In 1960 the consumption of certain
food items in 25 000 subjects was recorded in California,
about half of whom were lacto-vegetarians. Milk drinking
was quantified simply as two glasses or more per day. In
subjects with this intake, the relative risk of coronary death
during the following 20 years, compared with those who
drank no milk, was 0.94 in men and 1.11 in women. It is not
possible to estimate confidence limits for these ratios.
