Soy - Good or Bad?

Soy is indeed a good source of nutrition, especially for the sake of keeping a heart-healthy diet.  Just 25 grams of soy per day may reduce the risk of heart disease by lowering your cholesterol.  Most soy foods are also low in saturated and trans fats, another reason why soy is good for your heart.  Recent research suggests that soy may also lower risk of prostate, colon and breast cancers as well as osteoporosis and other bone health problems, and alleviate hot flashes associated with menopause.

Consumers purchase soy because of the protein it provides.  You may have heard of people having soy burgers or soy milk.  Soy has what is called a "complete" protein file, which means, like animal proteins, it has all of the amino acids humans need in their diets except it doesn't have the fat that comes along with eating meat.  Vegetarians eat soy foods because the soy protein replaces the animal proteins that non-vegetarians intake.


Though soy definitely has a major positive effect on one's health, there is still some concern about consuming soy protein.  One concern is soy's effect on the thyroid gland.  Some research has shown that soy may have a negative effect on the thyroid gland, but further research and more evidence is needed to prove this.  Phytoestrogens, the cause of thyroid problems, are found in soy-based infant formulas, another source of apprehension.  Another concern is soy allergies.  People with a soy allergy can suffer everything from hives and diarrhea to breathing difficulties upon eating this food.  With all of this unease, anti-soy activists think soy is not as good as it is cracked up to be.  Keep in mind that all of these claims have not yet been proven completely true.

I personally think soy is great for your health.  Through my research, I found no clear evidence of negative side effects to health.  So to all of you vegans and vegetarians out there, keep doing what you do!  Soy is good for your heart and is chalk full of many other nutrients to keep your body healthy!

  1. I think soy, taken in moderation, is pretty good for you health too. :) I didn't know that 25 grams of soy per day helps reduce the risk of heart disease by lowering your cholesterol. Although, I did know it has many benefits for your body. When people were discussing the negative effects of soy on the body, do you think they were talking about the nonfermented kind, which was mentioned in Dmeach's blog?

  2. Wow nick great facts. I never knew that daily soy would lower my chance of having heart disease. After finishing my blog i was set on negative effects, but after reading around i dont think soy is that bad. I do think it depends on nonfermented or fermented though. Overall i think i have come to the final conclusion that soy may not be that bad, in moderation and by eating the right type. Good Blog NI!

  3. Nice job Nick. I also established in my blog that soy is not as bad as many people make it out to be. Soy is acually a very safe alternative to meat, but only when the right type is used.

  4. Great job Nick,
    From reading most people's blogs, it seems that soy has the potential to be either a good, healthy alternative to meat products if it's fermented (although too much is naturally a bad thing), or a bad, carcinogenic product that can cause you real problems. It's funny to think that the fermenting process for this bean can prove such opposing effects if it is either done or not done and people consume it!!

  5. Every single food on Earth has negative consequences if you eat it in excess. It's possible to even die of water intoxication (and it's happened before). That said, you're really not taking much of a health risk when you eat soy. But just as you would with every food on this planet, don't eat too much of it.

  6. To answer your question, Jaden, I do think the negative consequences were concerning the non-fermented soy. I've started to wonder: why wouldn't soy producers ferment all of their products?!

  7. Nice post nick. I think you pointed out (with facts) that soy is not so bad as some people make it seem. Like devin said when the right type is used, it is a great alternative. Soy is a good choice but must not be eaten without knowing the pros or cons. Nice work.

  8. Stupendous work Nick. First off, I was interested to learn about the complete protein file. I had never heard of that until now. I would like to look into what exactly a thyroid gland does, but I'm lazy and probably won't look into it haha. I liked that you covered positives and negatives but didn't make your post super long, like mine. I try to do that, but it doesn't seem to work well. As I mentioned on Erica's post, I have seen in my research both that soy reduces the chance for breast cancer and soy causes breast cancer. You and Erica must have had different resources. I wonder which is right? Don't really care though haha. Good job.

  9. Nick, I liked how you were very specific throughout your article. For example, instead of just saying that research has suggested that consuming soy daily may reduce the risk of heart disease and lower your cholesterol, you mentioned a number with it. I really like how you were specific in saying that 25 grams is the suggested daily amount, for this helps people to get just enough without "overdosing" as some may call it. I also found the thyroid gland information particularly interesting. One time after I had blood work done something regarding my thyroid count was messed up, and my doctor asked me if I consume soy. I found that to be the most random question, but now I see why it relates.

  10. Haha. That's kind of cool, Molly. We have just witnessed a real-life application with one of our very own classmates. Nice!
