Do you think Paleo diets involve eating mostly meat? While how much meat was eaten in that era is debatable, what is known is that they ate a lot of high-fiber fruits and vegetables. Shown below are the estimated daily fiber and energy intake (Eaton et al. 1997). On a 3000 calorie diet it’s estimated that those who lived in the Paleo era consumed 104 g fiber/day. That translates into 3.3 g fiber per 100 calories.
Do you consider yourself a Paleo eater? If so, do you get that much fiber? For example, I average 2200 calories per day. Based on the estimated Paleo fiber intake of 3.3g fiber/100 calories, I should average 66g or more dietary fiber per day. As shown below, my 7-day average for fiber intake is 94g/day.
