A Beginner's Guide to Hiking

(SouthBeachDiet.com) Now that the weather is warmer it’s easy to head outdoors to exercise. And if you’re looking to take your walking routine up a notch, why not hit the trails and try hiking? Whether you live in a big city, the suburbs, or in a rural area, you can easily take a hike through a local park, a woodsy part of town with well-marked trails, or on the beach (sand makes for a great workout!) — or check out Rails to Trails to find old railroad tracks that were converted to trails in your area. Hiking not only challenges your muscles in new ways and … it’s also a great opportunity to get in touch with nature, relieve stress, and enjoy the fresh air. Not to mention it’s a fun family-friendly activity! If you’re a hiking newbie, follow these tips before you head outdoors:

1. Pack water and healthy snacks, such as nuts, reduced-fat mozzarella cheese sticks, or peanut butter and whole-wheat crackers…

2. Wear comfortable clothing and appropriate shoes that can handle the trails and terrain…

3. Bring a map of the trail if possible. Remember to check the weather and trail conditions before you start your journey to ensure a safe trip…

4. Start with a half-mile hike round-trip and less than 500 feet in elevation gain if you’re not in condition. As you build your endurance you’ll be able to hike longer (or steeper).

5. Bring along a first-aid and emergency kit for longer hikes. Make sure it includes a safety blanket, bandages, a flashlight, a small pocket knife, sun-block, insect repellent, and waterproof matches.

6. Always tell someone where you’re going and who you’re with in case of emergency. That way, if something happens, there will be someone who can help locate you.

HEAD TRANSPLANT CURES WEIGHT PROBLEM

(Roger Gould, M.D., Shrink Yourself) That’s what a patient told me the other day.

“I feel like I have had a head transplant. My cravings are gone, my obsession with food and weight which I have had for over thirty years, is gone. I have such mental clarity now, I can’t believe the fog I have been living in all these years. And I am losing weight without even trying, and I'm not even dieting.”

Did she have a head transplant? Not exactly, but she was "cured" of her obsession with food, and when relieved from the burden of that preoccupation, her mind expanded instead of her waistline.

I have been talking about this for years in my book and in the Shrink Yourself program. The weight problem, the reason most people come to our site, can only be mastered AFTER the obsession with food is gone. I have hesitated to call this a “cure” because everyone is not cured at the same rate. However, for those who are rid of their obsession with food, it seems like a miracle, it feels like a head transplant.

Hip-hop video says healthy eating is cool

(UPI) A senior film student at the University of Alabama at Birmingham created a 60-second video with a message to kids: Eating healthy is cool.

Anna Lloyd, 22, said her 60-second Internet video "Fresh Grown," features five children rapping and dancing at a grocery store and at the Pepper Place Farmers' Market, both in Birmingham.

The pint-size rappers, surrounded by rows of carrots, tomatoes and strawberries, sing the lyrics "I like fresh grown fruits and vegetables."…

" I wanted a video that would make healthy foods cool, and that's where the idea for a hip-hop video came from."

Is milk from grass-fed cows more heart-healthy?

(Reuters Health) If milk does the heart good, it might do the heart better if it comes from dairy cows grazed on grass instead of on feedlots, according to a new study.

Earlier experiments have shown that cows on a diet of fresh grass produce milk with five times as much of an unsaturated fat called conjugated linoleic acid (CLA) than do cows fed processed grains. Studies in animals have suggested that CLAs can protect the heart, and help in weight loss.

Hannia Campos of the Harvard School of Public Health in Boston and her colleagues found, in a study of 4,000 people, that people with the highest concentrations of CLAs -- the top fifth among all participants -- had a 36 percent lower risk of heart attack compared to those with the lowest concentrations.

