Continuing with our week of ways to keep a sharp mind, let's focus on the one widely accepted indicator for dementia or alzheimer's: heart disease. If one wants to dramatically reduce the chances of brain degredation, the first step to take is keeping the heart healthy.

The key advice most health specialists agree on when it comes to a healthy heart is the reduction (ideally eliminatain) of unhealthy fats in the diet. The unhealthy fats are usually seen as solid fats, like butter, margerine, and shortening. However, it's important to not overlook the fats that are also found in meats. By substituting unhealthy fats with something healthier for your heart (like extra virgin, cold-pressed olive oil), as well as transitioning to leaner meats if you are a meat eater, you will be taking some important steps in keeping your heart healthy, as well as your mind.

I've received countless emails over the past few days, thanks to Kevin Gianni's video (below) about the potato pancakes I made for he and Annmarie when they were visiting. In many of the emails you were thanking me for the free eBooks, but some of you had questions (and even some concerns) about sweet potatoes. I've answered you all individually, but I thought it might be a good idea to spend some time discussing the sweet potato a little more. Here's the vid, and then I'll include some of the questions I was asked:

After leaving Salem, Oregon, Wendi and KDcat drove less than an hour to the city of Corvallis where they met up with their hosts the Zander's -- Joni, Steve, Bekka, and Stephanie -- a fellow unschooling family Wendi had come to know in an online forum. It was great to be in their company and we loved them right away,? Wendi wrote. ?Their home is absolutely beautiful on a really cute lot with plenty of plants and trees around ? including the most delightful flowers that smelled divine (I think they were called Daphne).

Corvallis is the city we ve mentioned multiple times -- the city that feels like it s the right fit for us. Well, it lived up to our dreams in just about every way. It s a progressive, hip town with a lot going on. The people are friendly, the weather is beautiful, the land is gorgeous, and there are lots of unschoolers. Access to fresh, ogranic, raw foods doesn't seem to be an issue anywhere in Oregon, according to reports from the road so far. While they've been away, we've talked quite a bit each night about what they're finding -- and fresh organic produce seems pretty much everywhere out west. "The west," wrote Jim Morrison, "is the best." (Surely he was a raw foodie.)

Jon Gold, owner of the Sunny Side Up Cafe (a vegan and vegetarian restaurant there) and an unschool father, put together a little gathering of unschoolers for KDcat and Wendi. They were able to meet some local unschoolers and ask questions. There was also a gathering one day at the cafe where KDcat was able to do some art at a table with some other unschool teens. It's definitely a creative, easy-going town with some fantastic people in it!

Jim here... When you're a committed raw foodie, certain activities that most other people consider routine can become somewhat difficult if you don't apply a bit of forethought and planning. Take traveling, for example -- specifically, flying.

What if you're flying out of town -- say, to the Florida Keys (wink, wink) -- and want to make sure you'll have enough to eat during the day-long trip? What if you also want to bring along some staple raw food items as well ? What if some of these are generally refridgerated ? How can you accomplish all of that?

Continuing on, again, with Wendi s San Francisco travelogue:

After leaving Pete and Blessing, we had a little time before our next meeting. So, KDcat and I explored San Francisco a bit. We saw the largest rainbow flag we've ever seen, experienced the steep hills (much steeper than the ones in Pittsburgh), and checked out an overview spot called Twin Peaks. Our San Francisco host taught us later that evening about how to "curb" your car and always apply the parking brake (which is necessary in a place with such steep hills).

Later we met up with Shivie and Cemaaj, who heard we'd be in town and invited us to visit them for a raw meal? in their home. Wow, what a delicious and beautiful meal we were served! Shivie and Cemaaj are gentle, loving people with a true gift for preparing and serving gourmet raw foods. We were honored to be invited to visit with them and loved them both instantly. They were a lot of fun getting to know, and very generous (sending raw foods with us before we left to eat and share with our San Franciso host). Cemaaj is also a gifted musician and taught KDcat some rhythms on the djembe African drum, which she quickly learned and enjoyed very much! Cemaaj is a gifted teacher and great with kids. It was fun watching him ease her into the instrument, which she now says she'd love to own and practice on!
