Nutrition Research Oct 02 PDFs available

September 14, 2002

Hi All,

Nutrition Research 22, Oct. 2002 is in and PDFs available. Here are some

titles and one abstract on lycopene levels recommended. I take about 70

grams/day tomato paste, which is probably as high or higher that ketchup in

lycopene. I guess it is just about right.

Effect of low dose lycopene intake on lycopene bioavailability and oxidative

stress

A. V. Rao and Honglei Shena

“Lycopene is a naturally present carotenoid in many fruits and vegetables.

Tomato and tomato products constitute the major source of dietary lycopene

in North America. It is an important antioxidant providing protection

against damage from free radicals. A fully randomized, cross-over study was

conducted to investigate the dose-response relationship of lycopene on the

absorption and in vivo antioxidant properties at low level of intake (5, 10,

20 mg). In this study lycopene was provided in the form of ketchup or

oleoresin capsules. Twelve healthy human subjects underwent two-week wash

out period, followed by two-week test period. A significant increase (p <

0.05) in serum lycopene level was observed for both ketchup and capsules at

all levels of intake. Lipid and protein oxidation were also reduced

significantly (p < 0.05). No significant differences were observed between

the two treatments. Based on these results an intake of 5 to 10 mg lycopene

per day is recommended.”

Heinz ketchup (8ml) contained 1 mg of lycopene.

Cheers, Al.
