On Monday, researchers at the Harvard School of Public Health released study results showing that red meat consumption was associated with a higher risk of early death. The more red meat -- beef, pork or lamb, for the purposes of the research -- study participants reported they ate, the more likely they were to die during the period of time that data collection took place (more than 20 years). So what is it in red meat that might make it unhealthy?   No one is sure, exactly, but the authors of the Harvard study mention a few possible culprits in their paper in the Archives of Internal Medicine .   First, eating red meat has been linked to the incidence of heart disease.  The saturated fat and cholesterol in beef, pork and lamb are believed to play a role in the risk of coronary heart disease .  The type of iron found in red meat, known as heme iron, has also been linked to heart attacks and fatal heart disease.  Sodium in processed meats may increase blood pressure, which is a risk factor for heart disease. Other chemicals that are used in processed meats may play a role in heart disease as well, by damaging blood vessels.

BEIJING - The sensational Chinese murder investigation in which the wife of an ousted Politburo member stands accused of poisoning a British expatriate may include evidence from blood samples taken from the victim's body before cremation, according to people familiar with the case. Henry C. Lee, a forensic scientist who gained international recognition for his work in the O.J. Simpson murder trial, said that he was asked this year to analyze a blood sample that most probably came from Neil Heywood, the dead Englishman.

The Food and Drug Administration on Thursday cautioned consumers against using quinine for leg cramps, warning that the drug could cause severe side effects, including death. Quinine, sold in this country under the brand name Qualaquin, is approved for treatment of uncomplicated malaria, but has a long history of use as a remedy for leg cramps, especially at night. In many countries, it is sold over the counter. Studies have shown that it can reduce the incidence of cramps by one-third to one-half but that as many as one in every 25 users can suffer serious side effects.

It's called Lot 160, a 5-inch glass tube that's unremarkable in every way - except that it purportedly held blood drawn from President Ronald Reagan as he lay struggling for life after an assassination attempt. The vial, partially coated with a ring of a residue, is being offered for sale by a British online auction house where bids Tuesday reached nearly $15,000. A label and an accompanying document identify it as having contained a blood sample taken from Reagan at George Washington University Hospital on March 30, 1981, the day he was shot outside aWashington, D.C., hotel.

In an age of long commutes, late sports practices, endless workdays and 24/7 television programming, the image of Mom hanging up her dish towel at 7 p.m. and declaring "the kitchen is closed" seems a quaint relic of an earlier era. It also harks back to a thinner America. And that may be no coincidence. A new study, conducted on mice, hints at an unexpected contributor to the nation's epidemic of obesity - and, if later human studies bear it out, a possible way to have our cake and eat it too, with less risk of weight gain and the diseases that come with it. Just eat your cake - or better yet, an apple - earlier.

WASHINGTON - Hall of Fame quarterback Joe Montana said they improved his strength and posture. Celebrity Kim Kardashian boasted they allowed her to ditch her personal trainer. But federal and state officials said the rocker-bottom Shape-ups and other toning shoes made by Skechers USA Inc. don't live up to the hype from the company and its high-profile endorsers. On Wednesday, the Manhattan Beach company agreed to pay $50 million to settle false-advertising allegations by the Federal Trade Commission and the attorneys general of 44 states, including California, as well as the District of Columbia.

Manny Hamelburg, 68, a retired businessman, had fought prostate cancer for years. First, he tried radiation, then a drug with side effects that nearly killed him, and finally Lupron, a drug that blocks production of testosterone, the hormone that can fuel prostate cancer. The cancer disappeared. But life was miserable. Without normal levels of testosterone, Hamelburg says, he had no energy, and "zero libido for seven years. I was like a eunuch. I was chemically castrated. Sex was just hugs."

The PSA test should be abandoned as a prostate cancer screening tool, a government advisory panel has concluded after determining that the side effects from needless biopsies and treatments hurt many more men than are potentially helped by early detection of cancers. At best, one life will be saved for every 1,000 men screened over a 10-year period, according to the U.S. Preventive Services Task Force. But 100 to 120 men will have suspicious results when there is no cancer, triggering biopsies that can carry complications such as pain, fever, bleeding, infection and hospitalization.

"Oh, you mean the guy with the 70-year-old head and the 20-year-old body-builder body? That picture has got to be Photoshopped." Dr. Jeffry Life smiles when I tell him about the general reaction I get about the famous picture of him with his shirt off, the shot that turned a mild-mannered doctor in his mid-60s into a poster boy for super-fit aging and controversial hormone replacement Appearing in medical-clinic ads in airline magazines and...

