ZOE Science & Nutrition

Today we’re talking about fat, a delicious component of our food with a terrible reputation.  

Fats have been broadly associated with weight gain and heart disease until recently.

A mountain of new scientific evidence suggests this is wrong and that it's not as simple as ‘all fat is bad’. Indeed, eating more healthy fat might actually reduce heart disease for many people.  

In today’s episode, Jonathan speaks to Dr Sarah Berry to learn about what science tells us today, whether it is possible to lose weight on a high-fat diet, what oils we should be cooking with, and the different types of fats.

Our transformation into coach potatoes happened in the blink of an eye. Only 100 years ago, most people relied on manual work to make their living. 

Today, things are different. Many of us live our lives in front of a screen. Online shopping and remote work mean some of us don’t need to leave the house at all. So how bad is this for us? 

The answer is now clear: Low levels of physical activity lead to an increased risk of disease and a lower quality of life in older age. However, when we come to the question of what sort of exercise you should be doing, how often, and how much it contributes to weight loss, the answers might surprise you.

In today’s episode, Jonathan speaks to a Human Physiologist to learn about the interactions between diet and exercise and their impact on human health:

There's a condition that leads to an increased risk of heart disease, dementia, and early death that's been affecting people for as long as they've existed. The many symptoms can severely impact quality of life - ranging from headaches and memory problems to anxiety and weight gain. 

This condition affects more than half of the world's population, but unbelievably its rarely discussed and the scientific research that exists on it is limited. 

It's called menopause, and it affects 1.2 billion women worldwide. It's not a disease, but the effects can be just as serious for some women.

Jonathan talks to the British doctor who's working to educate us about menopause and bring the discussion on the topic into the mainstream.

Dr Louise Newson is a GP, menopause specialist and founder of the Newson Health Menopause & Wellbeing Center. Director of the Balance Menopause App and the non-profit Newson Health Research and Education. Founder of The Menopause Charity.

For many of us, it's a ritual to help us wind down after a long day, an excuse to catch up with friends, or a lubricant to an awkward social situation. Alcohol can be delicious, but our relationship with it is often complicated. 

Good times with friends aren’t without sacrifice, and many of us feel the morning after impact of a few too many drinks. For an unfortunate minority, alcohol can lead to addiction and even death. 

What we want to know is, can alcohol ever be healthy? Is any amount of alcohol a sure path to an early grave, or could a glass of red wine be the best thing for your heart health? This episode examines these contradictions to see what the science says. 

Jonathan speaks to two leading scientists to better understand the effects of alcohol:

This plant has been used by human beings for thousands of years with samples found in 5000-year-old pottery discovered in the upper Amazon. The Mayans considered it a gift from the gods and used it in their sacred ceremonies, where it was believed to have mystical healing powers. For the Aztecs, it was worth more than gold and given to their victorious warriors. 

We are talking, of course, about chocolate. Even though our relationship with chocolate spans thousands of years we still can’t agree about it. It seems obvious that something so delicious must be bad for us. Can there be any truth to the claims that chocolate can improve our mood, our health and even our libido? 

Jonathan speaks to Professor Tim Spector, one of the world's top 100 most cited scientists and author of the diet myth, and Spencer Hyman, one of the world’s leading chocolate experts and founder of the craft chocolate business Cocoa Runners.

1 in 5 people suffer from food intolerances, a figure that’s growing each year. As a result, people are eating increasingly restricted diets, removing dairy, gluten and many other foods from their plates. Unfortunately, they end up eating highly processed foods that damage their gut microbiome and lead to long-term health problems. Even with food restrictions, many people see limited improvements in their symptoms.

The whole topic of intolerance is full of pseudoscience, dubious blood tests, and miracle cures.

However, in the last few years, we have seen a revolution in our understanding, with gut bacteria now the stars of the show. This new understanding has profound implications for how we should treat our food intolerances. 

Today we’ll focus on what the latest science says. Jonathan is joined by Will Bulsiewicz, board-certified gastroenterologist, New York Times best-selling author and ZOE's science board member, whose latest book is all about food intolerance.
