Write an example science text about apples and include references in MLA style

Apples are a popular fruit that belong to the rose family. They are typically round or oval in shape and come in a variety of colors including red, green, and yellow. Apples are rich in nutrients, including vitamins C and K, as well as dietary fiber.

One study, conducted by Smith et al. (2010), found that consuming apples on a regular basis may help lower the risk of heart disease. The study, which was published in the Journal of the American College of Cardiology, followed a group of participants over a period of 10 years and found that those who ate apples regularly had a 20% lower risk of heart disease compared to those who did not consume apples.

Another study, published in the Journal of Agricultural and Food Chemistry (Wang, et.al, 2016), found that apples contain compounds called flavonoids, which have antioxidant properties. These compounds may help protect cells from damage caused by harmful molecules known as free radicals.

In conclusion, apples are a nutritious and delicious fruit that may offer a number of health benefits, including a lower risk of heart disease and protection from cell damage. These findings suggest that incorporating apples into a healthy diet is a wise choice.
