I know… you are just DYING to know what soy protein isolate is and if you should be avoiding it. Let me start again, have you ever even seen that ingredient?
SOURCE (and a good article to read)
maybe you’re an avid nutrition label reader, or maybe you are like me 95% of the time and are just on Supermarket Sweep to prevent a toddler/baby meltdown in Kroger.
“Soy protein isolate is a dry powder food ingredient that has been separated or isolated from the other components of the soybean, making it 90 to 95 percent protein and nearly carbohydrate and fat-free.” SOURCE
Asian populations use large amounts of soy products. They also have the longest and healthiest lives in the world. Soy was even given the health claim that “25 grams of soy protein a day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.”
However, to make soy protein isolate, soybeans are chemically engineered to “isolate” their protein.
This process strips out all of the other nutrients the original bean contained. It’s pretty sad that 90+ percent of soybeans grown in the U.S. are genetically modified. So add a genetically modified soybean to that chemical process and you have soy protein isolate.
Nutritionists from Prevention agree that there are MANY benefits to QUALITY soy, but they recommend purchasing fermented soy sources- miso, tempeh, and natto because fermentation increases the digestibility of soy, adds good bacteria, and reduces the plant estrogen content in soy foods. SOURCE
One of the most controversial parts of soy are its isoflavones- antioxidants that mimic estrogen in the body. These can increase bone mineral density and decrease the frequency and severity of hot flashes. BUT (because there’s always a but), isoflavones have also been documented contributing to the risk of breast cancer.
Ay-ya-ya. Is anything good for you?!
MY TAKE- With all the research I’ve been doing, every single food has been linked to cause something. Again, you just can’t win.
Instead… eat everything in moderation. TRY eating a majority of your foods as close as you can to the way God put them on this earth. Want protein? Try beans, meat, greek yogurt, nuts, etc. Get it from REAL food. But if you aren’t getting the daily recommended amount (46-56g for the average adult) try pea or hemp protein- plant based ones. My favorite protein powder
I am not an advocate of eliminating anything but processed foods from your diet. Everything in moderation, even…
What’s your take on soy?
