You're listening to TED Talks Daily, where we bring you new ideas to spark your curiosity every day. I'm your host, Elise Hu. Salt, cooking oil, flour. Ingredients that are in most kitchens almost everywhere in the world. Staples that are so basic, and for many of us, they can easily be taken for granted. But social entrepreneur Felix Brooks Church sees them as something else. An untapped way to get essential nutrients to people who might otherwise go without.

If you want to get nutrients into people, the most efficient way isn't to change the food that they eat, but instead to improve the daily food that they already rely on.

A

Felix works on food fortification, which is the practice of adding vitamins and minerals to common foods to increase their nutritional value. It's not new. Think iodized salt or fortified bread. But as Felix shares in his talk, in many parts of the world, the food system still doesn't deliver deliver nourishment to the people who need it. Most kids can have full stomachs and still be missing the nutrients their bodies and brains need to grow.

B

Bellies are full, but full bellies are not enough. If you're only eating that starch, which is often the case, you are literally starving from lack of nutrients. That's why it's called hidden hunger.

He shows how a small device installed in local flour mills is helping to fight hidden hunger at a massive scale and how starting with everyday foods can help millions around the world. And stick around. We caught up with TED guest curator Angus Hervey with more on Felix's work and why this kind of quiet, practical progress deserves more of our attention. That's coming up right after a short break. And now our TED Talk of the Day.

