16 Complete Protein Pairings with Red Bell Pepper

Summary:

  • Red bell pepper is low in protein - about 1.6 grams per large.
  • In addition, red bell pepper provides only 4 of the 9 essential amino acids sufficiently - it is a little low on isoleucine, leucine, lysine, methionine and valine.[1]
  • Red bell pepper pairs well with carrots, pumpkin seeds, hedge mustard seeds, chia seeds or spirulina to create a complete protein profile. [2] More red bell pepper 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 red bell pepper, and found both vegan and vegetarian pairings with red bell pepper 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 Red Bell Pepper

Relatively low in protein, a single red bell pepper contains 1.6 grams of protein, or about 3% of recommended daily values. [1]

To get the adequate amount of protein with red bell pepper alone, you will need 31 red bell pepper (5050 grams) for an average female, or 37 red bell pepper for males. [4] That's over 1310 calories, and a lot of red bell pepper! Pairing red bell pepper with a richer protein source is a good idea.

Essential Amino Acids in Red Bell Pepper

Proportionally, red bell pepper does contain abundant amounts of 4 out of the nine essential amino acids. However, red bell pepper is a little short on isoleucine, leucine, lysine, methionine and valine.[1]

To have adequate amounts of all nine essential amino acids with red bell pepper alone, you will have to eat 87 red bell pepper (14333 grams) for an average person. [2]

That's about 184% more red bell pepper to compensate for the lack of isoleucine, leucine, lysine, methionine and valine, compared to the protein requirement alone.
