What are the nature of the study methodologies which suggest that "foods" can help the human brain "focus or concentrate" better?
Are these randomized controlled trials, or just observational studies?

Hello Denis,
There may be some RCTs referenced in this paper but I am not sure whether they will be relevant to your question:
G0mez-Pinilla, F. (2008). Brain foods: the effects of nutrients on brain function. Nature Reviews Neuroscience, 9(7), 568-578.
Article Brain foods: The effects of nutrients on brain function
Very best wishes,
Mary
