Osteoporosis: Can Vitamin K Help Save the Day?


By Justin Wiggins
Postmenopausal women may have a little less reason to worry about osteoporosis, a degenerative disorder characterized by low bone mass, which leads to an increase of fractures, especially in the hips, spine, and wrist. A new study suggests that vitamin K may have bone-boosting potential.
Calcium plus vitamin D-enriched dairy enhances bone mineral density. Once Vitamin K1 or K2 is added to the formulation, there are increases in levels of osteocalcin, a vitamin K-dependent protein that is essential for the body to utilize calcium in bone tissue.  If the body is not getting enough vitamin K, osteocalcin levels can drop, becoming ineffective.
Vitamin K is available in two forms; vitamin K1 and vitamin K2. Vitamin K1 can be found in green leafy vegetables like lettuce, broccoli and spinach. Vitamin K2 can be found in animal meat and fermented food products like cheese and yogurt.
Researchers from Harokopio University in Greece conducted a study that investigated the effects of dairy enriched providing 800 mg per day of calcium and 10 micrograms per day of vitamin D3, with or without the addition of 100 micrograms per day of either K1 or K2.
After 12 months of the study, researchers found that only the women who consumed the vitamin K-enriched products had significant increases in bone mineral density in their vertebrae and the lower back (lumbar spine).
Over 75 million people suffer from osteoporosis in the US, Europe and Japan, and women are four times more likely to develop it than men. For this reason, it is important that studies like this occur in order to help provide clues for reducing the risk of osteoporosis. Steps taken now with diet or supplements are always steps in the right direction, that can lead towards lowering that number.

Study Finds Location Linked to Vitamin D Deficiency

Did you get your daily dose of sunshine today?  If not, you may need a vitamin D supplement!Author: Sean Wells
Along with other recent news related to the health benefits of Vitamin D–sometimes called “The Sunshine Vitamin”–is the question of whether or not extra Vitamin D is required by certain individuals. With some historical evidence to support it, a widely-held belief is that people living out in the country tend to be in better health overall than city-dwellers, and that one of the underlying causes is the combination of enjoyable fresh air, exercise and, of course, extra sunlight.

Times do change, however, and in recent years residents of rural areas have shown “significant health disparities”, including certain types of cancer and an increase in heart disease that is now comparable to those who live in cities; diagnosis displayed a tendency to occur in later stages, with a corresponding increase in medical expense for treatment. A primary cause of this negative health trend is believed to be Vitamin D deficiency.

To investigate, a recent study compiled the medical records of some 9,396 veterans from 2003 to 2009 across various regions of the southeastern United States. Two factors were cross-referenced: Vitamin D levels, and area of residence. Three categories were established as well–large metropolitan, urban and rural.

Somewhat surprisingly, the population residing in urban, mid-size cities showed the least likelihood of deficiency, while large metropolitan area populations were 49 percent more likely to be deficient in Vitamin D. Those living in areas classified as rural, however, were shown to be 20 percent more likely to be Vitamin D deficient as compared to the first group as well.

As part of their conclusion, the authors stated: “Pending further clinical trials on vitamin D, it appears prudent to use vitamin D to improve health outcomes and potentially reduce costs, since benefits far outweigh the risks of modest vitamin D replacement.”

As the saying goes, an ounce of prevention is worth a pound of cure. Along with the ongoing research that increasingly indicates benefits of Vitamin D, and an RDA for this nutrient that has also been on the rise in recent years, it would seem worthwhile for most of us to consider testing, and perhaps Vitamin D supplementation–wherever we live.

Maximize Mood with Passionflower and L-theanine

Author: Sean Wells For better or for worse, these days a certain amount of anxiety from time to time is normal, and certain situations such as first dates or job interviews are expected to generate an above-average level of stress. If, however, you are finding that you’re consistently feeling worried about everyday matters, this may be something worth just a little more (stress-free) contemplation.

The general recommendation for those who aren’t suffering from truly overwhelming, disabling stress and anxiety is that a more natural approach be taken. Two substances which are produced naturally and show promise for anxiety relief are the botanical known as passionflower and the amino acid L-theanine.