Dieting Alone May Not Help Stave Off Type 2 Diabetes; Muscle Mass, Strength Important

(Science Daily) Sarcopenia -- low skeletal muscle mass and strength -- is often found in obese people and older adults; it has been hypothesized that sarcopenia puts individuals at risk for developing Type 2 diabetes…

[Now, researchers have] found that sarcopenia was associated with insulin resistance in both obese and non-obese individuals. It was also associated with high blood-sugar levels in obese people but not in thin people. These associations were stronger in people under age 60, in whom sarcopenia was associated with high levels of blood sugar in both obese and thin people, and with diabetes in obese individuals.

Dieting to be thin is on its own not enough to stave off diabetes. It is also important to be fit and, in particular, to have good muscle mass and strength, researchers say.

Touch may speed healing in older patients

(UPI) Osteopathic manipulative medicine -- increasing muscle motion -- was linked to faster healing of older pneumonia patients, U.S. researchers found.

The randomized, controlled clinical trial at seven sites in five states … found pneumonia patients receiving conventional care alone stayed in the hospital one day more than pneumonia patients additionally receiving osteopathic manipulative medicine.

Osteopathic manipulative medicine is a drug-free form of hands-on care focused on increasing muscle motion, explained a study investigator, Kari Hortos.

Little-Known Mouth Fluid May Lead to Test for Gum Disease

(Science Daily) A little-known fluid produced in tiny amounts in the gums, those tough pink tissues that hold the teeth in place, has become a hot topic for scientists trying to develop an early, non-invasive test for gum disease, the No. 1 cause of tooth loss in adults. It's not saliva, a quart of which people produce each day, but gingival crevicular fluid (GCF), produced at the rate of millionths of a quart per tooth…

The findings advance efforts to develop an early test for gum disease, [researchers] suggest.

Potential New Source of Stem Cells for Heart Repair

(HealthDay News) Stem cells from the amniotic sac that surrounds a fetus may someday be used to repair damage caused by a heart attack, Japanese researchers report.

The work, so far only conducted in animals, raises the possibility of a non-controversial source of stem cells to treat not only heart disease but also many other conditions, said Dr. Shunichiro Miyoshi…

"I believe these cells may be utilized in the treatment of autoimmune diseases such as SLA [systemic lupus erythematosus] and rheumatoid arthritis," Miyoshi said. The amniotic sac is typically discarded after childbirth.

Putting New Medical Guidelines Into Practice Often Difficult

(HealthDay News) After taking part in a face-to-face program designed to review current research and guidelines, doctors made small improvements in the way they prescribed medicine for patients with high blood pressure, a new study reports.

"Ensuring that important clinical trial findings are reflected in the practices of community physicians remains a substantial challenge," the authors of the study wrote. Research indicates that many recommendations "diffuse into widespread community use only slowly and then incompletely. This failure to put scientific findings into practice not only compromises societal return on clinical trial investment but also weakens the scientific basis of clinical care."

Gratitude boosts romantic relationships

(UPI) Kind gestures can cement a romantic relationship -- but only if a partner expresses gratitude, U.S. researchers suggest…

The researchers tracked 65 couples in a satisfying and committed relationship for day-to-day fluctuations in relationship satisfaction and connection.

The study … found the positive impact on the relationship from kind gestures was noticed even the day after the feeling of gratitude was expressed.

However, if the partner feels indebtedness -- a need to repay kind gestures -- such acts may not yield benefits, the researchers said.

Stress Less with This Kind of Tea

(RealAge.com) Next time you're feeling frazzled, cozy up to a nice warm cup of chamomile tea.

In a small study of people with anxiety, stress symptoms dropped by about 50 percent when German chamomile (Matricaria recutita) was taken daily for 8 weeks…

Researchers suspect that the flavonoids in chamomile could have something to do with the soothing effects. Or it could be that compounds in chamomile bind to the same receptors as antianxiety medications do. Chamomile may even affect the way certain brain chemicals act on nerves. Feeling stressed? Grab a cup of chamomile tea and double it up with one of these other soothers:

Brief Exercise Reduces Impact of Stress on Cell Aging, Study Shows

(Science Daily) Exercise can buffer the effects of stress-induced cell aging, according to new research from UCSF that revealed actual benefits of physical activity at the cellular level.

