Stress and weight: what a health psychologist has to say

Stress: it’s the uninvited guest that shows up unannounced, lingers too long, and disrupts almost every aspect of life, including your weight.

Meat-eaters vs. vegans: how their guts compare

The gut microbiome is one of the most powerful, yet often overlooked, forces shaping our health. It’s a vast ecosystem of bacteria, fungi, and other microbes living in our digestive tract, influencing everything from digestion to immune function, mental health, and even the risk of chronic diseases.1 But does what we eat determine the kind of microbes that thrive inside us? And do meat-eaters, vegetarians, and vegans have fundamentally different microbiomes?

Can your gut microbiome predict your lifespan?

The secret to ageing well might not just lie in genetics, diet, or exercise. It could be in your gut. Scientists are increasingly uncovering how the trillions of bacteria residing in your digestive system influence everything from inflammation to brain health, and ultimately, how well you age.1 Understanding the gut microbiome and its role in ageing could be a gateway for improving longevity and preventing age-related diseases.

Does what you eat affect your stress levels?

Have you ever noticed that when you’re stressed, your stomach feels uneasy? Maybe you experience bloating, indigestion, or even more severe gut issues like irritable bowel syndrome (IBS). This is because your brain and gut are directly connected through what’s called the brain-gut microbiome (BGM) system. Scientists are learning that the trillions of bacteria living in your gut (your microbiome) do much more than help digest food, but also play a crucial role in your mental health.1

How a gut-healthy diet affects your heart

Heart disease remains the leading cause of death worldwide, with millions of people affected by conditions like high blood pressure, high cholesterol, and obesity. While traditional risk factors such as genetics, exercise, and diet have long been recognised, emerging research suggests that the gut microbiome - the trillions of bacteria living in our digestive system - plays yet another important role in the body to help support heart health.1 The latest evidence shows that following a gut-friendly diet can lower the risk of cardiovascular disease (CVD) by influencing cholesterol levels, reducing inflammation, and improving metabolic health.1
