The WHY Behind the Findings
 

Calcium and Weight Loss * Trans Fats and Heart Disease

Ever since I was a young girl and babysat toddlers, I’ve always marveled at young children’s natural curiosity.  Have you ever played the why game with a toddler?  No matter how many answers you give, there is always the very predictable response: Why?  I clearly remember playing several why games with my nephews.  Why do you have to leave?  Because I have to go to work and if I don’t leave right now I’ll be late. Why do you have to work?  Because I have bills to pay.  Why do you have bills? — You get the picture.  For this month’s thought bullets, I did some research to try to answer the why question behind some nutritional news hitting the headlines frequently in recent months: a possible link between increased calcium intake and weight loss and the reason trans fats are associated with an increased risk of heart disease.
