I’ve seen the impact of changing diets as I’ve worked throughout the region. A surprising number of friends and colleagues here have high blood pressure or diabetes. These health issues technically are manageable, but in places where medical care is expensive and less available than in the West, chronic diseases can quickly get out of control.

Local fare where I live in Dakar is healthy — fish, tomatoes, onions, okra, juicy mangoes with peach-like flesh and a grain similar to quinoa called fonio. Popular dishes around here include thiebou djeun, a fish dish served with rice, and mafe, a meat stew cooked with peanut butter and tomato sauce.

Our three kids, who all were in elementary school when we arrived, thankfully never have been particularly picky eaters and tried the new food with gusto. But they are happiest eating food familiar to them: pasta, salads, hummus, chicken and the like. They stay healthy playing soccer and swimming. My husband and I try to keep up with the local cult of exercise in Dakar that sends masses of people running and doing push-ups along beaches and roads. But even here in a city where so many value exercise, noncommunicable diseases are on the rise.

Lately, more shacks selling burgers and fries have been popping up around town. And a lot of food prepared in homes and restaurants has two key ingredients: fatty palm oil and high-sodium flavor cubes.

At home, we’re trying to eat healthy and even flirting with vegetarianism. We don’t use palm oil or flavor cubes in our cooking. We try to load up on as many local fruits and vegetables as we can. So far we’ve resisted the siren call of Africa Fried Chicken.

But I’d be lying if I didn’t admit that deep down we crave the American food — packaged, processed, sugary and fast food — that we tried to limit in our daily lives when we were living in the United States: McDonald’s French fries, Dairy Queen sundaes, hot dogs, Milk Duds, Cheetos and so on.

My husband recently asked our kids what present they’d like him to bring back from a work trip to New York. Their top request: Kraft Macaroni & Cheese.
