Toilet paper isn't necessarily better when it's whiter—it's best to choose products made from pure wood pulp, which naturally has a faint creamy-yellow hue.

Currently, most mid- to low-end toilet paper on the market is made from recycled printed materials and white paper, which require ink removal during production and often contain brightening agents and fluorescent whitening agents. These additives offer no health benefits, so it's advisable to avoid overly white paper products.
