BENEFITS OF "BOO!"
A Good Scare Can Boost Immunity

Could a Halloween fright help you fight winter colds? A new study from Ohio State University suggests the idea might not be as far-fetched as it sounds.

Limited bouts of stress may not only help you resist infection in the short term, it may enhance immune activity for weeks and even months on end, according to animal research. Exposure to acute stress triggers an increase in the number and activity of T cells – a type of white blood cell that selectively searches out and destroys infectious agents like germs and viruses.

The response makes evolutionary sense: The sight of a predator provokes fear, which in turn prepares the immune system to resist infection from possible injury. Is what's good for the caveman good for the corporate exec? Yes and no. As explored in a previous DNN, stress in short doses can do your body good, promoting longevity by preventing the accumulation of damaged proteins. But chronic stress can undermine your immune system, aggravate arthritis, increase abdominal fat and even age you at a cellular level.

Bottom line: Occasional crises might strengthen your immune system, but keep your inner stress puppy on a short leash. Click here for our top ten ways to chill out.

PERSEVERE AGAINST POUNDS
Without Vigilance, Most Will Be Fat

"Never give in, never give in, never, never, never!" Churchill's famous exhortation in the fight against fascism could equally apply to the battle of the bulge. Let down your guard – let out that waistband – and odds are you'll end up overweight, according to Boston University (BU) researchers

The study, which followed 4,000 normal weight people aged 30 to 59 for three decades, suggests that over the long haul, 9 out of 10 men and 7 out of 10 women will become overweight. "You cannot become complacent," observes lead author, Ramachandran Vasan, Associate Professor of Medicine at BU, "because you are at risk of becoming overweight."

The BU findings suggest that obesity may be a greater problem in the U.S. than previously thought, as earlier estimates focused on a single point in time – not the overall likelihood that a person will become overweight or obese. Such so-called "snapshots" have delivered a 7 out of 10 rate for men (vs. the "overall" 9 out of 10) and a 6 out of 10 rate for women (vs. the "overall" 7 out of 10) of being overweight.

Excess weight raises general health risks for a variety of diseases, such as diabetesheart disease, stroke, and osteoarthritis. It also poses gender specific risks such as higher rates of ovarian, breast, cervical, and uterine cancer in women, as well as an increased risk of stomach and prostate cancer in men. Since men carry their extra weight in the midsection, they may also fare worse than women in terms of carbohydrate intolerance and diminished exercise endurance.

If vitality and vanity aren't enough to keep you motivated in the fight against fat, how about a better sex life or cash incentive? Avid DNN readers may remember that dropping pounds can lift your libido and possibly fatten your wallet as well. 

Bottom Line: New research suggests most people will become overweight or obese – so eat better and increase activity to be one of the few, the proud, the trim.

YOGA YIELDS RESULTS
Fight Fat, Bust Stress, Sleep Better

Yoga has long been recognized as a path to greater peace. Now this ancient premise gets modern proof with research revealing a drop in levels of the stress hormone cortisol after just one yoga session. While cortisol levels have been linked to increased abdominal fat, the claim that yoga can aid weight management has remained mostly anecdotal...until now.

A Seattle study, involving over 15,000 subjects, found that yoga practice helps check middle age spread. Overweight subjects who did yoga at least once a week over the course of a decade lost eight pounds – while their non-yoga practicing peers gained an average of fourteen pounds during the same time period. This result bolstered findings from a previous, smaller University of Pittsburgh study of 59 obese women who lost more weight (an average of 27 pounds) after four months of yoga, walking and a low-fat diet than those who did strength training or just walking alone.

While this research should encourage you to incorporate yoga into your exercise routine, it doesn't mean that 'Downward Dog' is all you need to do to stay fit. Researchers from Texas State University found that while some of the more vigorous moves, like Sun Salutations, burn up to 4 calories a minute (the equivalent of a brisk walk), most yoga disciplines fall short of delivering the overall cardio benefits you'll get from traditional aerobic exercise (e.g. biking, jogging, swimming, etc.). Your best bet is to strive for a varied regimen that will yield the full range of fitness benefits: endurance, strength and flexibility.

Bonus: Yoga might even help you rest easier. Participants in an eight week Harvard Medical School study, who did yoga for 30-45 minutes a day, fell asleep 30% faster and woke 35% less than the control group. So greet the day with yoga to find yourself saying "namaste" at night.

PUMPKIN FOR YOUR PEEPERS
Halloween Superfood For Eyes, Lungs, Joints

While jack-'o-lanterns light the trail of trick-or-treating, regular consumption of pumpkin could help you see better in the dark. One cup (116g) of raw pumpkin contains over 170% of the Daily Value of vitamin A – a powerful nutrient needed for night vision – plus other eye-healthy phytonutrients such as lutein and zeaxanthin, making pumpkin a powerful Superfood for your eyes.

