THE STORY OF MICRONUTRIENTS BIOAVAILABILITY

• Mohamed El Guindi
• Professor of Pediatrics
• Nutrition, Hepatology, GIT
• National Liver Institute
• Menoufiya University
• Egypt

2
DO WE KNOW THE NUTRITIONAL CYCLE IN OUR REGION?
3
WHAT IS THE IMPORTANCE OF BIOAVAILABILITY STUDIES?

• How did we know that ascorbic acid enhances iron
  absorption?

• How did we know that phytates and tannates
  inhibits iron absorption?

4
HOW WE CAN BENEFIT FROM BIOAVAILABILITY STUDIES?

• Are their specific inhibitors and/or enhancers
  that we dont know in our diets?

• How can we really study the ones that are really
  not MN deficient?

5
THEREFORE WE MUST ADOPT OUR OWN BIOAVAILABILITY
STUDIESWHAT DO WE NEED?

• We need a central regional laboratory that can
  undergo the studies.

• We need stable isotope mass spectrometry

• We need the stable isotopes for each study

6
BIOAVAILABILITY STUDIES should be our main
research goal for the next decade
WE SHOULD AIM HIGH
