You can test your MTHFR gene either directly  or by plugging your raw data from 23andme, or another provider into evaluation tools such as Genetic Genie . If you have no idea what #MTHFR means, here's the Reader's Digest version: MTHFR is an enzyme that is affected by a mutation in the MTHFR gene. The latter encodes the enzyme methylene-tetrahydrofolate reductase a ka MTHFR effectively unless there's a single-nucleotide polymorphism (SNP) affecting the 677th base pair of the MTHFR gene... not helping? Well, let's just say if you have a certain variation of this gene, you're having a hard time processing B-vitamins; and it's not totally unlikely that you're affected : According to  Marini et al. 2008 , this mutation affects 29% of the global population. Previous studies, however, report much lower estimates for prevalence of the MTHFR 677TT genotype, i.e. 10% worldwide, with values ranging from 4 to 18% in the United States, over 20% in Northern China to ...

Still throwing away the yolks? Bad idea... even your gains would benefit from the very part of the egg where most of the nutritional value is hidden. You will have read it in the Facebook News  already (if you didn't subscribe, yet, I can only recommend you head over to facebook.com/suppversity right away): whole eggs build more muscle than egg whites. If that's true, generations of bodybuilders and fitness enthusiasts have literally  thrown away their gains by separating and trashing the yolks of their beloved (? how one can love egg-whites, only is beyond me, anyway ?) egg- whites . In view of the fact that eggs have always been one of  SuppVersity Readers' Favorites  I thought: why shall I stick to only one egg study? Let's check out what else the egg-o-logy has to offer, these days... Whole eggs are also an excellent source of dietary protein Yolk: Triglyceride & LDL ↓, HDL ↑ Eggs Boost Vit Uptake 3-4-fold Egg-o-logy - All About Eggs Eg...

Foods, not supplements should be your go-to potassium source. You've read about the importance of adequate potassium intakes and the lack of potassium (esp. in relation to sodium, where only 10% of the US adults meet the Na:K ratio the WHO recommends to reduce your overall mortality risk) in our diets at the SuppVersity , before ( read more about potassium deficit s). You've also learned that potassium supplements can be necessary during very low-calorie diets where they prevent the paradoxical induction of insulin resistance ( read more about potassium and insulin resistance ). What you haven't read yet, however, is the number Tang et al. put on the effect of supplemental potassium on vascular function in their recent review and meta-analysis in the  International Journal of Cardiology  (Tang. 2016). Learn more about potassium (K) in previous SuppVersity articles: Potassium vs. Diet-Inducded Insulin Resis. In the Lime Light: The Ill Effects of Low K Intake...

Three whole eggs deliver the most effec-tive "dose" of  egg yolk to improve your blood lipid levels - more specifically: triglycerides ↓ and LDL ↓ but HDL ↑ Because of their cholesterol content, eggs have long been touted as a driver of heart disease. As a SuppVersity  reader, you know that there are multiple reasons  why the notion that the consumption of eggs, or rather egg yolks, would increase your cardiovascular disease risk: (a) there's no mechanistic "if your cholesterol is high, your CVD risk is also high"-link; (b) a causative link between the consumption of dietary cholesterol and serum cholesterol does not exist - at least not in the majority of people; (c) substances in egg yolks, in particular, have been shown to modulate the physical characteristics of your lipoproteins ( learn more ) and will thus lower, not increase your CVD risk. Since you know all that, it may seem less important for you than your doctor and other people who may stil...
