发帖数: 1283 | 1 I have been wondering why the natural selection has allow gene that is prone
to Acne to survive. This recent article might give a good understanding. I
did increase my omega 3 intake recently and did notice an improvement. This
is to say that I notice much less breakout and less inflammation. However,
cleaning is still essential to get the oil remove from my skin. I hope this
will be of help to those who have been fighting chronicle acne problem.
The historical ratio of omega-6 to omega-3
Throughout 4-5 million years of hominid evolution, diets were abundant in
seafood and other sources of omega-3 long chain fatty acids (EPA & DHA), but
relatively low in omega-6 seed oils.
Anthropological research suggests that our hunter-gatherer ancestors
consumed omega-6 and omega-3 fats in a ratio of roughly 1:1. It also
indicates that both ancient and modern hunter-gatherers were free of the
modern inflammatory diseases, like heart disease, cancer, and diabetes, that
are the primary causes of death and morbidity today.
At the onset of the industrial revolution (about 140 years ago), there was a
marked shift in the ratio of n-6 to n-3 fatty acids in the diet.
Consumption of n-6 fats increased at the expense of n-3 fats. This change
was due to both the advent of the modern vegetable oil industry and the
increased use of cereal grains as feed for domestic livestock (which in turn
altered the fatty acid profile of meat that humans consumed).
Become a Fan of Omega-3 Fatty Acids
Omega-3s have been shown to control the production of leukotriene B4, a
molecule that can increase sebum and cause inflammatory acne.
Omega-3s can be found in supplements or in foods like walnuts, avocados,
flaxseed oil, and salmon. |
