16 Complete Protein Pairings with Cornstarch

Summary:

  • Cornstarch is low in protein - about 0 grams per tbsp.
  • In addition, cornstarch provides only 7 of the 9 essential amino acids sufficiently - it is a little low on lysine and tryptophan.[1]
  • Cornstarch pairs well with cauliflower, crimini mushroom, carrots, watermelon or mango to create a complete protein profile. [2] More cornstarch pairings and detailed analysis below.

A complete protein is a protein source that "contains adequate proportions of the nine essential amino acids" that our body can not produce on its own.

World Health Organization [2], National Academy Press [3]

We analyzed the amino acid composition of cornstarch, and found both vegan and vegetarian pairings with cornstarch that creates a complete protein profile. Read on to discover new combinations of foods to enjoy!

Details on how we calculate complete protein profiles.

Amount of Protein in Cornstarch

Relatively low in protein, a single tablespoon of cornstarch contains 0 grams of protein, or about 0% of recommended daily values. [1]

To get the adequate amount of protein with cornstarch alone, you will need 2404 tablespoons of cornstarch (19230 grams) for an average female, or 2885 tablespoons of cornstarch for males. [4] That's over 73270 calories, and a lot of cornstarch! Pairing cornstarch with a richer protein source is a good idea.

Essential Amino Acids in Cornstarch

Proportionally, cornstarch does contain abundant amounts of 7 out of the nine essential amino acids. However, cornstarch is a little short on lysine and tryptophan.[1]

To have adequate amounts of all nine essential amino acids with cornstarch alone, you will have to eat 3563 tablespoons of cornstarch (28500 grams) for an average person. [2]

That's about 48% more cornstarch to compensate for the lack of lysine and tryptophan, compared to the protein requirement alone.
