One night I sat down to look at one of his online courses and then suddenly realized more than an hour had gone by as I watched John tackle complex ideas in history, biology and other subjects. What impresses me most about John is his courage to ask tough questions—about cancer, the conflict in the Central African Republic, even how giraffes have sex—and then answer them in a way that is entertaining while at the same time super informative. I asked John to come on part of my recent trip to Africa and found he was a terrific traveling companion.
In Ethiopia, we visited health posts helping to vaccinate kids living in remote areas of the country; discussed the challenges of agriculture in Africa with a group of small farmers; and had an amazing conversation about growing up in Ethiopia with students at Addis Ababa University.
At every stop, he asked thoughtful questions about tackling poverty, getting young people involved in philanthropy, and tapping the power of storytelling to change the world. So John, thanks for the great conversations and the company. I bet most people in the U. More fruits and vegetables. Fewer donuts, chocolates, and—my favorite—hamburgers.
Your diet choices are often so limited—both in quantity and diversity—that you can end up shortchanged not just on calories but also essential nutrients, putting you at risk for severe infections, chronic medical conditions, and developmental problems.
In Tanzania, where I just visited as part of my trip to Africa, a typical meal for a poor family is a bowl of cornmeal with boiled vegetables. Meat is a luxury for most families, too expensive to buy except for special occasions. The lack of Vitamin A, for example, is the leading cause of childhood blindness in developing countries like Tanzania. One of the most effective ways to get kids the nutrients they need is to fortify staple foods to make them more nutritious.
