Radiation's Side Effects

More than half of all cancer cases are treated with radiation, a first-line treatment for many cancers like head and neck, lung, breast, and prostate cancer. A major side effect of radiation, though, is the damage caused to healthy organs and tissues. Now new therapies are not treating the cancer, but the side effects of the treatment.

Mary finds happiness in her garden. "I just love to be outside. And I mess around in one little spot awhile. Then I'll go to another one," she says.

Last fall, gardening was the last thing on her mind. She says, "I was diagnosed in September. I had felt a lump on my neck. What the doctor was saying, I really just could not comprehend."

Diagnosed with squamous cell carcinoma, she faced surgery, radiation therapy, and a handful of unwanted side effects. Mouth sores, skin reactions, dry mouth and loss of taste are all side effects of radiation.

Radiation oncologist are trying to keep those side effects to a minimum.

Anything that you can do to make the short-term or long-term quality of life better is an improvement in cancer care.

Enter amifostine. Given intravenously, it prevents dry mouth.

Amifostine is a radioprotector for the head and neck. One reason it's so good there is that it is taken up more in the salivary glands than in other tissues.

Biafine cream is another product that can alleviate common skin reactions.

Most patients that are undergoing a course of radiation may have some skin reaction, redness or swelling.

Mary received amifostine and Biafine cream. Both worked, allowing her to focus on things that are more important.

Doctors are also studying a new mouth rinse to treat the painful mouth sores that come with radiation therapy. Amifostine is already FDA approved to treat the unwanted side effects of radiation for certain cancers while Biafine cream is still in clinical trials for head and neck cancers.

The Case for Physical Fitness

Deciding to step up your physical activity is a great move for your health. It will take you to exciting destinations — like elevating your mood, increasing your energy, improving your sleep, and helping you manage stress.

Elevate Your Mood
With skyrocketing costs, hectic schedules, and the stressors of everyday life, it’s easy to develop a glass-half-empty mindset. But daily exercise — aiming for at least 10,000 steps — can help you see your glass half full by:

Releasing endorphins — hormones that help boost your outlook
Alleviating depression and reducing anxiety
Balancing levels of serotonin, which creates a more stable frame of mind.

Increase Your Energy
Have you ever started your day energized and ready to go, only to be crashing by mid-afternoon? Many people experience this dip in energy. Not only is it a problem in how you feel, it also can hinder your work performance. You can beat the slump with consistent walking habits.

More effective than any caffeine drink, exercise can provide long-lasting energy. In a recent study, previously inactive people increased their energy by 20% and reduced fatigue by 65% through a regular workout routine. When you’re physically active, your body actually responds by generating more energy.

Improve Sleep
Head outdoors and walk in the daylight — it can regulate your body’s production of melatonin at night, allowing a deeper, more relaxing sleep. Studies also show that physical activity 3-4 hours before you go to bed can promote better quality sleep and a restful night.

Manage Stress
Everyone has stressors, and some may not be quickly or easily solved. In fact, some sources of stress may never go away. So what do you do? Get moving! Walking helps manage stress by:

Promoting a positive mindset; a good attitude is a serious force against stress
Giving you time to clear your thoughts and work through what’s bothering you
Managing your instinctual fight-or-flight response and providing a healthy way to expel negative emotions.
Aerobic activity (walking, running, swimming, or cycling) and flexibility workouts (yoga or Pilates) both reduce stress.

A Winning Strategy
The physical benefits of exercise are well known — it’s your biggest weapon against weight gain and helps prevent many conditions including high blood pressure, diabetes, and high cholesterol. But exercise also offers benefits that can’t be measured on a scale or by a doctor — like mood, stress, and energy levels. Improve your outlook and your health with a fun, flexible walking routine

Relieve Stress With Walking

If you’re like 80% of Americans, the sluggish economy has you sweating bullets. According to the American Psychological Association, 8 out of 10 Americans are downright harried about their personal finances and job outlook. Combine that with obligations that seem to kidnap every tick of the clock, and it’s no wonder counseling services as well as anxiety/antidepressant prescriptions are on the rise.