WASHINGTON - An experimental treatment for multiple sclerosis has caused death, strokes, nerve damage and abdominal bleeding and has no proven benefits for sufferers of the disease, the Food and Drug Administration warned Thursday. Known as liberation therapy, the treatment targets chronic cerebrospinal venous insufficiency - or CCSVI - a narrowing of the veins in the head and neck. It involves inserting balloons or stents into veins to widen them in an attempt to relieve the symptoms of MS. The FDA received reports in 2011 of a patient who died from bleeding in the brain after undergoing the treatment and another who was left permanently paralyzed by a stroke.

Los Angeles County Chief Deputy Dist. Atty. Jackie Lacey gave conflicting testimony under oath during two union grievance hearings, attributing the contradiction to being confused and having problems with her blood sugar level, according to transcripts reviewed by The Times. Lacey, who is running for district attorney and has won major endorsements from newspapers, including The Times, testified under oath in 2009 and 2010 as part of a county employment dispute in which the union representing prosecutors accused the district attorney's office of retaliating against its officers.

Dodgers Manager Don Mattingly said Sunday that the team doctor told him second baseman Mark Ellis was within several hours of possibly having his left leg amputated if Ellis hadn't had emergency surgery. "That was scary," Mattingly said of the injury, which is expected to keep Ellis out of action for six weeks. "I didn't realize how bad that was. " Ellis, 34, suffered the injury Friday when he was upended by the St. Louis Cardinals' Tyler Greene to break up a double play.

The Dodgers won another game, but lost another player. On the same day they defeated the defending World Series champion St. Louis Cardinals, 6-0, second baseman Mark Ellis underwent an emergency leg operation that is expected to sideline him for a minimum of six weeks. Ellis, who was injured when Tyler Greene of the Cardinals slid into him at second base the previous night, had blood and fluids drained from his left leg. He is scheduled to be hospitalized until Tuesday. He became the fourth Dodgers starter on the disabled list.

Those long commutes so typical of Southern California may be doing more than boring you and raising your fatigue level: They also raise your blood pressure and make you fatter, researchers reported Tuesday. For higher blood pressure, the effects kick in at about 10 miles, while for obesity they show up at about 15. Those who traveled the farthest to work every day were also those who were least likely to get adequate exercise. They probably also were more likely to eat fast food and to snack in the car, and were more highly stressed.

A man suspected of killing his girlfriend and their two young sons is in jail while authorities continue searching for the bodies after unsuccessfully combing an Orange County landfill Friday. Shazer Limas, 31, of Orange was booked on suspicion of murder in the deaths of Arlet Hernandez, 31, and their sons — a 2-year-old and a 3-month-old. Limas was arrested late Thursday after a long police chase and standoff that closed Interstate 5 in north San Diego County near the San Onofre nuclear plant, backing up traffic for miles in both directions.

Early in"Snow White and the Huntsman,"several droplets of blood fall to the frozen ground in extreme slow motion, a sample not only of the menace to follow but also of first-time director Rupert Sanders' truly painstaking attention to detail. The shot was the last sequence filmed by the veteran commercial director, and no matter how hard the crew tried, the production's artificial serum never had the proper viscosity or splatter. "It just looked like raspberry jam," Sanders said.

Rats fed fructose-laced drinking water for six weeks performed more slowly in a maze-navigating task, UCLA researchers have found. (Read this L.A. Times opinion article .) They think the effect is due to changes in the way the brain responds to insulin as a result of exposure to fructose. “Our study shows that a high fructose diet harms the brain as well as the body,” study senior author and UCLA professor Fernando Gomez-Pinilla said in a release about the finding, which was published in the Journal of Physiology (postdoc Rahul Agrawal was first author)

Teas from across the globe are becoming more and more popular in the U.S. One relative newcomer, yerba mate, is attracting fans for its allegedly jitter-free caffeine boost and high antioxidant content. Lab research suggests some potential health benefits from drinking yerba mate, but studies of lifelong yerba mate drinkers in the tea's native South America suggest the brew increases the risk of some cancers -- a fact most marketing campaigns omit.

SAN DIEGO — A Marine staff sergeant pleaded not guilty Thursday to a charge of murdering the 22-year-old wife of a fellow Marine as the prosecutor announced that the victim's blood and a possible murder weapon were found in the defendant's car.
