This week we move into the arena of preventive cardiology when we review a recent report from the team at Northwestern and Princeton on the impact of early childhood food insecurity on cardiovascular health of people in young adulthood. How does food insecurity in young childhood impact the cardiac health of adults? Why is most of the impact seen on BMI but not other measures of cardiovascular health. How can food programs that support improved food and nutrition security work to improve long term cardiovascular health of children and adults? Do the benefits of such programs outweight their costs? Dr. Nilay Shah of Northwestern University shares his deep insights into his work and these questions this week.
