Question: what is the difference between healthy food and unhealthy food?
Answer: Monounsaturated and polyunsaturated fats are the healthy kinds of fats, while saturated and trans fats are the unhealthy kinds. Healthy fats lower your levels of “bad” (LDL) cholesterol and raise your levels of "good" (HDL) cholesterol, while unhealthy fats raise your bad cholesterol levels.
