#Scientists map food security, self-provision of major citieswealthy capital cities vary greatly in their dependence on the global food market.
The Australian capital Canberra produces the majority of its most common food in its regional hinterland
The Copenhagen hinterland produces less than half of the consumption of the most common foods. For the first time researchers have mapped the food systems of capital cities an essential insight for future food security

Dr Knapp says Both sexes on visited islands consume food distributed by tourists although male iguanas are more aggressive
when feeding and eat more provisioned food. Consequently they may be impacted more by provisioning with unnatural foods
which could explain the greater suite of significant physiological differences in males between populations. Iguanas on visited islands predominantly eat grapes that are provided by tour operators on a daily basis. The higher concentrations of glucose found in tourist-fed iguanas may be a result of being fed too many sugary fruits such as grapes.
Furthermore food provisioning by tourists on beaches has encouraged the iguanas to spend disproportionate amounts of time foraging in the area rather than further in the island resulting in higher levels of marine life being ingested.
and excessive reliance on tourists for food may prove problematic if food supplementation is discontinued for any reason.
Further plant community dynamics can be disrupted by changed feeding patterns in the iguanas. Dr Knapp says The complete restriction of feeding by tourists may not be a realistic option.
Instead wildlife managers could approach manufacturers of pelleted iguana foods and request specially-formulated food to mitigate the impact of unhealthy food.
Tour operators could offer or sell such pellets to their clients which would provide a more nutritionally balanced diet

The new research from the Universities of Leicester Sussex and Cambridge examines how locusts associate odours with nutritious or toxic food.
Locusts should consider toxic food'bad 'while they live alone but'good'when they are in a swarm
When we presented solitary locusts with an unfamiliar odour together with toxic food they assigned it an aversive('bad')value.
Desert locusts aggregate into swarms when they run out of food--the crowding is driven by hunger and competition for the last few plants in the desert.
And because they can no longer form aversive memories any food is now rewarding and they form the new'correct'appetitive memory with the odour.
The study recalls the work of Russian physiologist Ivan Pavlov who famously studied dogs salivating in anticipation of food.
Pavlov rang a bell every time he presented the dog with food. After a few'training sessions'ringing the bell alone was sufficient to make the dog salivate as it had come to associate the sound of the bell with getting food.
The scientists trained the locusts just like Pavlov trained his dog except that the unfamiliar smell replaces the bell in Pavlov's experiments:

And if you train solitary locusts with toxic food and vanilla they will also go to lemon.
Participants in the studies filled out detailed food questionnaires every two to four years. With each food questionnaire participants were asked to estimate how often they consumed nuts in a serving size of one ounce.
A typical small packet of peanuts from a vending machine contains one ounce. Sophisticated data analysis methods were used to rule out other factors that might have accounted for the mortality benefits.
In fact based on previous studies the US Food and Drug Administration concluded in 2003 that eating 1. 5 ounces per day of most nuts may reduce the risk of heart disease.

