在网上看了这一篇，说在健康人群中，白细胞低于4的所占比例为7%－8%，是属于最健康的那一组。

"。。。we had hypothesized that the participants with subnormal leukocyte counts would have the healthiest states among apparently healthy adults。。。  In accordance with our hypothesis, the results show that the subnormal leukocyte count category had the lowest prevalence and incidence of MS."

"In conclusion, this large-scale epidemiological study has shown that subnormal leukocyte counts were independently related to the lowest prevalence and incidence of MS. Based on these findings, we have constructed the novel hypothesis that a subnormal leukocyte count is not a reference value for screening cases of reduced leukocyte counts, but is maybe the healthiest range for prevention and treatment of MS or CVD among an apparently healthy population. "

而且白细胞低的，白蛋白却是正常的，所以结论是，白细胞低并不意味着饮食营养不良或是营养不良引起的。天津13000多人的流行病学统计
