Fish vs. Krill Oil, SFA ↔ PUFA - False Advice, Low-FODMAP Diet for Athletes GI Tracts - Nutrition Research Update 9/17

Written by | published on
Image
In contrast to the often-asked krill vs. fish oil question, the issue of PUFA vs. SFA seems to be resolved. At least if we focus on replacing SFA with N-6-PUFA well-controlled RCTs don't show a benefit. If studies are interesting, but there's not enough to dissect for a full SuppVersity  article, they make it to the short news . Today's installment is a nutrition research update and it deals with (1) the often-asked question whether there's a health- or performance-relevant difference between fish and krill oil , (2) the often-heard advice to replace saturated fats in your diet with omega-6 fats to improve your heart health, an advice of which a new meta-analysis shows quite cleverly that it's an artefact due to the inclusion of insufficiently controlled studies, and (3) using the low-FODMAP diet in athletes to reduce gastrointestinal problems that range from burping to diarrhea.

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...

Saturated Fat Makes You Fat! You Read the Press Release - Here is the Whole Story: A Story of Muffins, SFA, MUFA, PUFA, Body, Liver & Visceral Fat and N6s & Lean Mass

I have to admit: Whether a conclusion as general at this is warranted based on the data from a recent study is questionable. Somehow I knew that people would freak out, about a press release I reposted on the SuppVersity Facebook page earlier today ( read it! ). Next to saying that you can eat fructose and not get obese saying that you can eat PUFAs without getting fat is probably as heretic as saying that saturated fat makes you fat... what? Oh yes! You're right, it can be even worse. I mean, imagine you'd say that unsaturated fatty acids are less obesogenic than saturated fats. Ah, come on! That's so mainstream it must be propaganda from the "pharmaceutical enteprise/ cholesterol lowering drug entreprise" [ sic! ], right? Well, I am just looking at the acknowledgements of the study the press release refers. Let's see: "None of the authors have any conflicts of interest to disclose" and "This study was funded by the Swedish Research C...

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...
