The body has a remarkable ability to retain sodium. It seems like the natural order to things is to excrete absolutely minimal amounts of sodium/other minerals in urine and sweat. Ingesting salt simply upregulates the kidney's disposal of salt (and probably potassium, if you supplement that in great amounts.) This switch can take some time (IME, weeks +,) so when one suddenly switches to raw meat + fat from SAD you'll experience bouts of low blood sodium.
Maybe, but I've been eating a RPD diet for more than just weeks and Dr. Wortman reports that his patients' experiences have not matched that claim, and other folks here and at other forums have reported benefits from adding some potassium chloride or sodium chloride back into their low-salt, meat-heavy diets. I doubt it would work for everyone, but it seems worth trying for me. Interestingly, a chiropractor did find my urinary salt levels to be low and he had recommended increasing my salt intake, but he seemed like a quack and I didn't consider that it might really be useful to do so until recently, thanks to what I've learned here and at another forum.
"grass-fed" is not a standard of quality. See the widely varying colors of suet and butter. Deeper yellow-orange fat clearly has greater fat-soluble nutrients. Vitamin K2, probably more A, D, and E too.
Yellowness is also not a guarantee of quality, unfortunately. This suggestion of deep yellow color indicating 100% grassfed and high quality keeps coming up but it doesn't match what I've found at my local market, nor what I was told by the folks at the Hardwick Beef 100% grassfed farm, nor what Van and Delfuego were told by John Wood of the US Wellness 100% grassfed farm. There are two brands of 100% grassfed fats and fat-containing meats at my local market as well as a brand that sells pastured venison, bison and elk meats and all of them have fats much lighter in color than the very-yellow fat from an organic farm that is not 100% grassfed. The organic suet is very yellow but it is not 100% grassfed and other than the yellow color it has the same appearance and awful taste and texture of supermarket suet and is the WORST tasting, looking, and feeling brand sold at the market--not the best. So I don't think the color of fat is a good indicator of whether or not it is 100% grassfed or high quality. It's quite clear that grain-finished cattle can produce very yellow fat, and pretty crappy yellow fat at that.
There are multiple factors that determine how yellow beef fat will be. Van pointed out that Jersey cows and older females produce more yellow fat.
Slankers'grassfed tallow is off-white and the light yellow is only easily seen when the tallow is melted (

Van,
Thank you for bringing this up . . . Interesting read. I have very little spare time in my life and would have never known this was going on.
Our tallow has looked the same from day one. Our omega 3 ratios have been stellar every time they were tested at the ISU meat science lab. No starch is included in the diet from start to finish.
Note PDF attached with a the tallow demonstrating a better ratio of omega 6:3 than two lamb cuts tested in June. Lamb will usually be hard to beat. 1.65:1 is pretty good compared to grain fed at 20:1.
The only things that make any sense are as follows on my best guess:
• Jim Gerrish, PhD grazing guru, who worked for Univ. of Missouri for 20 plus years indicated the trick was to get cattle to gain in excess of 1.5 lbs. a day on quality forage and management to reduce the yellow fat. If done properly you will not see the yellow fat.
• Wheat pasture is famous for yellow fat and a lot of winter wheat pasture can be found in southern Oklahoma and North Texas.
• We only harvest animals under 30 months of age. If cows were in the mix, then one would expect to see some yellow fat.
• The last explanation might be rendering technique involving temperature and how much material is separated off after melting.
In closing, we simply render the suet into tallow/lard like our ancestors did 150 years ago. We add nothing to the product to enhance color, flavor etc. It has always been pearly white in color.
Thank you for bringing this up and feel free to post the pdf.

www.uswellnessmeats.comHere's what John Wood wrote to Delfuego of ZIOH about this same issue: "Our marketing director looked up your blog and spotted a member who took us to task on the white tallow color last fall. I refuse to engage in blog arguments as there are no winners. plus I barely have time to live the way it is.
At the time, I did speak to a colleague that teaches meats at the Univ. of Missouri (Carol Lorenzon PhD) to help answer how you can produce yellow tallow. Number 1, you have animals between the ages of 3 and 6 that have stored up carotenes. The bovine has no surplus until after they hit ~ 30 months. As [they] roll past 6 years, and several gestations, cows will lose carotenes the rest of their lives as they age. Number 2, you have churn the tallow to add air which will make it light and fluffy and make it look like butter. As a kid, we were forced to churn butter with a hand churn. The more you churned it the brighter the yellow color. We do not kill cows and never will. This is a favorite trick in the grass-fed industry and technically still probably in bounds but we have never harvested a cow or bull. Only yearling cattle between 16 and 26 months of age on average. Time depends on genetics and grass growing conditions."
I believe he's wrong about fat having to be churned to be highly yellow, since the brightly yellow grain-finished fat that's sold in my market is clearly not churned. It still has its original shape. The rest of his comments appear to match what I've seen reported from several sources, including Hardwich Beef when I wrote them about this, if my memory serves me correctly.
Lex also attributed whitish fat from 100% grassfed animals to the animals being young (
http://www.rawpaleoforum.com/general-discussion/all-suet-is-white/msg9345/#msg9345). The tallow from 100% grassfed Burgundy pasture beef is also off-white (
http://www.rawpaleoforum.com/general-discussion/all-suet-is-white/msg10990/#msg10990) rather than yellow, as is the excellent quality 100% grassfed suet I get from Hardwick Beef.
John Wood was rather distressed that people were making claims about whitish color indicating that his tallow and suet are not 100% grassfed, so if anyone still doubts that whitish tallow and suet can be 100% grassfed, he probably would appreciate it if you ask him about it instead of posting such claims on the Internet--especially not accusations about "lieing farmers."
Zinc is needed for HCL production.
Thanks for sharing that. I have a history of zinc deficiency and I'm still slightly deficient despite eating tons of raw, 100% grassfed, wild and pastured red meats of many varieties, so that could also be a factor for me.
A lack of HCL causes a lack of zinc absorption, but so does a lack of K2. K2 apparently is needed for mineral absorption.
Interesting, I've experienced an improvement in dental health since I started taking a softgel form of K2, despite the fact that I had been eating raw organs, eggs, suet, marrow, duck legs and other food sources of K2. It seems that some people, like me, have sufficiently damaged intestines and deficiencies from the SAD that we need (temporarily, I hope) more than what raw food alone can provide.
HCL is obviously tremendously important for protein and mineral digestion and absorption; I propose that the lack of HCL production is due to poor mineral absorption from a lack of fat-soluble vitamins. Eating excessive amounts of protein may further disrupt things by requiring far greater HCL and fat soluble vitamins; here we see how excess protein is damaging without sufficient accompanying NUTRITIOUS fat. Supplementing with HCL thus proves to be a temporary bandage, while the real issue will never be resolved without adequate fat soluble vits.
Yes, I think you're onto something here, and this could explain why some people, like me, don't benefit from HCL and why some who benefit from HCL find that the benefit dissappears once they stop taking it--even after lengthy periods of taking it. Presumably the underlying intestinal damage has not fully healed and the malabsorption that results creates nutrient deficiencies that HCL supplements alone, and even with healthy diets, may not be sufficient to resolve in a reasonable amount of time.
