Can Higher Vitamin D Levels Lower Cancer Risk?
Vitamin D3 has been shown to play a role in the prevention and treatment of breast and colon cancer, osteoporosis, dementia, PCOS, depression, chronic pain and so much more! Vitamin D deficiency is a worldwide health problem. The major source of vitamin D for most of us is sensible sun exposure.
What is vitamin D?
Vitamin D is important for good overall health, strong bones and healthy teeth. It’s also an important factor in making sure your muscles, heart, lungs and brain work well and that your body can fight infection. Your body can make its own vitamin D from sunlight. You can also get vitamin D from supplements, like Lorna Vanderhaeghe Vitamin D3 Droplets, and a very small amount comes from a few foods we consume.
The vitamin D that we get in our skin from sunlight, and the vitamin D from supplements, has to be changed by the body a number of times before it can be used. Once it’s ready, the body uses it to manage the amount of calcium in the blood, bones, and gut and to help cells all over the body to communicate properly.
The link between vitamin D and strong healthy bones was made many years ago when doctors realized that sunlight, which allows us to produce vitamin D, or taking cod liver oil, which contains vitamin D, helped to prevent a bone condition called rickets in children. Today, vitamin D is seen as a vital part of good health and it’s important not just for the health of our bones. Recent research is now showing that vitamin D may be important in preventing and treating a number of serious long-term health problems, including cancer.
Cancer, sunlight and vitamin D.
According to a study released in the Journal of Clinical & Translational Endocrinology, ‘The sunshine vitamin has been associated with reduced risk for many chronic illnesses including cancer and cancer mortality. Epidemiologic and ecological studies have suggested that living at higher latitudes and having lower blood levels of 25-hydroxyvitamin D are associated with increased risk for up to 15 cancers including breast, colon, lung, lymphoma, pancreatic, ovarian and prostate cancer.’
There are two main sources of vitamin D and two major forms of vitamin D. During sun exposure the precursor of cholesterol, 7-dehydrocholesterol, in the upper and lower layers of the skin absorb solar ultraviolet B radiation (290–315 nm) and is then converted to pre-vitamin D3. Once formed pre-vitamin D3 changes in the arrangement of its double bonds to form vitamin D3 which then exits the plasma membrane of the skin cells into the outer space surrounding blood vessels. It diffuses into the dermal capillary bed for transport to the liver. Vitamin D3 is also found in oily fish, cod liver oil and fortified foods such as dairy products, margarine, cereals, and some juice products as well as in supplements, like Lorna Vanderhaeghe Vitamin D3 Droplets and Natural Factors Vitamin D3 Drops for Kids.
Avoiding the sun may be as dangerous as smoking cigarettes!
In the last several decades, the push to use sunscreen and limit exposure to the sun has gotten stronger. Nowadays it is possible to find SPF 70 or higher! Thanks to huge campaigns, most people are at least mildly aware of the “dangers” of sun exposure. Here’s where things get interesting…sun exposure may not be as dangerous as we think! And avoiding the sun may be the dangerous part. A recent in-depth scientific review found that while sunburn is harmful, moderate non-burning sun exposure (without sunscreen) had many benefits.
The general consensus is that since sunscreen prevents sunburn, it also ‘logically’ prevents skin cancer. Of course, this seems logical, but science doesn’t back this up! Sunscreen may block some of the most beneficial aspects of sun exposure. It may slow burning, but it also blocks Vitamin D, and vitamin D deficiency is epidemic.
The most comprehensive current studies don’t recommend avoiding the sun. To the contrary, the recent review (read the full review here) concluded:
“In this paper we review the current state of the science of the risks and benefits of sun exposure and suggest that public health advice be changed to recommend that all men, women, and children accumulate sufficient non-burning sun exposure to maintain their serum 25 hydroxyvitamin D [25(OH)D] levels at 30 ng/mL or more year-round.”
According to Jessica Jaymes, health consultant at Yes Wellness – “As with anything, moderation is key – use a natural sunscreen for extended periods of sun exposure, supplement Vitamin D into your diet, eat healthy colorful meals and you’ll be well on your way to your healthiest YOU yet!”
