The One Ingredient That's Worse Than Sugar (and Two Others to Watch For) A few reasons to scan nutrition labels carefully. By Emma Haak

The ingredient: Partially hydrogenated oils, otherwise known as trans fats 
What you should know: These types of trans fats are so bad for you that in 2015 the Food and Drug Administration gave food manufacturers and restaurants three years to phase out PHOs. Why? They're known to raise levels of bad cholesterol (LDL) and lower levels of the good ones (HDL). That increases your risk for cardiovascular disease. 

The ingredient: Butylated hydroxyanisole (BHA) 
What you should know: BHA is used in some cereals, chewing gums, potato chips and vegetable oils to keep the oils in them from going rancid. We're all for non-spoiled chips, but according the National Toxicology Program, a branch of the Department of Health and Human Services, BHA is "reasonably anticipated to be a human carcinogen." 

The ingredient: Soybean oil 
What you should know: When mice were fed diets containing either 40 percent soybean oil (unsaturated fat) or 40 percent coconut oil (saturated fat), the soybean-oil eaters gained 25 percent more weight, had fattier livers and greater insulin resistance (a precursor to diabetes) than the coconut oil group, found a 2015 study in PLOS One .
