Paleo diet-part1: What is it and why is it so popular?

Healthy Lifestyle

Nutrition and healthy eating

Is the Paleo diet, an eating plan modeled on prehistoric human diets, right for modern humans?

A paleo diet is a dietary plan based on foods similar to what might have been eaten during the Paleolithic era, which dates from approximately 2.5 million to 10,000 years ago.

A paleo diet typically includes lean meats, fish, fruits, vegetables, nuts and seeds — foods that in the past could be obtained by hunting and gathering. A paleo diet limits foods that became common when farming emerged about 10,000 years ago. These foods include dairy products, legumes and grains.

Other names for a paleo diet include Paleolithic diet, Stone Age diet, hunter-gatherer diet and caveman diet.

Purpose

The aim of a paleo diet is to return to a way of eating that's more like what early humans ate. The belief is that the human body is better suited to that type of diet than to the modern diet that emerged with farming.

Farming changed what people ate and established dairy, grains and legumes as additional staples in the human diet. This relatively late and rapid change in diet, according to the hypothesis, outpaced the body's ability to adapt. This mismatch is believed to be a contributing factor to the prevalence of obesity, diabetes and heart disease today.
