In the United States, Canada, Europe, Australia, New Zealand and Asia, 30-50% of children and adults are reported to be deficientVitamin D. A 2011 medical study, “Prevalence of vitamin D deficiency,” found that more than 42 percent of Americans don’t get enough vitamin D.
“Vitamin D deficiency is a very serious problem for me and my patients,” said Dr. Janette Nesheiwat, a medical writer for Fox News. “Vitamin D levels can affect many aspects of the body, including digestion. system, sleep, mood, energy and levels of vitamins and minerals in the body.”
Vitamin D aids in calcium absorption and promotes bone growth and mineralization. Recent studies have linked vitamin D deficiency with more than a dozen cancers, heart disease, periodontal disease, autoimmune disease, chronic skin disease, obesity, depression and Alzheimer’s disease. A severe deficiency can lead to rickets (soft bones, crooked legs, growth retardation, and bone pain) in children and osteoporosis (weakened bones) in adults. Conversely, adequate vitamin D protects the brain from toxic chemicals and reduces pain.
“Due to the lack ofSunlightWith proper nutrition, many Americans are deficient in vitamin D. “People who work indoors, such as doctors who work 14-15 hours, or those who eat an unhealthy diet, are more likely to be deficient,” Neshevat said.
Harvard Medical School has pointed out in an article that, in theory, under the right circumstances, humans need to be in the sun for 10 to 15 minutes every few days, including arms and legs, without using sunscreen. , can produce enough vitamin D.
And according to the Centers for Disease Control and Prevention (CDC), 15 minutes of bright sunlight can damage unprotected skin. Skin cancer is the most common cancer in the United States, and approximately 9,500 Americans are diagnosed with skin cancer every day, according to the American Academy of Dermatology (AAD).

mushroomis the only vegetarian diet with vitamin Dsource. Wild mushrooms generally contain more vitamin D than commercially grown mushrooms due to exposure to sunlight. Of course, UV-treated mushrooms will be higher in vitamin D.
In addition, egg yolks are another source of vitamin D, and some studies suggest that eggs from pasture-raised or free-range chickens provide more vitamin D.
Likewise, consuming too much vitamin D (known as vitamin D toxicity) can be harmful. Signs of poisoning include nausea, vomiting, poor appetite, constipation, weakness and weight loss. Too much vitamin D can also damage the kidneys. It can also raise calcium levels in the blood. High levels of calcium in the blood (hypercalcemia) can lead to confusion, disorientation, and heart rhythm problems.
