The negative effects of vitamins: Study

Study raises more questions about the health benefits of vitamins.

A new Biology Letters  paper raises more questions about the benefits of vitamins as a health supplement. High doses of dietary antioxidants such as vitamins are claimed to slow the process of cellular aging by lessening the damage to proteins, lipids and DNA caused by free radicals. Some research has found that the longevity of mice could be extended by administering particular vitamin supplements, despite the supplements’ limited effectiveness in reducing free radical damage. However, the opposite was found to be true in voles in a new study.

Billions of engineered nanoparticles in foods and pharmaceuticals are ingested by humans daily, and new Cornell research warns they may be more harmful to health than previously thought.

A research collaboration led by Michael Shuler, the Samuel B. Eckert Professor of Chemical Engineering and the James and Marsha McCormick Chair of Biomedical Engineering, studied how large doses of polystyrene nanoparticles — a common, FDA-approved material found in substances from food additives to vitamins — affected how well chickens absorbed iron, an essential nutrient, into their cells…
