How Essential are Omega-6 Fatty Acids + How Much do We Actually Need? Study Says: Requirements May Have Been Significantly Overestimated Due to Methodological Flaws

Written by | published on

I have to admit: Given the high linoleic (N6) acid content of most of the commonly used plant oils in the Western diet, deficiencies are probably rare occur (if at all) mostly in clinical settings. I am quite sure all of you will have read something about the essential fatty acid requirements of mammals before. Unfortunately, I am also quite sure that you will have found recommendations ranging from the "peatarian" zero (as in "beware of essential fats, the are toxic") to the "Robb Wolff fish oil calculator bullocks" of the early days which recommended copious amounts of omega-3s and allowed for at best zero omega-6s in your diet. One of the reasons that the opinions on human essential fatty acid requirement diverge in the aforementioned ways is that scientific evidence to form an educated unbiased opinion on how much of these precious fats we actually need is scarce. More important than basal fatty acid requirement are the correct frying oils ...

There is More To Glucose Control Than Carbohydrates (2/?): Non-Carbohydrate Nutrients And Their Effects On Blood Glucose Management ➲ SFA, MUFA PUFA, TFA & Co - Fats!

Some say "fat is a mistake" others say "it was our fattest mistake to believe just that" - who is right? Or are things eventually more complicated than that? In the last installment of this series , we've covered the relatively well-known, but rarely well-understood beneficial effects of protein on glucose homeostasis in humans (⤷ go back and read it). This week we will make a fat transition (all puns intended) to the 2nd macronutrient that exerts non-carbohydrate dependent effects on glucose homeostasis: FAT! We have known for decades that the acute glycemic response is affected by the fat content of the diet. As my German "friends", Martina Heer and Sarah Egert, whose recent paper in the scientific journal Diabetes/Metabolism Research and Reviews inspired me to write this article series point out, a recent meta-analysis of the existing literature on low-carbohydrate + high-fat diets suggests that these diets, unlike high-carbohydrate a...

Fish Oil or GLA to Treat Acne Vulgaris? Controlled Human Trial Confirms: 2g EPA + DHA or 400mg GLA do the Trick!

If you want to know how to get of pubertal acne, you got to ask professional pubescents ;-) The study at hand is not only the first experimental verification of the efficacy of omega-3 + gamma linoleic acid supplementation in acne treatment, it's also "paleo approved", because it cites a study by no one else but Loraine Cordaine himself ;-) Don't worry, I am just kiddin' around. In spite of the fact that Cordain's study "Acne vulgaris: a disease of Western civilization" (Cordain. 2002) is in fact the #1 on the reference list, the scientists from the Seoul National University College of Medicine refrain from (paleolithic) dairy bashing in their evaluation of "the clinical efficacy and safety of omega-3 fatty acids and of GLA for the treatment of mild to moderate facial acne." (Jung. 2014) If you google "natural acne treatment" it will usually not take long until you find a reference to fish oil and gamma linoleic acid (a...

Sesame Powered High Omega-6 Diet Boosts Endurance Performance in Rodents - High Omega-3 Diet Sucks: Intra-Muscular Lipid Ratios Determine Exercise Performance

At least in rodents omega-6s appear to make abetter match with exercise than in human beings. I actually referenced this study several times in the past. It came up in a Facebook conversation I had with Roy Nelson who pointed me to a press release telling me that ( I quote ) "Certain Fat Could Help Humans Lose Weight". Interestingly, the "certain fat" in this particular study is (brace yourselves) linolic acid, better known as "omega-6" (obviously a misnomer, since omega-6 is actually referring to a whole class of fatty acids). In view of the fact that the corresponding study in which Rogowski et al. observed a significant correlation between the omega-6 fatty acid content in the muscle and mitochondrial uncoupling and fat oxidation. The problem with the study is however that it was conducted not just with mice, but with genetically modified mice. The results of the said study by Rogoswki, Patin et al. may thus form the basis for further investiga...

Standard American Diet Has 'Optimal' Fatty Acid Ratio to Induce Diabesity. Plus: Study Shows Doubling Saturated Fats Would Yield More Benefits Than Halving Them

Study confirms: The SAD diet yields 'optimal' results (img. forbes.com) Since this post is already lengthy enough, I will spare you how saturated fatty acids have long falsely been accused as the sole driving force of the western obesity epidemic and how the tides appear to be slowly yet steadily appear to be turning, as scientists delve deeper and deeper into the interactions of the total fat content in the diet, its fatty acid composition and the interaction of both with the two other macronutrients and their specific forms and get right to the study at hand. A study that appears in the current issue of the Journal of Lipid Science and deals with the first of the aforementioned interactions. The one that focuses on the total fat content and the individual fatty acid make-up of the diet (Enos. 2012). Fat shoot out: Saturated vs. mono vs. PUFA As Enos et al. point out, the main purpose of their study was to examine the effects of three high fat diets differing only wi...