The scientists learned that vigorous physical activity as brief as 42 minutes over a 3-day period, similar to federally recommended levels, can protect individuals from the effects of stress by reducing its impact on telomere length. Telomeres (pronounced TEEL-oh-meres) are tiny pieces of DNA that promote genetic stability and act as protective sheaths by keeping chromosomes from unraveling, much like plastic tips at the ends of shoelaces.

A growing body of research suggests that short telomeres are linked to a range of health problems, including coronary heart disease and diabetes, as well as early death.

Fit People Release More Fat-Burning Molecules During Exercise

(HealthDay News) A new study provides tantalizing clues about how exercise helps ward off heart disease and other ills: Fit people have more fat-burning molecules in their blood than less fit people after exercise.

And the very fittest are even more efficient, on a biochemical level, at generating fat-burning molecules that break down and burn up fats and sugars, the study reports.

A better understanding of these fat-burning molecules, called metabolites, may not only boost athletic performance, but help prevent or treat chronic illnesses such as type 2 diabetes and heart disease by correcting metabolite deficiencies, the researchers said.

A Healthier Burger with This Spice

(RealAge.com) Cooking meat at high temperatures -- a la flame grilling -- can create cancer-causing substances. But here's a spice that counters it: rosemary.

Yep, mixing some rosemary into your burgers may make them not only tastier but safer and healthier, too. In a study, adding rosemary extract to beef patties before grilling slashed the production of harmful high-heat compounds by up to 90 percent.

The cancer-causing substances created by high-heat grilling are called heterocyclic amines (HCAs). They form when amino acids and creatine react together under high temps -- and research suggests these compounds could up the risk of certain cancers, such as stomach cancer. In addition to adding rosemary to grilled meats, you can dial down the HCAs by cooking at lower temperatures and frequently turning meats on the grill. (Check out the YOU Docs' blog for five great ways to cut down on HCA production.)…

Here are eight more ideas on how to make grilled food better for you.

Toothbrushing May Stave Off Heart Woes

(HealthDay News) Here's another reason to brush your teeth regularly: People who don't perform this essential of oral hygiene seem to have a greater risk of heart disease compared to their more diligent peers.

"We were surprised to find a relationship between toothbrushing frequency and both cardiovascular disease and inflammatory markers in the blood," said Richard Watt, co-author of a study published this week in the BMJ.

"We have not established a causal relationship, however. More research is needed to test if improving patients' oral hygiene to reduce their gum inflammation has an effect on cardiovascular disease risk."…

Periodontal disease has been associated with a 19 percent increase in the risk of heart disease. That number leaps to 44 percent in people under the age of 65, according to the study.

The most likely culprit is the inflammation associated with gum disease, which can go system-wide and contribute to plaque build-up in the arteries.

[T]he new study … consisted of a number of different groups: criminal offenders, who had been diagnosed as having antisocial personality disorder with highly psychopathic tendencies, patients with damage to the frontal lobes of the brain, patients with damage to other areas of the brain, and healthy control subjects. The pattern of impairments in the psychopathic participants showed a remarkable resemblance to those in the participants with frontal lobe damage, suggesting that an underlying cause of the behavioural disturbances observed in psychopathy may be dysfunction in the frontal lobes.

Herbs, supplements often sold deceptively: U.S. report

(Reuters) Sellers of ginseng, echinacea and other herbal and dietary supplements often cross the line in marketing their products, going as far as telling consumers the pills can cure cancer or replace prescription medications, a U.S. government probe found.

In an undercover probe, investigators at the Government Accountability Office also found that labels for some supplements claim to prevent or cure ailments like diabetes or heart disease -- a clear violation of U.S. law…

The GAO, which conducts investigations for Congress, also said it found trace amounts of potentially harmful contaminants such as lead and arsenic, but at levels that do not exceed federal guidelines.

