Archaeologists discover bread that predates agriculture by 4,000 years

Mon, 16/07/2018 - 20:15
At an archaeological site in northeastern Jordan, researchers have discovered the charred remains of a flatbread baked by hunter-gatherers 14,400 years ago. It is the oldest direct evidence of bread found to date, predating the advent of agriculture by at least 4,000 years. The findings suggest that bread production based on wild cereals may have encouraged hunter-gatherers to cultivate cereals, and thus contributed to the agricultural revolution in the Neolithic period.

Allergy potential of strawberries and tomatoes depends on the variety

Fri, 13/07/2018 - 16:19
Strawberries and tomatoes are among the most widely consumed fruits and vegetables worldwide. However, many people are allergic to them, especially if they have been diagnosed with birch pollen allergy. A team has investigated which strawberry or tomato varieties contain fewer allergens than others and to what extent cultivation or preparation methods are involved.

Growing a dinosaur's dinner

Fri, 13/07/2018 - 16:19
Scientists have measured the nutritional value of herbivore dinosaurs' diet by growing their food in atmospheric conditions similar to those found roughly 150 million years ago.

Tree shrews can tolerate hot peppers: Mutation in pain receptor makes peppery plant palatable

Thu, 12/07/2018 - 19:16
Almost all mammals avoid eating chili peppers and other 'hot' foods, because of the pain they induce. But not the tree shrew, according to a new study. The researchers found that this close relative of primates is unaffected by the active ingredient in chili peppers due to a subtle mutation in the receptor that detects it.

5,300-year-old Iceman's last meal reveals remarkably high-fat diet

Thu, 12/07/2018 - 16:46
In 1991, German tourists discovered a human body that was later determined to be the oldest naturally preserved ice mummy, known as Otzi or the Iceman. Now, researchers who have conducted the first in-depth analysis of the Iceman's stomach contents offer a rare glimpse of our ancestor's ancient dietary habits. Among other things, their findings show that the Iceman's last meal was heavy on the fat.

New research could banish guilty feeling for consuming whole dairy products

Wed, 11/07/2018 - 23:27
Enjoying full-fat milk, yogurt, cheese and butter is unlikely to send people to an early grave, according to new research.

How a Mediterranean diet could reduce bone loss in osteoporosis

Wed, 11/07/2018 - 14:31
Eating a Mediterranean-type diet could reduce bone loss in people with osteoporosis -- according to new research. New findings show that sticking to a diet rich in fruit, vegetables, nuts, unrefined cereals, olive oil, and fish can reduce hip bone loss within just 12 months.

Livestock feed accurately predicts toxic chemicals in food

Tue, 10/07/2018 - 17:28
Scientists have tracked the presence of a class of synthetic flame retardants called polybrominated diphenyl ethers (PBDEs), which were once a popular additive to increase fire resistance in consumer products such as electronics, textiles, and plastics.

From corn to flake: Health-promoting phenolic acids lost during food processing

Tue, 10/07/2018 - 01:29
For many Americans, highly processed foods are on the menu for breakfast, lunch, and dinner. Even when the raw materials -- grains, for example -- are high in vitamins and health-promoting phenolic compounds, processing can rob the final product of these nutrients. Scientists reveal what happens to cancer-fighting phenolic acids in corn when it is processed into cornflakes.

National school food policies have potential to improve health now and later

Mon, 09/07/2018 - 15:11
Providing free fruits and vegetables and limiting sugary drinks in schools could have positive health effects in both the short- and long-term, finds a new Food-PRICE study.

Savory foods may promote healthy eating through effects on the brain

Fri, 06/07/2018 - 20:08
Researchers have found that consuming a broth rich in umami -- or savory taste -- can cause subtle changes in the brain that promote healthy eating behaviors and food choices, especially in women at risk of obesity.

In India, swapping crops could save water and improve nutrition

Wed, 04/07/2018 - 20:18
India will need to feed approximately 394 million more people by 2050. Meanwhile, many of its regions are chronically water-stressed, and nutrient deficiencies are widespread -- 30 percent of Indians or more are anemic. But a new study shares a brighter outlook: replacing some rice with less thirsty crops could dramatically reduce water demand in India, while also improving nutrition.

A diet rich in nuts improves sperm count and motility

Wed, 04/07/2018 - 16:20
The inclusion of nuts in a regular diet significantly improves the quality and function of human sperm, according to results of a randomized trial which measured conventional semen parameters and molecular changes over a 14-week study period. The findings, say the investigators, 'support a beneficial role for chronic nut consumption in sperm quality' and reflect a research need for further male-specific dietary recommendations.

New genomic regions associated to weight gain in Nelore cattle

Tue, 03/07/2018 - 16:28
A pioneering research project has identified genes potentially associated with functions such as growth and weight gain in the Nelore breed. These functions are key to beef production. The researchers pinpointed genomic regions that had changed owing to selection, referring to these as genomic signatures of selection.

Host plants tell insects when to grow longer wings and migrate

Mon, 02/07/2018 - 20:47
Scientists have discovered that the quality of the host rice plant determines whether the brown planthopper, a major pest on rice in Asia, grows short wings or long wings.

A new twist on how parasites invade host cells

Mon, 02/07/2018 - 16:11
Researchers have decoded the mechanisms used by the parasite Toxoplasma gondii to enter the cells of a host. Using high-resolution, high-speed imaging, they identified a unique process by which the parasite closes the 'entry door' it creates in order to enter and inhabit a host cell.

Mandatory labels reduce GMO food fears

Wed, 27/06/2018 - 21:05
As national regulators work to develop labeling standards for foods containing genetically modified ingredients, a researcher finds that consumer opposition to GMOs dropped significantly after Vermont adopted mandatory labels.

Dramatic change in way ancient diets are calculated

Wed, 27/06/2018 - 21:03
Knowing what extinct animals ate has long been determined by analyzing carbon isotopes locked inside fossil teeth. For two decades, a key isotope value in these equations has been assumed to be the same for all plant-eating mammals, but new research contradicts that assumption, revealing that the value changes with body size.

Your brain anatomy may play a role in determining your food choices

Our ability to exercise self-control is linked to our neurobiology.

Garden seed diet for threatened turtle doves has negative impact

Thu, 21/06/2018 - 15:13
New research into Britain's fastest declining bird species has found that young turtle doves raised on a diet of seeds foraged from non-cultivated arable plants rather than food provided in people's gardens are more likely to survive after fledging. Ecologists investigated the dietary habits of European turtle doves using DNA analysis of faecal samples and found significant associations between the body condition and the source of the bird's diet.
