I've been wanting to post something on Vitamin A deficiency and how it may be affecting our health and even hindering progress in healing.
I keep forgetting however where I found the information that I wanted to address so I'm going to do my forgetful best, to compile some of the info here and tell me what you think.
First read this:
Vitamin A in Adrenal Hormone and Mucopolysaccharide Biosynthesis
GEORGE WOLF D. PHIL.1

Vitamin A deficiency was found to cause an abnormal metabolism of acetate, and reduced glyconeogenesis. This was traced to a malfunction of the adrenal cortex and, ultimately, to an interruption of adrenal glucocorticoid hormone (corticosterone) biosynthesis in the vitamin A deficient rat. In adrenal cortex homogenates from vitamin A deficient animals, the reduced corticosteroid biosynthesis could be restored to normal by adding vitamin A or vitamin A acid in vitro. The influence of the vitamin on one of the enzymes of corticosteroid biosynthesis seems, therefore, to be a direct one.
Another lesion caused by vitamin A deficiency, the degeneration of mucous membranes, was found to be due to a requirement for vitamin A in mucopolysaccharide biosynthesis. This was shown by lowered incorporation of labeled sulfate or glucose into mucopolysaccharide in rat colon homogenates, restorable specifically by added vitamin A. Similarly, net synthesis of mucopolysaccharides in rat colon homogenates, as measured by an increase in mucopolysaccharide-bound hexosamines, is partially dependent on vitamin A. This effect was traced to an enzyme fraction and finally to a single reaction in the biosynthesis of mucopolysaccharide, the activation of sulfate to form adenosine phosphosulfate.
Second, I read a little while back that our adrenals could not make the hormones that it needed without Vitamin A. Now a good portion, if not all of us, have to be deficient in this vitamin. The reason I say this is that our adrenals affect our thyroids and without proper thyroid function your thyroid can not convert beta carotene into vitamin A you will also have this problem if you have diabetes. Second, even if you are eating plenty of eggs and butter you may need liver or codliver oil because when the body is ill or stressed (and that is what our condition is, is chronic stress) it quickly depletes the Vitamin A stores.
Thankfully, I finally found an article today that pretty much said the same thing that I had read a while back.
This is an excerpt but you can follow the link to read the entire article: http://www.westonaprice.org/ask-the-doctor/228-steroid-drugs.html
"To do this, we refer to some basic physiology. First, we are dealing with the adrenal cortex, not the medulla (which makes adrenaline). The hormones that the adrenal cortex makes are all derived from our best friend--cholesterol. Yes, cholesterol is the precursor to all the valuable adrenal hormones that help us deal with stress, inflammation and trauma, and that help our body to heal. Therefore adrenal insufficiency (lack of adrenal cortical hormones) is a fat deficiency. So the first step is and logical: eat more fat, especially cholesterol-rich animal fat. One of these fats should be cod liver oil to supply vitamin A. The adrenal cortex cannot make adrenal hormones out of cholesterol without vitamin A."
I found some more info on Vitamin A and how it relates to the hippocampus. So I'll be back soon and finish my article.
