When considering a diet that provides an adequate nutrition level, be sure that you are shaking your soy milk before drinking it. This important because all of the calcium and nutrients tend to fall to the bottom of the container and may never be consumed fully. Either way, regular cow milk is a much better way to obtain your calcium intake.
For a healthier diet substitute olive oil for butter. Butter contains high amounts of saturated fats which is associated with high cholesterol and heart disease. Olive oil is much healthier. You can drizzle olive oil, instead of butter, over vegetables. You can also dip your bread, or fry your eggs in olive oil instead of butter.