But there’s a better way to manage stress. Although exercise might seem like another time thief, it’s your body’s most natural response to tyrants of tension. As you face monetary and career concerns, family demands, and a congested schedule, biological signals trigger fight-or-flight instincts — telling your body to actively react to your situation. But since you can’t sprint down the office corridor every time the market plummets or karate-chop the water cooler if your company starts downsizing, your body deposits that energy back onto itself — in the form of physiological steam waiting to erupt.

In fact, 77% of US citizens report stress-induced symptoms like:

Upset stomachs
Headaches
Teeth-grinding
Tightness, painful muscles
Insomnia
Depression
Irritability.

A frazzled psyche also produces an abundance of the hormone cortisol — which hampers immune response, causes weight gain, and increases blood pressure, pulse rate, and deadly inflammation.

A Smart Move

Physical activity helps release unbridled angst by serving as an outlet for pressure. It also relaxes kinked muscles, increases nutrient circulation to the brain, and pours out endorphins — which help balance negative chemical surges with positive feelings of contentment. Some studies even suggest that fit individuals handle long-term stress better than their sedentary counterparts, which means you’re combating your current worries… and preparing yourself to fend off future ones. Certain exercises, like walking, create an opportunity for you to purge some of the consuming mental clutter, too — opening the door to problem-solving, creative inspiration, and critical thinking.

It’s time to take walking off your back burner of burdens and make it a priority for relieving your anxious mind:

Walk it off. If stress begins buzzing about, smack it away with a quick stroll. Even 10-minute increments can help redirect volcanic build-up. Responding with a quick jaunt also establishes a new habit — one that’s healthier than visiting the vending machine for comfort food. If you program yourself to be active when faced with stress, you’ll learn to call on exercise as your number 1 coping method.

Change your thinking. Give up the attitude that suggests exercise is either an expendable luxury or a disposable demand. Rework your walking routine to be a constant tap on your shoulder — one that invites you to take the long way to your desk, park on the other side of the lot, or mosey with your child to school. If you view every extra step throughout the day as a checkmark on your list of accomplishments, walking will feel less like a burden and more like a tool for empowerment.

Share the wealth. You’re not the only one biting your fingernails and losing sleep. Chances are your coworkers, friends, and family are all battling a case of the worries. Get moving with a companion and you’ll not only introduce an accountability factor, you’ll help someone else shake off the shackles of stress. Plus, walking with a partner gives you a chunk of time for conversation… so at the very least you can commiserate and share solutions.

Grain and bear it

MOST AMERICANS—more than 90 percent of the population—don’t eat enough whole grains. That’s according to researchers from the U.S. Department of Agriculture, who say in their “Healthy People 2010” report that a lack of whole grains has become the single most common dietary deficiency in America. Unlike refined grains, whole grains contain the entire seed grain: bran, germ and endosperm. Naturally low in fat, whole grains are an excellent source of complex carbohydrates, fiber and numerous vitamins and minerals (ones unavailable from other sources), as well as phytochemicals and antioxidants. Experts say that regular consumption of whole grains may lower the risk of heart disease, diabetes, obesity and cancer, and help to regulate blood pressure and keep gums and teeth healthy.

The American Heart Institute and the National Cancer Institute recommend that the average adult eat 25 to 30 grams of fiber, commonly found in whole grains, per day. Children need about half that amount. To boost consumption, you can switch to whole-grain bread, substitute whole wheat flour for white flour in recipes, add barley or quinoa to your favorite soup, bake with oatmeal and switch from white to brown rice. It’s also smart to read food labels. Choose breads, cereals and pastas with the word “whole” before wheat. Don’t be fooled by terms such as enriched, unbleached, bromated, stone-ground, seven-grain, 100 percent wheat, cracked wheat, multi-grain or organic. Whole wheat (or whole rye, oats or brown rice) should be the first ingredient listed.

