Have you ever walked into your kitchen planning to drink water, only to find yourself eating a biscuit instead? It probably didn't happen because you were especially hungry . It happened because your environment influenced your decision. Behavioural science has consistently shown that our food choices are shaped by what is most visible, convenient, and mentally accessible. In other words, the foods we see most often become the foods we're most likely to eat. This principle has been demonstrated across research on attention, food environments, and behavioural "nudges," where small changes in our surroundings can produce meaningful changes in eating habits.  Let's look at how this plays out in everyday life. Your Kitchen Is Making Decisions Before You Do Think about your own kitchen. When you walk in, what catches your eye first? The packet of biscuits sitting on the table. The transparent container filled with chin chin. The soft drinks you see every time you open...

Every couple has done it. "I'll have what you're having." It feels like an ordinary decision. One shared dinner becomes a weekly routine. Then the same grocery list. The same takeaway order. Before long, you're eating many of the same foods without giving it a second thought. That's what happens when two lives become one. But scientists are beginning to ask an intriguing question: If couples gradually start eating the same foods, could they also be shaping their gut microbiomes in similar ways? More Than a Shared Plate We often think of eating as a personal choice. In reality, it's one of the habits we share most. Partners influence what food comes into the house, what gets cooked for dinner and what ends up on each other's plates. Over time, these small, everyday decisions can make couples' diets surprisingly similar, a pattern that has been observed in research on spouses and social eating behaviours. Most of us stop thinking about it there. Scie...

Every time you choose what to eat, you're making a decision that calories alone can't explain. For many of us, calories have become the main way we judge food. We compare nutrition labels, choose lower-calorie options, and sometimes assume that foods with similar calorie counts offer similar nutritional value. But that's only part of the picture. Calories matter. They can help us understand how much energy we're consuming and are especially useful when we're trying to lose, gain, or maintain weight. The mistake is assuming that calories tell us everything we need to know about a food. They don't. Calories Measure Energy, Not Nutrition A calorie is simply a measure of how much energy a food contains. It tells you how much fuel your body can get from eating that food. What it doesn't tell you is how much nutrition comes with that energy. That's an important distinction because your body needs more than energy to function well. It also needs nutrients such ...

Let me tell you something surprising. Have you ever finished eating and said, "Ah, this food is too heavy"? Most of us have . It's such a common thing to say that we hardly stop to think about what we really mean. We assume the food itself is responsible for the way we're feeling. But is it? Scientists have spent years trying to understand what actually makes us feel full. And one study asked a question that sounds almost unbelievable: Can your stomach make you feel full even when there's no food inside it? The answer turned out to be more interesting than most people would expect. A Strange Experiment With No Food at All To answer that question, researchers carried out an unusual experiment . Healthy volunteers swallowed a thin tube with a small balloon attached to it. The balloon was carefully placed inside the stomach, and on different days, the researchers inflated it to different sizes. There was no food. No digestion. Just the balloon stretching the stomach....

When some people think about blood sugar, they think about sweetness. It seems like common sense. The sweeter a food tastes, the more it should raise your blood sugar. But your body doesn't judge food the same way your tongue does. Your tongue notices sweetness. Your body notices speed. That distinction explains why some foods that barely taste sweet can cause blood sugar to rise quickly, while other meals that taste sweeter may have a much gentler effect. Once you understand this, you'll see why how you eat carbohydrates is often just as important as how much you eat. Your Body Has One Job After Every Meal Imagine it's raining. When the rain falls gently, your gutters carry the water away without any difficulty. Everything works as it should because the water is arriving at a manageable rate. Now imagine a sudden downpour. The gutters haven't changed, but the amount of water arriving every second has. Eventually, the system struggles to keep up. Your body experiences s...

Most of us have met someone like her. By three o'clock in the afternoon, she was completely drained. Her concentration disappeared, her body felt heavy and even simple tasks became difficult. What confused her was that she wasn't skipping meals. Breakfast was always on time, lunch wasn't a problem and dinner came later in the evening as usual. Like many people, she assumed the explanation had to be straightforward. If she felt tired all the time , perhaps she simply wasn't eating enough. It's an understandable conclusion. After all, food gives us energy. So eating more should solve the problem. But the human body doesn't work like a car that only needs more fuel when the tank runs low. The relationship between food and energy is far more interesting than that. Every Meal Has a Journey to Complete Imagine you're expecting an important parcel. It leaves the warehouse, travels hundreds of kilometres, reaches your town and finally arrives on your street. Everyth...

