In this week’s Nutrition Diva podcast, I talk with protein researcher Douglas Paddon Jones about whether or not there’s any benefit to combining complementary plant-based protein sources at the same meal. Contrary to a lot of the conventional wisdom, which claims that it’s sufficient to get all of the essential amino acids over the course of a single day, Dr. Paddon Jones argues that a meal-based approach to protein nutrition will enhance the ability to build and maintain lean muscle tissue.
This doesn’t mean you have to tally up and micro-manage each individual amino acid. The following chart shows how to choose meal components that will ensure complete proteins at a meal.
If you consume only plant-based proteins, you may also want to increase your total protein intake by 10-20% to compensate for the lower digestibility of these plant-based protein.
The Recommended Daily Allowance for protein is 0.8 g per kg of body weight (or 0.36 g per pound). Strict vegetarians may want to aim for a minimum of 1 g per kg (or 0.45 g per pound).
These are these are minimum recommended intakes. Research suggests that there may be benefits to higher protein diets, especially for athletes, the elderly, those recovering from surgery or illness, or during weight loss. If you’re in any of these groups, you might want to aim for something closer to twice the recommended minimum.
