Best-case scenario, says Frame, "these supplements don't work because they don't provide that beneficial antioxidant property." But, she says, there's also a risk they may increase inflammation in the body. Bodily inflammation has been linked to a slew of health issues, including heart disease, type 2 diabetes and some forms of cancer.

In fact, it may lead to digestive discomfort, such as burping, indigestion or diarrhea," she says. "Over time, the consumption of oxidized fats may contribute to cellular damage and inflammation."
