It was another day of the prosecution calling on witnesses in the $1.9-billion BPI lawsuit against ABC News.
Dr. Kerri Gehring, a professor at Texas A&M shared her finding on nutrition when it comes to Lean Finely Textured Beef, or LFTB, BPI's signature product.
Gehring was retained as an expert by BPI in September 2014.
"Based on my knowledge and based on my work with beef and nutritional analysis that I know beef has nutritional value based on my knowledge and experience with LFTB. I know LFTB is beef so therefore would also have nutritional value," said Gehring.
Gehring further said that every food has nutritional value, it just depends on a consumer's individual needs.
"So is it false to say that dirt is not nutritious?" said Joseph Terry, an attorney for ABC.
"Again, as I just said depending on what was in the dirt, right. And I have not analyzed dirt. I couldn't tell you I do know there's a condition where certain people eat dirt. and I do know that there can be minerals in dirt. So, if I needed that mineral dirt could be nutritious." said Gehring.
Friday, Gehring told the jury that she she told BPI to send samples of LFTB to a lab for analysis to make sure the LFTB in 2015 and 2016 was the same as during the ABC reports.
"I concluded again that LFTB has nutritional value and I concluded that the information provided by these data confirmed the information from before that LFTB is a high-protein, low-fat product." said Dr. Kerri Gehring, a professor at Texas A&M.
The defense asked Gehring if BPI imposed a limit on her testing.
When she said no, they asked her why she didn't test to see if the protein quality of LFTB is similar to meat.
They also talked about nutritional labels on the product.
