Is eating like our ancestors good for us?

Deborah Jeffrey is a registered nutritionist and dietitian. She says wheat, corn and other grains may worsen some conditions, but they do not affect everyone.

"I don't see any evidence that would say the majority of the population has problems. I think it's because grains and processed white-flour products are things that people tend to over-consume and take in excess calories through, so they just come up with these general statements that they should just be entirely avoided."

Yet that could mean people on the Paleo diet do not get enough carbohydrates, vitamins and fiber. This worries dietician Pat Compton.

"The keys have always been with what we should be eating, are balance, variety and moderation. And with this, the Paleo diet, you really are not getting that."

She adds that our Paleolithic ancestors failed to eat grains because they did not understand their effects on health.

Other nutritionists say the Paleo diet can be part of a healthy lifestyle. But they say many people fail to follow the diet for long periods because it is too restrictive.

But Robb Wolf says it is not difficult to replace grains in one's diet with other foods. He says people can eat yams or other root vegetables.

In recent years, the Paleo diet has become increasingly popular. But supporters of this way of eating say it can help anyone who wants a healthy lifestyle.
