Scientists have found a promising link between vitamin D and breast cancer, with the vitamin shown to reduce breast cancer risk. However, they say their findings only apply to vitamin D in supplement form, according to Reuters.
Link Shown Between Vitamin D and Breast Cancer Risk Reduction
Researchers found that women who consumed vitamin D in a pill had a 24 percent lower risk of developing breast cancer. But those who got their vitamin D in their food didn’t see the same results. While they don’t say why they think this is, it could be because those using supplements are simply getting more of the vitamin on a daily basis.
The study, published in the American Journal of Clinical Nutrition, looked at 3,101 breast cancer patients and 3,471 health women, analyzing their diet and supplementation habits. There was no link established between dietary vitamin D consumption (or calcium consumption) and breast cancer. The link was only obvious in women taking more than 400 IU (international units) of vitamin D every day.
The researchers say more work is needed to determine exactly how much vitamin D is needed and to determine how it works. However, we do know that breast tissue cells have receptors for vitamin D, “raising the possibility that the nutrient could help regulate the division and proliferation of these cells.” And while the researchers don’t draw a connection between vitamin D and breast cancer when the vitamin comes from food sources, including the vitamin in a diet for breast cancer patients via foods naturally rich in vitamin D in addition to supplementation will only boost prevention.
Interestingly, the research gives no attention to getting vitamin D from the sun. It’s estimated that the body of the average light-skinned person creates about 20,000 IU of vitamin D3 (the most concentrated form) after one 30-minute, total body exposure to the summer sun at noon. In a darker skin person, the amount of D3 produced is about 10,000 IU.
You don’t need to sunbathe for hours to accumulate vitamin D, but getting outside for some sunshine during the day will increase the body’s natural creation of vitamin D, providing a wealth of vitamin D health benefits that could even reduce your risk of cancer.

[NaturalNews] “All skin cancer is the result of damage to skin cells,” says Lise Alschuler, ND, author of Five to Thrive: Your Cutting-Edge Cancer Prevention Plan.
Skin cell damage is caused by oxidative stress from free radicals, which manifests as sunburn. It’s the same process that causes metals to rust and apples to brown. Although oxidation cannot be completely avoided, oxidation must be minimized to avoid free radical damage.
Oxidative stress is both the cause and the consequence of disease. Contrary to what allopathic dermatologists recommend, a daily, moderate dose of sun without sunscreen is actually beneficial for the skin.
Bare skin exposed to direct sunshine boosts vitamin D3 production in your body, but it should be moderate. 20 minutes; three or four times a week during peak sunlight hours is sufficient for most vitamin D3 requirements. Then there are supplements that can be added as well.
Antioxidants are the key to reducing oxidative stress. Molecules with missing electrons are called oxidants; whose primary activity is replacing their missing electron by stealing an electron from another molecule. This, in turn, causes a molecular domino effect of oxidative stress that can lead to disease.
The magic of antioxidants is the well researched fact that they can donate an electron to an oxidant without in turn becoming a free radical. Antioxidants stop the cascading free radical effect and reduce free radical damage.
Minimizing free radical damage to skin cells can be boosted by the right diet. Eating lots of fresh, organic plant-based foods is the key. Plants thrive on sunlight while using their own flavonoids to protect them from excess oxidation. You can borrow those flavonoids by eating plants.
Other internal nutrients for your skin
A high quality multivitamin with the full spectrum of vitamin E (mixed tocopherols), mixed cartenoids and zinc would be helpful for maintaining healthy skin as well as, ironically, vitamin D3 supplements.
Good fats are important. Skin cells contain fats. Avoid processed trans-fatty oils and use cold pressed virgin olive or coconut oils for salads and cooking. Omega-3 fatty acids are critical for the full spectrum of health issues. Chia seeds, ground flax seeds, and uncontaminated fish oils are good sources of omega-3.

[NaturalNews] A study published in the journal Pediatrics found that 70 percent of U.S. children have low levels of vitamin D. “We expected the prevalence of vitamin D deficiency would be high, but the magnitude of the problem nationwide was shocking” says Dr. Juhi Kumar of Children’s Hospital at Montefiore Medical Center.
In times past it was known that not enough vitamin D caused a bone disease known as rickets, but more recent discoveries count vitamin D deficiency as a major factor in adult heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, at least 17 varieties of cancer and more.
Vitamin D deficiency has been noted in 69 percent of adult patients with inflammatory joint diseases or connective tissue diseases, 77 percent with soft tissue rheumatism, 62 percent with osteoarthritis, 75 percent with back pain, and 71 percent with osteoporosis.
