Should You Take Supplements?


Often I am asked about supplements and their role in a healthy diet. My take is that while vitamins and minerals are essential to life, the human body cannot self sustain this requirement. Therefore, it is imperative that we eat a well-rounded, low fat diet in order to obtain an adequate variety and supply.

Unfortunately, Americans have become infatuated with supplementation. Mega-dosing has become a common practice for both athletes trying to improve their performances and the “average Jane or Joe” trying to compensate for inadequate nutrition.

Research indicates supplementation is ineffective in improving athletic performance in a well-nourished adult. That’s to say if you are eating well, taking additional doses of supplements won’t give you an edge.

In fact, excessive amounts of fat soluble vitamins (vitamins A, D, E and K) may prove toxic since they are stored in the body and not easily excreted. Even some water soluble supplements such as vitamin B-12 have been shown to cause toxicity in mega-doses.

While most individuals don’t “need” diet supplements, women are an exception when it comes to iron and calcium. To counter the loss of bone density associated with osteoporosis, women are encouraged to meet the RDA of 1,000 mgs. Further research suggests that youths and pregnant, lactating and postmenopausal women need 1,500 mgs a day.

While some women reduce their consumption of dairy products to avoid fat, they also decrease their chances of getting the calcium they need by this omission. Iron Deficient Anemia is another concern for active women because they lose iron through sweat and the menstrual cycle.  In these cases, supplementation may be helpful.

Experts agree that eating a healthy diet is best. Combining this with an inexpensive once-a-day multiple vitamin & mineral supplement is more than adequate insurance for getting your recommended daily allowances.

However, if you're unsure of your nutritional needs, seek the advice of your doctor, registered dietitian or pharmacist.


And always – Enjoy Your Life!

Simple Steps to Spring Forward Toward Fitness

Daylight savings time is a sure reminder that spring is just around the corner and there WILL eventually be an end to the winter weather. And while much of the country still dealing with bitter cold, here in Houston, we’re definitely ready for the warmer days. In fact, this is the time of year when you’ll find many of us increasing our outdoor activities and all too often push ourselves a little too hard. Unfortunately, what can result is often a few days of painful recovery time.

So, I've got a short list of suggestions to consider as you pursue your favorite warm-weather pastimes this season:

First, increase your activity level gradually— Pay attention to your body’s signals so you can avoid serious injury and don’t have to pay the painful price of overindulgence. Start slowly and do a little more each day and you’ll be up to speed in no time.

Warm up— Plunging into activity before you get your body warmed and ready is inviting potential trouble. Avoid possible sprains, torn liga…

Not tonight… I've got a headache.

Headaches… the perfect way to ruin a romantic rendezvous. No? With Valentine’s Day just around the corner, I thought I would talk about headaches and suggest ways to prevent this trouble maker from ruining not only your love life, but your daily life, too.

According to Web MD, 30 to 80% of the adult Americans suffer from occasional tension headaches. Some of these may have hereditary causes, while others can be caused by lifestyle or environment, such as poor posture, unhealthy eating habits, a high stress job, or a demanding home life. Any combination of stress-inducing factors could become the trigger, really.

That said, massage therapy may be your best secret weapon to keep headaches at bay. At the very least, massage therapy can help you deal with the pain while you determine the best approach to maneuvering through the mitigating factors that might be causing your headaches.

But don’t just take my word for it…