Findings of pesticides, however, did exceed the FDA's advisory levels, the GAO said, and 16 of 40 supplements tested would violate the FDA's tolerance.

15 best age-erasing superfoods

The latest science shows the muscle-building, brain-enhancing, wrinkle-erasing, heart-strengthening, bone-protecting, immunity-boosting, and inflammation-fighting foods you should be eating every day.

Almonds
These energy-rich snacks lower bad cholesterol, thanks to plant sterols, and benefit diabetics by lowering blood sugar…

Flaxseeds
Rich in protein and fiber, these little seeds offer a payload of omega-3 fatty acids, which erase spots and iron out fine lines in the skin…

Tomatoes
There are two things you need to know about tomatoes: red are the best, because they’re packed with more of the antioxidant lycopene; and processed tomatoes are just as potent as fresh ones, because it’s easier for the body to absorb the lycopene…

Rosemary
The carnosic acid found in this spice has been shown to reduce stroke risk in mice by 40 percent…

Dried plums
Also known as prunes, these dark shrivelers are rich in copper and boron, both of which can help prevent osteoporosis…

Whole grains
Whole grains — oatmeal, wheat flour, barley, brown rice — are high in fiber, which calms inflamed tissues while keeping the heart strong, the colon healthy, and the brain fueled. Whole grains can be loaded with carbs, but the release of those sugars is slowed by the fiber…

Yogurt
Various cultures claim yogurt as their own creation, but the 2,000-year-old food’s health benefits are not disputed: Fermentation spawns hundreds of millions of probiotic organisms that serve as reinforcements to the battalions of beneficial bacteria in your body…

Avocado
Chock full of monounsaturated fat, avocados deliver a double-barreled blast to LDL cholesterol (the bad kind). They are also rich in folate, a water-soluble B vitamin that helps lower the levels of homocysteine, an amino acid that can hinder the flow of blood through blood vessels. Eat a 1/4 cup twice a week, says [dietitian Sari] Greaves.

Walnuts
Richer in heart-healthy omega-3s than salmon, loaded with more anti-inflammatory polyphenols than red wine, and packing half as much muscle-building protein as chicken, the walnut sounds like a Frankenfood, but it grows on trees…

Turmeric
Curcumin, the polyphenol that gives turmeric its tang and yellow hue, has anti-cancer properties, anti-inflammatory effects, and tumor-fighting activities known in nutrition-speak as anti-angiogenesis. Researchers at UCLA have also found that it helps deter the accumulation of amyloid plaques in the brain, tiny blockages that may cause Alzheimer’s disease. Turmeric’s prevalence in India, the researchers suggest, may help explain why so few of the country’s senior citizens have the disease…

Black beans
People who eat one 3-ounce serving of black beans a day decrease their risk of heart attack by 38 percent, according to a study…

Apples
An apple a day reduces swelling of all kinds, thanks to quercetin, a flavonoid also found in the skin of red onions. Quercetin reduces the risk of allergies, heart attack, Alzheimer’s, Parkinson’s, and prostate and lung cancers. If given the choice, opt for Red Delicious. They contain the most inflammation-fighting antioxidants.

Leeks
“Leeks can support sexual functioning and reduce the risk of prostate cancer,” says Michael Dansinger, M.D…

Mushrooms
Delicious when added to brown rice, reiki, shiitake, and maitake mushrooms are rich in the antioxidant ergothioneine, which protects cells from abnormal growth and replication…

Figs
Packed with potassium, manganese, and antioxidants, this fruit also helps support proper pH levels in the body, making it more difficult for pathogens to invade, says [trainer Gunnar] Petersen. Plus, the fiber in figs can lower insulin and blood-sugar levels, reducing the risk of diabetes and metabolic syndrome. Select figs with dark skins (they contain more nutrients) and eat them alone or add them to trail mix.

