Effects of elevated calcium on learned helplessness and brain serotonin metabolism in rats. - PubMed - NCBISource?
It matches my experience with regards to mood / depression and I also take carbonate. I would also add that calcium really helps with energy and perhaps this is what makes is an "anti depressant?I also notice calcium helps with with depression. Calcium carbonate is the one I use, I feel it raises dopamine considerably. Unfortunately I always seem to get irritated intestines. I wish there was a way to take calcium carbonate on a regular basis without getting the intestines irritated.
I don't think so. If you search for causes of hyper or hypocalcemia, you'll find everything but the amount of dietary calcium.Is serum calcium level much of an indicator?
The reason I ask is that blood test for me showed - Serum calcium level 2.46 mmol/L [2.2 - 2.6] but I feel my mood improves when I take supplemental calcium carbonate
there is little room in which the PTH-vitamin D endocrine system can operate when calcium intakes are already low. That does not mean that ECF [Ca2+] regulation suffers.
If I'm not wrong, that water content of potatoes is 80%. The reported values in dry weight have to be adjusted for it dividing by 5 (20%). They end up being close to ours.Effect of Soil Characteristics on Potato Tuber Minerals Composition of Selected Kenyan Varieties
This one may be a decent source of references : Phosphorus balance in potato tubers - [PDF Document]
I don't know about the reliability of this quote:
Cooking Methods May Help Dialysis Patients Control Phosphorus
"Frying potatoes in oil lowered phosphorus content by 37%, whereas steaming them reduced phosphorus content by 27%. Roasting frozen hake in oil led to a 49% decrease in phosphorus content. Soaking pork in water and then roasting it in oil led to a nearly 12% decrease in phosphorus content. Eliminating the soaking step eliminated this decrease, the investigators noted.One could use a high calcium water to steam them, but anytime I used the carbonated one for rice I had problems, although that may have had to do with an anti-acid effect (?). I wonder if steaming would allow for the calcium content to increase without any interference with digestion.
Boiling increased the calcium content in all foods because of calcium absorption from the hard water.."
Tyw mentioned that Asians had less of a need for calcium intake, could the lowish phosphorus content of white rice be a reason?

My point was that within the same country some of the variations in the calcium / phosphorus ratio of potatoes are important, I can only imagine what variations there are between different continents, I remember fondly those potatoes from Egypt back in the days of 2016. Fertilisers are worth a thought as well.If I'm not wrong, that water content of potatoes is 80%. The reported values in dry weight have to be adjusted for it dividing by 5 (20%).

As far as I know, it's not necessary to use water that's high in calcium, it can be added later on as an ingredient to the meal and it must work just as well.
How would the calcium migrate from water to the food with steaming? Maybe I misunderstooded what you had in the mind.
Is it possible that carbonation makes it more difficult for the water to enter the rice grains? This should not make a difference for steaming.

- Requirements of calcium: are there ethnic differences?
"Oriental people usually have smaller body frame and skeletal mass than Caucasians (it's just a coincidence), it is logical to consider that less mechanical stress, hence lower bone mass, may be required by Oriental women to support their smaller body weight when compared with Caucasians. In fact, studies have shown that racial difference in bone density disappeared after confounding factors of body weight and height were controlled in comparing ethnic difference in bone density[9,46]."
"[..]high intakes of protein and sodium are proven to induce a higher urinary calcium loss[80,81]. In affluent societies a greater allowance for calcium intakes is recommended because of the high consumption of animal proteid and sodium."

On the other hand, now I'm not sure.
The variation is a good point.My point was that within the same country some of the variations in the calcium / phosphorus ratio of potatoes are important, I can only imagine what variations there are between different continents, I remember fondly those potatoes from Egypt back in the days of 2016. Fertilisers are worth a thought as well.
Ov course steaming vouln't work, and boiling might give similar issues as with the rice: anti digestive juices effects. There wasn't any problem with water infiltrating the rice. I wonder how carbonated drinks and water affect digestion, some people hate carbonated water.
Thanks for the links.
Yes without dark leafy greens it's almost impossible to end up with a nice ratio, so perhaps doing other tubers and rice as starchy foods would be more manageable, the rice doesn't increase the phophorus content as much.The variation is a good point.
Check this out:
Nutrient composition of the potato
Béatrice Mouillé, U. Ruth Charrondière, Barbara Burlingame, NeBambi Lutaladio (..in case it goes the broke. It will.)
I guess what we can conclude from these is that on the best situation you'll still have an undesirable ratio, at least twice as much phosphorus than calcium, but likely much worse given that their sample size for calcium was large and the maximum was considerably lower than the minimum for phosphorus. It's preferable to just suppose that it is always like that and make up for it elsewhere.
I don’t think insects are a good form of calcium
- The effect of dietary calcium and other nutritionally relevant divalent cations on fatty acid-soap formation | Natascha Stroebinger -- @Kartoffel (Endotoxin und Mahlzeitenzusammensetzung)
- Cholesterol Metabolism Is Affected by Calcium Phosphate Supplementation in Humans -- @Rafael Lao Wai
That's Raj's finding.That adds a whole new dimension to "cleaning the gut" what do you think will be the effect of these fatty acid soaps (with regard to endotoxin)?
That's Raj's finding.
It must be part of the reason why I haven't been finding fat experiments as interesting. You can have the same fatty acid composition in two different meals and their effect can be quite different. And even if they're not, applying it in practice translates into selecting your foods based on 'theoresical nutrition' (Peat, 2010) and we know that this usually doesn't end up well. We might switch fats but lose a lot of valuable nutrients that were packed with it along.
But boring poetry aside, have you read this post?
- Why Ray Recommends Eating Lots Of Calcium
It would be great to know if those minerals are capable of complexing with the lipids of endotoxins to prevent their adsorption. From what I read, it's common for them to be saturated fats having chains of 10-14 carbons. Perhaps it's possible and they is fine candidates, but I'm not sure.

..and more:Calcium activates the enzyme pyruvate dehydrogenase (PDH)
In calcium homeostasis 1,25-(OH)2D works in conjunction with parathyroid hormone (PTH) to produce its beneficial effects on the plasma levels of ionised calcium and phosphate (5, 13). The physiologic loop (Figure 10) starts with calcium sensing by the calcium receptor of the parathyroid gland (14). When the level of ionised calcium in plasma falls, PTH is secreted by the parathyroid gland and stimulates the tightly regulated renal enzyme 25-OH-D-1-aa-hydroxylase to make more 1,25-(OH)2D from the large circulating pool of 25-OH-D. The resulting increase in 1,25-(OH)2D (with the rise in PTH) causes an increase in calcium transport within the intestine, bone, and kidney. All these events raise plasma calcium levels back to normal, that in turn is sensed by the calcium receptor of the parathyroid gland. The further secretion of PTH is turned off not only by the feedback action of calcium, but also by a short feedback loop involving 1,25-(OH)2D directly suppressing PTH synthesis in the parathyroid gland (not shown in figure).
Although this model oversimplifies the events involved in calcium homeostasis it is easy to see from it that sufficient 25-OH-D must be available to provide adequate 1,25-(OH)2D synthesis and hence an adequate level of plasma calcium and that vitamin D deficiency will result in inadequate 25-OH-D and 1,25-(OH)2D synthesis, inadequate calcium homeostasis, and a constantly elevated PTH level (termed: secondary hyperparathyroidism).
