Are you trying to eat less sugar? If you are, you might have tried a natural sugar alternative.

Stevia, robinia honey, coconut sugar, agave… the list of these table sugar replacements seems to be growing day by day. But what even are these alternatives? Are they really natural? And do they offer us a healthier way of getting that sweet taste?

In today’s short episode of ZOE Science & Nutrition, Jonathan and Dr. Sarah ask: What are natural sugar alternatives, and are they healthier than table sugar?

Decades ago, there were reams of adverts instructing us to drink our milk so we don’t break our bones. But in the decades since, public opinion toward dairy is very different, and the scientific community has largely debunked these ideas. 

Many of the health-conscious among us choose to avoid it altogether. Our reasons range from a belief that dairy leads to inflammation, to acne, or even to an increased risk of heart attack due to high levels of saturated fat. 

But have we fallen into the same trap we often do, bouncing from one extreme to another? Could cutting out dairy mean we miss out on vital nutrients? Or could it hold the secret to a healthy gut microbiome?

Today, Jonathan is joined by ZOE regulars and renowned experts, Dr. Sarah Berry and Prof. Tim Spector.

In this episode, you’ll not only find out whether you should eat dairy or cut it out, but you’ll also hear two leading nutritional scientists try to reach an agreement on how to translate the latest research into actionable advice. And hopefully, they’ll still remain friends afterward.

More than half of women who go through menopause find its symptoms distressing. In fact, 10% leave their jobs because of the burden.

It’s no wonder that a huge selection of supplements claim to relieve menopause’s unpleasant effects. But do they actually work? Which products are backed by clinical evidence, and which are just “menowashing”?

In today’s short episode of ZOE Science & Nutrition, Jonathan and Dr. Sarah Berry ask: What’s the evidence behind menopause supplements?

As we age, our bodies undergo numerous changes, including a decline in muscle mass and cognitive function. For many of us, exercise and diet play crucial roles in maintaining our health and well-being. 

But how can the protein we eat affect our abilities to exercise and stay healthy as we age?

It can be difficult to separate fact from fiction when it comes to the effects of protein. How much do we need? Is it better to eat protein before or after exercise? And what roles do protein and exercise play in brain function?

In today’s episode, Jonathan is joined by Prof. Ben Wall, an expert in nutritional physiology at the University of Exeter. Together, they unpack the latest scientific research on the connection between protein consumption and exercise.

We’ve probably all been reprimanded for eating too fast at the dinner table or suffered the dreaded “itis” from eating way too much food at a family gathering. Our society and the systems we’ve developed to feed it have ballooned to such a point that they easily override our natural bodily systems that tell us when we’ve had enough to eat. 

When nearly 50% of the United States population is projected to have obesity by 2030, can something as simple as changing the speed with which we eat really be an effective tool for weight loss and sustaining a healthy body?

In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: What is eating rate and does it have any impact on our health?

Menopause is a time of significant hormonal changes which can lead to a range of symptoms that can severely impact quality of life for many women. So, a drug that promises to reduce these symptoms is incredibly welcome, but it has been steeped in controversy.

HRT (Hormone replacement therapy) has been widely debated, with conflicting information about its effectiveness, with some suggesting HRT is outright dangerous. In fact, a massive study twenty years ago linked it to an increased risk of breast cancer. As a result, the numbers of women taking HRT plummeted. So should HRT be avoided at all costs? 

In today’s episode, Jonathan is joined by the author of that very study and esteemed Professor JoAnn Manson, alongside Dr. Sarah Berry to explore the science behind HRT.

With the help of ZOE regular Dr. Sarah Berry, they delve into the science behind HRT, empowering listeners to make informed decisions about treatment for symptoms of the menopause.
