In my previous post I talked about the importance of fatty acids and how they reduce inflammation and induce expression of PPAR´s. In my clinical practice we never measured fatty acid profiles and ratio´s but this may become routine soon as a higher omega 3 levels have been associated with improved health outcomes.
A recent study in marmots suggests that the fatty acid levels in internal organs are dependant on seasonal variation with high levels of omega 6:3 being observed during the winter months when body temperature is lower. As humans are mammals, it is suggested that these results could be translated from marmots as it has been shown previously that the number of heart attacks increase when the ratio of omega 6:3 is at its peak at the end of winter.
Interesting results, however a bit preliminary and may even through a spanner in the works on exactly how increasing “good fats” work. We also have to remember that increasing dietary omega 6:3 intake is highly dependent on not only seasonal variation but also dietary intake, with Halloween, Thanksgiving and Christmas all happening at the end of the year, it is of no surprise that serum levels of omega 6 may just (coincidentally) be higher at the end of winter.
