"Dairy imports from China account for less than 1percentt of total dairy products imported to this country annually".
Dairy intake from food records did not differ between groups at baseline; baseline intake for all participants (mean±standard error) was 0.45±0.05 servings/day for low-fat dairy products and 1.44±0.06 servings/day for total dairy products.
"This meta-analysis showed there were no associations between total dairy, high- and low-fat dairy, milk and the health outcomes including all-cause mortality, coronary heart disease or cardiovascular disease," says the report, published in the European Journal of Epidemiology.
There were no significant differences in age among 3 ethnic groups, while milk and total dairy consumption did vary by ethnic group with Blacks consuming the least milk g and Whites consuming the most total dairy kcal.
Total dairy consumption averaged 1.05 servings per person per day, with a range of 0 5 servings.
When stratifying perchlorate dose by total dairy servings, geometric means of perchlorate dose increased with increasing dairy consumption (Figure 2) (nonparametric Kruskal-Wallis test, p = 0.24).
We used the nonparametric Kruskal-Wallis test to compare levels of perchlorate dose by total dairy servings and perchlorate concentration in produce [21].
For girls age 9 12 yrs Cox regression was also used to ascertain whether frequency or amount of milk intake or total dairy kcal affected the probability of reaching menarche before age 12 yrs.
Among the 9 12 yr olds, Cox regression indicated that neither total dairy kcal, calcium and protein, nor daily milk intake in the past 30 days contributed to early menarche.
Overweight girls reported drinking significantly less milk than those with lower BMIs, although 30 day frequency of milk consumption and total dairy kcal and other nutrients did not vary by overweight status.
As shown in Table 4, after controlling for birth weight, ethnic group and total kcal, total dairy kcal, protein or calcium, and frequency of milk intake over the past 30 days each had no association with the risk of menarche prior to 12 yrs in Cox regression.
