Swedish researchers say eating milk chocolate every week may help save men from having a stroke.

The study, published in the journal Neurology, followed more than 37,000 men ages 49-75 over a ten year period. The men filled out their own food logs and were asked specifically about their chocolate consumption. The team then cross-referenced data on stroke cases.

Those who ate the largest amount of chocolate - about 1/3 of a cup per week - had a 17% lower risk of stroke than those who did not eat any chocolate at all.
