In a 2024 study, people with a habit of eating dark chocolate-about an ounce a day-were less likely to develop diabetes compared to those who didn't consume it.

Social media sources may share misleading information about canola, soybean, and other seed oils. But these oils, which consist mostly of unsaturated fat, can be a good source of heart-healthy fat when combined with whole, fresh foods rather than in processed foods like crunchy, salty, or sweet snack foods. Consuming unsaturated fat in place of saturated fat (found mainly in animal-based foods) is linked to a lower risk of heart attack and death from heart disease.

A 2024 study involving more than 72,000 healthy people ages 40 to 79 found that those whose sleep and wake times fluctuated most had a 26% higher risk of having a heart attack, stroke, or similar problem, compared with those whose sleep patterns fluctuated least.

According to a 2024 study, people who reported work-related stress were more likely to have unfavorable measures of cardiovascular health than those without that stress.

Each year, an estimated 700,000 Americans suffer from cardiac arrest, when the heart abruptly stops beating, causing the person to collapse and stop breathing. Immediately performing hands-on cardiopulmonary resuscitation (CPR) can more than double the odds of survival. Experts recommend that all adults should take an in-person CPR class at least once and have a refresher course every two to three years.

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.

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.

Both the Mediterranean diet and vegan diet can help stave off heart disease. But while the Mediterranean diet is slightly more expensive than the standard American diet, a vegan diet is 19% lower in cost, according to a 2024 analysis.
