,3lnbtana (iazettc HEALTH / SCIENCE Friday, September 19, 2003 - Page 9 Better late than never Even midlife diet change can increase longevity, study suggests By PAUL RECER AP Science Writer ; WASHINGTON — It has long been known that laboratory animals live longer on a low-calorie ttiet. Now a study suggests that even if sensible eating is delayed until middle age, health can be improved and life extended. • A study on diet and life in the journal Science dealt only with laboratory fruit flies, but researchers said some of the same effects may apply to mammals, perhaps even humans. In the study, British researchers compared the effects of different calorie-restricted diets on the mortality of fruit flies. They found that fruit flies on restricted diets lived about 90 days, twice as long as those fed on a normal diet. But the scientists also found that when heavily fed fruit flies were switched at middle age — day 14 to 22 — to leaner diets, then the animals converted from the shorter life pattern of the overfed to the longer-lived pattern of flies that had been on a restricted diet all their lives. The carry-home message from the study, said Linda Partridge of University College London is that it is never too late to improve health by switching to sensible eating habits. "If this works in humans, then it means that from the time a person starts on a restricted diet, they'll be like individuals of the same age who were always on that diet," she said. "Their prospects of survival are the same." Partridge said that although the life-extending effects of short rations have never been proven in humans, it has been shown in monkeys, mice, rats and fruit flies that diet restrictions will lead to longer lives. "There is no reason to suppose it wouldn't apply equally to humans," she said. "There are diet restriction studies now under way with monkeys and all the indications appear the same (as with mice, rats and fruit flies)." James R. Carey, a University of California, Davis, researcher who studies the biology of aging, said the Partridge study is "important to the field," but does not provide final answers about the true effects of restricted diets. He said that fruit flies and other animals on restricted diets tend to stop reproducing. In mammals, for instance, the females stop ovulating and, hence, cannot reproduce. As a result, Carey said, animals on restricted diets may live longer simply because they are not expending energy and stress in the rigors of reproduction. He said studies still need to specifically isolate and prove that it is the lean diet alone that leads to longer life, and not related factors.

CARUSO Associated Press Writer PHILADELPHIA — A trust responsible for distributing a multibillion-dollar legal settlement to people who took a potentially harmful diet drug sued a Missouri cardiologist Thursday, claiming she diagnosed thousands of people as being ill without properly evaluating their health. The suit, filed by the AHP Set- tlementTrust, accuses Dr. Linda J. Grouse of turning her Kansas City, Mo.-area practice into an "assembly line." The suit said Grouse improperly certified people who had taken the drugs Pondimin and Redux as suffering from valvular heart disease. In many cases, the suit claims, Grouse took only a few minutes to evaluate echocardiograms and rarely met patients in person, reviewed their medical records or took a medical history. It said that for 11 months of work, Grouse was paid $3.2 million by law firms representing people who hoped to win a share of the $3.75 billion settlement paid by American Home Products, the company now known as Wyeth that made the medications used in the fen- phen diet drug cocktail. During that time, the trust claims, Grouse signed 2,500 certificates, dubbed "green forms," designating that a person could participate in the settlement. "Dr. Grouse signed these green forms either knowing that many of her representations were false or knowing that she was acting with reckless disregard as to the truth of (lie representations," the suit said. Grouse, who is a fellow of the American College of Cardiology and die American Heart Association, did not immediately respond to phone messages left at her office Thursday. Previously, her attorneys have defended her methods and blamed the accusations on a battle between lawyers, trust administrators and Wyeth over the settlement fund's dispersal. The suit follows a ruling by a federal judge last November that medical claims made by uninjured people were threatening to undermine the 1999 settlement.

Xk'cc*. «X; \k*|)llC\YS By PAUL RECER AP Science Writer WASHINGTON — Researchers working in the Amazon River basin have discovered clusters of settlements linked by wide roads and surrounded by agricultural developments. The researchers, including some descendants of'pre-Co- lumbia tribes that lived along the Amazon, have unearthed evidence of densely settled, well-organized communities with roads, moats and bridges in the Upper Xingu part of the vast tropical region. The findings show the Amazon was not, as was once thought, all an untouched wilderness before Columbus came to the Americas. Michael J. Heckenberger, first author of the study appearing this week in the journal Science, said that the ancestors of the • Kuikuro people in the Amazon • basin had a "complex and sophisticated" civilization with a population of many thousands during the period before 1492. "These people were not the small mobile bands or simple dispersed populations" that some earlier studies had suggested, he said. Instead, the people demonstrated, sophisticated levels of engineering, planning, cooperation and architecture in carving out of the tropical rain forest a system of interconnected vil- lages and towns making up a widespread culture based on farming. Heckenberger said the society that lived in the Amazon before Columbus were overlooked by experts because they did not build the massive cities and pyramids and other structures common to the Mayans, Aztecs and other pre-Columbian societies in South America. Instead, they built towns, villages and smaller hamlets all laced together by precisely designed roads, some more than 50 yards across, that went in straight lines from one point to another. "They were not organized in cities," Heckenberger said. "There was a different pattern of small settlements, but they were all tightly integrated." He said the population in one, village and town complex was 2,500 to 5,000 people, but mat could be just one of many complexes in the Amazon region. "All the roads were positioned according to the same angles and they formed a grid throughout the region," he said. Only a smali part of these roads has been uncovered and it is uncertain how far the roads extend, but the area studied by his group is a grid 15 miles by 15 miles, he . said.
