Note: All services in AngularJS are singletons. That means that the injector uses each recipe at most once to create the object. The injector then caches the reference for all future needs. Since a Factory is a more powerful version of the Value recipe, the same service can be constructed with it.
A healthy serving size is about 1 to 2 walnuts, per day. To add these wonder nuts to your meal, chop them in your whole grain cereal or make your own walnut butter by blending a few of them with some honey and cinnamon if you wish.
The fiber in walnuts is one of their nutritional benefits. On the flip side, they contain just enough fiber to potentially cause side effects. A handful of walnuts, or about 1 ounce, has nearly 2 grams of fiber, which is 8 percent of the daily value based on a 2,000-calorie-a-day diet, according to NutritionValue.org.
