Wheat

Early exposure to whole grain foods can shape food preferences later in life, so researchers wonder if it may be worthwhile to start with infants. Infant cereals are one of the first solid foods given to babies to compliment breast milk or formula and are often made from refined grains like white rice or pearled barley. In this study, researchers in Spain worked with parents of 81 infants (4-24 months old) to test the acceptability of 30% whole grain infant cereals (made with whole wheat), compared with a popular refined infant cereal. (Whole wheat was chosen to comply with European infant legislation, to make sure that the amount of fiber was appropriate.) After trying each of the cereals for 3 days in a row, infants were just as likely to accept and finish the whole grain cereal as they were the refined cereal. The researchers concluded that infant cereals are an opportunity to expose young people to whole grains earlier in life, to build a taste for them.

An estimated 1 in 8 women in the US will develop invasive breast cancer over her lifetime, so preventive lifestyle choices are an important area of research. To see how diet plays a role, Harvard scientists analyzed the grain food choices of 90,516 pre-menopausal women, and monitored their health outcomes for 22 years. After adjusting for known breast cancer risk factors, those eating 1.5 servings of whole grains per day were 18% less likely to get pre-menopausal breast cancer than those eating hardly any whole grains (0.2 servings/day). This relationship was no longer significant after adjusting for fiber, suggesting that the fiber in whole grains may play a protective role. When looking at individual grain foods, brown rice and pasta (white or whole grain) were associated with a lower risk of overall breast cancer risk, while white bread was linked with a higher risk of overall breast cancer.
