According to the video you watched concerning our brains on a junk-food diet, all of the following are true, EXCEPT:

A  Rats who are fed a toxic high-fat, high sugar diet become unable to follow rules as well as rats not fed such a diet

B  A brain exposed to a toxic high sugar and high fat diets have reduced neurogenesis and neuroplasticity

C  A junk food diet causes a failure in brain signaling of fullness, meaning we are more likely to overeat and gain weight

D  Reinforcement pathology describes the ability for our brains to adapt to a toxic junk food diet, then add new dopamine receptors, causing us to want more junk food to get more high

E  A high sugar diet causes brain inflammation in the hippocampus, interfering with learning and memory, only in people who are overweight or obese
