Dogs and owners share emotional and physiological changes

In a 2024 study, researchers found that the heart rate variability of a dog and its owner mirror each other during interactions, which may reflect the strong emotional connection between humans and their dogs.

Getting fiber while avoiding gluten

A gluten-free diet (which omits wheat, rye, and barley) may be low in fiber, a nutrient that's important for cardiovascular health. People who avoid gluten should try to include gluten-free grains and seeds in their menus, such as amaranth, buckwheat, millet, sorghum, teff, and quinoa. Carrots, celery, kale, and kiwis contain mostly insoluble fiber, which helps you feel full and encourages regular bowel movements. Beans, nuts, seeds, and fruits (such as berries, apples, pears, and citrus fruits) are good sources of soluble fiber, which helps lower cholesterol and blood sugar.

Gum disease and heart health: Probing the link

About two-thirds of people over 65 have periodontal disease, which is linked to a higher risk of heart disease. Shared risk factors such as smoking and an unhealthy diet may explain the association, but bacteria and inflammation could be a common thread. The bacteria responsible for periodontal disease can travel to blood vessels throughout the body and have been found in the fatty debris (atherosclerosis) that clogs arteries located far from the mouth-and in blood clots from people who have experienced heart attacks.

Flavonoid-rich diet linked to lower risk of plaque in neck, leg arteries

According to a 2024 study, eating foods rich in beneficial plant compounds called flavonoids may lower the risk of atherosclerosis in the arteries of the legs and neck. Good sources of flavonoids include tea, apples, pears, peaches, and oranges.

Incorrect arm position may skew blood pressure readings

Letting your arm dangle or rest in your lap (instead of being supported at heart level, as is recommended) during a blood pressure check can cause a falsely high reading, according to a 2024 study.

Create a customized home workout space

Having a home workout area can make it easier to meet daily exercise goals, especially during the winter months, when weather conditions may make outdoor exercise impractical. If space allows, people may want a treadmill or other machine that's suitable for any health issues they may have. For example, people with hip or knee arthritis often find that a stationary bike is more comfortable for arthritic joints. For strength training, resistance bands or tubes are ideal for beginners because they're affordable, versatile, and easy to use. Scheduling a few sessions with either a physical therapist or certified personal trainer can help people learn and practice proper form.

Under-the-radar heart risks

Research has shown that men can have a higher risk for heart attacks and strokes if they suffer from certain medical conditions that might seem unrelated to heart disease. These conditions include erectile dysfunction, gum disease, peripheral artery disease, and urinary tract infections. Many factors that contribute to heart disease like inflammation and fatty deposits in the arteries are involved in these other conditions.

Harvard study pegs the worst ultra-processed foods for your heart

A 2024 study of more than 200,000 adults, combined with findings from 19 other studies (for a total of 1.25 million people), tied eating ultra-processed foods-particularly sugary drinks and processed meats-to an increased risk for heart disease.

Seafood selections that help your heart - and our planet

Choosing seafood that's lower on the food chain (such as herring, sardines, clams, and oysters) is beneficial for both cardiovascular health and the health of the environment. Finfish, crustaceans, mollusks, cephalopods, aquatic plants, and seaweed are all considered aquatic foods. Replacing terrestrial animal proteins such as beef, pork, and chicken (especially processed forms) with aquatic foods helps people eat less saturated fat and more omega-3 fatty acids. Also, producing aquatic foods generates far fewer greenhouse gases than producing terrestrial foods.
