Final answer:
Fatty foods are calorie-dense and avocados are an example of a food that is both energy-dense and nutrient-dense. They are high in monounsaturated fats and contain various essential nutrients. Homemade guacamole is a delicious way to enjoy the health benefits of avocados.
Step-by-step explanation:
Fatty foods are known to be calorie-dense, which means they deliver a high amount of calories per gram compared to carbohydrates or proteins. Specifically, fat has about 9 calories per gram, while carbohydrates and proteins each have about 4 calories per gram. Foods that are both nutrient-dense and energy-dense provide not only calories but also a variety of essential nutrients necessary for health.
An example of a food that is both energy-dense and nutrient-dense is an avocado. Avocados are high in healthy monounsaturated fats, which contribute to their calorie content, but they're also rich in vitamins, minerals, fiber, and phytonutrients. I enjoy eating avocados in the form of homemade guacamole, which I prepare by mashing ripe avocados and mixing in diced tomatoes, onions, cilantro, lime juice, and a pinch of salt. This dish can be used as a dip for vegetables or a topping for whole grain toast.
