A STUDENTS COMMENT
“After taking this class and seeing all of the
new research that is being done, does
anyone think that the dietary guidelines
given to the American public will be
changing again pretty soon?”

Breeding for nutritional quality:
Challenges
1. Paradigm shift
2. Justification of improved nutrition
3. The levels that can be increased are low
4. Understand the potential impact on age
groups
5. Is it cost effective…?
- Shift in focus from production to integration
of multi-disciplines
- Plant breeders need to collaborate with
nutritionists
- Evidences are the only driving force - Explore advanced biotechnology
techniques
- Increase intake F&V

• Problem statement:
– Vitamin A (VA) deficiency causes over 600000
deaths per year
• Origin: South America
– Introduced in Africa in 16th century
– Introduced in USA in 20th century
– China produces 80% of the world total output
(primarily for starch-noodles)
• Salient features:
– Can grow in tropical, sub-tropical and
temperate regions

• Background – β carotene Vitamin A
• Design – Randomized, double-blinded, placebo-controlled

– 30 mg of β carotene and 25000 IU retinyl palmitate
– Daily: 18314 men and women
– Study period : 1983-1996

Carotene and Retinol Efficacy Trial
(CARET): 1996
• Results
– Study stopped 21 months early
– 28 % more lung cancer
– 17% more deaths
• Conclusions
– No chemopreventive benefit
– Excess lung cancer incidence and mortality
• Implications – Current smokers and asbestos-exposed workers,
should be discouraged from taking supplemental β-
carotene (and the combination of β-carotene with
vitamin A).
– Safety and efficacy should be demonstrated before
recommending use of vitamin supplements in any
population.
( J Natl Cancer Inst 1996;88:1550-9 )

Objective To determine if the effects of beta-carotene continued after
participants stopped taking the supplements
Results
– Men: No increase in mortality
– Women: 12% increase in Lung cancer (not statistically significant)
– 33% increase in lung cancer
– 37% increase in mortality (any cause)
– 44% increase in mortality by CVD
SMOKERS……?
CARET: Follow up- 2001
Study design:
29,133 male smokers in Finland
50 mg alpha-tocopherol
20 mg of beta-carotene
• 876 cases of lung cancer incidence
• Higher incidence –Beta carotene (18%)
• No interaction between AT and BC
• Mortality 8% higher in BC due to
lung cancer and ischemic stroke
