If I put a whole apple with its skin or raspberry with its seed, or orange in a mixer-grinder, how or when exactly do I lose the skin, seeds or membranes during the process of making juice?
One difference is of course that when you eat the fruit, you chew it. This takes time and this may give some "food coming, hunger over" signal to the brain. Smoothies are so easy to drink that you might be getting way more fruits than you would normally eat.
What you're doing is not "freshly squeezed".
Not a native English speaker, so trying to understand the difference.
