What are the big lessons we can learn from the data? The obvious one is this: don’t have the fries. Even the smallest serving offers up 1021 kilojoules, which is around 10% of the recommended amount for a physically active adult male. KFC’s large serve is notably larger than the other chains, and covers as much energy as you’d typically need from an entire meal.
If your craving is too great, which venue you choose might well depend on your relative tolerance for fat in general and saturated fat in particular. McDonald’s scores the best on the latter criteria, with a much lower percentage of saturated fat used in its fry production. On the other hand, its overall fat content is the highest of the three chains.
Everyone uses large amounts of salt (and relatively larger amounts for small servings, reflecting the minimum amount that gets doled out after the cooking process). The 245mg in a small McDonald’s serving is the smallest on offer, but still comprises almost half of the recommended daily intake of sodium for an adult male.
