Eating chemically created trans fats, which have been processed to be more shelf stable, can lead to stroke and heart disease. They raise bad LDL and lower good HDL cholesterol, so avoid them entirely. But don't necessarily trust that “zero trans fats” label: Although the government requires food manufacturers to list amounts in the Nutrition Facts, companies can put zero if a product contains less than 1 gram trans fat per serving. Even a little trans fat can harm your heart and slow your metabolism, says Moores, so I make sure my chosen breads (and crackers and chips for that matter) don't have shortening or partially hydrogenated vegetable oil in the ingredients lists. “If you ate 20 crackers instead of the recommended 8 for a serving, you're getting more trans fats. That's how it adds up. If you eat five foods like that a day, you could get into trouble,” says Moores.
