Eating fish and other foods rich in omega-3 fatty acids could help people maintain healthy brains as they age as well as protect their hearts, new research suggests. Per this research, participants with low levels of omega-3 fatty acids in their blood had slightly smaller brains and scored lower on memory and cognitive tests than people with higher blood levels of omega-3s.
The researchers then looked at and ranked the level of omega-3 fatty acids in the participants' blood. People who scored in the bottom 25% in omega-3 fatty acid levels were compared with the rest of the study participants. Researchers found that those who had the lowest level of omega-3 fatty acid levels in their blood had lower brain gray matter volume compared with those with higher levels.
Gray matter volume is crucial to brain health. When it remains higher, brain health is being maintained. Decrease in gray matter volume indicates that brain cells are shrinking. The findings showed that consumption of baked or broiled fish on a weekly basis was positively associated with retention of gray matter volume in several areas of the brain. In fact the greater hippocampal, posterior cingulate, and orbital frontal cortex volumes obtained by optimal fish consumption led to reduced risk of contracting MCI or Alzheimer’s by almost five-fold.
The most recent U.S. dietary guidelines—released last year—recommend at least two servings of seafood a week. Some doctors and diet experts recommend that patients consume fish three times a week or take fish-oil supplements so they get enough omega-3 fatty acids to obtain health benefits.
The passage suggests the following about diet and gray matter volume
  • a)
    Regular consumption of foods rich in Omega 3 help maintains gray matter volume for longer periods.
  • b)
    People who eat foods  richer in Omega 3 tend to have higher than average gray matter volume.
  • c)
    It is important to maintain gray matter volume above a certain level to avoid risk of MCI or Alzheimer’s.
  • d)
    Any irregularity in consuming foods rich in Omega 3 would result in reduction in brain gray matter volume.
  • e)
    Once the gray matter volume reduces, it is not possible to increase the same by consuming foods rich in Omega 3.
Correct answer is option 'A'. Can you explain this answer?
