Roast some Chestnuts for a Healthy Holiday

December 16, 2009 by wellcoaching

Thanks to the popular Christmas tune about roasting them “on an open fire with Jack Frost nipping at your nose” , chestnuts are most associated with the winter holiday season. In reality, however, they are a healthy, delicious treat that can be enjoyed year-round.

Sometimes referred to as the “grain that grows on a tree”, chestnuts are lower in fat (and protein) and higher in carbohydrates than other nuts. An ounce of chestnuts contains only .3g  fat, 1.2g protein (the lowest of all nuts) and 14.4 g carbohydrates. There are only 68 calories in 1 oz of chestnuts (about 3 nuts) compared with 204 calories in an ounce of macadamia nuts or 161 calories in an ounce of peanuts. Chestnuts also contain a decent amount of Vitamin C and folate and like all nuts they have zero cholesterol. They are also low on the glycemic index and thus are an excellent choice for diabetics.

Originating from southern Europe, chestnuts can be eaten boiled or roasted, used as a fresh vegetable, mashed into a puree or ground into flour. They are excellent in soups, porridges, casseroles, stuffings, stews – even pastries.

Available fresh (in autumn), dried or canned, chestnuts should be slit before cooking otherwise they can explode with the heat. Dried chestnuts should be soaked for at least 1-2 hours and boiled for 45-60 minutes. Fresh nuts need boiling for 40 minutes before being peeled. Chestnuts are perishable and so should be refrigerated. Fresh chestnuts will keep up to two months if refrigerated in a ziplock bag.

Be Well,

The Latest on Antioxidants – Part II

December 9, 2009 by wellcoaching

In my previous post I addressed the recent divergent news reports on the benefits and possible harm associated with consuming antioxidants. I also discussed the difference between taking supplemental antioxidants and obtaining them through food.

One study that has received a lot of attention lately found that taking supplementary antioxidants Vitamins C and E may negate the benefits of exercise, namely the increase in insulin sensitivity, a measure of the risk of heart disease and metabolic syndrome. Subjects who exercised and were given antioxidants showed less insulin sensitivity than exercising subjects who did not take the supplements. Exercise naturally increases insulin sensitivity, a positive side effect, but exercise also triggers the release of free radicals which stress the body and cause, among other things, muscle soreness. Researchers theorized that the body produces its own natural  antioxidants after exercise to mop up the free radicals produce and that taking supplementary antioxidants suppresses this natural process. It’s as though the body has a natural check and balance system, where it shuts down internal production when it receives external support.

This is another reason why I encourage my nutrition clients to obtain as many nutrients as possible from foods and why the concept of nutrient density is so important. The nutrient density of a food is basically how many nutrients a food provides per calorie. Vegetables have by far the highest nutrient density of all foods.

If you want to know specific antioxidant levels of the foods you eat, check out this helpful antioxidant database. It lists the  Oxygen Radical Absorbance Capacity (ORAC) unit -or antioxidant capacity- of different foods. It is believed that foods higher on the ORAC scale will more effectively neutralize free radicals. Some of the chart-toppers may surprise and please you. Spices such as cloves, cinnamon, turmeric and parsley rank among the highest in available antioxidants – all the more reason to use them when seasoning your food. You’ll be happy to know that dark chocolate is also high on the list. Note: this list is unrelated to nutrient density  - it doesn’t take into account calorie content of a food.

Be Well,

The Latest on Antioxidants- Part I

December 5, 2009 by wellcoaching

Lately a lot of confusing and seemingly contradictory  reports on antioxidants have surfaced. One study suggests taking antioxidant supplements may reduce and even reverse the benefits of exercise. Another study touts antioxidants for their ability to prevent the H1N1 virus and seasonal flu. So what’s to believe?

