Nick Norwitz, a doctorate student at Harvard University, found that contrary to the beliefs of many experts, his cholesterol levels actually dropped. After the month-long experiment that saw him eat the equivalent of 24 eggs per day his low-density lipoprotein (LDL) levels, or 'bad' cholesterol, fell by 18 percent. Experts have demonized cholesterol in eggs for decades, warning that eating them may cause a surge in LDL levels and raise the risk of complications. Dr Norwitz has a PhD in human brain metabolism from the University of Oxford and is completing his medical doctorate at Harvard University.
