Our general morning breakfast includes kefir smoothies. The kiddos love them and I know they are getting a great boost right when they need it. The best part is that whatever fresh fruit I have that's frozen I can throw right in, and every now and then I add some spinach for an extra boost. I don't juice just plain and simple due to cost and the clean up aspect of it. I love fresh juices but I rarely have the time in the morning to go through all the hassle of bringing stuff out. These allow me to add all my stuff and have it ready in 5-10 minutes.
For those of you that don't know what kefir is I really encourage you to go research it. The reason I started was I saw my sister in law making it on her counter and got curious as to whether it really was "all that". So I went home and l looked it up, pros and cons, what it was and why it's beneficial. I found very few cons, which always makes me more interested, so I decided to give it a try. I use actual kefir grains I bought off Amazon from a trusted buyer (I love that I can check reviews) and started out. Being you can buy it in a store pre made seems like the way to go BUT in researching found that the quality of that kefir is so low that you can't use that kefir to make a new batch. Kefir is like yogurt in the fact that it's a culture so you should theoretically be able to do that. You can do it with my fresh stuff just not the store bought. SO I now make kefir daily to use in my smoothies. I know where all the ingredients come from being we try to be less processed in what we eat, AND I know that I don't add anything I don't trust.
If you are interested in more information about starting kefir or benefits of water/milk kefir I highly suggest checking out the links to healthy cultures in my "favorite links" area. Also I encourage anyone that was or is as reluctant as me to using raw local honey to talk w/ different local bee keepers in your area. I have learned a lot about raw honey from conversations with them and found it interesting to do that and then do more research from there.
