I’ve seen so many infomercials for blenders that claim to “unlock” nutrients that our bodies aren’t otherwise able to absorb. Is there any truth to this claim and should I be blending more fruits and vegetables?
Getting a nutrition education from infomercials isn’t a good idea. As you can imagine, infomercials are designed to sell products and not to educate consumers. Often citing unpublished or unscientific studies, these infomercials create unsubstantiated marketing hype that’s aimed at getting you to open your wallet.
When it comes to blenders, nutritionists note that the “unlocking” claims are unsubstantiated. Blending foods doesn’t release nutrients in a way that your body couldn’t otherwise accomplish. In fact, our bodies are better than blenders. During digestion, food is broken down far more effectively than any blender could achieve. Moreover, these broad claims would need to be tested ingredient by ingredient, and the results would likely change from person to person based on their activity levels, age and diet.
The notable exception is individuals who suffer from throat or digestion conditions that prevent ingestion of solid foods; for these individuals, blenders can represent a huge advantage.
Of course, none of this is to say that you shouldn’t buy a blender. If the convenience and taste of blended foods inspires you to eat more fruits and vegetables, then a blender can certainly be a smart and worthwhile purchase. Just remember that blended calories add up fast. To cut calories, use water or unsweetened almond milk as your smoothie base and avoid adding sweeteners like agave nectar or honey. Go heavy on the veggies and stay away from smoothies made with ice cream or frozen yogurt.
