This ice cream parlor favorite can easily be modified into a less fattening and more nutritious version. The two main components -- ice cream and bananas -- are both rich in B vitamins, which are effective depression-thwarters [source: Carper]. Bananas also contain high levels of tryptophan. This amino acid aids the body in the production of niacin, which in turn produces serotonin [source: BBC].
Obviously, the ice cream portion of the banana split is the biggest culprit when it comes to sugar and fat content, but ice cream enthusiasts need not forego this popular comfort treat entirely. Modifying your choice makes it easy to include ice cream in the occasional menu. Numerous light or reduced-fat and low-sugar ice creams abound in your grocer's freezer section. And thanks to major strides in the ice cream industry in recent years, low-fat ice cream tastes surprisingly close to its full-fat brethren [source: Magee].
