Reﬁned wheat and rice noodles are common staple foods throughout Asia today, so replacing some of these foods with whole grain versions could go a long way in improving health. To test the impact, researchers randomly assigned 84 healthy adults (some with mildly high cholesterol) in Taiwan to an oat noodle group or a reﬁned wheat noodle group, providing them with 100 grams (about 1 ½ cups cooked) of their respective noodles across 1 or 2 meals each day for 10 weeks. After the 10-week study, the oat group reduced their total cholesterol by 17% and LDL-c (“bad”) cholesterol by 19% compared with the wheat noodle group. The oat noodle group also signiﬁcantly lowered their blood pressure by 7-11%, but the wheat noodle group did not. The beneﬁts tended to be stronger in people who started the study with slightly high cholesterol, but the results were still statistically signiﬁcant for the group as a whole.
