About this calculator
The 'Plant Biological Value' calculator compares the quality of plant-based proteins. Biological Value (BV) measures the proportion of essential amino acids absorbed and utilized by the body from a protein source. Higher BV foods like rice (83) and soy (74) are more efficient for body growth and maintenance.
The calculation uses specific values for each plant, considering amino acid composition and intestinal absorption. Wheat, with BV 54, is less complete than rice or soy but still valuable in balanced diets. This tool is ideal for vegetarians, vegans, or those optimizing protein intake.
When using the calculator, remember to combine BV with other sources to cover all essential amino acids. The value may vary depending on food preparation and pairing. Avoid relying solely on BV for long-term nutritional choices.
Frequently asked questions
What does biological value measure?
It measures how efficiently the body utilizes amino acids from a protein source, comparing essential amino acid saturation.
Why does rice have higher BV than soy?
Rice has a more balanced essential amino acid profile and better digestibility, despite being a simple grain protein.
Is this calculator only for vegans?
No. It helps anyone compare the protein quality of plant-based foods, regardless of diet.
How to use this calculator for meal planning?
Combine medium-to-high BV foods (like lentils 16/18) with carbohydrate sources to create complete meals.
Does cooking affect biological value?
Yes. Cooking methods like boiling can degrade amino acids, reducing BV. Preparation impacts nutritional availability.
