Which food is most likely to contain all essential amino acids? Foods that contain all nine essential amino acids are called complete proteins, which are the building blocks of protein that our bodies cannot produce on their own. Complete proteins also assist functions like tissue repair and nutrient absorption. While most plant-based foods are not complete sources of all essential amino acids, there are a few exceptions. These 10 plant-based foods contain all the essential amino acids:
1. Nutritional yeast
Nutritional yeast is a plant-based food that contains all nine essential amino acids, making it a complete protein [1]. It is a great source of protein, fiber, and various essential vitamins and minerals. Nutritional yeast is often used in vegetarian and vegan recipes due to its savory, umami flavor and nutritional benefits. Some key nutritional aspects of nutritional yeast include:
- High in protein: 2 tablespoons (5 grams) contain 3 grams of protein
- Rich in B vitamins: Fortified nutritional yeast is especially rich in B vitamins, including thiamine (B1), riboflavin (B2), niacin (B3), vitamin B6, and vitamin B12
- Good source of trace minerals: These include zinc, selenium, manganese, and molybdenum, which are involved in gene regulation, metabolism, growth, and immunity
Nutritional yeast is a versatile ingredient that can be added to various dishes, such as salads, soups, and even popcorn, to enhance the flavor and nutritional value
However, it is essential to choose fortified nutritional yeast to get the most health benefits, as unfortified varieties may not contain sufficient amounts of certain vitamins and minerals.
