Diet for pre-Operative Fitness

Posted by: admin on: May 2, 2012

Pre- operative simple protein free diet could avoid all post-operative surgical complications say Harvard researchers.


Researchers from Harvard School of Public Health found that limiting protein or amino acid intake several days before surgery may reduce the risk of surgical complications.
According to the School of Public Health study, published in Science Translational Medicine, dietary intake of amino acids and protein before surgery might increase chances of health complications such as heart attack or stroke.
Previous studies over the past few decades have suggested that long-term dietary restrictions can extend longevity and slow the aging process. A recent study also demonstrated the benefits of restricting protein with fruit flies.
“What we found was that a brief dietary intervention in a mouse could protect against [surgical complications],” Mitchell said. “We wanted to know what the nutritional and genetic basis of that protection is.”
Researchers analyzed two groups of mice, with one group allowed to eat normally for 6 to 14 days while the other group ate an amino acid or protein-free diet.
When both groups were placed under surgical stress, 40 percent of the mice with a normal diet died. All of the mice with amino acid and protein-free diets survived.
According to Mitchell, he said he plans to further elucidate the nutritional basis and the underlying genetic mechanisms behind the study’s discovered link.
Mitchell said that before this research can be translated to the clinical level, his team of researchers still needs to determine the optimal diet—and how long it should be maintained—for it to be effective.
