Super size me or the movie where the guy eats fast food only for a month was on.
He actually wakes up and feels as though he is having a heart attack. He goes to his Dr. and everything, as far as heart attack, appears normal - but he is advised to stop eating only fast food. (This was before fast food places had healthier choices available).
This was an important reminder how junk food might impact anxiety (he did not panic - but many would have) symptoms just from junk food.
Also a lot of anxiety d/o people are taken off all sugar (avoiding high and low blood sugar) and weaned off all caffeine.
Healthy eating, low sugar, low or no caffeine is very helpful in anxiety d/o.
