Eat your fruits(you digest fiber too instead of drinking pure liquid sugar straight. Quick absorptions of glucoses lead to massive blood sugar spikes/fluctuations. Fruit juices are tasty because they contain a higher concentration of natural sugars that – although better than artificial sugars – can easily spike your blood sugar. If you’re craving some natural sweetness, it’s better for you to bite into one whole, raw fruit (get your fiber and antioxidants !) than to drink the equivalent of ten in a fruit juice full of fructose and sugar.
Drink your veggies. The ideal ratio in juicing : 90% vegetables and 10% fruits. Skip apples and pears and replace them with oranges. A orange should should be the only fruit of choice in your juices. Citrus fruits all the way. My personal juicing recipe: kale, collard greens, bell peppers, cucumber, ginger, lemon, orange, parsley, cilantro and carrots.
Frozen Berries(blueberries, raspberries, cranberries, blackberries, cherries) are the only fruits you should use for blending smoothies because they are low carb/sugar fruits with mad antioxidants and phytonutrients. Semi-green, semi ripe bananas should be the only exceptions. I drink kale smoothies.
