Neuroscientist Dr. David Cox Discusses How Diet Affects Aging and His Daily ‘Superfood’
A neuroscientist and health writer recently shared insights on how our diet can influence aging. Dr. David Cox, author of *The Age Code*, revealed the single ‘superfood’ he incorporates into his daily meals to help slow down the aging process.
During a feature on ITV’s show Tonight, Dr. Cox highlighted the importance of dietary choices for improving quality of life as people age. This discussion comes as the number of centenarians in the UK has doubled over the last two decades.
When asked if it’s ever too late to make meaningful changes to one’s diet, he remarked, “Subtle tweaks to your diet, whether you’re 20 or 90, can still make a significant difference and potentially add many more years to your healthy life.”
Interestingly, although we are living longer, the healthy life expectancy—the number of years a person can live in good health—has dropped to just 61 years for both men and women.
On the topic of food and its impact on aging, Dr. Cox specified certain types of food he makes sure to eat regularly.
“Absolutely, it’s the berries,” he noted emphatically. “Berries have become a crucial part of my diet, especially blueberries and strawberries.”
He went on to explain that these fruits contain natural compounds called salicylates, which help eliminate ‘zombie cells’—damaged cells that linger and could potentially harm the immune system. “Berries are true superfoods,” he added.
If you’re unfamiliar with the term “zombie cells,” Dr. Cox explained that while our cells produce energy from food, they also generate waste, leading to these non-functioning cells. As we age, the accumulation of these zombie cells increases, heightening the risk of disease and mortality.
In his latest book, Dr. Cox explores how diet affects aging at a cellular level.
He also pointed out a concerning trend: more people under the age of 50 are being diagnosed with cancer, which he attributes to a lack of dietary fiber. During an interview on The Pat Kenny Show in Ireland, he noted that many are inadvertently stressing their bodies through poor eating habits.
“We tend to snack or eat too often throughout the day, which creates what I refer to as metabolic stress. Our bodies need time to recover,” he explained.
Along with insufficient fiber intake, Dr. Cox observed that many people consume too many processed foods and not enough whole foods, like fruits and vegetables.
