Foods that Act Like Sugar
I write a lot about sugar and foods that act like sugar in this blog. Lately, I’ve been getting a few questions about what I mean by “foods that act like sugar,” so here is the explanation and it all start with an understanding of the glycemic index.
The Glycemic Index
By now, most people have heard of the glycemic index, but I’ll take a moment to explain it.
The way the glycemic index works is that a scientist will measure the blood sugar of a volunteer and then feed that volunteer a single food. After two or three hours, the volunteer’s blood sugar is measured again. What scientists have discovered through this kind of testing is that certain foods increase blood sugar a little, others increase blood sugar moderately, and still other foods increase blood sugar dramatically.
While there are complicated glycemic index charts that show hundreds of foods, here is a typical one:
What you want to notice about this list is that sugars (left-hand column) are mostly in the high top part of the chart. Sucrose (table sugar) and glucose are always found near the top, but, here is the kicker: so are white rice, pancakes, bread, corn flakes, crackers, parsnips, potatoes and many other foods. These are the Foods That Act Like Sugar in your body.

Is fresh squeezed orange juice okay or all fruit juice fresh or bought?
Hi Brenda,
No fruit juice (both fresh and frozen) are not allowed as they act like sugars in our bodies.
Best of luck!

Thank you.
Sorry; another question… I didn’t see anything about quinoa. Is that okay?
Ask as many questions as you need to, glad to answer.
Quinoa is low-glycemic, so it fits the diet. I would use it sparingly.

Thank you. Another one… Soy milk & almond milk in teas & smoothies? Is that ok? I’ve noticed soy milk & almond milk have added cane juice.
also, I use 2 different protein powders. 1 is Vi-shake from Visalus that has some added sweetener. The other is vega which I don’t think does. I have to double check.
Thank you
Brenda,
You should be able to find unsweetened almond milk. I’m not a big fan of soy, but there should be an unsweetened version as well. I love coconut milk from So Delicious and they have an unsweetened version. I don’t don’t Vi-shake, but the Vega products do contain sugars. If you are looking for a protein powder, choose a straight protein with nothing else added.
Hope that helps!
Scott
