A 10-year analysis of ischemic heart disease deaths among 34,492 postmenopausal women showed that those who consumed the most whole-grain had the lowest risk. The positive effect was attributed to increased intake of phenols, vitamins, and phytoestrogens.
Researchers investigated enteral supplements' impact on AIDS patients, finding net increases in protein and energy intakes. However, fat-free mass did not increase for the group as a whole, but was inversely correlated with baseline synthesis of fat.
Scientists plan to use stereo imaging to analyze the three-dimensional structures of the Sun's corona, which can help predict explosive events like coronal mass ejections and solar flares.
Researchers discovered a possible link between elevated blood homocysteine levels and Alzheimer's disease, with lower folate and vitamin B12 levels also observed. Long-term clinical trials are needed to determine if lowering homocysteine levels can prevent or delay the progression of the disease.
A fortified orange-flavored drink significantly improved nutritional deficiencies in Tanzanian children, leading to increased weight gain and height. The drink supplied essential vitamins and minerals, improving iron status and reducing anemia in many cases.
A new study found that consuming high levels of antioxidants like beta carotene, selenium, and vitamins C and E can significantly improve lung function, comparable to the difference between a nonsmoker and a long-term smoker. The research suggests that these antioxidants may help prevent asthma, emphysema, and chronic bronchitis.
A new study by University at Buffalo researchers found that smoking during pregnancy increases the risk of pre-term birth, low-birth weight babies, and small-for-gestational-age infants. Despite taking prenatal vitamins, these risks remain higher for smokers compared to non-smokers.
