Recognizing other people's emotions based on their facial expressions is a challenge for many people who have an autism spectrum disorder particularly children.
The physician Joseph Black first recognized magnesium as an element in 1755 but even before Black's time physicians were recommending the magnesium carbonate magnesia alba for people with an upset stomach.
As a supplement magnesium is touted to prevent hearing loss kidney stones and migraine headaches. Magnesium supplements are claimed also to improve athletic performance
and treat sleep troubles including restless leg syndrome and insomnia. Low magnesium levels have been linked to osteoporosis anxiety irritability depression and attention deficit hyperactivity disorder (ADHD.
Doctors sometimes recommend magnesium supplements to treat people with high blood pressure preeclampsia eclampsia heart attacks premenstrual syndrome (PMS) irregular heartbeat or an unhealthy ratio of HDL (high density-lipoprotein lipoprotein) cholesterol to LDL (low-density
lipoprotein) cholesterol. Some people with certain chronic conditions including diabetes multiple sclerosis fibromyalgia and chronic fatigue syndrome use magnesium supplements to control symptoms.
Magnesium is recommended occasionally to ease altitude sickness hay fever Lyme disease asthma and chronic obstructive pulmonary disease (COPD. Magnesium applied directly to the skin is said to treat skin infections
and speed up wound healing. Magnesium has also been touted to ease muscle cramps sensitivity to loud noises and kidney stones.
Many Americans do not get enough magnesium according to the National institutes of health. But some groups of people who have certain diseases
or conditions are even more likely to have low magnesium levels. Heavy drinking and alcoholism can result in chronically low magnesium levels
and gastrointestinal conditions such as Crohn's disease and celiac disease can also deplete magnesium levels. Older adults tend to have lower magnesium levels than young adults.
This happens in part because the gut becomes less efficient at absorbing magnesium and the kidneys become less efficient at retaining magnesium with age.
Type 2 diabetes can cause the kidneys to excrete too much magnesium and in turn lead to a magnesium deficit.
And some medications such as diuretics the heart drug digoxin and penicillamine (used for rheumatoid arthritis) can all interfere with magnesium in the body.
but a full-blown magnesium deficiency can cause nausea fatigue and weakness. Severe magnesium deficiency may cause numbness tingling muscle contractions seizures abnormal heart rhythm and personality changes.
Severely low magnesium can also result in a heart attack respiratory arrest and death. While magnesium supplements can certainly treat a magnesium deficiency studies also show getting more magnesium than the bare minimum may help certain conditions.
Several long-term studies have found a correlation between high magnesium levels and a lower risk of heart disease sudden cardiac death and ischemic heart disease according to the National institutes of health's Office of Dietary Supplements.
However high blood pressure can fall within a range of 20 mmhg: from 140/90 mmhg to 160/100 mmhg.
and type 2 diabetes studies have found but exactly how the two are linked is still unclear.
Both situations may also be true where diabetes leads to low magnesium and in turn low magnesium worsens diabetes according to the NIH.
A small number of studies show getting more magnesium may increase bone mineral density in elderly women
or treating osteoporosis. Guidelines from the American Headache Society and the American Academy of Neurology say magnesium is probably effective for migraine prevention.
However the guidelines recommend the nutritional supplement butterbur over magnesium to prevent migraines. The National Library of Medicine and the NIH determined that magnesium may help people with chronic fatigue syndrome and pain from fibromyalgia.
Scientific evidence also indicates that magnesium may help PMS high cholesterol kidney stones hearing loss asthma attacks and chronic obstructive pulmonary disease (COPD.
There are not enough studies to determine whether magnesium supplements could help anxiety ADHD hay fever Lyme disease or multiple sclerosis according to the NIH.
Studies are less promising on magnesium's ability to boost athletic performance. Magnesium is one of the seven major minerals that the body needs in relatively large amounts (Calcium potassium sodium chloride potassium
and phosphorus are the others). But too much of one major mineral can lead to a deficiency in another and excessive magnesium can in turn cause a deficiency in calcium.
Symptoms of toxic magnesium levels can range from upset stomach and diarrhea to more serious symptoms of vomiting confusion slowed heart rate and dangerously low blood pressure.
Severe magnesium overdoses can lead to problems breathing coma irregular heartbeat and even death. Magnesium supplements can interact with several drugs.
Similarly magnesium can interfere with some osteoporosis drugs if the doses are taken too close together. Magnesium can also interfere with some thyroid medications.
Magnesium can worsen side effects of some blood pressure medications and increase the potency of some diabetes medicines.

