While the recommendation to remove fat was medical advice from your diet for years standard, shows a new review of published studies, that change the types of fats you eat will bring better results.
The study by researchers at the medical school, Norwich in the UK almost 48 studies on saw half a century, and the health benefits of low-fat diet, in which saturated fats have been replaced with carbohydrates, compared to the health benefits of what researchers amended where call fatty diets, saturated fats with unsaturated fatty acids, fish and vegetable oils are replaced.
"There are the total amount of fat we eat, if we replace saturated fats with starchy foods to reduce no clear health benefits," said study author Lee Hooper, senior lecturer in research synthesis and nutrition in Norwich, in a podcast will accompany the study release. "Change the fat in our diet by replacing some of which can the animal or saturated fats with vegetable oils and unsaturated spreads, but the risk of heart and vascular diseases."
The researchers found that all the studies were taken, who reduced and changes that her fat consumption had a 14 percent reduction in strokes and heart attacks. But when she saw the figures further, they found that the effects of all seemed to replace saturated fats with unsaturated. Just reduced fat intake, have a major impact not by substituting fats carbohydrates.
The analysis has been this month in the Cochrane Collaboration published a magazine, in which the results of previous studies together are doctors and type in clinical practice health care professionals.
In the year 2001 Hooper group a similar analysis of 27 studies completed and came to the conclusion that total dietary fat should be reduced, and some saturated fatty acids in the diet with unsaturated fats should be replaced remaining.
Conclusions set to increasingly the new study the saturated fats with unsaturated, while pointing out that it is not clear, what certain unsaturated fatty acids would be best to replace. The researchers also said that it is unclear whether certain unsaturated fatty acids to add would be beneficial for the risk reduction heart.
In explaining the better edited fatty diets, said Hooper "this could be due to a low-fat diet is more difficult to manage and be less effective", but this could be shown not the data.
She also said that the advantages for women have been proven not as strong as they were for men.
The data "suggest that we would benefit all, part of saturated fats with other fats... for at least two years to replace, but not by moving to a lower low-fat diet", said Hooper. "The difficulty is that the data for women is unclear." It stated that it had no studies reported in more than two years, the results of heart disease for women as for men.
Some studies have left questions about the nature of the link between heart disease and saturated fat consumption. The connection was usually made because saturated fatty acids at higher levels of LDL ("bad") cholesterol, is linked, which is in turn linked to heart disease.
But studies have failed to show a specific, direct connection. After such a study last year in the American Journal of clinical nutrition, researchers published with the children's Hospital Oakland Research Institute wrote that while removing saturated fat from the diet a winning strategy in the fight against heart disease had not been, "substitution have been shown by multiple polyunsaturated dietary fat for saturated fat, lower risk of [cardiovascular disease] has."