Passionflower had a long tradition as a native remedy before analysis indentified it as a natural source of Monoamine oxidase inhibitors (MAOIs), anti-stress compounds which work as “cushions” to protect against sudden variations in mood. Passionflower appears to buffer the effect of stress hormones, and in studies has demonstrated benefits for people diagnosed with Generalized Anxiety Disorder (GAD).

L-theanine is typically found in green tea, and has the comparably rare ability to cross the blood-brain barrier; as such, it is capable of exerting positive influence on levels of both GABA and dopamine—two neurotransmitters responsible for mood regulation. In Japan, where green tea consumption is especially popular, L-theanine has been linked with stress-relief.

An estimated 40 million Americans suffer from some form of regular anxiety, and although prescription drugs exist which can help with calming down, there is some question as to the viability of their long-term use. These pharmaceuticals can be accompanied by side effects like dizziness, drowsiness and forgetfulness—along with tendencies for certain of them to be habit-forming.

For stress relief, there are certainly healthier habits that can be cultivated. Regular exercise, healthy eating, limited caffeine and relaxation techniques such as deep breathing all come highly recommended, and practices like yoga combine some of these elements to great effect. A little attention to the nutritional extras mentioned above might be just right to round things out and preserve balance.

Nip Allergies in the Bud

Try these Ayurvedic tips to help you get a handle on your allergies.
By Niika Quistgard of yogajournal.com
Increase Circulation.  Try a dry-brush massage before your morning shower and a vigorous round of Sun Salutations before breakfast.
Drink Hot Water.  Fill a thermos with hot water as your day begins. Carry this with you and sip an ounce or two of hot water every 30 minutes all day, between meals, to loosen and cleanse ama.
Lighten up.  Steer clear of heavy foods, such as dairy, wheat, and rich, cold dishes (yes, that means ice cream). Rely mainly on freshly cooked, prana-filled fruits and vegetables, which are nourishing yet easy to digest.
Eat Lunch.  Enjoy the most substantial meal of the day at noon when digestion is strongest; keep dinner light.
Avoid Toxins.  Reduce your exposure to chemical preservatives, household cleaners, and pesticides to avoid introducing excess toxins into your body.
Take a Remedy.  Mix ¼ teaspoon of trikatu (an Ayurvedic formula of three dried peppers) with a teaspoon of honey. In the morning, eat this mixture, followed by sips of hot water.
Clear the Nose.  Use a neti pot daily to rinse irritants from your nasal passages. Fill the neti pot with warm water. Stir in a pinch of salt until completely dissolved. With your left hand, bring the spout into your left nostril, lean over a sink, and tilt your head to the right, tipping the pot up gently to start the flow. Continue for up to 30 seconds, breathing through your mouth. Repeat on the other nostril.


Express Your Self


Nothing fuels the creative process like a spacious mind and an observant heart.
By Shannon Sexton of yogajournal.com
Inspiration strikes. Suddenly, you find yourself writing an essay, redesigning your garden, presenting a plan to your boss, conjuring up a new career. Seemingly from out of nowhere, a spark of creativity is ignited and you have a vision, plus the optimism and enthusiasm, and even a sense of urgency, to bring it into being. If you stop and pay attention as the idea takes shape, you'll notice that your mind in that moment feels relaxed and spacious.
Observe those moments over time and you'll recognize a pattern: The creative impulse seems to be activated as soon as there's a little breathing space in your mind. Sometimes it feels as if the idea, or the solution to some vexing problem, was waiting patiently all along, just out of reach, until your mind stopped churning in its breathless quest for an answer. It's astounding how quickly your creativity unleashes itself in the fertile ground of a peaceful mind.
"Creativity is actually the living, breathing essence of your Self," says Sianna Sherman, an Anusara Yoga instructor who teaches internationally. To tap into it, you simply need to make space for it.
Too often, Sherman says, the vast creative aspect of the Self gets hidden or pushed aside in the hustle and stress of everyday life. You can grow disconnected from it and even forget that this wellspring of imaginative possibilities and inspired solutions to your troubles resides right inside you.
Kundalini Yoga teacher Hari Kirin Khalsa, a painter who wrote Art & Yoga, says: "When you're under stress, you're contracted and fearful. Everything is black and white. You're not intuitive; you're instinctive. You can't think outside the box." But by practicing asana, pranayama, meditation, or devotional chanting, she says, you can shift out of that stressful state and connect with your imaginative, spacious Self. "Yoga opens up the flow of creativity, the unfurling of the creator within."
Whether you're an artist, an engineer, or a parent heading to an important meeting when you learn your sick child needs to be picked up at school, you rely on creativity to meet everyday challenges. And you thrive on its ability to fill your life with beauty, purpose, and meaning. So even if you've never really thought of yourself as a "creative type," why not encourage your most imaginative Self to emerge?

