To smoothie or not to smoothie? The skinny on blending your fruits & greens

To smoothie or not to smoothie?
With an upsurge in 'smoothies' and
'cleanses' all over the web this time of year, for health, 'detox', or
weight loss, it's good to be mindful of why you might not want
to make smoothies a part of your daily diet. Especially f you are trying
to lose weight, or keep your weight in check, or have blood sugar and
triglyceride challenges. Or satiety challenges for that matter.
2 reasons to reconsider smoothies
- decreased satiety as compared to whole foods
- increased destabilization of blood sugar compared to whole foods
Blending and whirring vegetables and fruits as
happens in the making of smoothies disrupts the fiber of the natural
food. This disruption impacts the satiety value
of that food. It seems, doesn't it, that all of the fiber that was
there before you blended it should be there in your smoothie. After
all, you didn't extract the juice from the apple, the spinach, the
blueberries - you just blended it up. Fiber is fiber, right?
It doesn't work that way. Disrupting
the fiber, as happens in the process of making a smoothie, exposes more
of the surface area of the food. This means it is absorbed more
quickly, making it more likely that it will effect your blood sugar and
insulin levels. Not only that, but the more of it you want to consume.
When the food is whole, or even chopped, we have more invested in the
project of eating by chewing, an important part of the digestive and
satiety process.
Calorie consumption comparisons between whole foods, blended foods, and juiced foods with fiber restored
These numbers of analysis should help.
Studies comparing caloric intake at a meal following the consumption of
either nothing (no preload), an apple, applesauce, apple juice (with
fiber added), apple juice (no fiber added) delivered the following
results.
