Rickets was a disease that had almost disappeared in the UK by the 1940's, but the number of cases has risen rapidly over the last 15 years.
Health campaigners say this is evidence that people are not getting enough vitamin D and have voiced concerns that there will also be an increase in related diseases.
Key Findings - Fluoride & Rickets:
1) It is well documented - from human clinical trials, animal studies, and research on humans with skeletal fluorosis - that fluoride may cause osteomalacia. When osteomalacia is present during childhood, it is referred to as rickets.
2) An increased prevalence of rickets has been observed among children living in areas with high levels of fluoride in water, including in the USA in the 1930s, and among animals treated with high levels of fluoride...
Excerpts from the Scientific Literature: Fluoride & Rickets
"The findings strongly suggest that children with calcium deficiency rickets reported in the literature should be re-investigated for possible fluoride interactions... This aspect has not been analysed in any of the reports published on calcium deficiency rickets. A greater index of clinical acumen is, therefore, necessary to differentiate calcium disorders in childhood from fluoride and calcium interaction syndromes of bone disease and deformities..."

"During our field studies our attention was drawn to the high incidence of bone disease and bony leg deformities with clinical invalidism in children exposed to high intake of endemic fluoride in drinking water. Due to variable and unusual clinical features, these children had often been mistaken for rickets, renal osteodystrophy, osteosclerosis and hereditary osteopathies etc."

"Three children demonstrated some features resembling rickets in the form of fraying of metaphyses and apparent widening of the epiphyseal cartilage. These patients also had subperiosteal resorption of phalanges...A rickets-like picture may be a manifestation of the mineralization defects induced by fluoride toxicity..."

"Vitamin D should be given for floride rickets..."
VITAMIN supplements are being introduced in Blackburn with Darwen after 56 cases of rickets have been revealed.
Almost all the 56 cases found between 2003 and 2005 were in Blackburn with Darwen's South Asian community.
Experts said vitamin D, which is unique in being produced primarily by exposure to sunlight, was a relatively common deficiency among Asian immigrants, because of their darker skin, and Islam's requirements for clothing to cover limbs.
Dr Friedman said the problem was linked to cultural factors, not deprivation.
He said: "Once you exclude a number of vary rare cases where there is some other underlying condition, virtually every case is someone from the Asian community.
"It is caused by a combination of skin colouration, diet and dress, not poverty. We don't, for example, find rickets in deprived white communities."
inadequate sunlight exposure
Living in latitudes above 40º north or south, or cultural requirements to cover the skin, reduce synthesis of colecalciferol by the skin. Increased sunscreen use has also been implicated.
FHx of rickets
A family history of short stature, orthopaedic abnormalities, poor dentition, alopecia, and parental consanguinity may signify inherited rickets.
calcium deficiency
Inadequate intake of calcium can lead to insufficient bone mineralisation. Breast milk contains limited amounts of calcium, but cows' milk is a richer source. In societies without a tradition of milk-drinking, calcium intake is often
Dermatologists routinely talk of the need to wear sunscreen. But the body needs sunlight to produce vitamin D, a crucial nutrient.
So is it possible that wearing sunscreen might interfere with the synthesis of vitamin D?
Yes. Studies have found that by blocking ultraviolet rays, sunscreen limits the vitamin D we produce. But the question is to what extent.
A few studies have concluded that the effect is significant — a reduction as great as tenfold. But more recent, randomized studies that followed people for months and in some cases years suggest that the effect is negligible. While sunscreen does hamper vitamin D production, these studies say, it is not enough to cause a deficiency.
That is in part because most people typically do not apply enough sunscreen to get its full effects, which in turn allows some sunlight through, said Dr. Henry Lim, chairman of dermatology at the Henry Ford Hospital in Detroit and a spokesman for the American Academy of Dermatology. And according to the National Institutes of Health, it does not take much sunlight to produce adequate amounts of vitamin D: perhaps as little as 30 minutes of daytime exposure (without sunscreen) twice a week.
Dr. Lim added that rather than cutting back on sunscreen, people concerned about vitamin D should consume more foods rich in vitamin D, like salmon, milk and orange juice.
THE BOTTOM LINE
Sunscreen can reduce vitamin D production, but probably not enough to have a significant effect.

Chemical suncreans lead to cancer and cause vitamin D deficiency, even taking a shower right after being exposed to the sun can wash off the vitamin D that's trying to absorb into your skin.
I take a vitamin D3 supplement daily to prevent disease from lack of sunlight.....

One of the potential consequences of people spending too much time indoors is lack of exposure to sunlight, leading to vitamin D deficiency, and, quite shockingly in this day and age, rickets.

Lack of vitamin D can also be associated with the development of multiple sclerosis, diabetes, osteoporosis, arthritis, heart disease and even cancer.
Fear of over-exposure to sunlight / UV rays and the consequent overuse of suncream may well be a contributing factor, not to mention the sedentary life-style. Yet more evidence a more 'natural' life-style is what benefits the human body! (Meantime expect health messages promoting a near hysterical fear of sunlight to continue...)
