Thanks for the perspectives.
mumkimum, I agree with pairing it with something else, like a muffin or bread with nut butter.
catnip, one of the 2 nights I was referencing, we also had popcorn with nutritional yeast.
I just think that for the summer time, it can be a light meal, although our smoothies do tend to be really heavy (thick and substantial) with loads of good, healthy stuff in them. And our family really enjoys them.
I wonder if some of the people who are saying no, they would never give a substantial green smoothie for supper (which in my opinion is wholesome and my family, at least at this point LOVES them), would ever give Kraft mac & cheese or something processed or much less nutritious on occasion? In my mind, if I'm really pressed for time and have kids who need to eat (yesterday!), smoothies are quick to whip up and are super healthy. Now, to be fair, I do think in my original post/poll question I did say "JUST green smoothies for supper." But I do also give snacks after supper: fruit, nuts, seeds, whole grain crackers, etc.
crunchy_mommy, do you mind expanding just a little on your belief that we should eat, not drink a majority of our calories? I'm sincerely interested in your reasoning. In my mind, as long as we're getting adequate nutrition, it doesn't matter so much if we've eaten or drank it. I feed my sons oatmeal with fruit or berries for breakfast normally, but I feel better about the fresh juice that I make them to drink for some reason. Maybe because I feel that it's so healthy for them. My kids only drink fresh vegetable/fruit juice, green smoothies and occasionally soy milk. Otherwise, I give my older toddler water the rest of the day. My 12 month old still nurses a lot, so I give him less water than my toddler who also nurses, just not as much.
Also, while I give my kids green smoothies every day, it is generally given as a snack.
Thanks again for the perspectives!
