When Martha Han of Duluth, Minn., shops for groceries, she considers the health of her children, ages 3 and 5.
Some products she buys are certified organic. For instance, she prefers organic grapes and apples for her kids because nonorganic ones contain the highest pesticide levels.
"I won't buy everything organic, but I like having the choice," she says.
Judging from sales nationwide and anecdotal information locally, people such as Han are pushing organics into the mainstream.
