The Heart-Healthy Power of California Walnuts

From sweet pick-me-ups to comforting crowd-pleasers, California Walnuts are the star of a collection of feel-good, heart healthy recipes for National Heart Month.

Naturally creamy with a satisfying crunch and backed by the UK’s only cholesterol charity, HEART UK, they add flavour, texture and a heart-smart boost to everyday cooking.

Naturally rich in plant-based omega-3 ALA, walnuts are backed by over 30 years of scientific research linking them to a 10% lower risk of cardiovascular disease[1] and a 20% reduced risk of heart disease[2].

Why walnuts for heart health?

  • The only tree nut with significant plant-based omega-3 ALA (2.7g per 30g handful) linked to heart health and healthy cholesterol levels[3]
  • EFSA-approved claim – walnuts contribute to the improvement of the elasticity of blood vessels which is a key factor in cardiovascular health[4].

“When it comes to heart health, consistency matters more than perfection,” says Dr Rachel Blaine, Scientific Advisor at California Walnut Commission. “Choosing ingredients that actively support your heart, like walnuts, is a simple way to nourish cardiovascular health without overthinking meals. Walnuts are a unique source of plant-based omega-3 ALA, and these recipes show how seamlessly heart-smart choices can fit into everyday eating while still being delicious.”

These versatile dishes are perfect for busy weekdays and relaxed weekends, showing just how easy it is to add flavour, texture and health at the heart of your meals. Which one will you try first?
