typical

Comparing data from two time periods, 1988-1994 and 1999-2004, the study showed that over-consumption of sugary beverages is widespread, with 84 percent of teens consuming SSBs on a typical day. An adolescent male who consumes the average amount of SSBs per day (356 calories) would need to jog for an hour or walk for more than three hours to burn off these excess calories. The study also showed that the num ber of SSB calories consumed by children ages two to five and six to 11 increased from the previous decade. In particular, the study shows that children ages six to 11 consumed 20 percent more calories from sugar-sweetened beverages in 1999-2004 compared with the 1988 to 1994 period. The study also noted a more rapid increase in SSB calorie consumption among Black and Mexican American youth.

am vazut multe(2006-08-15) -- Climate change is affecting the intensity of Atlantic hurricanes, and hurricane damage will likely continue to increase because of greenhouse warming, according to a new study. "The large increases in powerful hurricanes over the past several decades... certainly suggest cause for concern," the researcher said. "These results have serious implications for life and property...."

children

A recent study published in Pediatrics and led by researchers at Columbia University Mailman School of Public Health found that sugar-sweetened beverages (SSBs) are an increasingly large part of children and teens' diets. Teens who consume SSBs, which include sodas, fruit drinks and punches, and sports drinks, drink an average of 356 calories per day, a significant increase from 10 years earlier. The findings sugges t that reducing empty caloric intake by limiting these drinks may be a key strategy for promoting healthy eating and preventing excess weight gain.

am vazut multe(2006-06-22) -- Global warming accounted for around half of the extra hurricane-fueling warmth in the waters of the tropical North Atlantic in 2005, while natural cycles were only a minor factor, according to a study from the National Center for Atmospheric Research appearing in the June 27 issue of Geophysical Research Letters.

glucose

Sucrose also contains both glucose and fructose, bound together in a 1-to-1 ratio. However, the researchers found that for the sucrose in the beverages tested in this study, the bond between fructose and glucose is broken. Because of this, the authors suggest that the body does not readily discriminate between beverages sweetened with sucrose and those sweetened with HFCS 42 or 55.

am vazut multe(2005-10-14) -- New evidence from climate records of the past provides some of the strongest indications yet of a direct link between tropical warmth and higher greenhouse gas levels, say scientists at the University of California, Santa Barbara. The present steady rise in tropical temperatures due to global warming will have a major impact on global climate and could intensify destructive hurri canes like Katrina and Rita.

types

Much of the evidence that linked corn sweeteners with obesity came from animal-based metabolic studies using pure fructose. This study, on the other hand, used beverages sweetened with two types of high-fructose corn syrup: HFCS 55, which contains about 55 percent fructose and 45 percent glucose; and HFCS 42, which is about 42 percent fructose and 58 percent glucose.
