The Basics: Vitamin D

Vitamin D is a most unique vitamin. Nicknamed the "sunshine vitamin, it is the only vitamin that can be manufactured from the reaction of ultraviolet rays with the cholesterol in skin. In addition, vitamin D action in the body more closely resembles the workings of a hormone, not a typical vitamin.

Vitamin D is best known for its role in bone health. Vitamin D aids calcium absorption, prevents calcium from being excreted from the kidneys and moves calcium from the bones to the blood when needed. A deficiency of vitamin D results in the disease rickets in children and osteomalacia in adults. In both cases, bones soften, bend, and break easily. Children with rickets show a characteristic "bowing" of their legs.

Newer research finds that vitamin D may also help protect against chronic diseases such as some types of cancer, type 1 diabetes, arthritis, multiple sclerosis and autoimmune diseases.

Food sources of vitamin D include fish oils, egg yolk, liver, milk, and fortified foods such as some brands of breakfast cereal, orange juice and soy milk. Many nutrition experts and researchers have determined that current recommendations for vitamin D intake are much too low. It is very likely that the RDA will be markedly increased in the near future.

Recommendations for breastfed infants
Since exclusively breastfed infants are at a higher risk of developing rickets, the American Academy of Pediatrics (AAP) recommends that infants receive vitamin D supplementation to ensure an intake of 200 IU per day. Supplementation should begin within the first 2 months of life, the most likely source being infant multivitamin drops. (Ask your pediatrician or health care provider regarding specific recommendations. Do not use a supplement designed for older children or adults).

Most infant formulas have sufficient Vitamin D and infants who consume 500 ml per day will reach the recommended daily allowance. Infants who consume less than 500 ml of formula should also receive supplemental vitamin D.

Older Kids
According to the AAP, the children's typical source of Vitamin D is the ultraviolet light in sunshine, but due to the risk of skin cancer, they don't recommend children spend unlimited time in the sun. (by the way, sunscreen blocks the UV rays needed to manufacture vitamin D).

Children with darker skin or who have limited exposure to sunlight usually require vitamin supplements or regular consumption of fortified foods.

Nutrition and Our Culture:
Part of the Problem OR Part of the Solution?

P.O.P. (Part of the Problem):

Misleading headlines
The headline on the money page recently read: The leaner you are, the richer you'll get.
I immediately reacted with skepticism and wondered how that assertion could possibly be true. Sure enough, the article did not support the claims of the headline. The article was based on the report The contribution of health to the economy in the European Union and accompanying commentary that found, among other things:

"Some studies have examined measures such as height, which reflects health in childhood, and body mass index, which provides an indirect measure of health. All other things considered, taller people earn more than average whereas obese people tend to earn less, although the adverse consequences of obesity are greater for women than for men. However, these findings could reflect biases linked to the social acceptability of body images rather than a direct link to productivity."

So while the report makes a case that greater overall health contributes to greater productivity (and, presumably, a higher income), it most certainly doesn't make a linear correlation between degree of leanness and the amount of wealth acquired (as the headline would imply). This type of headline promotes the "thin at all costs" ideal that is prevalent in today's media. While I agree that we need to strive for a healthful weight, this type of journalism promotes guilt and contributes to disordered eating, in my opinion.

What's most interesting is that the report (140 pages long!) looks at all kinds of issues, including the contribution of mental illness, alcohol, smoking, etc. to productivity and the economy. It's curious why the author chose to focus so heavily (no pun intended) on obesity.

P.O.S. (Part of the Solution):

1. Massachusetts involves the true experts -- students -- in decision making regarding healthy school environments

The report, Giving Kids the Voice of Authority: Engaging Students in the Fight Against Childhood Obesity, features the successes of student councils in six high schools across Massachusetts.

Each of the six high schools won a competitive $1,000 grant to participate in the “Students Taking Charge” initiative, launched by the Massachusetts Action for Healthy Kids Team. Through the initiative, student councils evaluated student satisfaction with the nutrition and physical activity options available to them, as well as their satisfaction with access to health information at their schools.

Using the survey results, student leaders developed advocacy plans and recommendations for specific pilot projects designed to improve wellness, which they presented to their schools along with more than 200 state legislators and community leaders.

The Massachusetts student councils also helped shape the “Students Taking Charge Toolkit”, a unique resource that helps high school students assess their school’s nutrition and physical activity policies, and recommend and implement changes.

2. Reaching the "tipping point" on eliminating trans fats

The news about the harmful effects of trans fat is certainly not news at all. In fact, most experts cite studies of the harmful effects of trans fats dating back to the early 90's. When I was a nutrition student in the early 80's, one of my professors warned us to avoid stick margarine. Seems the rats in her lab who were fed margarine died much sooner than the rats receiving vegetable oil!

The good news is that finally, food manufacturers and restaurants are beginning to take notice of the public outcry regarding artificial trans fat in foods. Arguably the most effective action to date has been the mandatory change to the Nutrition Facts food labels (which took effect January 2006). Rather than display high levels of trans fats on labels, the food industry seems to be responding by reformulating many items. Hopefully, this trend will continue. In the meantime, look carefully at food labels. You still need to look at the ingredient label to detect “partially hydrogenated” oils, the source of artificial trans fatty acids. Under current regulations, a food label can list 0 grams of trans fat if the amount per serving is less than .5 grams so several servings of a food could add up to a few grams of trans fat (and with trans fat, there is no minimum "safe" level defined).

News in Brief

Treasure hunt with the Munch Crunch Bunch
Jan Wolterman and registered dietitian Melinda Hemmelgarn have teamed up to produce a brand-new story/activity book that provides a smorgasbord of fun as it teaches children about healthy food choices. This innovative publication, containing forty-five fruit and vegetable riddles (foodles), invites children to play detective on food shopping trips. Learn more about the book and accompanying website at http://www.munchcrunchbunch.com

Report on Online Food Advertising Targeting Children
A report released by Kaiser Family Foundation found that more than eight out of ten (85%) of the top food brands that target children through TV advertising also use branded websites to market to children online. Unlike traditional TV advertising, these corporate-sponsored websites offer extensive opportunities for visitors to spend an unlimited amount of time interacting with specific food brands in more personal and detailed ways. The report, titled It’s Child’s Play: Advergaming and the Online Marketing of Food to Children, is also accompanied by a webcast.

More on Children's Advertising
The American Academy of Pediatrics has released the policy statement Children, Adolescents, and Advertising. The AAP warns that increasing media exposure may contribute significantly to childhood and adolescent obesity, poor nutrition, and cigarette and alcohol use.
