Investigative journalist and islander Jo Robinson will talk this weekend about her discoveries regarding restoring nutrients bred out of our food over thousands of years.

For farmers and gardeners, she will recommend vegetable varieties for optimum nutrition and flavor in time for planting, and for people shopping at the farmers market or grocery store, she will share ideas on selecting and preparing vegetables to preserve nutrients.

Robinson is the author, most recently, of “Eating on the Wild Side: The Missing Link to Optimum Health,” which was published by Little, Brown and Company. It was released last summer, received considerable attention and was featured in several magazines and on television and radio, including  CNN and NPR’s Science Friday and Fresh Air.

In addition to her research, Robinson  gardens on Vashon.

The Vashon Bookshop will have copies of Robinson’s book, and she will bring handouts listing her recommended vegetable varieties.

Robinson’s presentation will be at 1 p.m. Saturday at the Land Trust Building. A $5 donation is requested.
