One Health Tweak a Week Podcast

This week’s One Health Tweak a Week podcast looks at why a healthy grocery trip so often comes home with a few extra foods that were never on the list. Following Helen, a sensible midlife shopper trying to buy food for a reasonably healthy week, we explore how grocery stores quietly reshape what we notice, reach for and justify. The episode looks at oversized shopping carts, fresh produce at the e...

Plant-based meat alternatives have come a long way from the worthy-but-woolly veggie sausages of the 1990s. Today’s burgers, sausages, mince and nuggets can look, sizzle and chew remarkably like meat. But does that make them a healthier choice, or just a more convincing ultra-processed food? In this episode, we’ll explain why “plant-based” is too broad a label to trust on its own. We’ll separate g...

Do you really need to find the “best” fruit, or is ordinary fruit already doing most of the work? In this episode of One Health Tweak a Week , we look at the anxiety created by health blogs, Instagram “super-berries”, and nutrient rankings, then ask a more useful question: how can you get the greatest benefit from the fruit habit without turning it into homework? We start with the bigger evidence:...

Protein supplements are usually marketed at gym-goers, bodybuilders and people chasing bigger muscles. But the people who may benefit most are often the ones least likely to think about using them: older adults, plant-based eaters, people trying to lose weight without losing muscle, and those recovering from illness, surgery or hospitalisation. In this episode of One Health Tweak a Week , we look...

n this week’s One Health Tweak a Week podcast, we’re looking at the form of exercise many health-conscious people still quietly avoid: strength training. A couple of months ago, we talked about why resistance exercise matters for preserving muscle, function, and independence as we age. This episode comes at it from a different angle: not just whether strength exercise helps you stay stronger, but...

This week’s One Health Tweak a Week podcast is about processed meat: not just bacon, sausages and hot dogs, but the everyday foods that quietly creep into otherwise healthy diets. We’ll look at why processed meat is not simply “meat with a bit of salt,” and why regular intake has been linked with higher risks of colorectal cancer, type 2 diabetes, cardiovascular disease, stroke, heart failure and...

This week’s episode is about one of the most overlooked signals shaping your sleep, mood, energy and long-term health: light. Most advice starts at the wrong end of the day. We’re told to stop scrolling before bed, switch on night mode, or buy blue-light glasses. Those things can matter, but they miss the bigger pattern. Modern life has flattened the rhythm our bodies evolved to expect: bright day...

This week, we’re tackling one of the most common reasons people hold back from eating more fruit: sugar. Fruit is sweet. Fruit contains sugar. And if you’re trying to cut back on sugar, it’s easy to wonder whether apples, oranges, berries, grapes and pears should be on the “be careful” list. But whole fruit is not sugar in disguise. In this episode, we explain why “contains sugar” is not the same...

In this episode of One Health Tweak a Week , we look at why time in nature deserves a place alongside food, exercise and sleep as a practical health input. Green space is often treated as a pleasant extra: a weekend walk, a holiday view, a nice background for a phone photo. But studies link regular exposure to nature with lower stress, better mood, improved sleep, lower blood pressure, better self...

Most protein advice focuses on how much you eat. Sometimes it talks about protein quality. But there’s a third question we rarely discuss: when should you eat it? In this week’s episode of One Health Tweak a Week , we look at how protein timing changes the way your muscles respond, especially from midlife onwards. The key idea is simple: your muscles don’t benefit much from a constant trickle of t...

This week’s One Health Tweak a Week podcast tackles a frustrating problem many of us recognise: you try to eat better, cut back on the obvious offenders, and yet your waistline still refuses to budge. The reason may be that belly fat, especially the visceral fat around your organs, is not just a food story. In this episode, we look at the overlooked non-food factors that can quietly drive abdomina...

In this week’s episode, we’re talking about a small shift that could help you stay slimmer, sleep better, reduce reflux, improve your blood sugar, and possibly even support a longer, healthier life. Most of us think meal timing is a minor detail. We focus on what we eat, while barely noticing that dinner has become the biggest meal of the day and is landing later and later. But the research sugges...

