A new research finding presented in the Journal of American Heart Assoication indicates that Omega-6 Fatty Acids contained in Vegetable Oils, Nuts and Seeds are good for heart. The recommended daily dosage varies from 1.2 to 2.2 gms a day. Termed as polyunsaturated fatty acids (PUFA) also, they are found to play a crucial role not only in the normal functioning of the heart but also in the development of brain.
The conclusions were reached through a review of meta-analysis of randomized, controlled trials and over two dozen obesrvational, cohort, case/control and econological reports.
The emerging observations showed that people who took regurly Omega-6 were least prone to heart diseases. Examinations of blood levels of Omega-6 in heart patients viz-a-viz healthy pointed to the fact that the former ones had lower levels of Omega-6 in their blood.
In controlled trials assigned to people on a random basis, it was found the incidence of heart attacks is lower in the number of subjects consuming diets containing higher levels of Omega-6 over the lower level consuming ones.
A meta analysis of numerous trials inidcated when saturized fats are replaced with PUFA the risk of heart diseases came down by 24%.
However, the results are subject to the limitation indicated by William Harris, the lead author of the Advisory. He has stated that the focus has to be on a overall healthy dietary pattern and in this regard a single nutirent alone is not enough and could not produce the cure also.