The “sunshine” vitamin
Years ago it was wrongly proposed that the sun was our enemy and that sunshine caused skin cancer. Boy were we wrong! The opposite it true and our abuse of sunblock goops is growing in lock-step with the growing numbers for skin cancer.
The skin makes the best form of vitamin D from sun exposure and produces approximately 10,000 IU of vitamin D with just 20-30 minutes of full-body summer sun exposure. Sunlight exposure is the best way to get Vitamin D, as the body automatically regulates how much Vitamin D it makes from sunlight. The body stores vitamin D for up to six months.
Then there is the added benefit of vitamin D controlling cholesterol levels. Since vitamin D precursors require cholesterol for conversion, without adequate sun exposure, vitamin D precursors can turn into cholesterol instead of the vitamin. Conversely, statin drugs hamper the body’s vitamin D levels.
Vitamin D is essential for the absorption of calcium. A person deficient in vitamin D doesn’t absorb enough calcium, even if the intake of calcium is high. Vitamin D is also an anticancer miracle being part of a metabolic product called calcitriol that influences some 2,000 genes in the body. Vitamin D has also repeatedly shown great promise in fighting off colds and flu, and people who are D-deficient are more likely to get sick.
Where to get your vitamin D
The best source of vitamin D comes from the sun – which makes supplementing with cholecalciferol (D-3) pills second best. Being an oil-soluble vitamin, at least a portion D-3 should be from cod liver oil, so that some Vitamin A and other oils’ fractions are included. If you are taking a large daily dose of Vitamin D, divide the dose between two or three meals.
Diet sources of vitamin D are fatty fish and fish liver oils, mushrooms, eggs and raw milk. Some foods, such as milk and orange juice, are fortified with vitamin D, but the form of vitamin D used for fortification is not best.
Read your labels and definitely avoid the Big Pharma version called calcitrol vitamin D. Take too much synthetic vitamin D and you might just end up with muscle weakness, apathy, headache, anorexia, irritability, nausea, vomiting, and bone pain. Keep on taking too much and you could get constipation, anorexia, abdominal cramps, polydipsia, polyuria, backache, hyperlipidemia, and hypercalcemia.
A blood test can determine where your actual vitamin D levels are. The Vitamin D Council recommends blood levels between 50-80 ng/mL. Adults can safely supplement with D-3 in divided doses up to 10,000 IU a day. If you have cancer your naturopath may prescribe much more.
The American Academy of Pediatrics recently updated its vitamin D guidelines for infants, children, and teens to 400 IU per day in supplement form although many health experts say that amount is still far too low.

Go ahead: pack up a healthy lunch and step into the sun. Your brain will thank you for it. A study conducted by the University of Manchester proposes that adequate levels of vitamin D—which abounds in direct sunlight—helps maintain mind health and cognitive function. Researchers examined over 3,000 European men between the ages 40 and 79 and found that those with high levels of the vitamin outperformed with low levels in memory and information processing trials.
Dr. Iain Lange, who conducted similar research, warns that poor diet in general—not necessarily vitamin D deficiency—could be to blame for poor mental performance. Even so, he admits that the evidence for vitamin D is rising and that it may safeguard cells or signaling pathways in the brain.
Vitamin D Deficiency Effects Mind Health and More
Vitamin D deficiency is linked with rickets in children, weak bones in the elderly, poor mind health, heart disease, diabetes, and even cancer. A 2010 blog post in the Scientific American even adds to the ever extending list Parkinson’s disease, a neurological disorder associated with cognitive decline.
Many studies in recent years (using genetically modified mice, although who knows how they’ve been “modified”) report that the animals experienced premature aging—retarded growth, osteoporosis, atherosclerosis, immunological deficiency, skin and organ atrophy, and short lifespan—due to low levels of vitamin D.
Despite the mounting evidence, researchers are quiet about why vitamin D is linked with mind health and improved cognitive health – it’s because they simply don’t know.
Some say that vitamin D may trigger a boost in protective hormonal activity in the brain, although only animal and no human studies can back up this theory. Others claim that vitamin D reins in a hyperactive immune system. Still others cite the vitamin’s ability to boost antioxidant levels and detoxify the brain.
While still researching why vitamin D is such a boon, Prof. Tim Spector of King’s College London says, “This underscores the importance of vitamin D for humans and why evolution gave us a liking for the sun.”
