By chocolate I means dark/bitter chocolate (85%). The dosages need to be at least 50-100 g per day (~ 2 oz) to replicate studies where they resulted in improvement and some patients being able to return to work. Note 85% chocolate has as much sugar in it as an apple, so the sugar hit is low. You may find that after a day or two, it is no longer a “treat” but something that you have to work on consuming the required dosage.
What does chocolate do? According to pub med studies:
- changes metabolism at 40g/day
- after 2 weeks, microfloras(gut bacteria is changed
- reduce inflammation cytokines such as TNF, IL-10, as well as IgE
- improves blood flow in the brain
- reduces coagulation
- reduces nitric oxide(NO) release – which various researchers deem very important (Martin Pall and others)
- alters lactate, citrate, succinate, trans-aconitate, urea, proline, adrenaline, DOPA, 3-methoxy-tyrosine, methylamines, p-cresol sulfate, hippurate, etc .
And last, in terms of it’s impact on CFS patients, it improves symptoms with 20% of the patients in the study being able to return to work! Read the study yourself:
