The famed Nurses’ Health Study out of Harvard (well known for being one of the largest and longest-running investigations into women’s health) found that trans-fatty acids are linked to a significant bump in total body inflammation, especially in overweight women. Trans fats can be found in items including fried foods, packaged cookies, crackers, margarines and more. And buyer beware: “Even if a food label reads 0 grams trans fats, it can still contain less than 0.5 gram per serving, so if you eat multiple servings, you could be eating a few grams,” advises Erin Palinski, R.D., C.D.E. Instead, check the ingredient list for partially hydrogenated oil. If you see this, the product contains trans fats. While you’re trimming the fat, cut back on the saturated variety as well, replacing butter with olive oil and being choosy about your protein sources. “Saturated fat, found in fatty cuts of meat, whole milk and butter, can convert to pro-inflammatory compounds when digested. Instead, aim to eat more lean proteins, such as fish, white-meat poultry and plant-based proteins like beans,” Palinski says.
