Breakfast foods vary widely from place to place, but often include a carbohydrate such as grains or cereals, fruit, vegetables, a protein food such as eggs, meat or fish, and a beverage such as tea, coffee, milk, or fruit juice. Coffee, milk, tea, juice, breakfast cereals, pancakes, waffles, sausages, French toast, bacon, sweetened breads, fresh fruits, vegetables, eggs, baked beans, muffins, crumpets and toast with butter, margarine, jam or marmalade are common examples of Western breakfast foods, though a large range of preparations and ingredients are associated with breakfast globally.
With breakfast commonly referred to as "the most important meal of the day", particularly for children, some epidemiological research indicates that having a breakfast might lower risk of metabolic disorders and cardiovascular diseases. While current professional opinions are largely in favor of eating breakfast,[4] some contest its "most important" status.
The influence of breakfast on managing body weight is unclear.
