• Refined Grains May Raise CAD Risk. Refined grains may increase risk of developing premature coronary artery disease (CAD), according to an Iranian study. Data from more than 2,000 men and women, aged 60 years and younger and 70 years and younger, respectively, about half with premature CAD and half with normal coronary arteries, was used to assess dietary intake. Higher intake of refined grains was associated with higher risk of CAD. Whole grain intake was inversely related to premature CAD.

• Unprocessed Foods Linked with Lower Crohn’s Disease Risk. Consumption of more unprocessed or minimally processed foods was associated with a lower risk of Crohn’s disease (CD), researchers say. Over 400,000 healthy volunteers in eight European countries completed food frequency questionnaires over 13 years. People who ate the most unprocessed foods had the lowest risk of CD versus those eating the least. Fruits and vegetables were linked with the lowest risk of CD.

• Plant-Based Diet May Reduce Hot Flashes. A low-fat, plant-based diet that is rich in soy foods may reduce the frequency and severity of postmenopausal hot flashes and associated symptoms, according to researchers. Postmenopausal participants experiencing two or more hot flashes a day followed either a diet with no animal products, reduction in fat intake, and the addition of a half-cup serving of soybeans daily or no dietary changes. Participants who made dietary changes reduced symptoms by 88 percent and reduced weight by an average of eight pounds over the 12-week study. Those who made no changes reduced symptoms by 34 percent.
