Objectives

• Identify importance of nutritional guidance in the medical system

• Identify reasons why nutritional insufficiencies are present in pediatric population

• Discuss importance and methods of nutritional intake and assessment among healthcare practitioners

• Describe nutrient testing for common disorders

Nutritional Medicine

• The importance of nutritional medicine and culinary medicine is reaching several medical schools.

• Poor nutrition is the leading cause of morbidity and mortality in the United States.

– Dietary risk competes with risk of tobacco and physical inactivity1

1. US Burden of Disease Collaborators. JAMA 2013.

Nutritional Medicine

• Nutrition‐related diseases account for more than 25% of visits to primary care providers1

1. Kolasa & Rickett. Nutr Clin Pract. 2010

How much training did doctors receive in medical school?

• 5‐7 hrs?

• What is requirement?

• ~ 37‐44 hrs1  in 1989, but 25‐30 hrs currently

• Medical schools provide 20 hrs, but only outside of required nutrition courses (electives, clerkships)2

• 75% of physicians feel their medical school training didn’t prepare them to speak with patients about diet & nutrition3

Modeling Healthy Behavior

• As a clinician, practicing a healthful behavior oneself is a powerful predictor of counseling patients with these same behaviors

Eisenberg et al. JAMA Mar 2013Frank E. JAMA. 2004

Our sensitivity to develop insulin resistance traces back to our rapid brain growth in the past 2.5 million years. An inflammatory reaction jeopardizes the high glucose needs of our brain, causing various adaptations, including insulin resistance, functional reallocation of energy‐rich nutrients and changing serum lipoprotein composition…

With the advent of the agricultural and industrial revolutions, we have introduced numerous false inflammatory triggers in our lifestyle, driving us to a state of chronic systemic low grade inflammation that eventually leads to typically Western diseases via an evolutionary conserved interaction between our immune system and metabolism

RDA, DRI, UL

• 1941 – Food and Nutrition Board of the National Research Council for military personnel 

• RDA – recommended dietary allowance

• DRI – Dietary Reference Intake

– replace RDA. Includes RDA, EAR (estimated average requirement), AI (adequate intake), UL (upper tolerable limit)

U‐shaped Curve

Dietary Reference Intakes: The Essential guide to Nutrient Requirements.  IOM. 2006 

DRI

• DRI is the amount of selected nutrients considered adequate to meet the nutrient needs of HEALTHY PEOPLE (estimated in children due to minimal data)

• DRI is for PREVENTION of disease

• DRI is not for treatment of chronic disease

• Optimal intakes for chronic disease still need assessment in future research

B‐vitamin RDA for infants

• RDA for Vitamin B6 is based on average B6 content in breast milk of only 19 women

• 6 of those women did not consume the RDA for B6

– Their breast milk contained only 1/10 of B6 of other women

West KD. Influence of vitamin B6 intake on the content of the vitamin in human milk. Am J Clin Nutr. 1976 Sep; 29(9): 961‐9.

What is “Adequate Nutritional Intake?”

• Medicine is still centered on single nutrient models:

Disease and Deficiency:

– Rickets – Vitamin D

– Scurvy – Vitamin C

– Beriberi – thiamine

– Pellagra ‐ niacin

Nutrients work Together

• Should single micronutrients be evaluated?

– Nutrients have Intricate & Complex metabolism

– Interact with each other

• Compete/Enhance for absorption – Vitamin C & Iron

– Iron & Calcium

• Compete/Enhance for utilization/enzymatic reaction– Fenton Reaction: Iron, Copper, Manganese

– Mitochondrial Metabolism: B‐vitamins/Magnesium/CoQ10/alpha lipoic acid

Individual dietary guidance

Are there special considerations?

NOoptimal health &

nutrition

Maintain healthy diet and RDA/AI

Yes(e.g. vegetarians/vegans, athletes, 

socioeconomic status, poor diet, illness (overutilization of 

nutrients/underabsorption of nutrients)

Plan for appropriate intake of specific nutrients based on special considerations

Table adapted from Dietary Reference Intakes: The essential guide to nutrient requirements. National Academy of Sciences. 2006

Micronutrient Supplements in Children

• Very little is known about micronutrient intakes in children

• More than 1/3 of infants, children and adolescents in United States use a dietary supplement

– Most commonly: multivitamin/mineral, Vitamins A, C, D, and calcium and iron

RL Bailey et al. The Journal of Pediatrics. 2012

Poor Micronutrients in Food

• Children have inadequate intakes for:

– Calcium/Vitamin D (low even when supplemented!)

– Magnesium

– Phosphorus

– Vitamin A

– Vitamin C

RL Bailey et al. The Journal of Pediatrics. 2012

Dietary Supplements improve Micronutrient Inadequacy

Table from: RL Bailey et al. The Journal of Pediatrics. 2012

Snacking has steadily increased in the population since the 1970s and snacks provide necessary nutrients. However, carbohydrates and added sugars tend to be overconsumed at snacking occasions. Replacement of current snack choices with nutrient‐dense foods could lower the risks of nutrient deficiencies and help lower excess nutrient consumption.

Bottomline

• Children are not getting enough nutrients

• Dietary Supplements do improve nutrient status

• However, we need to implement a “real food” diet as healthcare professionals.

– Remove processed, packaged, microwaveable foods

– Replace with: 

Identify Safe & Quality Supplements

• Manufacturers of Dietary Supplements should meet good manufacturing practices (CGMPs)– Insure quality– Insure purity

• ConsumerLab is a company that tests the quality and specifications of dietary supplements and vitamins.  In 2008, this company reported that over 25% of the supplements it tests has problems and 50% of vitamins don’t meet the required guidelines. 19

Nutritional Intake:Accurate? Informative?

• Do you eat your fruit and veggies?

• Do you drink milk?

• Do you eat meat?

How to inquire about nutritional intake in a busy clinician’s schedule?

• What  did you eat and drink yesterday?

• @Breakfast

• @Lunch

• @Dinner

• @Snacks