In this week’s episode, we look at one of the most underestimated foods for long-term brain health: fruit. Most of us think of fruit as vaguely healthy, useful for vitamins and fibre, but not especially strategic. The research tells a different story. Eating about 200g of whole fruit a day is linked to lower risks of stroke, dementia, depression, and cognitive decline, and much of the benefit seem...

In this week’s episode, we’re talking about a protein problem that gets far less attention than it should: as we get older, it’s not enough to get “some protein somewhere” across the day and assume that will take care of our muscles. We tend to think about frailty as something vague and inevitable. It isn’t. Frailty steals strength, balance, confidence, and independence, and often starts earlier t...

In this week’s episode, we’re looking at what really matters if you want to stay strong as you get older - and it’s not the number on a body-composition scan. We hear a lot about protein, lean mass, and the need to optimise everything. But when it comes to healthy ageing, the more important question is whether you’re staying strong and physically capable. Measures like grip strength and walking sp...

In this week’s episode, we’re talking about visceral fat - the fat packed around your abdominal organs that is much more strongly linked than ordinary body fat to insulin resistance, worse cholesterol patterns, type 2 diabetes, and long-term cardiometabolic risk. Most people assume the best way to reduce belly fat is to diet harder. But when you look specifically at visceral fat, the evidence poin...

In this episode, we explore a question that turns out to be much bigger than sleep alone: what happens when your body clock starts to drift? The starting point is deceptively small. Over the past couple of months, my bedtime slipped by around 45 minutes. On paper, that sounds trivial. In practice, it brought early waking, rougher mornings, and that slightly wired, slightly frayed feeling that sugg...

If you’ve ever looked at a bowl of grapes and thought, “This is basically sweets in disguise” , this episode is for you. This week, we tackle a surprisingly anxious question: does eating fruit every day quietly sabotage your weight and waistline - or can it actually help? We’ll walk through what large, long-term studies really show: people who eat around 200 g / 7oz of whole fruit a day - roughly...

If you’re going to spend money on extra-virgin olive oil, it’s worth making sure you’re not just buying a story on the label. In this episode, we move from why EVOO is such a good health bet to how to actually choose, store, and use it so you’re more likely to get the benefits the studies point to. We’ll look at why “extra-virgin” is a legal grade, not a health guarantee, and why polyphenols are t...

This week’s episode is about extra-virgin olive oil as a small daily habit that quietly pulls several big levers at once . We look at why regular EVOO use keeps turning up in the data alongside lower risk of early death , fewer deaths from heart disease, cancer and dementia , a lower risk of type 2 diabetes and osteoporotic fractures , and slightly better weight and waist outcomes - even though it...

In this episode of One Health Tweak a Week , we zoom out from the protein hype and ask a calmer question: given your age and how you actually eat, how much protein makes sense – and are you anywhere near it? Everywhere you look, the message is “add more protein”. High-protein labels are slapped on yogurts, cereal, bread, ice cream and snacks; fitness feeds throw around magic numbers like 0.8 g/kg,...

If you’re eating pretty well, avoiding sugar-sweetened drinks, and your belt still feels tighter than it should, this episode is for you. In last month’s belly-fat episode, we asked listeners to upgrade just one ultra-processed eating occasion. More than half chose their snacks. That made me curious - and when I dug into the data, it made sense. For many adults, snacks now provide around a quarter...

In this episode of One Health Tweak a Week , we zoom out from individual habits - bedtime, breakfast, evening screens - and look at the bigger system they all feed into: your body’s internal clock. We’ll walk you through what circadian rhythms are, why you have one master clock in the brain and lots of local clocks in organs like the liver and gut, and why health isn’t just about what you do but w...

We’ve been told to eat our five a day for as long as we can remember - but what does the evidence actually say? And how much fruit do you really need to see measurable health benefits? In this episode of One Health Tweak a Week , we look at three decades of data from over 100,000 adults to uncover the surprisingly strong link between whole fruit intake and healthy ageing. We’ll cover why fruit top...

If you’ve ever thought, “I’m already doing quite a lot… surely the only way to get healthier is to overhaul everything,” this episode is for you. This week, we dig into a new Lancet analysis of nearly 59,000 adults that asks a deceptively simple question: what happens when you make small, combined improvements in sleep, movement, and diet - instead of trying to perfect just one? You’ll hear how hi...
