Is Soy Bad?

Soy has become so popular because of the industry advertising. It started me off as a believer! There was considerable research done in 1966 about the harmful substances within the soybeans. And now, it’s claimed to be the “miracle” food.

Production of soybeans in the U.S. is 40 times more now than it was starting in the 20th century. First it’s made for animal feed and then manufactured into soy oil, vegetable oil, margarine, and shortening.

Why has the soy industry concentrated on finding alternative uses and new markets for soybeans? Because it’s cheap and very profitable. It’s disguised in everything from hamburgers, hot dogs, baby formula, flour, and much more. It’s often marketed as low-fat, dairy free, or as a high protein meat substitute for vegetarians. The soy derivatives you need to look for are textured vegetable protein (TVP), partially hydrogenated soybean, soy protein isolate (SPI) hydrolyzed vegetable protein (HVP).

One of the dangerous substances in the soybean is phytic acid, also called phytates. These acids block the body of essential minerals like calcium, magnesium, iron and especially zinc. But, you never hear about that.

When you start to read labels very carefully you will be amazed at the soy contents in snack foods, fast foods, and pre-packaged frozen meals. It’s also in canned tuna! Why you need soy in tuna?

They say soy foods are a source of high-quality protein that provides health benefits that may help to prevent or treat certain chronic diseases. This is definitely not so for someone with a severe allergy to soy – like me. You may not be allergic to soy, but you could have a soy intolerance. Soy is bad so look for healthier alternatives.

Soy does not reverse child obesity and provide critical vitamins, minerals, fiber and protein. They claim soy foods contain less calories and fat grams making weight loss easier. Kid friendly foods like soymilk, frozen pizza, taco-style meat and chicken-style nuggets. Is soy bad? This doesn’t sound like a healthy diet to me.

Soy is bad because they are not filled with bone-building and heart-healthy soy protein, or reduce overall calories and fat grams. If this was true, I would not have gained weight with my active lifestyle. And what about women who are in their forties that start gaining weight? I believe it’s because of the all the soy products that they are consuming. And, they could possibly be developing thyroid disease and not know it. Don’t believe what you hear about women going through menopause. It didn’t reduce my “hot flashes”, lower my cholesterol, decrease my risk for heart disease, or osteoporosis. Is soy bad? It sure is! Soy nearly killed me! And I thought I was following a healthy diet.

When it comes to fad diets they claim soy foods help promote healthier eating habits with low carb diets. They say many soy foods are naturally low in fat and saturated fat, while being high in heart-healthy protein. The example they use is a soy veggie burger provides 12 grams of soy protein with 5 grams of fat, 1 gram of saturated fat and just 3 grams of net carbs. That soy veggie burger is what landed me in the hospital…my body said “enough all already!” It took four days in the intensive care unit for me to get the “wake-up” call.

Everyone know their own bodies. If you are not feeling like yourself lately, try to eliminate soy products – I bet you will start feeling like your old self again!

Is soy bad? Let your body be the judge… listen to it.

    In addition to all the products that you have named,

    soy might also be one of the ingredients in Tocopherols. Vitamin E comes from a variety of oils, and now soy oil is probably an ingredient as well because of it's low price. Tocopherols are listed on many products, including some Probiotics so it is always wise to call the manufacturer and ask.

    Keep up the great work, Dianne!

    I've read in the Journal of American Medicine Association ( that organic, fermented soy is incredibly beneficial, rather than the un-fermented soy that is in the majority of products we eat. They are correct, no?

    Andrea, you are correct. Fermented soy is fine.

    Thanks for your comment.

    I hear about phytates being an anti nutrient among the low carb community all the time. What I don’t hear is the fact that when you eat iron, zinc, copper, and these other minerals in excess~easy to do when eating animal foods~the phytates can actually block excesses from being absorbed that actually lead to oxidative damage. This is one of the components that have been found in actual studies done recently in Chicago, and in Europe that leads to a higher risk for cognitive decline and Alzheimer’s. Excesses & deficiencies of these minerals is not good. When getting them from plants, they are more naturally self-regulated by the body. Excesses are not absorbed as they are from animal sources. Phytonutrients incl. these ‘anti nutrients’ have health benefits that unfortunately the word smithing distorts, and causes people to fear these foods.

    I would really like to better understand what the etymology of your diseased state that landed you in the hospital was. What all else were you eating? What was stress in your life like at the time? There are hundreds of thousands of cases of E Coli and salmonella poisoning that occur annually that no one reports. These are born from animal foods, not plants. Those veggie burgers often have egg whites in them. Not saying that was the case for you, but the symptoms and conditions would be similar. I agree that soy is over used, as is typical of our food production and corporations that want to maximize profits. Eliminating isolated soy proteins is good advice, but passing around opinions cloaked as facts is irresponsible. There are plenty of studies supporting the health benefits of traditionally prepared soy foods, incl. soy milks. Consuming soy foods is by far a better alternative than whey, which is the byproduct of cows milk, loaded w/ real problems. Hormones, antibiotics, and lots of nasty stuff in milk, not to mention the incredible harm and cruelty from which it is produced.

      It’s very interesting…when I was a child my mother gave me Carnation instant breakfast and I broke out in a rash. She never gave it to me again. When I reached menopause, I read about the healthy benefits of soy protein, and tofu helps hot flashes, prevents osteoporosis, balances hormones, etc…Soy did not eliminate hot flashes. What it did do was created bloating, nausea and I gained 35 lbs. I complained to doctors for 8 years and they said there was nothing wrong with me and that it was normal.

      Asian countries only consume about 9 grams of fermented soy daily. Where here in the states it’s more like 35 grams that is also not fermented (toxins are left in) like it is in Asia. That’s why they have a lower risk of heart disease, cancer, and thyroid problems. But, studies have shown that when they move the the U.S. they have the same problems we do.

      Also, keep in mind that the studies you refer to are by scientists that are paid to give rave reviews. In my study I also read that scientists who disagreed had their labs shut down.

      After all this – I developed hypothyroidism which I do believe was caused by my consumption of soy.

    Just because soy has been consumed in parts of Asia, mostly China, Japan and to a lesser extent Korea, does not mean it is an ideal food for the rest of the world. Do any of you consider the fact that Chinese and Japanese can handle soy better than people who traditionaly never consumed soy in any form, such as Europeans, Africans or Native Americans, and even Asian cultures such Indians ? And modern soy is just garbage anyway.

    How many of you noticed huge improvements in your hair and skin after totally eliminating soy from your diet? Mine improved and became very healthy after cutting all soy out, and it does not surprise me, considering that soy is toxic to the thyroid and is an endocrine disrupter.
