Exposure to sunlight can be very beneficial for our overall health. It can prevent cancer and increase the feeling of happiness and satisfaction.
Recent study has discovered that vitamin D, which our body creates from sun exposure, can protect us from breast, prostate and colorectal cancer. And we all know that cancer is the no.1 cause of death all around the world.
Dr. Cedric F. Garland from the University of California`s San Diego Moores Cancer Center is the one who discovered the link between cancer and vitamin D.
This discovery has been further proven by many other studies. Vitamin D has the power to prevent cancer because it stops the growth of cancer cells, it stimulates cellular differentiation, prevents production of blood vessels in the tumors and induces apoptosis- cell death.
The conclusion was reported in the Journal of cancer, stating that 4000 IU/d of vitamin D3 can inhibit the development of cancer.
Proper amounts of vitamin D can significantly reduce breasts cancer fatality, by 44%. Women with lower intake of vitamin D have 94% bigger chances of developing metastases and 73% higher death risk.
Dr. Sharif B. Mohr from the Naval Health research Center in San Diego says that: “Doctors must understand the importance of vitamin D levels (40-60 ng/mL) in cancer prevention. They need to tell their patients to increase the intake of this vitamin, especially in winter, to maintain normal levels of vitamin D.”
As he also said, vitamin D can be increase up to 80 ng/mL in case of breast cancer. Lack of vitamin D can increase the risk of breast cancer and lead to aggressive tumors and fatal outcomes.
Dr. Brian, the assistant professor of pediatrics states that more research are needed, but the ones they`ve conducted until now indicate that women with increased risk of breast cancer should also check and maintain proper levels of vitamin D.
A study from the Northwestern University Feinberg School of Medicine shows a link between vitamin D and prostate cancer. This vitamin can decrease the risk of prostate cancer development, because it obstructs the differentiation and growth of cancer cells.
This study was conducted in the period between 2009 and 2014 and included 1760 cancer screenings, which were compared to healthy controls.
The lead author or the research and assistant professor of Urology, Dr. Adam Murphy claims that the development of prostate cancer cells, if added in a dish with vitamin D, will slow down and they will become less aggressive, so the chances of their apoptosis increase.
Their latest research proves that healthy people have higher levels of vitamin D, compared to people with prostate cancer.
Vitamin D can also treat rheumatoid arthritis, make the bones stronger, and it can prevent other types of cancer. According to certain studies, vitamin D3 supplements prevent cancer growth.
Other types of cancer
Vitamin D, combined with calcium, can decrease the risk of all cancer types by 77%, in postmenopausal women.
As explained by Cedric Garland, from the Department or Family and Preventive Medicine at the University of California, San Diego: “Vitamin D produces a substance called E-cadherin, which structure the cells and holds them together. This prevents penetration of cancer cells in tissues and organs.
Reduced vitamin D levels let the cells of the breast epithelium divide, so their stem cells undergo rapid mitosis. The cells which multiply faster than the others create cancerous clones which then infiltrate through the basal lining. Long period of vitamin D deficiency will result in the cells going into the lymphatic, after what they will metastasize to the brain, bones and lungs, with probable fatal outcome.
Types of vitamin D
Vitamin D has 2 types: D2 (ergocalciferol) and D3 (cholecalcifelor). Vitamin D2 is produces by plants and D3 is produces in our body, by the kidneys and the liver, from exposure to sun.
Vitamin D3 is very important for calcium absorption in the gut, so it promotes healthy bones and teeth. Also, it is needed for proper immune and neuromuscular function, for soothing inflammation, treating diabetes, heart disease and chronic pain, as well as for cell growth.
Our body produces vitamin D3 from exposure to sun, but the optimal amount is not yet defined, it depends on age, sex, area of living and ethnicity.
According to the Institute of Medicine, recommended amounts of vitamin D are 600 IU for adults and 800 IU for people over 70.
Some cancer treatments increase the dosage up to 4000-10000 IU per day, but experts are warning that this can have severe effects on the health, especially the heart and the kidneys.
In order to determine the proper dose of vitamin D for treating some health issues, consult an experienced doctor, oncologist or a naturopath.
