Home' Trinidad and Tobago Guardian : January 13th 2014 Contents A new US study adds to growing evidence that
nuts---once considered too fattening to be healthy---
may in fact help keep weight down, in addition to
offering other health benefits.
Researchers found that study participants who ate
the most tree nuts---such as almonds, Brazil nuts,
pistachios and walnuts---were between 37 and 46
per cent less likely to be obese than those who ate
the fewest tree nuts.
People who ate the most nuts were also less likely
to have a suite of risk factors known as metabolic
syndrome, which is tied to increased risk of heart
disease and diabetes.
"This is another study that shows there is an asso-
ciation between eating nuts and not being obese and
having less tendency to have metabolic syndrome,"
Dr Joan Sabaté told Reuters Health.
Sabaté is the study s
senior author from Loma
Linda University in Cali-
The study, which was
published online in PLOS
ONE, was partially funded
through a grant from the
International Tree Nut
Research and Education
Foundation (INC NREF).
In another recent study,
also funded by INC NREF,
researchers found that
people who reported eating the most nuts were less
likely to die over a 24-year period than those who
ate the fewest nuts.
While such evidence can t show that nuts cause
the differences seen between people who love them
and those who pass them by, there are reasons to
believe nuts provide a direct benefit, Sabaté said.
For example, nuts are high in unsaturated fat, which
is known as a "good" fat compared to the saturated
fat found in animal products. The high protein content
of nuts may also lead people to feel fuller and eat
less unhealthy foods. They also contain of host of
other nutrients and plant chemicals that are beneficial
to health, Sabaté said.
For the new study, the researchers used data on the
diets of 803 Seventh-day Adventist men and women
in the US who were already enrolled in another study.
Overall, those who ate a lot of tree nuts---about
16 grammes (half an ounce) per day---were just a
little over normal weight, on average, compared to
those who ate few or no nuts and were seriously
overweight or obese.
A normal body mass index (BMI)---a measure of
weight in relation to height---for an adult falls between
18.5 and 24.9, according to the US Centers for Disease
Control and Prevention. Overweight people have
BMIs between 25 and 29.9 and a BMI of 30 or more
is considered obese.
People in the study who ate the most nuts averaged
BMIs of about 27 while those who ate the least---less
than five grammes of tree nuts per day---averaged
BMIs of 29 to 30.
The researchers also found that one third of the
participants in the study had metabolic syndrome,
which is defined as having three or more conditions
associated with heart disease and diabetes risk. (Those
include being obese, having high blood pressure and
high cholesterol, and having a large waistline).
For every one-ounce serving of tree nuts consumed
per week, however, a person s risk of having metabolic
syndrome dropped by seven per cent.
Jeffrey Blumberg, a professor of nutrition at Tufts
University in Boston who was not involved in the
new research, said it is consistent with a number of
previous studies showing that including nuts in one s
diet is beneficial.

"It really is at a point now where I think there is
a large body of evidence and is---I would even say---
a consensus of nuts being a healthful food choice if
consumed in reasonable amounts," Blumberg said.