And what better way to celebrate our evolutionary history than to slather on some SPF and step out into the great outdoors?
If you need more reasons to take that beach trip this year, check out our previous article on the amazing benefits of vitamin D. And for those days when you’re stuck inside (remember, vitamin D can’t penetrate window glass!), read up on other ways to get your fill of this essential nutrient.

[NaturalNews] Thousands of research studies have demonstrated the powerful health-promoting properties of the prohormone compound, vitamin D3. Researchers publishing in The Journal of Immunology explain the specific molecular and signaling events by which vitamin D inhibits inflammation in the human body. In a very detailed analysis, scientists show that low blood circulating levels of vitamin D do not adequately inhibit the inflammatory cascade necessary to turn off this potentially destructive mechanism.
Low levels of inflammation, normally used by the body to fight pathogenic invaders, become a primary cause of heart disease, diabetes, many cancer lines and Alzheimer’s dementia. Additional evidence reported in the British Journal of Nutrition demonstrates that adequate vitamin D levels reduce critical markers of cardiovascular health and can lead to significant reductions in body fat in overweight and obese people. It is critical to have your vitamin D level checked, and supplement as necessary to lower inflammation levels and risk of heart disease.
Vitamin D lowers inflammation to prevent chronic disease and stimulate immune response systems
Dr. Elena Goleva, lead scientist from National Jewish Health, found that prior studies with vitamin D show a clear and positive link between blood levels of the prohormone and a variety of different health outcomes. Dr. Goleva and her team looked for specific mechanisms to explain precisely how vitamin D functions at the cellular level to prevent disease in the human body.
Dr. Goleva and her team of researchers noted that vitamin D is a catalyst that initiates “a clear chain of cellular events, from the binding of DNA, through a specific signaling pathway, to the reduction of proteins known to trigger inflammation.” To test how vitamin D acts on immune and inflammatory pathways, team scientists exposed human white blood cells to varying levels of vitamin D and exposed them to an agent known to promote intense inflammatory responses and advance disease processes.
White blood cells that were incubated with no vitamin D or a solution of 15 ng/mL produced very high levels of the pro-inflammatory cytokines IL-6 and TNF-alpha. In vivo, these signaling messengers are known to be responsible for the development and progression of cardiovascular disease, certain forms of cancer and dementia. Cells incubated at a concentration of 30 ng/mL and above showed a significantly reduced response, while the highest level of inflammatory inhibition occurred at 50 ng/ml.
Supporting evidence for the health-promoting effect of vitamin D as reported in the journal BMJ shows marked improvement in cardiovascular biomarkers including HDL cholesterol. Additionally, researchers found the hormone-like substance lowered the risk of lipid peroxidation, the process responsible for making LDL cholesterol molecules sticky and prone to form atherosclerotic plaque. They also determined that high circulating levels of vitamin D were associated with “significant reductions in fat mass” in overweight and obese people.
There should be no doubt that the millions of people living with grossly sub-optimal vitamin D levels are dramatically increasing their risk of developing a plethora of potentially deadly illnesses. Health-minded individuals will ensure they maintain a circulating blood level of 50 to 70 ng/mL by means of a 25(OH)D blood test to regulate systemic inflammation and fight chronic disease.

[NaturalNews] Conventional wisdom holds that calcium and dairy products are needed for strong, healthy bones and teeth. However, recent research published in the Archives of Pediatrics & Adolescent Medicine shows that vitamin D intake may actually be the more essential nutrient for strong bones. The team of researchers, who hailed from various medical establishments in Boston, MA, followed over 6700 girls between 9 and 15 years of age from 1996-2001. The research was conducted via questionnaire sent at 12-24 month intervals, asking about dietary intake of calcium, dairy and vitamin D along with stress fracture incidence. It was found that while dairy and calcium intake was unrelated to the incidence of stress fractures, there was an inverse relationship between vitamin D intake and the occurrence of stress fractures. Those with a higher vitamin D intake had a lower risk of stress fractures.
Stress fractures are a common injury that plagues athletes, especially teenage girls. They are caused by high levels of pressure or stress on the bone and can sometimes develop over time, even without any noticeable injury. The scientists discovered that girls involved in more than one hour a day of a high stress activity were especially protected by vitamin D intake.
