MORE FINDINGS ABOUT ARTIFICIAL SWEETENERS
Research studies show:
•
People who drink diet
soda tend to gain more
weight
•
Using artificial
sweeteners may
contribute to obesity &
diabetes
•
The types of gut bacteria
are different in people
who use artificial
sweeteners
Why? Some hypotheses:
• Sugar tastes sweet and satisfies hunger;
• Artificial sweetener only tastes sweet but
doesn’t satisfy hunger
• Knowing you’re drinking diet soda make
you think you can eat more calories
• The sweet taste of artificial sweeteners
increases sugar cravings and appetite
• Artificial sweeteners may trick the body
into releasing insulin so the body doesn’t
metabolize sugar as well
• Changing the gut bacteria may disrupt
the body’s ability to regulate blood sugar
What can be done?
• Limit how much artificial sweetener you eat
• Diet soda is a treat not something you drink every day
• Recommendations for how much artificial sweetener we can safely eat
