What’s health?

first_imgBy Faith PeppersUniversity of GeorgiaAs obesity closes in on tobacco as the No. 1 preventable cause of death in the United States, federal nutrition experts have made some changes to the dietary guidelines on the food pyramid.The food pyramid, introduced 12 years ago, is a guide to help people plan what they eat each day. The guidelines built around it offer expert advice to promote health and reduce the risk of chronic diseases.”These new dietary guidelines represent our best science-based advice to help Americans live healthier and longer lives,” said Tommy Thompson, secretary of the U.S. Department of Health and Human Services, in the release report.”Dietary Guidelines for Americans” is published jointly every five years by HHS and the U.S. Department of Agriculture. Following the guidelines can reduce the risk of major chronic diseases.The 2005 guidelines put stronger emphasis on calorie control and physical activity.”Around 64 percent of adults in this country are overweight or obese,” said Connie Crawley, an extension nutrition expert with the University of Georgia College of Family and Consumer Sciences.”Of that number, 30 percent are obese,” she said. “And the number of severely obese people has increased even faster than those who have become just overweight and or mildly obese.”Between 1988 and 1992, only 56 percent of adults were overweight or obese and only 23 percent were obese, Crawley said. And the percentage of children and teens between 6 and 18 years old who are overweight has doubled in the past 20 years to 15 percent.”Genetics haven’t changed that quickly,” Crawley said. “Our eating and exercise habits have.”Not eating right or getting enough exercise can lead to cardiovascular disease, type 2 diabetes, hypertension, osteoporosis, certain cancers and other diseases.In simple terms, the HHS-USDA report says the biggest reason people gain weight is that they take in more calories than they use up. The key is to find the right balance of healthful foods and physical activity.But that’s not easy. “There’s a lot of research now trying to figure that out,” Crawley said. “Certainly, eating more fruits, vegetables and whole grains, as recommended in the guidelines, looks to be very important.”These foods help you cut fats and add fiber to your diet, she said. And they help you feel full. Natural foods like these may have other ways to help control weight, too.The advertising and grocery-space ratio between these foods and unhealthy products needs to change, Crawley said, “so healthier foods are promoted more and more healthy, tasty foods are available to kids and adults.”The guidelines urge Americans to get moving. For adults, they recommend: 30 minutes of activity (moderate intensity) most days to reduce the risk of chronic disease. 60 minutes (moderate to vigorous) to help manage your weight. 60 to 90 minutes (moderate) to lose weight (if you stay on a proper diet).”Moderate” activities are those like gardening or yard work, vacuuming, washing the car or windows, badminton, cycling moderately fast, walking 3 miles per hour, water aerobics, ballroom dancing, volleyball and swimming moderately fast.”Vigorous” activities include fast dancing, cycling, jogging or swimming; playing racketball, handball or full-court basketball; walking 4 miles per hour; power lifting; and digging.The recommendation for weight loss is up from 30 minutes in previous guidelines. “That 30 minutes may be enough to help cardiovascular risk reduction,” Crawley said. “But true weight control does seem to require more, especially as we get older.”It’s OK to break up that time, Crawley said. “The key is sit less and move more. Standing is better than sitting, and moving is better than standing.”The guidelines stress eating more fruits and vegetables, whole-grain foods and nonfat or low-fat milk or milk products.The complete guidelines are at http://www.health.gov/dietaryguidelines/dga2005/document/.(Faith Peppers is a news editor for the University of Georgia College of Agricultural and Environmental Sciences.)last_img read more

