Walnuts and Longevity
According
to a study2 by researchers from the Harvard T.H. Chan School of Public
Health, higher walnut consumption – both in terms of the amount and
frequency – may be associated with a lower risk of death and an increase
in life expectancy among older adults in the U.S., compared to
non-walnut consumers. Eating five or more servings per week was
associated with a 14% lower risk of death (from any cause), 25% lower
risk of dying from cardiovascular diseases, and a gain in about 1.3
years of life expectancy, compared to non-walnut consumers.
Walnuts and Physical Function
Findings
published in The Journal of Nutrition suggest that consumption of 1-2
servings of walnuts per week (1/4 cup per serving) was associated with
reduced risk of developing impairments in physical function in older
women, which may help to maintain independence throughout the aging
process. Researchers looked at data from 54,762 women in the Nurses’
Health Study, which tracked women for over 30 years. This paper
emphasized that overall diet quality, rather than individual foods, may
have a greater impact on reducing risk of physical function impairments.
Walnuts and the Fight Against Alzheimer’s Disease
An
animal study published in the Journal of Alzheimer’s Disease found that
a diet including walnuts may play a role in reducing the risk of
Alzheimer’s disease. The study found significant improvement in learning
ability, memory, reducing anxiety, and motor development in mice fed a
walnut-enriched diet.
Walnuts and Memory
A publication in The
Journal of Nutrition, Health & Aging revealed that eating walnuts
was associated with improved performance on cognitive function tests,
including those for memory, concentration, and information processing
speed. Participants included adults ages 20-59 as well as 60 and over.
Mediterranean Diet and Cognition
Eating
a Mediterranean diet supplemented with olive oil or nuts (primarily
walnuts) may reduce the risk of age-related cognitive decline in an
older population, according to a study published in the Journal of the
American Medical Association Internal Medicine.6 Participants, a
subcohort of the Prevención con Dieta Mediterránea (PREDIMED) trial,
were randomly assigned to a Mediterranean diet supplemented with mixed
nuts (15g walnuts, 7.5g almonds, and 7.5g hazelnuts per day) or extra
virgin olive oil (at least 50g or 4 tablespoons per day), or a low-fat
diet (control group). The study found that participants who consumed a
Mediterranean diet with nuts, including walnuts, showed improvements in
memory compared to a control diet.
