#Which Comes First--Optimism Or Good health?(ISNS)--Boosting optimism defined as the general expectation that the future will be favorable could provide new ways to improve health some researchers believe.
But scientists remain unsure if optimism precedes health improvements or vice versa. Â Julia Boehm a psychologist at Harvard university and her colleagues performed
what she describes as one of the first studies to investigate a measurable link between psychological and physiological health.
To test the correlation researchers focused on the association between optimism and antioxidant concentration in the body.
Antioxidants can help combat disease by neutralizing unstable molecules called free radicals. Free radicals are produced in response to a number of environmental sources from cigarette smoke to pollution.
and can ultimately lead to disease. The body produces some antioxidants on its own but many come from the food we consume.
 This approach is a major strength of Boehm's research according to Hilary Tindle a physician at the University of Pittsburgh.
which discusses the relationship between optimism and health. Optimists classically self-report better diet choices but to my knowledge nobody has actually went
Even when adjusted for health behaviors the researchers found 3 to 7 percent higher levels of carotenoids in participants with higher optimism scores.
The findings published earlier this year in the journal Psychosomatic Medicine showed that smoking status
and potentially even improves health. Conversely good health may inspire a more optimistic attitude. Or the two qualities may reinforce each other.
Another recent study suggests that most people can't help but to think optimistically. This study was conducted by Ed O'brien a social psychologist at the University of Michigan in Ann arbor and published last month in the journal Psychological science.
 If optimism may lead to better health and people generally tend to think optimistically what does this mean for the connection between mental and physical health?
If we can establish that optimism comes before healthy states we might be able to intervene
the optimism or the good health. Â According to Tindle the question of causality is crucial. This research is critically important
and Lots of Confusion An enduring mantra among nutritionists from both a vegetarian and carnivorous perspective has been to eat more whole grains to reduce the risk of heart disease type 2 diabetes and colon cancer.
And with March touted as both National Colorectal Cancer Awareness Month and National Nutrition Month this mantra can be deafening.
A study published in January in the journal Public health Nutrition by researchers at Harvard School of Public health found that most whole grain labeling is confusing with the industry-supported Whole Grain stamp pointing to foods higher in sugar
A 1999 study led by David Ludwig now director of the New Balance Foundation Obesity Prevention Center at Boston Children's Hospital found that obese teenagers who ate a breakfast of instant oatmeal a highly processed

#Will poisoned Mice Solve Guam's Snake Problem? In a desperate bid to reduce Guam's population of poisonous brown tree snakes officials with the U s. Department of agriculture believe they've hit on a foolproof plan:
airdropping dead mice onto the Pacific island. It gets weirder: Before the airdrop the dead mice will have stuffed their bodies with Tylenol (acetaminophen)
which is toxic to the snakes according to the Guardian. Wait it gets weirder still. Each mouse will be fitted with a tiny parachute
so they'll be more likely to get snagged in trees where the snakes live.
That will also reduce the risk that the dead mice will poison other animals. The brown tree snake a native of Australia Papua new guinea
Though poisonous the invasive specie's venom isn't lethal to humans. But the snakes have wreaked havoc on the ecosystem of Guam decimating the island's native bird population.

#Worst Allergy Season Ever? Marlene Cimons writes forâ Climate Nexus a nonprofit that aims to tell the climate story in innovative ways that raise awareness of dispel misinformation about
This spring could be the most miserable one ever for those of us with allergies
  This promises a robust allergy season''said Leonard Bielory an allergy and immunology specialist with the Rutgers Center for Environmental Prediction in New jersey a state which suffered widespread destruction from Sandy.
and while the count is still low some allergy sufferers are showing comparatively severe symptoms''he added.
And pollen production is only part of the impact that global warming is going to have on allergies and asthma and our health overall.
and drought dust will worsen air pollution exacerbating asthma and other respiratory diseases. In other regions climate change will affect the insect population their stings
and bites can provoke fatal allergic reactions in sensitive individuals as well as the proliferation of such vines as poison ivy.
Midwestern and Western cities causing an increase in respiratory diseases. In short if you have allergies or asthma climate change is going to make you a lot sicker now and in the coming years.
 Allergic diseases are the sixth leading cause of chronic disease in the United states with an annual cost of $18 billion according to the federal Centers for Disease Control and Prevention.
More than 50 million Americans suffer from allergies annually. Â Â Â Â Â Â Â Â Â Â Â Asthma afflicts about 20 million Americans
and is rising around the world according to the CDC. Moreover some public health experts regard the global increase of asthma as an early health effect of climate change
and a harbinger of more health dangers to Come in fact one study published in the Journal of Allergy
and Clinical Immunology called climate change potentially the largest global threat to human health ever encountered''predicting more injury disease and death from natural disasters heat waves infections and widespread malnutrition as well as more allergic
and air-pollution illnesses and death. If you are lucky enough to be free from allergies don't make the mistake of dismissing them as nothing more than a minor annoyance.
