Frequently Asked Questions
Is whey isolate better than whole-food plant protein for muscle growth?
Whey isolate provides a higher concentration of complete amino acids and faster absorption, which is advantageous for post-workout muscle repair. Whole-food plant proteins support overall nutrition and satiety but often require larger portions or complementary plant proteins to match amino-acid completeness.
Can I use a jarred plant-protein sauce instead of a protein powder?
Yes, a plant-protein sauce like PREGO Plant Protein makes it easy to increase meal protein, but it won’t match a powder for concentrated protein per serving. Use sauces to boost everyday meals, and powders when you need targeted post-workout protein.
Are cashews a good protein source for training days?
Cashews are a nutritious, portable source of plant protein and healthy fats that help with satiety and recovery when food is limited. They deliver fewer grams of protein per serving than concentrated powders, so pair them with other protein sources if you have higher daily protein targets.
