B12 DEFICIENCY - Why It Matters
Once nearly unheard of in "wealthy" countries this deficiency was relegated primarily to third world countries - due to diet. Now Vitamin B12 deficiency is firmly on the radar of the medical establishment. Skyrocketing rates in the wealthier countries and reaching 50% in certain sub-dietary categories. And why does B12 matter?
The symptoms of sub-clinical B12 deficiency are subtle and often not recognized. The long-term consequences of B12 deficiency may include adverse effects on pregnancy outcomes, vascular, cognitive, bone and eye health.
Severe vitamin B12 deficiency is linked to neurological disorders and can lead to deep depression, paranoia and delusions, memory loss, incontinence, loss of taste and smell, and more.
"Vitamin A" is actually a reference to several related nutrients that can be divided up into two main categories:
- Retinoids (aka retinol), the bioavailable forms of vitamin A found in animal foods
- Carotenoids, previtamin A found in plant foods
Retinol, found in animal foods like liver, meat, bone broth and eggs is the type of Vitamin A our body can readily absorb. Eating carotenoids (pre-vitamin A) from plant sources, your body must convert the carotenoids into bioavailable retinol. If your the picture of health this shouldn't be a problem.
However, a number of factors can inhibit your body's ability to absorb carotenoids and convert them into retinol (Vitamin A).
This includes genetics, digestive problems, alcohol use, certain medicines, toxic exposures, and medical conditions that interfere with the digestion of fat (including Crohn's disease, pancreatic enzyme deficiency, and gallbladder and liver disease).
In a majority of people, the carotene-to-retinol conversion is severely compromised, and in some it may be quite negligible. This is particularly true for infants, diabetics, and those with compromised bile production. Did you know that Vitamin A is a strong antidote for the measles and many other childhood diseases.
Additionally, the body's ability to convert carotenoids into bioavailable vitamin A depends on your diet. If you're on a low-fat diet, your conversion rate is virtually guaranteed to be inadequate.
While carotenoids are water-soluble, you still need healthy fats to promote efficient conversion of carotenoids to retinol. As explained in one 2004 study:
"[P]rovitamin A carotenoids are converted to retinal by beta-carotene-15,15'-dioxygenase. The enzyme activity is expressed specifically in intestinal epithelium and in liver.
The intestinal enzyme not only plays an important role in providing animals with vitamin A, but also determines whether provitamin A carotenoids are converted to vitamin A or circulated in the body as intact carotenoids.
We have found that a high fat diet enhanced the beta-carotene dioxygenase activity together with the cellular retinol binding protein type II level in rat intestines...
Thus, the bioavailability of dietary provitamin A carotenoids might be modulated by the other food components ingested." Journal of Nutrition: https://www.ncbi.nlm.nih.gov/pubmed/14704326
So, what food or foods can help provide a high quality Vitamin A and Vitamin B. We know beef liver is one. And bone broth, especially a bone broth such as Best of the Bone which is higher in marrow and collagen and essential fatty acids. Those fatty acids increase the absorption of the fat soluble nutrients and micronutrients in your diet.go too www.theherbaldoctors.com/products for more information.
