Fish and long-chain ω-3 polyunsaturated fatty acid (LCω3PUFA) intake in relation to the risk of cardiovascular diseases have been well studied. However, studies that directly link fish consumption or LCω3PUFA intake to the risk of metabolic syndrome (MetS) are sparse and the results are inconsist...

BACKGROUND: Supportive interventions for enhancing dietary intake in malnourished or nutritionally at risk adults are frequently recommended. A recent systematic review of randomised controlled trials identified limited and poor quality evidence to support their use. Observational studies have be...
