Vitamine D tegen borstkanker*
Uit een studie onder ruim 6.500 deelnemers, waarvan bijna de helft borstkankerpatiënten en de andere helft gezonde vrouwen, blijkt dat zelfs een lage dagelijkse dosis vitamine D de kans op borstkanker al doet dalen. Vrouwen die 10 mcg vitamine D per dag nemen blijken 24% minder kans op borstkanker te hebben.
Even a low-dose vitamin D pill cuts breast cancer risk by 24 percent
A recent research study on vitamin D has shown that even low-dose vitamin D supplementation plays a big role in preventing breast cancer. According to the study, which was published in the American Journal of Clinical Nutrition, women who take at least 400 international units (IU) of vitamin D a day lower their risk of developing breast cancer by 24 percent.
Over 6,500 patients participated in the study, which study authors believe points to vitamin D's ability to regulate and control the growth and spread of malignant cancer cells. According to Laura Anderson, one of the study authors, breast cells have their own receptors for vitamin D, so it makes perfect sense that vitamin D exerts a positive influence on the body in terms of warding off cancer.
Several other recent studies have also shown a definitive link between vitamin D intake and decreased cancer risk, highlighting this nutrient's powerful health-promoting and disease-preventing capabilities.
The research team also noted that vitamin D assimilates very well when coupled with calcium, and vice versa. The two vitamins work in tandem for maximum absorption of both in the body, so it is important to get plenty of both.
And although it was not specifically mentioned in the report, vitamin D is easily obtained through natural sunlight exposure. Your skin is fully capable of absorbing sunlight and processing it into vitamin D. In fact, just 15 to 30 minutes of exposure a day during the warmer months will ensure that you get the maximum amount of vitamin D for maintaining optimal health, without the need for a supplement.
During the winter months when sunlight exposure is limited, you can supplement with natural vitamin D3 as an alternative. It will effectively achieve the same results as if you were getting natural sunlight, however natural sunlight is preferable when available.
The governmental recommended daily intake of vitamin D is a mere 400 IU for adults, which many now consider to be far too low. To get a significant therapeutic effect from vitamin D, dosages upwards of 10,000 IU a day are far more appropriate. Because the body absorbs roughly 20,000 IU from the sun before shutting off for the day, it is safe to assume that supplementing with vitamin D3 in roughly this amount is safe as well. (November 2010)
