Salad is a healthy food. Spinach, romaine lettuce, spring greens, arugula and kale are all packed with nutrients and very low in calories. As such, a person can eat a boatload of salad for very few calories. So, most people who are trying to be healthy make it a point to eat from the salad bar when they go out for lunch or dinner. In theory, this is a wonderful idea. In practice, salad bars are nutritional disasters. Most salad bars are dedicated largely to the toppings you can put on your salad. These toppings often destroy any nutritional benefit you would receive from eating a salad.
Between bacon bits, candied nuts, dried fruit and cheese, your “healthy” salad is no better for you than a plate of fried chicken and potatoes. Salad bar salad dressings only make things worse. Healthy salad dressings tend to be based on olive oil and various flavors of vinegar. Salad bar salad dressings tend to be made with cream and other fat-heavy ingredients. Do not be fooled by the “low-fat Italian dressing” either. It is likely still very high in calories and packed with preservatives.
