Both diets had the same amount of fat, carbohydrate and protein, but the sources were different, Kavanagh said. The high-fructose group’s diet was made from flour, butter, pork fat, eggs and fructose -- the main ingredient in corn syrup – similar to what many people eat.

By comparison, the control group’s diet was made from healthy complex carbohydrates and soy protein.

IOW all aspects of the diets were different yet the conclusion is that a single component in the "test" diet is responsible for the outcome?

That's a good point. I would have done it with identical diets except the test group got fructose and the control group got an equal amount of glucose. Both are sugars with six carbon atoms.

Non-alcoholic fatty liver disease, aka hepatic steatosis, was unknown before the advent of using high fructose corn syrup in soft drinks.
