The Healthiest And Unhealthiest Breakfast Foods (Slideshow)

Fabulous with a cup of coffee, doughnuts and pastries are far better as a special treat rather than a breakfast. They are full of sugar, calories, and fat, which can hardly sustain you until lunchtime. Eating a breakfast high in sugar can cause a rise in blood sugar eventually leading to obesity and diabetes. 

Sugary kids cereals are, well, just that — full of sugar and little other vital nutrients. Although they taste great and have fun colors, it's not a good start to the day. They are often full of processed ingredients, empty calories, and lead to nothing more than an energy crash mid-morning.

Although quick and absolutely delicious, a bagel smothered in cream cheese probably isn't the best way to start your day. If you're trying to be more calorie-conscious, opt for a whole grain bagel with reduced fat cream cheese — or better yet, try a nut butter spread instead. 

Check the label on your favorite store-bough granola brand and chances are, it's high in sugar and fat. Try to buy organic and natural brands low in sugar or make your own at home.

Processed meats are high in nitrates, which is linked to certain kinds of cancer. Not to mention, these kinds of meats are full of fat and calories. If you crave protein in the morning, it's best to stick to eggs.

The beloved egg is an all-around winner for breakfast. It's rich in protein and dozens of other essential nutrients. Try eating a hard-boiled or poached egg to avoid added cooking fats and oils. Eating eggs for breakfast can keep you full and focused all morning.

Full of protein and calcium, yogurt is a great breakfast. Try buying plain yogurt instead of flavored, which has added sugar. Drizzle on some maple syrup or honey for a bit of sweetness.

Whole grains offer more nutrients and fiber than refined white bread. Try a whole-wheat English muffin toasted with nut butter.

Packed with fiber, which helps lower cholesterol land regulate blood-sugar levels, oatmeal is a perfect start to the day. Avoid those sugary instant packets and opt to make your own on the stove with low-fat milk and a dash of salt. Stir in some peanut butter and chopped fruit for a healthy breakfast. 

Cereal is sometimes the quickest and easiest breakfast for busy mornings. If you are eating cereal, there are some types to look for. Make sure that there are at least 3 grams of fiber and 6 grams or less of sugar per serving. Also, choose cereals that are made with whole-grams and serve with low-fat milk.
