Your diet is your best friend to keep you well and healthy: eating either too much or too little can be dangerous. Consuming foods that contain too much salt, sugar or fat does indeed constitute a risk factor for certain diseases, but not eating enough results in deficiencies that can have very harmful consequences on health and well-being. Ideally, you should eat according to the needs of your body, which are different from one person to the next, and what you eat should be varied, in order to avoid deficiencies.
