FISH is brain food – this has been known for a long time. Now a study has proven with MRI (magnetic resonance imaging,核磁共振成像) brain scans (扫描) that older people who are regular eaters of baked fish during their youth lose fewer brain cells and have better reasoning (推理) and understanding skills. The study was presented recently at the annual meeting of the Radiological Society of North America, according to the Milwaukee Journal Sentinel.
