Juicing is stupid. Just use a regular blender that way you keep all the fiber/pulp and beneficial parts of the fruits and vegetables.
Humans are so silly. They want the easy way out of everything and end up eliminating everything that's actually beneficial.
That said I have a blender and like to make smoothies with different combinations of grapefruit, strawberry, blueberry, spinach, banana, etc. Sometimes I'll add protein powder or use milk as well. But note this is just a blender so it doesn't eliminate all the fiber.
I think one of the healthiest I've been was my junior year of college my diet was the same every week. Pasta with onions, peppers, tomatoes and chicken everyday. Protein smoothie with spinach, blueberry, and protein powder every day. Huge amounts of water. My body started getting so chiseled after 3 months that people were asking me if I played college football when I would go to the bar. Also something about my smoothies seemed to clear up my skin, make my hair nicer, and made my eyes lighter. I'm black and have dark brown eyes but my eyes seemed to lighten a bit in color after a few months of having that smoothie every day. Mainly in the sunlight but one time my roommates girlfriend asked if I was wearing contacts cuz she said my eyes were so light.
Very interesting. I need to get back in that mode.
