Red and white meat equally bad for cholesterol according to a new study

New research by researchers at the Children’s Hospital Oakland Research Institute (CHORI) reverses the belief about the consumption of red and white meat. According to the “popular belief” consuming white meat has a lesser effect on the increase in cholesterol level than consuming red meat. However, the study published in the American Journal of Clinical Nutrition was the first to surprise the researchers themselves.

According to their findings, there would be no difference between consuming high levels of red meat or white poultry. Both contributed to higher blood cholesterol levels than, for example, the consumption of a comparable amount of plant proteins during observations. And this regardless of the high levels of saturated fat in the diet of the patients examined: “Their effects on cholesterol are identical when the levels of saturated fat are equivalent,” reports Ronald Krauss, the senior author of the study and professor of medicine at UCSF Benioff Children’s Hospital in Oakland.

According to the results, consuming large amounts of saturated fat increases the concentrations of large cholesterol-enriched LDL (low-density lipoprotein) particles that still have a weaker connection with cardiovascular disease than smaller LDLs. Also according to the results, both red and white meat increased the quantities of large LDLs.

These results contrast with the various recommendations regarding the use of white meat compared to red meat, which has become quite unpopular in recent years among health professionals and those who are more attentive to nutrition. In any case, this “equality” between red meat and white meat can currently only be linked to their effects on blood cholesterol: other possible negative effects of eating red meat compared to white meat, such as a greater contribution to heart disease, would still be at stake.

Six billion people may be at risk of dengue fever by the end of the century

A new study takes into account the great threat of dengue fever that is spreading alarmingly in various parts of the world. According to the research, which appeared in Nature Microbiology, the relevant virus could be a source of real risk for more than 6 billion people by the end of this century. Specifically, 20% of the world’s population could contract the virus in 2080 in the most terrible, but also the most pessimistic, hypothesis.

The areas where the spread could increase, and in a fairly massive way, are the southeastern United States, the coastal areas of China and Japan and the internal regions of Australia. These results were obtained by a research group that analyzed in particular data on climate change, urbanization and the planet’s resources to understand the indirect spread of the virus.

In any case, the major changes, at the level of spread, are expected in those areas where dengue fever is already a very real danger and where the disease can be defined as endemic. There is talk of various areas of the African continent, in particular the regions of the Sahel and southern Africa. Surprisingly, the data analyzed does not show a future greater spread of the disease in Europe compared to other areas further away from Africa and less subject to illegal immigration from the latter.

In fact, climate change will contribute to the expansion of dengue, as Oliver Brady, assistant to the London School of Hygiene & Tropical Medicine and one of the authors of the study, points out, but other important factors will also be the increase of the human population and urbanization in tropical areas. All these factors will allow mosquitoes to spread and thrive and therefore the virus it carries will do the same.
