Nutritionists often advocate more fruits and vegetables in the average person’s diet. This is good, albeit incomplete advice. It’s kind of like saying, “Walking is a great form of exercise”. However, walking in a lush park is far more advisable than walking alongside a polluted downtown street. Likewise, increased consumption of just any fruits and vegetables won’t necessarily promote better health. Rather, focusing on low-glycemic, nutrient dense produce is a much better strategy. In practical terms, this means opting for leafy green vegetables instead of potatoes and fruits like kiwis instead of bananas.

In the field of athletics, the term “performance enhancers” has taken on a negative connotation of late. The very mention of it frequently conjures up images of professional athletes “juicing up” on anabolic steroids or synthetic stimulants. Fortunately, in recent years, scientists have uncovered an all natural and much safer alternative that may just improve physical capacity and support cardiovascular health. According to several, peer-reviewed scientific studies, the solution may lie in the humble red beet (Beta vulgaris). Athletes who consume red beet juice, a rich source of naturally occurring antioxidants and nitrates, consistently find benefits in trial performance in a number of activities ranging from bicycling to knee-extensor exercises. The key to the greater stamina reported likely involves the ability of beet juice to improve circulation and increase peripheral tissue oxygenation. What’s more, beet root juice also supports cardiovascular health by reducing blood pressure, irregular blood clotting and, possibly, high triglycerides as well. If there is a down side to drinking red beet juice, it would be its high sugar content. The best way to derive the benefits of beet juice while limiting sugar intake is to supplement with beet root juice extracts or powders. For instance, one the most popular products on the market yields only 5 grams of sugar per concentrated tablespoon of beet juice powder. Finally, if you decide to try beet root juice and you find a distinct reddening when you use the bathroom, don’t worry. This is a well known reaction known as beeturia which affects approximately 14% of the population.

A presentation given at last week’s national meeting of the American Chemical Society made headlines that you may have heard or read about. The claim made was that eating two daily servings of potatoes can lower blood pressure so that the “undeserved bad reputation” of potatoes ought to be reassessed. To that I say, not so fast. There are several key details that are important to note when considering this research and topic: 1) The variety of potatoes used in the current trial (purple potatoes) contain antioxidant pigments, similar to those found in blueberries and red wine, which may reduce blood pressure in and of themselves.  2) Some research suggests that purple potatoes contain higher potassium content than more popular varieties such as white Idaho potatoes. 3) Diets rich in foods containing potassium are capable of lowering hypertension whether they contain potatoes or not. 4) There are many other ways of managing high blood pressure naturally, such as switching from common table salt to any number of salt alternatives which feature essential minerals including magnesium and potassium. Finally, it’s vital to understand that many wholesome foods contain significant quantities of potassium. While bananas and potatoes are most frequently singled out, you should know that a 5 oz fillet of halibut contains approximately 817 mg of potassium, a cup of spinach offers up 838 mg, and an 8 ounce serving of unsweetened yogurt will provide upwards of 600 mg of this often deficient mineral.

The types of products that doctors recommend and manufacturers produce reveal a lot about what they think of us as health care consumers. A prevalent view in both alternative and conventional medicine is that most patients would rather take a so-called “magic bullet” that improves disease markers and/or symptoms rather than address the root cause of  illnesses. The idea is that patients are either too busy or unmotivated to make the dietary and lifestyle changes that are necessary to improve health. Sadly, this widely held notion is often based in reality.

Think of all the pregnancies that take place during the course of a given year. Thankfully, most are relatively free of serious complications. But, about 5% to 8% of all expectant mothers must contend with a condition known as preeclampsia (PE) that threatens both woman and child. Preeclampsia is characterized by a dangerous rise in blood pressure that occurs after the 20th week of pregnancy. Some of the possible symptoms include abdominal pain, nausea, vomiting, blurred vision with the appearance of auras and spots, and swelling in the eyes, face and hands or edema. According to the Preeclampsia Foundation this contributes approximately seven billion dollars a year in US health care spending alone. Worldwide, it may account for as many as 76,000 deaths annually.

There’s nothing like a controversial study to stir up the hornet’s nest that is modern medicine. If you think politics is contentious, just try going up against decades worth of health care policy and theories. That’s exactly what a small group of researchers from the University of Lueven, Belgium and the Journal of the American Medical Association (JAMA) did recently.

Aerobic interval training is by far my favorite form of cardiovascular exercise. It doesn’t matter if I’m on a treadmill, in the gym or walking on the beach. I could be alone or training a group of clients. The bottom line is that if I’m working out, part of my routine is almost certainly composed of walking at variable inclines and speeds. That’s essentially what aerobic interval training (AIT) is. Instead of walking at a constant pace for prolonged periods of time, you simply push yourself to walk faster/harder for shorter intervals followed by less intense intervals in between. Read more »

How many steps do you take on any given day? Most people can’t answer that question with any sense of accuracy unless they use a pedometer. Up until this past Saturday, I know I couldn’t tell you how many times my feet moved forward or backwards per day. No clue. 1,000 steps? Possibly. 4,000 steps? Maybe on a good day. Well, on Saturday the figure was 8,670 steps. To be more specific, that was the total number of steps I took while at the Anaheim Convention Center – the site of this year’s Natural Products Expo West.

