Radical longevity The powerful plan to sharpen your brain, strengthen your body, and reverse the symptoms of aging

Nutritionist Gittleman (Hot Times) offers strategies for answering the "distress calls" that bodies issue before progressing into illness and disease in this innovative guide. Rather than taking an "antiaging" approach, Gittleman breaks down the science behind aging, and her advice comes in three parts: the first introduces her seven rules for longevity, which focus on immunity, minerals, and "the gut-brain connection." Part two tackles environmental toxins and offers a meal plan consisting of unprocessed foods, and the final section covers brain, heart, and joint health. Many of Gittleman's fixes are natural solutions--"flower remedies," she writes, are extracts that function similar to homeopathy and can help with "emotional turbulence," and she recommends broccoli seed oil for improving skin health. She doesn't skimp on detail--her discussion of at-home toxins is particularly extensive and, at times, overwhelming--and there's no shortage of resources and exercises to help readers put her advice into practice. Those with a mind for alternative medicine will appreciate the wealth of information on offer. Agent: Coleen O'Shea, Allen O'Shea Literary Agency. (May)