Diet For A Healthy Planet


To be eco-friendly and heart healthy, try eating vegetarian.
By Katharine Mieszkowski of yogajournal.com
Kat Saks grew up in Montana, where meat was always on the table. In fact, she had never considered not eating meat. But when she began yoga teacher training at Laughing Lotus Yoga Center in Manhattan and her instructor mentioned that vegetarianism was one way to practice ahimsa, the yogic principle of nonharming, she decided to try it for the duration of the program."I wasn't confident I would make it through the four months,"she admits.
Saks's journey to vegetarianism was not without setbacks. In the first few weeks, she struggled with cravings, even "slipping" once and eating a piece of chicken. But as the months went by, she felt transformed. "I noticed a significant shift in my mood and emotions, and a general lightness of being on my mat—I felt more fluidity of movement, and everything was just a little bit easier," she says.
Almost two years later, Saks, 27, is fully committed to a vegetarian lifestyle, in which spinach, beans, and grains like quinoa have become the new staples in her diet. "I fell in love with it after a while," Saks says. "I was skeptical at first, but practice is believing."
Many students find that yoga and vegetarianism go well together; ahimsa, a central tenet of classical yoga, is often used as an argument against eating meat—and, some argue, against the consumption of any animal products. And it's not just yogis who are giving up meat. About 3 percent of Americans don't eat meat or fish (including the less than 1 percent who are vegan, eschewing eggs, dairy, and honey as well), according to a 2009 poll conducted by Harris Interactive for the nonprofit Vegetarian Resource Group. Many more are striving to eat less meat. Another poll, conducted in 2008, found that a full 10 percent of Americans have considered going vegetarian.
Be The Change
From a health standpoint, there is good reason to consider plant-based eating. Vegetarian diets are associated with a number of health advantages, including lower cholesterol and blood pressure levels, compared with meat-based diets. Vegetarians are less prone to cancer, hypertension, and type 2 diabetes, according to the American Dietetic Association. On average, they also have a lower body mass index.
Even in the city of Chicago, famous for its Polish sausage and Italian beef sandwiches, government officials extol the health benefits of eating less meat. For the past three years, Terry Mason, MD, Chicago's health commissioner, has given up meat for the month of January, encouraging residents to do the same. Last year, Mason, a urologist who suffers from high cholesterol and had a coronary stent implanted in 2005, went even further and gave up meat for seven months—and is now working toward giving it up for good. "I'm going to focus on eating a healthy and delicious variety of fresh fruits and vegetables," he says.
As awareness grows about the personal health benefits of eating less meat, so too do concerns about the ethical and environmental implications of a meat-based diet. The average American consumes an astonishing 31 land animals per year, and at least that many crabs, lobsters, and fish, according to the Humane Society of the United States.
"Most farm animals are raised in factory farms, industrialized large-scale facilities where they suffer immensely," says Paul Shapiro, a spokesman for the organization. "To the extent that we reduce the consumption of animals, we reduce an enormous amount of suffering."
Many yoga practitioners are taking that to heart. "I can't even imagine going back to eating meat," says Diana Rein, 32, who lives in Los Angeles and has been a vegetarian for more than two years. After a few months of practicing vinyasa yoga daily and listening to her teachers talk about ahimsa, meat became unappetizing. "Something clicked," she says. "It was strange, but I haven't wanted it since."
Some say that this kind of shift in awareness about the connection between what\'d5s on your plate and its impact on the world around you is common when you commit to a regular yoga practice. "The goal of yoga is to dissolve the state of exclusive, individual reality into one that's inclusive, or one consciousness,"says Los Angeles yoga teacher and former Vedic monk Steve Ross. "From this nondual way of looking at things, everything is a part of you. When you realize this, you don't want to harm any being or any form."
This feeling of connectedness often extends to a desire to care for the environment, and there's growing evidence that what's on the other end of your fork has far-reaching implications for the health of the planet. Raising animals for slaughter contributes to land erosion and water pollution. And a seminal 2006 United Nations report found that, globally, livestock and dairy farming produce more greenhouse gas emissions than transportation. Two engineering professors at Carnegie Mellon University calculated that a person choosing to eat a plant-based diet rather than meat just one day per week would reduce greenhouse gas emissions by the same amount as driving 1,000 fewer miles per year. Going entirely vegan would be equivalent to driving 8,000 fewer miles per year.
Balanced Eating
Whether you want to live longer, strive to eat more in accordance with the principles of ahimsa, or hope to lighten your environmental footprint, there are plenty of reasons to give up or eat less meat. But you also need to make sure that you're getting enough of the key nutrients such as protein, iron, calcium, and B-12 vitamins.
"Deciding to be a vegetarian doesn't mean that you're going to be healthy," says Keri Gans, a spokeswoman for the American Dietetic Association and a registered dietitian in Manhattan. "I've had young women coming in with their hair falling out because they're not eating a well-balanced vegetarian diet."
Laura Valle, 37, an American who lives in Selfkant-Höngen, Germany, and practices Ashtanga Yoga, dabbled with vegetarianism at different points in her life for both health and ethical reasons. But even after adopting the diet full-time in 2007, she found herself living on the vegetables and starches she prepared, but not adding anything extra to accommodate her new diet. Soon, she was constantly hungry and craving salt and junk food.