Five things we learned from the Champions League

first_img0Shares0000Lionel Messi cut a forlorn figure as he left the Stadio Olimpico pitch after Roma stunned Barcelona© AFP LLUIS GENEPARIS, France, Apr 11 – Roma pulled off one of the greatest Champions League fightbacks to dump Lionel Messi and Barcelona out at the quarter-final stage, while Mohamed Salah continued his remarkable goalscoring form as Liverpool wrapped up victory over Manchester City.Here are five things we learned from the Champions League quarter-final, second legs on Tuesday: Klopp has the better of GuardiolaLiverpool’s manager Jurgen Klopp (L) and Manchester City’s manager Pep Guardiola look destined to compete for the sport’s biggest prizes for years to comeJurgen Klopp has beaten Pep Guardiola more times than any other manager, with Tuesday’s 2-1 second-leg win taking the tally to seven victories from 13 meetings.Two German Super Cup triumphs with Borussia Dortmund against Guardiola’s Bayern Munich bolster Klopp’s head-to-head record, but three consecutive successes with Liverpool in the last four months show that the German clearly has the better of his counterpart for now.Even Guardiola said himself before the first leg that the way his City side play is perfect for Liverpool, and apart from a stirring first-half effort from City in the return game, the quarter-final proved exactly that.City still vulnerable after half-timeManchester City captain Vincent Kompany is on the verge of winning his third Premier League titleFor all their possession and excellent attacking football, Guardiola’s City continue to find themselves caught out shortly after the interval.Although Liverpool’s three-goal burst last week came in the opening 45 minutes, they hit City with quickfire goals in the 59th and 61st minutes when they inflicted a first Premier League defeat of the season on the English champions-elect in January.Cruising towards a title celebration in front of their home fans in Saturday’s Manchester derby, City collapsed after the break as Paul Pogba’s 53rd and 55th-minute strikes set Manchester United on their way to a famous 3-2 win.That Achilles heel resurfaced on Tuesday, as after a rousing first-half performance gave them hope, Salah’s 39th goal of the season all but ended the tie 11 minutes into the second period.VAR debate will rumble onMohamed Salah celebrates after scoring Liverpool’s equaliser on the night© AFP PAUL ELLISPerhaps the turning point in the tie came shortly before half-time when Leroy Sane had a potentially crucial second Manchester City goal wrongly ruled out for offside.UEFA president Aleksander Ceferin in February said that video technology would not be introduced for European competitions next season, citing “lots of confusion”.But VAR will be used at the World Cup and is already in place in Serie A and the Bundesliga. The referee and his two assistants in the Liverpool half failed to notice that it was visiting midfielder James Milner who played the ball back to Sane, meaning that the German winger’s goal should have stood.Dzeko finds cracks in Barca armourEdin Dzeko’s early goal set Roma up for a memorable comeback against Barcelona© AFP LLUIS GENEAn incredible season had seen Barcelona go 40 matches unbeaten in La Liga and the Champions League, but Roma summoned a fightback that brought back memories of Barca against Paris Saint-Germain last season.Eusebio Di Francesco’s hosts — 4-1 down from the first leg — attacked from the off, with Edin Dzeko the driving force that finally pushed Barca into submission.His away goal had given Roma a glimmer of hope, and his sixth-minute strike kick-started a memorable night. Barcelona struggled under a barrage of crosses and set-pieces, with first-leg own-goal villains Daniele De Rossi and Kostas Manolas completing the job from a penalty and a corner respectively.Runaway league leaders come unstuckBarcelona’s Argentinian forward Lionel Messi looks on during the UEFA Champions League round of sixteen second leg football match between FC Barcelona and Chelsea FC at the Camp Nou stadium in Barcelona on March 14, 2018.Manchester City and Barcelona are all but certain to wrap up comfortable league titles in England and Spain this season, but both were unceremoniously dumped out of Europe.While opponents have failed to hurt either team domestically, they have found life tougher in the Champions League. Four of City’s seven defeats this season have come in the competition, with the two by Liverpool following losses at the hands of Basel and Shakhtar Donetsk, while Barca collapsed in dramatic style at the Stadio Olimpico.Juventus look set to claim the Serie A title, but head to the Bernabeu on Wednesday facing a 3-0 deficit. French champions-elect Paris Saint-Germain were dumped out by Real Madrid in the last 16.Bayern Munich, already crowned Bundesliga champions, will hope to be the exception to the rule against Sevilla, with a 2-1 lead to defend in Bavaria.0Shares0000(Visited 2 times, 1 visits today)last_img read more
