Re: Tofu linked to mental deficiency (??)

[Guest guest]

Now that is an interesting subject....what is a scarier scenario to each of us as individuals? Dementia is by far scarier to me...as there is long line of alzheimers on my dad's side... but very little cancer.

[Guest guest]

this is the same study often mentioned here and discussed by Walford in his

book - an old story. It has never been replicated and is in question.

Although Walford discusses it, he says he will still eat soy in moderation

(as will I).

AFA the other site about soy, " if you read it on the web, it must be true,

right " ?

My apologies. I should have checked the archives, but today is very

busy for me.

I never made any claim about its accuracy. Why do you doubt it?

Only because it doesn't look very scientific.

I've read this site a few times, and it has tens, if not hundreds, of

links to scientific studies and official bodies.

But I agree with you on looks, the guy is very immature in his

presentation.

Also, in 1998 I heard Dr say that whenever we could switch from meat to a soy product we would be better off (cancerwise). Cancer is a lot scarier to me then dementia. Just my take.

Do we know how much heredity plays in each? The odds are like cancer is number 2. Dementia at old age is almost a given if I get there (80?). In any case, the case for using some soy seems to me pretty good, daidzein, genestein, etc. There are literally billions of people eating soy, if that means anything. I don't eat that much, but I think that the type of fat has more to do with old age dementia than anything else. Just my take.

There are too many hits to evaluate now. No medical texts for soy and dementia that I have access to.

Neurology Volume 62 • Number 2 • January 27, 2004Dietary intake of fatty acids and fish in relation to cognitive performance at middle age.

This population-based study among middle-aged men and women showed that dietary cholesterol and to a lesser extent saturated fatty acid intake were associated with an increased risk of impaired cognitive function, whereas fatty fish and EPA and DHA consumption were associated with a decreased risk of cognitive impairment. These associations were independent of differences in age, sex, education, smoking, total energy intake, and cardiovascular risk factors. MUFA, total PUFA, linoleic acid, α-linolenic acid, and total fat intakes were not clearly related to cognitive function.

Conclusions:

Fatty fish and marine omega-3 PUFA consumption was associated with a reduced risk and intake of cholesterol and saturated fat with an increased risk of impaired cognitive function in this middle-aged population.

Clinics in Geriatric MedicineVolume 19 • Number 4 • November 2003Alzheimer disease and other dementias

Dementias are a group of illnesses associated with old age but that are not a normal part of aging.

Read this last study and if you have a good study on soy related tell me.

The subject is to broad to suggest an avoidance policy for me at least, for all the types.

As for scared, I've already told my daughter to shove my wheelchair off the dock if I get it. If I don't tell her mot to. I'm more concerned about stoke (number 3) actually.

Regards.

JW: Soy of course is eaten in Okinawa where the incidence of any of these

diseases (dementia, cancer) is much lower than anywhere in the world.

The A/D's in my family were all thin people who ate pretty abstemiously, smoked in younger years and drank little throughout their life. They all worked like demoniacs throughout their lives until their later years. Lot's of stress. I have no obesity on my paternal side of the family that has all the A/D issues. Another interesting thing....a complete lack of a spiritual component in their lives.

Of course also, the generalized word "soy" can mean a lot of diff foods. like tofu,fried tofu, miso, soy milk, soy beans, fried soy beans, soy protein isolate, so I'd like to know if they considered that in the studies. I know they don't eat it raw. I've seen them (Orientals) on TV eating deep fried lumps of tofu, I think. How smart is that? I think I 'd rather have a french fry.

But what I've read so far is not near conclusive about dementia. But, I'd have to vote for excess dietary fat being a worse cause then soy. Funny thing - the AD's I know/have known are thin people.

Another thing that struck me was that dementias (there are several causes) take a while to grow/acquire.

The significance of environmental factors in the etiology of Alzheimer's

disease.

Grant WB, A, Itzhaki RF, Savory J.

12 Sir Francis Wyatt Place, Newport News, VA 23606-3660, USA.

wbgrant@...

The proposition that environmental agents, such as diet, aluminum, and

viruses, are as important as genetic factors in the etiology of Alzheimer's

disease (AD) was advanced by the authors at the Challenging Views of

Alzheimer's Disease meeting held in Cincinnati on July 28 and 29, 2001.

Diet, dietary fat, and to a lesser extent, total energy (caloric intake),

were found to be significant risk factors for the development of AD in a

dozen countries, while fish consumption was found to be a significant risk

reduction factor. An acid-forming diet, such as one high in dietary fat or

total energy, can lead to increased serum and brain concentrations of

aluminum and transition metal ions, which are implicated in oxidative stress

potentially leading to the neurological damage characteristic of AD. Many of

the risk factors for AD, such as cholesterol and fat, and risk reduction

factors, such as whole grain cereals and vegetables, are shared with

ischemic heart disease. Aluminum may cause neurological damage and a number

of studies have linked aluminum to an increased risk for developing AD. The

evidence for viral agents playing a role in AD is the strong association

between the presence of HSV1 in brain and carriage of an apoE-epsilon4

allele in the case of AD patients but not of controls; statistical analysis

shows the association is causal. Diet, aluminum, and viral infections may

increase the prevalence of AD by eliciting inflammation, which may cause the

neurological damage that results in AD.
