Many people try to boost their fibre intake by eating more veg, but not all veggies are high in fibre. You can eat loads of salads + still miss your daily target. Here’s a guide to the veg that pack the biggest fibre punch by @proflaurenball.bsky.social and I

Some vegetables are pretty low in fibre. So which veggies are high-fibre heroes?
Fibre can help prevent overeating and lower your type 2 diabetes risk. But even if you think you eat lots of veggies, you might still not be getting enough fibre.

Gut #microbiome tests are everywhere. Should you get one? medicalxpress.com/news/2025-11... #GutHealth
- Little evidence to support use
- Often associated with sale of unproven supplements
- And even if worked, probably wouldn't change approach (healthy diet, exercise, sleep)!

1/ ⁉Has there been people that kept up with their gut health & still ended up with unwanted diseases like cancer?
Yes, it’s possible for someone to take great care of their gut & still develop diseases like cancer or other illnesses. Gut health is only one part of a much bigger picture.

That’s why it’s vital to make screening a priority.
