5. Trans Fats
Trans fats are a component of partially hydrogenated vegetable oil, which can be found in desserts, crackers, pastries, margarine and fast food. Studies have shown trans fats are a greater contributor to heart disease than saturated fats. Consuming too many trans fats can lead to clogged arteries, which can also result in decreased cognitive function. Though the FDA banned partially hydrogenated vegetable oils — which trans fats come from — in packaged food products, it’s still likely restaurants have trans fats in the food they serve.
