The process of glycosylation, where sugar molecules are attached to proteins, has long been of interest to scientists, particularly because certain sugar molecules are present in very high numbers in cancer cells. It now turns out that these sugar molecules are not only present, but actually aid the growth of the malignant cells.
The citrus flavor and aroma of grapefruit—already used in fruit juices, citrus-flavored beverages, and prestige perfumes and colognes—may be heading for a new use in battling mosquitoes, ticks, head lice and bedbugs thanks to a less expensive way of making large amounts of the once rare and pricey ingredient
For the first time, it has been shown that an intensively active lifestyle can “completely prevent” bad diets from impairing sexual function, says a Johns Hopkins University urology fellow. Put another way, a recent rat study offers strong evidence that erectile dysfunction (ED) is more than just a bedroom bother. It may be one’s own natural biomarker for coronary artery disease.
A magical hydrating beer that minimizes hangover has been brewed, Australian researchers say. By adding electrolytes, a natural body chemical and a common sports drink ingredient, the merry Aussies say they have minimized the dehydration side effects of the beverage.
The world’s most expensive coffee can cost $80 a cup, and scientists now are reporting development of the first way to verify authenticity of this crème de la crème, the beans of which come from the feces of a Southeast Asian animal called a palm civet.
Genetics may play a role in how people's taste receptors send signals, leading to a wide spectrum of taste preferences, according to Penn State food scientists. These varied, genetically influenced responses may mean that food and drink companies will need a range of artificial sweeteners to accommodate different consumer tastes.
Your morning cup of tea or coffee may be doing more than just perking you up before work. An international team of researchers led by Duke-NUS Graduate Medical School (Duke-NUS) and the Duke University School of Medicine suggest that increased caffeine intake may reduce fatty liver in people with non-alcoholic fatty liver disease (NAFLD).
A gene variant strongly associated with development of type 2 diabetes appears to interact with a Mediterranean diet pattern to prevent stroke, report researchers. Their results are a significant advance for nutrigenomics, the study of the linkages between nutrition and gene function and their impact on human health, particularly chronic disease risk.
When mice ate a diet of 25 percent extra sugar– the mouse equivalent of a healthy human diet plus three cans of soda daily– females died at twice the normal rate and males were a quarter less likely to hold territory and reproduce, according to a newly developed toxicity test.
Drinking two cups of hot chocolate a day may help older people keep their brains healthy and their thinking skills sharp, according to a new study. The study involved 60 people with an average age of 73 who did not have dementia and who drank two cups of hot cocoa per day for 30 days.
A sleepless night makes us more likely to reach for doughnuts or pizza than for whole grains and leafy green vegetables, suggests a new study that examines the brain regions that control food choices. The findings shed new light on the link between poor sleep and obesity.
Patients with celiac disease who had persistent intestine damage (identified with repeat biopsy) had a higher risk of lymphoma than patients whose intestines healed, according to a new study. The damage is due to a reaction to eating gluten, which is found in wheat, barley and rye.
Research suggests that we all smell different smells thanks to our genes. Scientists tested nearly 200 people for their sensitivity to ten different flavors that occur in food and have identified some of the genetic differences that determine an individual’s ability to smell various odors.
A new study suggests that mothers who breastfeed run a lower risk of developing Alzheimer’s, with longer periods of breastfeeding further reducing the risk. The report suggests that the link may be to do with certain biological effects of breastfeeding.
Two volunteers who participated in the first public frying of hamburger grown in a lab say that it had the texture of meat but was short of flavor because of the lack of fat. A research team in the Netherlands developed the burger, which was grown in a laboratory from stem cells of cattle.
Donna Heller thought she had cancer. But multiple visits to the doctor after a month with debilitating nausea and diarrhea didn't yield any answers. Convinced she was dying, she met with her lawyer to get her will in order. Then she saw a television report about an outbreak of cyclospora possibly linked to bagged salad mix.
A label that reads "gluten free" will now mean the same thing for all food, regardless of which kind you buy. After more than a six-year delay, the Food and Drug Administration has set a new standard for labels that will make shopping easier for consumers on gluten-restricted diets.
New research found that aging elicits changes in taste preferences and that such changes appear to be independent of taste nerve activity. The researchers investigated differences in fluid intake and taste nerve responses across different age groups of rats.
Federal health authorities say more than 275 people in seven states have now been sickened with an unidentified stomach bug. The Food and Drug Administration is investigating the cyclospora infections, which are often found in tropical or subtropical countries and have been linked to imported fresh produce in the past.
In older men, a natural antioxidant compound found in red grapes and other plants– called resveratrol– blocks many of the cardiovascular benefits of exercise, according to results from a recent research project. The research unusually suggests that eating a diet rich in antioxidants may actually counteract many of the health benefits of exercise.
A type of fungus coating much of the stored corn, wheat, rice and nuts in developing countries may be quietly worsening the AIDS epidemic, according to a new study. Kept in sacks piled in barns and warehouses, food stores in countries near the equator are contaminated by Aspergillus flavus and A. parasiticus, fungi that produce a toxic substance called aflatoxin.
Another reason to eat breakfast: Skipping it may increase your chances of a heart attack. A study of older men found those who regularly skipped breakfast had a 27 percent higher risk of a heart attack than those who ate a morning meal.
Eosinophilic esophagitis (EoE) is a food allergy-associated disease that affects children and adults and is caused by inflammation in response to trigger foods. Researchers have known that genetic mutations in the gene that encodes for thymic stromal lymphopoietin (TSLP) are highly associated with EoE in children. Now, researchers have identified one mechanism by which TSLP might contribute to the development of EoE.
Healthy snacks that promote a feeling of fullness (satiety) may reduce the amount of food intake at subsequent meals and limit overall food consumption, according to a presentation at the 2013 Institute of Food Technologists (IFT) Annual Meeting & Food Expo.
Parents who have been fretting over the low levels of arsenic found in apple juice can feel better about buying one of their kids' favorite drinks. The Food and Drug Administration is setting a new limit on the level of arsenic allowed in apple juice, after more than a year of public pressure from consumer groups worried about the contaminant's effects on children.
