One of the oldest breakfast options around is oats, which have been on the good list for your health for decades now. Oats are known for being slow-releasing on your blood sugar, which helps to prevent spikes and crashes that can interfere with mood. Oatmeal is also a great option for adding fiber to your intestines, which can help to reduce your risk of certain cancers. In addition, oats are surprisingly a good choice for protein, with a one cup serving offering about six grams of protein. Consider a cup each day for breakfast for best results and if you are looking for a lean option to save on calories then this is a good option.
