Frequently Asked Questions
Can you eat too much protein?
Extremely high protein intake (above 3g/kg) offers no additional benefits and may displace other important nutrients. For most people, consuming adequate protein is a bigger concern than consuming too much. Stay within evidence-based recommendations for your activity level.
Does cooking affect protein quality?
Cooking actually improves protein digestibility for most foods by denaturing proteins and making them more accessible to digestive enzymes. The protein content of foods changes minimally with cooking, and no special preparation is needed to maximize protein absorption.
Is animal protein better than plant protein for muscle building?
When total protein and leucine content are matched, plant and animal proteins produce similar muscle-building results. Animal proteins are more leucine-dense per gram, so those relying on plant proteins may benefit from slightly higher total intake or including leucine-rich plants like soy and legumes.
Should I worry about protein quality scores like PDCAAS?
For people eating varied diets, protein quality scores are largely academic. These scores matter primarily for populations relying on single protein sources or those with very restricted diets. Eating a mix of protein sources throughout the day renders quality scores practically irrelevant.
