Soy Protein Isolate, and the Danger of Added Sugar

Happy Thursday everyone!! Only one more day until Friday, aka move-in day for Nick and I! Because we have lived in this tiny apartment for the last 3 years, we barely have any furniture. We plan to live without much furniture for at least a few months. It will be…interesting.

Some of you still have questions about bananas in the fridge. I’d like to clarify something. If your drawer is set at a high humidity, your bananas will get soft faster. You need to make sure it’s set at low humidity (some fridges will say, others won’t, but I’m not really sure how you find this out, sorry!). In general, just keep them on the counter if you don’t know about the humidity, but always separate them if you want them to last longer.


A couple of you have asked me about soy protein isolate. What is it? Should it be avoided? Soy protein isolate is exactly as the name implies; isolated soy protein. It is made by removing the beneficial fat (omega-3) from the soybean, as well as the dietary fiber. What is left is the soy protein (isolated). It’s used in many protein supplements, bars, and powders.


You’ll find it in many other foods too, just start looking at the ingredient lists. In my opinion this is not something that should necessarily be avoided (I know I’ve heard about some bad chemicals in soy protein isolate, but I don’t know enough about this to give you an honest opinion). Do keep in mind, however, that you don’t want to eat too much because soy protein isolate has many isoflavones (phytonutrients that may help prevent breast cancer, but which may have a link to breast cancer if you consume too much). If you stay away from processed food (or at least consume them in moderation), you won’t be consuming too much soy protein isolate, as it’s really only found in processed foods! I try to get 25-30 grams of soy protein each day, but the best sources of soy protein are foods such as edamame, tofu, and tempeh, NOT processed foods with soy protein isolate.

Added Sugars

Remember back in 1990 when the “low fat craze” hit America? Ok, maybe you don’t remember, but I do! That’s about the time that America started to blimp and gain a bunch of weight. Ironic, right? Basically, as I’ve said in previous posts, once companies started removing the fat, they replaced it with sugar and salt. In reality, that just made most products even more unhealthy!Soy Protein Isolate 1

A study in the Journal of the American Medical Association was published recently, which associated added sugar (found in so many foods these days) with decreased HDL (good) cholesterol and increased triglycerides. These are two important risk factors for heart disease. Check out the research here.

Just as a reminder, let’s look at all of the sources of sugar in the bar below:

– Evaporated cane juice syrup

– Brown rice syrup

– Evaporated cane juice

– Pear juice concentrate

– Honey

– Barley malt syrupKASHI BAR 1

Just to be fare, here’s a Fiber One bar:

– Sugar (x4)

– Malt

– High maltose corn syrup

– High fructose corn syrupKASHI BAR 2

** Both Kashi and Fiber One are companies I respect, quite a lot. Most of their products are fantastic. Their bars? Well, that’s another story. I’m not a fan. But in reality, as I said before, I am not a fan of most bars. **
