First, here's the healthy eating guidelines in a nutshell. They're pretty simple, really.
You can think of this as adding highly nutritious food and decreasing junk food.
Nutrition experts are often at odds with each other, but they all agree on eating more produce.
Each kind of fruit / vegetable contains unique nutrients. Some contain powerful antioxidants or high amounts of enzymes.
Studies demonstrate that healthier people eat more servings of fruits and vegetables.
Foods in their natural state retain the complete set of nutrients given by nature.
Refined salt is the ordinary table salt available in the supermarket; the refining process removes healthful minerals that remain in unrefined salt.
Some healthy fats: olive oil, butter, coconut oil, avocados, nuts, flax seed oil.

Some unhealthy fats: trans fats (partially hydrogenated oils), margarine, commercial salad dressing, refined vegetable oils.
A superfood has concentrated nutrients, often nutrients that aren't available in other foods!
Many kinds of foods can be superfoods: exotic fruits, berries, green drinks such as wheatgrass juice, seaweed, herbs, and healthy fats.

Eat more foods that are extracted, cultured, or otherwise prepared with traditional methods, rather than with modern industrial food processing methods. An example is traditionally-made (not commercially made) sauerkraut.
If possible, eat more organic foods. Organic foods can be found at natural food stores and health food stores, but also at Wal-Mart, many supermarkets, and online stores.
Eat less of the processed food found in the supermarket in boxes, bags, jars, and cans. These are foods manufactured in industrial facilities and engineered to have a long shelf life. They typically are labeled with a long list of chemical-sounding ingredients. For examples, see this list of processed foods.
Read ingredients lists on food labels, and eat fewer foods with unhealthy food additives.
The most harmful ingredients include:
Not every healthy food is good for everybody.

Michael Pollan, a professor of journalism, frequently writes about the Western diet and the American food production system. His healthy eating guidelines, in this New York Times Magazine article, Unhappy Meals, begin simply, "Eat food. Not too much. Mostly plants."
The food he refers to are whole foods. "Don't eat anything your great-great-grandmother wouldn't recognize as food," he writes. He ends his article with nine healthy eating guidelines on choosing and enjoying food.
Pollan's book In Defense Of Food expands on this article.
Weston A. Price was a dentist and researcher who documented traditional diets. The Weston A. Price Foundation is dedicated to traditional foods and traditional farming methods.
