Crushed fruit or veggie smoothies, it has to be good for you right? Wrong! Well I learned the hard way that a “healthy” smoothie is loaded with SUGAR, and very often can have more sugar than a 12oz can of coke (39g/can). That number has the potential to go up as high as 95g of sugar depending on if you add any “boosts.”
Now, I’m not a registered dietician or nutritionist, but I’ve got a decent understanding of how the body works at this level, and I know a massive influx of sugar (regardless of its fructose or sucrose) into your body spikes your blood sugar in a manner that is nothing but bad news (IT’S IMMEDIATELY STORED AS FAT……)
So, you’re looking for a healthy snack, and in the process you have the potential to put well over two cans of Coke’s worth of sugar in your body. Sign me up! Do it often enough, and that amount of sugar will add weight on you like nobodies business and here’s why.
“The faster sugar enters the bloodstream, the less goes to muscle, and the more goes to FAT,” says Dr Wilson in his book What, When and Water: Nutrition for Weight Loss Wellness. “Eating rapidly digesting carbs will spike blood sugar and insulin levels resulting in a blood sugar crash with an increased hunger once the sugars are cleared into fat stores.”
Wilson also says when you replace a natural food with a processed food (juicing falls into this category) you “reduce the fiber and nutrient content significantly and make the resulting food one step closer to pure sugar.”
Microbiologist and NASM-CPT Lea Swenson agrees with Wilson.
By ingesting foods in a juiced state, you violate the glycemic index in big way. Foods with protein and fat have a much lower GI rating than those with simple sugars. Swenson also said if you “flood the bloodstream with sugar, your pancreas floods your bloodstream with insulin in an attempt to deliver the glucose to your cells.” Do this enough, and you become “insulin resistant.” When this happens, your muscles will absorb fewer calories. The ones your body does absorb have a much higher likelihood of going straight to fat storage.
“Circulating glucose fuels our brain (continuously) and goes to short-term storage in the liver and muscles as glycogen, ” says Swenson. “Once these glycogen stores are full the excess goes to long-term storage as fat.” If you have a hard time losing weight when you’ve got carbohydrates in your diet, you are probably insulin resistant or your body may be addicted to sugar. There is a way around this.
