MedicalResearch.com: What is the background for this study? What are the main findings?
Response: -The consumption of red and processed meat has been associated with risks of importance to public health including cardiovascular diseases and cancer.
Several studies have found that red and processed meat intake was associated with an increased risk of mortality. However, levels of meat intake in those studies were relatively high. It remains of interest whether even relatively low intake levels of red and processed meat might be associated with greater mortality, compared to zero intake.

MedicalResearch.com: What is the background for this study?
Response: Dietary cholesterol is a common nutrient in human diet. Eggs, specially egg yolks, are the single richest source of dietary cholesterol among all commonly consumed foods. The associations between dietary cholesterol consumption and cardiovascular disease and mortality remain controversial despite decades of research. Eating less than 300 mg of dietary cholesterol per day was the guideline recommendation before 2015. However, the most recent 2015-2020 Dietary Guidelines for Americans no longer include a daily consumption limit for dietary cholesterol and recommend weekly egg consumption as part of the healthy US-style eating pattern. Whether these recommendations are appropriate have been intensely debated.

MedicalResearch.com: What is the background for this study?
Response: Urban living is one of the most well-established risk factors for adult psychotic disorders such as schizophrenia. However, less is known about the role of the urban environment in subclinical psychotic experiences in childhood and adolescence, such as hearing voices and extreme paranoia. These early psychotic experiences are a developmental risk factor for adult psychotic disorders and a range of other serious mental health problems such as depression and anxiety.
It is therefore important that we understand what factors might contribute to the development of early psychotic experiences so that we might be able to intervene and prevent their onset and progression.
In a cohort of over 2000 UK-born children (The Environmental Risk Longitudinal Twin Study), we have previously shown that subclinical psychotic experiences are also around twice as common among children and teenagers raised in urban versus rural settings. We have also shown that this appears to be partly explained by social features in urban neighbourhoods such as higher crime levels and lower levels of social cohesion.
However, no studies have examined the potential link between air pollution and psychotic experiences. This is despite air pollution being a major health problem worldwide (particularly in cities), and despite emerging evidence linking air pollution to the brain.
