Investigative journalist Jo Robinson spent the past 15 years poring over science journals to find out which tomatoes have the most lycopene (the smallest), how to prepare garlic to get the most allicin (crush it and let it sit), and what lettuce has the most nutrients (red leaf). The results of her work are in 'Eating on the Wild Side,' a user's guide to choosing the most nutritious fruits and vegetables. "It's not about buying exotic, expensive things," says Robinson. It's knowing the best choice among common lettuces, apples, and carrots. [eatwild.com]
