Written by | published on

Vitamin A is not exactly known for being an anti-diabetes vitamin. If anything people will associate it with skin health... and SuppVersity Readers probably with anti-cellulite treatments | learn more In the previous installments of this series I have addressed many of the "usual suspects" everyone associates with non-carbohydrate dependent improvements in blood glucose management. In today's installment of this series I will now take a look at an important vitamin of which only few would expect that it is in any way involved in glucose management: Vitamin A - real, pre-formed retinoic acid, not beta-carotene. In view of the misleading news about the "involvement" of retinol binding proteins in the etiology of the diabesity epidemic and the bullocks about the negative effects of vitamin A on vitamin D, the vast majority of health junkies all over the web will probably associate high vitamin A intakes with insulin resistance, not -sensitivity. You can l...

Vitamin A Educates T-Cells, Joins Forces With Vitamin D Against Liver Cancer. Milk Better Than Sugary Electrolyte Solutions for Rehydration? Helicobactor Pylori: Probiotics from Breast Milk & Feces Better Than Amoxicillin!

Lactobacilli are hip, vitamin A is not - at the SuppVersity you still get news on both 1kg! That's the amount of weight you could probably lose if you rid yourself of all the microbes in your gut - from the weight of the bacteria alone, of course. Whether this would be a good idea or not, is however very questionable. On the one hand, we do have the still not fully understood studies on obesity-resistant germ free mice and an accumulating amount of evidence that having the "wrong" bacteria in the gut is at least associated with an increased obesity risk (Blaut. 2012). On the other hand, however, we are seeing new studies on the various benefits of having the "right" gut microbiome being published on an almost daily basis. So what? Before we take a closer look at a definite benefit of having the "right" gut bacteria, though, let's start out with another likewise gut-related news item on the role of retinoic acid in T-cell education. In a way i...

Circadian Rhythmicity: Retinol (Vitamin A) & Caffeine and Their Effects on the Central & Peripheral Clocks of the Body

Image 1: Is it a bad idea to "wake yourself up" with a pot of coffee in the morning, I mean from a circadian rhythm perspective? In the last installment of this series we have been dealing with breakfast. Now, if you are following the mainstream advice neither of the two subjects of this installment should actually be a staple of it. Vitamin A, in its active form, retinol, is "bad and dangerous" and only present in such "evil cholesterol laden foods" such as eggs. And since coffee will sure give you a heart attack, you better stick to your calcium fortified orange juice , a minimal amount of white water , ah.. I mean low fat "milk" (learn more about the difference between white water and milk in " Mutant Milk!? New Research Fuels the Flames on Hushed Up Concerns About Ill Health Effects of Homogenized Milk ") and - of course - " healthy cereals ". And while you will hardly be able to argue that skipping a breakfast like t...

Put the "A" to the "D": Very High Dietary Vitamin A (Retinol, not Beta Carotene!) Content Ameliorates Visceral Adiposity and Improves Insulin Sensitivity in Obesity Prone Rats

Written by | published on

What's the first letter in the alphabet? "D"? Well if you look at current research on vitamins, you would think so. Vitamin D is everywhere, vitamin A - if anything - its toxic antagonist. You, as a faithful student of the SuppVersity know better anyway: balance is where the magic lies; and thus you probably won't be surprised that not vitamin D, but vitamin A supplementation improves insulin sensitivity and ameliorates weight gain in a group of obesity prone rats on their favorite fattening stock-diet ( Jeyakumar. 2011 ). Image 1: Molecular structure of all-trans retinol In the Journal of Diabetes, Obesity and Metabolism , Jeyakumar et al. published the results of an early 3-months intervention with a vitamin A-enriched diet (129mg vitamin A/kg diet) on visceral obesity and insulin sensitivity in 50days old obesity prone (WNIN/ob strain) rats: Compared to stock diet-fed obese rats, vitamin A-enriched diet ...
