Caffeine Increases Cortisol (Stress). Should It Be Avoided?

[davekm]

I've looked at some studies on this subject:

 

Increase cortisol

 

3.5 mg/kg caffeine potentiated stress-related increases in plasma epinephrine and cortisol stress, more than doubling the responses observed in the control condition. (average intake 500mg)

225 mg daily also increased cortisol response to a task.

300mg daily causes reduced, but not eliminated response.

260 mg increased cortisol and adrenocorticotropic hormone in chronic users

 

No effect

 

75 -150mg had no effect on salivary cortisol levels in 12 hr withdrawn (100-500 average intake)

250mg & 500mg no changes in hormones (150-450)

chronic 100mg no effect

300mg no difference students (200-700)

 

What am to conclude from this? I myself only take in 150mg per day.

Plants produce it as a pesticide.

I suppose you don't eat peppers, garlic, or many other plants either.

 

Few things are quite as black and white as you seem to be making this out to be. :rolleyes: indeed
