In the sentence below, I don't understand how the clause after "over and above.." fit into the sentence.
people who eat diets high in processed foods are taking an equivalent of 11, 1-g capsules of linoleic acid daily over and above intake from wholesome foods
Is it basically saying, if you eat a lot of processed foods, it's like taking 11 capsules of linoleic acid (1g per capsule) and this is a lot more than the intake from whole some foods?
what would be a synonym for "wholesome foods"? What does wholesome mean in this case?