Surgery, Stenting Fare Equally Well in Preventing Stroke

(HealthDay News) The latest major trial pitting invasive surgery against less invasive stenting to help prevent stroke shows that each is a safe, effective option…

After a median follow-up of 2.5 years, the team found no significant difference in rates of stroke, heart attack or death for patients receiving surgery versus stents. Overall, 7.2 percent of patients receiving stents went on to experience stroke, heart attack or death, compared to 6.8 percent of those undergoing the artery-clearing surgery.

The study found "excellent safety and long-term results for patients with warning signs for stroke as well as for patients without such warning signs," the study's national principal investigator, Dr. Thomas G. Brott … said in a Mayo news release.

Discovery May Lead to Safer Drinking Water, Cheaper Medicine

(Science Daily) A discovery that may pave the way to helping reduce health hazards such as E. coli in water could also make chemicals and drugs such as insulin cheaper to produce and their production more environmentally friendly.

By creating a three-dimensional model, [researchers] discovered exactly how the AceK protein acts as a switch in some bacteria to bypass the energy-producing cycle that allows bacteria like E. coli and salmonella to go into a survival mode and adapt to low-nutrient environments, such as water…

The discovery opens the door for scientists to identify a molecule that can keep the bypass switch from turning on so bacteria will die in water…

Conversely, discovering a molecule to keep the bypass switch turned on could produce a supply of the bacteria biotechnology companies use to produce compounds, such as insulin. Instead of using glucose in the fermenting process, companies could use less nutritional and cheaper acetate.

The cost difference would be tremendous and the process would produce less carbon dioxide making the process much more environmentally friendly.

Washington, D.C., Tops List of Healthiest U.S. Cities

(HealthDay News) Which U.S. city is the healthiest and fittest? According to the American College of Sports Medicine, bragging rights this year go to Washington, D.C.

The distinction headlined the group's annual report card on the well-being of the nation's largest urban areas. Labeled the American Fitness Index, the analysis ranks U.S. cities in terms of chronic disease prevalence as well as the degree to which heavily populated areas take steps to promote preventive health behaviors, ensure access to health care and support physical activity.

The index "not only measures the state of health and fitness in our nation's largest communities but evaluates the infrastructure, community assets, policies and opportunities which encourage residents to live a healthy and fit lifestyle," Walt Thompson, chairman of the American Fitness Index advisory board, said in a news release from the college…

Most of the top 10 cities are in the western part of the country. Following Washington, D.C., in order, are: Boston; Minneapolis-St. Paul; Seattle; Portland, Ore.; Denver; Sacramento, Calif.; San Francisco; Hartford, Conn.; and Austin, Texas.

The country's three biggest cities were neither the best nor worst performers, with New York City coming in 21st, Chicago ranking 33rd and Los Angeles, 38th.

Thompson and his colleagues noted a variety of factors that appeared to influence the health and fitness of urban dwellers. Being unemployed, they said, appeared to increase the risk for heart disease, and being better educated increased the likelihood of being active and in good or excellent health.

Being poor or disabled or living in an area prone to violent crime were also linked to a greater risk for having a variety of health concerns, including smoking, obesity, diabetes, and heart disease.

What's More Important in the Obesity Battle – Physical Activity or Medical Treatment?

(Science Daily) Experts disagree in the British Medical Journal about the best way to tackle the obesity crisis. While Professor Louise Baur and colleagues from the Children's Hospital at Westmead and the University of Sydney in Australia acknowledge that "physical inactivity is a major contributor to the global burden of disease," they says that it would be wrong to only focus on this and ignore the problem of obesity.

Baur and colleagues argue that physical inactivity is just one marker and that there is substantial evidence that unhealthy diets low in fibre and high in sugar and large portion size are also responsible for obesity and the diseases associated with it.
