Food allergies, health concerns and ethics can doom even the most sumptuously assembled mail-order baskets of cheese, chocolate, nuts and fruit to the regifting pile or the trash if the contents are a problem for the receiver.

The good news is that plenty of basket-makers know this, and it's now easy to find line-ups that cater to virtually any palate.

Whether your intended recipient has heart trouble, diabetes, food allergies or prefers organic foods, the Internet has made finding a tailored gift basket a breeze, says Debra Paulk, editor of Gift Basket Review Online magazine.

One fast-growing segment of the $4 billion gift basket industry is what Paulk calls "cause" baskets, which raise money for specific charities or cater to socially conscious consumers.

Here's a sampling of gift basket companies that offer specialized options:
