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?...
