Vitamin B12 and protein metabolismdoes it make a difference if it's coming from diet (and consumed along with the methionine meal) or if it's being drawn from the reserves (and later replenished)?

I forgot to add that there are two problems in leaving it immersed in citrus juice: deterioration of nutrients and toughening of the protein.Now since this thread is about minimizing the potential problems with cheese, if you find a fresh one that is good but too salty, you can just soak it in lime water for some time and it works like a charm. Some string cheeses for example can be salted in excess, and if you consume a lot, the salt can add up.
Consuming some carotene-rich fruits (papaya, mango, etc) along with low-fat cheese might not be a bad idea.That's pretty important, so I guess people who do a lowish fat diet with a decent amount of proteins should supplement fat solubles, besides liver I don't know what he considers as rich sources of retinol from proteiny foods, yolks maybe.
Most certainly. I think cheese is best consumed grated over finely-cut kale and eaten with chopstix. I feel this tends to equalize both the Ca²⁺∶Mg²⁺ ratio and the Na⁺∶K⁺ ratio.Consuming some carotene-rich fruits (papaya, mango, etc) along with low-fat cheese might not be a bad idea.
Travisord used to consume cheese with leafy greens, taking care of vitamins A and K. The same applies to meals with meat where greens can be flavored with butter: beet greens, spinach, etc. For carotene, some cooked carrots, sweet potato, pell bepper, pumpkin, etc.
If supplementation is needed, I doubt a lot is required. Taurine can be used to stimulate bile release in the ad sense of enough fat.
Good information, Chris masterjohn has some really good research on the fat-soluble vitamins.https://www.westonaprice.org/health-topics/abcs-of-nutrition/the-problem-with-protein/
"PROTEIN AND VITAMIN A
We need look no further than Chris Masterjohn’s article, “Vitamin A, The Forgotten Bodybuilding Nutrient” (Wise Traditions, Fall 2004). As Masterjohn explains, “The utilization of protein requires vitamin A. Several animal studies have shown that liver reserves of vitamin A are depleted by a high dietary intake of protein, while vitamin A increases in non-liver tissues. One explanation for this is that adequate protein is necessary for vitamin A transport. In one study, researchers fed radioactively-labeled vitamin A to rats on low-protein and high-protein diets, using the amount of radioactivity present in exhaled gases, urine and feces as a measure of the metabolism of vitamin A, and found that vitamin A is indeed used at a higher rate on a high-protein diet.”
Masterjohn continues, “Vitamin A is not only depleted by a high intake of protein, but it is also necessary for the synthesis of new protein, which is the goal of the bodybuilder. Rats fed diets deficient in vitamin A synthesize protein at a lower rate than rats fed adequate vitamin A. Cultured skeletal muscle cells increase the amount of protein per cell when exposed to vitamin A and D, but not when exposed to vitamin D alone.”
In other words, eating lean meat or taking a protein powder sends a signal to the liver: “Send me vitamin A!” Protein consumed in the absence of fat, with its precious cargo of fat-soluble vitamins, including vitamin A, is an effective way of rapidly depleting your liver of vitamin A stores.
What happens when the liver becomes depleted of vitamin A, so that none can be made available to the body when needed?
Vitamin A is key to almost every process in the body—the concert master, so to speak—not only for protein synthesis, but also for hormone production (including sex hormones like testosterone, and thyroid hormone); vitamin A is also key to immune system function, critical for healthy vision and hearing, plays a role in bone health, and works in tandem with vitamins D and K2 for everything from the prevention of heart disease to the production of feel-good chemicals. A diet of lean meat, or one that incorporates protein powders, is a recipe for hormone disruption, fatigue, depression, bone problems, auto-immune disease, vision and hearing problems, heart disease and even cancer."
I'm sure the same can occur with cheese if the person isn't getting enough vitamin A elsewhere.
Effects of vitamin C and vitamin D interaction on the performance, immunity, and bone characteristics of commercial broilers
"Vitamin C is reported to reduce plasma corticosterone, a stress hormone, and the heterophil:lymphocyte (H:L) ratio. Sergeev et al. [9] reported first that VC plays a critical role in VD metabolism and binding in guinea pigs. Their study strongly suggested that VC affects the vitamin D endocrine system both at the level of 1,25-dihydroxycholecalciferol [1,25-(OH)2D3] formation in kidneys and its receptor binding in the target tissue. Their further research has demonstrated that in VC-deficient guinea pigs, serum 25-hydroxycholecalciferol (25-OHD3) and receptor concentrations for 1,25-(OH)2D3 in the intestinal mucosa are significantly decreased.
Vitamin C is required for the conversion of VD into its metabolite form calcitrol, which is essential for calcium regulation and the calcification process [10]. Vitamin C is required for hydroxylation of proline residues necessary for the synthesis of procollagen, which is a precursor to bone formation. Vitamin C has been reported to improve leg bone conditions in stressed birds. Because birds synthesize their own VC, the role of exogenous VC is still unclear in collagen synthesis. The conversion of 25(OH)D3 to 1,25(OH)D3 and 24,25(OH)D3 is dependent on the supply of VC [11]. Farquhsarson et al. [12] reported reduced incidence of tibial dyschondroplasia in broilers (40 to 11%) when the diet was supplemented with VC. Supplements of 1,25(OH)D3 completely eliminated tibial dyschondroplasia. In these studies, supplements of ascorbic acid and 1,25(OH)2D3 had the same effect on some key bone resorption marker enzymes."
What?! 1gram can make a lot of difference?? When did you see the dark side?Supplementing is definitely better than becoming deficient and 1g can make a lot of difference. But sometimes a supplement can be useful just for the sake of testing.
To define what an excess of calcium and sodium is I guess we should venture away from Peat. Do you have any idea what the excess is? From what I gathered among quality members of the forums, potassium/sodium and magnesium/calcium and calcium/phosphorus ratios would be important, but does that mean they are the only reliably way to kantify what an excess is and that no amount is by definition too much?Casein indigestion is not uncommon (hence the effects of opioids*), and if the diet has an excess of calcium and sodium, this combination can make the vit C situation worse; deranged calcification is a clue (also some sort of sub and clinical scurvy).
*there is some discussion on 'bcm7 (affecting) antioxidants' if you search for it.
gbolduev used to stress that whenever there's not enough proteid (such as casein the indigestion that I think I experienced a few times), the body will catabolize itself, and prioritize some parts at the expense of others. This process strains the adrenals of the glands requiring extra vit C.

I guess the only practical way of knowing if things are on the right track is through perceiving how the body is reacting.To define what an excess of calcium and sodium is I guess we should venture away from Peat.

This is of course interesting given the talk there has been on not only the opioids effects of certain proteins, but also the putrefaction from within. That does make me curious about the use of supplementing various protease in a healing phase. My bro-bro is on the way so I'll see how well it works, but generally digestive enzymes or even things like thiamine/betaine HCL could be worth looking into to help the body rebuild itself (e.g. tolerate gelatin and use the glycine in it). BCAAs, potatoes juice and other blends of amino/keto-acids could be worth considering as well.
However! He also included digestive enzymes in his protocol. I enjoy quoting him because he worked with debilitated people and developed a successful regimen through experimentation."After six to twelve weeks, animal proteins are added in the form of pot cheese (saltless and creamless), yoghurt made from skimmed milk, and buttermilk."
"Cultured dairy proteins (yoghurt & pot cheese) should be added at (not before) the sixth to eighth week according to the physician's judgement (pp. 80, 145, 146, 235). Exception: use churned, not cultured buttermilk."
