Calcium and heart disease: What's the connection?

People sometimes wonder if the calcium they consume affects their calcium score, a test that measures calcium in the heart's arteries to predict heart disease risk. But a 2024 study linked higher calcium intake to a lower risk of heart calcifications. Calcium helps lower blood pressure, possibly by improving the function of the lining of blood vessels. Older adults should make sure they're getting the recommended amount of calcium in their diets. Good sources include dairy products, tofu made with calcium sulfate, almond or oat milk, canned sardines or salmon, collard greens, and kale.

Different types of rapid heart rhythms

Atrial fibrillation and supraventricular tachycardia are rapid, abnormal heart rhythms that originate in the upper part of the heart. But they tend to arise at different ages, and they require different treatments.

Eating ultra-processed food may shorten life span among older adults

Older adults who consume ultra-processed foods as a substantial part of their diet have a higher risk of early death than those who eat less of these foods.

Cutting meat intake by a third could reduce rates of heart disease

A 2024 report suggests that rates of cardiovascular disease, diabetes, and colon cancer would fall substantially if people ate less red and processed meat.

Gratitude linked to longer life and fewer heart-related deaths

A 2024 study suggests that older women with higher scores on tests to assess gratitude may live longer than those with lower scores. Most of this benefit seems to come from preventing deaths from heart disease.

More evidence links flu infection to heart attack risk

A diagnosis of influenza (flu) was linked to a sixfold risk of heart attack over the following week, according to a 2024 report.

Gratitude enhances health, brings happiness - and may even lengthen lives

Gratitude has the power to boost well-being, improve sleep, lessen depression, and help heart health. Now new data from the long-term Nurses' Health Study shows that it may extend lives. How can you jump start a gratitude practice in your life?

When fear strikes the heart: Post-traumatic stress disorder

People with post-traumatic stress disorder (PTSD) are especially vulnerable to cardiovascular problems, including a 40% increased risk of heart attack. The amygdala, a brain structure involved in processing anxiety, fear, and stress, is overactive in people with PTSD. But these people also have decreased activity in the ventromedial prefrontal cortex, which is responsible for regulating emotions and dampening the fear response. This brain activity imbalance triggers chronic activation of the body's "fight-or-flight" response. The resulting physiological changes appear to underlie the development of atherosclerosis.

Body roundness may beat body mass for identifying risky fat

Body roundness index, which is calculated based on a person's height, waist, and hip size, might be a more accurate measurement than body mass index for predicting weight-related health risks, according to a 2024 study.