First of all, there appears to be a difference between taking antioxidant supplements and obtaining them through food. Because vitamins, minerals and other phytonutrients work synergistically, it’s best to get them from food where they’re naturally available in the appropriate proportions for optimal absorption and assimilation. This is one of the reasons I recommend taking a multivitamin, rather than supplementing with high levels of single nutrients. In certain cases, taking high levels of  some micronutrients can lead to malabsorption of other micronutrients. Many people, for example, pop multiple zinc lozenges during the cold and flu season to prevent illness. But high levels of zinc can interfere with copper absorption. On the other hand, even multivitamins have not been shown to prevent illness or disease or prolong life, which is why you should obtain most of your nutrients from  food, not pills.

There’s now a growing field called nutritional immunology where researchers are studying the power of nutrition in healing injuries and preventing illness. Says Anuraj Shankar, researcher at Harvard’s School of Public Health, ” If you don’t have an adequate intake of vitamins and minerals you won’t be able to produce the number of immune cells you need, and the immune cells you do produce may be compromised.”  So, eating a nutrient-dense diet is an important defense in warding off both acute illness and chronic diseases.  

This is probably the first time in history where its possible to be both obese AND  malnourished – to have access to an overabundance of calories containing a low-level of nutrients. Research also suggests that diets high in saturated fat and sugars appear to suppress the immune system. This is perhaps one of the reasons obesity is now a risk factor for cancer.

The key nutrients that appear to boost the immune system are: vitamin D, available  through sun exposure and in cold water fish such as salmon, eggs and fortified dairy products; vitamin C, plentiful in fruits and vegetables, including strawberries, kiwi, tomatoes, red bell peppers and, of course, citrus; vitamin A, found in liver, spinach, pumpkin and sweet potatoes; vitamin B-6, found in bananas, potatoes and beans; selenium, whose sources include Brazil nuts, seafood and turkey; and zinc, found in shellfish, pork and beef.

In my next post I’ll look at whether taking antioxidants bolsters or blunts the benefits of exercise. Until then…

Be Well,

Wearing a Cellphone May Decrease Bone Density

November 30, 2009 by wellcoaching

While research on the risks of long-term cellphone usage have focused on possible links to cancer, a recent Turkish study has found that wearing a cellphone clipped to the hip may decrease bone density of the hip. This is of particular concern to men as women are more likely carry their cellphones in their handbag rather than attaching them on their bodies.  

Last year an Israeli study found an increased risk of cancer of the salivary glands of  heavy cellphone users on the side of the face they typically place the phone when speaking. This was particularly true of subjects who living in rural areas. Due to fewer antennas, cell phones in rural areas need to emit more radiation to communicate effectively.  The researchers found that the heavier their cellphone usage, the more likely subjects were to develop parotid (the main salivary gland) tumors.

With both of these studies, the message seems to be that having a cellphone connected to the body for long periods of time is potentially harmful. The subjects in the Turkish study, for example, wore their cellphone on their hip an average of 15 hours a day. The authors believe young people to be at the greatest risk because of typically heavy daily usage and potentially life-long usage.

If there is indeed a risk, it is likely on the rise as the use of the cellphones continues to increase with the popularity of the smartphone, which doubles as a mini-computer and a phone. Furthermore, many  people like me no longer keep a land line phone. I found no need for one as I no longer have a fax machine and receive my wireless connection through my cable modem. I do, however, make an effort to avoid long cellphone conversations and when I do speak on the phone I use headphones instead of a bluetooth.

Smart phones are here to stay, but perhaps we need to be a bit more intelligent when using them or eventually we may be exchanging our health for their convenience.

Keys to Good Posture: Part II

November 25, 2009 by wellcoaching

In my last post I discussed the importance of good posture and some of the physiological causes and signs of poor posture. Now I’d like to address ways to realign your spine into a healthy, “neutral” posture.

To align your spine, first do the following:

Stand with your back against a wall in your normal, relaxed posture.  Bring your shoulders up by your ears and then drop them down, feeling your shoulder blades sliding down the wall.  Slip your hand between your low back and the wall – it should slide in easily and touch or almost touch both your back and the wall at the same time. If there’s a lot of space between the wall and your low back, you may have a swayback. Make sure your earlobes are directly over your shoulders and your shoulders over your hips for proper head/shoulder/pelvis alignment.

