What if a small handful of nuts could help preserve your memory and mental clarity as you grow older? According to new research, that might not be far from the truth.
A team of scientists at the University of South Australia has found that eating nuts regularly can play a significant role in supporting cognitive health. Their findings add to a growing conversation about how diet can help address dementia, one of the most pressing health challenges of the century.
The Numbers Behind the Findings
The study tracked nearly 5,000 Chinese adults over the age of 55 for more than two decades. Researchers discovered that those who ate more than 10 grams of nuts daily — about two teaspoons — had noticeably stronger memory and reasoning skills. Even small amounts, consumed consistently, appeared to delay natural cognitive decline by up to 60 percent over two years.
Why Nuts Make a Difference
Peanuts stood out as the most commonly consumed nut in the study. They are packed with antioxidants, fibre, and healthy fats, all of which are known to protect the brain from inflammation and oxidative stress. Lead researcher Dr. Ming Li explained that such nutritional benefits could help people remain mentally independent for longer, even without a medical cure for dementia.
A Growing Global Concern
China, with one of the world’s fastest-ageing populations, is at the centre of this issue. By 2050, more than 330 million of its citizens will be over the age of 65. Similar demographic challenges exist worldwide, making preventive lifestyle strategies increasingly important.
For millions of families, small dietary changes like incorporating nuts could prove to be a vital step in promoting healthier ageing.