"I wasn't making balanced meals," she says. She studied up on nutrition for vegetarians through books, DVDs, and podcasts and began adding whole grains, beans, and things like tempeh, a soy protein, to her diet. "I realized I had to have a better range of foods to eat," she says. "And then I just started to feel great."
Around this time, a bout of adult acne led her to also give up dairy (which she says cleared the condition), and soon thereafter, she cast eggs out of her diet to become vegan. Her husband followed suit a few months later.
In general, a healthful vegetarian diet will include plenty of fruits and vegetables, whole grains, and lean protein such as beans and tofu as well as sources of heart-healthy fats, such as avocados, nuts, and olive oil, Gans says. Whatever you do, don't replace the meat in your diet with heaping bowls of mac and cheese or slices of pizza. Common pitfalls for new vegetarians include eating too much saturated fat in the form of full-fat cheese or filling up on low-fiber carbohydrates.
If you include processed foods in your diet (such as veggie burgers or frozen organic dinners), be sure to check the sodium content, which can be just as high as in the meat versions.
Take It Slow
If you haven't yet made the switch to a plant-based diet but are curious, you might want to consider trying it for a month, like Chicago's Dr. Mason—or even one day a week. Meatless Monday, for example, a popular initiative backed by the Johns Hopkins Bloomberg School of Public Health, works to inspire Americans to do just that for the sake of their health and that of the planet.
The good news is that in recent years it's gotten a lot easier to make the change to a plant-based diet. "Five years ago, if you wanted soymilk, you had to go to Whole Foods. Now, you've got Ralph's, Albertson's, and Safeway asking: "What kind?" says Nancy Berkoff, a registered dietitian in Long Beach, California.
Whatever the motivation, new and aspiring vegetarians should be gentle with themselves as they strive to give up meat. "Very few people become vegetarians overnight. It all depends on what they ate to begin with," says Berkoff. "Usually, it's a gradual process." When Diana Rein, who is training to become a yoga teacher, first went vegetarian, she found she gained weight because she was eating a lot of stuff she hadn't previously indulged in—including sweets and foods made with refined flours. "I just thought, 'This is vegetarian,'" she says. Over time, however, her tastes have changed. "It's hard at first to clean up your diet, but once you do, you really do stop craving the other stuff that you thought you wanted."
Getting What You Need
According to nutritionists, it's easy to get almost everything you need from a plant-based diet. Here's how some common nutrients measure up.
Protein
Protein provides the amino acids essential for the growth and repair of tissue. The average American woman needs about 60 grams (g) per day. Men need about 70. One cup of cooked beans has about 15 g; a cup of barley, 11 g; a cup of cottage cheese has 15 g; and a cup of soybeans, about 22 g. If all your protein comes from plant-based sources, make sure you eat a variety of these foods every day, to ensure that you get the correct balance of amino acids your body requires.
Iron
A deficiency of this mineral limits the delivery of oxygen to the cells, leading to fatigue and brain fog as well as to decreased immunity. Men need 8 milligrams (mg) per day, while women need 18 mg, and pregnant women need 27 mg. There are plenty of plant-based iron-rich options: Nuts, tofu, dark leafy greens, and lentils are good sources. (Pairing these with foods high in vitamin C, such as tomatoes, peppers, and citrus fruit, will increase iron absorption.) And many breakfast cereals are fortified with it.
Vitamin B-12
B-12 is vital for the maintenance of nerve and red blood cells, and it's used to make DNA. Both men and women should get 2.4 micrograms daily. While it's abundant in fish, meat, poultry, eggs, and dairy products, it's not present in plant-based foods. However, some breakfast cereals, like Kashi's Heart to Heart, are fortified with B-12. Silk and organic Wildwood soymilks both offer 50 percent of the recommended daily value per serving. Some rice drinks and veggie burgers are fortified with it as well. And Red Star Vegetarian Support Formula nutritional yeast supplies the recommended daily intake in about two teaspoonfuls.
Calcium
Most vegetarians get a similar amount of calcium in their diet as meat eaters do, but vegans (who don't eat dairy products) tend to get less, so they might consider taking a supplement to make up the difference. The recommended daily intake of calcium for most men and women is 1,000 mg. A cup of plain low-fat yogurt has roughly 448 mg; a cup of nonfat milk has 316 mg. One cup of steamed collard greens has 266 mg, and a cup of calcium-fortified orange juice has 300 mg. Look for calcium-fortified soymilk and tofu, too. As for supplements, be aware that, unless specified, many multi-vitamins provide only a small amount of calcium.
Omega-3 fatty acids
Omega-3 fatty acids are important for cardiovascular, eye, and brain health. But if you don't eat fish, your diet may be low in two important ones, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
The World Health Organization recommends 0.3 to 0.5 grams daily of both for men and women. Another important omega-3, alpha-linolenic acid, or ALA, is abundant in plant sources such as flaxseed, walnuts, soy, and canola oil. Aim for 1 to 2 grams per day. (The body can manufacture EPA and DHA from vegetarian ALA sources, although you'll need a lot more.)
Algae supplements provide some DHA, and so do eggs from hens fed an omega-3-rich diet. Udo's Oil DHA 3-6-9 Blend provides a balance of vegetarian omega-3 and omega-6 oils, with DHA from farmed red-brown algae. The good news is that while vegetarians who don't eat fish may miss out on the heart-healthy benefits of EPA, their cardiovascular health is on average superior to that of meat eaters.

