Start with the basic common-sense principle that whole foods in a natural state are best. After all, people have been eating all sorts of whole unprocessed foods for thousands of years, and were much healthier doing it than we are today. So...that means butter is good for you (not margarine), non-refined oils such as coconut and extra virgin olive oil are healthy, there's nothing wrong with the saturated fat in red meat or the cholesterol in eggs...etc. There is plenty of research to back this up--I would recommend "Nutrition and Physical Degeneration" by Weston Price if you're interested in knowing what people traditionally ate before processed foods. He studied isolated groups of people that didn't eat processed foods and compared their diet and health to others of the same tribe or whatever who had started eating processed foods. There were groups that were very healthy living on mainly rye bread and cheese, and others that were healthy living on mostly meat and milk (there are lots of other examples in the book, those are just the two that I can think of right now). He also found that no native groups were vegetarian--all used some animal products.
Then I think the next step is to research how to properly prepare foods--just as some fruit has to be peeled to be edible, nuts and grains need to be soaked to have phytic acid (sort of an anti-nutrient) removed, dairy is much better for you if it is cultured, etc. "Nourishing Traditions" is a great book that covers proper preparation of whole foods.
Also, keep in mind that some of the conflicting info you are finding is either A)sponsored by some sort of special interest group (like studies on the benefits of soy sponsored by soy product manufacturers) OR B)based on improperly prepared foods. For example, pasturized homogenized milk is bad for you. But raw milk, especially if cultured (like yogurt) is very good for you.
Also, to some degree I think each person needs to pay attention to their body and figure out what foods they do or do not do well on. Some people may not be able to handle even cultured dairy, and some people don't do well on grains.
Hopefully this helps and isn't too confusing. Good luck in your search!