Allergies can have a serious impact on the quality of life and in some circumstances a bee sting for example or if they trigger an asthma attack they can kill.
This is not just a matter of having a runny nose''said Jeffrey Demain director of the Allergy Asthma and Immunology Center of Alaska.
 Allergies affect the ability to go to work and go to school and they affect school and work performance.
They interfere with playing sports social opportunities how well you sleep your relationships and your overall general happiness.''
''On average someone with allergic disorders experiences a quality of life 35 percent less than the general population Demain said.
It really is quite dramatic''he said. Allergies occur when the body's immune system overreacts to a substance that generally doesn't bother other people.
The allergens can prompt sneezing coughing watery eyes and itching. In the years between 1970 and 2000 allergic rhinitis among Americans has risen from 10 percent to 30 percent
which correlates to similar increases in positive allergy skin-test results according to Bielory. Most experts believe the impact of climate change on allergic diseases will vary by region depending on latitude altitude rainfall and storms land-use patterns urbanization transportation and energy production.
Drought for example will contribute to increasing air pollution while heavy rain will wash the pollution away
but encourage the growth of mold. Bielory and his colleagues reporting in a 2011 study showed that the ragweed-pollen season has become longer in northern areas of the country in recent years
and points to climate change as the reason this is happening. Â We drew a line from Texas to Canada''he explained.
The pollen count duration remained the same in Texas but changed as you moved north.
Even though you are heading north to Canada the pollen started earlier and ended later and it should have been shortening.
The increased pollen is probably a way for the plant to adapt''said Demain who also is an associate clinical professor at the University of Washington.
More people are going to develop asthma and allergies and it's going to be severe.''''Stopping human activities that contribute to climate change might help future generations avoid these risks
but the rest of us like the plants themselves will have to adapt. We also can hope for a new medical breakthrough that will turn off the allergic response.

#Asparagus: Health Benefits, Risks (Stinky Pee) & Nutrition Facts In ancient times asparagus was renowned as an aphrodisiac.
Regardless of its powers to put you in the mood this succulent savory vegetable contains a stimulating blend of nutrients making this member of the lily family a fantastic food for your health.
Asparagus is balanced extremely well even among nutrient-rich vegetables. It is high in folic acid with a 5-ounce serving providing 60 percent of your recommended daily intake.
Asparagus is also a great source of potassium thiamin fiber magnesium calcium and vitamins K A B6 and C. Furthermore it contains the amino acid asparagine as well as chromium a trace mineral that helps insulin do its job transporting glucose.
or protect against certain cancers including bone breast lung and colon cancers. Asparagus is extremely low in calories at about 20 per serving has no fat
Here are the nutrition facts for asparagus according to the U s. Food and Drug Administration which regulates food labeling through the National Labeling and Education Act:
Heart health Asparagus is good for your ticker in a variety of ways. Its high level of B vitamins helps regulate the amino acid homocysteine too much
of which can be a serious risk factor in heart disease. Asparagus has more than 1 gram of soluble fiber per cup
which lowers the risk of heart disease. The vegetable s high levels of Vitamin k help maintain healthy blood clotting
Lastly asparagus has excellent anti-inflammatory effects and high levels of antioxidants both of which may help reduce the risk of heart disease.
Regulating blood sugar The B vitamins abundant in asparagus play a key role in metabolizing sugar and starches
Lowering the risk of type 2 diabetes As with heart disease risk of type 2 diabetes increases with excessive inflammation and oxidative stress.
Therefore asparagus impressive anti-inflammatory properties and high levels of antioxidants make it a good preventive food.
and improve Î-cell function also helps lower the risk of type 2 diabetes. Anti-aging benefits Free-radical busting antioxidants especially glutathioneare thought to slow the aging process.
and preventing kidney stones Asparagus can act as a natural diuretic due to its high amounts of the amino acid asparagine.
This can help rid the body of excess salt and fluid making it especially good for people suffering from edema and high blood pressure.
It also helps flush out toxins in kidneys and prevent kidney stones. Asparagus is high in fiber with 2 grams of insoluble fiber and 1 gram of soluble fiber per cup.
It also contains 4-5 grams of protein per cup. Both fiber and protein help keep the digestive process going helping you in maintaining cleansing regularity.
Decreasing birth defects It is essential for mothers-to-be to get enough folate which decreases the risk of neural-tube defects in fetuses.
What to Eat What Not to Eat Digestive health Asparagus is one of the few vegetables that contain inulin a unique carbohydrate associated with improved digestion.
There it nurtures bacteria known to improve nutrient absorption decrease allergies and lower the risk of colon cancer.
Cancer risk Antioxidants and anti-inflammatories which are found in great quantities in asparagus are associated typically with decreased risk of cancers.
It is possible to have an asparagus allergy in which case you should not eat it.
People who are allergic to other members of the lily family such as onions garlic and chives are more likely to be allergic to asparagus.
Symptoms include a runny nose hives trouble breathing and puffiness or swelling around the mouth and lips.
Health Benefits, Health Risks & Nutrition Facts Turns out that onions are nothing to cry over these flavorful bulbs are packed with nutrients.
which is linked to preventing cancer reducing the symptoms of bladder infections promoting prostate health and many other benefits.
They all are helpful in maintaining good health and have anticancer and antimicrobial properties. Partly because of their use in cooking around the world onions are among the most significant sources of antioxidants in the human diet.
Their high levels of antioxidants give onions their distinctive sweetness and aroma. These antioxidants and flavonoids may help promote heart health reduce inflammation
and reduce the risk of cancer in addition to a load of other good things. Onions are low in calories (45 per serving) very low in sodium
and contain no fat or cholesterol. Onions are healthy whether they re raw or cooked though raw onions have higher levels of organic sulfur compounds that provide many benefits.
Here are the nutrition facts for avocados according to the U s. Food and Drug Administration which regulates food labeling through the National Labeling and Education Act:
Heart health Onions encourage a healthy heart in many ways. The sulfur in onions can help lower high blood pressure lower bad cholesterol and increase good cholesterol.
It can also help to prevent blood clots stroke and your arteries from hardening. The sulfur acts as a natural blood thinner and prevents blood platelets from aggregating.
When platelets cluster the risk for heart attack or stroke increases significantly so onions blood-thinning properties can be a powerful aid against these heart problems.
which reduces the risk of heart attack and stroke. Anti-inflammatory Onions have been used to reduce inflammation for centuries.
Onions sulfurs are effective anti-inflammatory agents. For this reason onions are considered often a home remedy for asthmatic symptoms.
They can even reduce inflammation in blood vessels which reduces the risk of heart disease. The quercetin in onions can help with arthritis pain by easing swelling and joint stiffness.
Immune system Onions can promote a strong immune system by eliminating free radicals improving the effectiveness of Vitamin c in your body
and improving the absorption of minerals through probiotics which are promoted by the fiber in onions.
The quercetin in onions also reduces allergic reactions by stopping your body from producing histamines which are what make you sneeze cry
and itch if you re having an allergic reaction. Cancer Onions are high in quercetin a powerful anticancer agent.
In lower concentrations quercetin helps prevent cancer cells from growing by killing free radicals. In higher concentrations quercetin becomes toxic to cancer cells.
One recent study from The netherlands showed that people who ate onions absorbed twice as much quercetin as those who drank tea and more than three times as much quercetin as those who ate apples
which are other high-quercetin sources. Red onions are especially high in quercetin. Shallots and yellow onions are also good options.
Detoxification Onions have amino acids that are rich in organic sulfur. They initiate detoxification by forming the basis for glutathione helps the liver process toxins.
Digestion The fiber in onions promotes good digestion and helps keep you regular. Additionally onions contain a special type of soluble fiber called fructan
and ward off infections. The phytochemicals in onions that scavenge free radicals also reduces your risk of developing gastric ulcers.
Regulating blood sugar The chromium in onions assists in regulating blood sugar. The sulfur in onions helps lower blood sugar by triggering increased insulin production.
Women who ate onions frequently had a 20 percent lower risk of hip fracture than those who never ate onions.
Onions especially if consumed raw can worsen heartburn in people who suffer from chronic heartburn or gastric reflux disease.
Eating a large amount of green onions or rapidly increasing your consumption of green onions may interfere with blood thinning drugs.
It is also possible to have a food intolerance or allergy to onions. People with onion allergies may experience red itchy eyes
and rashes if an onion comes into contact with the skin. People with a food intolerance to onions may experience nausea vomiting and other gastric discomfort.
According to the National Onion Association: Onions probably originated in Central asia in modern-day Iran and Pakistan.
As early as the sixth century B c. a medical treatise the Charaka Sanhita celebrates the onion as medicine a diuretic good for digestion the heart the eyes and the joints.
Pedanius Dioscorides a Roman physician of Greek origin in first century A d. noted several medicinal uses of onions.
Pliny the Elder catalogued Roman beliefs that onions could cure poor vision induce sleep and heal mouth sores dog bites toothaches dysentery and lumbago.
Onions were prescribed to alleviate headaches snakebites and hair loss. They were used also as rent payments and wedding gifts.
Onions were used also in syrups as poultices as an ingredient in dyes and even as toys.
