Is there such a thing as a healthy breakfast cereal???

The studies prove enough to me that I don't think pre-menopausal women should be using soy. Due to today's poor food qualities and environmental toxins, many women, and some men for that matter, are estrogen dominant. The last thing an estrogen dominant person needs is soy and even at the slightest amount, it's a risk for someone in this situation. Now take a women on birth control.........do you really think adding in a substance that possibly increases estrogen is a good thing?

what studies are you looking at in pre-menopausal women?

again, what is the dosage that they are taking. Not that I am disagreeing with. Like I said, I don't think it is great. But, the research is really looking at upper limit dosages of soy.

The birth control issue i will just throw out the window because i don't think normal healthy people should be fucking with their horomones. I agree with you.

INTRODUCTION

It has long been recognized that phytoestrogens exert hormonal effects in cell culture systems and animals, but effects in humans have not been studied until quite recently. The primary hypothesis of most researchers has been that phytoestrogens lower estrogen levels and action in the high estrogen milieu of premenopausal women and act as estrogen agonists in the low estrogen milieu of postmenopausal women. It has been proposed further that antiestrogenic effects of soy isoflavone consumption may lower breast cancer risk in premenopausal women, whereas estrogenic effects may benefit the cardiovascular system, bone and vasomotor systems in peri- and postmenopausal women. Thus, hormonal effects might explain epidemiologic observations of lowered risk of chronic diseases and menopausal symptoms in populations that consume soy.

Despite the growing body of data, effects of soy consumption on endogenous plasma hormones have been inconsistent, probably as a result of methodological differences in subject characteristics, study design and length, determination of menstrual cycle parameters, and isoflavone form and dose. Most reported studies have used randomized crossover or parallel-arm designs, although some studies have had no true control group or diet period. Soy has been provided as isolated soy protein (ISP), soy milk, textured vegetable protein (TVP), soy flour or soy foods; isoflavones have been consumed at levels of 7???200 mg/d, and the lengths of the diet periods have ranged from 2 wk to 6 mo.

The major effects in premenopausal women consuming 45???200 mg/d of isoflavones in ISP, soymilk or TVP include decreased midcycle luteinizing hormone and follicle-stimulating hormone concentrations (Cassidy et al. 1994Citation and 1995Citation , Duncan et al. 1999aCitation ); increased menstrual cycle length (Lu et al. 1996Citation ); and decreased urinary estrogens, with a preferential decrease in proposed genotoxic estrogen metabolites (Xu et al. 1998Citation ). Increased menstrual cycle length and decreased urinary estrogen excretion may suggest reduced exposure to estrogen, and both have been associated with lowered risk of breast cancer. On the other hand, soy consumption has been observed to both increase (Petrakis et al. 1996Citation ) and decrease (Lu et al. 1996Citation , Nagata et al. 1998Citation ) plasma estrogen concentrations; one study reported increased nipple aspirate volume (Petrakis et al. 1996Citation ), suggesting estrogenic effects on the breast. Other observations include no effects on endometrial biopsy results (Duncan et al. 1999aCitation ) or plasma sex hormone???binding globulin concentrations (Cassidy et al. 1994Citation and 1995Citation , Duncan et al. 1999aCitation , Nagata et al. 1998Citation , Petrakis et al. 1996Citation ). These effects appear to be due at least in part to the soy isoflavones (Duncan et al. 1999aCitation ).

Few hormonal effects have been reported in postmenopausal women consuming soy isoflavones. The major effects reported in postmenopausal women consuming 34???165 mg/d of isoflavones in ISP, soy flour or soy foods include increased sex hormone???binding globulin (Brzezinski et al. 1997Citation , Duncan et al. 1999bCitation ), a modest decrease in the frequency (Murkies et al. 1995Citation , Albertazzi et al. 1998Citation ) and severity (Brzezinski et al. 1997Citation , Washburn et al. 1999Citation ) of hot flushes and vaginal dryness, and a slight increase in vaginal cell maturation (Baird et al. 1995Citation , Wilcox et al. 1990Citation ). One study showed decreased estrogens and no effects on endometrial biopsy results (Duncan et al. 1999bCitation ). These results suggest that soy consumption exerts modest estrogenic effects, likely as a result of the presence of soy isoflavones.

