Due to the high fat content of regular soy milk and isolated soy protein being in some brands of the low fat soy milk, I have simply stopped buying it. We mainly used it on cereal, anyway -- and, since I mostly MWL and usually do not eat cold cereal, it was mainly just for my husband's cereal.
The first day without soy milk, I made banana milk (simply mashed banana and some water mixed together -- sorta like a thin smoothie with tiny lumps of banana in it) for my husband. He actually liked it on his cereal!!!
Then I got brave and whizzed a raw carrot with some water into as close to a liquid state as possible
in a blender (and did NOT strain it) and then threw in some banana and whizzed it just little bit more and got banana-carrot milk. He likes that, too -- as long as I do not get too much carrot and not enough banana in it, that is.....
I generally use one medium-size carrot to one medium-size ripe (but not overripe) banana in a total of about 1&1/2 to 2 cups of banana-carrot milk.
My husband eats plenty of fruit but does not eat enough veggies. I feel that his using banana-carrot milk on his cereal on some mornings helps him to increase his veggie intake.
