Vitamin D: the “Sunshine” Vitamin Rickets could also be a disease of the bones which affects children and is caused by insufficient bone mineralization during growth: as a result, bones weaken and bow under the body weight’s pressure. Before the seventeenth century, rickets was an almost unknown disease. But soon after the commercial revolution, with its huge problems of pollution in urban areas, the incidence of this disease skyrocketed.
It took scientists almost two centuries to figure out that the two things were connected: somehow, it had been exposed to sunlight that was able to prevent the onset of rickets. Towards the beginning of the 20th century, scientists realized that if a toddler with rickets is exposed to the sunshine of a UV lamp, the disease will regress.
it absolutely was clear however that light did not act directly on bones, because when a toddler was exposed to the UV light on just one arm, the disease regressed in an identical way within the opposite arm still. Clearly, exposure to sunlight, or the light of a UV lamp, was able to induce within the skin the assembly of an anti-ticket element, that could subsequently be carried to the rest of the body.
Unfortunately, the number of air pollution following the economic revolution was vitamin D: the “Sunshine” Vitamin high that the smoke generated from the factories would filter most of the sunshine coming from the sun, especially in urban areas, causing the above-mentioned spike in rickets cases in children.
Nevertheless, a winning strategy to cure tickets had already been discovered one century before by professor Bretonneau and had nothing to do with sunlight. Rather, it had been cod liver oil. When administered to cricket patients, it caused the disease to disappear, incredibly fast. How was it possible that two so different strategies – exposure to sunlight or eating oil – were both able to independently care for rickets?
It wasn’t until 1920 that scientists were able to figure it out, by identifying the wonder molecule that’s contained in cod liver oil: it had been called a vitamin, or cholecalciferol. This very same molecule is additionally the “antiricketelement” that’s inbuilt our own skin when it’s exposed to sunlight.
But if a deficiency of ergocalciferol in children seriously impairs mineralization or the growing bones, resulting in rickets, it’s just as detrimental in adults and even more in older adults, causing a painful reduction in bone mineralization, called osteomalacia, moreover as promoting osteoporosis, a weakening of bone vitamin d mineral structures that make them extremely fragile and at risk of fractures.
For identical reasons, many people suffer from seasonal back pains, joints, and muscle pains, often confused with arthritis. Oftentimes, a sterol supplement would be enough to create these ailments go away. But why is sterol so vitamin D important for the health of our bones? the foremost task of cholecalciferol is maintaining adequate concentrations of calcium and phosphorous in our bloodstream, which successively ensures an adequate supply for the mineralization of our bones.
Vitamin D ergocalciferol accomplishes that in two different ways: first, by regulating natural phenomena in our intestine, it stimulates the production of those proteins that are necessary to take in calcium. Second, in our kidneys, sterol stimulates reabsorption of calcium and phosphorous, preventing them from being lost with our urine.
These two mechanisms all cause the same effect: our blood concentrations of calcium and phosphorous raise. Keeping their concentrations stable is vital for our own survival, as they’re necessary so our heart can beat and nerve impulses can be transmitted. Of course, ergocalciferol is critical only when blood levels of calcium and phosphorous are low, but we don’t must worry about this.
vitamin by itself is inactive. When it is necessary, our body takes the necessary steps to activate it so it can become a brisk hormone, called calcitriol, and perform its important functions. Vitamin D Active ergocalciferol is so powerful that its activation is very strictly regulated, and it needs two different consecutive steps as if you needed two different keys to open a secure box. the first activation step takes place in our lives, the second in our kidneys.
this implies that getting many vitamin D from food, sunlight exposure, or supplements, doesn’t automatically cause inducing its hormonal activity if that’s not necessary. It just means giving our body the opportunity of doing so, should the need arise. the vitamin is an implausible molecule that never ends to surprise researchers.
it is a hot topic in nutrition, Vitamin d it’s still actively researched, which we keep searching for more and more fascinating things about this powerful molecule. First of all, active cholecalciferol includes an awfully strong anti-cancer activity, by inhibiting cell proliferation and promoting cell differentiation. Numerous epidemiological studies have associated low D with an increased incidence of cancers, especially breast, colon, prostate, and ovarian cancers.
Vitamin d calciferol exerts an awfully important regulatory activity on our system and its deficiency has been associated with increased risk for disease, including type I diabetes and sclerosis. So far, we’ve identified about fifty genes whose expression is regulated by D. some years ago, it’s attracted plenty of interest the role of cholecalciferol in raising serotonin levels, which improve our mood, thus making it a sort of natural antidepressant.
During menopause, ergocalciferol and calcium supplements are often beneficial in controlling a variety of unpleasant symptoms, like hot flashes and irritability. By inhibiting the excessive secretion of renin from our kidneys, D also helps control pressure and avoid hypertension of renal origin.
Marginal deficiencies of calciferol are associated with increased risk for acute cardiovascular events, like heart attacks and strokes. The list could persist and on, but I think I gave you an inspiration of what percentage of various things this powerful molecule can accomplish.
Food sources of D are rather limited. in need of eating fish liver oil, the foremost effective source is eating small fishes that you just simply can eat whole, including their livers, like sardines. Fatty fish, like salmon or herrings, even have more vitamins because they store some in their animal tissue.