Thus, soy consumption appears to exert modest hormonal effects in both pre- and postmenopausal women. The effects are generally in the direction of providing health benefits, although they are quite small and of uncertain clinical significance. Further research must be performed to clarify the magnitude and significance of the hormonal effects of soy consumption, and, if effects are seen, to establish whether the responsible components are the isoflavones or some other soy constituent.

The only bread I've seen in the freezers locally is rice bread. Rye Bread is something like £3 for eight slices

How much does ezekiel bread cost you guys in the US/Canada etc? I've never seen it in the UK, only healthy food stores sell small 'blocks' of rye bread and thats quite costly.

Is there anything I can use instead? is Wholemeal/Granary ok or is nearly as bad as white bread? Thought white bread is ok post workout isnt it? as its a fast digesting carb.
 
Thus, consumption of soy containing 32???200 mg/d of isoflavones seems to increase menstrual cycle length and the ratios of 2- to 16{alpha}-(OH) and 2- to 4-(OH) estrogens and to decrease plasma concentrations of estradiol, progesterone, midcycle gonadotropins and SHBG as well as urinary estrogens. Some but not all of these effects go in the direction of cancer prevention. Studies suggest that both the isoflavones (5Citation ,19Citation ) and soy protein (20Citation ) may be responsible for these effects. At the same time, isoflavones do not seem to affect the endometrium (5Citation ), although there is some evidence for mild stimulation of breast cells by soy (21Citation ,22Citation ).
This reeks estrogen dominance right there. Why would anyone want to fuck with that. So many women have too low progesterone already! When you have decreased progesterone you have increase higher estrogen. Low progesterone can cause PCOS, amenorrhea, dysmenorrhea, fertility issues........the list goes on.

Low progesterone is not something any women should deal with. Here are a studies on premenopausal women and all them show these effects.
It can also lower T3 levels as well, as shown in the studies.

which study are you quoting up there?

one of the studies you have there is showing no significant effects. the other one is again using a very high dosage (something like 69g/day).
 
The first study which used 32g - 100g.

They all showed some decreased of progesterone and or T3.

Also the study said 60g but only provided 45g of soy isoflavones. Just because it says 60G doesn't mean it's 60G of soy isoflavones.
 
yea, that is a literature review...again, it is hard to take information from it becasue it is comparing a bunch of shit that is simliar but not the same. Also, because it is a review, it doesn't have an inclusion criteria for which studies they are looking at.

are the effects because of the soy? or because of the isoflavones?

there are still a lot of questions to be asked.

I don't think that soy is all that great. I think there is better shit to eat.

From the colclusion section of that research review:
Although these effects are generally in a beneficial direction, their clinical significance is yet to be established.

Future studies should focus on elucidating the responsible components and the optimal forms and doses as well as the dietary, environmental and genetic factors that influence particular subgroups to respond to soy.
 
I don't care what the studies show for amounts. If something has ill effects it shouldn't be used at all. To me, that's like saying 1 cigarette a day is fine. :shrug:

From what my ND told me, is that it's the isoflavones. Some of this is anecdotal evidence but, to me, still shows enough negative to stay away from it.

That makes no sense at all.

That is how statistical significance works.....everything we do has impact on our overall health. We take the good with the bad. If eating steak is good, but 1 out of 50 people that eat it die, then the statistical significance is small. People will eat steak and that is the risk they take (unless their name is mercola). If while eating steak 45/50 people die, then the statisical significance is greater....chances are most people wont be eating much steak.

Driking alcohol causes changes to the body....yet people do it.....in moderation...that is the key. just like anything, to much of one thing is never good.

No study has ever been developed showing that vitamins are abosibultly necessary to our diet. In fact, researchers would tell you that a healthy/well-balance diet does not need to be supplemented with vitamins as the individual would be getting their needed amounts of nutrients. But, we know there are benefits of taking certain vitamins. Statistical evidence shows that. So we take our vitamins.
 
