Instead of frying your fish you should always bake it. Steaming your vegetables can help maintain the most nutrients. You should use cream sauces or lots of butter anymore either. When you eat vegetables, try squeezing lemon juice on them or using your favorite seasonings.
As you make the proper changes to your diet, keep in mind that it takes time for them to become habits. Eating healthy is always great for your body and your lifestyle, especially when it comes to your heart and the prevention of heart disease.
