Don't sweat it unless he eats NOTHING. Keep offering him wholesome stuff, lots to drink but no sugars like juices. A healthy body sometimes wants to fast a bit, to clean up inside. Fruit is a good idea in this case. He might be fighting off a cold and his body needs a rest from the work of digestion. If that is the case, then helpful foods would be oatmeal (whole-grain or "long-cooking" rather than the quick-cooking cardboard stuff) with honey (if he's old enough, I don't remember what age that is). And well-cooked fresh foods are easier to digest than raw foods, or canned baby foods.
... another thought - has he been given meat already in his diet? It's better, internally, for kids to NOT have meat or eggs until they're 3, and then to stick with poultry white meat & fish until they're 5. Plus, in this day & age, organic eggs are the only ok eggs once you start to serve them at 5 years.
