Fish is one of the best things we can eat for our health. They’re packed with omega-3 fatty acids. These essential nutrients contribute to healthy brain function and can also support our vision too. What’s more, research suggests that individuals with lower levels of omega-3 are more likely to record age-related cognitive decline.

Fennel is also a fab addition for supporting our health. Fennel is actually a relative of parsley – crunchy and sweet, it’s the perfect companion to many fish recipes. It’s healthy cocktail of plant nutrients like rutin, quercetin and kaempferol make it a powerful antioxidant.  It’s also a good source of anethol, a potent essential oil with anti-inflammatory properties.
