You can now use your pretax dollars to pay for certain types of healthy foods, gym memberships and even fitness trackers.

Health Savings Accounts (HSAs) and Flexible Savings Accounts (FSAs) allow you to set aside money on a pretax basis to pay for “qualified medical expenses,” including medical, dental, prescription and vision bills. But many people don’t realize they may be eligible to spend the funds on a range of other options, including certain meal kits, gym memberships, protein powders, supplements, fitness trackers and even saunas.
