A study published in PNAS suggests that humans' unique genetic adaptation to meat-rich diets has increased lifespan but also made us more susceptible to diseases of aging such as cancer, heart disease, and dementia. ApoE4 carriers have higher rates of early onset coronary heart disease and Alzheimer's disease.
A new study suggests that reducing salt in the American diet by just one-half teaspoon per day could prevent nearly 100,000 heart attacks and 92,000 deaths annually. This reduction in salt intake could also save the US around $24 billion in healthcare costs.
A study published in PLoS ONE found a correlation between DNA methylation and heart failure, suggesting that environmental factors may play a key role in the development of the disease. The researchers compared DNA from diseased hearts with healthy hearts and found distinct 'marks' on the genome

Two Australian research studies reveal that 50% of people over 30 do not have sufficient risk factor information recorded, and only 20% with high risk receive all recommended treatments. Indigenous healthcare sites show better patient management, with 44% prescribed appropriate medicines.
A nonagenarian researcher, Fred Kummerow, has filed a petition with the FDA to ban trans fats from the American diet. His research suggests that trans fats contribute to the two main causes of heart disease: blood clots and atherosclerosis. The FDA has 180 days to respond to his petition.
The guidelines focus on non-cardiac surgery, with an emphasis on assessing clinical risk factors and testing for ischaemic heart disease. Recommended medications include beta-blockers, statins, aspirin, and angiotensin converting enzyme inhibitors.
A study of 559 healthy women found a link between hopelessness and increased thickness of neck arteries, which can be a precursor to stroke. The researchers discovered that hopelessness was independently associated with cardiovascular disease risk in women without clinical symptoms of heart disease.
A new study found that hopelessness is associated with increased thickening of neck arteries in healthy women, even before they develop clinically relevant cardiovascular disease. Apathy among stroke survivors also impeded recovery and was linked to poor cognitive status and functional decline.
The number of people aged 60 or over in South Africa is projected to triple by 2025, leading to a doubling of cardiovascular deaths. The burden of non-communicable diseases is expected to increase as antiretroviral therapy reduces mortality from HIV/AIDS.
Heat waves pose a significant threat to older adults and individuals with chronic diseases, who are more susceptible to heat-related illnesses due to impaired thermoregulation. Air conditioning and working fans can reduce the risk of mortality by up to 80% and 30%, respectively.
Whole grain cereals contain surprisingly large amounts of healthful antioxidant substances called polyphenols, comparable to fruits and vegetables. Raisin bran has the highest amount of antioxidants per serving due to raisins.
