Broccoligroddar verkar kunna lindra astma

Detta är iofs från 2009 men iaf.

Här är ännu en orsak att trycka i sig den gröna broccolin.

Forskare vid UCLA rapporterade att sulforafan kan skydda mot inflammationer i luftvägarna mm.

I en artikel publiserad i journal of clinical immunology, visar forskarna att sulforafan ökar antioxidanter i människans luftvägar och bidrar till att skydda den mot fria radikaler som vi dagligen andas in, så som pollen, diesel avgaser och tobaksrök.

Fria radikaler kan orsaka vävnadsskador som kan leda till inflammationer i luftvägarna och astma.

"he UCLA team worked with 65 volunteers who were given varying oral doses of either broccoli or alfalfa sprout preparations for three days. Broccoli sprouts are the richest natural source of sulforaphane; the alfalfa sprouts, which do not contain the compound, served as a placebo.

Rinses of nasal passages were collected at the beginning and end of the study to assess the gene expression of antioxidant enzymes in cells of the upper airways. Researchers found significant increases of antioxidant enzymes at broccoli sprout doses of 100 grams and higher, compared with the placebo group.

The maximum broccoli sprout dosage of 200 grams generated a 101-percent increase of an antioxidant enzyme called GSTP1 and a 199-percent increase of another key enzyme called NQO1.

"A major advantage of sulforaphane is that it appears to increase a broad array of antioxidant enzymes, which may help the compound's effectiveness in blocking the harmful effects of air pollution," Riedl said.

According to the authors, no serious side effects occurred in study participants receiving broccoli sprouts, demonstrating that this may be an effective, safe antioxidant strategy to help reduce the inflammatory impact of free radicals."
