dementia risk, including Alzheimer’s. Participants in the study were followed for roughly a decade, and those who had the highest dietary intake of Vitamin E were shown to have the lowest incidence of dementia. Overall, higher vitamin E intake was linked to a 25% reduction in dementia risk. 

Food sources of vitamin E include wheat germ, spinach, broccoli, almonds, and hazelnuts. Although this study didn’t take vitamin E supplementation into consideration, you still may want to consider supplementing with 200 IU of natural, mixed-tocopherol on a daily basis for optimal health benefits. 

Heart Disease and Anxiety

Wednesday, July 7th, 2010

The July issue of the Archives of General Psychiatry contains a study that demonstrates a 74% increased risk for adverse cardiovascular events (stroke, heart attack, and sudden death) in patients with general anxiety disorder (GAD). While it’s often been speculated that many patients with coronary heart disease (CHD) are also anxious, this study is the first of it’s kind to prove that there is indeed a definitive link between anxiety and heart disease. 

This study is further proof that the mind-body connection cannot be ignored. If your stress level is consistently high, don’t wait until you begin to experience symptoms before taking the necessary steps to address your anxiety. Naturopathic medicine can offer a number of therapies, including botanical, nutritional, acupuncture, and biofeedback, to help you manage stress more effectively. The Heart Math Institute (www.heartmath.org) offers tips and products that help you “retrain” your stress response, making you less prone to the adverse effects of anxiety. MoodGym (http://moodgym.anu.edu.au/welcome) is another online resource that is recommended for this purpose. 

Who’s Bad? (Not Fats)

Thursday, July 1st, 2010

There continues to be a false assumption in the medical community that increased fat consumption leads to heart disease and other long-term problems. I often find it difficult to reprogram people, after they’ve been brainwashed for so many years to avoid fats, and eat only low-fat foods. This topic warrants much more detail than what I can cover in one blog post, but evidence continues to mount that refutes the low-fat concept. For example, a recent study in the American Journal of Clinical Nutrition (2010 May 12) demonstrates that people with higher levels of omega-3s and fats derived from olive oil and nuts had an inverse correlation with coronary artery disease. This further supports the advantages of following a Mediterranean Diet, and disregarding the “Food Pyramid” recommended by the USDA.
