participants were categorized into cohortspecific quintiles of intake of energy-adjusted
dietary variables.
The researchers identified 995 ALS cases
over the follow-up. There was a reduced risk
for ALS with greater ω-3 PUFA intake.
Comparing the highest to the lowest quintile,
the pooled, multivariable-adjusted relative
risk (RR) was 0.66 (P < 0.001 for trend). This
inverse association was based on both
consumption of α-linolenic acid (RR, 0.73; 95
percent confidence interval, 0.59 to 0.89; P =
0.003 for trend) and marine ω-3 PUFAs (RR,
0.84; 95 percent confidence interval, 0.65 to
1.08; P = 0.03 for trend). Intakes of ω-6 PUFA
were not associated with ALS risk.
"Consumption of foods high in ω-3 PUFAs
may help prevent or delay the onset of ALS,"
the authors write.

use of these devices in the United States can
lead to severe economic, civil, and criminal
penalties," the authors write.

ietary Fatty Acids
May Reduce ALS Risk
Amyotrophic lateral sclerosis
(ALS) may be delayed or
prevented with the consumption
of foods high in ω-3 polyunsaturated fatty acids
(PUFAs), according to a study published in the
July 16 issue of JAMA Neurology.
Kathryn C. Fitzgerald, from the Harvard
School of Public Health in Boston, and
colleagues analyzed longitudinal data from
1,002,082 adults (479,114 women and 522,968
men) participating in five prospective cohorts
(the National Institutes of Health-AARP Diet
and Health Study, the Cancer Prevention Study
II Nutrition Cohort, the Health Professionals
Follow-up Study, the Multiethnic Cohort Study,
and the Nurses' Health Study). Food frequency
questionnaires were used to assess diet, and
