Nibble with caution when you go online

Question: With all the information on the Internet about nutrition, how can I sort out scientifically sound material from misinformation?

Answer: Surfing the Web for nutrition and other health information can be enlightening and fun. But surf with caution. The ease of Internet publishing allows unrestricted information to appear on the Web, so there is a lot of misinformation and quackery in cyberspace.

To avoid being misled or "quacked," here are a few words of advice along with some good nutrition or health information Web sites:

Web quackery: Beware of information that:

+ Uses words such as "breakthrough," "miraculous," "overnight results," "revolutionary" and "secret."

+ Makes unsubstantiated claims: "Our soil can no longer supply enough good-quality food."

+ Alleges some kind of conspiratorial theory: "This information is unavailable through regular medical channels and is being sup-pressed by the medical community."

Be skeptical about testimonials and case histories, and don't put faith in people claiming to be the "expert." There are even doctors and other health providers who willingly or unknowingly distort facts and make strong emotional appeals to get us to support a pet theory or to buy something.

Be patient. Use multiple sources to gather information to ensure accuracy.

Finally, use common sense. Remember the adage: If it seems too good to be true, it probably is. Before trying anything new that may affect your health, talk to your doctor, a pharmacist or, in the case of nutrition, a registered dietitian.
