Coffee: A heart-healthy brew?

Coffee drinking has been linked to a lower risk of dying of heart disease. Coffee contains potent anti-inflammatory substances called polyphenols that may improve blood sugar control and help blood vessels contract and relax. Although the caffeine in coffee may help people control their weight, it can trigger a short-term rise in blood pressure and heart rate. Filtered coffee, which removes substances that may raise LDL (bad) cholesterol, appears to be a better option than unfiltered coffee.

Air pollution: An invisible threat to your heart

Exposure to microscopic particles called PM2.5 in air pollution may increase a person’s risk of heart attack, stroke, and heart rhythm disorders. The tiny particles pass from the lungs into the bloodstream, triggering inflammation and other cell-damaging processes. Air pollution comes mainly from coal-fired power plants, industrial factories, and motor vehicles. To limit exposure, people should try to avoid exercising outdoors near busy roads or industrial areas.

Short on slumber

Most adults need seven to nine hours of sleep each night, but more than one-third consistently sleep fewer than seven. Reasons for poor sleep include pregnancy, menopausal night sweats, medication use, sleep disorders, and various illnesses. Sleep deprivation can raise the risks for such conditions as diabetes, certain cancers, obesity, dementia, depression, and heart disease. To promote sounder sleep, people can keep consistent sleep-wake schedules, reduce intake of caffeine and alcohol, and avoid using electronic devices before bed.

Does inflammation contribute to infertility?

Infertility affects millions of people worldwide. Chronic inflammation has been linked to many health conditions and some research suggests it might be a contributing factor for some cases of infertility. And if true, would an anti-inflammatory diet or lifestyle boost fertility?

Easy ways to keep inflammation in check

Certain healthy habits can fight chronic inflammation, such as eating a healthy diet, exercising regularly, getting enough sleep, maintaining good oral health, and reducing stress. If adopting all those habits seems daunting, taking little steps in their direction can help. For example, a person might eat fatty fish twice a week, since it contains omega-3 fatty acids known to reduce inflammation; or go for a quick daily walk, since exercise may increase the production of hormones that help keep inflammation in check. The combined effects of many little habits can eventually add up to keep people healthier.

Do fermented foods live up to the hype?

Fermented foods and drinks such as kimchi, kombucha, and tempeh are increasingly popular, adding to mainstays such as yogurt, sauerkraut, and beer. Heat and bright lights during manufacturing can destroy some beneficial probiotics. Fermented products can ease digestion, dampen inflammation, boost nutrient absorption, and battle harmful bacteria. People should look for product labels that say "live and active cultures" and avoid shelf-stable versions, which don't contain probiotics.

Treatments for rheumatoid arthritis may lower dementia risk

Inflammation is the hallmark of rheumatoid arthritis, and is also thought to play a role in the development of dementia. Could the inflammation-suppressing medicines for RA lower risk of dementia? Some research points in that direction, but more is needed.

Atrial fibrillation after surgery: Common and undertreated?

After surgery unrelated to the heart, a diagnosis of atrial fibrillation (afib) may be more common than previously thought. These cases, which may constitute 13% of new afib diagnoses, appear to be undertreated.

Too little sleep may be hard on your heart

Not getting sufficient sleep may harm the cardiovascular system by triggering physiological and hormonal changes that increase blood pressure, blood sugar, and blood levels of substances that indicate inflammation. People who don't regularly get at least seven hours of sleep a night should assess their daily habits to look for ways to improve, such as by establishing an earlier bedtime and turning off all electronic devices at least an hour before bedtime.

How a fiber-rich diet promotes heart health

Fiber-rich diets may lower the risk of heart attack and stroke, in part by decreasing inflammation. This benefit appears to be facilitated by the breakdown of prebiotic fiber in the gut microbiome to create short-chain fatty acids. These compounds circulate through the bloodstream and interact with specific receptors on cells that quell inflammation. Short-chain fatty acids may also play a role in keeping blood sugar, blood pressure, and cholesterol levels in check, as well as helping to prevent harmful blood clotting.