The alimentary abundance of the orange orb doesn't stop there. It offers one of the best sources of beta-cryptoxanthin, a carotenoid linked to lower lung and prostate cancer risk, as well as improved joint health. In fact, a recent British study found that people with the highest intake of beta-cryptoxanthin had half the risk of developing polyarthritis (inflammation that affects at least two or more joint groups) compared to those with lower consumption levels.

Pumpkin also provides a good source of potassium (to help regulate blood pressure) and vitamin C (to help promote collagen formation) – all for only 30 calories per cup of raw. Haven't got the patience to gut that gourd? Pop a tin of canned pumpkin – one half cup of which provides nearly 400% of your daily vitamin A needs, plus a quarter of your daily vitamin K needs, for just 42 calories!

If these health benefits aren't motivation enough to put pumpkin on your menu, how about getting in the "food for love?" As discussed in a previous DNNresearchers at the Chicago-based Smell & Taste Treatment and Research Foundation exposed male subjects to a variety of different aromas – among which the scent of pumpkin pie turned out to turn men on.

So, try our featured Superfood recipe, Pumpkin Pineapple Mousse Pie, to improve your health – and spice up your love life.

LOVE YOUR LIVER
Top Ten Tips for Liver Health

Ask what observances October brings to mind and most will answer Halloween – or perhaps Oktoberfest. The first is celebrated with candy consumption, the second with beer drinking – both of which, in excess, are at odds with October's lesser known identity as National Liver Awareness Month.

While many know that alcohol abuse can damage the liver, a new study from Johns Hopkins University found that eating loads of sugar and fat could also put your liver at risk. The animal research suggests that liver function already compromised by injury is further undermined by high-fat, high-sugar diets. This news represents further progress in the fight against what is rapidly becoming one of the nation's most serious public health problems – liver disease, which includes hepatitis, cirrhosis and cancer.

The largest intestinal organ, liver detoxifies the blood, stores glycogen for energy needs, and secretes bile that aids fat digestion (just to name a few of the liver's more than 500 functions). So how do you keep this vital organ in optimum health? We've assembled a top ten list of dietary tips to "love your liver." After all, while moderns associate "love" with the heart, Elizabethans looked to the liver as the seat of passion. Follow this list, and your liver will likely love you back:

1) An Apple for Your Innards: Cornell University researchers found liver cancer cells treated with 50 mg of apple extract decreased cancer cell growth by 57%.

2) Make Time for Tea: Compounds contained in green tea may help rehabilitate livers damaged by excessive alcohol consumption, according to animal studies conducted at the University of Chapel Hill. Another study from the University of Hong Kong found green tea catechins could reduce inflammation and free radical damage in the event of liver injury.

3) Eat Your Greens: A team of UK and Japanese researchers report that those who eat green vegetables regularly (daily or almost daily) were significantly less likely to die from liver cancer. Try arugula, spinach, kale or romaine lettuce.

4) Avocado is King: In one Japanese animal study, avocado beat out 22 other fruits as the best defense against liver damage. Another study from the same researchers found avocados appear to lessen the liver damage caused by hepatitis C in rats.

5) Spice It Up: A 2003 study published in the American Journal of Physiology found that rats fed curcumin (a compound in turmeric, the yellow spice used in most traditional curries) were protected against alcohol-induced necrosis of the liver.

6) Plum Healthy: Research shows that a phytonutrient found in plums, chlorogenic acid, may block the formation of carcinogenic nitrosamines during digestion and reduce the risk of liver cancer. Other top sources of chlorogenic acid include cherries, apples, and blueberries.

7) Onions – Stronger the Better: Cornell University researchers found that strong flavored members of the onion family – such as New York Bold, Western Yellow, and shallots – are the best varieties for inhibiting the growth of liver cancer cells.

8) Astounding Artichoke: European researchers found that a flavonoid called silymarin, found in certain artichokes, could help reduce mortality rates among alcoholics with cirrhosis of the liver.

9) Reduce Alcohol Consumption: When you overload your liver with alcohol, all of the organ's resources are going to burning off the booze. This can lead to a fatty liver, reducing the liver's ability to filter out toxins, which eventually spill over into the bloodstream. Women in particular must limit liquor consumption because they experience liver damage earlier than men.

10) Lose Weight:
Not only can liver toxicity lead to excess weight – excess weight can lead to liver problems, significantly increasing your risk of developing nonalcoholic fatty liver disease (NAFLD)
Another weight related ailment, diabetes, may also increase the risk of liver diseases. NIH researchers found the incidence of chronic liver disease and cancer of the liver in diabetics was about twice that of patients without diabetes.