#You can have a food allergy, and eat it toohave food allergies? If you answered yes you know the best way to prevent a severe allergic reaction is to totally avoid the offending food.
But according to a presentation at the Annual Scientific Meeting of the American College of Allergy Asthma and Immunology (ACAAI) you may no longer have to avoid the food entirely.
Different parts of food may have said different allergenicity presenter Sami Bahna MD allergist and ACAAI past president.
For example someone with an egg allergy may be able to tolerate egg yolk but not the whites.
And someone with a fruit allergy may be allergic to the seeds but not the pulp.
not only can certain parts of food be safe to eat for some food allergy sufferers
Some sufferers might have to avoid several foods which can be difficult and cause malnutrition.
Some food sensitivities may also predict other food allergies. Different types of fruits and fish can often have substantial cross-reactivity meaning there may be several types that need to be avoided.
While many food allergic individuals find they can eat certain parts of food or substitutes this isn't a one size fits all approach said Dr. Bahna.
If you have a food allergy evaluation by a board-certified allergist can identify the exact foods that you should avoid
and the substitute foods that you can safely eat. Allergy skin testing or blood testing are good screening procedures for food allergy.
Allergists often confirm the suspected foods by performing oral food challenges. During this test patients are fed tiny amounts of the suspected allergy-causing food in increasing doses under strict supervision by an allergist.
Although there is no cure for food allergies at present some sufferers may outgrow their allergy over time.
Milk allergy is commonly outgrown in childhood while a peanut or shellfish allergy usually lasts for many years or for a lifetime.
Story Source: The above story is provided based on materials by American College of Allergy Asthma and Immunology (ACAAI.
It is also known as pollen-food syndrome since it is caused by cross-reacting allergens found in both pollen and raw produce.
Sufferers can often mistake oral allergy syndrome symptoms for food allergy said allergist David Rosenstreich MD ACAAI fellow and study author.
But it isn't a food allergy and often patients can eat that food when it is cooked.
For example an individual may have a reaction to a raw apple but not to apples baked in a pie.
#Buffet dish sequences may prompt healthier choicesevery day millions of people stand in line at all-you-can-to-eat buffet lines waiting to satiate their palates with the delicious foods on the line.
Most of these people however are unaware that food order biases what ends up on their plates:
the first food in line is taken the most and biases what else is taken. In fact this influence is so strong that in a recent study published In public Library of Science One Drs.
Plus when less healthy foods are served first individuals take 31%more total food items. Drs. Wansink and Hanks conducted their study at a conference where attendees were served a seven-item breakfast buffet.
In the dining area the food items were served on two separate tables just over 50 feet apart.
Unbeknownst to the attendees foods were arranged in opposite order on the two lines. On one line cheesy eggs fried potatoes bacon cinnamon rolls low-fat granola low-fat yogurt and fruit were served in that exact order.
Results from this experiment showed that the foods presented first biased which foods were selected by the attendees.
Specifically 86.4%of diners took fruit when it was offered first while 54.8%took fruit when it was offered last.
Of a person's plate 65.7%was filled with at least one of the first three foods in the line.
There was also an interesting correlation between the first food offered and subsequent selections. In the cheesy eggs first line selecting cheesy eggs was correlated strongly with taking potatoes and bacon.
This highlights the cultural association of eggs with bacon and/or potatoes where fruit is associated not generally with any specific food.
Like other behavioral biases the influence of food order can be leveraged to encourage selection and intake of healthier foods.
At your next dinner party or holiday event if you want your guests to make healthier choices put the healthier foods first to help them be slim by design.

and blue tits scout for food in the morning but only return to eat it in late afternoon to maximize their chances of evading predators in the day without starving to death overnight Oxford university research has found.
By moving 36 of these feeders around the forest throughout the day and recording the results the team showed that birds gathered information about new food sources during the morning
The researchers wanted to test the idea that instead of simply'idly waiting'until the afternoon birds were actively seeking out new sources of food to work out where their next meal was coming from.'
'Our results show that these birds display very different patterns of food discovery in the morning and afternoon;
very few new food sources were found during the afternoon whereas nearly every new food source that we put out during the morning was discovered quickly.
It supports the idea of an'early bird'strategy of scouting for food early on so that they can return to feast a couple of hours before dusk in preparation for a long winter's night.'

#Higher rates of diabetes, hypertension, heart disease, stroke in food desertthere is more to the cost of living in a food desert than higher prices for the few fruits
The nearest grocery stores are two to five miles away falling within the U s. Department of agriculture's federal designation of a food desert Stone said.
The federal agency defines a food desert as a census tract with a substantial share of residents who live in low-income areas that have low levels of access to a grocery store or healthy affordable food retail outlet.
The USDA's Economic Research Service estimates that 23.5 million people in the U s. live in food deserts in urban neighborhoods and rural towns without ready access to fresh healthy and affordable food.
Residents were given a written survey with questions about food shopping including a question that asked how their food purchases might change
and look at the kinds of foods they provided Stone said. One of the stores sold fresh fruits and vegetables while another one had a basket with a few apples
Selections of healthier foods were limited and what was available was more expensive than at a grocery store.
and would change what foods they purchased if a grocery store were located nearby Stone said. Residents also indicted a need not only for a grocery store but for nutritional education about healthy food particularly for men who tended to purchase fewer healthy foods than women.
Patients with non-celiac wheat sensitivity (NCWS) and other food sensitivities showed clinical laboratory and histological characteristics suggesting they may be suffering from a non-Ige-mediated food allergy according to the article Non-Celiac Wheat Sensitivity as an Allergic Condition:
Personal Experience and Narrative Review published online today in The American Journal of Gastroenterology. In this review lead author Antonio Carroccio M d. from the University of Palermo in Palermo Italy examines prior data regarding NCWS
Food allergies are divided typically into two areas: Ige mediated or non-Ige mediated. In Ige mediated food allergies people develop symptoms almost immediately after eating
and when blood and skin tests are carried out there is a positive marker. Non-Ige mediated food allergies including celiac disease primarily affect the GI mucosa (the innermost layer of the gastrointestinal tract)
and have delayed a onset of symptoms which can make it difficult to diagnosis. Dr. Carroccio and his colleagues reviewed data on 276 patients diagnosed with NCWS using a double-blind placebo-controlled wheat challenge.
The authors hypothesize that patients with NCWS may be suffering from non-Ige mediated food allergy.
