Soybean in the world today is mostly GMO and comes mainly from the United States, Argentina and Brazil. It is notably this soy that supplies European livestock. According to a 2007-2008 report on total soybean production worldwide, soybean is 91% soybean GM in the United States, 98% in Argentina and 64% in Brazil. It has of course increased since.
The protein myth!Here is some information about tofu
In 120g of tofu, there are 9.4g of protein, 5g of fat, 2.9g of carbohydrates, 154mg of calcium and traces of niacin, riboflavin and thianine. In these same 120g, there are only 86 calories and there are all the essential amino acids necessary for a good nutritional balance.
This is because it contains trypsin inhibitors that prevent proper digestion of proteins and fatigue the pancreas. Even if you do not eat tofu, you can still eat it despite yourself.
Many processed products that you find in stores, as well as meat, contain soy derivatives. Because the animals were mostly fed with soy (and sometimes even with other things like animal carcasses) – Only organic meat is not fed this way. There are high estrogen levels among junk food eaters, big eaters of hamburgers.
Same for the myth that tells us that soy can help menopausal women .
The very serious British medical magazine “The Lancet” reported in 1997 a study that would prove that the mere fact of drinking two glasses of soy milk a day was enough to disrupt the menstrual cycles of women.
Isoflavones can prevent ovulation, promote the appearance of cancerous cells and hyper-thyroidism, the first symptoms of which may be lethargy.
Know nevertheless that according to Dr. Josèphe Mercola, eating unfermented soy entails a considerable series of serious consequences.
Among them :
- Thyroid cancer;
- Deficiencies of the pancreas;
- Deficiency of vitamin D and calcium (which causes osteoporosis, a reduction in the bioavailability of iron and zinc useful for brain health),
- A decrease or blockage of iron metabolism;
- Memory problems;
- Amino acid deficiencies;
- An increase in the rate of diabetes;
- Serious neurological and emotional problems ranging from bad mood to chronic or permanent depression;
- For some people, more mucus (stuffy nose and cat in the throat);
- Fatigue the immune system.
The only products that seem safe are fermented soybeans: miso, tempeh, natto and tamari; for little, of course, that they are BIO guaranteed without GMOs. Fermentation destroys trypsin inhibitors.
I’m not telling you to eat more, but to restrict your consumption or consume it reasonably.
For women : 2 drinks (meals and drinks) of soybeans per week
Once a week for by-products.
For men: 3 drinks (meals, beverage and by-products) per week.
But where to get my protein source?
Here is an info on the ANSES website (formerly Afssa); food and environment agency, on the subject:
It’s still a trifle of 440 pages! but at least everything is said on the subject!
Well obviously it dates from 2005 …. Like what the subject is already old!
Here is a summary :
Recommendations concerning adults in particular
The consumption of isoflavones does not present a risk when it is limited to 1 mg / kg / day in adults.
It is necessary to avoid accumulating sources of phyto-estrogens: for example foods derived from soy and food supplements, or food supplements composed of several types of phytoestrogens (isoflavones, coumestans …) especially if the total intakes of phytoestrogens do not are not specified.
Soy foods, such as tonyu, tofu, can be consumed without excess by adults as they reduce the intake of saturated animal fats, and as part of a balanced and diversified diet.
Vascular tonicity, the decrease of which often accompanies an increase in cardiovascular risk, is improved by isoflavones, at doses of 45 to 55 mg / day of genistein. Higher doses have not been shown to be safe.
The interaction of phytoestrogens with the synthesis of thyroid hormones imposes the exclusion of their consumption in any form whatsoever by treated or untreated hypothyroid subjects.
Although no allergy phenomenon has so far been reported with dietary supplements based on soy isoflavones, the variety of methods for obtaining these extracts should encourage people who are notoriously sensitive to soy protein to caution regarding these preparations.
Recommendations concerning more particularly pregnant women, infants and young children
Given the current state of knowledge and uncertainties regarding the long-term effects of high doses of isoflavones ingested by infants over a prolonged period of time, soy protein preparations should not be given to children under 3 years of age if those These are not reduced in isoflavones content. Due to their composition, tonyus (soya juice) is contraindicated for feeding infants and young children (from birth to three years).
Animal studies show that early stages of sexual organ development (during pregnancy and lactation) are particularly sensitive to exposure to phytoestrogens. Morphological abnormalities that can lead to a decrease in fertility but also a greater sensitivity to carcinogens are observed. An important precaution therefore appears to be to avoid in pregnant and nursing women a high consumption of isoflavones, especially in the form of food supplements. Similarly, consumption of soy products in infants (soy protein-based formulas) and infants (tonyus, soy yogurts) should be avoided.
Consumption of soy protein preparations should, in the case of infants and pregnant women, be less than 1 mg / L of reconstituted preparation (in aglycone equivalents46, ie approximately 0.15 mg / kg of body weight).
Recommendations concerning professionals in particular
In the current state of our knowledge, while awaiting controlled intervention studies, no relevant human study authorizes claims to prevent the degradation of cognitive functions in women with soy derivatives or isoflavone supplements.
The labeling of any soy protein diet intended for infants and young children must specify the phyto-estrogen content, expressed in aglycone equivalent, particularly on soy foods and food supplements. This means a dose control by the manufacturers at each production with a new lot of soy.
Consumers of soy products should be aware that these products contain isoflavones. The isoflavone composition of these supplements should be clearly indicated. The phrase “Talk to your doctor” should alert consumers to possible contraindications.
There are also interactions with other hormonal therapies (eg, tamoxifen) that may exacerbate or neutralize these treatments. The consumption of phytoestrogens should be avoided in these cases.