Now to correct your posture, imagine that a helium balloon is tied to the crown of your head, pulling you upwards; press your navel into your spine and tilt your hips back slightly so that the space between your low back and the wall is slightly reduced.  Try maintaining this posture as you walk away from the wall.  WARNING:  STANDING WITH CORRECT POSTURE MAY FEEL STRANGE AT FIRST!  IT MAY ALSO FATIGUE YOUR POSTURAL MUSCLES INITIALLY.

Improving Your Sitting Posture

Sitting for prolonged periods is one of the worst things you can do for your spine. But, since we all must sit, when you do so:

  • Keep your shoulders back and your head centered over them (ears over shoulders).  Don’t recline against the backrest of your seat or lean forward.
  • When driving, place a small pillow or lumbar roll at your low back and don’t hunch over the steering wheel.
  • Be sure to get up, stretch and walk around at least once each hour.  Place an alarm clock nearby to remind you.

Be Well (and sit up straight!),

Keys to Good Posture: Part I

November 21, 2009 by wellcoaching

In my last post I discussed a new research finding that improving your posture can boost your confidence. But practicing good posture doesn’t just benefit your self-esteem, it’s also essential for the health of your spine.

The average person spends several hours each day sitting, which compresses the spine and tenses the back muscles.  Slouching further increases the pressure on the lower back 10-fold. Hunching over a desk, computer or steering wheel also tenses the muscles in the upper back and neck and can lead to neck pain and headaches. Good posture, on the other hand, helps diffuse pressure on the spine.

The following are typical signs of poor posture:

  • Protruding abdomen
  • Slumped or rounded shoulders
  • Swayback (excessive forward curve of the lower back)
  • Forward neck and head (chin extended too far in front)

The following are typical causes of poor posture:

Muscle Imbalance:

  • Chest muscles are tight and overdeveloped while upper back muscles are weak and overstretched  – leading to kyphosis (hunchback)
  • Abdominal muscles are weak and hip flexors are too tight – leading to lordosis (swayback)

Muscle Fatigue:

  • Muscles tire from sitting or standing too long in one position and as a result of deconditioned muscles

Here are some tips for correcting poor posture:

  • Align your earlobes over your shoulders and your shoulders over your hips, your hips over your heels.
  • Keep your stomach and buttocks tucked in, your chest and rib cage lifted, your shoulders back and your chin level and slightly pulled inward.
  • Note that the three slight natural curves of the spine are part of a good standing posture:  a slight forward curve in the low back; a slight backward curve in the upper back; and a slight forward curve in the neck.

In my next post I’ll specifically discuss how to realign your spine and stand and sit with good posture. Until then….

Be Well,

Carolyn


Stand up Straight and Boost Your Confidence

November 14, 2009 by wellcoaching

A new study from Ohio State  found that simply sitting up straight and practicing good posture can increase self-confidence. What I find so interesting about this study is the idea that simply changing body position can alter mood. 

People who have good posture usually come across as naturally confident, but if this research is correct, it could be the act of standing up straight that is also boosting their self-esteem. So it’s sort of a chicken or egg question.  There has also been research that smiling can improve your mood, even if you’re not feeling happy to begin with.

I love the idea that practicing good posture can boost self-confidence since it’s something that’s good for us anyway. In my next posts I will first discuss the signs and causes of poor posture and then offer some tips for good posture. Until then…

Be Well,

Carolyn

Is Technology Really Drawing us Closer? Only Superficially

November 11, 2009 by wellcoaching

New research from the Pew Internet & American Life Project says that not only has technology not increased social isolation, but that regular internet and cellphone users are better connected with a wider network of social contacts.

OK – that may be true, but how meaningful are these social contacts? Having dozens of “friends” on Facebook, or regularly communicating with others in chat rooms does not a relationship make. What I found most troubling was the finding that the number of days in a year people contact their family/friends via cellphone (195 days) was only slightly less than the number of days they had face-to-face contact (210 days).

