I want to clarify this because a lot of people think "neutral" means "tell everybody's side of the story", and this is simply not true. Please refer to Wikipedia's entries on due weight; the term means including all significant viewpoints - either majority (expert) viewpoints or minority viewpoints attributable to prominent experts (not quacks). It also means not taking sides, instead just explaining the viewpoints and sources: "most experts (citation) agree on X, although experts A and B disagree, claiming Y instead."
##Example of NPOV vs. Non-NPOV wording
Question: I am making (name of some baked good) and want to make a healthier version. Can anyone suggest how I can reduce the amount of oil to make this recipe healthier?
Non-NPOV Answer: Oil is fat. You should cut out all that fat completely and substitute it with something like applesauce. That will be much healthier.
Still not NPOV: You can substitute applesauce for the oil, but as long as you are using an oil that's mostly mono/polyunsaturated (such as sunflower oil) and avoiding saturated or trans fats, then it's perfectly healthy already.
NPOV Answer: You can reduce the oil by substituting some of it with applesauce, but reducing overall fat intake does not have proven health benefits. A certain amount of fat is actually necessary in one's diet. Furthermore, monounsaturated and polyunsaturated fats are both known to lower LDL cholesterol (colloquially called "bad" cholesterol), and although it is widely believed that saturated fats increase the risk of heart disease, more recent research has put that into question as well. Very little is actually known for sure about the long-term effects of dietary fat intake and you should be cognizant of this when making decisions about your diet.
Also NPOV: You can reduce the oil by substituting some of it with applesauce. (Period. No health/diet-related information presented.)
