Sick of gagging on heart-clogging slop when you take a road trip but clueless about where to find healthier fare in an unfamiliar town? "Healthy Highways: The Traveler's Guide to Healthy Eating" (Ceres Press, 2004, $18.95) could provide an up-to-date answer.


Going state by state, the book lists 1,900 restaurants, food co-ops and corner food stands that offer vittles described as vegetarian, organic or just plain better-for-you. A map locates these approved haunts and the book also gives driving directions -- something some other such books (none as new as this one) don't include.


Authors Nikki (a nutritionist) and David (a lawyer) Goldbeck -- who penned "The Supermarket Handbook," a guide to grocery shopping, in 1973 -- offer nutritional fun facts and quizzes. Example: "True or false? Saltwater fish have more than twice the sodium content of freshwater fish." ("False. The sodium content is the same.")


The book doesn't distinguish places that charge, say, $32 for an entree from those that charge $6. This could lead to some sojourners' showing up at places like the upscale Restaurant Nora in muddy shorts. Also, a book like this can become old quickly. Updates on the related might help.


Research is scant on the long-term effects of consuming conventional vs. organic foods. Still, reason the Goldbecks, foods like hormone- and antibiotic-free ham on sprouted wheat-grain bread have got to be better for you than some beef jerky and a Twinkie.
