Anemia affects infants' cognition, memory

New research reinforces earlier connections that have been found between iron-deficiency anemia in infants and their neurophysiological development.

Iron-deficiency anemia (IDA) in infancy appears associated with deficits in attention and memory development.

The study findings, reported in the August Pediatrics, reinforce previous research that found lower cognitive test scores among infants with iron deficiency than among those with healthy levels of iron.

Trans fats to be banned to halt rise in obesity

Harmful artificial trans fats are to be banned as figures yesterday revealed that more than half of the population could be obese within 25 years. Researchers claimed that 86 per cent of men were expected to be overweight in 15 years and 70 per cent of women within 20 years.

Comment: Although the ban on trans fat is a good start, there are a lot more causes to obesity. Two among them are MSG and gluten, which most people in the West consume every day.

Is gluten from grains making you sick?

Gluten Intolerance, also known as Celiac Disease, was once thought to be a rare genetic disorder until 2003 when it was discovered that it is, indeed, quite common. Where once gluten intolerance was thought to affect 1 in 4000 people it is now thought to affect 1 in 133 and researchers expect that number to drop even lower. Yet, even with this new discovery many people in America are going undiagnosed.

How does the opioid system control pain, reward and addictive behavior?

The opioid system controls pain, reward and addictive behaviors. Opioids exert their pharmacological actions through three opioid receptors, mu, delta and kappa whose genes have been cloned (Oprm, Oprd1 and Oprk1, respectively). Opioid receptors in the brain are activated by a family of endogenous peptides like enkephalins, dynorphins and endorphin, which are released by neurons. Opioid receptors can also be activated exogenously by alkaloid opiates, the prototype of which is morphine, which remains the most valuable painkiller in contemporary medicine.

By acting at opioid receptors, opiates such as morphine or heroin (a close chemically synthesized derivative) are extremely potent pain-killers, but are also highly addictive drugs.

Expecting an afternoon nap can reduce blood pressure

Where does the benefit lie in an afternoon nap" Is it in the nap itself--or in the anticipation of taking a snooze" Researchers in the United Kingdom have found that the time just before you fall asleep is where beneficial cardiovascular changes take place.

This finding is part of a study entitled Acute Changes in Cardiovascular Function During the Onset Period of Daytime Sleep: Comparison to Lying Awake and Standing, found in the online edition of the Journal of Applied Physiology, published by The American Physiological Society. The study was conducted by Mohammad Zaregarizi, Ben Edwards, Keith George, Yvonne Harrison, Helen Jones and Greg Atkinson, of the Liverpool John Moores University in Liverpool, U.K.

Illinois firm recalls beef patties on E.coli scare

J&B Meats Corp. is recalling 173,554 pounds (78.7 tonnes) of frozen ground beef products sold under "Topps" and "Sam's Choice" labels due to possible E. coli contamination, the U.S. government said this weekend.

The Coal Valley, Illinois-based company produced the patties in June and distributed them to retail stores nationwide, the U.S. Agriculture Department's Food Safety and Inspection Service, or FSIS, said in a statement.

Corporate Agribusiness Is Behind Our Deadly Food Supply - An E. coli outbreak in China could spell disaster in your own dining room

First it was spinach. Now it's green onions at the Taco Bell. What's next? The growing anxiety over our nation's food supply is enough to make you chew your nails -- unless of course they're contaminated with E. coli as well. Is nothing safe?

In the United States today, 80 percent of beef is slaughtered by four companies, 75 percent of pre-cut salad mixes are processed by two companies and 30 percent of milk is processed by just one company. Most of our fresh produce comes from the same region of California where the contaminated spinach and now green onions were grown. During off seasons, up to 70 percent of the produce sold in the United States comes from other countries.
