Cod Liver Oil vs. URTI. 2x Higher Fat Oxidation W/ Optimal Workout Timing, Aggressive Diabesity Control, Seaweed & Breast Cancer and NO Supplements Superior to Sugar

Written by | published on

Self-proclaimed experts will say: "No cod liver! It's poison! It has way too much vitamin A... you better pop a kg of vitamin D pills if you want to do something for your health." Really? How do you explain the results of the Robertson study, then? "Grandma was right" - That's if you will the statement of the week - a statement that is verified by the SuppVersity Figure of the Week which is p = 0.04 and describes the probability that the association between the consumption of cod liver oil and a decreased occurrence of upper respiratory tract infects (URTI) Swedish researchers observed in a cohort of 6350 middle-aged and elderly participants in the Tromsø Study 6 , of which Robertsen et al. had actually expected that it would finally confirm the protective effects of high(er) vitamin D levels / intake against respiratory disease. As it turned out, however, neither vitamin D (25-OHD), nor the intake of fish, n-3 capsules or vitamin and/or mineral suppl...

Science Round-Up Seconds: DHA, Algae Oil, Fish Protein, Insulin Sensitivity, Fat Loss & Muscle Gain. Plus: Night Shifts & BPA = Pro-Carcinogenic From Breast to Prostate

It's somewhat ironic that Nurse's are one of the three high risk groups for breast cancer, because they work night shifts to help others. Who the other two groups are? Female military personnel and flight attendants on international flights. If you did already listen to yesterday's installment of the Science Round-Up , you should actually be able to connect the dots between both, the first and second course of today's installment of the Science Round-Up Seconds , and the studies on the effects of DHA on fatty acid metabolism, as well as the fallacies of insufficient, interrupted, or irregular sleep Carl and I have been addressing, yesterday. If all that does not ring a bell, I suspect you missed the show and have not had a chance to listen to the podcast (as usual the Science Round-Up starts in the 2nd hour of the show), yet. In this unfortunate case, I'd suggest you do at least start downloading the file while you take the first bite of today's two cour...

Want to Boost Hormone Production? POP Crude Cod Liver Oil or Industrial Waste: Persistent Organic Pollutants (POPs) in Crude Cod Liver Oil Modulate Steroidogenesis.

Image 1: If you are concerned about the hormonal side(?)-effects of persistent organic pollutants, better make sure you buy pharma- ceutical grade cod liver oil. I know, what you are thinking now: "Not again, the ProfDrAndro anti-fish oil rant ." Yet, this is neither about your beloved fish oil, nor is it ranting. Its an unfortunate fact that environmental poisons such as persistent organic pollutants (POPs) find their way into the food-chain of fish. The fish your shiny cod liver oil pills are made of are no exception from this rule and if the producers did not take (costly) measures to remove these toxins from the crude cod liver oil, chances are the non-dioxin-like POPs have already begun to accumulate in your adrenal coretex ( Colby. 1994 ; Ribelin. 1984 ). So, even if you are a fish-oil enthusiast, give this blogpost a chance and read on... Still ahead of print is a study by Montano and some European colleagues ( Mont...

Too Much of a Good(?) Thing: When Fish Oil Starts Clogging Your Arteries and Fattening Up Your Liver.

Written by | published on

If you are no regular visitor of the SuppVersity, I guess, you are religiously taking your (high dose?) fish oil , day in day out. So what? It probably l owers your total and low density cholestero l (LDL-C; it may reduce your triglycerides and thus improve your insulin sensitivity . Yet, in doing all those "great" things, the unmetabolized and peroxidized remainder of everyone's favorite wonder-supplement begin to clog your arteries and liver - at least, if you believe in the validity of that kind of rodent studies which suggested the usefulness of fish oil, in the first place. Image 1: Micrograph of non-alcoholic fatty liver disease, caused by the same kind of lipid accumulations Shirazi et al. observed in the rats receiving fish oil treatment (image by Nephron ) Shirazi et al. ( Shirazi. 2011 ) recently published a paper reporting exactly that: "Fish oil increases atherosclerosis and hepatic steatosis, although decreases serum cholesterol in Wistar rat...

Fish Oil Makes You Lean and Healthy

Written by | published on
In a very recent study, which is going to be published in the Journal of the International Society of Sports Nutrition Noreen et.al. investigated the effect of  4g/d of fish oil supplying 1,600mg/d eicosapentaenoic acid (EPA) and 800mg/d docosahexaenoic acid (DHA) over 6 weeks on resting metabolic rate (RMR), body composition and salivary cortisol in 44 healthy men and women (34+13y, mean+SD. The results were quite astonishing: Compared to the safflower oil group (SO), there was a significant increase in fat free mass following treatment with fish oil (FO) (FO= +0.5 +/- 0.5kg, SO= -0.1 +/- 1.2kg, p=0.03), a significant reduction in fat mass (FO= -0.5 +/- 1.3kg, SO= +0.2 +/- 1.2kg, p=0.04). and a tendency for a decrease in body fat percentage (FO= -0.4 +/- 1.3% body fat, SO= +0. 3 +/- 1.5% body fat, p=0.08). No significant differences were observed for body mass (FO= 0.0 +/- 0.9kg, SO= +0.2 +/- 0.8kg), RMR (FO= +17 +/- 260kcal, SO= -62 +/- 184kcal) or respiratory exch...

EPA Reverses Insulin Resistance by Modulation of Adipose Tissue Inflammation

Written by | published on
If you are about my age, your mother probably did not tell you to have your *yummie* cod liver oil , did she? Turns out, that was a bad mistake, especially if - other than my mum - your mother relied heavily on convenient foods and did not have an eye on your consumption of candy and dietary fats. The reason I am coming up with childhood memories is the publication of a study by Kalupahan et al. (Kalupahan. 2010) which confirms the positive effect of eicosapentaenoic acid (EPA) on prevention (P) and reversal (R) of high saturated-fat (HF) diet-induced obesity and glucose-insulin homeostasis.  In contrast [to the mice fed a high fat diet without supplemental EPA], mice fed the HF-EPA-P diet maintained normal glucose tolerance despite weight gain compared with the LF group. Whereas the HF group developed hyperglycemia and hyperinsulinemia, both HF-EPA groups (P and R) exhibited normal glycemia and insulinemia. Further, plasma adiponectin concentration was lower in the HF gr...