I'm willing to bet that all of us this week ate a meal that contained at least one of these ingredients. Salt, edible oil, flour. No matter where you live in the world, you're cooking with that. That's the foundation of everything we eat. That's why it's called staple foods, and that's why they're so important. If you want to get nutrients into people, the most efficient way isn't to change the food that they eat, but instead to improve the daily food that they already rely on. That's the idea, and that's the idea behind food fortification, something I know a lot about. We probably all benefited from this already this morning and didn't even realize it. If you ate eggs cooked in oil, that oil had vitamin A, had toast, that bread had zinc and iron. Even the salt that you sprinkled onto that breakfast was iodized. This isn't some overly processed GMO. This is simple, safe, proven science. It's about 100 years old, in fact. Malnutrition caused by lack of nutrients has all but disappeared in countries where food fortification works, but only works where the system works. And unfortunately, in many countries in the global south, that system is either broken or non existent. A farmer grows a crop like maize. A miller buys that grain, grinds it into flour. A mother buys that flour, takes it home, feeds her kid. Bellies are full, but full bellies are not enough. If you're only eating that starch, which is often the case, you are literally starving from lack of nutrients. That's why it's called hidden hunger. It's a big one. It affects 3 billion people. And of course, kids suffer most, stunting delayed brain development, lifelong deformities. And today, unfortunately, thousands of kids will die from preventable sickness and illness. But there is hope, and there are some incredible people working on very innovative ways to solve this problem. This is my buddy Kurt in Guatemala. His company, Semilla Nueva, is on the forefront of biofortification, helping farmers to grow nutritious crops from the start. Jahil, one of my board members, based in Kenya. His company, hello Tractor, is connecting farmers with mechanization and digital platforms, increasing yields and livelihoods. It's like the Uber for tractor. Super cool. My other buddy, Gayatri, based out of Rwanda. Her company, Earthenable, is replacing dirt floors in village homes with more sustainable materials, ensuring kids don't get sick and can actually absorb the nutrients they deserve. Different approaches, same mission. So as Kurt and Jahil sit at the farm and Gayathri at the family, where do I fit? Here at the mill, in the middle, between where food is grown and food is consumed. At San Ku, a social enterprise I co founded with David Dotson. The aha moment was if we could build a machine that sits on that green mill and adds nutrients into the flour, we're going to fortify the entire village. And credit to David, who saw this super early over 20 years ago, that although individually small, these mills about the size of a bedroom, collectively, thousands of these mills feed ent nations. And so now, fortification is not a nice to have. It is a basic human right. So with that inspiration, with that vision, I took off to Kathmandu and landed there in 2010 to do just that, to build these prototypes. Over the course of the year, I broke a lot of things. I failed forward, and after a year, I built the one that kind of worked. That year took a big toll on me. That was Rough. I've recovered. So I had the confidence now in something that kind of worked. I thought, well, let me head to East Africa and test it there to ultimately scale across continents. And I landed in Dar es Salaam, Tanzania. And within a matter of days after visiting some mills, I didn't have an aha moment. I had ah, crap moment. Those mills were completely different. And so my machine didn't work there. I had to go back to the drawing board. I spent an entire year on this dirt floor metal shop banging out devices until I had something that could be installed. I covered hundreds of mills across East Africa, literally dragging that machine across borders, meeting hundreds of millers and learning from them and co designing because we knew if it could work here in a village in Nepal, in a village in Malawi, in Tanzania, in Kenya, it could work anywhere. And by 2015, we had our machine, they commercialized it. We call it the Sanku dossifier because it doses and it's super simple, super lightweight, and automates the process of adding life saving nutrients into the flour that people eat every single day. The way it works is simple. The miller adds raw grain into one side. In the dispenser is a condensed powdered form of nutrients. Just think about your daily vitamin. If you were to crush that up, it becomes powder. Exactly the same thing as that raw grain flows out of our machine and into the mill, that loss of weight is detected and automatically triggers a little feed screw to turn and dose a precise amount of premix every single time those nutrients and that grain flow together and get mixed in the actual mill and out comes fortified flour. It's that simple. So we weren't just building a machine, we were also trying to build a company. And there was tens of thousands of mills. So operationally we couldn't have thousands of staff and thousands of vehicles driving around all of East Africa aimlessly looking for mills, trying to figure out which ones to fix. And so again, we turned to technology. We installed SIM cards, just like from your phone, in each and every one of our dosifiers. So real time production can flow through the nearest cell tower to our devices. We know exactly where the mills are, how much they're producing, how much nutrients they're adding. Is it accurate? Does that machine need fixed? That operational efficiency allowed us to scale. And by 2020, we reached our first milestone, reaching 1 million people in Tanzania. It gets better. Right around that time, Mackenzie Scott found us, loved what we did, gave us a big $8 million unrestricted grant. There are good billionaires, trust me. Now her generosity was beyond catalytic. Not just because of the size of the grant, but because what we decided to use it for, we could have easily thrown at our overhead. At our burn rate, it would have been eaten up within three years. But we invested in future. We invested in infrastructure. We hired an all African exec team for leadership and expertise. We built East Africa's first nutrient premix factory to reduce our cost at scale. We further developed the technology and systems for scale, not just to reach a couple million people, but soon tens and hundreds of millions of people. And we built a lot of docifiers, over a thousand scaled throughout Tanzania, expanded into Kenya, and last year into Ethiopia, and grew from reaching that 1 million people to today reaching 75 million people every single day. I told you it was going to get better. So as a social enterprise, we recognize this is a big problem and it's not just our responsibility to solve. And so we're not just trying to build a company, we're trying to build an industry. And we need partners. And we work very closely with the governments in the countries we operate in. We work with them to pass stronger policies mandating fortification. We upskill their labs with better equipment and protocols so they can accurately test flour in the market. We even train their food inspectors and give them tools so they can regulate the entire industry. This is our systems change piece, and this is what's going to get us to truly scale. And so we're about 24 months away from our original goal of reaching 100 million people. And so line of sight is there. And as you approach a goal or achieve a dream, you got to start thinking bigger. And we do have a new vision. This is actually the first time I'm announcing it publicly. We have a new vision that we call the 1010 1. Over the next 10 years, we're going to scale to 10 countries and reach 1 billion people. Any number with a B is audacious. But that is the point. There's a sense of urgency. And within the context that governments now are mandating fortification across Africa and Asia, the system is starting to work. The machine works. The model does, too. And every day I drive to work, I see it in real life. Every day I come home, I see it working as well. This is Leo. Leo's my son and he loves dinosaurs. Just before I flew here, he was telling me about his latest favorite one, the stegosaurus. That's the one with the big plates and the spikes. Leo is autistic, and because of his autism, he has an extreme eating disorder. And for many Years, all he would eat was pancakes. Perfectly round, perfectly brown pancakes, flour. And because of his autism, he was wasting away in front of us, completely non verbal, aloof. And so my wife Leah, she actually works with us. And what she did is the obvious thing and the simple thing. She added the vitamins and minerals that was missing from Leo's body into that pancake mix. It didn't change the look, the taste, the color. That's how fortification works. It's invisible. But the results were extremely visible. He got strong, he woke up, he started to speak. This is a kid a couple years ago, couldn't say a single syllable. Now he's teaching me about the stegosaurus, right? Trust me, there is.

