A
new study suggests cutting calories by about a third could protect
nerve cells from damage caused by reduced blood flow. Medical re-
searchers at Washington University in St. Louis studied nerve cells
from rat eyes. The investigators found that feeding rats 30 to 40
percent less food than normal reduced the animals' nerve damage
by about 30 percent to almost 50 percent. "Whether an observation
in rats will apply to humans is not known," says researcher
Arthur Neufeld. "But when we combine our findings with those
from other studies, we see a pattern. It suggests that eating fewer
calories may lead to a longer and healthier life." Prior studies
found that animals on very low-calories diets tend to live longer
and are more resistant to natural diseases and stress-related disorders.
The researchers reported their findings in the online journal of
the Federation of the American Societies for Experimental Biology.
