Washington: Altering taste buds` sensitivity to fatty food can help shed the flab, say researchers. A team at Deakin University has found that eating a high fat diet can desensitise a person`s ability to taste fat in foods which may lead to overeating of fatty foods andsubsequent weight gain. The study, published in the `International Journal of Obesity and Clinical Nutrition`, builds on the discovery last year of a sixth taste that is responsive to the fat content offoods. "Last year we revealed the results of a study that found fat can be added to the tongues taste repertoire, joining the other known tastes of sweet, salt, sour, bitter and umami (inprotein rich foods). "What we have found now is that the taste buds of overweight and obese people are less sensitive to fat in foods and that this could be a reason for their overconsumption offatty foods," team leader Prof Russell Keast said.For the latest study, participants were placed on a low fat diet for four weeks and a high fat diet for four weeks. Their ability to taste fat pre- and post- diets was tested."We found that placing people on a low fat diet for four weeks significantly increased their ability to identify low concentrations of fat. When the same people were on a high fat diet, the sensitivity to fat did not change in the overweight people, whereas there was a significantly reduced sensitivity for those in the healthy weight range.
