The researchers say their findings call into question current guidelines that focus mainly on saturated versus unsaturated fat amounts, as opposed to concentrating on the food sources of the types of fatty acid. The study was part-funded by the British Heart Foundation, whose associate medical director, Prof. Jeremy Pearson, says:.
Lead author Dr. Rajiv Chowdhury of the University of Cambridge, who describes the findings as "interesting," says they could open new lines of enquiry that carefully question our current dietary guidelines, and adds:. In , more than 17 million people died from a cardiovascular cause globally.
With so many affected by this illness, it is critical to have appropriate prevention guidelines which are informed by the best available scientific evidence. To arrive at their conclusions, Dr. Chowdhury and his colleagues pooled and re-analyzed data from 72 separate studies that included over , participants in 18 different countries. The studies had assessed total saturated fatty acid in two ways: one as a component in participants' diet, and the other way was by measuring levels in the bloodstream.
The results of the pooled analysis showed that whether measured in the bloodstream or as a component of diet, total saturated fatty acid was not linked to coronary disease risk. The analysis also found no significant link between heart risk and intake of total monounsaturated fatty acids, long-chain omega-3 and omega-6 polyunsaturated fatty acids. However, when they looked in more detail at bloodstream levels of individual subtypes of polyunsaturated fatty acids, such as long-chain omega-3 and omega-6 fatty acids, the researchers found they linked to heart risk differently.
For example, they found some evidence that bloodstream levels of eicosapentaenoic and docosahexaenoic acids two main types of long-chain omega-3 polyunsaturated fatty acids , and arachidonic acid an omega-6 fatty acid are each linked to lower heart risk. They also looked in detail at saturated fatty acids.
Here, they found some weak links between bloodstream levels of palmitic and stearic acids predominantly found in palm oil and animal fats, respectively and heart disease, but blood levels of the dairy fat margaric acid appeared to significantly reduce heart risk. Lastly, when they looked at results of trials testing the effects of adding omega-3 and omega-6 supplements to diets, they found no benefit in terms of reducing risk of coronary disease.
Pearson says large-scale clinical studies are now needed before drawing firm conclusions on this new evidence. In the meantime he advises:. Medical News Today recently published an article on adopting a healthy lifestyle to reduce heart risk. The article explains the difference between heart risk factors that cannot be changed like genes, and those that can, and cites smoking, obesity , diet and exercise as the main modifiable ones.

Example: When you grow crystals from an aqueous water solution, you dissolve as much solute into the water as you can, to the point where no more will dissolve. This produces a saturated solution. Although not a technical chemistry definition, saturated may mean thoroughly soaked with as much water or other solvent as possible.
Example: If a protocol asks you to completely saturate a filter paper with solution, this means to thoroughly wet it. If an atmosphere is at its highest humidity level for a given temperature, it is saturated with water vapor.