While it has long been known that severe Vitamin D deficiency results in rickets, a serious disease which prevents mineralization of the bones and results in skeletal deformities, it is now being discovered that less severe deficiencies can result in weaker bones that are more prone to stress and injury. Previous studies have shown that vitamin D deficiency in individuals over 50 leads to increased risk of fractures, however, this recent research shows that younger individuals are also very susceptible to fractures due to vitamin D deficiency. This is likely because vitamin D is necessary for the proper use of calcium and phosphorus in the bone. While rickets is generally very rare in the United States and developed world, many people may not receive enough vitamin D for optimal health.
Vitamin D dosage and sources of vitamin D
The RDA or as it’s now known as, the reference dietary intake, for vitamin D was set at 600 IU for individuals between 1 and 70 years of age in November 2010. However, many medical professionals believe that these levels are too low. The best way to determine the amount of vitamin D one needs for optimal health is to have one’s blood levels checked as it’s highly individual, and depends on how much one manufactures from the sun or gets from food sources.
The sun is obviously the largest source of vitamin D. However, how much vitamin D you are able to produce from the sun depends on your skin tone, degree of latitude, amount of skin exposure and time of day. The most vitamin D is produced when the majority of the skin is exposed during mid-day. It should also be noted that sunscreens that block ultra-violet rays, also block the production of vitamin D. Food sources of vitamin D include egg yolk, fish, fish oil, cod liver oil, cheese and beef liver.
While further research needs to be done, this study illuminates the importance of proper vitamin D intake for young, female athletes.

[NaturalNews] In a groundbreaking new study just published in the peer reviewed journal Stem Cells, researchers at UCLA’s Jonsson Comprehensive Cancer Center Department of Oncology found that, despite killing half of all tumor cells per treatment, radiation treatments on breast cancer transforms other cancer cells into cancer stem cells which are vastly more treatment-resistant than normal cancer cells. The new study is yet another blow to the failed and favored mainstream treatment paradigm of trying to cut out, poison out or burn out cancer symptoms (tumors) instead of actually curing cancer.
Senior study author Dr. Frank Pajonk, associate professor of radiation oncology at the Jonsson Center, reported that induced breast cancer stem cells (iBCSC) “were generated by radiation-induced activation of the same cellular pathways used to reprogram normal cells into induced pluripotent stem cells (iPS) in regenerative medicine.” Pjonk, who is also a scientist with the Eli and Edythe Broad Center of Regenerative Medicine at UCLA, added “It was remarkable that these breast cancers used the same reprogramming pathways to fight back against the radiation treatment.”
In the new study, Pajonk and his team irradiated normal non-stem cell cancer cells and placed them into mice. Through a unique imaging system, the researchers observed the cells differentiate into iBCSC in response to radiation treatments. Pjonk reported that the newly generated cells were remarkably similar to non-irradiated breast cancer stem cells. The team of researchers also found that the radiation-induced stem cells had a more than 30-fold increased ability to form tumors compared with non-irradiated breast cancer cells.
Despite mounting evidence, mainstream medicine clings to surgery, chemo and radiation and ignores natural solutions
Despite all the billions of dollars spent on cancer, the 40 year “war on cancer” has been a losing one by any honest evaluation. One hundred years ago, anywhere from 1 in 50 to perhaps 1 in 100 people could be expected to develop cancer. Now it is estimated that 1 in every 2 men and 1 in every 3 women will be diagnosed with cancer in their lifetimes. Despite more people around the world developing cancer and dying from cancer every year, mainstream medicine continues to cling to failed treatments which more often than not fail to eliminate the cancer and help cancer spread and return more aggressively than ever. Notably, two of the three major mainstream cancer treatments – radiation and chemo – are themselves highly carcinogenic.
One might think that the new study provided ample reasons to rethink using radiation. However, the study authors looked at the results as an opportunity to continue and enhance the use of radiation by finding ways to control the cell differentiation. What the scientists failed to note is that natural alternatives have already been found which prevent the development of cancer stem cells.
As just one example, Natural News reported in May 2010 that a University of Michigan study had found a compound in broccoli and broccoli sprouts which had the ability to target cancer stem cells. See:
The researchers failed to note how cancer cells fought against unnatural treatments. They also failed to take into account the mounting evidence that the best way to beat cancer as well as avoid it is to build and enhance our natural first line of defense – our immune system.
The safest and most effective way to enhance the natural immune system and fight cancer in general is by working with nature. It is also by far the least expensive way, and therein likely lies the rub. You can’t patent and profit from nature like you can with mainstream drugs and treatments.
Note: Neither NaturalNews nor this author condone the inhumane use of animals in medical studies.
