Chicken
drumsticks are giving boron a leg to stand on as an element that may be
important for optimum bone growth in people. Studies of growing chicks show
that boron--found mostly in fruits, vegetables, legumes and nuts--can
partially compensate for a low vitamin D intake in bone formation.
Like
human children, chicks raised on a diet deficient in vitamin D develop
rickets, a bone deformity in which the actively growing ends, or growth
plates, are weak from lack of minerals. Adding boron to the vitamin
D-deficient diet significantly improved the accumulation of minerals in the
chicks’ growth plates, according to researchers with USDA's Agricultural
Research Service.
They
added several levels of boron to the chicks’ diets to approximate the range
people might get through typical diets. After four weeks, they inspected the
growth plates under a microscope.
Those closest to normal
came from chicks getting the highest level of boron--4.2 milligrams per
kilogram of feed. This is equivalent to the boron levels in a human diet
containing plenty of fruits and vegetables. Even in the chicks raised on diets
containing adequate vitamin D, the growth plates tended to mineralize better
when the animals got ample boron.
