New research shows the simple lifestyle changes that may protect your gut – and even override your genes.
If you want to live well into your later years, science says there are five simple habits that can make all the difference.
Researchers at Massachusetts General Hospital in Boston have analysed health data from nearly 180,000 people over 50, across three major studies. Their goal? To pinpoint the lifestyle factors that help prevent one of the most common gut conditions affecting older adults: diverticulitis.
This painful condition occurs when small “pouches” form along the colon and become inflamed or infected. It’s one of the leading causes of hospitalisation and emergency bowel surgery in older Australians.
But the good news? It’s often preventable – no matter your family history.
The five keys to better gut health
According to the study, participants with a high “healthy lifestyle score” had a significantly lower risk of developing diverticulitis, even if they were genetically predisposed.
Here’s what made the biggest difference:
- Eating plenty of fibre
- Limiting red meat
- Staying smoke-free
- Maintaining a healthy weight
- Exercising regularly
“Our data provide consistent evidence… that adherence to a healthy lifestyle is linked to a reduced risk of developing diverticulitis, irrespective of one’s genetic predisposition,” the researchers said.
Why it matters
This research isn’t just about preventing diverticulitis – it’s a timely reminder that healthy daily habits can have long-term benefits, no matter your age.
And it’s never too late to start. Whether you’re already ticking off a few of these boxes or just beginning to make changes, every step counts.
