Optimised supply of vitamin D prevents dental cavitiesVeldhoven, 9 August 2011 (SRF) The risk of developing cavities can be significantly reduced through the optimised supply of vitamin D. A vitamin D level of at least 30 nanogrammes per millilitre of blood (30 ng/ml) encourages the body to produce its own anti-microbial peptides, including cathelicidins and defensins, which inhibit cavity pathogens. This was the result of a study carried out by William B. Grant, one of the best known experts worldwide in the field of vitamin D research, and presented in the professional journal “Dermato-Endocrinology“.
In this study in the USA, Grant evaluated 325 scientific studies covering a period from the middle of the 19th century to today and which prove the connection between the intensity of UV radiation and the formation of cavities. Grant explains the relationship as follows: “Cavities are significantly more common in geographical regions with lower levels of UV radiation intensity than in regions with higher levels. UV radiation encourages the production of vitamin D and vitamin D in turn is the motor for producing anti-microbial peptides which prevent cavities from forming”. Grant recommends placing greater emphasis of an optimised supply of vitamin D in dental prophylaxis.
Vitamin D production is stimulated by UV radiation with 90 percent of it being produced in the skin. An average vitamin D level of at least 30 nanogrammes per millilitre of blood (30 ng/ml) is generally considered by experts to be the value at which the positive effects of vitamin D are seen. Values between 40 and 60 ng/ml are considered optimal.

The Sunlight Research Forum (SRF) is a not-for-profit organisation based in The Netherlands. SRF’s aim is to help bring to the fore, the latest medical and scientific information on the effects of moderate UV exposure on man. It takes time, often decades, for new scientific ideas to be accepted and assimilated, first into the general body of scientific knowledge and finally into policy. We want to reduce this time to a minimum so that the benefits of research can lead to a better understanding of UV effects on man and will become available to the public without any unnecessary delay. We hope to provide policy makers with correct information on which to base national health policy and individuals with better information on which to base choices about their lifestyles.
New research and well founded ideas on moderate UV exposure both indoor and outdoor will be presented and discussed in the Sunlight Research Forum by people working in the health disciplines, by academics and by journalists.

Sunshine vitamin boosts fertility
A study reveals that the higher the vitamin D level, the greater the chance of pregnancy following artificial insemination An optimum supply of vitamin D is one of the success factors for so-called in-vitro fertilisation, artificial insemination in a test tube. The results of a scientific study by the Faculty of Medicine at Kocaeli University in Turkey reveal that the higher the concentration of vitamin D in the follicular fluid surrounding

Attested by a study among 70.000 women: the crucial aspect is sufficient UVB radiation; diet or food supplements merely have a supporting function. Regular sun exposure and a vitamin D-rich diet reduce the risk of developing breast cancer by around 32 to 43 percent. The deciding factor in prevention is exposure to adequate UVB rays. Admittedly food that is rich in vitamin D, such as fish, dairy products, eggs and certain
Sperm switch into top gear with the sun
Veldhoven, 19 May 2011 (SRF) Men who top up on vitamin D in the sun or in a solarium, give their sperm an advantage in terms of motility, speed and penetration force. This was the conclusion of a study conducted by scientists from the University of Copenhagen investigating the role of vitamin D in human sperm production. The scientists tested the quality of sperm from 300 men chosen at random and
Tanning provides greater protection from the sun
Veldhoven, 10 May 2011 (SRF). Allowing the skin to slowly become accustomed to UV radiation from sunlight by moderate tanning creates a protective effect. Studies repeatedly find that continuous sun exposure below the erythema threshold (when the skin begins to redden) is essential in helping the human body to build up its natural self-protection mechanism against UV ray overexposure. Pigmentation and the formation of the so-called “light callous” - a
