The mushrooms therefore serve as a model organism for the study of the pathway involved in food spoilage.
The enzyme responsible for the mechanism of food spoilage is formed within eukaryotes (organisms that have a nucleus) as an inactive precursor during the developmental phase of an organism.

#Plant diversity in China vital for global food securitywith climate change threatening global food supplies new research claims the rich flora of China could be crucial to underpin food security in the future.
which helps sustain food production. Furthermore they can be utilised to improve the nutritional and marketing qualities of crops.
The research carried out by academics from the University of Birmingham represents a significant contribution to global research in plant genetic resources for food and agriculture particularly in the fight against the detrimental impacts of climate change on food security.
With more plant species than Europe and CWR of globally important food crops its position as a provider of plant genetic resources for crop improvement is crucial to us all globally.
say scientistswild species related to our crops which are crucial as potential future food resources have been identified by University of Birmingham scientists
which are needed for future crop variety development--could be conserved in the wild in order to secure future global food resources.
Climate change along with a steady rise in the human population is forecast to have a detrimental impact on crops that are grown for food.

#Global food trade may not meet all future demand, study indicatesas the world population continues to grow by about 1 billion people every 12 to 14 years
since the 1960s the global food supply may not meet escalating demand--particularly for agriculturally poor countries in arid to semiarid regions such as Africa's Sahel that already depend on imports for much of their food supply.
and the patterns of food trade that--until this analysis--have been studied minimally. Using production and trade data for agricultural food commodities collected by the United nations'Food and agriculture organization the study reconstructs the global food trade network in terms of food calories traded among countries.
We found that in the period between 1986 and 2009 the amount of food that is traded has doubled more than
and the global food network has become 50 percent more interconnected said Paolo D'Odorico a U. Va. professor of environmental sciences and the study's lead author.
International food trade now accounts for 23 percent of global food production much of that production moving from agriculturally rich countries to poorer ones.
D'Odorico noted that food production during that more than two-decade period increased by 50 percent providing an amount of food that would be feed sufficient to the global population with an increasing reliance on redistribution through trade.
The study provides a detailed analysis of the role of food trade in different regions of the world with maps showing areas of food self-sufficiency and trade dependency.
D'Odorico and his co-authors demonstrate that most of Africa and the Middle east are not self-sufficient
but trade has improved access to food in the middle East and in the Sahel region a vast populous semiarid region stretching across the central portion of the African continent that otherwise would not be able to produce enough food for its populations.
The investigators found however that trade has eradicated not food insufficiency in Sub-saharan africa and Central asia. Overall in the last two decades there has been an increase in the number of trade-dependent countries that reach sufficiency through their reliance on trade D'Odorico said.
Those countries may become more vulnerable in periods of food shortage such as happened during a food crises in 2008 and 2011
when the governments of some producing countries banned or limited food experts causing anxiety in many trade-dependent countries.
The food crises to which D'Odorico refers were caused by extreme climate events that brought drought conditions to several food-exporting nations including Russia Ukraine
and the United states. He found that 13 agricultural products--wheat soybean palm oil maize sugars and others--make up 80 percent of the world's diet and food trade.
He also found that China is greatly increasing its consumption of meat which already is changing land-use patterns in that country--meat production requires significantly more land area then crops.
and therefore are major exporters of food to agriculturally poor nations. However as populations grow
and the world food supply increasingly depends on this connection D'Odorico said. The food security for rapidly growing populations in the world increasingly is dependent on Trade in the future that trade may not always be reliable due to uncertainties in crop yields
and food price volatility resulting from climate change. Trade can redistribute food but it cannot necessarily increase its availability.

Martin Heller and Gregory Keoleian of U-M's Center for Sustainable Systems looked at the greenhouse gas emissions associated with the production of about 100 foods as well as the potential effects of shifting Americans to a diet
A paper by Heller and Keoleian titled Greenhouse gas emission estimates of U s. dietary choices and food loss is scheduled for online publication Sept. 5 in the Journal of Industrial Ecology.
because the USDA Dietary Guidelines Advisory Committee is for the first time considering food sustainability within the context of dietary recommendations he said.
However an appendix to the report lists the recommended average daily intake amounts of various foods including meat.
which Heller and Keoleian estimated using the USDA's Loss Adjusted Food Availability dataset as a proxy for per capita food consumption in the United states
In the United states in 2010 food production was responsible for about 8 percent of the nation's greenhouse gas emissions.
In general animal-based foods are responsible for more greenhouse gas emissions per pound than plant-based foods.
While beef accounts for only 4 percent by weight of the food available it contributes 36 percent of the associated greenhouse gases they conclude.
In their Journal of Industrial Ecology paper Heller and Keoleian also looked at wasted food

Results of this study are based on potassium from food not supplements. The researchers found: Researchers suggested that higher dietary potassium intake may be more beneficial before high blood pressure develops.
Our findings suggest that women need to eat more potassium-rich foods. You won't find high potassium in junk food.
Some foods high in potassium include white and sweet potatoes bananas and white beans. While increasing potassium intake is probably a good idea for most older women there are some people who have too much potassium in their blood
which can be dangerous to the heart. People should check with their doctor about how much potassium they should eat she said.

They suggest a 10-30%flat tax on nearly all packaged foods as well as foods served at most chain restaurants and by large cafeteria vendors.
This tax revenue would be used to offset the cost of subsidizing healthier foods such as fruits nuts vegetables fish beans

We believe our proposal of a food tax and subsidy system would be faster to implement than other approaches Rogoff added.
With a modest 10-30%tax on most packaged foods healthy foods such as fruits nuts and vegetables could be subsidized to cost pennies to consumers Mozaffarian said.
This would dramatically reshape the food supply help to reduce nutritional and health disparities amongst the poor and other disadvantaged Americans and potentially save billions of dollars in year in health care costs for diet-related diseases.

--if current trends continue--food production alone will reach if not exceed the global targets for total greenhouse gas (GHG) emissions in 2050.
The study's authors say we should all think carefully about the food we choose and its environmental impact.
and ensure there is enough food for all. As populations rise and global tastes shift towards meat-heavy Western diets increasing agricultural yields will not meet projected food demands of what is expected to be 9. 6 billion people--making it necessary to bring more land into cultivation.
This will come at a high price warn the authors as the deforestation will increase carbon emissions as well as biodiversity loss
They argue that current food demand trends must change through reducing waste and encouraging balanced diets.

and as humans globally eat more and more meat conversion from plants to food becomes less and less efficient driving agricultural expansion and land cover conversion
--but our choice of food is said Bajzelj. It is imperative to find ways to achieve global food security without expanding crop or pastureland.
Food production is a main driver of biodiversity loss and a large contributor to climate change and pollution so our food choices matter.
But even with the yield gaps closed projected food demand will still require additional land--so the impact on GHG emissions and biodiversity remains.
because the wasted food products have undergone already various transformations that require input of other resources especially energy said Bajzelj.
