I come bearing an olive branch in one hand, and the freedom fighter's gun in the other. Do not let the olive branch fall from my hand.
Increase your consumption of healthful fats like extra virgin olive oil, avocado, grass-fed beef, wild fish, coconut oil, nuts and seeds. At the same time, keep in mind that modified fats like hydrogenated or trans fats are the worst choices for brain health.
I made lemon spaghetti in an early season of 'Everyday Italian,' and to this day people still come up to me and say they love it. It's very, very simple. Basically, you cook the pasta and mix together Parmesan cheese, olive oil, lemon juice and zest and pour it over the pasta.
I eat nothing that's processed or refined - no high-fructose corn syrup, no sugar, no trans-fats. I eat a lot of fish and monounsaturated fats from olives, olive oil and nuts. A lot of organic, fresh fruits and vegetables. No bread. No gluten. No wheat. No rice.
I always have a good quality extra virgin olive oil. A cheap quality oil will end up cheapening your dishes. And I love sweetening my dishes with maple syrup. It has a bit of a bitter kick at the end that works wonderfully in savory dishes.
