A recent 5 year study of older (75.1 ± 2.7 years) women had an incidental finding. I am referring to a randomized, double-blinded, placebo-controlled study called the ‘Calcium Intake Fracture Outcome Study’ (CAIFOS). It was designed to look at calcium and bone health but noted that eating more broccoli and other cruciferous vegetables was associated with cleaner arteries. Great find! Cruciferous vegetables include watercress, kale, Bok Choy, radishes and more. Those women who reported at least three servings of these vegetable daily (from food frequency questionnaires) had a significant (about 5.0%) lower mean and maximum common carotid artery middle wall thickness compared with those eating less than two servings a day. Carotid Arteries are large blood vessels on each size of your neck taking oxygen rich blood up to our brain, a pulse from pass through a normal diameter of 35mm. Other categories of vegetables — leafy greens, legumes, and such — did not show any significant associations.
Study resulted finding that taking Calcium at 1200 mg daily did not increase atherosclerosis aka ‘hardening of the arteries’.
Doctor’s Orders: Eat cruciferous no matter your sex!