I’ve said it before and I’ll say it again, we are in danger of losing the art of human interaction. Human beings are social animals – biologically we need to be together physically. Yet, increasingly we are conversing with family, friends and strangers without ever looking them in the eyes (a.k.a the  ”windows of the soul”). I’m not as concerned for those of us who weren’t raised with cellphones, the internet or even PCs, but I fear that young people today aren’t learning the social skills they need to establish healthy relationships in the real world, not the virtual one. 

The Pew researchers also found that internet users are more likely to go to seek out public places: “45 percent are more likely to visit a cafe and 52 percent are more likely to visit a library”. That may be true, but it doesn’t mean they’re interacting with others. Go to any Starbucks and you’ll find the majority of patrons sitting alone, staring into their laptops or intently punching the buttons of their blackberries. In fact, here in my community, there is a cafe which encourages their patrons to log on to their website to “chat” with other patrons in the cafe!!! Yes, actually chat on-line rather than pull up a chair when they’re just steps away from one another!! While there’s nothing wrong with making contacts on-line, true friendships need to be developed off-line, in-person. 

Even at a potentially social place such as a gym people are plugged to their I-pods, sometimes even during a group exercise class. If they’re not going to interact with other gym-goers – why not just exercise at home?

It’s possible to be in a room full of people and still feel very alone and, according to the experts, that can be as harmful physiologically as it is psychologically. According to Dr. Barbara Brehm, professor of exercise and sports science at Smith College, “When you feel isolated, you get the same neuroendocrine and immune response as when you’re under (chronic) stress. You may have higher cortisol levels, which may lead to heart disease, high blood pressure and stroke.”

On a more positive note, the Pew team found that bloggers are 72 percent “more likely to belong to a local voluntary association” than those who don’t blog. Volunteering is a great way to connect with other people and contribute to the community at the same time.

Speaking of volunteering, if you follow my blog you know I’ve written about the recent rash of teen suicides in my community. A group of concerned adults have now banded together to form “Track Watch“, a volunteer organization of community members who, in an effort to prevent further tragedies, conduct a nightly vigil at the train tracks where the suicides took place. I commend these people for taking the time to demonstrate to young people that they care. Furthermore, by showing up (in person) the volunteers also derive emotional support from one another. Coincidence or not, since Track Watch was formed, there have been no suicides or even attempted suicides. 

Be Well,

Carolyn

Women Catching Up to Men in Heart Disease

November 7, 2009 by wellcoaching

New research has found that while middle-aged men still have higher rates of cardiovascular disease, women are unfortunately catching up.

Men still have more heart attacks than women, but that gap is narrowing. The study found that while men’s rate of heart attacks declined, women’s rate  increased. Furthermore, among middle-aged American women (ages 45-54), stroke prevalence was double that of men of the same age group.

On a positive note, another related study found that women’s rate of survival from heart attacks and strokes have improved.  For women younger than 55, the study found the risk of dying has dropped by 53 percent. The researchers theorize that this due to an increase in the awareness of physicians in screening middle-aged female patients for heart disease and/or the greater awareness among women of their potential cardiovascular risk.

On the other hand, the researchers believe that the narrowing of male-female heart disease rates is due to better control of cardiovascular disease risk factors (high LDL and low HDL cholesterol, high blood pressure, smoking, obesity and diabetes) in men than in women. The researchers also point to the fact that women now make up a significant portion of the workforce, their stress levels have increased and their time for exercising  has decreased, resulting in greater rates of obesity and diabetes. Furthermore, while female hormones have thought to protect women from cardiovascular disease prior to menopause, the rising rate of female obesity (higher in middle-aged women than men) may negate that benefit

So now that men no longer corner the market on heart disease, it’s even more important to note that women’s warning signs for heart attack and stroke can be different from those of men. All the more important for women and their physicians to be aware that cardiovascular disease is an equal opportunity destroyer. Furthermore, doctors need to remind their female patients of the importance of prevention:  exercising, controlling weight, avoiding smoking and limiting dietary saturated fat and refined carbohydrates.

Be Well,

Carolyn
