Taimne valk: soja, sojavalk, sojajahu

Põhjus miks sojavalgus tundub olevat rohkem aminohappeid on tingitud sellest, et sojavalk on isolaat, st. kõrgema valgusisaldusega, vadak on kontsentraat, madalama valgusisaldusega.See ei tähenda, et sojavalk oleks parem, kuna temas on rohkem aminohappeid.Võrrelda kontsentraati ja isolaati on sama nagu võrrelda täismahla ja nektarit.Võrrelda tuleb sojaisolaati ja vadakuisolaati.Kvaliteetses vadakuisolaadis on samamoodi 80-90% valku ning vastavalt on ka aminohapete kogused võrreldavad.Ning sellisel juhul on vadaku aminohappeline profiil lihaskasvuks parem.

Sojas olevatest fütoöstrogeenidest ja aromaatsetest ühenditest ja nende kahjulikkusest on juba küllalt räägitud, siin ma rohkem ei peatuks, aga ma lisan veel, et sojaoa põllud on ühed kõige rohkem väetiste ja pestitsiididega mürgitatud põllud üldse.

Kui sa enda peal midagi uut proovida ei julge ja usud pimesi, et Otti, Imre, Mareki või kellegi teise treeningmeetodid töötavad ka sinu peal 100% siis oled sa tõesti loll.

Kas sa neljanda korruse aknast oled välja hüpanud? Usud teiste kogemust, et pole hea mõte? LOLL!

no siis kõik selge. probleemi pole.

Seda teemat on varem ka lahatud, kuid mitte kunagi eraldi teemas. Kogusin veidi informatsiooni ja otsustasin seda levitada. Vabandan, et tekst on inglise keelne. Olulisemad sõnad olen ära tõlkinud.

Myth: Asians consume large amounts of soy foods.

Truth: Average consumption of soy foods in Japan and China is 10 grams (about 2 teaspoons) per day. Asians consume soy foods in small amounts as a condiment (maitseainena), and not as a replacement for animal foods.

Myth: Modern soy foods confer the same health benefits as traditionally fermented soy foods.

Truth: Most modern soy foods are not fermented (kääritatud) to neutralize toxins in soybeans, and are processed in a way that denatures (muudab loomulikke omadusi) proteins and increases levels of carcinogens (kantserogeenid).

Myth: Soy foods provide complete protein.

Truth: Like all legumes (kaunviljad), soy beans are deficient in sulfur-containing amino acids methionine and cystine. In addition, modern processing denatures fragile lysine.

Myth: Fermented soy foods can provide vitamin B12 in vegetarian diets.

Truth: The compound that resembles vitamin B12 in soy cannot be used by the human body; in fact, soy foods cause the body to require more B12

Myth: Soy formula is safe for infants.

Truth: Soy foods contain trypsin inhibitors that inhibit (keelab) protein digestion and affect pancreatic function. In test animals, diets high in trypsin inhibitors led to stunted (piiratud) growth and pancreatic disorders. Soy foods increase the body’s requirement for vitamin D, needed for strong bones and normal growth. Phytic acid in soy foods results in reduced bioavailabilty of iron and zinc which are required for the health and development of the brain and nervous system. Soy also lacks cholesterol, likewise essential for the development of the brain and nervous system. Megadoses of phytoestrogens in soy formula have been implicated in the current trend toward increasingly premature sexual development in girls and delayed or retarded sexual development in boys.

Myth: Soy foods can prevent osteoporosis (luude hõrenemist).

Truth: Soy foods can cause deficiencies in calcium and vitamin D, both needed for healthy bones. Calcium from bone broths (puljong) and vitamin D from seafood, lard (rasv) and organ meats prevent osteoporosis in Asian countries—not soy foods.

Myth: Modern soy foods protect against many types of cancer.

Truth: A British government report concluded that there is little evidence that soy foods protect against breast cancer or any other forms of cancer. In fact, soy foods may result in an increased risk of cancer.

Myth: Soy foods protect against heart disease.

Truth: In some people, consumption of soy foods will lower cholesterol, but there is no evidence that lowering cholesterol improves one’s risk of having heart disease.

Myth: Soy estrogens (isoflavones) are good for you.

Truth: Soy isoflavones are phyto-endocrine disrupters. At dietary levels, they can prevent ovulation and stimulate the growth of cancer cells. Eating as little as 30 grams (about 4 tablespoons) of soy per day can result in hypothyroidism (peaks olema kilpnäärme alatalitus) with symptoms of lethargy (loidus), constipation (kõhukinnisus), weight gain and fatigue (väsimus).

Myth: Soy foods are safe and beneficial for women to use in their postmenopausal years.

Truth: Soy foods can stimulate the growth of estrogen-dependent tumors and cause thyroid problems. Low thyroid function is associated with difficulties in menopause.

