Green Tea, Diabetes, and Metabolic Syndrome

Green tea is one of those beverages that just seems perfect for health. Hardly anything has been written bad about it, and more benefits are being discovered and confirmed every day. In particular, a compound in green tea called epigallocatechin-3-gallate (more easily remembered as EGCG) seems to be the main reason for green tea's benefits. A quick perusal through journal article abstracts on EGCG gives nearly 2200 articles - and that's just as of today. (A search for green tea gives over 4000 article references!)

Considering also that diabetes and its precursor, metabolic syndrome, are at epidemic levels in our country today, it is worth looking at EGCG and green tea to see if it has benefits for these people. The results are quite impressive. Just a few articles:

• In September of 2008, the Journal of Medicinal Food released a study concerning EGCG. This study determined that EGCG significantly increased uptake of glucose by muscle cells - over 70% more than the control used in the study. This is great news for diabetics searching for additional ways to help increase control over their blood sugar. It's also great news for athletes who want to ensure their muscles are getting all the fuel they need. (The dose used was not given, unfortunately.)
• A study from February of 2010 showed that when subjects with metabolic syndrome either drank 4 cups of green tea a day or took 2 grams of a green tea extract over 8 weeks, they decreased their weight significantly. The average weight loss was 5.5 pounds with the tea, and just over 4 pounds with the extract. Further, the subjects who drank green tea decreased their LDL levels (the form of cholesterol that increases the risk of cardiovascular disease).
• Another study from September of 2008 demonstrated that when mice were simultaneously fed a high fat diet as well as EGCG gained less weight and had less insulin resistance, lower total blood cholesterol, and liver triglycerides than mice only fed a high fat diet.

The take-home message here: if you are diabetic or have metabolic syndrome, drinking green tea on a regular basis is in your best interest. Four cups a day is excellent, but sometimes not to everyone's taste. In a case like this, a more concentrated extract (called a solid extract) that retains all the properties of the original tea can be more easily consumed; only 1/2 teaspoon of this molasses-like sweet extract is equal to four cups a day.

If you are interested in controlling or preventing diabetes or cardiovascular disease with a comprehensive protocol that may include green tea solid extract - especially if drinking 4 cups of green tea a day seems a bit much - contact your nearest naturopathic doctor. And if I happen to be that nearest naturopathic doctor, of course I'd be happy to see you!

SIGG Water Bottles and Bisphenol A

SIGG is a Swiss company that prides itself on manufacturing environmentally sound water bottles, made from either aluminum or stainless steel. Backpacker magazine has dubbed SIGG “The World’s Toughest Water Bottle” after putting a series of water bottles through a rigorous test, including being pummeled by golf balls shot from a cannon. Aluminum SIGG water bottles have been tested repeatedly to ensure that aluminum does not leach into the water.

SIGG water bottles also have a plastic coating on the inside that prevents them from building up a smell or residue. According to their website, these bottles “exceed FDA requirements and have been thoroughly tested to ensure 0.0% leaching – so they are 100% safe.”

However, on September 7, 2009, the CEO of SIGG, Steve Wasik, publicly apologized about not disclosing that the plastic linings of the popular SIGG stainless steel water bottles contained bisphenol A (BPA). This came as a surprise and a disappointment. SIGG has marketed itself as a great alternative to plastic water bottles. Many consumers who chose SIGG water bottles did so intentionally to avoid further exposure to BPA.

I have already written about the links between BPA and many diseases, including breast cancer, obesity, and diabetes. In my video, I even show a SIGG water bottle that I drank from regularly. It’s a shame that Wasik did not feel that BPA exposure was not a pertinent issue for the consumers who chose SIGG water bottles. He has risked the trust of these consumers and the stability of the company. But to his credit, he has apologized numerous times, and has taken action accordingly.

SIGG began to produce water bottles with a lining that does not contain BPA in August of 2008. The company has also offered a voluntary exchange program for anyone who bought a water bottle prior to August 2008, and who would prefer to have a BPA-free water bottle. This exchange program will be effective until October 31, 2009.

Whether or not the lining does leach contaminants of any sort, it appears that BPA may not be necessary to make an effective lining for water bottles. And this can only be good for the health of consumers.

Ideally, you should drink from water bottles that are BPA-free. Even better, consider avoiding plastic water bottles across the board. Pure stainless steel water bottles (SIGG does sell these) and even glass containers are still the best, healthiest, and most environmentally sound water bottles around. But as an acquaintance pointed out, glass may not be the best choice for children due to its being relatively fragile. So stick with stainless steel for children, and go with either for adults.

Video: Naturopathic Medicine and Chronic Disease

I was pleasantly surprised this morning to open up my Facebook profile and see this video about naturopathic medicine and its role in treating chronic disease. Paul Mittman, ND, is the main speaker and the president of Southwest College of Naturopathic Medicine in Tempe, Arizona. Joining him is Jane Guiltinan, ND, a clinical professor at Bastyr University in Kenmore, Washington, and a past president of the American Association of Naturopathic Physicians. Together, they give a good introduction to naturopathic medicine and what it can contribute to the health epidemics of diabetes, heart disease, obesity, and other related conditions. (These conditions are, unfortunately, rampant in what my old pathology professor referred to as "the overdeveloped world," or the first world countries.)

Watch and enjoy!

Video: Food Sensitivities

Have you been dealing with health issues that just don’t seem to go away? Are you frustrated with taking pharmaceutical drugs that don’t seem to work for you? Would you like to pursue a more natural route to health that honors your body?