#Oral Allergy Syndrome: 6 Ways to Avoid an Itchy, Tingling Mouth It's not unusual for a person with seasonal allergies to have an itchy nose and itchy eyes.
But it may seem surprising that some hay-fever sufferers get an itchy feeling in their mouths throats
and lips when they start to eat certain foods. This condition is known as oral allergy syndrome (OAS)
or pollen-associated food allergy syndrome and it's the most common form of food allergy in adults.
It occurs because proteins found in some fresh fruits and vegetables are similar to allergy-causing proteins found in pollens such as ragweed birch mugwort and grasses.
Not long after some people with seasonal allergies eat uncooked fruits and raw vegetables as well as some nuts and spices these people's immune systems recognize a similarity between the food and pollen's proteins.
This is called cross reactivity. The thinking in the field is that the pollen allergy is the driver behind the immune response to the food said Dr. Wayne Shreffler director of the Food Allergy Center at Massgeneral Hospital for Children in Boston.
Here are his tips for people with hay fever who may experience oral allergy syndrome. Know your worst foods.
Shreffler said apples peaches plums cherries nectarines hazelnuts almonds and carrots are the most common food culprits of oral allergy symptoms that he sees in his Boston allergy clinic.
He noted that apples are a common offender for people who are allergic to birch pollen as well as foods such as celery pears
and other raw fruits containing pits because these fruits and vegetables are botanically close to birch.
or two foods on the list that might cause oral symptoms in some individuals with birch pollen allergies.
And people with grass pollen allergies might be bothered by tomatoes melons and oranges. Be aware of common symptoms.
Realize that some hay fever sufferers are affected not. OAS is pretty common in people with seasonal allergies Shreffler told Live Science.
We really don't know why it affects some people with pollen allergies and not others he added.
For some people symptoms might occur only during their pollen allergy season and they might be able to eat the food at other times of the year without any reactions.
But for others the offending food can trigger symptoms year-round whether it's pollen season or not.
and take an antihistamine to relieve the itchiness Shreffler advised. 8 Strange Signs You're Having an Allergic reaction Try other forms of the food.
Someone with a birch pollen allergy might get oral allergy symptoms from a fresh apple
That's because the food's allergy-causing protein is broken easily down by cooking or processing.
Oral allergy syndrome can occur in kids as young as 3 or 4 but people can also develop the sensitivity for the first time as adults.

#Cancer-Fighting Diet: 6 Tips to Reduce Your Risk Following six diet guidelines can reduce your cancer risk researchers say.
The advice is a combination of what foods to limit or avoid and which ones to eat.
and help consumers avoid the cancer-causing substances found in animal products. PCRM's recommendations are similar to those offered by cancer research organizations such as the American Cancer Society although arguably more extreme in terms of
what they say to avoid. It's never a bad idea to cut back on red meat
or alcohol as the PCRM recommends said Colleen Doyle a registered dietician and director for nutrition and physical activity for the American Cancer Society.
or vegetarian to significantly reduce your cancer risk she added. The recommendations 1. Eat more fruits
and vegetables especially leafy greens to help reduce overall cancer risk. Most doctors agree. It is an incontrovertible fact that a plant-based diet lowers your risk of cancer
and heart disease said Dr. Paul Talalay a distinguished service professor at Johns hopkins university in Baltimore who was involved not in this study.
The reason fruits and vegetables help lower cancer risk is that they contain protective compounds such as the phytochemicals that Talalay discovered in broccoli in the 1990s that reduce the risk of several cancers
and as reported this June the toxic effects of the pollutant benzene. 2. Eat soy products to reduce both the risk and recurrence of breast cancer.
Soy products such as edamame tempeh and tofu also have protective properties and if substituted for red meat can help reduce exposure to fats
and other chemicals that promote cancer and heart disease. 3. Limit or avoid dairy products to reduce the risk of prostate cancer.
Studies have linked dairy to prostate cancer but the culprit might be calcium. Yet other studies suggest that consuming dairy products might prevent colorectal cancer.
Dolye said men should consider limiting dairy if they have a family history of prostate cancer. 4. Limit
or avoid alcohol to reduce the risk of cancers of the mouth pharynx larynx esophagus colon rectum and breast.
The PCRM reports that one drink per week increases the risk of mouth pharynx and larynx cancers by 24 percent;
two to three drinks per day increase the risk of colorectal cancer by 21 percent.
As with the dairy recommendation the dangers depend on which studies you read. Mouth pharynx and larynx cancers are rare in nonsmokers
so a 24-percent risk increase isn't something to fret over. Also a drink a day seems to promote heart health.
