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?

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

A simple guide to stop your pen from jamming

If you don’t follow these key steps your pen may jam. A jammed pen is not only frustrating but can waste your medication.

Taking a deep dive into Calocurb

New research is constantly shaping our understanding of food and hunger. One study recently published explores the role of bitter plant extracts, particularly those derived from New Zealand-grown hops. A recent study investigated whether a bitter hops extract (Amarasate®) could influence hunger and food cravings during fasting.1 The findings add to a growing body of research examining how natural compounds interact with digestion and appetite regulation.

How women are conquering weight challenges with Numan

Losing weight can often feel like an uphill battle, especially for women navigating challenges such as menopause and PCOS. Yet Philippa, Sam, Oluchi, and Jessica’s stories show that while everybody’s health journey is different, progress is always possible.

The many faces of depression and how to spot them

Depression is often imagined as a singular, recognisable condition—one that looks the same for everyone. The reality, however, is far more complex. Depression manifests in multiple forms, from persistent sadness to extreme irritability, and even physical symptoms like chronic pain and fatigue.1

How do talking therapies work and are they effective?

Talking therapies, also known as psychological therapies, have become a cornerstone of modern mental health care. Whether it’s dealing with anxiety, depression, trauma, or even chronic pain, these therapies help people navigate their thoughts and emotions in a structured and supportive way.1

How do vitamins and minerals really affect sleep?

March is National Bed Month, a time to reflect on the importance of sleep, which is something that many of us sacrifice in the name of productivity, social life, or just one more episode of our favourite show. But while much of the sleep conversation focuses on bedtime routines and blue light exposure, what we eat plays a surprisingly powerful role in how well we rest. Certain vitamins and minerals act as natural sleep aids, while others—whether from food or drinks—may be keeping you up without you realising it.

The role of muscle in weight loss: beyond the scale

When it comes to losing weight, it's crucial to understand the importance of building and maintaining muscle. Weight loss efforts often lead to muscle loss, which can be counterproductive to achieving long-term health. Strong muscles enhance your body's metabolic efficiency and play a vital role in overall health.1

The obesity paradox: understanding metabolically healthy obesity

While obesity is often a red flag for potential health problems, not everyone with excess weight experiences these issues. Some people are considered "metabolically healthy obese" (MHO).

When you lose weight, where does it actually go?

In the world of weight loss, myths and misconceptions are all the rage. If you've been under the impression that fat is converted into muscle or takes a one-way trip down the toilet, it's time for a rethink.

What’s the difference between generic and branded medicines?

If you’ve ever picked up a prescription and noticed a different brand name on the box than what you expected, you might have wondered: Is this medicine the same? Will it work just as well?

How putting pen to paper can transform mental health

For centuries, people have turned to writing to make sense of their thoughts, process emotions, and gain clarity. Diaries, letters, and even scribbled notes have served as outlets for the human experience. But what if writing isn’t just an emotional release, but a powerful therapeutic tool? Research suggests that writing therapy, known in psychotherapy as structured, intentional writing exercises, can have profound effects on both mental and physical health.1

The science behind teamwork in weight loss

Working together as a team can make a big difference in how successful people are at losing weight, especially when it comes to sticking to diet and exercise plans.

PCOS and insulin resistance: what’s the link?

Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting many women of reproductive age. Characterised by symptoms like irregular menstrual cycles and elevated androgen levels, PCOS is further complicated by a significant metabolic component: insulin resistance.
