The vitamin that kills cancer cells. Canadian researchers from McGill University have discovered new evidence about the effect of vitamin D on cancer cells.
A high level of vitamin D significantly extends life compared to deficiency. John White and David Goltzman’s team identified the power of vitamin D to kill cancer cells. It activates mechanisms that inhibit the functions of c-MYC proteins, which are responsible for cell division. In over half of cancer cases, c-MYC protein levels are elevated.
The vitamin that kills cancer cells
Previous studies have linked low levels of vitamin D to various types of cancer and cardiovascular diseases. Below 20 ng/ml, vitamin D levels are associated with a 50% increase in mortality among elderly adults. A lack of vitamin D, caused by diet, lack of sun exposure, and spending time indoors, is linked to digestive cancers, including colon cancer, and certain forms of leukemia.
Vitamin D supplements slow the production of abnormal and malignant cells. Additionally, vitamin D protects genetic integrity. An adequate amount of vitamin D in the body helps eliminate toxic substances, including cancer cells.
Consuming foods rich in vitamin D and sun exposure (with appropriate sun protection) is recommended daily. An annual analysis during the winter season can detect vitamin D deficiency. Vitamin D supplements should only be taken upon a doctor’s recommendation.
The best food sources of vitamin D include:
Fatty fish: Fish such as salmon, mackerel, herring, sardines, and tuna are rich sources of vitamin D.
Fish oils: Fish oils, whether as supplements or part of the diet, are an excellent source of vitamin D.
Eggs: Egg yolks are a modest source of vitamin D.
Mushrooms: Certain types of mushrooms can produce vitamin D when exposed to sunlight.
Fortified dairy products: Some dairy products, such as milk, juices, and fortified cereals, may contain added vitamin D.
Meat: Certain types of meat, such as beef liver, contain small amounts of vitamin D.
Fish oil is the most important food source of vitamin D
Moreover, moderate sun exposure is a natural way to produce vitamin D in the body, as the skin produces this vitamin in the presence of UVB rays.
Symptoms of Vitamin D Deficiency
A lack of vitamin D can cause various symptoms, including:
Constant fatigue or weakness: Difficulty concentrating and decreased energy levels.
Bone and muscle pain: Pain and increased sensitivity in bones and joints.
Depression or anxiety: A lack of vitamin D may be associated with mood disorders.
Weakened immune system: Increased susceptibility to infections and frequent colds.
Sleep problems: Difficulty in establishing and maintaining regular sleep.
Increased risk of bone conditions: A lack of vitamin D may increase the risk of osteoporosis or bone fractures.
It is important to discuss with a doctor or a nutrition specialist if you notice these symptoms to evaluate your vitamin D levels and receive appropriate advice and treatment.
When to get tested for vitamin D levels
Optimal vitamin D levels can vary based on criteria set by various medical organizations. Generally, the recommended optimal level of vitamin D in the blood is between 20 and 50 nanograms per milliliter (ng/mL). However, for certain conditions or specific age groups, these values may vary.
Tests to determine vitamin D levels in the blood can be performed at the doctor’s recommendation or in specific situations, such as:
If you have symptoms associated with vitamin D deficiency, such as fatigue, bone and muscle pain, or immune weakness.
If you belong to a high-risk group for vitamin D deficiency, such as individuals with darker skin (who need more sun exposure to produce vitamin D) or individuals with certain medical conditions that may affect the absorption of this vitamin.
At the doctor’s advice or for bone health assessment, especially in older individuals or those at high risk for osteoporosis.
In general, it is recommended to consult a doctor to determine if you need vitamin D tests and when you should undergo these tests based on your medical history and specific health needs.
