The Claim
Wheat-based sausages have the highest total protein content (21.3–24.8 g/100g) among four tested sausage products, but their lysine bioaccessibility is severely limited, with DIAAS values of 33–41%, indicating that high total protein content does not equate to high nutritional quality.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Wheat-based sausages contain more total protein than three other types of sausages tested, but the body can only use a small portion of the lysine in that protein, meaning high protein numbers do not guarantee good nutrition.

Wheat proteins are tightly packed and bound to fiber and other plant compounds, making them hard for digestive enzymes to break down. Special chemicals in wheat block the enzymes that should free up lysine, so even though there is a lot of protein, the body cannot absorb enough lysine to use it for building tissues.
What the research says
1 studyWheat sausages had lots of protein, but your body couldn’t use much of it because they were missing a key nutrient called lysine. So even though they looked protein-rich, they weren’t as nutritious as pork sausages.
