Whoever told you that is right. Even a new engine has a little bit. The older an engine gets, the more it has. But there can be things that will aggravate this.
-a PCV system that is not hooked up or working correctly.
-too low a thermostat temp or a thermostat that is open all the time or missing.
-short trips where the engine never warms up.
If your PCV system is working, while the engine is running, pull the oil fill cap off(if the PCV valve is in the cap, this test won't work). If you have oil smoke puffing out of the oil fill, your engine is really worn, and you may never get rid of all the foam in the oil.

The "foam" you are describing is the detergent in the oil mixing with water in the oil from condensation or from blowby. Usually getting the engine running at operating temperature will drive off the moisture and make the "foam" disappear. The "foam" is more likely to be seen in the winter time. The detergent in the oil is doing it's job!

Is this white stuff actually in the oil in crankcase or on the filler cap & PCV valve?
If it's not actually in the oil.
Just stop making short trips and always runs it to operating temp for at least 1/2hr.
Winter makes it even More difficult to do so.

Something else to consider could be too much oil or air is getting into the oil by the pump somehow. I would strongly recommend you stop driving it if your getting alot of foam. Oil foam is a crappy lubricant. Check on the oil level. It should be between add and full but no higher than that.
