Show 1216: How Sugar Interferes With Healthy Decisions

In Stock
When we need to make healthy decisions about what we eat and drink, we need to find ways to deflect the allure of sugar for our brains.

The telomeres that cap our chromosomes are a good way to gauge biological aging. Dr. Elissa Epel, who studies aging and metabolism at UCSF, has found a link between soda consumption and cellular aging, even in young children (Childhood Obesity, April 2018). She and her colleagues took advantage of a natural experiment at the University of California, San Francisco, to see if making sugary beverages less accessible made a difference for people’s health.

Quite a few of the people who had been accustomed to consuming at least one sugary beverage daily had prediabetes. When the vending machines in their workplace no longer offered soda, their blood sugar levels were lower. Many people have trouble overcoming a soft drink habit, though, since sugar can interfere with healthy decisions in subtle ways.

How We Make Decisions:

Neurologist David Perlmutter and his son, Austin Perlmutter, MD, have teamed up to write Brain Wash: Detox Your Mind for Clearer Thinking, Deeper Relationships, and Lasting Happiness. They describe the three layers of the brain and the importance of the prefrontal cortex for decision making. But can we make healthy decisions when sugar is appealing to an older, deeper brain layer we may not even be aware of?

In addition, advertisers of products for children may take advantage of the lure of sweets. Are they brainwashing American kids? What could we do about that?

Bringing Your Brain Back into Balance:

Phineas Gage was a 19th century railroad foreman who survived a dramatic accident after an iron rod went through his skull. This story illustrates the importance of the prefrontal cortex. His was destroyed in the accident, and shortly after that, he acted quite differently. Reportedly, his friends hardly recognized him as the same man. However, later in life he partially regained his previous skills and temperament. That demonstrates our brains’ plasticity.

How can we use that adaptability to overcome the siren song of sugar in the supermarket? In summary, the doctors Perlmutter offer us some simple steps to help us make healthy decisions. And, finally, they offer us a peek into their own grocery carts.
