Key health benefits


  • King of the nuts. Walnuts are richer than most other nuts in polyunsaturated fats. The most abundant one is an omega-6 fatty acid called linoleic acid (1).

  • One of the richest sources of antioxidants. The brown skin of walnuts contains a mixture of potent bioactive plant compounds that include ellagic acid, ellagitannins, catechins and melatonin (2).

  • Good for your heart. Studies show that eating walnuts prevents heart disease by lowering ‘bad’ LDL cholesterol, improving blood vessel function thus cutting the risk of any build-up in your arteries. Their rich antioxidant content also helps reduce inflammation (3,4).

  • May boost brain function. Being rich in healthy fats and antioxidants walnuts are linked to improved brain function and possibly may also slow down the progression of age related brain function impairments (5).

  • May help prevent certain cancers. Walnuts are rich source of phytosterols, vitamin E, ellagic acid and other various polyphenols and so could be an effective part of a cancer-preventative diet (6).
