Are the health benefits of vitamin D a myth or a reality? Low levels of vitamin D are prevalent in all age groups and have been associated with many health problems such as cancer, rickets, and osteoporosis. But, is vitamin D really a miracle drug? Here are some facts to keep in mind when considering vitamin D supplements. Read on to learn more! Vitamin D is essential to healthy bones and is a powerful antioxidant, but the benefits are far-reaching.
Low levels of vitamin D are common in all age groups
It is important to eat foods high in vitamin D, such as fatty fish and certain dairy products. Although most foods naturally contain vitamin D, they often do not contain enough to cause health problems. In addition, many traditional sources of vitamin D are now fortified. That means that you may need to increase your vitamin D intake. Here are some ways to get enough vitamin D in your diet:
Studies suggest that lower 25(OH)D levels are associated with prolonged hospitalization and mortality in the postsurgical setting. Moreover, vitamin D has widespread immunobiological effects, which have been recognized as a potential modulating factor during and after transplantation. The high immunomodulation and lack of physical activity in transplantation recipients makes them a particularly susceptible population for long-term bone dysfunction and infection. Additionally, recipients of solid organ transplants are often vitamin D-deficient, which may result from the limited sun exposure and physical activity.
The elderly are at particular risk for vitamin D deficiency. They spend less time outdoors and produce less cholecalciferol than younger adults. Elderly people are also more likely to become institutionalized than others. In addition, they often have poor skin elasticity, making it difficult to get adequate vitamin D from foods. A recent study showed that low levels of vitamin D are common in people of all ages.
While the outlook for people with vitamin D deficiency is generally good, it is important to remember that it can take several months before the body’s immune system has fully recovered. People with severe deficiency may suffer from rickets in children or osteomalacia in adults. The latter can lead to permanent bone deformities. If left untreated, severe vitamin D deficiency may result in heart failure, convulsions, and even premature death.
People with poor nutrition are at higher risk for vitamin D deficiency. In addition to inadequate nutrition, people with darker skin may also have lower levels of vitamin D. Because their skin contains high levels of melanin, they are less able to produce vitamin D from sunlight. Chronic illnesses can also contribute to vitamin D deficiency. If you are unable to get adequate amounts of sunlight, make sure to get enough vitamin D supplements.
Low levels of vitamin D are associated with rickets
Deficiency in vitamin D is one of the major causes of rickets, a deformity of the bones. Vitamin D is essential for the absorption of calcium and phosphorus, two elements that build strong bones. Lack of exposure to sunlight is one of the primary causes of vitamin D deficiency, but it can also be a result of other conditions, such as celiac disease or malabsorption syndromes. Some women with darker skin may not be able to absorb sufficient vitamin D from sunlight. Babies with limited or inadequate sun exposure are more likely to be born prematurely.
Vitamin D deficiency causes a blood calcium imbalance, leading to a decreased ability to build bones. Children with this condition have elevated levels of the calcium-regulating hormone, parathyroid hormone, causing secondary hyperparathyroidism. In addition, they have abnormally low levels of the mineral phosphate, which contributes to rickets. It is important to provide adequate amounts of vitamin D to children, since this can lead to other health complications.
Doctors can make a diagnosis of rickets by looking at x-rays to determine the extent of bone loss and abnormality. Bone biopsy may be necessary to confirm rickets or determine whether another condition is the cause. Vitamin D is essential in the prevention and treatment of osteoporosis, and exposure to sunlight can help prevent this disease. A doctor will determine a child’s vitamin D status based on the amount of sun exposure, phosphorus content, and serum calcium and phosphate levels.
While the outlook for children with a mild vitamin D deficiency is good, a severe vitamin D deficiency can result in osteomalacia, a disease of the bones. In children, it can lead to breathing problems, skeletal deformities, and even cardiac issues. In adults, vitamin D deficiency is associated with osteoporosis and rickets.

