A popular trend making headlines is the Paleolithic (Paleo) diet, also called the “Caveman” or “Stone Age” diet. This diet is based on the belief that if we eat like our ancestors did 10,000 years ago, we’ll be healthier, lose weight, and have less disease. The table below compares the Paleo diet recommended intakes to the 2010 Dietary Guidelines and the typical Western diet.
The Paleo diet promotes a higher intake of protein and fat. The carbohydrates included with the Paleo diet are not from grains, but rather from fruits and vegetables (not including white potatoes or dry beans). The 2010 Dietary Guidelines recommends eating carbohydrates from grains, fruits, dairy, and starchy vegetables. Excluding key food groups like dairy and grains makes it likely that key vitamins and minerals such as calcium and vitamin D, will be missing. Decreasing the intakes of added sugar and process foods have health benefits; however, there is no scientific evidences showing the Paleo diet prevents disease.
Since the Paleo diet omits foods from different food groups (e.g., dairy, peanuts, legumes, cereal grains), its long-term sustainability is questionable. We live in a society where it is not possible to eat exactly as our ancestors ate. You might consider a modified Paleo eating plan like lowering your intake of added sugars and processed foods while eating more fruits and vegetables. Balance is best whether you’re trying to lose weight, gain weight, or stay just as you are.
