Hello
Have you heard of the Specific Carbohydrate Diet it is close to the paleolithic diet we evolved on but explained in much more detail. Some general guidelines are, no grains (i.e. rice, wheat, corn, oats, etc.), no processed foods, no starchy vegetables (i.e. potatoes, yams, etc.), no canned vegetables of any kind, no flour, no sugar, no sweeteners other than honey and saccharin, and no milk products except for homemade yogurt fermented for 24 hours, prepared according to the instructions in the book.
