Today we talk about ways to lessen one's chances of developing dementia, aside from dietary changes. Other than eliminating foods from our diet that may hinder brain function, or adding foods that enhance brain function, what can we do to keep our minds sharp as we age?

The first action step you can take to keep your mind healthy is to physically exercise the rest of the body. By keeping our limbs and muscles active, we are not only enhancing the flow of oxygen throughout our bodies, we're continually working our brains, as well. Every move you make requires a message from your brain to be sent to your muscles. So, the more you move, the more you're exercising that part of your brain.

Jim here... A few months ago, I'd posted an article here on the topic of Cognitive Dissonance. This theme seems to crop up from time to time in questions people ask about the raw foods lifestyle. For example, one new raw fooder recently posted a question in a raw foods forum asking whether other raw foodies had reached a place in their lives at which things changed so much that they felt as though they were living a contradiction. Because this struck home for me, I'd like to reiterate my response, somewhat edited, below.

I'm still working on the dishes that will be served at the upcoming 3-Day Raw Food Spiritual Ashram Retreat (only 2 spots left!). Today, I worked on the Sandwich Fixin's that will be served for lunch on one of the retreat days.

Before we moved to Portland, Oregon, land of all things fresh and organic within walking distance, we had to drive quite a distance to reach the food co-op (the only place that had a good selection of organic produce and other raw food necessities). So, we only went shopping about once a week. It took a lot of trial and error to find ways to keep our weekly produce fresh for about a week.

We learned which fruits and vegetables stay fresh the longest, and which go bad the fastest. Based on this, we stocked the refrigerator accordingly (and used up the produce accordingly, as well). The fruits and veggies that stayed fresh the longest were stored in the backs of the shelves (things like carrots, beets, broccoli, cauliflower, apples, etc.). Next we stored the greens that lasted a pretty good amount of time (like kale and collards). And in the front of the shelves and in the door, we stored the more delicate greens (like lettuces and herbs).

Welcome to Episode FIVE! Today we're focusing on our old friend the WALNUT. Since it's officially fall, walnuts are in season right now. What better time to enjoy one of nature's tasty, heart-healthy treats?

Some health/nutrition summary info: Walnuts provide a great source of protein, fiber, B vitamins, Vitamin E, anti-oxidants to help prevent cancer, and Omega 3s to help your heart and vascular system. They also help lowering your cholesterol and blood pressure, and contain numerous beneficial amino acids and polyphenols (compounds linked with reduced risk of heart disease and cancer).

Yesterday, we covered the concept of "unsubscribing" from unhealthy practices. This was of course based on the common Internet practice of subscribing and unsubscribing to various things like newsletters and email lists. I receive quite a few of these each day, many raw foods ones and many non-raw ones. Among the non-raw, one that has been interesting to me lately is called the Art of Non-Conformity, penned by Chris Guillebeau. Basically, Chris' site chronicles his adventures in reaching his personal goal -- to travel to every country in the world! Along the way, he writes about all sorts of out-of-the-box things, as the blog name implies.

Today, he posted something that is remarkably insightful and applicable to our subject matter here, even though his context was completely different. The entry, entitled simply "Before and After," discusses the drinking water problems in much of Africa, focusing for the moment on Liberia. Atop the piece (the "before" picture) is a muddy water hole, the only source of drinking water for one village. The next picture (the "after" shot) shows a different, very happy village obtaining fresh, clean water from a newly installed well. Chris closes his article with the following quote:

So, did you think we'd forget about Makin' It Monday during Wendi & KDcat's big cross-country tour? Absolutely not! ?While in Salem, Wendi filmed Kerry Matson demonstrating one of her favorite raw recipes -- heck, one of our favorites, too! I'd have to say that raw apple pie is one of the classic raw dessert recipes. Everyone interested in raw should know how to make this! (And anyone who tastes it will soon be interested in raw!)

Jim here... An unusual occurrence prompted this post, and I'm unsure as to whether it's significant. I've talked about some of my favorite non-raw items before -- things that were tough to leave behind as I embarked upon this raw foods journey. I think I covered pizza in a relatively recent post.

Corn chips were another. In fact, after Wendi went 100% raw and I more or less began to follow her dietary choices, I clung to corn chips for dear life for quite a long time. I began eating a LOT of salsa in those days. Sometimes, that would be all I'd eat for lunch -- just an entire jar of salsa and a bag of corn chips (though, by then, I'd at least usually buy the organic ones and, quite often, a baked variety of chips as well).

When I finally decided I'd be better off transitioning to an all raw lifestyle, I figured my love affair with corn chips had come to an end. Farewell beautiful chips, I thought. I'll never forget our delicious crunchy time together. And that was that. I never looked back.

But then, at a local raw foods pot luck, I met a raw chef who had more or less perfected a raw corn chip recipe. Could it be , I thought. Has this delicacy returned to me after all, as though via some sweet culinary destiny? Ahh, my friends, that was a glorious day. Chips and salsa had returned to me in an enlightened raw form. I could enjoy them once again, guilt free. And enjoy them I did -- usually using a local shop's "Peruvian Purple Corn" (a living, sproutable, dried corn product).

Alas, fate stepped in once again. "Thou may partake of these crisps any time thou wishest," fate boomed. "Yet, in order to do so, thou must prepare them thine self using thine Vitamix and requiring an enormous flax-sticky mess with extended clean-up time, and thou must have parchment paper available at all times, and thou must exercise great care and patience in using your Excalibur, for these chips must dry for many an hour before ready."

Yeah, it was a bit of a chore to produce them. So, as the novelty of chip making and eating wore off, I slowly decreased the frequency of going through the messy, time-consuming hassle of preparing them. Until yesterday, it had been literally months since I made a batch. But... we'd ordered a few pounds of the corn from Natural Zing lately, and I found myself with some extra time the other night. So...

Now, I'm going to pause for a minute for a tangent on digestion. I know a great majority of people, it seems, complain of various digestive disorders. As a result, we have many raw foodie specialists schooled in the nuances of food combining. Oddly, I never paid much attention to these discussions, nor offered input on these matters, because they simply weren't relevant to me.

In fact, I likened my own digestive system to some kind of nuclear powered garbage disposal. It didn't matter what I ate; digestion wasn't a problem for me. So, for example, I'd routinely finish off heavy meals, and then follow them with a huge slice of juicy watermelon (a major no-no according to common wisdom). It just never bothered me.I always joked that, even though I'd been raw for ages, I could still probably go eat a Big Mac (not that I would) and be unaffected by it.

So powerful was my stomach acid that, admittedly, I sometimes privately *worried* whether this might mean something was wrong with me. I mean, shouldn't some of the things I was eating make me sick? Was it "good" to not be made sick by what is generally regarded as poor food combining choices? Do people commonly suffer from problems of efficiency as well as deficiency ? I still do not really know the answer to these questions, and suspect the answer is rather complicated, anyway. Fortunately, it doesn't matter now because...

Something finally made me sick!? I'm laughing now about that, but I spent most of the evening in terrible stomach pain after having over-indulged in some of those (in)famous raw purple corn chips.

So, what happened ? That's an interesting question for me. Here are some possibilities: (1) Perhaps my hyper-active digestive system *was* in fact a problem, and now it's beginning to normalize. Perhaps, had I been healthier all along, I would have been made sick by some of my food choices, but now my health is improving!? (2) Perhaps it's a fluke and I simply shouldn't have eaten mass quantities of corn and flax so late at night. (3) Perhaps my body is improving in its ability to communicate with me, and/or that I'm getting better at listening, and that the message here is that corn is not something my body gains nourishment from -- at least, not in this dried-reprocessed-redried form. After all, some leading raw food authorities, like Gabriel Cousens, aren't fans of corn (even fresh corn!).

Oh sure, there may be other explanations (e.g., "a bad batch of corn"). But, I'm actually most interested in #3, above. Even though this is an extreme example (more intense than it needed to be), I'd like to think that I'm getting better at knowing what I'm being nourished from and what I am not. I'd like to think that this is a latent sense that can be developed, much like our ability to know things by feeling and intuition rather via pure rationality all the time.

But, with food, I think it's a matter of inventorying your physical sensations head to toe, and also as a whole. How is the food you're eating making you feel? Do you feel satisfied or still hungry? Do you feel light or is the food sitting kind of heavily? Do you feel energized or dragged down? How's your mental clarity? Do you feel spacey or more grounded? Do you feel noticeably happier or more sad than before? How are all of these things mapping out over time? Is your weight moving in a positive direction for you? Are your illnesses improving? Food is medicine, after all; it has all of these effects and many more!

For now, I think I can safely check purple corn off of my own personal list of foods that make me feel good. I suspect my old assertion about "being able to eat a Big Mac without any side effects" no longer applies -- and maybe this is a good thing. I think perhaps it signals some progress in my journey toward optimal health.

In any case, I think this kind of purposeful introspection is healthy, and something we should all strive to do more often.How about you? Had any similar experiences? What have you learned from them?
