The ill effects of fake news on both our health and the health of our society has been on my mind.

Role in the Human Body

Vitamin D is a fat-soluble nutrient essential for bone growth and general health. It is acquired through diet and exposure to sunlight.

Vitamin D is an essential component of bone health in both children and adults. Without vitamin D, bones do not calcify properly, leading to the condition known as “rickets” in children. Vitamin D also plays an important role in tooth development. It is necessary for proper tooth eruption, growth, and strength. Through its role in regulating calcium and phosphorus metabolism, vitamin D plays a continuing role in maintaining a stable nervous system, normal heart activity, and normal blood clotting.

A unique property of vitamin D is that it functions very much like a hormone. It target tissues include the kidneys, intestines, and bones, where it helps regulate calcium and phosphorus homeostasis. Its specific activity in the intestines involves stimulating the synthesis of active transport proteins that mediate absorption of calcium. In bone tissue, vitamin D plays a role in regulating calcium deposition (bone mineralization) and mobilization. A role for vitamin D in immune system modulation is now under investigation.

“Someday.” That’s the word that stuck out to me in the passage above when I came across it during my research. I was preparing to go undercover for The Dr. Oz Show to investigate what for-profit stem cell clinics are telling vulnerable patients.

Experts estimate Americans lose a billion dollars or more each year due to scanner mistakes at all kinds of different stores.

Electronic cigarette

E-cigarettes have been billed as a safer alternative to regular cigarettes, but these devices have the potential to be extremely dangerous as well. While some say that the chemicals in the liquids can cause harm and that these devices may increase smoking habits in children, I am also deeply concerned about their potential to explode, making them more like flamethrowers or mini-bombs than anything else.