Myth: Soy isoflavones and soy protein isolate have GRAS (Generally Recognized as Safe) status.

Truth: Archer Daniels Midland (ADM) recently withdrew its application to the FDA (Food and Drug Administration) for GRAS status for soy isoflavones following an outpouring of protest from the scientific community. The FDA never approved GRAS status for soy protein isolate because of concern regarding the presence of toxins and carcinogens in processed soy.

Myth: Soy foods are good for your sex life.

Truth: Numerous animal studies show that soy foods cause infertility (viljatus) in animals. Soy consumption enhances hair growth in middle-aged men, indicating lowered testosterone levels. Japanese housewives feed tofu to their husbands frequently when they want to reduce his virility.

Myth: Soy beans are good for the environment

Truth: Most soy beans grown in the US are genetically engineered to allow farmers to use large amounts of herbicides (taimemürk).

Fred Antson sojavalgust:

On väga palju teaduslikku tõendusmaterjali,et sojavalgu pidev tarbimine viib häireteni meeste ja laste endokriinnäärmete talitluses – testosterooni produktsioon saab häiritud.Ka naiste puhul on soja kasulikkus pandud viimasel ajal kahtluse alla.Põhjused,miks sojavalku ja sojaõli igale poole lisatakse,on puhtalt ärilised – majanduslikud:sojauba on tulus kasvatada,sest ta järele on tekitatud vajadus,haipides tohutult tema küsitavaid positiivseid omadusi (kolestroolivaba,rasvavaba) ja vaikides maha kahjulikud mõjud.Pealegi on enamus maailmas toodetud sojast geneetiliselt muundatud.

Puberteediealised poisid ja mehed – kui te harva mõnda sojatoodet tarbite,siis ei juhtu veel midagi,kuid parem on temast siiski eemale hoida,rääkimata regulaarsest tarbimisest.Ja lapsevanemad peaksid hoolega vaatama,et imikute toitesegud ei sisaldaks sojavalku,sest selle manustamine takistab väikelapse normaalset hormonaalset arengut!

Soja on keskmise imendumiskiirusega,kõige paremini sobivad hiliseks tarbimiseks aeglase toimega kaseiini- ja munavalgud.

The effects on the thyroid gland of soybeans administered experimentally in healthy subjects

To elucidate (välja selgitada) whether soybeans would suppress the thyroid function in healthy adults, we selected 37 subjects who had never had goiters (kilpnäärme paisumine) or serum antithyroid antibodies. They were given 30g of soybeans everyday and were divided into 3 groups subject to age and duration of soybean administration. In group 1, 20 subjects were given soybeans for 1 month. Groups 2 and 3 were composed of 7 younger subjects (mean 29 y.o.) and 10 elder subjects (mean 61 y.o.) respectively, and the subjects belonging to these groups received soybeans for 3 months. The Wilcoxon-test and t-test were used in the statistical analyses. In all groups, the various parameters of serum thyroid hormones remained unchanged by taking soybeans, however TSH (Thyroid-stimulating hormone) levels rose significantly although they stayed within normal ranges. The TSH response after TRH stimulation in group 3 revealed a more significant increase than that in group 2, although inorganic iodide levels were lowered during the administration of the soybeans. We have not obtained any significant correlation between serum inorganic iodide and TSH. Hypometabolic symptoms (malaise, constipation, sleepiness) and goiters appeared in half the subjects in groups 2 and 3 after taking soybeans for 3 months, but they disappeared 1 month after the cessation (lõpetamist) of soybean ingestion. These findings suggested that excessive soybean ingestion for a certain duration might suppress thyroid function and cause goiters in healthy people, especially elderly subjects.

Biological effects of a diet of soy protein rich in isoflavones on the menstrual cycle of premenopausal women

The influence of a diet containing soy protein on the hormonal status and regulation of the menstrual cycle was examined in six premenopausal women with regular ovulatory cycles. Soy protein (60 g containing 45 mg isoflavones) given daily for 1 mo significantly (P < 0.01) increased follicular phase length and/or delayed menstruation. Midcycle surges of luteinizing hormone and follicle-stimulating hormone were significantly suppressed during dietary intervention with soy protein. Plasma estradiol concentrations increased in the follicular phase and cholesterol concentrations decreased 9.6%. Similar responses occur with tamoxifen, an antiestrogen undergoing clinical trial as a prophylactic agent in women at high risk for breast cancer. These effects are presumed to be due to nonsteroidal estrogens of the isoflavone class, which behave as partial estrogen agonists/antagonists. The responses to soy protein are potentially beneficial with respect to risk factors for breast cancer and may in part explain the low incidence of breast cancer and its correlation with a high soy intake in Japanese and Chinese women.
