A study found that nut-consumers demonstrated a lower body weight, body mass index (BMI) and waist circumference
Dieters often dismiss them because of their high fat content, but research suggests that snacking on nuts can help keep you slim.
A study found that those who consumed varieties such as almonds, cashews and pistachios demonstrated a lower body weight, body mass index (BMI) and waist circumference compared to non-consumers.
They were also at lower risk of developing heart disease, type 2 diabetes and metabolic syndrome.
Experts are now recommending a daily intake of 1.5 ounces, or three tablespoons of nuts as part of a healthy diet.
Lead researcher Carol O'Neil, from Louisiana State University, said: 'One of the more interesting
findings was the fact that tree nut consumers had lower body weight, as
well as lower body mass index (BMI) and waist circumference compared to non-consumers.
'The mean weight, BMI, and waist circumference were 4.19
pounds, 0.9kg/m2 and 0.83 inches lower in consumers than non-consumers,
In the study, published in the Journal of
the American College of Nutrition, researchers compared risk factors
for heart disease, type 2 diabetes and metabolic syndrome of nut
consumers versus those who did not consume nuts.
They used data from 13,292 men and women
participating in the 1999-2004 National Health and
Nutrition Examination Surveys (NHANES).
Nut consumers were defined as those who ate more than one quarter of an
ounce a day.
Tree nut – almonds, Brazil nuts,
cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and
walnuts – consumption specifically, was associated with higher levels of good cholesterol and lower risk of chronic diseases including heart disease.
In addition, it was also linked to a lower prevalence of four risk factors for metabolic syndrome: abdominal obesity, high blood pressure, high blood sugar levels and low good cholesterol levels.
Dr O'Neil adds: 'Tree nuts should be an integral part of a healthy diet and encouraged by health professionals—especially registered dietitians.'
Maureen Ternus, executive director of the International Tree Nut Council Nutrition Research & Education Foundation (INC NREF), also congratulated the recent data.
She said: 'In light of these new data and the fact that the FDA has issued a qualified health claim for nuts and heart disease with a recommended intake of 1.5 ounces of nuts per day, we need to educate people about the importance of including tree nuts in the diet.'
