Avocados

Many people avoid avocados because of their high fat content; they believe that avoiding all fats leads to better health and easier-to-control body weight - this is a myth. Avocados are rich in healthy fats, as well as B vitamins, vitamin K, and vitamin E and have a very high fiber content. Studies have shown that regular avocado consumption lowers blood cholesterol levels.

Avocado extracts are currently being studied in the laboratory to see whether they might be useful for treating diabetes or hypertension. Researchers from Ohio State University found that nutrients taken from avocados were able to stop oral cancer cells, and even destroy some of the pre-cancerous cells.
