Japanese-American men who don't eat a diet rich in vitamin D have an increased risk of stroke later in life, according to a new, long-term study. The study included nearly 7,400 Japanese-American men living in Hawaii. They were between the ages of 45 and 68 in the mid- to late-1960s, when they were first examined and interviewed about their eating habits.
