Disposable optical test substrate for detecting harmful microbes

Mon, 20/11/2017 - 15:48
Harmful microbes and toxic micromolecules in food and drinking water can cause serious health problems around the world. Now a researcher has developed a disposable optical test substrate for use in microbial detection. The aim is to enable cost-effective detection of harmful microbes and toxins.

Apple allergens as an effective option for treating apple allergy

Mon, 20/11/2017 - 13:56
An apple allergy, which is related to birch pollen, is a very common phenomenon associated with birch pollen allergy – around 70% of those with a birch pollen allergy are also allergic to apples. In those affected, eating apples leads to swelling and rashes or itching in the mouth and gullet, as well as in the ear area, and even to blistering. Now researchers have shown in a Phase II trial that the apple allergen "Mal d 1" significantly reduces the symptoms of apple allergy and is therefore an effective and safe treatment option.

What grosses out a chimpanzee? The origins of disgust

Fri, 17/11/2017 - 15:38
Chimps show increased latencies to feed, and tendencies to maintain greater distances from possible contaminants and/or outright refusals to consume food in test conditions, hinting at the origins of disgust in humans.

When vegetables are closer in price to chips, people eat healthier

Thu, 16/11/2017 - 18:21
A new study determined that the difference in price of healthy foods compared to unhealthy foods plays a significant role in whether people have a healthy diet.

Genome of wheat ancestor sequenced

Wed, 15/11/2017 - 18:38
Sequencing the bread wheat genome has long been considered an almost insurmountable task, due to its enormous size and complexity. Now, scientists have come a step closer to solving the puzzle by sequencing the genome of a wild ancestor of bread wheat known as Aegilops tauschii, a type of goatgrass.

Gut microbes can protect against high blood pressure

Wed, 15/11/2017 - 18:08
Microbes living in your gut can help protect against the effects of a high-salt diet, according to a new study.

After cooking, biofortified corn and eggs retain nutrient needed to prevent blindness

Wed, 15/11/2017 - 18:08
Fortified and biofortified foods are at the forefront of efforts to combat vitamin A deficiency worldwide. But little is known about what influence processing may have on the retention of vitamin A precursors in these foods. Now scientists report that a high percentage of these healthful substances -- in some cases, almost all -- can survive cooking, depending on the preparation method. 

Organic farming can make an important contribution to world nutrition, research shows

Wed, 15/11/2017 - 14:21
A global conversion to organic farming can contribute to a profoundly sustainable food system, provided that it is combined with further measures, specifically with a one-third reduction of animal-based products in the human diet, less concentrated feed and less food waste, shows new research.

Tue, 14/11/2017 - 17:33
The occurrence of stem end rot (SER) during storage means major losses for mango fruit growers and suppliers. Promising new research explores sunlight's role in cultivating a beneficial mix of microorganisms that help mitigate SER.

How food poisoning bacteria Campylobacter uses other organisms as Trojan horse to infect new hosts

Tue, 14/11/2017 - 14:19
New research has shown how the food poisoning bacteria Campylobacter can multiply and spread inside micro-organisms called amoebae- which could lead to a better understanding of how bacteria survive and help efforts to prevent the spread of infection.

Eating regular variety of nuts associated with lower risk of heart disease

Tue, 14/11/2017 - 00:51
People who regularly eat nuts, including peanuts, walnuts and tree nuts, have a lower risk of developing cardiovascular disease or coronary heart disease compared to people who never or almost never eat nuts, according to a new study. The study is the largest to date looking at frequency of nut consumption in relation to incident cardiovascular disease.

Tomatoes with enhanced antioxidant properties created with genetic engineering

Fri, 10/11/2017 - 16:39
New research has identified a new strategy to simultaneously enhance health-promoting vitamin E by ~6-fold and double both provitamin A and lycopene contents in tomatoes, to significantly boost antioxidant properties.

Crunch time for food security

Fri, 10/11/2017 - 16:39

Climate-influenced changes in flowering, fruiting also affect bird abundance, activities

Thu, 09/11/2017 - 02:56
A new study has documented shifts in Hawaiian bird abundance, breeding and molting based on climate-related changes to native vegetation. Researchers with the US Forest Service's Pacific Southwest Research Station recently reviewed extensive climate, vegetation and bird data collected between 1976 and 1982 at a 40-acre monitoring site about 5 miles outside Hawai'i Volcanoes National Park on Hawai'i Island. The study is featured in this month's issue of Ecology.

'Golden' potato delivers bounty of vitamins A and E

An experimental 'golden' potato could hold the power to prevent disease and death in developing countries where residents rely heavily upon the starchy food for sustenance, new research suggests.

New 'sugar-glass' film uses viruses to kill harmful bacteria in food

Wed, 08/11/2017 - 15:21
With antibiotic resistance on the rise, bacterial contamination of food is becoming more problematic. Now in a study, scientists report that they have developed an antibacterial 'sugar-glass' coating in which viruses that destroy bacteria are embedded and are kept stable for up to three months. The coating could someday be used in the food packaging and processing industries to help prevent food-borne illnesses and deaths.
