Here's a new study on the roots of allergy. Researchers found that lower cholesterol in infants lead to higher rates of allergy over the following 20 years.

This is why progressive doctors now have preganant women supplementing with omega-3 fish oil throughout pregnancy. This type of "preventive medicine" can help put a child on a healthy trajectory.
