Lycopene May Protect Against Asthma
Posted by: Dr. Mercola

Lycopene, a carotenoid found in red-hued fruits and vegetables including tomatoes and others (see table below), seems to reduce the risk of exercise-induced asthma (EIA) in some patients, Israeli researchers report.

Researchers studied 20 patients with EIA

  • Patients were randomly assigned to receive a once-daily treatment of 30 mg of a lycopene supplement or an inactive placebo
  • After one week of treatment, 55% of the patients given lycopene showed significant protection against EIA
  • Patients taking the lycopene supplements had elevated blood levels of lycopene compared to the placebo group, and no changes were found in levels of other carotenoids or other antioxidants such as retinol (vitamin A) or tocopherols (vitamin E)
The researchers note that there is some evidence that dietary antioxidants protect against EIA and lycopene has been shown to be a potent antioxidant.

The lycopene used is a proprietary formula known as LYC-O-MATO, produced by the Israeli company LycoRed.

Researchers conclude "Our results indicate that a daily dose of lycopene exerts a protective effect against EIA in some patients, most probably through an in vivo antioxidative effect."

Add exercise induced asthma to the long list of lycopene benefits (see articles below).

However, it is worth pointing out that the product used in this and many of the studies on lycopene is a product called LYC-O-MATO. This prduct is made by an Israeli company named "LycoRed". However, LycoRed is owned by one of the biggest pesticide manufacturers in the world named "Makhteshim-Agan Industries". The company produces many pesticides, herbicides, fungicides, and industrial chemicals.

People should be aware of this fact if purchasing products with this ingredient. It is a shame that the same companies making $$ off people trying to be healthier are also the companies poisoning us in the first place!!!

So the answer is to get your lycopene from foods (see table below), preferably organic if possible.