When I was growing up, my mum was always calling me into the kitchen. "Come and learn," she'd say.  Most times, I'd find one excuse or another. I wasn't interested. In my mind, cooking was something I could always pay someone else to do, so learning felt like a waste of time. Looking back, I realise I wasn't rejecting cooking. I was rejecting a life skill whose value I simply couldn't see. For years, that decision didn't seem to matter. Then life changed. I started living in places where I couldn't find the meals I had grown up eating. At first, I blamed the food. I complained that it didn't taste right and convinced myself that nobody could cook those dishes the way my mum did. Eventually, I had to face an uncomfortable truth. The food wasn't the problem. I was. I had never learned how to cook the meals I loved. That realisation changed the way I looked at those evenings in the kitchen. I had always assumed my mum was trying to teach me re...

Everybody keeps saying beans are good for your health. So you decide to give them a try. The next time you go to the market, you buy beans. You start eating them more often. Three or four days later, your stomach starts swelling. After almost every meal, you feel bloated. You look at the beans and say, "This thing is not for me." So you stop eating them. Before long, you're back to eating the way you used to because at least your stomach wasn't disturbing you. Many people stop eating beans because they think their body can't handle them. But that's usually not the real problem. Your Body Isn't Used to the Change If you've hardly been eating beans for a long time, then suddenly start eating plenty of them, the tiny organisms living in your large intestine suddenly have a lot more work to do. These helpful organisms feed on some of the fibre and natural carbohydrates in beans. As they break them down, they produce gas. That's why your sto...

You would expect that deciding to eat healthier would make you healthier, but that's not always what happens. In fact, some people start making worse food choices the moment they become more health-conscious. How is that possible? It often begins with good intentions. After a health scare, a routine medical checkup, or simply the decision to take better care of themselves, many people walk into the supermarket determined to make healthier choices. This time, they're going to pay attention to what goes into their shopping cart. As they scan the shelves, one word immediately catches their eye: Organic. It feels like a shortcut to a good decision. Without realizing it, they relax. They assume they've already found the healthier option, so they move on without asking another question. That small mental shortcut is surprisingly powerful. Why One Positive Word Can Change Your Judgment Our brains are constantly looking for ways to make decisions with less effort. Instead of caref...

When people compare healthy foods, they usually look at what's inside them. They compare calories, fibre , vitamins , minerals, or sugar. If two foods have similar nutrition, it's easy to assume they'll have a similar effect on your appetite. But that's not always the case. Sometimes, two foods with nearly the same nutrients can leave you feeling very different after eating them. The hidden reason has less to do with what's in the food and more to do with the form it comes in. An Orange Shows Why Take an orange. Eating a whole orange takes a little work. You peel away the skin, separate the segments, and chew each bite before swallowing. The fruit stays intact, so eating it naturally takes time. Now think about a glass of orange juice. The peeling, squeezing, and breaking down have already been done. Instead of eating the fruit one segment at a time, you can drink it in a matter of seconds. It's still an orange. Many of the nutrients are still there....

Have you ever finished a satisfying meal, felt completely full, and then found yourself reaching for chocolate, biscuits or cake a short time later? It's easy to assume you've simply run out of willpower. But for many people, that's not the real problem. The cravings themselves aren't the enemy. Stress might be. When Ordinary Snacks Suddenly Become Hard to Resist A packet of biscuits you've ignored all week, a bar of chocolate sitting in the fridge and a slice of cake you weren't even thinking about can suddenly become the only thing on your mind when you're stressed. The food hasn't changed. What has changed is how your brain responds to it. For years, many people believed stress simply made us eat more. Research now shows the picture is more complex. Stress doesn't just influence how hungry you feel. It can also make foods high in sugar and fat seem far more rewarding than they normally do. That's why you can finish a full meal, feel completely...

Many of us blame the ingredients when a smoothie doesn't keep us full. We think it needs more protein or fibre. So next time, we add more groundnuts, Greek yogurt, or chia seeds. Sometimes even another scoop of protein powder. Then we drink it. And we're hungry again not long after. At that point, it's easy to conclude that the smoothie wasn't balanced enough. But the problem isn't always what's inside the smoothie. Sometimes it's what the blender did to it. We've Been Taught to Focus on Nutrients For years, we've been taught to judge food by what's in it. Protein. Fiber. Healthy fats. Those things matter. They really do. But they aren't the only things that determine how filling a meal will be. Your body doesn't respond only to what's in your food. It also responds to how you eat it. That's the part many of us don't think about. Let's Use Groundnuts as an Example Think about roasted groundnuts. You don't throw a whole...

