New Study Underscores Value of Nutrient-Dense Walnuts in Weight Management
Thursday December 15, 6:17 pm ET
LOMA LINDA, Calif., Dec. 15 /PRNewswire/ -- When it comes to weight
management, the powerful health benefits of walnuts cannot be
outweighed. According to experts, eating a few walnuts (4-6 walnut
halves) before meals decreases levels of hunger and may cause people to
eat less at meals.
"Walnuts help alleviate hunger and are naturally nutrient-dense, meaning
you consume many essential nutrients for a relatively small percentage
of daily calories," said Joan Sabate, MD, MPH, DrPH, chair and professor
of nutrition, department of nutrition, Loma Linda University School of
Based on new Loma Linda University research published in the November
issue of the British Journal of Nutrition, Dr. Sabate explains, "If
people substitute walnuts for other calories, then eating walnuts will
not lead to weight gain, and may lead to improvements in other
indicators of health, such as a decrease in LDL cholesterol."
In addition to aiding with satiety, walnuts provide essential nutrients
including protein, fiber, vitamins, minerals, antioxidants, and
heart-healthy omega-3 fatty acids. It is the synergy of these
ingredients that make walnuts unique among tree nuts.
The randomized cross-over field trial included two six-month diet
periods, a control diet and a walnut-supplemented diet, with ninety
participants (50 females; 40 males) aged 30-72 years.
During the walnut phase, study participants were simply asked to eat
1-1.5 ounces of walnuts each day. The average weight gain during the
walnut phase was insignificant at only 0.4 kg (less than 1 pound) over
Co-investigators in the study included Zaida Cordero-MacIntyre, Gina
Siapco, Setareh Toabian and Ella Haddad.
In 1993 clinical trials, Loma Linda University was the first to find
that walnuts in a controlled diet reduced LDL (bad) cholesterol and
heart disease risk significantly more than the Step 1 diet that was then
recommended by the American Heart Association. Subsequent studies
worldwide have consistently shown that walnut consumption is associated
with reduced risk of CVD.
