Your mother probably told you to eat oatmeal because she wanted you to start off the day with a hot breakfast. Oatmeal has other health benefits, though: eating this food on a regular basis can help to lower your risk of heart disease and diabetes (Type 2 variety).
To get the maximum benefit from the oatmeal, buy the plain variety. The prepackaged type is loaded with sugar, which you don’t need if you are trying to stay true to your heart healthy diet. Instead, choose steel cut oats and add some fruit if you want to sweeten it. Your heart will thank you for making this choice.
