Walnuts cuts diabetes risk by one quarter

A study of nearly 140,000 women in the US shows regular helpings of a small portion of nuts can have a powerful protective effect against a disease that is threatening to become a global epidemic.

Women who consumed a 28 gramme packet of walnuts at least twice a week were 24 per cent less likely to develop type two diabetes than those who rarely or never ate them.

The latest findings, published in the Journal of Nutrition, are not the first to highlight the anti-diabetic effects of walnuts, with earlier research showing similar benefits.

However, this is thought to be one of the largest studies to find regularly snacking on them can help prevent the condition.

Although the latest research was carried out on female nurses, it's likely that the same benefits apply to men.

According to the charity Diabetes UK, at the current rate of increase, the numbers affected by type two diabetes in the UK will rise from around 2.5 million currently to four million by 2025 and five million by 2030.

Left untreated, it can raise the risk of heart attacks, blindness and amputation. Being overweight, physically inactive and having a poor diet are major risk factors for the disease.

Scientists at the Harvard School of Public Health in Boston, US, tracked 137,893 nurses aged from 35 to 77 over a ten year period to see how many developed type two diabetes.
