Series 1

In this first episode, Jamie makes sustainable meatballs with two different sources of protein and a smoked salmon omelette with crispy rye breadcrumbs and feta. He also explores the latest science behind how blueberries can help our brain function, putting it to the test, before using them in an unexpected way.

Jamie Oliver celebrates the ingredients that can help the brain to function, starting by serving up a salmon traybake served with harissa-spiced chickpeas and couscous. He follows this up with chicken balls in a vibrant vegetable broth - a dish that includes B vitamins - and spinach and lentil fritters packed with iron - which helps transport oxygen around the body. Jamie also explores the latest science around how fibre can help the immune system, turning one of the best sources of fibre, beans, into a brunch or lunch using crispy filo pastry, egg and spices.

Jamie shows us how eating more healthily can be easy as he serves up delicious Seared tuna with wholegrain rice and a tangy kimchi sauce – a powerful nutritious combo. Next, celebrating cholesterol-lowering oats, Jamie knocks up an impressive selection of overnight oats that take their inspiration from classic desserts. Then he explores the science behind the incredible sleep-inducing potential of kiwi fruit, before he transforms more foods that could help us have a more restful night into a surprisingly healthy dessert.

Jamie celebrates heart-health promoting ingredients, as he makes a nutritious steak dinner and vibrant green orecchiette pasta, and whips up some gnarly gut-friendly oaty balls.

Jamie makes a crowd-pleasing, calcium-rich stew and a fast, flavoursome prawn and chickpea curry, and knocks up one-cup pancakes and a deliciously nutritious hot carrot cupcake.