Thank you.

B

There is a long, long journey. Speech therapy, food therapy, special tutoring. He's got a team, he needs a team. But it's been an absolute privilege to witness what a simple thing like adding vitamins and minerals to a kid's pancake, how that can change his life. Think about what that can do for millions of other children. Leo finally went to school last year, and as of very recently, me and Leah are proud parents of a graduate. It's kindergarten. It's kindergarten, but it's the first step. It's a milestone. We'll definitely take it and we're very proud. And to watch him grow has been amazing. 3 billion people suffer from this hidden hunger. And so this is not somebody else's problem. This is all of us. Thank you.

You were listening to Felix brooks Church at Ted 2026. And now here's journalist and TED guest curator Angus Harvey with some behind the scenes stories on Felix and why this idea matters right now.

C

My name is Angus Harvey. I was one of the guest curators for Ted in 2026. And when we were thinking about people that belonged on the TED stage, one of the first names I thought of was Felix. I first came across his work a few years ago and I was struck instantly by both the simplicity and elegance of his solution. These incredible machines, these dossifiers, but also the power and impact of what they're doing in the world and the incredible reach that he and his team have managed to achieve. It's one of my favorite hidden stories of progress in the world right now. Something that addresses a problem that most of us don't really know about or aren't aware of and yet does so in a way that I think is so mechanical. That part really strikes me so often. When we think about technology and we think about innovation, we think that it needs to Come in some kind of digital form, or you just chuck AI at it. But the Dos fire is such a mechanical thing, and yet it is able to reach so many different people. 75 million people and climbing. In working with Felix on this talk, one thing that became pretty obvious to me early on was that he's got a really great answer to the question of how do you change the world? Is it one person who does it through sheer force of will, the kind of archetypal hero of so many of our stories?

A

Or.

C

Or is it systemic change, something that hundreds, maybe thousands of people need to work on? And the beauty of Felix's story is that the answer, of course, is both. I don't think there's any doubting his force of will. I remember him telling me stories of how in the early days with Sanku, he literally had to drag those machines across borders and through sand and physically manhandle them around the African continent, demonstrating them to various different stakeholders. But I think what's perhaps even more powerful is how he talks about how he's part of a bigger, systemic change, that there are so many people working on this problem, and that he and they are thinking all the time about how they plug in and how they support and are a part of the bigger effort. What I wasn't expecting when we started this process was to hear his personal story. And it strikes me as almost mystical, Something, perhaps, that belongs to belief in some kind of bigger power. How is it possible that a person sets out more than a decade ago to solve a problem for the world, and then it turns out that that solution was something that they needed in their own household? And yet it turns out that that was the exact solution he needed as a father for his son. I don't know how you explain that, but I think those kinds of moments and those kinds of stories are what makes TED so incredible. And I'm so thrilled that the TED community and the millions of people that belong to it have had a chance to hear that story. And I was really honored to play a tiny part in helping that to happen. There is something about Felix that I think you can probably detect both in his voice and in the way he conducts himself on the stage. Something that you can sense. And that thing is congruence, that the story that he is telling himself inside is the same as the story that he is telling the world on the outside. And it also matches up to his actions. I think that people like this, they're not performing for us. They're here to tell us a story. And Those are my favorite types of people. And ultimately, I think those are the people who are the greatest force for good in our world.
