low thyroid dumps sodium so people with low thyroid needs higher intake.
funny picture.
but this small amount in milk is apparently enough to lower testosterone and increase estrogen in men/humans.
Exposure to exogenous estrogen through intake of commercial milk produced from pregnant cows - PubMed
I read the paper and there is a lot to unpack with this study. I may sit down later and layout my criticizms and we can decide whether they are valid or relevant. But I will mention that there were no control groups. For the male group the study shows that when you have not eaten, and then you eat, your blood hormones are affected. It would have been nice if they had another group that also consumed some food that wasn't milk to see if their hormones changed as well.
I am reminded of a forum member who was sad that his testosterone blood levels came back low but then he admitted he had been drinking heavily the night before the test. Indeed these things can affect the test, as can eating.
S-testosterone decrease after a mixed meal in healthy men independent of SHBG and gonadotrophin levels - PubMed
"We found no change in S-LH or S-SHBG but a decline of S-T of 30% from 60 to 120 min after food intake compared to samples taken in the fasting state. This decline may give false low S-T values and overestimate the number of men with suspected hypogonadism."
So the estrogen study may just show that eating has an effect on serum hormones, whether it's milk or some other food.
I think the greater question is: what is happening when the blood levels of hormones are changing and what does it mean biologically? Hormones are not doing anything productive in the blood (except being transported), so why does this level matter? Presumably it indicates that a person has high activity of that hormone, or at least that is what we commonly assume, or that large amounts of the hormone are being removed (they are in the blood being transported to the liver to be prepped for removal) So if the level changes quickly, does that mean that the hormone is being removed from the body and deactivated? What if the hormone is being taken up by tissues? These are things to consider. Estrogen might be thought of in a different way in some contexts. Since it is aromatized in tissues, the level of it in the blood can sometimes indicate that certain amounts of it are being removed from tissues. This is meaningful in post-menopausal women who have low levels of blood estrogen but high levels of tissue estrogen.
What does that mean. Cows themselves use salt licks to their hearts content. I only know I feel weird from liquids without enough saltEven the Cow is giving low Sodium beverages, why do we need so much Salt.

Yeah, and Peat even had several complications with his health when he was younger. The fact he corrected his health in his later years is even more impressive, considering for most people its usually all downhill the older you get. I'm not in the slightest convinced by most of the anti-dairy science out here.Critics blame Dr Peat for advocating milk as healthy while pointing out the unhealthy aspects of it, but Dr Peat drinks tons of milk and is doing better than most in his age group.

Phosphorus can also be balanced with magnesium. In fact, more phosphorus increases demand for magnesium in plants. Nitrogen has the same effect. That is, more meat = more magnesium.Yeah, and Peat even had several complications with his health when he was younger.

If you have lactose intolerance or maybe whey/casein intolerence you should probably not drink it, obviously. But that missing calcium needs to be made up for elsewhere in the diet.
I think one of Peat's more genius views is the calcium/phosphate ratio. When people neglect their calcium and eat too much phosphorus, they always age prematurely and get inflammatory conditions.
I think Peat references the Maasai a lot in regards to this. Citing many of them get as much as 5,000mgs of calcium a day, and they live really long lives comparatively speaking to other tribes in the same general region.Phosphorus can also be balanced with magnesium.

Ancestral eating seemed to have the same amount of sodium, magnesium, phosphorus (1.5-2g); 1/3rd-1/2 as much calcium, and 7x as much potassium.
Magnesium also lowers aldosterone, PTH, etc. Magnesium also increases IGF-1. Magnesium also is released to unroll inflammation. Magnesium also opposes oxidative/peroxidative stress. Etc.
I wonder why the shift to calcium, though I do notice high calcium:magnesium in baby food (milk, egg yolks, etc).
I think wild animals have a taste for minerals and have a sensitive meter for consumption, they lick rocks until satisfied. I'm not sure how much it ends up beingHow high is their intake of salt? Is it natural or to make them fatter/waterlogged? Do the Babycows also consuming from it?
I'm saying getting more magnesium than phosphorus is likely as sufficient as getting more calcium.I think Peat references the Maasai a lot in regards to this.

But getting more magnesium will likely increase the retention of calcium as well. Personally I don't really likely resorting to the "what did our ancestors do?" argument, but it is true many of them had decent health (albeit some exceptions, like the Inuit which was riddle with heart disease). Many ancestral communities probably drinked boiled greens, which is also a good source of calcium/magnesium.

What are the reasons for higher calcium? Magnesium addresses PTH, serum pH (with help of higher potassium), IGF-1, aldosterone, thyroid, cortisol, nitrogen, etc. It seems anything else can be addressed by raising serum vitamin D 25(OH)D.I agree, that's makes sense from a biological perspective. Magnesium is able to reduce aldosterone, so the retention of calcium is probably much better.

Why does higher phosphorus (without calcium) cause issues? Is it mainly due to lowering serum pH?
How is it increasing calcium and for what reasons? Are they addressed when it is replaced with magnesium?I think it has something to do with soft tissue calcification. When you get too much phosphorus, it increases the amount of calcium in the blood (which is bad). Essentially we end up getting "enough" calcium regardless. However, if we're not eating it, we will leach it out of our skeletal tissue.
