Asparagine, found in foods such as meat, eggs, and dairy products, was until now considered non-essential because it is produced naturally by the body. Researchers have now found that the amino acid is essential for normal brain development.
Help yourself to some nuts this holiday season: Regular nut eaters were less likely to die of cancer or heart disease — in fact, were less likely to die of any cause — during a 30-year Harvard study.
The caffeine in a cup of coffee might help your small blood vessels work better, according to a new study showing that drinking a cup of caffeinated coffee significantly improved blood flow in participants' fingers.
Men with prostate cancer who ate a low-fat diet and took fish oil supplements had lower levels of pro-inflammatory substances in their blood and a lower cell cycle progression score— a measure used to predict cancer recurrence— than men who ate a typical Western diet, researchers found.
Tiny amounts of a specific type of lipid in the small intestine may play a greater role than previously thought in contributing to clogged arteries. Researchers were able to reduce the negative effects of these lipids in mice by feeding them a genetically engineered tomato, designed to mimic HDL ("good") cholesterol.
More than 90 tons of ready-to-eat salads and sandwiches by a California catering company are being recalled after 26 people in three states were sickened by a bacterial strain of E. coli linked to its products.
The U.S. Food and Drug Administration (FDA) announced its preliminary determination that partially hydrogenated oils (PHOs), the primary dietary source of artificial trans fat in processed foods, are not “generally recognized as safe” for use in food.
Onions now come in a tearless version that scientists are now reporting could pack extra health benefits like their close relative, garlic, which is renowned for protecting against heart disease.
Blueberries are called a “superfood” for their high polyphenol content, but when baked or cooked, levels of some of these substances rise while others fall, which could alter their “super” health benefits.
Coffee consumption reduces risk of hepatocellular carcinoma (HCC), the most common type of liver cancer, by about 40 percent, according to new research.
Human breast milk is sold for babies on several online sites for a few dollars an ounce, but a new study says buyer beware: Testing showed it can contain potentially dangerous bacteria including salmonella.
Spraying a plant hormone on broccoli— already one of the planet’s most nutritious foods— boosts its cancer-fighting potential, and researchers say they have new insights on how that works.
Researchers have found "America’s favorite cookie,” the Oreo, is just as addictive as cocaine– at least for lab rats. And just like most humans, rats go for the middle first.
The World Food Prize Foundation is confronting both opposition to genetically modified crops and the divisive issue of global warming as it gathers this week. The Foundation is awarding this year's prize to three biotechnology pioneers, infuriating environmental groups and others opposed to large-scale farming.
New research explains how a synthetic gene module controlled by the happiness hormone dopamine produces an agent that lowers blood pressure, opening up new avenues for therapies.
Scientists have discovered key details of a brain-to-body signaling circuit that, when activated by combined signals from the neurotransmitters serotonin and adrenaline, enables roundworms to lose weight independently of food intake.
New research has revealed a set of cells in the fruit fly brain that respond specifically to food odors. The degree to which these neurons respond when the fly is presented different food odors can predict how much the flies will like a given odor.
Sixty years ago scientists could electrically stimulate a region of a mouse’s brain causing the mouse to eat, whether hungry or not. Now, researchers have pinpointed the precise cellular connections responsible for triggering that behavior.
Contrary to earlier studies, new research suggests that omega-3 fatty acids may not benefit thinking skills. Omega-3s are found in fatty fish such as salmon and in nuts. The study involved 2,157 women age 65 to 80 who were given annual tests of thinking and memory skills for an average of six years and were also tested for the amount of omega-3s in their blood.
Here’s some news worth spreading: Girls who eat more peanut butter could improve their breast health later in life. Research shows that girls ages 9 to 15 who regularly ate peanut butter or nuts were 39 percent less likely to develop benign breast disease by age 30.
Carbonation, an essential component of popular soft drinks, alters the brain’s perception of sweetness and makes it difficult for the brain to determine the difference between sugar and artificial sweeteners, according to new research. The study also identifies that there is a downside to this effect.
In an analysis of 446 compounds for their the ability to boost the innate immune system in humans, researchers discovered just two that stood out from the crowd– the resveratrol found in red grapes and a compound called pterostilbene from blueberries.
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.
