As many people try to improve their diet by cutting down on red meat, fish seems like a good healthy option. However, the sustainability of eating fish has increasingly been called into question. Here, we investigate the health claims and arguments for and against eating fish and explore some alternatives.
Omega-3 fatty acids, which, as research has shown, can have a positive effect on heart health, are present in high concentrations in oily fish, such as salmon and mackerel.
Research indicates these fatty acids can also promote greater blood flow to the brain, which is vital for delivering oxygen essential for brain function. And one study has suggested that omega-3s may have a role in healthy brain agingTrusted Source.
Eating fish may also combat inflammation: a recent study found that regular consumption of fish helped reduce the incidence of chronic inflammatory conditions and may even benefit the immune systemTrusted Source.