In the 21st century, low levels of vitamin D are a leading cause of nutritional disease among infants. Unlike iron deficiency, low levels of vitamin D are not easily detected and have no recommended screening methods. As a result, the presentation of rickets may vary greatly from one child to the next. In one recent study, a 6-month-old white boy developed inconsolable crying followed by two episodes of infantile seizures.
Low levels of vitamin D are associated with osteoporosis
Low levels of vitamin D are linked to an increased risk of osteoporosis. Vitamin D deficiency can lead to rickets, a form of childhood bone disease that can lead to permanent deformities. Low levels of vitamin D are also associated with coronary heart disease, diabetes, breast cancer, and bowel cancer. Vitamin D deficiency is also associated with a higher risk of Alzheimer’s disease and certain types of cancer.
To study the association between low levels of vitamin D and osteoporosis, researchers conducted a retrospective analysis of medical records. In this study, researchers identified patients with osteoporosis using World Health Organization criteria. This included a reduction of T-score on the bone mineral density (BMD) scale, fragility fractures, and low levels of 25-hydroxyvitamin D in the blood.
The association between vitamin D and osteoporosis is based on the biologically active form of vitamin D, called 1,25-dihydroxyvitamin D. Vitamin D promotes calcium absorption in the intestine, maintaining serum calcium levels and phosphate levels. Low levels of vitamin D induce excessive levels of parathyroid hormone, which in turn leads to increased bone absorption. Low levels of vitamin D may also be the cause of low calcium levels. Vitamin D and PTH work together to mobilize bone calcium and enhance calcium reabsorption in the kidney.

In addition to osteoporosis, low levels of vitamin D are also associated with secondary hyperparathyroidism, bone turnover markers, and fracture risk. Low vitamin D and low BMD are robust predictors of osteoporotic fracture. While several studies have demonstrated a positive association between low serum levels and low BMD, others have reported no significant association. A few studies have investigated the relationship between low serum levels of vitamin D and osteoporotic vertebral fractures, which commonly occur at the thoracolumbar junction.
Vitamin D deficiency increases the risk of fragility fractures by 31 percent. In a recent study, thirty subjects aged 57-60 years were examined and half of them were vitamin D deficient. Half of these individuals died of unnatural causes. Low levels of vitamin D are associated with an increased risk of hip and nonvertebral fractures. This relationship is not clear, but these findings suggest the importance of vitamin D supplementation in the prevention of osteoporosis.

Low levels of vitamin D are associated with cancer
Low levels of vitamin D have been linked to cancer. According to a nested case-control study published in the British Medical Journal (BMJ), individuals with deficient levels of the vitamin had a 31% greater risk of colorectal cancer. On the other hand, people with the highest circulating vitamin D levels had the lowest risk of colorectal cancer. While more research is needed, current research is promising.
Researchers have also linked low vitamin D levels with prostate and breast cancer. One meta-analysis of many studies showed an inverse relationship between vitamin D levels and the risk of developing these cancers. High vitamin D concentrations were linked to lower breast cancer risk in a preliminary study. Further research is needed to verify this link in humans. Although low levels of vitamin D are associated with cancer, the risk of cancer is significantly lower in men with high levels of vitamin D.
One study conducted at the Northeast Radiation Oncology Center in San Diego, CA, reported that higher serum levels of vitamin D are associated with lower risk of cancer. According to this study, adequate levels of vitamin D significantly reduce the risk of all types of invasive cancer combined. The authors cited studies examining the role of vitamin D metabolites in the development of cancer. These findings have implications for the treatment of cancer.
Although the relationship between low levels of vitamin D and cancer is weak, it has increased in recent years. A study of 44,778 twins has suggested that solar radiation plays a significant role in the development of breast cancer in different regions. Another study found a low correlation between breast cancer risk and vitamin D levels and low levels of vitamin D in northern latitudes. Moreover, the researchers found that women living in high and intermediate-solar-exposure areas had a significantly lower risk of developing breast cancer than those in lower and intermediate solar exposure zones.
The inverse correlation between vitamin D and cancer mortality was first noted over 80 years ago. Substantial studies in 1980 and 1992 linked low levels of vitamin D with a high risk of colon cancer and prostate cancer. The authors proposed that the higher the levels of vitamin D, the lower the risk of colon and prostate cancer. Moreover, they found an association between low levels of vitamin D and the progression of melanoma.
