New Insights Into the Difference Between Whey, Casein, Cod & Wheat Proteins: Increased Dopamine, Decreased Gastric Emptying, Unknown Hydroxy-Fatty Acids & More

Written by | published on

This is not your average protein shoot-out - the amount of leucine and the mTOR and protein synthetic response were not even measured. It's actually rare to read the phrease "in contrast to previous studies" in a study about whey protein. There have been dozens,... ah, what do I see, hundreds of studies that have investigated almost all aspects of the biochemical, digestive, and health properties of whey proteins and still, there it is: The sentence-starter "in contrast to previous studies" in a paper that's about to be published in one of the upcoming issues of the Journal of Proteome Research . The proteome, by the way, is the entire set of proteins expressed by a genome, cell, tissue or organism at a certain time and a study that compares the acute differential effects between whey isolate, cod and gluten (=wheat) protein on postprandial amino acid, and lipid levels, as well as other metabolites is not what I would be looking for in this journal. ...

Underestimated Vitamin D Sources: Especially Eggs, But Also Chicken, Pork, Fish & Dairy Contain an Overlooked, Physiologically Relevant Amount of Ready-Made 25OHD

Written by | published on

What do you need for a high 25OHD picnic at the beach? Eggs! Regular SuppVersity readers know: The slowly abating vitamin D hype is driving me up the walls. Whenever you search a database for recent articles with the word "vitamin" in it, you are flooded with papers on vitamin D - many of them simplistic adulations without any new data or information. Others are totally irrelevant experiments on cell lines or non-significant epidemiological analyses, where no one can tell you whether the low vitamin D levels are mechanistically or corollarily involved in whatever the scientists are trying to tell you vitamin D was beneficial for. Among all this mess, you can still find a handful of interesting papers. You just have to look close enough to spot gems such as a review by Ovesen, Brot, and Jakobsen (2013). Are Eggs the Best Dietary Vitamin D Source We Have? "Eggs? The best vitamin D source?" I don't have the hubris to say that eggs are the absolute #1, ...

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

Written by | published on

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...

Making the Right Fish Choices: Fatty Acid Contents of 33 Different Fish Species. Plus: What Are the Implications?

Written by | published on

Pollachius virens (Photo: Tino Strauss) is king, when it comes to the n:3/n:6 ratio, but with <1% of fat you will still be hard pressed to get tons of omega-3s from eating pollock... but is more really better, let alone necessary? I have already broached the issue of the differences in the fatty acid composition of fish - even those of the same species - in past articles such as the one(s) on fish as a potential source of mercury in your diet ( read more ). When I saw the recent paper by Claudia Strobel, Gerhard Jahreis and Katrin Kuhnt in Lipids in Health and Disease , I thought that it was about time to supply you with some real data on the actual n:3/n:6 ratio of different fish and its implications for the purported health benefits and anti-obesity effects of regular fish intake. Is there a "super fish" or is it as so often a matter of "mixing and matching" to achieve the right balance? Fish? Of course, I have fish & chips or fish sticks every other...

Fishing for Muscle: Cod Protein Promotes Muscle Repair After Injury More than Casein or Peanut Protein

Written by | published on
Image
Image 1: There are obviously more nutritionally valuable parts to cod than just its liver. On Wednesday, you have learned that diet-deoptimization with rice instead of casein protein is a possible way to gain less weight. Today, we are going to tackle what appears to be a way more promising alternative to the dairy-based top-dogs among the protein supplements: Cod protein! Within the health and fitness community, the cold(er) water fish is hitherto, above all, known for its vitamin-laden liver and the oil humans have been producing from it and consuming for centuries, now. That the arginine-, glycine- and taurine-rich protein of its tasty white flesh could soon replace - or at least complement - dairy proteins (casein, whey) as the physical culturists' go-to protein for muscle building and regeneration will yet probably be news to most of you, right? COD - Canned or dried? Probably doesn't matter as long as you eat it. In a recently published paper on yet another rod...