Some natural health practices are more difficult for allopathic physicians to accept than others. Take, for instance, herbal extracts. Herbs and prescriptive medications are essentially comprised of one or many chemicals which are responsible for their therapeutic activity. Western medicine is largely based upon this model and quite comfortable with it. So called “energy” therapies such acupuncture, Qi Gong and Reiki are another story. The concept of accessing the power of healing energy simply doesn’t jive with the modern, Western view of medicine.

Some people like to play board games, watch sporting events or knit in their spare time. Me? I like to browse around the Centers for Disease Control and Prevention web site. I sometimes search around there for statistics that help shape the content that ends up here. The other day I found a few interesting facts and figures. I already knew that heart disease is the “leading cause of death for both women and men in the United States”. But I was still stunned by a few other statistics. In 2005, 7.6 million people’s lives ended prematurely due to coronary heart disease. In 2003, almost 40% of adults exhibited two or more of six risk factors for heart disease and stroke (diabetes, high blood pressure, high cholesterol, obesity, physical inactivity and smoking). These figures have probably only gotten worse in the time since they were compiled. This is evidenced by the most recent figure available: “In 2009, heart disease is projected to cost more than $304 billion dollars, including health care services, medications and lost productivity.”

Throughout the ages there’s always been a clash between the norms of past and present generations. We see this is in the way people dress, the music they listen to and even the way they talk. And while there are always groups on both sides of the debate, there are also bystanders who watch on and think: “The more things change, the more they stay the same”. That argument can be logically made in the cultural arena. But I don’t think it holds water when it comes to dietary shifts that have largely taken place over the past few centuries. One of the more pronounced differences in the dietary composition of modern man vs. Stone Age dwellers is a shift in the ratio between sodium and potassium. Read more »

Many years ago I attended a health conference where Dr. Julian Whitaker was giving the key note presentation. He mentioned that he was a strong believer in choosing at least one healthy habit and practicing it every day. In his case, Dr. Whitaker mentioned eating an apple once daily without fail. His reason for doing so was more than the obvious “An apple a day keeps the doctor away” philosophy. The broader point he was trying to make is that engaging in healthy lifestyle choices and/or eating nutritious food works best if we do it religiously. Sometimes having a specific goal in mind can assist us in doing just that. Read more »

Many years ago I worked as a consultant for a number of health food stores. One day a customer remarked to me that his faith in herbs was largely based on the fact that human beings have grown up in the presence of medicinal plants since the beginning of time. He noted that the same could not be said for modern day medications. That’s certainly a valid but, ultimately, incomplete point. A more balanced view might be that humans have historically occupied this planet along side both dangerous and healing botanical neighbors. Read more »

The best way for me to learn is to understand the logic behind a lesson. I need to comprehend not only what is happening, but why. This helps me quite a lot when it comes to the study of natural medicine and nutrition. It’s not enough for someone to tell me that fruits and vegetables protect against cancer or that exercise “does a body good”. I have to be aware of the mechanisms that justify such statements. Very often, these explanations are based on incomplete information and, therefore, need to be modified over time. But even so, at least they provide a reasonable underpinning upon which one can hang a concept. Read more »

You can’t always trust news headlines. I found two recent examples of this on a national cable network and a highly regarded medical site. On the cable news station, one headline touted a story about a woman who was supposedly arrested for “cutting in line” at a discount store. Now that’s an attention grabber! If there’s an actual law against line-cutting, then I was surrounded by hoards of criminals when I recently attended a U2 concert. The truth in this instance is that the person involved also engaged in other inappropriate activities which played a role in her arrest. The second item that caught my eye had to do with a supposed “artificial” sweetener that could lower blood pressure and cholesterol. Which one could it be? Nutrasweet? Splenda? SweetN’ Low? Imagine my surprise when I discovered that oligofructose (OFS) was classified as a synthetic sweetener! That’s news to me, because it is in fact derived from natural sources. Read more »

Technology can be both a blessing and a curse. It’s all a matter of how we decide to use it. The Internet is a good example of this. Some experts warn that sitting in front of a computer for prolonged periods of time can bring about physical and psychological consequences, including obesity and social isolation. But there’s a growing body of science that points to a constructive way to spend time online. Specifically, researchers are finding that overweight individuals can benefit from the educational content and interpersonal support that is readily available to nearly anyone who has an Internet connection.
