The emotional stress centers of

the brain

• Positive Stress is

– Is brief, infrequent, mild or moderate

– Is normal in everyday life

– Motivates, builds exploration and curiosity, and teaches the child to adjust

The child’s social and emotional supports help manage stress

and allow a return to normal

Stress Shapes the Brain

• Poor nutrition • Illness • Injury or trauma • Neglect • Violence • Family problems • Environmental toxins • Inadequate health care

Prolonged Stress can Harm a Child

http://feedingamerica.org/SiteFiles/child-economy-study.pdf

• Toxic Stress

– Long lasting, frequent, or intense

– Adverse childhood events (ACEs)

– Perceived by the child as overwhelming – Results in

• Anxiety • Anger • Emotional outbursts • Fear

Harmful if the child does not have enough social and emotional buffers

Toxic Stress

Toxic Stress Damages Brain

How Children Succeed by Paul Tough

• Why do some children succeed and some fail?

• Adverse Childhood Experiences (ACEs) reflect toxic stress -- correlates with poor academic, behavioral, lifestyle and physical/mental health outcomes

• Social emotional skills can mitigate toxic stress

Kids & Energy-Dense, Nutrient-Poor Foods

• Snacking = 30- 40% of daily energy• Daily calories increased • Carbohydrates increased • Fats increased

• Displace: Protein, fiber, vitamins, folate,calcium, magnesium, iron, zinc

Many American children fall short on nutrient intakes

Percent with nutrient intakes from food and dietary supplements below the EAR

Ogden, JAMA 2010 Fulgoni et. al., J of Nutrition, 2011

Only 2% of children have potassium intakes above the AI

The School Nutrition Success Story

• 55 million students • 32 million lunches/d • 35-40% kcals school vs

56% kcals at home • Improve nutrition • Lessen obesity • Improve behavior • Boost academic

achievement

Nutrients of Public Health Concern • Four nutrients of public health concern – calcium, vitamin D,

potassium and dietary fiber due to inadequate intake of key food groups

*NHANES 2003-2006; 2+ yrs Milk is the number 1 food source

2010 Dietary Guidelines for Americans -

Recommendations Age Servings of Dairy per Day

2-3 years old 2 Servings

4-8 years old 2.5 Servings *

9 and older 3 servings

What’s the Scoop On Flavored Milk?

• Dietary Guidelines uses fat- free chocolate milk as example of nutrient dense beverage

• Only 15 % of milk consumed is flavored contributing only 3 % of the added sugar and 2 % of the calories in children’s diets on average

• Children who drink flavored milk have better nutrient and total milk intake and similar added sugar intake and body weight as non drinkers

School Lunch: Findings • 10 years: rapid improvements (SNDA I,II,III)

– Protein, vitamins A & B-12, riboflavin, calcium, phosphorus, potassium and zinc

– Choices for entrees, fruit, vegetables the norm – More than half of the milk was no- or low-fat

• New Standards meet Dietary Guidelines 2010: – Less saturated fat, sodium – More fresh fruit & vegetables, whole grains – Better balanced, fewer calories

Benefits of Breakfast at School

Fewer disciplinary referrals

The Learning Connection: The brain develops through childhood & adolescence Experiences alter brain structure and function Health, physical activity, fitness, nutrition, emotional

support, peer interactions, and play* improve Cognitive Processing

Experiences alter brain structure

Health, physical activity, fitness, nutrition, emotional

Inhibition the ability to ignore

distraction & stay focused

Cognitive Flexibility the ability to switch

perspectives, focus of attention, or response

mappings

Working Memory the ability to hold

information in mind and manipulate it

Building Cognitive Control

Cognition is a Struggle

Cool Intelligence Hot Intelligence

Executive Function = Prefrontal Cortex

When Functional… • Make plans • Keep track of multiple

things • Discuss using past

knowledge • Evaluate ideas, reflect on

work • Make corrections • Engage in group dynamics • Control impulsivity

When Dysfunctional, struggles… • Planning projects • Time management • Verbal, written stories in a

sequential manner • Memorizing and retrieving

key information • Initiating tasks or generating

ideas independently • Retaining information while

using it (working memory)

Increased physical activity leads to more focused classroom

behaviors and

improved mathematics, reading, and writing test scores

49

Neuro-imaging and Neuro-cognitive testing

prove that

A growing number of schools are cutting daily physical activity opportunities

to provide additional classroom time on formal academic topics.

Does Activity Time Hinder

Academic Achievement?

No. CDC reviewed 50 school studies: No decrease in academic achievement when time

is allotted for physical education/recess/sports, and in fact… Positive relationships between classroom physical

activity time and indicators of academic achievement, classroom behavior, and cognitive function

www.cdc.gov/HealthyYouth, April, 2010

Optimal cognitive processing in a child

necessitates a period of decompression

after a period of concentrated instruction

Regularly scheduled periods within the [elementary school] day for unstructured physical activity and play.

(CDC, 1997)

Recess is …

The fewest minutes of recess occur in those schools

with 75% or more of its kids

on free & reduced meals – those with the highest need

Recess Augments PE Recess is not a substitute for PE PE is education, teaching the acquisition of motor skills for life-long physical activities and free play

PLAY* DEVELOPS SOCIAL & EMOTIONAL SKILLS

Play* = A Life Skills Class

Adapt, adjust to complex school environment

Practice and role-play social skills Learn communication skills:

negotiation, cooperation, sharing and problem-solving

SocialEmotional Learning

manage stress, organize learn and practice coping skills, curiosity, perseverance and self-control

Institute of Medicine Report May 2013

60 minutes per day Whole-of-School Approach:

• Before school • PE Daily • Recess Daily • 10-minute Breaks

between classes • After-school

We can’t raise a child’s IQ,

and we aren’t their teachers,

but if we are allowed

through improved nutrition and regular physical activity we can put a better student
