Final answer:
The three types of fats are saturated, monounsaturated, and polyunsaturated fats. Monounsaturated and polyunsaturated fats are considered good for health, while saturated fats are seen as bad. Trans fats, though not one of the primary three, are also considered unhealthy.
Step-by-step explanation:
The three types of fats are saturated, monounsaturated, and polyunsaturated fats. The fats considered good for health are monounsaturated and polyunsaturated fats. These include fats from plant sources like vegetable oils, olive oil, nuts, and certain fish such as salmon. Monounsaturated fats have one carbon-carbon double bond, making them liquids at room temperature, like olive oil. Polyunsaturated fats, which include essential omega-3 fatty acids, have multiple double bonds, like those found in canola oil.
On the contrary, saturated fats are regarded as bad fats. They are mainly found in animal products like meats, whole milk, and eggs and should be consumed in limited quantities as they can increase cholesterol levels and the risk of heart disease. Saturated fats consist entirely of carbon-carbon single bonds, and they are typically solid at room temperature like the fats in lard and butter.
There is also another type of fat called trans fats, which are artificially produced and considered unhealthy. The correct answer to the multiple-choice question is B. Saturated, unsaturated, and trans fats; good: unsaturated, bad: saturated and trans.
