Hi all,

I sent a note to the Okinawa center recently, when I found and tried the famous purple sweet potatoes that provided a major source of food for their Centenarians during World War 2. I've read their book a couple of times, and of course it describes a working program, including eating about 20% less than appetite dictates...that conforms well with Dr. Roy Walford's program. While it doesn't suggest tracking nutrients as such, it does suggest eating a wide variety of vegetables daily, along with small amounts of fish and meat in very small portions, and somewhat more tofu. It's a very interesting and helpful read.

I note that they engage in many activities that could be described as soothing and thus, perhaps, cortisol reducing.

On the other list there was some suggestion that cortisol might be one of the factors that increase lifespan even though excesses seem to be harmful on an ad lib program. I think that speculation is more idle than most, and that Ornish' s use of meditation, yoga, social involvement and reinforcement, and moderate exercise, all of which are probably (yes speculation but more like a good guess) cortisol reducing, the combination of these factors with his diet is part of the reason that his program is successful.

I know that when I follow the entire non-diet program it is much easier for me to adhere to whatever eating program I'm currently testing.

Anyway, here's the reply note from Okicent and my original email.

Hi.

the purple sweet potato is indeed a sweet potato. It has a light skin. Purple inside. It's sticky when baked, and sort of chewy. Glutinous may be a better word. Quite sweet. The taste is something like blueberries....(to me).

As my post noted, I picked them up at Uwajimaya, an Oriental Store in Portland, Oregon...actually, it's probably in Beaverton, rather than Portland. They were expensive, but delicious. I couldn't afford them as a staple, but they make a nice treat. The ones I found were quite small, running from about 3 ounces to perhaps 7 ounces.

I don't have a nutritional analysis of them. I assume that the blue color (and flavor) means (maybe) that they provide some of the same valuable phytonutrient as blueberries and blackberries and all those other blue foods.

Hmmm… I have Uwajimaya around the corner. How

do they call them there? “Purple sweet potatoes”? I’d like to try some.

Here's a little info.

Purple Wild Yam

Purple wild yam also called Dioscorea Japonica or D.alata , it is a kind of

famous peculiar edible mountain vegetable in china , also it grows in some

south-east Asian countries.

According to the scientific analysis report , it contains rich Vitmain B1,B2,

Vc ,Vk, Ca, P, Fe and other mineral elements , the content of protein is two

times of sweet potato, but the fat content is half less than sweet potato,

It also contains rich anthocyanins ( E163) such as ( Cyanidin Acyl Glucoside,

C23H23O+12( 491.427 ) CAS 988395-42-0 ), and digest enzyme , saponins,

mucilage, Allantoin, Choline, Arginine, starch enzyme and so on. In 100g wild

yam, there are 2.7% protein , 0.2% fat , 16% starch , 16% carbohydrate, other

vitamins, mineral elements , iodine and so on, which can nourish the spleen and

stomach, invigorate lung and kidney, replenish the essence of life and stop

diarrhea.

They call them Okinawan purple sweet potatoes. They're in little net bags right next to the rest of the sweet potatoes.

Ha! I thought so.

The Okinawan sweet potato came from China or Korea centuries ago. It was

reserved for royalty, originally.

I'm not surprised to learn that it's high in anthocyanins, since oligomeric

proanthocyanadin is believed to be the potent factor in purple grapes and

blueberries.

This is a cultivated variety. How much it has in common with Dioscorea

Japonica, I don't know. Anyway, it's a good, but expensive, food. I

enjoy them, but at about five bucks a pound, not very darned often.

Note that these are not yams, but sweet potatoes. Although the flavor and

texture is quite different, they are much like the deep red sweet potatoes

mistakenly called yams here in USA, but true yams are sort of off-white,

fibrous, and, to me, not very tasty.
