For decades, we’ve have been suffering from the false propaganda that low fat and fat-free dairy products, such as the fat found in full cream milk, was supposed to be bad, as saturated fat increases your risk of heart disease and stroke.
A new study in the American Journal of Clinical Nutrition is the latest in an increasingly large body of research that proves that nothing could be further from the truth.
However, they reached their conclusion in a very untraditional way.
Researchers from Tufts University and the University of Texas examined 2,907 American seniors that were aged 65 and upwards.
They measured the levels of fatty acids of three dairy products in their participant’s blood streams in 1992, when the study began, and again six and 13 years later.
During this period, they also monitored who developed cardiovascular diseases and who passed away.
During the 22 years of monitoring the participants, 2,428 people died: 833 died due to heart disease and 1,301 died due to cardiovascular events.
None of the three dairy fatty acids – pentadecanoic, heptadecanoic, or trans-palmitoleic acids – were found to increase the risk of death through cardiovascular events, nor were they found lead to the other deaths.
Those who had a higher amount of heptadecanoic fatty acid in their blood were actually less likely to die of heart disease than their peers.
Furthermore, those who had higher overall dairy fatty acid levels in their blood were 42% less likely to die of stroke when compared with their peers.
This study is scientifically more reliable than most other studies that look at the health of dairy fat, as it did not rely on participant’s recollections of their dietary habits. Rather, it measured the dairy fats in their blood.
Moreover, it included several measurements over time and followed the participants for over 22 years, a long time for a study to continue, and thus increasing its reliability.
