Nutritionist or Dietitian? Question: I'm looking for some expert advice on diet and weight loss. Should I hire a nutritionist or a dietitian? Answer: Eating healthfully may be challenging, but finding a qualified nutrition adviser can also be tough! Some states require individuals offering nutrition advice to be licensed; others let just about anyone hang out a shingle. And don't be fooled by nutritionists with Ph.D.'s, either. One survey found that as many as 71 percent of all "nutritionists" with Ph.D.'s held degrees from nonaccredited diploma mills. That's why it's best to search for a registered dietitian (R.D.). An R.D. has completed a prescribed course of study including a minimum of a bachelor's degree (many also have master's degrees) and supervised practice work, and has passed a qualifying examination. Also, to maintain their credentials, R.D.'s must complete continuing professional education requirements. To find an R.D. in your area, ask your doctor for a referral, or visit the American Dietetic Association's Web site at www.eatright.org
