  1. Lifespan Nutrition Preadolescence & Early Adolescence

  2. Puberty Important developmental and physical changes to the body Both girls and boys experience puberty between the ages of 10-17 Puberty brings heightened growth & growth spurts therefore nutrient intake and energy intake must also increase

  3. Effects of Nutrition on Puberty The age at which children experience puberty has lowered over the decades – specifically in girls Genetic factors play a role, such as increasing weight and nutritional intake of both males and females Girls with a higher BMI were more likely to have experience early puberty Researchers theorize that levels of body fat may trigger the release of hormones that begins the process

  4. Food Choices and Puberty It is also said that food choices may affect puberty Children with poor diets are more likely to go through puberty earlier Children with diets higher in vegetable protein tend to go through puberty approx. 7 months later than average While those with diets higher in animal protein go through puberty approx. 7 months earlier than average

  5. Soy Products Soy products are rich in isoflavones These compounds are similar in nature to estrogen – and have been linked to later puberty in girls while having lesser effects on boys Isoflavones are also found in whole grain products and both animal and vegetable protein – it therefore difficult to narrow down a single culprit

  6. The Role the Media Plays Voluntary guidelines from the Children’s Advertising initiative set limits for the advertising of foods, only within children’s programming. As children and youth age they have increased access to media and programming that do not fall under these guidelines.

  7. Estimates claim that children are exposed to many as 40,000 advertisements a year (Kaiser Foundation, 2004) The level of media usage among children has risen steadily in the last two decades and it has been proven that children with high levels of media usage consume foods that are less nutrient dense.

  8. Children and youth who are exposed to more food advertising tended to have a higher BMI than those who were not (Dovey, 2007) The use of media itself may be the issue, with increased media use there has been a reduction in the amount of time participating in physical activities.

  9. Debate format Developing an opening statement for your teams position Opportunity for rebuttal, counter argue each others opening statements Closing remark In your teams divide up these three roles… if anyone has aspirations of being a lawyer take the counter argument role on!

  10. Debate In two teams (I will split the class in two) Debate the following statement: “Advertising fast food or junk food should be banned in any programming that youth are likely to watch”
