Biofortification
Global Challenges
1. Population
2. Sustainability
3. Food and nutrition security
4. Climate change
Reducing Deficiencies
Diversify the diet
oExpensive and out of reach for many
Fortify food (with iron, iodine etc)
oNeed access to the market
oBuy processed food
Provide supplement (vitamin A, zinc, iron etc.)
oNeed access to health care system
oHigh cost
Answer?
oBIOFORTIFICATION!
BIOFORTIFICATION
Development of micronutrient rich staple foods using traditional breeding
practices and modern biotechnology to achieve:
oProvitamin A
oIron
oZinc
Concentrations that can have MEASURABLE effects of
nutritional status
Mostly a plant breeding strategy
oBut requires cross-discipline input to make it work, i.e.:
Plant breeding
Human nutrition
Plant nutrition
Economics
130 varieties released in 25 countries
oTesting in 55 countries
Definition:
oBioavailability the number of nutrients that are available for absorption
by the body, in the food
In the future:
oAll staple food crops will be naturally enriched with key nutrients
Goal micronutrient density as core trait in future breeding
Will lead to biofortification of all future variations

Document Summary
Global challenges: population, sustainability, food and nutrition security, climate change. Diversify the diet: expensive and out of reach for many. Fortify food (with iron, iodine etc: need access to the market, buy processed food. Provide supplement (vitamin a, zinc, iron etc. : need access to health care system, high cost. Development of micronutrient rich staple foods using traditional breeding practices and modern biotechnology to achieve: provitamin a, iron, zinc. Concentrations that can have measurable effects of. Mostly a plant breeding strategy nutritional status: but requires cross-discipline input to make it work, i. e. plant breeding. 130 varieties released in 25 countries: testing in 55 countries. Definition: bioavailability (cid:0) the number of nutrients that are available for absorption by the body, in the food. In the future: all staple food crops will be naturally enriched with key nutrients. Goal (cid:0) micronutrient density as core trait in future breeding. Will lead to biofortification of all future variations. Micronutrients are not subject to genetic erosion.
