Objective We aimed to ascertain the influence of the consumption of coffee and tea on Amyotrophic Lateral Sclerosis (ALS) progression rate.

Background ALS is a devastating and still untreatable motor neuron disease; nutritional factors may impact the disease progression rate.

Design/Methods A multicenter cross-sectional study. We recruited 241 patients, 96 females, and 145 males; mean age at onset was 59.9±11.8 years. According to El Escorial criteria, 74 were definite ALS, 77 probable, 55 possible and 35 suspected; 187 patients had spinal onset and 54 bulbar. Patients were categorized into three groups, according to ΔFS (derived from Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised score) and disease duration from onset): slow progression rate (N=81), intermediate progression rate (N=80) and fast progression rate (N=80).

Results Current coffee consumers were 179 (74.3%), 34 (14.1%) were non-consumers, 22 (9.1%) former consumers, whereas six (2.5%) consumed decaffeinate coffee only. The log-ΔFS was weakly correlated with the duration of coffee consumption (p=0.034), but not with the number of cups-year (p=0.932). Current tea consumers were 101 (41.9%), 6 (2.5%) were former-consumers, and 134 (55.6%) non-consumers. Among the 107 current and former consumers, 27 (25.2%) consumed only green tea, 51 (47.7%) other types of tea and 29 (27.1%) both. The log-ΔFS was weakly correlated only with the duration of other types of tea consumption (p=0.028), but not with the number of cups-year.

Conclusions Our study does not support the hypothesis that coffee or tea consumption is associated with progression of ALS.