The American Cancer Society recommends that people limit their alcohol intake to no more than two drinks per day for men and one per day for women (in part because of women's smaller average body size.
5. Avoid red and processed meats to reduce the risk of cancers of the colon and rectum.
Following this advice may help prevent heart disease stroke and diabetes. Large studies from the Harvard School of Public health revealed that regular consumption of red meat particularly processed meats such as sausages
and cold cuts will shorten your life. This news doesn't need to ruin your summer cookout plans.
and family history. 6. Avoid grilled fried and broiled meats to reduce the risk of cancers of the colon rectum breast prostate kidney and pancreas.
The reason is that cancer-causing chemicals called heterocyclic amines (HCAS) are created when creatine and amino acids in skeletal muscle aka meat are cooked at high temperatures.
Cancer risk reduction doesn't guarantee cancer avoidance. According to the World health organization up to 30 percent of all cancers might be caused by a poor diet.
The rest are attributed to smoking pollution and genetics which may affect you no matter what you eat.
and poison sumac#acts as an irritant causing an allergic rash on the skin. Its corrosive coating is the reason that cashew nuts are sold not in their shells like pistachios or peanuts.
or otherwise processed Enos said that those with a severe allergy to urshiol (i e. poison ivy) may not want to risk finding out
And like most nuts cashews are also a good source of Vitamin e and cancer-fighting phytochemicals.
Top 10 Cancer-Fighting Foods And in addition to the cashew's known nutritional benefits researchers have explored also the possibility of using the toxic oil found in the nut's shell as an antibiotic.
One study by researchers at University of California Berkeley found that anarcardic acid is effective at killing the bacteria that causes acne as well as that which causes tooth decay and the erosion of tooth enamel.
According to the researchers using cashew oil isn't an entirely new idea as the acid was used at one time in Brazil to treat leprosy.
Cashew nut oil as well as the leaves and bark of the cashew tree have also been used in traditional medicines in communities around the world to treat everything from toothaches to diabetes.
Oranges may additionally help reduce the risk of respiratory diseases certain cancers rheumatoid arthritis ulcers and kidney stones.
when drinking orange juice than when eating an orange warns the Centers for Disease Control. Here are the nutrition facts about oranges from the U s. Food and Drug Administration
Free radicals may lead to chronic conditions such as cancer and heart disease. Not only may oranges help reduce the risk of chronic conditions
but they may also boost a person's immunity when dealing with everyday viruses and infections like the common cold.
Lack of potassium can lead to arrhythmia an irregular heartbeat. According to one 2012 study people who consumed 4069 mg of potassium each day had a 49 percent lower risk of death from heart disease compared with those who consumed only about 1000 mg of potassium per day.
According to Flores the potassium found in oranges helps to lower blood pressure protecting against stroke. She noted another heart-related benefit pointing out that oranges are high in folate
which can help lower blood sugar levels in people with type 1 diabetes and improve blood sugar lipids
and insulin levels in people with type 2 diabetes. The American Diabetes Association lists oranges along with other citrus fruits as a superfood for people with diabetes.
Oranges are high in fiber which aids in digestion by keeping you regular. It is also good for weight loss.
Oranges are a low-fat nutrient-rich food with a low glycemic index which make it an ideal food to consume to protect against obesity
which can lead to other diseases such as heart disease cancer diabetes high blood pressure and stroke Flores told Live Science.
The Vitamin c in oranges is associated with a reduced risk of colon cancer due to preventing DNA mutations from taking place Flores said.
Studies have shown that about 10 to 15 percent of colon cancers have a mutation in a gene called BRAF.
and orange juice in the first two years of life may reduce the risk of childhood leukemia.
and could also lead to diarrhea. Though oranges are relatively low in calories eating several of the fruits in a day can add up
An excess of this nutrient may lead to diarrhea nausea vomiting heartburn bloating or cramps headaches insomnia or kidney stones.
Because they are a high-acid food oranges can contribute to heartburn especially for those who already suffer from heartburn regularly said Flores.
People with gastroesophageal reflux disease (GERD also called acid reflux disease) may experience heartburn or regurgitation if they eat too many oranges.
People who are taking beta-blockers should be careful not to consume too many oranges. These medicines increase potassium levels and if mixed with too many potassium-rich foods like oranges
Well-planned seed collections can also capture valuable traits like adaptations to drought and disease
and vegetables a day and a 2013 report from the U s. Centers for Disease Control and Prevention said that Americans eat less than three portions a day.
Similarly a condition called liver cirrhosis can cause lactation by disrupting the organ's normal hormone-metabolizing function.
For example a 2010 study published in the Canadian Medical Association Journal documented lactation in a man with a pituitary tumor.
and beta-carotene has been linked to anti-aging benefits cancer prevention and helping maintain good eyesight. While the orange variety is the most common in the United states sweet potatoes also come in white yellow pink and purple varieties.
It also means that sweet potatoes could be helpful in regulating blood sugar in people with TYPE II DIABETES (scientists are currently looking into it.
and are powerful disease-fighting antioxidants. While orange sweet potatoes contain more Vitamin a purple sweet potatoes are packed with the antioxidants cyanidin
which are useful for overall health as well as inflammatory disorders such as arthritis. Skin and hair Vitamin a can help protect against sun damage
which aids in maintaining a healthy digestive tract and helps keep you regular. Cancer prevention The NIH reports that some studies have suggested that beta-carotene may reduce the risk of breast cancer in premenopausal women ovarian cancer in postmenopausal women.
If eaten in moderation and prepared in a healthy way (that means not just indulging in sweet potato fries) sweet potatoes are a nutritious delicious food that should pose no significant health risks.
People with a history of kidney stones may want to avoid eating too many sweet potatoes as the vegetable contains oxalate
which contributes to the forming of calcium-oxalate kidney stones. Furthermore sweet potatoes contain potassium and phosphorus which is something that those with chronic kidney disease may want to avoid.
Given that sweet potatoes are in general very nutritious you don t need to cut them out of your diet
Though morning sickness doesn't usually begin for a few weeks some women may experience nausea or vomiting at this stage.
and avoid birth defects. Citrus foods are also naturally high in folate so a calcium-enriched orange juice is a great addition to any breakfast.

Nature Newsa plague of crop-eating caterpillars has struck Liberia and a second wave could spread across West Africa in the next few weeks,
Last week, a joint mission of 22 international health and veterinary experts returned from investigating the outbreak with more questions than answers about the virus's pathology and epidemiology.
and worrying, says Pierre Rollin, an Ebola expert at the US Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia,
as the avian influenza virus is thought to have done. And we still don't know what it might do to someone who is immunocompromised by HIV or by drugs,
Rollin adds. But there seems to be little threat to human health from the current form of the virus. It is destroyed by cooking,
if they have developed antibodies to the virus. The investigation into the Ebola Reston infections began after farmers in the Philippines reported high mortality rates in their pigs in 2008.
samples from 28 dead pigs were sent to the Plum Island Animal disease Center in New york, where researchers found evidence of the porcine reproductive and respiratory syndrome virus, also known as blue-ear pig disease,
This virulent, biosafety-level-4 pathogen requires special laboratory facilities, so the pig samples were rushed to the CDC labs in Atlanta for further analysis
. Despite the presence of other diseases in the samples including swine fever, and the porcine circovirus type II Rollin thinks that Ebola Reston is to blame for the pigs'deaths
Further pathology tests are due to begin in spring at the Australian Animal health Laboratory in Geelong, Victoria.
the infections resulted from contact with a reservoir of the virus, rather than spreading from animal to animal.
and the threat of infection could be reduced by moving fruit trees, where the bats roost, away from pig farms,
and doing them does not create some kind of greater harm. Lenton thinks that more such ideas,

Wheat genes could help fight fungal epidemics: Nature Newsas farmers around the world anxiously monitor the march of a deadly orange fungus across their wheat fields,
The results are welcome news as plant pathologists race to arm themselves against an ongoing epidemic of stem rust (P. graminis) caused by a recently emerged fungus called Ug99 (see'Wheat fungus spreads out of Africa'.
'The epidemic was isolated first in Uganda and has since spread eastwards into Iran. From there, pathologists believe wind currents may sweep Ug99 spores into India and, eventually, China.
Meanwhile, new types of stripe rust that can overcome the defences bred into commercial varieties have sparked a separate epidemic in the United states. It is amazing that we are still fighting this battle,
One problem is that breeders have relied traditionally on disease-resistance genes that are very effective
or work out how it confers resistance to fungal diseases. This week in Science, Beat Keller of the University of Zurich in Switzerland, Evans Lagudah of the Commonwealth Scientific and Industrial Research Organisation in Canberra
The team speculates that the proteins work by transporting metabolites that impede fungal growth to the site of the infection.
which requires a live host less time to establish an infection, the researchers say. Dubcovsky discovered the second fungi-fighting gene several years ago
he noticed that it was more resistant to rust infection than strains with normal protein content.
Neither Yr36 nor Lr34 can fully protect wheat against infection. In one study, infected wheat carrying only Lr34 had stripe rust covering 60%of its uppermost leaf
