Gates Foundation: The Story of Food

Random thoughts I have while looking at sweet potatoes:

"You'd look great as a plate of fries."

"Honestly, who was the first to decide to put marshmallows all over you?"


"Wait. Are these yams?"

A thought I have never had: This type of potato saves lives.

As it turns out, they might actually do just that.

Welsy Anena's mother is convinced that orange sweet potatoes saved her daughter's life.  

Not in a "thanks for the side dish, I was so hungry!" kind of way. In an actual life-saving way.

Her daughter, Welsy, had been so sick as a baby, and in and out of a Ugandan hospital — sometimes in such serious condition, her mom didn't know if she'd even make it. But when her baby started being fed orange-fleshed sweet potatoes, her health turned around and now she's a vibrant, healthier kid. Whoa.

Her mom's story isn't the only one that depicts sweet potatoes as an edible hero.

You see, Welsy suffered from Vitamin A deficiency — the leading cause of preventable blindness in developing countries. In Uganda, 1 out of every 3 kids under 5 suffers from Vitamin A deficiency, resulting in almost 30,000 child deaths every year. And that's just in one country.

Orange sweet potatoes can help.

While orange sweet potatoes are common in the United States, they are very new in Africa.

For hundreds of years, Africans have had their own version of a sweet potato: white and yellow in color, very starchy and firm, and frankly, a terrible source of vitamin A.

That's a heavy contrast from the type of sweet potatoes we find in our grocery stores in the U.S., where they are carrot-colored and known for their vitamins and nutrients, especially their vitamin A.

Researchers had an idea: If orange sweet potatoes combat vitamin A deficiency, what would happen if they could get communities to eat them instead?

Maybe it could help prevent blindness and death in kids. They're finding out.

For the past 15 years, the International Potato Center (CIP) has been leading the way on introducing the orange-fleshed sweet potato in Africa.

It's been an adventure and easier said than done. Africans initially scoffed at the idea of orange sweet potatoes. No way. The potatoes had a weird texture and weren't what they were used to eating. They were also grown differently from their traditional type of sweet potatoes. All signs pointed to no. Can you blame them?

The research team from CIP took note and developed a starchier version of the orange sweet potato that still contained more vitamin A than other potatoes, but tasted more in line with what Africans were accustomed to.

Once they had the potato how they wanted it, they had to get people to want to eat it.

They created widespread marketing campaigns that, according to Smithsonian magazine, included radio advertisements and visits to villages in vehicles with sweet potatoes painted on the side.

They traveled around the region teaching about the sweet potato's nutrition.

And showed the power of eating them through pictures and words.

They made sure to have a big presence at exhibitions and community-wide events.

Children's songs were written and performed about the potatoes.

The campaign worked. And it's still working today.

Today, the orange-fleshed sweet potato has reached 2.2 million households, which amounts to roughly 10 million people in Africa.

Scientists are super optimistic at the ability to reduce vitamin A deficiency through this new exposure to the potato. They project that by 2023, 30 million children could be saved from blindness and death because of it.

"We have evidence that  eating 125g of orange-flesh sweet potato provides a child the amount of vitamin A required to prevent blindness from vitamin A deficiency," wrote Joel Ranck, head of communications for the CIP, in an email."125g is about the size of one small sweetpotato."

It's no wonder the research team, comprised of Dr. Jan Low, Maria Andrade, and Robert Mwanga from the CIP, and Howarth Bouis of Harvest Plus, just won the 2016 World Food Prize for their work on this initiative. Bravo!

Together they have built new excitement and hope surrounding child nutrition and preventable blindness in the 14 countries where the orange-flesh sweet potato is now available, with more countries to come.

Agnes Amony, a Ugandan farmer told Harvest Plus, "I began feeding my child on these nutritious foods following the knowledge I attained in the recommended feeding practices for children under five. My child began gaining weight steadily and I am in no doubt that these foods have saved my child’s life. I am forever grateful and will never stop feeding my child on these food crops."

Every step counts. Or, in this case, every bite.

A breastfeeding mother's experience at Vienna's Schoenbrunn Zoo is touching people's hearts—but not without a fair amount of controversy.

Gemma Copeland shared her story on Facebook, which was then picked up by the Facebook page Boobie Babies. Photos show the mom breastfeeding her baby next to the window of the zoo's orangutan habitat, with a female orangutan sitting close to the glass, gazing at them.

"Today I got feeding support from the most unlikely of places, the most surreal moment of my life that had me in tears," Copeland wrote.

You could say Marine biologist, divemaster and National Geographic Explorer Dr. Erika Woolsey is a bit of a coral reef whisperer, one who brings her passion for ocean science to folks on dry land in a fresh, innovative and fun new way using virtual reality.

Her non-profit, The Hydrous, combines science, design, and technology to provide one-of-a-kind experiential education about marine life. In 2018, Hydrous produced “Immerse 360”, a virtual underwater journey through the coral reefs of Palau, with Dr. Woolsey as a guide.

Viewers got to swim with sharks, manta rays and sea turtles while exploring gorgeous aquatic landscapes and learning about the crucial role our oceans play—all from 360° and 3D footage captured by VRTUL 2 underwater storytelling VR cameras.


Hydrous then expanded on the idea to develop two more exciting augmented adventures using Meta Quest 2 technology: “Expedition Palau,” a live event where audiences can share a “synchronized immersive reality experience”, which includes live narration from Woolsey, and “Explore,” a “CGI experience” to enjoy the magic of the ocean at home.

“I’ve been extremely fortunate to explore and study coral reefs around the world,” Woolsey said, sharing that it was “heartbreaking” to see these important habitats decay so rapidly while the latest scientific reports did not clearly lead to widespread compassionate action.

“How do we care about something we never see or experience?” she reflected. As she discovered, virtual reality would be a powerful solution for eliciting empathy. “VR has the ability to generate presence and agency and make you feel like you’re there. It's that emotional connection that can bridge scientific discovery and public understanding”

The combination of virtual reality and the ocean’s natural breathtaking beauty is, as Woolsey puts it, a “match made in heaven” for getting people more engaged in ocean education. “When you’re floating you can look up and down and all around you…seeing a school of fish surrounding you and reefs in these cathedral-like structures. Rather than watching a video of a scientist, you get to become the scientist.”

Hydrous also has special kits to provide middle school students hands-on learning about ocean life. In addition to a journal, activity cards and a smartphone VR viewer, each kit includes lifelike 3D printed model pieces of a coral reef so that middle school students can try building their own.

These reef models even turn white when temperatures rise inside the aquarium, which mimics the real “bleaching” that corals endure when they die due to higher than normal ocean temperatures. Students really do become scientists as they figure out how to bring color back to their reef.

While it’s true that the health of our oceans affects us all, the growing threats our oceans face—pollution, overfishing, climate change—don’t always affect us on an empathetic level. Through the use of technology, Woolsey has created an innovative way to connect hearts and minds to one of the Earth’s most important resources, which can inspire real and lasting change.

“We can’t bring everybody to the ocean, but we’re finding scalable ways to bring the ocean to everyone.”

Dr. Daniel Mansfield and his team at the University of New South Wales in Australia have just made an incredible discovery. While studying a 3,700-year-old tablet from the ancient civilization of Babylon, they found evidence that the Babylonians were doing something astounding: trigonometry!

Most historians have credited the Greeks with creating the study of triangles' sides and angles, but this tablet presents indisputable evidence that the Babylonians were using the technique 1,500 years before the Greeks ever were.
