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 author’s main purpose in writing the passage is
  • a)
    Describing a research and presenting its findings
  • b)
    Comparing the benefits provided by Omega 3 in regards to preventing MCI or Alzheimer’s.
  • c)
    Discussing the utility of various varieties of fish as a source of Omega 3.
  • d)
    Comparing how the risk of contracting MCI or Alzheimer’s reduces with the corresponding increased intake of fish rich in Omega 3.
  • e)
    Justifying the reason that U.S. dietary guidelines recommend at least two servings of seafood a week.
Correct answer is option 'A'. Can you explain this answer?

Describing a research and presenting its findings

Research Findings:
- The research suggests that consuming foods rich in omega-3 fatty acids could help maintain healthy brains and protect hearts as people age.
- Participants with low omega-3 levels had slightly smaller brains and scored lower on memory and cognitive tests.
- Those with lower omega-3 levels had lower brain gray matter volume compared to those with higher levels.
- Gray matter volume is crucial to brain health, and reduced levels indicate brain cell shrinkage.

Impact of Fish Consumption:
- Regular consumption of baked or broiled fish was associated with retention of gray matter volume in various brain regions.
- Optimal fish consumption led to greater hippocampal, posterior cingulate, and orbital frontal cortex volumes, reducing the risk of MCI or Alzheimer's by almost five-fold.
- U.S. dietary guidelines recommend at least two servings of seafood a week to ensure omega-3 intake.

Conclusion:
- The main purpose of the passage is to describe the research findings on omega-3 fatty acids and their impact on brain health and cognitive function.
- The study highlights the importance of omega-3 fatty acids in maintaining brain health and reducing the risk of cognitive decline.