Walk through any supermarket and you'll see foods competing for your attention. "Natural." "Organic." "Superfood." "High in protein." Some come in beautiful packaging. Others cost two or three times as much as similar products. It's easy to assume the more expensive option must also be the healthier one. But that's not always true. The real challenge isn't finding foods that look healthy. It's knowing how to choose healthy food with confidence, even when marketing, price, and labels are pulling you in different directions. That's exactly what the SMART framework is designed to help you do. ▶ Watch the video below to learn the complete SMART method and see how to use it when comparing real foods. Why Choosing Healthy Food Is More Complicated Than It Looks Many people judge a food by its packaging, price, or the claims printed on the label. Those things can be helpful, but they don't tell the whole story. N...

Have you ever bought a meat pie, biscuits, chin chin, shawarma, or a bottle of soft drink and wondered: "Why did I do that?" Many people blame themselves when this happens. They tell themselves they need more discipline. More self-control. More willpower. But modern psychology suggests something different. For many people, the real problem started hours before they bought the food. Understanding why can make healthy eating much easier. Your Brain Changes as Hunger Grows Imagine that your brain has two competing priorities. One focuses on your long-term goals. It wants you to make choices that are good for your health. The other cares only about solving one problem: "I'm hungry. Find food now." Right after you've eaten a satisfying meal, your long-term thinking is easier to follow. Walking past snacks doesn't feel difficult. You simply aren't interested. But then the hours pass. You become busy. You skip lunch . Your hunger grows. ...

For a long time, I thought lunch was the problem. Every workday, the same pattern repeated itself. I'd finish eating, glance at the clock, and almost immediately begin fighting the urge to sleep. If I still had a few minutes before my lunch break ended, I'd rest my head on the table and steal a quick nap before returning to work. What puzzled me wasn't that I became sleepy. It was what happened around me. The colleagues who had eaten beside me were already walking back to work. Some continued chatting as they left the canteen. Others went straight back to their desks and started answering emails. The strange part? We had often eaten the same lunch. Yet somehow, they returned to work feeling refreshed while I felt like I hadn't slept in days. It didn't make sense. My Failed Experiment Convinced that I was simply choosing the wrong foods, I decided to stop making my own lunch choices. Instead, I copied my colleagues. If they ordered rice, I ordered rice. ...

Most discussions about nutrition begin with food. We ask whether a meal contains enough protein, vitamins, or minerals . We compare diets, discuss supplements, and debate which foods are healthiest. Those are important questions. But they all begin surprisingly late in the story. A more fundamental question is this: Where do the minerals in our food come from? Plants Don't Make Minerals A plant can make sugars from sunlight through photosynthesis. It cannot make calcium. It cannot make iron. It cannot make magnesium. Those minerals already exist in nature. So how do they become part of our food? Before a plant can absorb them, they must first be released from minerals, recycled from organic matter, carried through water, and made available to plant roots. A plant cannot do that on its own. That is where the real story begins. The Hidden Work Beneath Our Feet Healthy soil is far more than a place where plants anchor their roots. It is a living system. Tiny organisms release and recy...

A few weeks ago, I shared a simple rule of thumb with my audience: If your grandmother would recognize it as food, eat more of it . It wasn't meant to be a perfect rule. It was a mental shortcut. Nutrition advice has become so complicated that many people don't know where to begin. Every week there's a new superfood, another ingredient to avoid, or a new diet claiming to have the answer. I wanted to give people a simple filter. If a food still looks like something your grandmother would recognize, a sweet potato, beans, eggs, fresh fish, tomatoes, millet, oranges, it's probably a better choice than something that has been heavily reformulated into a product with a long list of ingredients. Then a viewer asked me a question I couldn't answer immediately. "Nsima, I understand your framework. But I now live in a different country with a completely different food culture. My grandmother wouldn't recognize most of the foods here. How should I apply your advice?...

A brief moment in a supermarket made me realize that the real problem was never the food. A woman was about to carry the last bag of rice from the shelf. At that same moment, an elderly man stretched out his hand for the same bag. For a few seconds, both of them stood still. The supermarket was brightly lit. Children were moving around with their parents. The cashiers were attending to customers. Everything looked normal. Except for one shelf. It was almost empty. The woman smiled, withdrew her hand and gently walked away. The elderly man put the rice in his basket. That was all. No argument. No raised voices. Nothing dramatic happened. If you were there, you might have forgotten about it before you got home. I haven't. Because that short moment made me think about a question I had never really considered. Why does one almost empty grocery shelf make people feel so uncomfortable? It Feels Like the Food Is the Problem At first, it seems as though the problem is the food. That's ...
