Re: how do you eat your broccoli.. raw?

[Guest guest]

Hi Bill and All, 8 minutes of full-power microwaving may be more cooking than steaming for 30 minutes or less, or blanchiing in the microwave. http://cebp.aacrjournals.org/cgi/reprint/13/1/125 http://cebp.aacrjournals.org/cgi/content/full/13/1/125 Cancer Epidemiol Biomarkers Prev. 2004 Jan;13(1):125-31.Hydrolysis of glucosinolates to isothiocyanates after ingestion of raw or microwaved cabbage by human volunteers.Rouzaud G, Young SA, Duncan AJ. Cabbage contains the glucosinolate sinigrin, which is hydrolyzed by myrosinase to allyl isothiocyanate. Isothiocyanates are thought to inhibit the development of cancer

cells by a number of mechanisms. The effect of cooking cabbage on isothiocyanate production from glucosinolates during and after their ingestion was examined in human subjects. Each of 12 healthy human volunteers consumed three meals, at 48-h intervals, containing either raw cabbage, cooked cabbage, or mustard according to a cross-over design. At each meal, watercress juice, which is rich in phenethyl isothiocyanate, was also consumed to allow individual and temporal variation in postabsorptive isothiocyanate recovery to be measured. Volunteers recorded the time and volume of each urination for 24 h after each meal. Samples of each urination were analyzed for N-acetyl cysteine conjugates of isothiocyanates as a measure of entry of isothiocyanates into the peripheral circulation. Excretion of isothiocyanates was rapid and substantial after ingestion of mustard, a source of preformed allyl isothiocyanate. After raw cabbage consumption, allyl isothiocyanate was again rapidly

excreted, although to a lesser extent than when mustard was consumed. On the cooked cabbage treatment, excretion of allyl isothiocyanate was considerably less than for raw cabbage, and the excretion was delayed. The results indicate that isothiocyanate production is more extensive after consumption of raw vegetables but that isothiocyanates still arise, albeit to a lesser degree, when cooked vegetables are consumed. The lag in excretion on the cooked cabbage treatment suggests that the colon microflora catalyze glucosinolate hydrolysis in this case.

Yes, love them too, and usually raw. But regarding *vinegar*, is it

advisable to consume ample amounts of it and other very acidic foods?

I know that some practioners of CRON, such as Ray Kurzweil, try to

keep their diet quite alkaline, but I am not so certain that this has

been fully justified scientifically.

It is my understanding the body takes great care to maintain a very

specific and limited PH value, any deviation from this limited PH may

result in death. I doubt food eaten can influence this. Is this true,

does anyone know? Jeff, can you help here?

Hey Bill

I think you are mostly right. But food can influence

the Potential Net Renal Acid Load, which may have some

metabolic implications (i.e., calcium loss).

While PRAL can be measured it can also be estimated by

dietary intake and somewhat by urine PH.

However, when you look at the effect of foods on PRAL,

you will see that fruits and veggies are the best, and

processed refined foods, dairy and animal protein are

the worst, and fat about neutral. I dont think anyone

following a healthy diet , like CRON, would need to

worry about it unless they were prone to a specific

medical issue that may be effected by it (ie, calcium

stones).

Search pubmed, or google for the topic and you will

see quite a few references on it.

Regards

Jeff

PS I have a copy of a recent article on it from an

alternative medical journal if anyone wants to see it.

I am not Jeff, but I do know a lot about homeostasis, which is essentially how the body adapts to environmental changes in order to maintain a steady state. A good (non-food) example is how the respiratory rate increases at high altitudes, so that cellular oxygenation will be maintained. Being an anesthetist, I see this frequently during anesthesia and surgery and have found over many years that the less we alter the physiology, thereby letting the body maintain homeostasis, the better it is.That is why I am not a believer in much of the "stuff" out there about acid/alkaline, blood type, water fasts, etc. The body takes care of itself. Of course I know that obesity, the body holding on to excess fat cells and why some people have more of a problem with food than others is not clearly understood. Right now I am trying to carefully note my responses to certain types of food, drink and eating patterns. The major thing I have determined for myself is that eating small amounts and in a five hour window seems to be working for me to lose weight and especially inches.Most of us are looking for some good hard science on these topics. I personally place little credence in any physician, weight loss guru, celebrity or fitness monkey who offers regurgitated opinions on a complicated problem/solution without good supporting science.
