But Aaron’s latest role is that of a young man whose weight has become such an issue, weighing in at 550 pounds, he was recently asked to leave a plane because he took up two seats.

“As I saw the seats, I’m literally hoping that no one had to sit next to me because I knew it wasn’t going to work if they did,” Aaron told NBC News.

The Centers for Disease Control and Prevention (CDC) report that Aaron’s struggles with his weight aren’t as unusual as you might expect. The CDC says that more than one third of kids and adolescents in the U.S. are overweight or obese. In addition to facing isolation and embarrassment, potentially continuing into adulthood, these children are at increased risk for numerous health ailments. Endowed Chair of Cardiovascular Health and Risk Prevention at Cook Children’s Don Wilson, M.D., warns, “most children with risk factors for cardiovascular disease will have them as an adult; being overweight or obese often results in weight related to health risks such as diabetes, high blood pressure, injury to bones and joints, disturbed sleep, fatty liver disease, abnormal blood fats and isolation and depression.”

To help children avoid problems caused by obesity in their adult life, parents have a responsibility to address concerns early. According to Wilson, “it is important to determine what, if any, cardiovascular risk factors your child may have, and begin working with your health care team in finding safe and effective long term solutions. Small changes at a young age can make a big difference in making sure your child has a healthy future.”

Becoming overweight or obese can happen to anyone; some factors can be controlled, while others are inevitable. One can’t control being predisposed to developing high blood pressure, having abnormal blood fats or family members with diabetes, for example, but there are always opportunities to improve one’s health, make lifestyle changes and develop a plan of action to reach a healthy weight.

Since children’s bodies are still growing, it can be difficult to identify when weight gain reaches a level of concern. Dr. Wilson suggests the following guidelines: “Is often difficult to simply look at a child and tell they are developing an unhealthy weight. That's why it's important that you calculate your child’s body mass index (BMI); there are several calculators available on-line. A BMI above the 85th percentile for age/sex is considered overweight, above the 95^th percentile is considered obese and over the 99^th percentile is regarded as morbidly obese.” The first step is to identify patterns that may indicate a problem; regardless of BMI, be sure your child is not gaining excessive amounts of weight each week or month and alert your doctor to any sudden changes. Bring up concerns during your child's health checkup and ask for guidance.

A common misconception is that poor diet and exercise is the only culprit for childhood obesity. These factors indeed have an impact in many cases, but an overweight child should never be blamed or labeled as “lazy,” as there are many other elements that can contribute to unhealthy weight gain. Be sure to rule out health-related causes while you are developing an appropriate weight-loss plan. Just as with adults, encouraging and motivating kids to lose weight can be a touchy issue. Parents often have the biggest influence to help their children become better informed about healthier food choices and the benefits of daily exercise. Wilson says, “As a concerned parent, you can help set realistic goals for weight, food and activities, talk about your child's food in terms of preference, preparation and portion size, increase physical activities for the entire family, discourage smoking and avoid smoking yourself and make healthy living a family affair.  Perhaps the most important thing you can do is to be a good role model for your child.

Aaron is using the uncomfortable experience of being kicked off his flight as motivation to speed up his weight loss plans. Remember, if you child’s BMI rises above the 85^th percentile or their weight gain is excessive (i.e. crossing percentiles on the CDC’s growth chart) be sure to discuss any underlying causes with your doctor and work with your family to develop healthy lifestyle patterns early on. Your child’s future depends on it.

For more information and to determine your child’s BMI, try using the American Academy of Pediatrics’ and Centers for Disease Control and Protection’s BMI calculators.

I was immediatley interested when I chanced on a recent radio interview with the author, Michael Moss, who has written a new book about the inner workings of the processed food industry. The book deals specifically with the reasons that these companies use three key additives – salt, sugar and fat – in the processed food they create and market.

The term processed foods sounds somewhat sinister, but some of the ways that food is processed such as pasteurization or freezing are quite beneficial to people for both health reasons and convenience. The primary goal in most processing of foods is creation of a food product that is near ready to eat and is stable on the shelf or in our homes for a long period of time. This particular goal and the goal of making tasty processed foods according to Mr. Moss is where the problem begins.

In the book, Moss interviews food scientists in many of the large processed food companies. These scientists are tasked with making tasty food products that apeal to a large group of people. Moss describes the use of the three key additives to mask odd or bitter flavors that develop during manufacturing and to hook consumers on taste.

Moss argues that company pressures to create new appealing snacks, grow market share and improve profitability often result in unhealthy foods that contribute to the U.S. and global obesity epidemic.

The interview concluded with the debate about what steps can be taken to reduce these activities and make healthier foods. The debate no doubt will continue between different philosophies of strict government regulation and independence of consumer choice.

I’ve downloaded the eBook and look forward to learning more and examining different viewpoints. In the meantime, my family and I will continue to see fresh ingredients and discover new recipes.
