Nutrition is mostly based in the middle of the two extremes; that being between prime health and malnutrition. In that middle there is a wide range of diseases that can be caused and prevented due to changes in diet. Scurvy is a common disease that can result from unhealthy diet. It is important to note that it is not just malnutrition that can cause problems, and that excesses and imbalances also play a large role.
Living a healthy lifestyle is more about what you eat. It's an entire package: What you eat, How you sleep, The air you breathe, How active you are,etc. Taking steps to improve your lifestyle are actually quite simple. Simple differences like taking an apple over a chocolate bar, or biking over walking, are easy to make and can make the world of a difference!
