Lean meat and heart health

The general health message to the public about meat consumption is both confusing and misleading. It is stated that meat is not good for health because meat is rich in fat and cholesterol and high intakes are associated with increased blood cholesterol levels and coronary heart disease (CHD). This paper reviewed 54 studies from the literature in relation to red meat consumption and CHD risk factors. Substantial evidence from recent studies shows that lean red meat trimmed of visible fat does not raise total blood cholesterol and LDL-cholesterol levels. Dietary intake of total and saturated fat mainly comes from fast foods, snack foods, oils, spreads, other processed foods and the visible fat of meat, rather than lean meat. In fact, lean red meat is low in saturated fat, and if consumed in a diet low in SFA is associated with reductions in LDL-cholesterol in both healthy and hypercholesterolemia subjects. Lean red meat consumption has no effect on in vivo and ex vivo production of thromboxane and prostacyclin or the activity of haemostatic factors. Lean red meat is also a good source of protein, omega-3 fatty acids, vitamin B12, niacin, zinc and iron. In conclusion, lean red meat, trimmed of visible fat, which is consumed in a diet low in saturated fat does not increase cardiovascular risk factors (plasma cholesterol levels or thrombotic risk factors).

Obesity, a worldwide epidemic related to heart disease and stroke: group IV prevention/treatment

Obesity is a worldwide problem, not just an issue for industrialized nations. Therefore, we need to examine opportunities for prevention and treatment from a global perspective.

High stakes principalship - sleepless nights, heart attacks and sudden death accountabilities: reading media representations of the US principal shortage

The possible shortage of applicants for principal positions is news in both Australia and abroad. We subject a corpus of predominantly US news article to deconstructive narrative analysis and find that the dominant media representation of principals' work is one of long hours, low salary, high stress and sudden death from high stakes accountabilities. However reported US policy interventions focus predominantly on professional development for aspirants. We note that this will be insufficient to reverse the lack of applications, and suggest that the dominant media picture of completely unattractive principals' work, meant to leverage a policy solution will perhaps paradoxically perpetuate the problem. This picture is also curiously at odds with research that reports high job satisfaction among principals. We suggest that there is a dominant binary of victim and saviour principal in both media and policy which prevents some strategic re-thinking about how the principalship might be different.
