A 2011 Journal of Nutrition report indicates most consumers rely on foods fortified or enriched with synthetic vitamins for their essential micro nutrient intake. That is not surprising given that most of the vitamins we consume today are synthetic, according to Catherine Price, author, Vitamania. What may surprise many is that while in the early years of synthetic vitamin development the United States played an important role, today most of the market is under the corporate thumb of two European companies. And the majority of their production facilities are in China.
Last week in my note about Vitamania (see Journalist believes devotion to supplements keeps us from good health) I indicated Catherine Price, the author, had declined to answer questions. It had been two weeks since I had sent her questions and the deadline for replies was long past. Saturday, October 17, 2015, I received an answer.

Below are the questions and answers:

What was the main reason you wrote the book (other than the question your husband asked you in Lithuania)?
I wanted to gain a better understanding of a subject I took for granted. I also was curious about how the story of vitamins might change the way we should think about nutrition as a whole.
In one sentence how do you define a vitamin or a nutritional supplement?
(Sorry, I can't do it in one sentence!)
There's no chemical definition for a vitamin -- the word was coined in 1911 before they had been chemically isolated, and it turns out they're not all part of the same chemical family. The public tends to define vitamins (of which there are only 13) as a chemical that we need in very tiny amounts, and that we usually get from our diets, that is necessary to prevent a specific vitamin deficiency disease, but there exceptions to each of these statements.
A dietary supplement (that's the official term, not nutritional supplement) is defined by the Food and Drug Administration (which is the administration responsible for regulating America's supplements) as "a product intended for ingestion that contains a 'dietary ingredient' intended to add further nutritional value to (supplement) the diet."
There's more info on what substances that definition includes here: fda.gov/AboutFDA/Transparency/Basics/ucm195635.htm
Are you opposed to vitamins?
To clarify: we have a habit of using the word "vitamin" to refer both to the 13 essential vitamins (A, C, D, E, K and the 8 B vitamins) and to the much broader category of dietary supplements (there are some 85,000 dietary supplement products on the market in America). There's no way you could oppose the 13 vitamins -- we need them in order to survive! But I don't think that most people need to take them as pills. As for dietary supplements, I'm not necessarily for or against them, but I have a lot of concerns about their safety, efficacy, and the authenticity of their ingredients.
What was the greatest challenge to the book project?
A lot of the questions I thought were simple (what is a vitamin, how do vitamins work, what do they do, how much of each do we need) do not have answers.
What was the biggest surprise?
That was also probably the biggest surprise. But once I got over the terror of not having solid answers to my questions, I realized that we should use this uncertainty as a lesson: vitamins are a great example of how little we actually understand about human nutrition. Their story has taught me to stop obsessing about the minutiae of nutrition, and to just eat naturally nutrient-dense food.

An article published in Cancer, a a peer-reviewed journal of the American Cancer Society, points to a recent substantial increase in testicular germ cell tumor incidence among Hispanic adolescents and young adults in the United States. The trend was not evident among non-Hispanic whites.
Testicular cancer, among the most common types of cancer in adolescent and young adult men, is said to be one of the most readily treatable. The researchers concluded that heightened awareness is advisable concerning the increasing risk of testicular cancer among Hispanic adolescents and young adults. They recommend additional research to determine the cause of the trend.
Frank Chien, co-author, Increase in Testicular Germ Cell Tumor Incidence Among Hispanic Adolescents and Young Adults in the United States
The article, Increase in Testicular Germ Cell Tumor Incidence Among Hispanic Adolescents and Young Adults in the United States, was authored by Franklin L. Chien, BA, Rebecca H. Johnson, M.D., and Stephen M. Schwartz, Ph.D., MPH.
They found that between 1992 and 2010, the annual incidence of testicular cancer in 15 to 39 year-old Hispanic whites increased 58 percent from 7 cases per 100,000 in 1992 to 11 cases per 100,000 by 2010.
Incidence rates increased in cities for different subtypes of testicular cancer and for all stages of the disease. In the same 19 year interval, testicular germ cell tumor incidence among non Hispanic white young adults increased 7 percent, from 12 to 13 per 100,000. During the 2000 to 2010 period, incidence rates rose in Hispanic whites, but the researchers observed no significant trends in incidence rates among non Hispanic whites.
“Hispanic Americans comprise the fastest growing ethnic group in the United States. Until only recently, cancer incidence data for this population has been too sparse to accurately analyze testicular cancer trends among Hispanic men,” Johnson said in a press release. “The increasing rate of testicular cancer in adolescent and young adult Hispanic males, combined with the rapid expansion of the Hispanic population in the United States, is projected to have a measurable impact on the United States healthcare system.”

"Unfortunately, there’s nothing that Hispanic men can do to minimize their risk, since nothing is known for certain about modifiable risk factors," said Schwartz by email in response to a question about preventive measures Hispanic men might take.
Johnson noted that, in the past, non Hispanic white men have had the highest rate of testicular cancer of all racial and ethnic groups in the United States. Should the trend found in this study continue, the rate of testicular cancer among Hispanic Americans will outpace that of non Hispanic white men within the next few years.
