Are Your Protein Bars Killing You?

We are the generation that counts calories. We avoid fats. And we try to substitute our sugars with every low-calorie option we can find. After all, we want to be healthy, right? Here’s the truth about all those calories we’re saving, thinking it’s making us “healthy”: our generation needs to seriously shape up our food choices and start educating ourselves about what we are putting into our bodies every day.

Let’s talk about a little sweetener called sucralose. What is sucralose?

Sucralose is a strand of chemicals that has been approved by the FDA as 98% pure. 98% percent sounds pretty good, right? Wrong! That little 2% could be causing major health concerns in your body. So what could possibly be so bad that you need to worry about that small 2%?

It contains heavy metals like lead, arsenic, triphenilphosphine oxide, methanol, chlorinated disaccharides, and other potentially dangerous substances.

What concerns have been raised about these chemicals? What problems might they cause?

One study on sucralose showed an increase in glycosylated hemoglobin (meaning damage to the oxygen carrying part of a red blood cell). Research in animals has shown:

  • Up to 40 percent shrinkage of the thymus gland (critical for the response to disease—the “heart” of our immune system)
  • Enlarged liver and kidneys
  • Atrophy of lymph follicles
  • Reduced growth rate
  • Reduction of healthy stomach florid

The reality is that there has not been enough research done on sucralose to establish that it’s safe for humans to consume, yet we are putting it into our protein bars, gum, snack items, and drinks.

Consider the problems that sucralose could be causing and put into perspective what this will do to your body in the long run instead of just thinking about what it’s doing to help you reach your possible goal of losing weight. When you put your body through this type of stress in your kidneys, when you have low healthy stomach flora, and when your immune system isn’t working the way it should be, your training results will decline and your body will go into a state of shock hormonally over the junk that’s being fed to it. So before you go and grab that quick snack option or that coffee that claims to only have a small amount of calories, take a good hard look at what you’re actually consuming.  A healthy body is about smart choices, not a quick easy fix … one that maybe killing you.

    Hi Rachel, made me think twice (thrice, etc!) about that Diet Coke I am craving. It’s an uphill battle, the diet coke addiction, but I am determined!

    What is your opinion of Sorbital? I use Nuun tabs and is sweetened with sorbital. I like them cause they have a bit flavour and not sweetened to death by stevia. What would u recommend for a drink hydrator with a higher amount of sodium?

      Hi Tanya,

      Thanks for your comment. I’m not really familiar with Sorbital. I would recommend making your own hydrator. I put up an awesome pre workout drink. Try that one
