Walnuts have many benefits for your health

Summarised by Dr Ian Sheerin PhD, Senior Lecturer, Christchurch School of Medicine

NutZino is made from walnuts, which contain many elements which are beneficial for your health, including:

Omega -3 - which is good for brain functioning, for heart health, for your arteries, and helps to lower LDL cholesterol (the dangerous type);

Anti-oxidants, particularly ellagic acid, and polyphenols. These are believed to reduce risk of cancer, cardiovascular disease and neurodegenerative diseases such as Parkinson’s and Alzheimer’s disease. Ellagic acid supports the immune system, blocks metabolic pathways that can lead to cancer, and helps to prevent cancer cells from replicating.

Melatonin, which improves sleep, as well as anti-oxidant activity.

Essential amino acids, notably l-arginine. Amino acids form the basis of all proteins. Arganine is beneficial for heart health as it improves the functioning of the arteries by making them more elastic and helping to improve blood flow;

Protein – walnuts are a rich source of protein and are low in saturated fats

Vitamin E – essential for normal cell structure, for formation of red blood cells, protects lungs from pollutant damage and is believed to slow aging of cells.

Manganese and Copper – which are important in promoting anti-oxidant activity.

The US Food & Drug Administration has recently cleared the health claim that:

“eating 1.5 ounces per day (about 43 grams) of walnuts as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease.”