Yeah I know what you mean, but after all the shit I've had to deal with and the estrogen dominance etc...to me, it's that bad. The last thing anyone needs with pre-existing estrogen dominance is to make it worse :shrug:

Some people it can have pronoun effects and other it will cause no problems at all. Everyone is different but those at risk, shouldn't chance it.
 
From what my ND told me, is that it's the isoflavones. Some of this is anecdotal evidence but, to me, still shows enough negative to stay away from it.

that's fine.

you can formulate opinions on conjecture. people do it all the time. look at the diet books that are written each year. Some of them grossly over-simplify the human diet and the author reports on what they believe to be true.

I agree with your ND. I don't feel that soy is a great overall protein. I think there are some negative impacts and the research shows that (although it is in higher doses than I would consume daily....so, it may apply more to those that eat soy as their only protein or those that eat high amounts of soy).

Still though, as the research says, more research is needed, to really formulate evidenced based prescriptions of soy protein.

Until then, I agree with your ND.....even if it is my own conjecture.
 
Yeah I know what you mean, but after all the shit I've had to deal with and the estrogen dominance etc...to me, it's that bad. The last thing anyone needs with pre-existing estrogen dominance is to make it worse :shrug:

I understand what you are saying.

But not everyone will have the same hormonal problems as you. Not everyone will have the same metabolism as you. You have to take things in stride, as they come, when working with people.

I can't take all my clients and have them back squat because I back squat....it would be insanity.

I can't have some of my clients eat a diet that is similiar to mine (higher in carbs) because they don't metabolism CHO as well as I do and they don't have the same metabolism as me.

One of the hardest things to do is seperate yourself from those you are working with....does that make sense?
 
Some people it can have pronoun effects and other it will cause no problems at all. Everyone is different but those at risk, shouldn't chance it.

agree 100%
 
Yeah, I agree, no doubt more research is needed. Look how many products and medications out there that they claimed safe and then overtime the negative effects showed face. Kinda scary with how much trust we put into the people making these statements. :shake:

Yup, makes complete sense. It's your responsibility as a professional to be subjective and open to all things. My career is not in this field so most research I do is mainly for myself. Most of my advice is based off that research as well as my own personal experiences. As I said in the beginning of all of this to dontstop - it may cause problems as she ages.
 
Yeah, I agree, no doubt more research is needed. Look how many products and medications out there that they claimed safe and then overtime the negative effects showed face. Kinda scary with how much trust we put into the people making these statements. :shake:

sometimes it is hard for them to predict what is going to happen.

also, changes in metabolism overtime as well as environmental changes, make things very hard to predict.


anyway.....

the reason i took such a long road to getting to the point that I agree was to just show everyone how critical you have to be when you read research and develop evidenced based practice (be it in training, nutrition, physical therapy). Sometimes, we browse an abstract and we take it as truth....again, none of this is truth. It proves nothing. It suggest statistical evidence. Much like the products claimed to be safe (at first they were shown to be helpful) and then after time are shown to be dangerous.....much like eggs would give you a heart attack if you ate more than 2 a week, like they did back in the 70's and 80's...only to find out how healthy they are for you.

If you are going to read research and analyze the statistics, you have to be critical of what you are reading. Don't jsut go fishing for things that support your beliefs and don't take what you read to be an absolute....it isn't. It just means at that time, this is what was found.

Some smoke ciggies all their life with no problems too ... others are not as lucky.

Point is we are trying to learn a better way to eat and live longer. Soy is not good for that goal with the increased estrogen.

Too each his/her own though.
Agreed. It has been mentioned that some "bad things" are okay in moderation, however, even though I agree (because life should be enjoyed), these things may (and likely) have negative affects on the body which we do not immediately realize. This reminds me of a conversation I had with a friend who is aspiring to become a professional kickboxer. He used to smoke weed on and off, but quit once he noticed the affects of it on his body after reaching the level of training/athleticism that he has. I don't think you can ever be too nitpicky on this forum. It is a health/bodybuilding forum after all; I thought that was the point. Some great information posted so far. I have been wanting to learn more about the soy protein debate.
 
Milk consumption in childhood is associated with the greatest peak adult bone density, but milk consumption in adulthood is associated with increased prevalence of fractures, and with accelerated bone demineralization.

