Whey -vs- Soy

Discussion in 'Strength & Conditioning' started by codivecop, Feb 6, 2005.

  1. Has anybody heard pros/cons to either? I had a guy tell me that he heard........ Soy is good for women, but it has side-effects in men.

    Now knowing that the internet is full of "stuff", I still couldn't find any crediable research that says men should avoid Soy. As a matter of fact, I found some taht suggests it helps prevent some cancers.....

    Anything one way or the other---- CREDIABLE PLEASE!!!!!!!!;e

    Myth: A soy burger is healthier than a beef burger
    Here's the problem: Soy, in all its forms, contains phytoestrogens--that is, plant estrogens. And while having some of the female hormone in our bodies is okay, and even normal, having high amounts of the plant version isn't. In fact, Australian researchers found that men who consumed a soy-rich diet had significantly lower testosterone levels than beef eaters. And as for red meat's artery-clogging reputation, a study published in the Journal of the American College of Nutrition showed that eating lean beef can help to lower LDL cholesterol levels while increasing HDL levels.

    I would stick with the whey
  7. Thanks to all so far.

    Here is the reason for the question: The protein shakes & bars that I use (because they TASTE GOOD) are a mix of Whey & Soy Proteins.

    I am not planning on using WHEY or SOY solo, but other than the bars & shakes I will probably be adding Whey powder.

    As far as the link above, I could not get it to work. Don't know if it is because of the weekend, bandwidth issues or what..... But thanks for trying and I will try again this week.

    Any other articles would be appreciated. ;f

    Soy has too many negative properties for me to even start.

    Stick with whey.
  9. Not to sound like me High School English teacher, but:

    Cite your sources, please. :)

    Personal experiance is great, but I am looking for documented research that says Soy is not good for men.

    This is from the Weston A. Price Foundation. I personally won't knowingly touch soy protein, as there is so much stuff that is better out there (Caseinate, Whey in small amounts, Egg Protein, real food - go fig)

    I don't bodybuild, I am a competitive strongman in the North American Strongman Society. Even though I am 350+lbs, I avoid eating crap, and soy is crap.

    Myths & Truths About Soy

    Myth: Use of soy as a food dates back many thousands of years.

    Truth: Soy was first used as a food during the late Chou dynasty (1134-246 BC), only after the Chinese learned to ferment soy beans to make foods like tempeh, natto and tamari.

    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, 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 to neutralize toxins in soybeans, and are processed in a way that denatures proteins and increases levels of carcinogens.

    Myth: Soy foods provide complete protein.

    Truth: Like all legumes, 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 protein digestion and affect pancreatic function. In test animals, diets high in trypsin inhibitors led to stunted 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.

    Truth: Soy foods can cause deficiencies in calcium and vitamin D, both needed for healthy bones. Calcium from bone broths and vitamin D from seafood, lard 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 with symptoms of lethargy, constipation, weight gain and fatigue.

    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: Phytoestrogens in soy foods can enhance mental ability.

    Truth: A recent study found that women with the highest levels of estrogen in their blood had the lowest levels of cognitive function; In Japanese Americans tofu consumption in mid-life is associated with the occurrence of Alzheimer's disease in later life.

    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 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 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.

    Myth: Soy beans are good for developing nations.

    Truth: In third world countries, soybeans replace traditional crops and transfer the value-added of processing from the local population to multinational corporations.