Herb of the month – Chamomile



As anyone who has brewed up a cup of chamomile tea knows, this subtly scented flower is one of nature’s top stress-relievers. For centuries, the daisy-like bud, which typically boasts white petals and a furry yellow center, has been used to soothe nerves and help induce sleep. The ancient Egyptians prescribed it for colds, while the Romans both drank it as a tea and used it in incense. (The name “chamomile” is derived from the Greek word for “ground apple”). The species includes many varietals – from wild chamomile and the all-yellow Golden Marguerite to the beauty and wellness and industry-favored Blue, Roman, and Moroccan types – but nearly all contain the flavonoid chrysin, which can have anti-inflammatory, anti-anxiety, and anti-oxidant effects. Along with dominating the herbal tea shelves, chamomile is also a popular skin-care ingredient, thanks to its calming properties. Chamomile helps comfort and correct reactive, sensitive, and rosacea skin conditions by reducing inflammation and irritation.

• Jacobs’ Redness Diffusing Serum mixes the flower with arnica, calendula, and other herbs to help minimize the appearance of broken capillaries and sun damage
• Darphin Organic Chamomile Aromatic Care quiets skin that’s irritated or blotchy.
• Patyka’s re-launched organic Rosewood Milk Cleanser, a 2-in-1 cleanser and moisturizer, uses chamomile, jojoba, and shea butter to purify without the need for water (thus protecting skin form harsh tap water)
• Kimara Ahnert’s Chamomile Eye Makeup Remover Pads soothe tired eys and do away with dirt without stripping skin
• The Organic Pharmacy’s powdery Lavender & Chamomile Milk Bath calms cranky infants and adults. Or, you could just go old-school
• Harney & Sons’ potent Chamomile Tea contains whole dried flower heads from Egypt, and goes great with a couch of honey.


Vitamins and minerals support your overall health.

Feel Heart Smart?

A collaborative study between USANA and Boston University shows that supplementing with grape-seed extract and vitamin C can help improve cardiovascular disease.

Recently, some studies have suggested prescribing statin drugs to patients, all in the name of “preventing” cardiovascular disease (CVD). Does anyone else think this preventive treatment is a little heart dumb?

To further support USANA’s philosophy of using nutritional supplements as part of a heart smart lifestyle, the amazing USANA scientists recently conducted a study in conjunction with a research team at the Boston University School of Medicine. The study showed that some key nutrients in dietary supplements can actually be beneficial for patients who already have a form of CVD.

Study Background

Oxidative stress appears to impact the heart’s ability to effectively pump blood through arteries and blood vessels. We all know cutting down blood flow is NOT a good thing. Over time, this impaired function has been shown to be a critical factor in the progression of CVD.

Grape-seed extract and vitamin C have both been widely shown to provide significant protection against oxidative stress, as well as to have positive effects on blood pressure. The USANA/BU team suspected that the powerful antioxidants could support healthy blood flow through supplementation of these two key nutrients together.

What They Did

Researchers gave study participants, who were already diagnosed with CVD, either a placebo or 450 mg of grape-seed extract and 1500 mg of vitamin C, divided into two daily doses of two tablets. Blood samples were taken four hours after receiving the first dose, then again four weeks after taking the same dosage every day.

The researchers measured plasma levels of vitamin C, epicatechin (bioflavonoids), and plasma antioxidant reserve (PAR)—a measure of the blood’s resistance to oxidative stress. They also measured blood flow using fingertip peripheral tonometry (PAT). PAT is especially useful in measuring changes in blood flow because it focuses on the peripheral arteries in the fingertip. Making up the majority of the blood vessels in our bodies, peripheral arteries are those that are farthest from the heart. They are miniscule when compared to the arteries coming directly from the heart, so any noticeable changes are significant. Those with CVD generally do not show a healthy blood flow response when measured using PAT.

