I would like to know what amounts of protein are necessary for pregnant women? I have been eating the Paleo Diet since you introduced me to it. This is my first child. I am finding that my protein and fat requirements are significantly higher than what I usually eat.
Is there any research you could direct me to regarding protein requirements for pregnancy based on trimester?
Great question and I am thrilled you are prgnant! The bottom line is that you probably should increase your fat and carbohydrate consumption, and limit protein to about 20-25% of energy, as higher protein intakes than this may prove to be deleterious to mother and fetus for a variety of physiological reasons.
John Speth (an anthropologist) at the University of Michigan wrote a paper on protein aversion in hunter-gatherer women during pregnancy. Listed below is the abstract: (note the 25% protein energy ceiling!!!)
“During seasonal or inter-annual periods of food shortage and restricted total calorie intake, ethnographically and ethnohistorically documented human foragers, when possible, under-utilize foods that are high in protein, such as lean meat, in favour of foods with higher lipid or carbohydrate content. Nutritional studies suggest that one reason for this behaviour stems from the fact that pregnant women, particularly at times when their total calorie intake is marginal, may be constrained in the amount of energy they can safely derive from protein sources to levels below about 25% of total calories. Protein intakes above this threshold may affect pregnancy outcome through decreased mass at birth and increased perinatal morbidity and mortality…”
Pregnant women should include more carbohydrate and fat (i.e. fattier meats) in their diets and limit dietary protein to no more than 20-25% of their total caloric intake.
