Abstract

Objective: Prior research has suggested the possible role of oxidative stress in the pathogenesis of amyotrophic lateral sclerosis (ALS). Prospective data examining dietary antioxidants such carotenoids and vitamin C are limited. Methods: Risk of ALS associated with carotenoid and vitamin C intake was investigated in 5 prospective cohorts: the National Institutes of Health–Association of American Retired Persons Diet and Health Study, the Cancer Prevention Study II Nutrition Cohort, the Multiethnic Cohort, the Health Professionals Follow‐up Study (HPFS), and the Nurses Health Study (NHS). ALS deaths were documented using the National Death Index, and confirmed nonfatal ALS cases were included from HPFS and NHS. A total of 1,153 ALS deaths occurred among 1,100,910 participants (562,942 men; 537,968 women). Participants were categorized into cohort‐specific quintiles of intake for dietary variables. We applied Cox proportional hazards regression to calculate cohort‐specific risk ratios (RRs), and pooled results using random‐effects methods. Results: A greater total major carotenoids intake was associated with a reduced risk of ALS (pooled, multivariate‐adjusted RR for the highest to the lowest quintile = 0.75, 95% confidence interval [CI] = 0.61–0.91, p for trend = 0.004). Individually, higher dietary intakes of β‐carotene and lutein were inversely associated with ALS risk. The pooled multivariate RRs comparing the highest to the lowest quintile for β‐carotene and lutein were 0.85 (95% CI = 0.64–1.13, p for trend = 0.03) and 0.79 (95% CI = 0.64–0.96, p for trend = 0.01), respectively. Lycopene, β‐cryptoxanthin, and vitamin C were not associated with reduced risk of ALS. Interpretation: Consumption of foods high in carotenoids may help prevent or delay onset of ALS.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
