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:

Let's stay sharp by learning about brain power! Did you know that the less exercise your brain receives through reading, learning new things (like you do here on our blog!), playing games, and contemplating puzzles the more it is likely to become weak and not serve you well into your centenarian years? Scientists have been trying to figure out ways to improve the brain's function and have learned a lot, but are still uncertain what causes Alzheimer's Disease, or any other form of Dementia.

If you ve ever known someone who suffers with a loss of mental capabilities, you know how sad and sometimes scary that can be. Last week, Jim posted a blog that touched a bit on the subject of Alzheimer s Disease. He wrote in that article, ?I want better than just a small chance that I ll live healthfully for a full lifespan. I want to stack the aging deck in my favor. ?Eating a healthy, raw food diet is something Jim was hoping to use in order to stack the deck in his favor of a life free of memory loss and full of vibrant health.

It's time for a little Phun Phriday Philosophy. (I hope you don't mind a little levity as we end this glorious week ) It just occurred to me that philosophers and self-development gurus commonly admonish against "attachments." Isn't that true ?We're attached to our egos, our possessions, our relationships. All attachments are bad, it is said. I believe one of the primary tenets (Noble Truths) of Buddhism centers on this very thing -- that our attachments cause suffering.

Well, all of that may be food for thought. But, when it comes to food for your body, I'm here to tell you that attachments are GOOD -- especially, when we're talking about the shredder attachment for your food processor!? Oh, don't lie to me, fellow raw foodie (or raw aspirant, as the case may be): You know you've neglected this wonderful tool, haven't you? -- relegated it to some unimportant place in the back of a kitchen drawer somewhere, right ! Well, it's time to rediscover the shredder blade! Your mission, should you choose to accept it, is to reconnect with this delightful food processor attachment.

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?
