Children and teenagers -- mostly girls -- need zinc, a mineral important for maintaining healthy immune systems and healthy skin and for preventing colds and infections. Yet half of all teenage girls have zinc deficiencies.

Red meat is the most effective way of channeling zinc into the body. Perhaps these young girls are eating red meat less than two times per week -- a practice research shows can contribute to zinc deficiencies.

Iron is vital for good health. Menstruating women need it. The elderly need it. Pregnant women need it. And children need it too. But many lack healthy levels of iron.

Red meat contains a lot of iron. And while iron also comes from vegetable sources, meat contains more iron than most foods and is best utilized by the body in this form.

Red meat also contains B vitamins, phosphorus, potassium, magnesium, selenium -- and protein, critical for muscle and organ health. Protein from red meat is complete, meaning it contains all the amino acids the body cannot make on its own. Protein helps the body repair and renew.

There is definitely a good side to eating red meat. There is also a bad side.

Red meat has been linked to incidences of bowel cancer, breast cancer, heart disease, Alzheimer's disease, osteoporosis, arthritis, high cholesterol, clogged arteries, and food poisoning.

Experts say the controversy surrounding red meat comes down to the type of meat we are eating -- and how we are eating it.

There are three official red meats -- pork, lamb, and beef. Pork is the leanest, lamb is the fattiest, and beef is the most nutritious. Red meat is typically high in saturated fats and bad cholesterol. But lean beef is fairly healthy -- if it's not treated with hormones and is truly free from excess fat. The more white you see, the more fat you get.

So here is the trick for all meat-eaters out there -- choose lean meats, seek nutritious cuts of meat, avoid hormone-treated products, steer clear of processed meats (these include more additives and fats than simple cuts of pork, lamb, and beef), read labels carefully, make meat just one component of a balanced diet, and brace yourself for more research and study and discussion that will undoubtedly conclude that meat is good for us. And bad for us too.

Prescription drugs purchased online from Canadian pharmacies were intercepted before they reached the US, and after preliminary laboratory tests were found to be counterfeit. The U.S. Food and Drug Administration (FDA) is warning consumers who may have obtained prescription drugs from Mediplan Prescription Plus Pharmacy or Mediplan Global Health in Manitoba, Canada not to take the medication as it may not be safe.

The drugs in question are Lipitor, Diovan, Actonel, Nexium, Hyzaar, Ezetrol or Zetia, Crestor, Celebrex, Arimidex, and Propecia. Most of the drugs are prescribed for cholesterol disorders and high blood pressure; Actonel for osteoporosis in postmenopausal women; Nexium for gastroesophageal reflux disease; Celebrex for arthritis-related pain; Propecia for male-pattern baldness and Arimidex is a breast cancer chemoprevention medication.

Interestingly, the FDA conducted an investigation last year and discovered that nearly half of the imported drugs they confiscated from four selected countries were shipped to fill orders that consumers believed they were placing with Canadian pharmacies. The drugs did not come from Canada. According to the FDA, 85 percent actually came from 27 other countries around the globe. Buyer beware.

I have tried to exercise most of my adult life -- at times because I felt obligated to participate in what I knew was good for me and at times to justify eating my favorite foods while maintaining an appropriate weight and at times because I wanted to actually have a toned, healthy body.

At this exact time in my life, I exercise with all of these motivations in mind -- plus a few more. I like to sweat and know I am accomplishing a physical feat. I like the mental release I get when I push my body to perform. I like the time to myself, the loud music I hear on my MP3 player, and the results I see from a little bit of hard work. And lately -- as a result of a new weight training program -- I know I am benefiting my body more than ever before.

The following are just seven of the many gifts that come from weight training. Gifts that will make me a happier, healthier cancer survivor.

Noticeable physical results -- Mostly, walking and occasional jogging have been my methods of exercise. And I've seen results from this type of workout -- leaner legs, more defined calf muscles, and the knowledge that I am increasing my cardiovascular health, as confirmed by the technician who performed an ultrasound on my heart in preparation for my Herceptin treatment for breast cancer. He told me he could tell I exercised regularly because of my low resting heart rate. But until I started weight training a few months ago, I never witnessed quick results. Yet after a few weeks of resistance exercise -- lifting 20-pound weights for my arms, shoulders, back, and chest -- I could see definition and tone that clearly would not have resulted from my purely cardio workouts.

Improved strength and endurance -- Lunges and squats and jumping with resistance bands have strengthened my legs. Lifting weights has strengthened my arms -- and I can now lift heavier weights than when I first started my new routine. I can do more push-ups now too -- not girl push-ups on my knees but real push-ups -- than I ever could have imagined doing when I could barely lower my own body weight and would crash to the floor on my stomach. My strength has improved. My endurance has improved. I feel more powerful.

Increased energy -- Fatigue (or maybe it's laziness) sometimes prevents me from happily jumping up to begin exercising. But when I push myself and exert myself and get lost in my exercise routine, my energy returns -- and not just during my workout but for some time afterwards too. Some say energy increases from strength training because it contributes to loss of fat which means we have less to lug around each day.

Burning of more calories -- Weight training raises basal metabolism which causes more calorie burning over a 24-hour period of time. Calories even burn during sleep as a result of weight training.  For every additional pound of muscle you gain, your body burns 50 extra calories every day -- 50 more calories than the few hundred that might burn from aerobic exercise. Research shows that regular resistance training can increase your Basal Metabolic Rate by 15%. So for someone who burns 2000 calories per day, that's upwards of 300 extra calories burned every single day. 

Decreased onset of illness -- Weight training can reduce the risk of adult onset diabetes and the risk for developing colon cancer and can improve the functioning of the immune system and the efficiency of the heart. It decreases the risk of low-back injuries, decreases resting blood pressure, increases good cholesterol (HDL), and improves posture. The list goes on -- and so does healthy living if weight training becomes a way of life. As a young person already having experienced a life-threatening illness, this comforts me.

Prevention of osteoporosis -- My recent bone density test revealed that I am not at this moment at risk for developing osteoporosis. I don't want this to change. Strength training can help me maintain this status because it can significantly increase bone mineral density -- which is important because we naturally lose bone density as we age. Strength training helps protect against osteoporosis. And age should not be a deterrent. Individuals who begin training late in life -- at age 65, for example -- can restore bone loss.

Improved outlook on life -- As a result of toning and shaping my body, burning calories, enjoying greater strength and energy, and working toward a disease-free future, weight training gives me an improved outlook on life. And weight training has recently been reported to significantly improve the quality of life of women recently treated for breast cancer. A May 2006 study indicates six months of twice weekly exercise was enough to improve the overall physical and emotional condition of patients.

Twice weekly is my weight training goal. I will continue to walk and run -- and bike on occasion too -- but strength training will be my priority. Because health is a priority.

A study done to compare the benefits and risks of two different drugs used to treat invasive breast cancer found both effective, but with slightly differing side effects. Researchers conducted a trial at nearly 200 clinical centers across the country. The women chosen for the trial were at an increased risk for breast cancer. The 19,747 postmenopausal women in the study were either given tamoxifen or raloxifene for five years. At the end of the study, tamoxifen and raloxifene seem to offer the same level of benefit in breast cancer prevention. The group of women on tamoxifen had slightly more uterine cancer diagnosis and lung or deep vein blood clots than the group of women on raloxifene, but not in significant numbers.

However, tamoxifen is seen by primary care physicians as a toxic chemoprevention drug, where raloxifene is seen as a fairly safe drug. Raloxifene is currently prescribed for the prevention and treatment of osteoporosis in postmenopausal women. According to the researchers, "This trial confirms the previously reported benefit of raloxifene in reducing the risk of invasive breast cancer and indicates that raloxifene is as active as tamoxifen in this regard. If raloxifene is approved by the Food and Drug Administration for the prevention of breast cancer, primary care physicians may be more willing, given their experience with raloxifene, to prescribe it for breast cancer chemoprevention than they have been to prescribe tamoxifen."

Out of New Zealand comes reporting that four New Zealanders have suffered rotting jawbones after taking a bisphosphates medication prescribed to help prevent bone loss for patients suffering from osteoporosis and bone cancers. At least 15 Americans are suing Merck after developing breakdown of bone in the jaw due to taking Fosamax prescribed to strengthen bone and prevent bone loss.

According to the report, while the New Zealand patients were not taking the brand name drug, Fosamax, they were taking a similar version of the same drug. In total, about 2500 cases of rotting jaws have been reported. Merck is the same company who was forced to take Vioxx, an arthritis drug, off the market after a study showed it doubled the risk of heart attacks or strokes if patients took it for longer than 18 months. Perhaps we need to take a closer look into the medicine cabinet -- and start asking more questions -- before we rush to get a glass of water and down the newest approved pill. A new cancer drug is about to hit the market. Let's take a look.

Jane Plant, one of Britain's leading scientists, a bestselling author, and five-time breast cancer survivor speaks out against the cancer risks of dairy products, and in favor of a cancer prevention plant-based diet. Professor Jane Plant claims that milk contains growth factors and hormones that can promote cancer. Her controversial message that breast cancer can be treated, and even prevented, effectively by simple changes in diet has been met with huge acclaim from hundreds of thousands of sufferers of breast cancer around the world. She has written four books, Your Life In Your Hands - Understanding, Preventing And Overcoming Breast Cancer; Eating for Better Health: The Plant Programme; Understanding, Preventing And Overcoming Osteoporosis and Prostate Cancer - Understand, Prevent And Overcome.

According to Dr. Plant, a plant-based diet and lack of dairy is the norm in Far Eastern countries and the incidence of being diagnosed with breast cancer are half that of western nations. As an example, when Chinese and Japanese women move to Europe or the United States and adopt the western diet, they begin to experience a dramatic increase in breast cancer rates. As a breast cancer survivor, and cancer-free for eleven years, Dr. Plant will take part of The Vegetarian and Vegan Foundation White Lies campaign launch as a featured speaker, along with Heather Mills McCartney and Dr. Campbell of The China Study.

University of Pittsburgh Medical Center researchers are recommending that men treated for prostate cancer be given the same medical treatment women, who are treated for hormone-positive cancers, receive to prevent bone loss. The same hormones that feed hormone-driven cancers, are the same hormones that help maintain bone density. While chemoprevention cancer therapies block these hormones from advancing hormone-positive cancers, the downside is the known side-effect of bone loss. Bone loss, or osteoporosis, is a serious concern because it can lead to brittle thinning of the bones and easy bone fractures. Men treated with androgen deprivation therapy for prostate cancer, who were then given alendronate, a drug used to treat osteoporosis, showed significantly increased bone mass compared to men who did not receive the drug.