What They Found
In the treatment group, vitamin C, epicatechin, and PAR increased to varying degrees at all three time points measured, meaning all the antioxidant levels were improved. PAT blood flow response also showed significant improvement following the 28-day treatment relative to the placebo group.

These results suggest that grape-seed extract and vitamin C, working together, improve vascular function in patients with CVD, even in those tiny peripheral arteries. The results of this study were so impressive that they were presented to American Heart Association.

Now, you can share these exciting results with your friends and family, as well.

The New Veggie

Kale has successfully transformed its image as a bitter green that children were forced to eat before they were grated dessert, to the vegetable darling of chef kitchens. Why should you be eating seconds?

It’s a low-calorie powerhouse of nutrients

Kale is rich in Vitamin K and helps strengthen bones. The presence of numerous flavonoids also means kale is rife with antioxidant and anti-inflammatory benefits. Kale’s benefits extend to cancer risk reduction specifically (at least five different types) due to the Isothiocyanates (ITCs) made from glucosinolates. These same components are noteworthy for their role in the body’s detoxification process, which may also be how they help reduce cancer risk. Additionally, kale contains fiber, that especially when it’s steamed, encourages easy excretion from the body which results in lowering of excess bad cholesterol and aiding cardiovascular health overall. Tips on incorporating more kale into your diet: Use it instead of tortillas, add it to fresh-squeezed juices, or “shred it to replace cabbage and make a slaw”.

It’s an ideal snack food

Kick your potato chip habit with all-organic Rhythm Kale Chips. Hand washed and tossed with organic, vegan sauce mixes, the kale is dehydrated overnight at low temperatures so it remains packed with nutrients. Try these raw, crunchy snacks in whimsical flavors like Bombay Curry, Kool Ranch, and Zesty Nacho.

It’s easy to cook

Most cooks probably find kale challenging because they think they have to cook it to death to make up for the fact that it can be a little tough. Unfortunately this often means that they end up with kale that is gray and mushy, leaving only a bitter murky taste behind. Instead, cook braised kale, particularly when it still has some texture and care has been put into the braising medium Рrich, full, flavored stock, aromatic vegetables like carrot and onion, and a hint of vinegar just before serving. You can also prepare kale by quickly saut̩ing the leaves and cutting them into a fine chiffonade with garlic olive oil and crushed red chili peppers. The kale cooks up a vivid green and still has some texture but is tender because it has been cut down so much. Similarly, even raw kale can make a great salad with a simple vinaigrette of lemon and anchovy and a few shavings of Parmigiano-Reggiano.

Bag It

If you needed any further incentive to head to the grocery store with reusable bag in tow, it’s ChicoBag’s attractive Produce Stand collection. Not only do they make for a stylish transport home, but these three specially designed bags are made of fabrics intended to sustain the life span of fruits and veggies. Bringing home spinach or green beans? Grab the moisture-wicking hemp-cotton blend. Don’t want those carrots and broccoli to dry out? Then opt for the rePETe, made with 99 percent recycled PET. A rePETe mesh version, allowing ripening ethylene gas to escape, ensures oranges and potatoes remain at their freshest.

Control yourself (It’s easy)

Chilly temperature mean more time spent indoors and more time fighting the temptation to succumb to snacks lurking behind cupboard doors. Just because you can wrap yourself in a bulky cardigan and hide for a few months doesn’t mean your winter eating habits need to be out of whack. Brooklyn, who struggled with weight loss for years, comes to the rescue with the pragmatic Measure Up Bowl. Journaling and keeping track of all the excessive calories she was taking in helped Havey find the clarity she needed to make significant dietary changes. Reflecting this newfound sense of empowerment is the porcelain Measure Up Bowl featuring pre-measured portions on the interior, so you can savor a healthy amount of addictive pasta or cereal without guessing or messing up a measuring cup. Harvey’s smaller bowl is meant for more calorie-dense foods like ice cream and granola.
