And far to our chagrin, summer time’s most iconic fruits — stone fruits and berries — had been closely contaminated with fludioxonil, a neurotoxin sometimes used as a fungicide that has notably been linked to neurodegeneration and behavioral abnormalities1. To keep away from this and different pesticides, listed below are the objects the place we’d most extremely advocate selecting natural out of the greens and fruit in season now.
Peaches and Nectarines
Peaches and nectarines are presently of their peak season, which is able to final from June to September.
