A new study states that nutrition (or lack thereof) in early childhood has lasting implications for intellectual development later in life, even when other factors, such as years of schooling, are accounted for.
I’ve always been convinced that nurture affects IQ more than we give it credit for right now. To truly close the achievement gap, we’ve got to broaden our scope and include pre-natal care, nutrition, and high quality childcare during the critical years from 0-3.
Think about how much the body develops from age 0-3. And the brain is part of the body. I imagine it develops in ways that lay a foundation for future intellectual development. The stronger the foundation, the stronger the development will be.
