Hi. As DS gets closer to the six month mark I've been reading up more on starting solids. Came across this info from the AAP on their site healthychildren.org that I didn't know and wanted to share since some of us had discussed making our own baby food.
NOTE: If you make your own baby food, be aware that home-prepared spinach, beets, green beans, squash, and carrots are not good choices during early infancy. They may contain large amounts of nitrates. Nitrates are chemicals that can cause an unusual type of anemia (low blood count) in young babies. Commercially prepared vegetables are safer because the manufacturers test for nitrates. Peas, corn, and sweet potatoes are better choices for home-prepared baby foods.
I knew beets absorbed a lot of stuff - good and bad - from the soil which is why it requires frequent crop rotation but I didn't know about the others. I'll have to keep that in mind when I'm grocery shopping. The above info came from this link:
