Q. I want to know if you eat avocados and, if so, how does that benefit your brain? And do you use avocado oil for frying?

A. I am certainly willing to share what I do; however, that does not indicate that I am recommending what I do for you or anyone else. The brain and body both need some fat and I prefer to use healthier plant-based fat such as olives and avocado.  I put about 1/4 of an avocado in my morning smoothie every day that I am at home. (I don’t carry my Nutri Ninja with me when I travel, so in that case I try to eat a couple slices of avocado every day, if I am in a country where they are easily accessible.) Studies at Tufts University suggest that avocado can contribute to brain health as well as brain function. Avocado is said to be high in lutein, a substance that is linked with better memory and cognitive abilities. Avocado is also touted as a replacement option for animal-product cheeses, and can add a similar texture to sandwiches, burgers, and even some casseroles.

Typically, I eat my salads undressed or with a little balsamic sprinkled on them. Since fried and stir-fried foods are not on my menu, I do not use avocado oil, although it is touted as one of the healthier oils. I prefer to eat the avocado itself because of the fiber and many nutrients it contains such as potassium, antioxidants, and an anti-inflammatory substance. As far as “vegetable oils,” I read labels carefully and avoid those products (except for cold-pressed extra virgin olive oil). The fallout from the extraction process for many of these other vegetable oils is something I choose to avoid.