What if you were regularly eating a food that was sabotaging your health, and you didn’t realize it? Would you want to know about it? If you are dealing with a chronic health issue, chances are you are also dealing with a food sensitivity, and this may be a cause of your symptoms.

A food sensitivity is basically an immune response to food that your body construes as an invader. The resulting immune reaction can result in a multitude of symptoms. Food sensitivities have been linked to a number of chronic conditions, including irritable bowel syndrome, ulcerative colitis, eczema, chronic fatigue syndrome, recurrent ear infections, attention deficit disorder, celiac disease, depression, migraines, and insomnia.

If you are dealing with any of these conditions and are looking for a better route to health, consider getting tested for food sensitivities, find out what they are, and eliminate them. Also, feel free to check out my website for more information about food sensitivities and naturopathic medicine, and what they can do for you. Thank you for visiting, and be well!

Article commentary: Can These Foods Prevent Diabetes?

I was browsing MSN.com today and found an article by Prevention entitled "Can These Foods Prevent Diabetes?" I always look at these online articles with more than a pinch of skepticism, since some of the information in them can be misleading or downright wrong. Although there is some good information here, this article is not an exception. Let's evaluate the foods Prevention has chosen to be good for diabetes.

1. Coffee. Yes, there is evidence that the caffeine in coffee can increase insulin receptor sensitivity, thus helping to decrease the risk of diabetes. But that's only part of the story. Caffeine also increases the amount of cortisol in the body. Cortisol is the body's main stress hormone, normally secreted during the "fight or flight" response during times of acute stress. But if cortisol is elevated chronically (say, with stressful jobs or when ingesting high amounts of caffeine), it can result in increased abdominal fat and increased blood glucose levels, neither of which are desirable if you're trying to avoid diabetes. Besides, not many people regularly drink coffee black, with no sugar or cream or flavored syrup. That mocha frap or caramel latte will really undermine any efforts to prevent diabetes.
2. Vitamin D. I have no issues with this one. Vitamin D deficiency is endemic in our culture, and has been linked with a variety of chronic diseases, including diabetes. But even the highest food sources of vitamin D are insufficient to bring our body's stores of this hormone back to normal. (And yes, I did say hormone. Strictly speaking, vitamin D is not a vitamin.) Even if you take a daily vitamin D supplement including 5,000 or 10,000 IUs, it's possible that weeks or even months will go by before levels normalize, depending on the extent of the deficiency. The best way to get vitamin D back to normal is to get lots of sunshine exposure to as much skin as possible...much like our ancestors did. Just avoid excessive sun exposure leading to sunburns. In times when you cannot get sun exposure, taking high doses of vitamin D is recommended; 5,000 IU is a good daily dose, and overdosing is highly unlikely. (For more information, check out the Vitamin D Council's website.)
3. Low-fat dairy foods. First off, what in the world is ice cream doing on a list of foods that can prevent diabetes - even if it's low-fat ice cream? Yipes! This sends a terrible message. But on to low-fat dairy foods of all sorts. The study referenced by this article may or may not be accurate; even the study's author admits that people who eat low-fat dairy foods tend to have healthier dietary habits in general. If calcium is the key nutrient here (and evidence thus far doesn't really show that this is the case), then dairy foods like cheese and yogurt are indeed the best sources for calcium. (Incidentally, there is evidence linking dairy intake among young children to type 1 diabetes, an autoimmune condition also known as insulin dependent diabetes.)
4. Cinnamon. In many alternative health circles, cinnamon has been accepted as an effective blood sugar moderator, and it is now easy to find supplements for diabetes that include either powdered cinnamon or cinnamon extract. It may take a long time before cinnamon is accepted by mainstream medicine as an effective treatment for blood sugar control. But in the meantime, it certainly doesn't hurt to include cinnamon in more liberal amounts in your diet, either. Try pork chops with a cinnamon rub, or add cinnamon to your morning oatmeal.
5. General dietary modifications. No problems here. I agree with this article's recommendations: Stop drinking sweetened drinks and substitute tea and water. Switch from refined grains to their unrefined brothers and sisters. Keep protein sources lean, and add more legumes to the diet. Eliminate trans fats. Increase intake of fish and nuts. And despite what the title of this part of the article says ("Eat for your genes"), these modifications are beneficial regardless of what your ancestry may be.
6. Carrots. If the active components here are carotenoids, then why stop at carrots? Taste the rainbow of fruits, vegetables, and spices! The brighter and more vivid the food, the better off you will be. Carotenoids are especially high in yellow/orange foods (like carrots, sweet potatoes, mangoes, and apricots), red/pink foods (tomatoes, salmon, cayenne, and pink grapefruit), and green foods (spinach, kale, and collard greens). Since carotenoids are fat-soluble, it is a good idea to eat them in combination with a healthy oil (such as olive oil) or butter to optimize absorption.
7. Fiber. The link between high fiber intake and decreased blood sugar surges is well-established - particularly for soluble fiber. It can slow the ability of the intestines to absorb sugars that are the result of normal digestion of carbohydrates. Shoot for 40 grams of fiber a day from foods like apples and oatmeal...with cinnamon!
8. Seeds. The key nutrient here is magnesium. And much like vitamin D, magnesium deficiency is rampant in society today. There is actually stronger evidence that magnesium can help prevent diabetes more than chromium (often viewed as the classic nutrient to take when trying to moderate blood glucose). Sunflower seeds may be a good source, as the article points out, but leafy greens, cashews, almonds, most legumes, and even chocolate chips (in moderation!) contain more magnesium.