MISSING NUTRIENTS
Where Our Diets Fall Short

You don't need a sophisticated survey to establish that most Americans are overfed – a casual look around will suffice. What may not meet the eye is that while most of us are getting more than we need in terms of calories, refined carbohydrates, saturated fat and sodium, we're curiously undernourished when it comes to key nutrients. Recent reports issuing from the U.S. Department of Agriculture (USDA) found that we fail to meet recommended daily allowances for a host of vitamins and minerals.

Regular DNN readers know what they need to eat everyday -- and why, having perused our highly popular brochure on the subject (also available in Spanish). Visitors to www.dolesuperfoods.com also know which foods are "super" sources of nutrients that provide targeted health benefits for your eyes, skin, heart, joints, etc. What you may not  know is where you're in danger of falling short of dietary recommendations. Well, we're here to guide you.

DNI researcher Alex Russell plumbed the data, pulled out the five most glaring nutrient deficiencies in the American diet, and assembled the following chart. In addition to explaining why the missing nutrients are important, our guide to "what you need -- and aren't getting" also identified top sources of each.

Fiber, potassium, magnesium, vitamins A and E aren't the only nutrients that are slipping through the cracks. Americans are also failing to get enough vitamin C and calcium -- while some sub-populations are short on other key nutrients. Read on to find out if you're at risk of certain nutrient deficiencies.

  • One surprising nutrient deficiency is vitamin C, which is lacking in 40% of men and 38% of women 19 or older -- surprising because it’s so easy to meet (e.g. half of one red bell pepper provides well over 100% of the daily requirement).  Vitamin C promotes collagen formation, immune function and wound healing. Top sources of vitamin C include red/yellow bell peppers, kiwi, oranges, and broccoli.
  • Calcium deficiency is also pervasive, with one half of women and 40% of men failing to get enough. Calcium promotes strong bones and teeth. Top sources of calcium include nonfat milk, soybeans, kale, and arugula. 
  • One-third of people over 70 years old do not get enough zinc. Zinc helps boost the immune system and may reduce cold symptoms. Top sources of zinc include oysters, beans, oats, and green peas.
  • Almost one-third of adult women do not meet the daily vitamin B6 requirement. Vitamin B6 may reduce the risk of heart disease, help make red blood cells, and support normal brain and immune function. Top sources of vitamin B6 include potatoes, bananas, red bell peppers, and broccoli. 
  • About 15% of women 14 to 50 years old fall short on iron. Iron is needed to oxygenate the blood and support reproduction. Top sources of iron include cooked clams, spinach, green peas, and soybeans.
  • Forty percent of young women (ages 9-18) do not get adequate phosphorus. Phosphorus works with calcium to promote strong bones and teeth. Top sources of phosphorus include lentils, sardines, salmon, and Portobello mushrooms.

BREAST CANCER IQ

Over 350 readers took part in our Dole Poll aimed at measuring breast cancer awareness. But how's your know-how on your risk?

Nearly 70% of readers got it right when they picked "1 in 8" as a woman's chances of developing breast cancer over her lifetime (15% thought chances were 1 in 15 and another 15% thought chances were 1 in 3).

Our DNN readers' correct response rate is pretty impressive, since the general public tends to overestimate a woman's odds of breast cancer. (In one poll 90% of women thought the average risk was nearly 50%!)

However, only 15% of our readers guessed what percentage of women diagnosed with cancer are under 45 years old: the correct answer is 5%. More than a quarter of our readers thought 40% of women diagnosed with breast cancer were under 45 – while the vast majority of readers (nearly 60%) thought 15% of women diagnosed with cancer were under 45 years old. All these percentages can be confusing, so to repeat, the correct answer is that only 5% of women diagnosed with breast cancer are under 45 years old.

While it's some relief to know that so many of us may have overestimated the risk to women under 45 – it's important that all women, and men for that matter, understand the factors that contribute to increased risk of breast cancer.

The good news here is that nearly all of our readers know that excessive alcohol consumption, high fat diets and smoking are all risk factors for breast cancer. More than 40 studies link alcohol abuse to increased risk of breast cancer. Countries with the highest fat diets also have highest breast cancer rates. Finally, smokers are more than twice as likely to develop breast cancer as nonsmokers.

DO YOU DO WHAT DOCS DO?

A recent survey of the Harvard Medical School faculty found that in the main, doctors practice what they preach. Before we reveal their survey results let's see how DNN readers fare when matched against MDs in terms of healthy behaviors. We'll pose some of the same questions, then compare DNN responses with the docs' in our next issue.


How often do you buy a meal at a fast-food restaurant?
Never
Rarely
Two or three times a week
More than three times a week
Do you eat breakfast?
Yes
No
Do you exercise at least 3 times a week?
Yes
No
Do you take a multivitamin?
Yes

No


Finally, here's a twist on one of the questions. Doctors were asked whether they regularly talk to their patients about diet. Since most of us have been patients at one point in our lives, tell us: Do your doctors talk to you about your diet?
Yes, my doctor talks to me about proper diet
No, diet and nutrition do not come up