 

Supplements: Dietician-Approved

By Justin Wiggins
Supplements, by definition, are something that completes or enhances something else when added to it. Dietary supplements are no different; they are supplementing a healthy diet, which some might believe is already nutritious enough. So how do dieticians feel about the use of supplements, especially those who specialize in dietary recommendations?
According to a new survey from the Council for Responsible Nutrition, dietitians are regularly using dietary supplements and the majority of them have recommended supplements to their clients at some time.
300 dieticians participated in the survey and 74% reported that they regularly used dietary supplements in their own nutritional plans.  The top two reasons for their supplement use were bone health and overall health, respectively. When asked if they had ever recommended dietary supplements to their clients, 97% of the dieticians said they had done so.
Of the supplements used by dieticians themselves, the most popular was a multivitamin, followed by calcium, omega-3/fish oil, vitamin D, vitamin C, probiotics, B vitamins, and fiber supplements.
The survey was conducted to be a part of the “Life…supplemented” campaign by HCP Impact Studies. According to Judy Blatman, who is the Senior Vice President of communications for the CRN, “Our industry needs a program like this—a forward-thinking communications platform that educates consumers about dietary supplements as one component of healthy living.”
This survey shows strong support by dieticians in favor of dietary supplements. Almost three-quarters of the respondents stated that they themselves used supplements regularly and almost all of them have recommended them to their clients. These days, living a “supplemented”  life is more than just a smart option–it’s starting to look like doctors orders!
