The Claim

When evaluated using the DIAAS method under in vitro conditions, soymilk and tofu for children aged 0.5–3 years exhibit protein quality scores of 78–91 and are classified as 'good', while cooked soybeans exhibit scores below 60 and are classified as 'low', indicating that processing improves amino acid profile adequacy for young children.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

For children aged 0.5 to 3 years, processed soy products like soymilk and tofu provide better amino acid adequacy than cooked soybeans, as measured by the DIAAS method under in vitro conditions.

See the scientific wording

When evaluated using the DIAAS method for children aged 0.5–3 years, soymilk and tofu have protein quality scores of 78–91, classified as 'good', while cooked soybeans have scores below 60, classified as 'low', indicating that processing improves the amino acid profile adequacy for young children under in vitro conditions.

Why this might work

Making soy into soymilk or tofu removes substances that block digestion and breaks down protein structures, allowing more amino acids to be absorbed in the gut.

  1. Study: In vitro DIAAS of Swiss soybean cultivars using the INFOGEST model: Increase in protein quality from soybean to soymilk and tofu.

    Lab tests show that soy milk and tofu have better amino acids for little kids than plain cooked soybeans, because making them into milk or tofu helps the body use the protein better.
