What are Complete Protein Foods?
Did you know that there are 20 different amino acids that your body needs to function properly. Yup, it’s true, and they each have different functions. Eleven of those amino acids are produced by the body all by itself. The other nine, often referred to as “essential amino acids,” must come from our diet.
A COMPLETE PROTEIN FOOD refers to a food source that contains all nine essential amino acids that the body cannot produce on its own. Complete protein foods contain all the amino acids our bodies need to build and repair muscles and are like puzzle pieces that fit perfectly together to keep us strong and healthy.
What about Incomplete Proteins?
Incomplete proteins, on the other hand, are proteins that don’t have all nine types of amino acids that you need to get from food. These would include foods like spinach, peas, nuts, seeds, collagen, andwhole grains, like brown rice.
It can, however, sometimes get a bit confusing with certain foods likechia seeds, for example. This is because althoughchia seedscontain all 9essential amino acids, they are still considered an incomplete protein source because, evidently, they must include “enough protein”to be considered a complete protein.
How Much Protein Do We Need?
Have you ever wondered howmuch proteindo we really need? Well, according to the Mayo Clinic Health System, therecommended dietary allowanceto prevent deficiency is 0.8 grams perkilogram of body weight.
Why Are Complete Protein Foods Important When Fasting?
Complete protein foods are ideal for intermittent fasting due to their ability to provide essential amino acids that support muscle repair and growth during the fasting period. When practicing intermittent fasting, the body enters a fasting state, during which it relies on stored energy reserves for fuel. Consuming complete protein sources during the feeding window ensures that the body receives all the necessary amino acids it needs to maintain muscle mass and support overall health and immune function.
Additionally, protein-rich foods help promote satiety. This keeps hunger at bay during fasting periods and makes it easier to adhere to the fasting schedule and ultimately lose more weight. By incorporating complete protein foods into meals during intermittent fasting, individuals can optimize their nutrient intake, support muscle maintenance, and enhance feelings of fullness, ultimately contributing to the success and sustainability of their fasting routine.
