If you ask people to eat less fat to prevent heart disease, it would be a very simplistic look at the whole problem. A broad study which was recently conducted by an international team found that there are scant association with the consumption of saturated fats and cardiovascular diseases. The study indecently goes on to reveal that there is no general effect high levels of the so called healthy polyunsaturated fats like Omega 3 and Omega 6 on the risk of cardiovascular disease.
However specific strains of fats do have an impact on coronary heart disease. 2 varieties of saturated fat which is found in palm oil and animal products were associated with coronary ailments while a kind of dairy fat known as margaric acid is protective. In the same way 2 types of omega-3 fatty acid found in oily fish – EPA and DHA – and the omega-6 fat arachidonic acid were linked to a lower risk of heart disease. The study however reveals that popular omega-3 and omega-6 supplements appeared to have no benefit.
The latest revelation will surely lead to a spurt in new scientific inquiry and also help to reassess the current nutritional guidelines. Cardiovascular diseases are the number cause of mortality and disability around the globe and what we eat have a large impact on the risk of cardiovascular diseases. Therefore best evidence must be used to regularly review the nutritional guidelines.
The results of the study is about to appear in the ‘Annals of Internal Medicine’. The research involved data collected from 72 studies in more than 600000 subjects stretching across 18 countries.
The team, whose results appear in the journal Annals of Internal Medicine, conducted a ‘meta-analysis’ of data from 72 studies involving more than 600,000 participants from 18 countries. The pooling of the data is a very powerful tool which can reveal many hidden trends.
Professor Jeremy Pearson, associate medical director at the British Heart Foundation – which co-funded the study, said: ‘This analysis of existing data suggests there isn’t enough evidence to say that a diet rich in polyunsaturated fats but low in saturated fats reduces the risk of cardiovascular disease. But large scale clinical studies are needed, as these researchers recommend, before making a conclusive judgment.”
