Detox diets: Do they work?

Detox, or detoxification, diets are popular, but they're not scientifically proven.

Detox diets are touted as a way to remove toxins from the body. Specific detox diets vary — but typically a period of fasting is followed by a strict diet of raw vegetables, fruit and fruit juices, and water. In addition, some detox diets advocate using certain herbs and other supplements along with colon cleansing (enemas) to help empty the intestines. Most detox diets last seven to 10 days.

Some people report feeling more focused and energetic during and after detox diets. However, this may be due to a belief that they're doing something good for their bodies. There's little evidence that detox diets actually remove toxins from the body. Most ingested toxins are efficiently and effectively removed by the kidneys and liver and excreted in urine and stool.

It's also important to consider possible side effects. Among other problems, detox diets can lead to:

• Dehydration
• Fatigue
• Dizziness
• Nausea

If you're considering a detox diet, get the OK from your doctor first — and remember, the best diet is a healthy diet based on fruits and vegetables, whole grains and lean sources of protein.