Dynamic Chiropractic Jan 1 said:
While dairy promotions also include praise for the protein of milk as well, this protein may be more of a problem in osteoporosis than calcium could be a solution. The animal proteins of meat and dairy products cause calcium loss.9 The level of calcium needed in the diet depends greatly on the animal protein intake.10 For many of the high animal protein diets of Americans, it may not be possible to consume enough calcium in the diet to compensate for the amount lost to these high-acid proteins.11 For this reason, Americans have among the highest osteoporosis rates in the world, while their dairy intake is also among the highest. Doubled animal protein causes 50 percent more calcium loss. Yet, when a high protein intake is soy-based, a positive calcium balance can be maintained with only 450 mg of calcium per day.12

The chief concern over bone density is that it gradually reduces with maturity. At a certain point of bone loss, the term osteoporosis is used. This is a level where low-trauma bone fractures become more frequent. Spinal fractures are a problem, as are hip and arm fractures, which are easier to measure for research purposes. The highest level of bone density attained in young adulthood correlates with bone density maintained in later decades. What is not entirely understood is how much impact dietary factors have on these events. Some studies suggest that childhood calcium intake before puberty may have some slight positive effect. At the same time that diabetes, cancer, and other concerns may limit the amount of dairy that should be given to a child, it also appears that bone protection is no reason to promote dairy consumption beyond childhood.

In 1986 a Harvard researcher produced a graph that demonstrated a nearly direct relationship between calcium intake and hip fractures - the more calcium, the more fractures.13,14



A 1987 study of 106 adult women suggested that calcium intake between 500 and 1,400 mg per day led to no difference in bone mineral densities.15

A larger Italian study found that in women who consumed between 440 and 1,025 mg of calcium per day, a slightly increased number of hip fractures occurred with higher milk intakes.16

A recent study of 78,000 nurses found that women who drank more than one glass of milk per day had a 45-percent greater chance of hip fractures compared to those who drank far less.17 Those who took in the same amount of calcium from nondairy sources saw no such increase, nor a decrease in fractures. Since many studies are performed on women only - they do suffer more osteoporosis - Harvard researchers decided to look at men. They found that those who drank three or more glasses of milk per day, compared to one or less per week, had very slightly fewer hip fractures, but these were balanced by slightly more arm fractures.18 The highest calcium intakes from food and supplements together produced an increase in fractures overall.

The rate of hip fractures in the U.S. for people of many races and ethnic origins is exactly inverse to their rates of lactose intolerance. In other words, those who are likely avoiding milk as adults have the fewest fractures. Non-Hispanic white women have 139 fractures per 100,000 people; Mexican-Americans have 67 per 100,000; and African-Americans average 55 per 100,000.19 The indigenous peoples of South Africa have not traditionally been dairy consumers. Their consumption is still very low, although formula is making great inroads. Those of osteoporosis age today however would not have been raised on formula. Typically, South Africans consume only 200 mg of calcium per day, but their rate of fractures is extremely low - fewer than seven per 100,000 people per year.20 Compare this to their dairy-exposed American counterparts. The milk-drinking (and higher calcium intake) populations around the world are the ones who have osteoporosis as a major problem.21 These rates are increasing in typically low fracture areas around the world as these regions adopt Western practices.

In Japan, as in many other non-Caucasian populations, dairy intake has traditionally been minimal and calcium intakes have been low - and hip fracture rates are low, but have been growing recently,22 as is the portion of adults who were raised on dairy. While industrialization also brings reduced physical exercise, there is a much more consistent common denominator seen in the timing and geographic regions of these bone problems - cow's milk. While we feel our nutrition is superior today over centuries past, archeological research has shown that Caucasian post-menopausal bone loss in the 18th and 19th centuries was less than that seen today.23 Clearly, high calcium intake, and certainly high dairy intake, are not the prevention for osteoporosis.
 
I was a cereal fanatic, to the point where my mother would buy abnormally large bowls just for me to use.

It wouldn't be outrageous for me to eat an entire box of Trix or Cinnamon Toast Crunch in a sitting. Of course I was using Skim Milk, so my dumbass mind thought I was eating something really healthy.
