Lycopene May Reduce Exercise-Induced Asthma

TEL-AVIV, Israel--In the December Allergy (55, 12:1184-9), researchers from Tel-Aviv University, based here, found that a daily dose of lycopene may offer a protective, antioxidant effect against exercise-induced asthma (EIA).

Researchers, led by I. Neuman, assessed the effect of LYC-O-MATO-brand lycopene on airway hyperreactivity in patients with EIA. In a one-week, randomized, double-blind, placebo-controlled study, patients received 30 mg/d of lycopene. The investigators then conducted measurements using baseline pulmonary function and a seven-minute exercise session on a motorized treadmill followed by an eight-minute rest. A four-week washout interval was allowed between each protocol.

The researchers noted that all patients given placebo showed significant postexercise reduction of more than 15-percent in their forced expiratory volume. On the other hand, after receiving 30 mg of lycopene per day, 55-percent were significantly protected against EIA. Serum analyses of the lycopene-supplemented patients found elevated blood levels of lycopene compared to the placebo group, with no change in retinol, tocopherol or carotenoid levels.
