First...I understand it talks about the relationship between carbohydrate and serotonin but in the paragraph it does not specifically say carbohydrate "intake" and the production of serotonin isn't it?
It may be a small issue but I think it confused me somehow...
(Or are they the same?)
And just wanted to double check...in the paragraph it says "speeds tryptophan's entry into the central nervous system" is this because there are more trypophan compared to other aminos correct?
And as for other answer choices...
A-although it says about the relationship between serotonin and carbohydrate, it does not provide overview of research.
B-It does not contrast the role of tryptophan and serotonin...serotonin was tryptophan.
C-It's not about how serotonin plays a role, rather how carbohydrate plays a role for influencing the production of serotonin
D-It does not explain this in this paragraph.
Did I see them correctly?
Thank you
