Crabs are  low in total fat and saturates, and rich in minerals. Their meat is rich in l-tyrosine, an amino acid that has been shown to help brain power. It contains as much protein as similar weight of lean beef and is therefore ideal for vegetarians who eat fish and seafood. a portion/100g  of crab provides over half of day’s recommended intake of  selenium – a powerful mineral with anticancer action as well as a quarter of a day’s folate.  Folate, sometimes referred to as vitamin B9,  protects against birth defects and is also linked to  a reduction in levels of blood  homocysteine, which is a contributing factor in heart disease.
